👩‍🍳 Instructions

Step 1: Preheat Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13 baking dish if not using an oven-safe skillet.

Step 2: Cook the Beef

In a large skillet over medium heat, add the ground beef and diced onion. Cook until the beef is browned and the onion is soft, breaking the meat up as it cooks.
Drain excess grease if needed.

Add garlic, salt, pepper, smoked paprika, onion powder, and garlic powder. Stir well and cook for 1 more minute until fragrant.

Step 3: Make It Creamy

Reduce heat to low. Stir in the sour cream, mayonnaise, and mustard (if using). Mix until everything is evenly coated and creamy.

Step 4: Assemble the Casserole

Transfer the beef mixture to your baking dish (or keep it in the oven-safe skillet).
Top evenly with shredded cheddar and mozzarella cheese.
Sprinkle the crumbled bacon over the top.

Step 5: Bake

Bake uncovered for 20–25 minutes, or until the cheese is fully melted, bubbly, and lightly golden.

Step 6: Garnish & Serve

Remove from the oven and let rest for 5 minutes.
Garnish with chopped green onions or parsley if desired.

Serve hot and enjoy!
