Step-by-Step Instructions
1. Roast the Potatoes
Preheat the oven to 425°F (220°C).
Place the quartered potatoes in a large baking dish.
Add olive oil, garlic powder, smoked paprika, salt, and black pepper.
Toss until evenly coated.
Roast for 20–25 minutes, stirring once halfway through, until the potatoes begin to turn golden.
2. Cook the Ground Beef
While the potatoes roast, heat a large skillet over medium-high heat.
Add the ground beef and cook for 6–8 minutes, breaking it into small crumbles until browned.
Drain excess grease if necessary.
3. Season the Beef
Add minced garlic, Italian seasoning, smoked paprika, onion powder, salt, and black pepper.
Stir in Worcestershire sauce, tomato paste, and beef broth.
Cook for another 2–3 minutes, until the beef is richly seasoned and most of the liquid has reduced.
4. Add the Bell Peppers
Remove the potatoes from the oven.
Add the chopped bell peppers, sliced onion, and cooked beef to the baking dish.
Gently toss everything together so the beef and vegetables are evenly distributed.
5. Add the Cheese
Sprinkle cheddar and mozzarella generously over the beef and vegetables.
Finish with grated Parmesan.
Return the casserole to the oven.
6. Bake Until Golden
Reduce the oven temperature to 400°F (200°C).
Bake uncovered for another 15–20 minutes, or until the peppers are tender and the cheese is completely melted and bubbling.
For a more golden topping, broil for 1–2 minutes at the end while watching carefully.
7. Serve
Remove the casserole from the oven and allow it to rest for about 5 minutes.
Sprinkle generously with fresh parsley and cracked black pepper.
Serve warm while the potatoes are tender and the cheese is gooey.
Cooking Tips
- Cut the potatoes into similar-sized pieces so they roast evenly.
- Pre-roasting the potatoes helps them develop crispy golden edges.
- Drain excess fat from the ground beef to prevent the casserole from becoming greasy.
- Keep the bell pepper pieces fairly large so they stay tender without becoming mushy.
- Freshly shredded cheese melts more smoothly than packaged pre-shredded cheese.
