Step 5: Add the Creamy Sauce

Spread the cream of mushroom soup over the beef and pepper mixture.

Stir everything together until the sauce coats the ingredients evenly.

The creamy soup acts as a binder, creating a rich sauce that brings the entire casserole together.

If the mixture looks too thick, you can add a few tablespoons of milk to loosen it slightly.

Step 6: Add the Cheese Layer

Sprinkle shredded cheddar cheese evenly over the top.

The cheese will melt during baking and create a golden, bubbly crust.

For extra flavor, you can mix cheddar with:

• Monterey Jack
• Mozzarella
• Colby cheese

Step 7: Bake the Casserole

Place the baking dish in the preheated oven.

Bake uncovered for:

25–30 minutes

The bake is ready when:

• The cheese is melted and golden.
• The edges are bubbling.
• The peppers are tender.

For a darker cheese topping, place it under the broiler for 1–2 minutes at the end, watching carefully to avoid burning.

Step 8: Rest Before Serving

Remove the casserole from the oven and let it rest for:

5–10 minutes

This allows the sauce to thicken slightly and makes serving easier.

Cut into portions and serve warm.
