Tools You’ll Need

Large skillet
Mixing bowls
Casserole dish (9×13 inches)
Spatula
Sharp knife & cutting board

Step-by-Step Instructions

Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish and set it aside.

Step 2: Cook the Beef
Heat olive oil in a large skillet over medium-high heat.
Add the ground beef and cook until browned, breaking it up with a spatula.
Drain excess fat if necessary and set the beef aside.

Step 3: Sauté the Vegetables
In the same skillet, add sliced onions and bell peppers.
Cook for 5-7 minutes, stirring occasionally, until vegetables are soft and slightly caramelized.
Add minced garlic and cook for another 1 minute.
Return the cooked beef to the skillet and stir in Worcestershire sauce, salt, pepper, smoked paprika, and crushed red pepper flakes (if using).
Mix well and cook for another 2-3 minutes. Remove from heat.

Step 4: Make the Cheese Mixture
In a medium bowl, mix together cream cheese, sour cream, mayonnaise, Dijon mustard, onion powder, and garlic powder until smooth and creamy.

Step 5: Combine and Layer
Spread the cheese mixture evenly over the bottom of the greased casserole dish.
Spoon the beef and pepper mixture evenly on top of the cheese layer.
Sprinkle shredded mozzarella and provolone cheeses over the beef mixture.

Step 6: Bake
Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly.
For a golden-brown top, broil for an additional 2-3 minutes, watching closely to prevent burning.

Step 7: Cool and Serve
Remove from oven and let it sit for 5-10 minutes to set.
Slice and serve hot, garnished with chopped parsley if desired.

Tips for the Best Casserole

Adjust Cheese to Taste – Feel free to mix in other low-carb cheeses like cheddar or Monterey Jack.
Make it Spicier – Add jalapeños or a dash of hot sauce if you like a kick.
Double the Batch – This dish freezes well, so make extra for future meals.
Don’t Skip the Resting Time – It helps the casserole firm up for cleaner slices.

Serving Suggestions
Mixed Green Salad – A crisp, fresh salad balances the richness of the casserole.
Cauliflower Rice – Keeps it low-carb while soaking up the cheesy goodness.
Zucchini Noodles – Light and nutritious for a veggie-packed side.
Grilled Veggies – Add some smoky, charred vegetables for extra flavor.
