What You’ll Need
This recipe calls for simple, readily available ingredients that you probably already have in your pantry. Let’s get started with the shopping list:
- 1.5 lbs Beef Stew Meat: Cubed beef stew meat provides the perfect tender and flavorful base for this dish. Choose a lean cut for a healthier option.
- 1 lb Mushrooms: Cremini or button mushrooms work perfectly, but feel free to experiment with shiitake or oyster mushrooms for a more intense earthy flavor.
- 1 medium Onion: Finely chopped yellow onion adds sweetness and depth to the overall flavor profile.
- 2 cloves Garlic: Freshly minced garlic adds a pungent, aromatic punch that elevates the entire dish. Don’t skip this!
- 2 cups Long-grain Rice: Long-grain rice holds its shape well and absorbs the creamy sauce beautifully.
- 4 cups Beef Broth: Provides the liquid base for the rice and enhances the beefy flavor.
- 1 cup Heavy Cream: The star ingredient! Heavy cream adds incredible richness and creaminess to the sauce.
- 1/2 cup Shredded Cheddar Cheese: Sharp cheddar adds a salty, tangy counterpoint to the richness of the cream.
- 2 tbsp All-Purpose Flour: This helps to thicken the sauce beautifully.
- 1 tbsp Olive Oil: For sautéing the onions and mushrooms.
- 1 tsp Dried Thyme: Adds a lovely herbal note. Fresh thyme is even better if you have it!
- Salt and Pepper: To taste, of course!
Step-by-Step Instructions
Let’s get cooking! This recipe is easier than you think. Follow these steps for a perfect Creamy Beef & Mushroom Rice Bake:
- Prep the Beef: Season the beef cubes generously with salt and pepper. Tip: Pat the beef dry with paper towels before seasoning to ensure even browning.
- Brown the Beef: Heat the olive oil in a large oven-safe skillet or Dutch oven over medium-high heat. Brown the beef cubes in batches, ensuring not to overcrowd the pan. This step develops a rich flavor. Tip: Don’t overcrowd the pan or the beef will steam instead of brown. Work in batches for best results.
- Sauté Aromatics: Once the beef is browned, remove it from the pan and set aside. Add the chopped onion to the pan and sauté until softened, about 5 minutes. Add the minced garlic and sauté for another minute until fragrant. Tip: Don’t burn the garlic! Low to medium heat is best for this step.
- Cook the Mushrooms: Add the mushrooms to the pan and cook until they release their moisture and brown slightly, about 5-7 minutes. Tip: Season the mushrooms with a pinch of salt and pepper while they cook to enhance their flavor.
- Make the Sauce: Sprinkle the flour over the mushrooms and onions, stirring constantly for 1 minute to create a roux. Gradually whisk in the beef broth, ensuring no lumps form. Bring the mixture to a simmer.
- Combine and Simmer: Return the browned beef to the pan. Stir in the thyme and heavy cream. Bring the mixture to a simmer, then reduce the heat to low, cover, and simmer for 15-20 minutes, or until the beef is tender. Tip: Taste and adjust seasoning as needed.
- Add Rice: Stir in the rice and ensure it’s evenly distributed throughout the sauce. Tip: Use long-grain rice for best results.
- Bake: Sprinkle the shredded cheddar cheese over the top. Transfer the skillet to a preheated oven at 375°F (190°C) and bake for 20-25 minutes, or until the cheese is melted and bubbly, and the rice is cooked through.Tip: Keep an eye on it to prevent burning.
- Serve: Let the casserole rest for 5-10 minutes before serving. Enjoy!
Tips for Success
To ensure your Creamy Beef & Mushroom Rice Bake turns out perfectly, here are a few helpful tips: Don’t overcrowd the pan when browning the beef; this ensures even browning and prevents steaming. Use fresh, high-quality ingredients for the best flavor. Make sure the beef broth is simmering gently, to prevent the sauce from becoming too thick. Don’t overcook the rice; it should be tender but not mushy. Allow the casserole to rest for a few minutes after baking before serving; this allows the flavors to meld and the cheese to set.
Variations to Try
Feel free to customize this recipe to your liking! Add a splash of Worcestershire sauce for extra umami depth. Substitute other cheeses like Gruyère or Monterey Jack for a different flavor profile. For a vegetarian version, swap the beef for 1 lb of firm tofu, cubed and browned in the pan. For a spicier kick, add a pinch of red pepper flakes or a dash of your favorite hot sauce. To make it gluten-free, ensure your broth and other ingredients are gluten-free.

Storing and Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions until heated through, or gently reheat in a skillet over low heat. Freezing is also possible; allow the casserole to cool completely, then transfer it to a freezer-safe container and freeze for up to 2 months. To reheat from frozen, thaw overnight in the refrigerator and then reheat as directed above. For best results when reheating, add a splash of milk or cream to prevent it from drying out.
