There is something about coming home to the aroma of melting cheese and savory steak after a long day. This slow cooker steak and cheddar potato casserole is pure comfort for anyone needing a hearty, filling meal without spending hours in the kitchen. Everything melds together into layers of tender potatoes, juicy steak, and gooey cheddar, making it a dish that will warm you from the inside out.
I always make this for family get-togethers because everyone ends up going back for seconds. The first time I served it, my youngest declared it was better than restaurant food and asked for leftovers in his lunch.
Ingredients
- Sirloin or ribeye steak cubes: Provide rich flavor and tender texture Use well marbled meat for best results
- Russet or Yukon Gold potatoes: Give a creamy bite that holds up to slow cooking Yukon Golds are especially buttery
- Sharp cheddar cheese: Freshly grated melts smoother and has a bolder taste than pre-shredded Look for orange or white aged cheddar
- Heavy cream: Brings richness and helps the cheese sauce blend perfectly Always choose a cream with a fresh smell
- Beef broth: Deepens meaty flavors Use low sodium for more control over seasoning
- Onion: Finely diced for sweetness and depth Choose a firm onion with papery skin
- Garlic: Brightens the overall dish with savory notes Use fresh for the best aroma
- Butter: Helps brown the steak and adds a comforting richness Unsalted is ideal
- Smoked paprika: Lends a smoky complexity and great color Spanish varieties have the best flavor
- Black pepper: Lifts all the flavors with a gentle heat Use freshly ground
- Salt: Essential for balancing all the ingredients Kosher salt is easiest to sprinkle evenly
Step-by-Step Instructions
- Sear the Steak:
- Start by melting butter in a skillet over medium-high heat Add the steak cubes seasoned with salt black pepper and smoked paprika Brown the pieces on all sides for about five minutes until a rich crust forms on each piece Browning the steak gives depth to the whole casserole
- Layer in the Slow Cooker:
- Arrange half of the potato slices in your slow cooker Lay them in overlapping shingle patterns for even cooking Next scatter half the diced onion and half the garlic on top Place all the browned steak across the layer Then finish with the rest of the potatoes followed by the remaining onion and garlic These layers make sure every bite is flavorful
- Pour and Season:
- Slowly drizzle the beef broth and heavy cream evenly over all the layers Add an extra pinch of salt and pepper if you like more seasoning This step is key for a creamy and well-seasoned base
- Top with Cheese:
- Sprinkle the freshly grated cheddar cheese evenly on top The cheese melts into a luscious and slightly crispy crust
- Cook Low and Slow:
- Cover the slow cooker and cook for six to eight hours on low or three to four hours on high The potatoes should be fork tender and the cheese golden at the edges Let it rest for ten minutes after cooking so the sauce thickens

I love using smoked paprika here because it reminds me of my grandmother’s old kitchen Whenever she cooked steak she insisted on adding just a pinch of smoky spice and it makes all the difference Every bite brings back the best memories of Sunday dinners
Storage Tips
This casserole stores well in an airtight container in the fridge for up to three days Let it cool at room temperature before sealing to prevent condensation If you want to freeze it portion into individual servings so you can reheat just what you need It is best reheated in the oven covered with foil to keep it moist
Ingredient Substitutions
If you are out of sirloin or ribeye try chuck steak or even stew beef for a more budget-friendly option Swap in Monterey Jack for part of the cheddar for a melty twist Want to lighten it up Use half and half instead of heavy cream and low fat cheese Go for sweet potatoes instead of Yukon Golds to add more color and subtle sweetness

Serving Suggestions
This casserole holds its own as a main dish but pairs beautifully with a tangy green salad or some roasted Brussels sprouts For extra decadence garnish with chives or a spoonful of sour cream on top Toasted bread or crusty rolls turn it into a complete comfort meal
