Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a baking dish or six individual oven-safe foil containers with olive oil.

Step 2: Cook the Ground Beef

Heat olive oil in a large skillet over medium heat.

Add the ground beef and cook for approximately 6–8 minutes, breaking it apart with a wooden spoon until browned and fully cooked.

Drain excess fat if necessary.

Step 3: Add the Vegetables

Add the sliced green, red, and yellow bell peppers along with the onion.

Cook for 4–5 minutes until the vegetables begin to soften.

Add minced garlic and cook for another 30 seconds.

Step 4: Season the Mixture

Stir in:

• Smoked paprika

• Turmeric

• Oregano

• Italian seasoning

• Black pepper

• Sea salt

• Worcestershire sauce

Pour in the beef broth and stir everything together.

Allow the mixture to simmer for 2–3 minutes.

Step 5: Assemble the Casserole

Transfer the beef and vegetable mixture into your prepared baking dish.

Spread everything evenly.

Sprinkle shredded mozzarella and provolone cheese generously over the top.

Step 6: Bake Until Golden

Place the casserole in the preheated oven.

Bake uncovered for 15–20 minutes, or until the cheese is melted, bubbling, and lightly golden.

For extra browning, broil for 1–2 minutes while watching carefully.

Ensure the beef mixture reaches a safe internal temperature of 160°F (71°C).

Step 7: Garnish and Serve

Remove the casserole from the oven and allow it to rest for approximately 5 minutes.

Sprinkle fresh parsley over the top.
