Ingredients

This recipe uses simple, accessible ingredients that combine to create a hearty, low-carb casserole.

Meat

• 2 lbs ground beef – Forms the protein base. Use lean ground beef for less fat or regular for richer flavor.

Produce

• 1 large onion, sliced – Provides caramelized flavor and savory depth.
• 2 cloves garlic, minced – Enhances aroma and flavor.

Condiments & Seasoning

• 2 tbsp Worcestershire sauce – Adds umami and complexity.
• Salt and pepper, to taste – Essential for seasoning.

Oils & Dairy

• 1 tbsp olive oil – For sautéing vegetables.
• 8 oz cream cheese – Creates a creamy, cheesy base.
• 1 ½ cups shredded mozzarella cheese – Adds melty, stretchy texture.
• 8 oz provolone cheese, sliced or shredded – Adds a mild, creamy flavor that complements the beef and veggies.

Equipment

• Large skillet or sauté pan
• Cutting board
• Sharp knife
• Measuring cups and spoons
• 9×13-inch baking dish
• Wooden spoon or spatula

Preparation Method

Step 1: Preheat Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or olive oil.

Step 2: Sauté Vegetables

Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the sliced bell peppers and onions, cooking for 5–7 minutes until softened and slightly caramelized. Stir in minced garlic and cook for an additional 30 seconds until fragrant. Remove vegetables from the skillet and set aside.

Step 3: Cook Ground Beef

In the same skillet, add the ground beef. Cook over medium heat for 6–8 minutes, breaking it up with a spatula until browned. Drain any excess fat if desired.

Step 4: Season and Combine

Add Worcestershire sauce, salt, and pepper to the cooked beef. Stir to combine. Then, return the sautéed vegetables to the skillet and mix evenly with the beef.

Step 5: Add Cream Cheese

Lower the heat slightly and stir in 8 oz of cream cheese until melted and incorporated. The mixture should be creamy and evenly coated.

Step 6: Assemble the Casserole

Transfer the beef and vegetable mixture into the prepared baking dish. Layer provolone cheese evenly over the top, followed by shredded mozzarella cheese.

Step 7: Bake

Place the casserole in the preheated oven and bake 15–20 minutes, or until the cheese is fully melted and slightly golden. For a bubbly top, you can broil for 1–2 minutes at the end.

Step 8: Serve

Let the casserole rest for 5 minutes before serving. This allows the layers to set slightly and makes serving easier.
