Ingredients
- 2 lbs ground beef (80/20 fat ratio preferred)
- 1 large onion, diced
- 2 large bell peppers (green, red, or mixed), diced
- 2 cloves garlic, minced
- 8 oz cream cheese, softened to room temperature
- 2 tbsp Worcestershire sauce
- Salt and pepper to taste
- 8 oz provolone cheese, sliced
- 1.5 cups mozzarella cheese, shredded
- 1 tbsp olive oil
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray. Heat olive oil in a large skillet over medium heat.
- Step 2: Add diced onions and bell peppers to the hot oil, cooking for 5-6 minutes until they start to soften and become fragrant.
- Step 3: Stir in minced garlic and cook for another 30 seconds, stirring constantly to prevent burning.
- Step 4: Add ground beef to the skillet, breaking it up with your spatula as it cooks. Season generously with salt and pepper, cooking for 7-8 minutes until completely browned with no pink remaining. Drain excess fat if needed.
- Step 5: Stir in Worcestershire sauce to coat the meat mixture for enhanced flavor. Reduce heat to low and add the softened cream cheese, stirring until completely melted and creamy.
- Step 6: Transfer the mixture to your prepared baking dish and spread evenly. Layer torn provolone pieces over the beef, then top with shredded mozzarella.
- Step 7: Bake for 22-25 minutes until cheese is melted, bubbly, and lightly golden on top. Let rest for 5 minutes before serving to allow flavors to meld together.
Tips & Variations
- Use a mix of bell pepper colors for a more vibrant dish and balanced sweetness.
- For extra flavor, add sliced mushrooms when cooking the onions and peppers.
- Substitute provolone with cheddar or Monterey Jack if preferred.
- To keep it extra low carb, skip any breadcrumbs or thickeners if you decide to add ingredients.

Can I use ground turkey instead of beef?
