- 1 ¼ cups uncooked long-grain rice
- 2 ½ cups beef broth

Step-by-Step Instructions
Start by heating a large skillet over medium-high heat. Add the ground beef and break it apart as it cooks, letting it brown and caramelize for deeper flavor. Once the beef is partially cooked, stir in the onions and mushrooms.
Let them sauté with the beef until the onions turn soft and translucent and the mushrooms release their juices and turn golden. Add garlic and cook for one minute until fragrant. Season with Worcestershire sauce, salt, pepper, onion powder, and garlic powder, blending the flavors into the mixture. Remove from heat and set aside.
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Pour the uncooked rice evenly into the dish, creating a level base. In a mixing bowl, combine the cream of mushroom soup, beef broth, milk or cream, smoked paprika, and dried thyme.
Whisk until everything is smooth and fully blended. Pour this creamy mixture over the rice, then give it a light stir to distribute the liquid evenly among the grains.
Spoon the beef and mushroom mixture evenly across the top of the rice. Gently press it down so it settles into the creamy sauce but remains distributed throughout the dish.
Cover tightly with foil, ensuring it’s sealed well along the edges to keep steam inside while baking. Bake for 50–55 minutes or until the rice is tender and most of the liquid is absorbed. Carefully remove the foil and test a few grains of rice to ensure they are soft and fully cooked.
Once the rice is done, sprinkle mozzarella and optional cheddar evenly across the top of the casserole. Return it to the oven uncovered for 10–12 minutes or until the cheese is melted, bubbly, and lightly golden.
Remove from the oven and let the dish rest for at least 10 minutes before serving. This rest period helps the creamy sauce settle, allowing the rice to absorb any remaining liquid. Garnish with fresh parsley or thyme and serve warm straight from the baking dish.
Expert Tips for Success
Use long-grain rice to ensure a fluffy, tender bake that holds its structure well. Avoid instant rice, which cooks too quickly and becomes mushy in casseroles.
Browning the beef thoroughly enhances the flavor and prevents excess grease from watering down the sauce. If your beef is particularly fatty, drain a small amount but leave enough for rich flavor. Sautéing mushrooms until golden boosts their savory depth and reduces excess moisture.
Whisking the creamy mixture thoroughly ensures even distribution throughout the rice, preventing pockets of dryness. Covering the dish tightly is essential—steam is what cooks the rice perfectly. If your oven runs hot, check the dish around the 45-minute mark.
After adding cheese, broil for one minute if you want a crispier, more bubbly topping. Letting the casserole rest before serving prevents excess moisture and allows flavors to meld beautifully.
Variations and Substitutions
Add sliced mushrooms of different varieties—cremini, baby bella, or shiitake—to deepen the earthiness and add texture. Replace ground beef with ground turkey or chicken for a lighter version.
A creamier profile can be achieved by stirring in a dollop of sour cream or softened cream cheese into the sauce before pouring it over the rice. Add frozen peas, green beans, or carrots for extra vegetables and color.
For a richer, French-inspired twist, deglaze the skillet with a splash of white wine before adding the mushroom soup mixture. Add herbs like rosemary or sage for a more aromatic blend.
Swap mozzarella for Swiss or Gruyère for a nuttier, more decadent flavor. If you enjoy spice, stir in crushed red pepper flakes or diced jalapeños. Adding caramelized onions creates a sweeter, deeper flavor that pairs beautifully with beef.
Serving Suggestions and Pairings
Serve this casserole with a simple green salad tossed in vinaigrette to balance the richness of the dish. Garlic bread or warm dinner rolls make excellent accompaniments, perfect for scooping up any creamy sauce left behind.
A side of roasted broccoli or green beans pairs wonderfully and adds color and freshness to the plate. For a heartier meal, serve alongside buttered corn or glazed carrots.
If you’re hosting a cozy dinner, pair the casserole with a comforting soup like creamy tomato or vegetable chowder. For a lighter meal, serve small portions with crisp cucumbers or sliced tomatoes on the side.
This dish also pairs well with iced tea, lemonade, or earthy red wines like merlot or cabernet. Featuring it at potlucks is always a success—its comforting flavors make it universally appealing and satisfying.
Storage, Freezing, and Reheating
Store leftovers in an airtight container in the refrigerator for up to four days. The flavors deepen as it rests, and reheated portions taste even more delicious. Reheat gently in the microwave or in a 350°F oven until warm. Add a splash of broth or milk if the rice thickens too much. Avoid reheating too quickly, which can dry out the dish.
To freeze, portion the casserole into freezer-safe containers and store for up to two months. Thaw overnight in the refrigerator before reheating for best texture.
If freezing the entire dish, wrap tightly in foil and plastic wrap. Reheat in the oven covered with foil until warmed through. Adding a small handful of fresh cheese before reheating restores creaminess and enhances flavor.
