Ingredients You’ll Need

(9x13-inch baking dish)

1½ lbs (680g) ground beef
1 (10.75 oz) can condensed cream of mushroom soup
1 (8 oz) package sliced fresh mushrooms (or 1 cup drained canned mushrooms)
1½ cups shredded cheddar or Swiss cheese
- Plus: ¼ cup water or milk (commonly included in “4-ingredient” home cooking for moisture)

Fresh mushrooms add depth, but canned work in a pinch.

Step-by-Step Instructions (Creamy, Savory, Foolproof)

1. Prep & Preheat

Preheat oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.

2. Brown the Beef (Optional but Recommended)

In a skillet, cook ground beef over medium heat until browned; drain excess fat.
Shortcut: Add raw beef directly to baking dish—just extend bake time by 5–10 minutes.

3. Assemble the Bake

In the baking dish, combine beef, mushrooms, cream of mushroom soup, and water/milk.
Stir gently to mix.
Sprinkle shredded cheese evenly over the top—do not stir.
