Ingredients
1½ pounds (680g) beef steak, cut into bite-sized pieces
1 tablespoon olive oil
1 medium onion, diced
1 red bell pepper, sliced
1 green bell pepper, diced
2 cloves garlic, minced

Optional: 1 tablespoon Worcestershire sauce
Equipment Needed
Large skillet
Mixing spoon
9×13-inch baking dish
Oven
Instructions
Step 1: Prepare the Beef
Preheat your oven to 375°F (190°C).
Heat olive oil in a large skillet over medium-high heat. Add the beef pieces and cook until browned on all sides, about 5–7 minutes.
Step 2: Add Vegetables
Add the onion, bell peppers, and garlic. Cook for another 4–5 minutes until the vegetables begin to soften.
Season with salt, pepper, paprika, and Worcestershire sauce if using.
Step 3: Assemble the Casserole
Transfer the beef mixture to a greased baking dish.
Sprinkle the mozzarella and cheddar cheeses evenly over the top.
Step 4: Bake
Bake uncovered for 20–25 minutes, or until the cheese is melted, bubbly, and lightly golden.
Step 5: Finish and Serve
Remove from the oven and let rest for 5 minutes.
Garnish with sliced green onions and serve hot.
Tips for Success
Use sirloin steak for tender bites of beef.
Add mushrooms for extra flavor.
For a spicy version, include diced jalapeños.
Freshly shredded cheese melts better than pre-packaged cheese.
