Ingredients You’ll Need
(9×13-inch baking dish; serves 6)
1½ lbs (680g) ground beef
2 cups sliced fresh mushrooms (cremini or white button)
1 (10.75 oz) can condensed cream of mushroom soup
1 (8 oz) can tomato sauce
1 cup shredded cheddar or mozzarella cheese
½ cup chopped onion (optional but recommended)
Salt & black pepper to taste
Optional: 1 tsp garlic powder, ½ tsp dried thyme, or ¼ cup breadcrumbs for topping
💡 Pro Tips:
Sauté mushrooms first—they release water; cooking them dry (no oil) helps them brown and concentrate flavor.
Drain beef well—excess fat makes casserole greasy.
Use full-fat soup—low-fat versions may separate.
Step-by-Step Instructions (Savory, Cheesy, Foolproof)
1. Brown the Beef & Mushrooms
In a skillet over medium heat, cook ground beef until browned; drain fat.
Add mushrooms and onion; cook 5–7 minutes until mushrooms are tender and liquid evaporates.
Stir in cream of mushroom soup and tomato sauce; simmer 3 minutes. Season with salt, pepper, and optional herbs.
2. Layer the Bake
Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Spread beef-mushroom mixture evenly in the dish.
Top with shredded cheese.
3. Bake to Perfection
Bake 25–30 minutes, until bubbly and cheese is golden at the edges.
Optional: Broil 1–2 minutes for extra browning (watch closely!).
4. Rest & Serve
Let sit 5 minutes—allows sauce to thicken slightly.
Serve hot in bowls—comfort in every spoonful!
