Cheesy Ground Beef and Potato Casserole

Step 5: Add the Cheese

Sprinkle the shredded cheddar and Monterey Jack or mozzarella evenly over the top.

For an especially cheesy finish, reserve a small handful of cheese to add during the final few minutes of baking. This helps create a fresh, gooey layer without over-browning the cheese.

Step 6: Cover and Bake

Cover the baking dish tightly with aluminum foil.

Place it in the preheated 375°F oven and bake for approximately 45 minutes.

The foil is important during this stage because it traps steam inside the dish, helping the potatoes cook until tender instead of drying out.

After 45 minutes, carefully remove the foil.

Step 7: Finish Baking Until Golden

Return the uncovered casserole to the oven and continue baking for another 15–25 minutes, or until the potatoes are completely tender and the cheese is melted, bubbling, and lightly golden around the edges.

To test the potatoes, insert a thin knife into the center of the casserole. It should slide through the potato slices easily.

If the potatoes need additional time but the cheese is already becoming quite brown, loosely cover the dish again with foil and continue baking until the potatoes are tender.

Step 8: Let It Rest

Once the casserole is finished, remove it from the oven and let it rest for about 10 minutes before serving.

This short resting period allows the creamy sauce to settle and makes the casserole easier to portion. Cutting into it immediately can cause the layers to be much more loose and saucy.

Before serving, sprinkle the top with chopped fresh parsley if desired.

Helpful Tips for the Best Results

Slice the potatoes thinly

Thin, evenly sliced potatoes cook more reliably than thick chunks. If you’re worried about the potatoes taking too long, aim closer to ⅛ inch.

Don’t skip covering the casserole

The covered baking stage creates steam, which is especially helpful for cooking the potato layers all the way through.

Season every major component

Because potatoes are naturally mild, seasoning the beef alone isn’t always enough. Lightly seasoning the potato layers gives the entire casserole much more flavor.

Use freshly shredded cheese

Freshly shredded cheese generally melts smoothly and gives the casserole that attractive stretchy, gooey topping.

Give it time to rest

Those extra 10 minutes may seem insignificant, but they make a noticeable difference when you’re serving the casserole.

Easy Variations

Add vegetables:
Sauté diced bell peppers, mushrooms, zucchini, peas, or corn with the onions before adding the beef.

Make it extra cheesy:
Add another ½ cup of shredded cheese between the layers instead of putting all the cheese on top.

Try different cheese:
Colby Jack, pepper Jack, mozzarella, or a cheddar blend can all work beautifully.

Add a little heat:
For a spicier casserole, add a pinch of crushed red pepper flakes or use pepper Jack cheese.

Use a different creamy base:
Cream of chicken or cream of celery soup can replace the cream of mushroom soup if preferred.

What to Serve With It

Because this casserole is already hearty, simple sides work best. A crisp green salad, steamed broccoli, roasted green beans, or lightly seasoned carrots can add freshness to the meal.

For a cozy family dinner, you could also serve it with warm dinner rolls or crusty bread for scooping up the creamy sauce.

Storing and Reheating Leftovers

Allow leftovers to cool before transferring them to an airtight container. Refrigerate for up to 3–4 days.

For the best texture, reheat individual portions in the microwave until heated through. You can also reheat larger portions in a covered oven-safe dish at around 350°F (175°C) until hot.

If the casserole seems slightly dry after refrigeration, adding a small spoonful of milk or a little extra shredded cheese before reheating can help restore some of its creaminess.
