Ingredients You’ll Need

One of my favorite things about this Cheesy Mushroom and Beef Rice Bake Recipe is how it transforms simple pantry staples into something truly special. Each ingredient plays a big role in building layers of flavor, making the casserole creamy, savory, and oh-so-satisfying.

• Ground beef (1 lb., 85% lean): Brings hearty flavor and richness—choose a blend with some fat for the juiciest result.
• Italian seasoning (1.5 tsp): This small addition lifts everything with herbal brightness.
• Salt and pepper: Essential for bringing out the best in every ingredient—season as you go!
• Butter (3 tbsp, divided): Melted butter makes the onions and rice luscious and fragrant.
• Onions (¾ cup, diced): They add a subtle sweetness and extra depth of flavor.
• Garlic (1 tbsp, minced): Quick sautéing transforms garlic into a savory backbone for the casserole.
• Beef broth (2½ cups): Cooking the rice in broth adds a meaty, savory dimension that water just can’t match.
• Uncooked long-grain white rice (1¼ cups, not instant): Absorbs all the delicious liquid and bakes up fluffy and satisfying.
• Button mushrooms (8 oz., sliced): They soak up all the savory flavors and add a lovely, earthy bite.
• Cream of mushroom soup (10.5 oz. can): Doubles down on the mushroomy goodness and creates that beloved creamy texture.
• Milk (½ cup, any kind): Makes the sauce perfectly pourable and creamy without being too heavy.
• Sour cream (½ cup): Adds a welcome tang that brightens up all that cheese and beef.
• Cheddar cheese (2 cups, divided): Half melts into the casserole, and the rest bubbles up into a golden, gooey topping.

Variations

This Cheesy Mushroom and Beef Rice Bake Recipe is a blank canvas for your weeknight dreams! It’s endlessly adaptable, so feel free to make it your own depending on what’s in the fridge or your family’s favorite flavors.

• Chicken Swap: Substitute ground chicken or turkey in place of beef if you’d like a lighter bite.
• Veggie Add-Ins: Stir in frozen peas, corn, or chopped spinach when adding the beef back in for more color and nutrients.
• Dairy-Free: Use your favorite plant-based cheese and sour cream alternatives for a lactose-free version.
• Cheese Lovers: Try a blend of sharp cheddar, Monterey Jack, or even a sprinkle of mozzarella on top for extra melty goodness.
• Spice It Up: Add a pinch of red pepper flakes, a diced jalapeño, or a few dashes of hot sauce to the beef for kick!

How to Make Cheesy Mushroom and Beef Rice Bake Recipe

Step 1: Brown the Beef

Start by preheating your oven to 350°F. In a large, heavy-bottomed pot, cook your ground beef over medium-high heat, breaking it up as you go. Sprinkle in the Italian seasoning, salt, and pepper while it browns. Drain off any grease, then transfer the cooked beef to a plate and keep it covered so it stays warm—this lets the flavors settle in nicely and your pan is ready for the next step.

Step 2: Sauté the Onions and Garlic

Using the same pot (no need to wash—a bit of beefy residue only adds flavor!), melt 2 tablespoons of butter over medium heat. Toss in the diced onions and cook for about 5 minutes until they’re soft and fragrant. Add the garlic and let it sizzle for just another minute—trust me, your kitchen will smell incredible.

Step 3: Cook the Rice and Mushrooms

Pour in the beef broth and remaining tablespoon of butter, then stir in your uncooked rice. Give everything a good mix, bring it to a boil, then reduce heat to low and cover tightly. Let the rice simmer for 10 minutes, then carefully add the sliced mushrooms. Replace the lid and cook for 5-10 more minutes (check your rice package for precise timing). Hands off: don’t stir! Just let everything steam and mingle together.

Step 4: Let It Rest

Once the rice is tender and the mushrooms are soft, turn off the heat and keep the lid on for another 10 minutes. This restful pause is the secret to fluffy, perfectly cooked rice that won’t stick to the bottom.

Step 5: Mix in the Creamy Goodness

Add the ground beef back to the pot along with the cream of mushroom soup, milk, sour cream, and half of your shredded cheddar. Stir until everything is beautifully combined—the cheese should melt right in, keeping things creamy and cohesive.

Step 6: Assemble and Bake

Spread your casserole mixture into a lightly greased 9×13-inch baking dish. Sprinkle the remaining cheddar cheese on top (the more, the merrier!). Cover with foil and bake for about 20 minutes, until everything is melty and bubbly. Then, let it stand for a few more minutes—it makes serving easier and deepens the flavors that much more.

How to Serve Cheesy Mushroom and Beef Rice Bake Recipe

Garnishes

Just before serving, sprinkle the top with a shower of freshly chopped parsley or green onions for a burst of color and freshness. A light dusting of extra black pepper or even a little dash of smoked paprika can also take the visual appeal—and flavor—up a notch!

Side Dishes

This Cheesy Mushroom and Beef Rice Bake Recipe pairs beautifully with simple, crisp side salads or steamed green beans. For a little something extra, serve with warm crusty bread to soak up every last bit of cheesy sauce.

Creative Ways to Present

For individual servings, scoop into ramekins and finish under the broiler until bubbling for a bistro-inspired touch. Or serve straight from the baking dish for a classic, family-style presentation that encourages everyone to dig in together.

Make Ahead and Storage

Storing Leftovers

Leftovers are pure gold with this recipe! Let the casserole cool completely before transferring to an airtight container. Kept in the fridge, it will stay fresh and delicious for up to 3 days.

Freezing

The Cheesy Mushroom and Beef Rice Bake Recipe freezes remarkably well. Wrap individual portions or the whole (cooled) casserole tightly in foil and freeze for up to two months. Thaw overnight in the fridge for best results.

Reheating

For the creamiest texture, reheat in a covered oven-safe dish at 325°F until hot and bubbly, about 20-25 minutes. If you’re in a hurry, microwave individual portions, adding a splash of milk to keep things moist.
