Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 lb ground beef
8 oz mushrooms, sliced
1 small onion, diced
2 cloves garlic, minced
1 can (10.5 oz) cream of mushroom soup
½ cup sour cream
½ tsp paprika
½ tsp thyme (optional)
Salt and pepper to taste
1 cup shredded mozzarella or cheddar cheese
Optional for serving: cooked egg noodles, rice, or cauliflower rice

Directions

Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

In a large skillet over medium heat, cook the ground beef and diced onion until browned and no longer pink, about 6–8 minutes. Drain any excess fat.
Add the minced garlic and sliced mushrooms to the skillet. Cook for another 5–6 minutes until the mushrooms are softened and fragrant.
Stir in the cream of mushroom soup, sour cream, paprika, thyme (if using), salt, and pepper. Mix until everything is evenly coated in the creamy sauce.
Transfer the mixture into the prepared baking dish and spread it out evenly. Sprinkle the shredded cheese on top.
Bake uncovered for 25–30 minutes, until the cheese is melted and the casserole is hot and bubbly.
Serve over cooked noodles, rice, or enjoy on its own for a low-carb, comforting meal.

Variations

Add Veggies: I sometimes stir in frozen peas or chopped spinach for added color and nutrition.
Spicy Kick: A pinch of chili flakes or a dash of hot sauce adds a nice heat.
Switch the Cheese: Trying Gruyère, Monterey Jack, or a cheddar blend gives different flavors.
Meat Options: Ground turkey or chicken also work well in place of beef.

Storage/Reheating

To store leftovers, I let the casserole cool completely, then cover it tightly and refrigerate for up to 4 days. For reheating, I use the microwave or oven until it’s heated through. If it seems dry, I add a splash of milk or broth to bring back the creaminess.
