Simple family dinner favorite

This hearty Ground Beef and Potato Bake transforms simple, everyday ingredients into a satisfying meal that brings the whole family running to the dinner table. The layers of seasoned ground beef, thinly sliced potatoes, and creamy sauce create a comforting casserole that feels like a warm hug at the end of a long day. When the aroma of this dish fills your kitchen, you'll understand why it's become a staple in countless family recipe collections.

I discovered this recipe during a particularly hectic season when my children were young and involved in different after-school activities. One evening, desperate for something quick yet hearty, I remembered my grandmother's potato and beef casserole. Working from memory, I threw it together while helping with homework. When my typically picky 7-year-old asked for seconds, I knew I'd found our new regular rotation meal. Since then, it's become the dish I rely on when comfort food cravings strike or when I need to feed a crowd without spending all day in the kitchen.

Ingredients

• 1 pound ground beef: Forms the protein-rich foundation of this casserole. Look for lean ground beef (85/15 or 90/10) that provides good flavor without excessive grease. The meat should have a bright red color with some visible marbling for best flavor. If possible, choose grass-fed beef for enhanced nutrition and taste, though conventional works perfectly well. When cooking, break it into small, even crumbles to distribute the savory flavor throughout each bite.
• 1 can (10.5 oz) condensed cream of mushroom soup: Creates the creamy binding sauce that brings everything together. Select a quality brand for best results as it forms the base of your sauce. The concentrated flavors in this soup provide depth without requiring multiple ingredients or extensive seasoning. The thick texture helps the casserole hold together when served, while its savory notes complement both the meat and potatoes beautifully.
• ½ cup milk: Thins the condensed soup to the perfect consistency while adding richness. Whole milk creates the creamiest result, but 2% or even skim will work if that's what you have on hand. The milk helps create a silky sauce that coats each component of the casserole. Fresh milk works best, as the flavor is an important component of the sauce.
• 1 medium onion, finely chopped: Provides essential aromatic flavor and subtle sweetness that balances the richness. Look for firm onions without soft spots. Yellow onions offer the perfect balance of flavor for this dish, though white onions work well too. Chop the onion into small, even pieces to ensure it cooks thoroughly and distributes evenly throughout the casserole. The onion should be fresh and pungent when cut.
• 4-5 medium potatoes: Form the hearty, filling base of this comfort food classic. Russet potatoes are ideal thanks to their starchy nature and ability to absorb flavors while maintaining their structure. Choose firm potatoes without green spots or sprouts. They should feel heavy for their size and have smooth skin with minimal blemishes. Slice them to a consistent thickness (about ⅛ inch) so they cook evenly.
• 1 teaspoon salt: Enhances all the other flavors in the dish. A quality sea salt or kosher salt with larger grains provides better flavor control than standard table salt. Proper seasoning is critical to bring out the natural flavors of the potatoes and beef. You may need to adjust slightly based on the sodium content of your soup.
• ½ teaspoon black pepper: Adds gentle warmth and depth that complements the savory components. Freshly ground pepper provides significantly better flavor than pre-ground. The subtle heat balances the creaminess of the sauce. Black pepper should be fragrant when ground, indicating freshness.
• 1½ cups shredded cheddar cheese: Creates that irresistible golden, melty top layer that makes this casserole special. Sharp or medium cheddar provides the best flavor contrast with the creamy sauce. Freshly grated cheese melts more evenly than pre-shredded varieties, which contain anti-caking agents. Look for cheese with good color and a firm texture, grating it just before using for the freshest taste and best melting properties.

Step-by-Step Instructions

Step 1: Prepare your kitchen and ingredients

Begin by preheating your oven to 350°F, giving it plenty of time to reach the proper temperature while you prepare the casserole. This moderate heat allows the potatoes to cook through without burning the top. Pull out a 9x13 inch baking dish and lightly grease it with cooking spray or butter to prevent sticking. This step is important for easy serving later. Gather all your ingredients and measuring tools before starting to make the assembly process smooth and efficient. If you're using a mandoline for slicing potatoes, set it up now. This preparation step saves time and reduces stress during the cooking process.

Step 2: Brown the ground beef thoroughly

Place a large skillet over medium-high heat and allow it to get fully hot before adding the ground beef. Adding meat to a properly heated pan ensures better browning and flavor development. Add the beef to the hot skillet and break it into small, uniform crumbles using a wooden spoon or spatula as it cooks. Stir occasionally to ensure even browning on all sides. Cook until no pink remains, typically 5-7 minutes. The meat should be evenly browned with some caramelized bits for maximum flavor. Once fully cooked, carefully drain off any excess grease by tilting the pan slightly and spooning out the fat, or by transferring the meat to a paper towel-lined plate. Properly drained meat prevents the final casserole from becoming greasy.

Step 3: Prepare the potatoes with care

While the beef is cooking, wash the potatoes thoroughly under cool running water, scrubbing gently to remove any dirt. Pat them dry with a clean kitchen towel. Using a sharp knife or vegetable peeler, remove the skin from each potato, taking care to remove only a thin layer to preserve as much of the potato as possible. With a sharp knife or mandoline slicer, cut the potatoes into thin, uniform slices approximately ⅛-inch thick. Consistent thickness is crucial for even cooking. If using a knife, try to maintain a steady, even pressure for uniform slices. If some slices end up thicker than others, you can set them aside to use in the bottom layer where they'll have more time to cook through. Once sliced, you can place the potatoes in cold water briefly to prevent discoloration, but be sure to drain and pat them dry before assembling the casserole to prevent excess moisture.

Step 4: Create the creamy sauce base

In a medium mixing bowl, empty the contents of the condensed cream of mushroom soup. Add the milk gradually, whisking continuously to create a smooth consistency without lumps. This gradual addition helps achieve the perfect sauce texture. Add the finely chopped onion, distributing it evenly throughout the sauce. The onion will partially cook in the oven, adding flavor while softening into the sauce. Season the mixture with salt and pepper, whisking to incorporate evenly. Taste the sauce and adjust seasonings if needed, keeping in mind that the cheese will add some saltiness later. The sauce should be pourable but not watery – it will thin slightly as the casserole bakes from the natural moisture in the potatoes.

Step 5: Assemble the casserole in even layers

Begin the assembly process by spreading a thin layer of the creamy sauce across the bottom of your greased baking dish. This prevents the first layer of potatoes from sticking and starts the flavor building. Arrange a single layer of potato slices over the sauce, slightly overlapping them to create a solid foundation. The overlapping ensures there are no gaps and every bite includes potato. Distribute half of the browned ground beef evenly over the potatoes, breaking up any large clumps for more even distribution. Pour approximately one-third of the remaining sauce over the beef layer, spreading it to cover evenly. The sauce should penetrate between the layers, binding everything together. Create a second layer of overlapping potato slices, followed by the remaining beef and more sauce. Finish with a final layer of neatly arranged potato slices and pour the remaining sauce over the top, ensuring all potato edges are covered to prevent them from drying out during baking.

Step 6: Cover and bake until potatoes are tender

Cover the baking dish tightly with aluminum foil, crimping the edges to create a good seal. This traps moisture and heat, essentially steaming the potatoes to ensure they cook through properly. Place the covered dish in the preheated oven on the center rack where heat circulates most evenly. Bake for 60 minutes, then carefully remove the foil (watch for hot steam) and test the potatoes by inserting a fork or knife into the center of the casserole. It should slide easily through the potatoes with no resistance. If you encounter any firmness, recover the dish and continue baking for an additional 15-20 minutes. Cooking time may vary based on potato thickness and your specific oven. The patience required during this step is rewarded with perfectly tender potatoes that melt in your mouth.

Step 7: Add cheese for a golden finish

Once the potatoes are tender throughout, remove the foil completely and discard it. Evenly sprinkle the shredded cheddar cheese over the entire surface of the casserole, making sure to reach all the way to the edges. The even distribution ensures each serving will have that perfect cheesy top. Return the uncovered dish to the oven and bake for an additional 5-10 minutes. Watch carefully during this final baking phase – you want the cheese to melt completely and develop some golden spots without burning. The color change from yellow to golden amber indicates the development of complex flavors in the cheese as it caramelizes slightly. This golden top layer becomes one of the most coveted parts of the finished dish.

Step 8: Allow proper rest time before serving

Remove the finished casserole from the oven and place it on a heat-safe surface. Resist the temptation to serve immediately – allow the casserole to rest for 10-15 minutes before cutting into it. This resting period serves several important purposes: it allows the sauce to thicken slightly as it cools, making serving neater; it lets the flavors settle and meld together; and it brings the temperature down from scalding to pleasantly hot for eating. During this time, the residual heat continues to work its magic, integrating all the flavors while maintaining the perfect serving temperature. This brief patience yields a casserole that holds its shape when served rather than spreading across the plate.

A Weeknight Dinner Champion

This Ground Beef and Potato Bake has saved countless evenings in my household when time was short but hunger was high. Unlike many quick dinner solutions that feel like compromises, this casserole delivers real satisfaction with minimal effort. The combination of protein, starch, and creamy sauce creates a complete meal in a single dish.

What makes this recipe particularly valuable is its flexibility around busy schedules. I've assembled it in the morning before work, refrigerated it covered all day, and simply popped it in the oven when I got home. The 75-minute baking time provides the perfect opportunity to help with homework, throw in a load of laundry, or simply enjoy a moment of calm before dinner.

Another time-saving aspect I've come to appreciate is how this dish reheats beautifully for lunches throughout the week. I often intentionally make a larger batch than needed for dinner, knowing the flavors actually improve overnight as they meld together. Individual portions heated in the microwave provide comfort and sustenance during busy workdays when a sandwich just won't cut it.

The Ultimate Blank Canvas

One of the qualities I most appreciate about this potato and beef casserole is its versatility as a base recipe that welcomes adaptation. Over the years, I've created countless variations based on what's in my pantry or garden, and each version has its own unique charm.

During summer months when my herb garden flourishes, I often add a handful of freshly chopped thyme or rosemary to the sauce, transforming the flavor profile with minimal effort. The aromatic herbs infuse the creamy sauce during baking, elevating the dish from simple comfort food to something that feels more sophisticated.

For my spice-loving teenagers, I sometimes brown the beef with taco seasoning and substitute cheddar-jack cheese for standard cheddar, creating a Mexican-inspired version they request repeatedly. A dollop of sour cream and some sliced green onions on top complete the Southwestern transformation.

When serving this to my vegetable-averse nephew, I've been known to sneak finely diced carrots and celery into the sauce, where they cook down until tender and virtually undetectable. The added vegetables boost the nutritional content while maintaining the comfort food appeal that makes this dish so beloved.

During a particularly memorable holiday gathering, I learned a valuable lesson about this recipe's capacity to bring comfort beyond just satisfying hunger. My normally jovial father was unusually quiet following a difficult health diagnosis earlier that week. When I served this casserole – his childhood favorite – I watched as the familiar aroma and taste transported him to happier times. Without saying a word, he took a second helping and finally smiled for the first time that day. Food memories run deep, and this simple casserole has the power to nourish both body and spirit during challenging times.

Family-Friendly Adaptations

The beauty of this Ground Beef and Potato Bake lies in its adaptability to different family preferences and dietary needs. When cooking for my daughter's lactose-sensitive friend, I discovered that dairy-free cream soup alternatives and plant-based milk work surprisingly well in maintaining the creamy texture while eliminating dairy discomfort. The dish retained its comfort food status without causing digestive distress.

For busy sports seasons when we need extra protein for growing athletes, I sometimes add a layer of scrambled eggs between the potato and beef layers. This protein boost transforms the casserole into a substantial meal that sustains energy levels through evening practices and games. The eggs blend seamlessly with the creamy sauce, enhancing both nutrition and flavor.

When we're craving more color and vegetables, a layer of lightly steamed broccoli florets or fresh spinach adds vibrant green between the layers of potato and beef. These additions brighten both the appearance and nutritional profile of the dish without compromising its fundamental comfort food appeal. Even vegetable skeptics tend to enjoy them when they're enveloped in the creamy sauce and melted cheese.

After years of making this Ground Beef and Potato Bake for family dinners, potlucks, and comfort food cravings, I'm still amazed by how something so simple continues to bring such satisfaction. There's wisdom in these old-fashioned casseroles that efficiently transform humble ingredients into something greater than the sum of their parts. While I enjoy experimenting with new recipes and techniques, I've come to believe that true cooking mastery isn't just about creating elaborate dishes – it's about knowing how to nourish people in body and spirit with whatever ingredients you have on hand. This unpretentious casserole does exactly that, which is why it will always have a place in my cooking repertoire.
