• (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 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

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 (and breadcrumbs if using).

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!
