Creamy Beef Mushroom Rice Bake

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.

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
