Creamy Beef Mushroom Rice Bake

Featured in Satisfying Main Courses.

This creamy beef and mushroom rice bake combines browned ground beef, chopped mushrooms, and tender onions with uncooked white rice in a savory blend of cream of mushroom soup, beef broth, and sour cream. The whole dish comes together in the oven, where it bakes gently until the rice is soft and all ingredients are infused with rich, comforting flavors. A sprinkle of cheddar cheese on top, if you wish, finishes the bake with a golden, melty layer. After resting out of the oven, each slice is hearty and packed with creamy goodness—perfect for weeknight family meals or make-ahead gatherings.

There are nights when all I want is comfort in a single dish and this creamy beef and mushroom rice bake delivers every time The beef gets browned and savory mushrooms add a real earthy note while the rich sauce soaks into the fluffy rice Weeknight dinners do not get easier than this and the best part is you can prep it all in one casserole dish for simple cleanup

When I first made this I was juggling a toddler and a teething baby so anything that could go in the oven and bake itself was a lifesaver Now it is a dish my oldest requests when he comes home from college and we sit around the table talking about old times

Ingredients

  • Ground beef: Look for ninety three percent lean for less grease and easy browning It brings hearty protein and rich flavor
  • Chopped mushrooms: Fresh mushrooms add earthiness and moisture I pick cremini or white button and always wipe any dirt away before chopping
  • Small onion diced: Fresh onion brings sweetness and foundation to the flavor Choose a firm onion with tight skin for best results
  • Uncooked white rice: Regular long grain white rice gives this dish its signature fluffy texture Rinse before using to remove extra starch
  • Cream of mushroom soup: This creates instant creaminess throughout the bake Low sodium cans let you control the seasoning
  • Beef broth: Use a good quality broth for depth A boxed broth or homemade will really shine here
  • Sour cream: Adds a tangy creamy richness Full fat works best for a luscious sauce
  • Garlic powder: Gives cozy background flavor Make sure your garlic powder is fresh and fragrant
  • Salt and pepper to taste: Always taste and adjust seasoning as you go to balance the flavors
  • Shredded cheddar cheese optional: For a bubbly golden topping Pick sharp cheddar with bold flavor and grate it yourself for best melt

Step-by-Step Instructions

Brown the Beef and Aromatics:
In a large skillet cook ground beef mushrooms and onion over medium heat Stir often to break up the beef and let the onions get soft Cook for about ten minutes until beef is no longer pink Use a spoon to drain off excess fat for a less greasy casserole
Mix the Base:
In a big mixing bowl combine your browned beef mixture uncooked white rice cream of mushroom soup beef broth sour cream garlic powder a good pinch of salt and some black pepper Stir everything together until it is fully blended and the rice is evenly mixed in
Layer and Bake:
Spread the whole mixture into a greased nine by thirteen inch baking dish Use a spatula to smooth the top so it cooks evenly Cover tightly with foil This creates steam for tender rice Bake at three hundred fifty degrees Fahrenheit for fifty to sixty minutes until the rice is soft and the liquid is mostly absorbed
Finish with Cheese:
If using cheddar cheese sprinkle over the top of the casserole after baking Remove foil and bake uncovered for five more minutes until the cheese melts and bubbles Let it stand at least three minutes so the sauce thickens before serving

Mushrooms are my secret weapon in this bake Their moisture keeps every bite tender and that hint of earthiness makes the flavor feel so much richer My family always jokes that they wish there was a way to bottle the smell of this rice bake in the oven because it means everyone comes running to the table

Storage Tips

Wrap leftovers tightly or keep them in an airtight container in the fridge They will taste just as good for two to three days To reheat add a splash of beef broth to keep the rice nice and creamy Warm in the oven covered with foil or microwave individual portions

Ingredient Substitutions

If you are out of ground beef you can use ground turkey or chicken Just know turkey brings a lighter flavor Swap white rice for brown for a more wholesome touch but tack on an extra fifteen to twenty minutes baking time No sour cream No problem Greek yogurt works and gives a bright tang

Serving Suggestions

This dish is hardy enough to be a meal on its own but it also pairs well with steamed green beans or a crisp salad For an extra pop toss some fresh parsley on before serving and it will look like it came out of a fancy kitchen Leftovers get even better and can be scooped into tortillas for a fun lunch
