Why You Will Love This Easy Ground Beef Casserole

This ground beef casserole with cheese uses easy-to-find ingredients and does not require complicated techniques.

Easy Weeknight Dinner

Most of the preparation happens in a single skillet before the recipe goes into the oven.

Plenty of Melted Cheese

Provolone and mozzarella create a soft, melted topping over the beef and vegetables.

Simple Ingredients

The recipe does not depend on hard-to-find ingredients or elaborate sauces.

Easy to Customize

You can add mushrooms, jalapeños, change the cheeses, or even use another type of ground meat.

Great for Leftovers

Leftovers can be stored in the refrigerator and easily reheated for another meal.

Ingredients

For the Beef Mixture

• 680 g ground beef

• 1 tablespoon olive oil

• 1 medium yellow onion, finely chopped

• 1 green bell pepper, diced

• 1 yellow or orange bell pepper, diced

• 2 garlic cloves, minced

• 1 tablespoon Worcestershire sauce

• 1 teaspoon paprika

• ½ teaspoon garlic powder

• ½ teaspoon onion powder

• ½ teaspoon salt, or to taste

• ¼ teaspoon black pepper

• ½ teaspoon Italian seasoning, optional

• 2 tablespoons cream cheese, optional

For the Cheese Topping

• 1 ½ cups shredded provolone

• 1 cup shredded mozzarella

• ½ cup shredded cheddar, optional

The combination of ground beef, bell peppers, onion, and melted cheese gives this recipe its Philly cheesesteak-inspired flavor.

Provolone works very well because it melts easily and pairs nicely with the flavor of the beef.

Mozzarella makes the topping soft and stretchy, while cheddar can add a more pronounced cheese flavor.

How to Make Low Carb Philly Cheesesteak Casserole

Step 1: Prepare the Vegetables

Start by chopping the onion and bell peppers.

For this easy casserole recipe, I like to cut the vegetables into small pieces. This way, they are well distributed throughout the beef and it is easy to get a little of each ingredient in every bite.

Mince the garlic and keep the seasonings nearby.

This small preparation makes the whole process more organized.

Step 2: Brown the Ground Beef

Heat a large skillet over medium-high heat.

Add the olive oil and ground beef.

Using a wooden spoon or spatula, break the beef into smaller pieces.

Cook for approximately 6–8 minutes, stirring occasionally, until nicely browned and completely cooked.

An important tip is not to stir constantly.

Let the beef stay in contact with the hot skillet for a few moments.

This helps create those small browned pieces that make the ground beef casserole even more flavorful.

If there is a lot of fat in the skillet, carefully remove some of it.

There is no need to remove all of the fat.

Step 3: Add the Onion and Bell Peppers

Add the onion, green bell pepper, and yellow or orange bell pepper to the same skillet.

Mix with the beef.

Cook for approximately 5–7 minutes, stirring a few times.

The onion should become soft and translucent, while the bell peppers should soften without completely losing their texture.

This is when the aromas of the beef, onion, and bell peppers begin to come together.

Do not worry about making every piece the same size.

This is a homemade recipe and it does not need to look perfect.

Step 4: Add the Garlic

Add the minced garlic.

Cook for approximately 30 seconds to 1 minute, stirring constantly.

The goal is simply to make the garlic fragrant.

Avoid letting it become too dark, as it can develop a bitter flavor.

Step 5: Season the Beef and Vegetables

Add the Worcestershire sauce, paprika, garlic powder, onion powder, salt, black pepper, and Italian seasoning, if using.

Mix very well.

Cook for another 1–2 minutes, allowing the seasonings to distribute their flavor throughout the beef and vegetables.

Taste at this point.

If necessary, adjust the salt or pepper before adding the cheese.

This small taste test helps keep the recipe balanced.

Step 6: Add the Cream Cheese

If you want a creamier filling, add the cream cheese.

Stir until it melts into the hot beef and vegetables.

There is no need to use a large amount.

It simply makes the filling a little creamier.

If you prefer a simpler low carb ground beef casserole, you can leave this ingredient out.

The cheese topping already provides plenty of creaminess.

Step 7: Prepare the Baking Dish

Preheat the oven to 190°C.

Lightly grease a baking dish approximately 23 x 33 cm.

Transfer the beef and vegetable mixture to the baking dish.

Spread it evenly.

There is no need to press it down too much.

Simply distribute the filling all the way to the edges.

Step 8: Add the Cheese

Spread the provolone over the entire surface.

Then distribute the mozzarella and cheddar, if using.

Try to cover most of the surface of the casserole.

This way, the cheese melts evenly and creates a generous topping.

Step 9: Bake Until the Cheese Melts

Place the baking dish in the preheated oven.

Bake for approximately 15–20 minutes, or until the cheese is completely melted and bubbling around the edges.

For a lightly browned surface, use the broiler during the final 1–2 minutes.

Watch carefully during this step to prevent the cheese from becoming too dark.

Remove from the oven and let it rest for approximately 5 minutes before serving.

Techniques for an Even Better Casserole

Brown the Beef Well

A large skillet helps the beef brown instead of simply cooking in its own steam.

Avoid putting an excessive amount of beef into a small skillet.

Cook the Vegetables Well

The onion and bell peppers need time to soften.

In addition, cooking helps reduce the excess water released by the vegetables.

Avoid Excess Liquid

Before transferring the filling to the baking dish, check the amount of liquid in the skillet.

If there is too much liquid, continue cooking for a few minutes so it can reduce.

This helps create a more pleasant final texture.

Taste Before Adding the Cheese

Cheese already has its own flavor and salt.

For this reason, taste the beef before adding the topping and make any necessary adjustments.

Let It Rest

Five minutes are enough for the filling to become a little firmer and easier to serve.

How to Prevent a Watery Casserole

A good cheesy casserole should be moist, but not full of liquid.

The onion and bell peppers naturally release water during cooking.

This is not a problem.

The important thing is to allow much of this moisture to evaporate before placing the filling in the oven.

The finished mixture should be moist, but there should not be a large amount of liquid collected in the skillet.

If using mushrooms, pay even more attention, as they also release quite a bit of water.

Cook until most of this liquid has disappeared.

What Is a Philly Cheesesteak Casserole?

Traditional Philly cheesesteak is known for the combination of thinly sliced beef, onion, melted cheese, and bread.

This recipe uses that combination as inspiration, but turns everything into a baked dish.

Here we use ground beef instead of thinly sliced beef.

We also do not use the traditional bread.

The beef and vegetables are cooked together and then topped with cheese before going into the oven.

Therefore, this is a Philly cheesesteak-inspired casserole, not a traditional version of the Philadelphia sandwich.

What to Serve with This Low Carb Recipe

This easy dinner recipe is already quite complete, but some simple side dishes pair very well with it.

Green Salad

A salad of leafy greens, cucumber, tomato, and a simple dressing adds freshness to the meal.

Roasted Broccoli

Roasted broccoli is a practical option to serve with beef and cheese.

Cauliflower Rice

Cauliflower rice is an alternative for anyone looking for low carb side dishes.

Green Beans

Green beans quickly sautéed with garlic are another simple option.

Roasted Zucchini

Slice the zucchini, season it, and place it in the oven while the casserole finishes baking.

Easy Variations

Chicken Philly Cheesesteak Casserole

Replace the ground beef with cooked and chopped chicken.

It is a practical way to use leftover chicken.

Ground Turkey Casserole

Ground turkey can also be used.

Since its flavor is milder, taste the mixture and adjust the seasonings before adding the cheese.

Spicy Version

Add chopped jalapeño, red pepper flakes, or hot sauce.

Pepper jack cheese also pairs very well.

Mushroom Version

Add sliced mushrooms along with the onion and bell peppers.

Cook until most of the released water has evaporated.

Extra Creamy Version

For anyone who loves plenty of cheese, increase the amount of provolone or mozzarella.

You can also add cheddar.

Without Cream Cheese

Cream cheese is optional.

If you prefer, prepare the recipe using only beef, vegetables, and cheese.

How to Prepare Ahead

This recipe can be prepared ahead of time.

Prepare the beef and vegetables according to the instructions.

Place the mixture in the baking dish and let it cool.

Cover and refrigerate.

When ready to cook, add the cheese and bake at 190°C until hot and the cheese is completely melted.

Since the baking dish will be cold, you may need to add a few minutes to the baking time.

Storage

Let the leftovers cool before storing.

Place them in a sealed container and keep them in the refrigerator for up to 3–4 days.

You can also divide the leftovers into individual containers to make upcoming lunches or dinners easier.

How to Reheat

For one serving, heat in the microwave in short intervals until hot.

For several servings, place in an oven-safe baking dish and heat at 175°C until hot.

If the cheese begins to brown too much, loosely cover with aluminum foil.

Avoid heating for too long to prevent the beef from becoming dry.

Can I Freeze This Casserole?

Yes.

Let the casserole cool completely and transfer it to a freezer-safe container.

For the best quality, consume within approximately 2–3 months.

Thaw in the refrigerator overnight before reheating.

If using a glass baking dish, make sure it is freezer-safe and avoid sudden temperature changes.

My Experience Making This Recipe

What I like most about this recipe is the feeling of homemade food.

There is no complicated technique.

I start with the ground beef and let it brown well before stirring too much.

Those browned pieces add plenty of flavor.

Then the onion and bell peppers go into the same skillet.

I prefer to cut the vegetables into smaller pieces because they become better distributed throughout the beef.

The garlic goes in near the end because it needs very little time.

After adding the seasonings, I like to taste the mixture.

This small step helps me notice whether more salt or pepper is needed before adding the cheese.

Then everything goes into the baking dish.

I spread the cheese over the entire surface and let the oven do the rest.

When the casserole comes out bubbling and lightly browned, it is hard to wait to serve it.

Even so, it is worth letting it rest for five minutes.

The filling becomes easier to serve and the cheese remains hot and melted.

A simple green salad creates a fresh contrast.

Broccoli, zucchini, or green beans also pair very well.

If desired, finish with a little chopped fresh parsley.

There is no need to use much.
