Ingredients You'll Need

Ground Beef- The main protein in the casserole. Ground beef gives the dish that rich savory cheesesteak flavor while keeping it easy and budget-friendly.
Bell Peppers- A classic cheesesteak ingredient. They add sweetness, color, and a tender bite that works perfectly with the beef and cheese.
Onion- Adds savory depth and a little sweetness as it cooks down. Onion is essential for that classic cheesesteak-style flavor.
Cream Cheese- Helps make the casserole creamy and rich while also helping the filling hold together.
Beef Broth- Adds extra savory depth and keeps the casserole from feeling dry.
Worcestershire Sauce- Brings a deep meaty flavor that enhances the ground beef beautifully.
Garlic- Adds bold savory flavor and helps build the overall richness of the casserole.
Italian Seasoning- Adds just a little herbal depth and rounds out the dish.
Salt- Enhances all the other flavors and helps the beef and vegetables taste well-seasoned.
Black Pepper- Adds a little warmth and bite.
Provolone Cheese- A classic cheesesteak cheese with great melt and mild savory flavor.
Mozzarella Cheese- Adds extra melty stretch and richness to the top of the casserole.
Butter or Olive Oil- Used to cook the vegetables and help develop flavor at the beginning of the recipe.

Cook the Vegetables. Heat butter or oil in a skillet and cook the peppers and onions until they are softened and lightly golden. This gives them that sweet savory flavor that makes cheesesteaks so good.

Brown the Ground Beef. Add the ground beef to the skillet and cook until browned, breaking it up as it cooks. Drain any excess grease if needed. Stir in the garlic, Worcestershire sauce, beef broth, Italian seasoning, salt, and black pepper. Let everything simmer briefly so the flavors blend together.

Make It Creamy. Add the cream cheese and stir until it melts into the beef mixture and creates a creamy rich filling. **Optional** If not using an oven-safe skillet, spread the mixture into a casserole dish in an even layer.

How Long Does It Last?

Cooked low carb ground beef cheesesteak casserole can be stored in an airtight container in the refrigerator for up to 4 days. It reheats very well, which makes it excellent for meal prep.

Provolone is classic, but mozzarella, Monterey Jack, or white American-style cheese also work well.
