Full Recipe

Ingredients

For the Potato Layer:

• 3 large potatoes (900 grams), peeled and thinly sliced

• 300 grams mozzarella cheese, grated

• 2 tablespoons vegetable oil (20 ml)

• 1 teaspoon salt (4 grams), or to taste

For the Beef Filling:

• 500 grams minced beef

• 2 tablespoons vegetable oil (20 ml)

• 1 medium onion, finely chopped

• 2 green peppers, diced

• 1 red pepper, diced

• 1 yellow pepper, diced

• 3 cloves garlic, minced

• 100 g tomato sauce

• ½ teaspoon paprika

• ½ teaspoon thyme

• ½ teaspoon turmeric

• Fresh parsley, finely chopped, for garnish

Cooking Directions

1. Preheat your oven to 200°C (392°F). Peel and slice the potatoes into thin rounds. In a large bowl, toss them with vegetable oil and salt. Arrange the slices in a greased casserole dish, overlapping slightly to form a base.

2. Bake the potatoes for 30 minutes, until they’re partially cooked and golden around the edges.

3. Meanwhile, heat vegetable oil in a skillet over medium heat. Add chopped onions and garlic, cooking for 3–4 minutes until fragrant.

4. Stir in minced beef, breaking it apart with a spoon, and cook until browned.

5. Add the diced green, red, and yellow peppers, sautéing for 5–6 minutes until softened.

6. Mix in the tomato sauce, paprika, thyme, turmeric, and a pinch of salt. Cook another 5 minutes to let flavors meld, then remove from heat.

7. Spread the beef and pepper filling evenly over the baked potato base.

8. Top generously with grated mozzarella cheese.

9. Return the dish to the oven and bake for 15–20 minutes, or until the cheese is melted, golden, and bubbling.

10. Garnish with fresh parsley, let cool slightly, and serve warm.

The Origins and Inspiration Behind the Dish

Casseroles are beloved across cultures, often created from necessity as a way to stretch ingredients into something filling for the family. This dish is inspired by traditional European layered potato and meat bakes, but it incorporates the vibrancy of Mediterranean flavors with the use of peppers, garlic, and aromatic spices. It’s a recipe that feels old-fashioned in its heartiness, yet modern in its colorful, fresh approach. The use of three different bell peppers doesn’t just add flavor—it brings a visual pop that makes this casserole as beautiful as it is delicious.

Ingredient Spotlight

Potatoes form the sturdy foundation of this casserole, providing both structure and comfort. Mozzarella is the melty crown jewel, offering that stretchy, cheesy finish we all crave. Minced beef is the protein powerhouse, giving the dish substance and savoriness, while onions and garlic provide the aromatic base. The trio of peppers adds natural sweetness, crunch, and vibrant color. The paprika, thyme, and turmeric create depth and warmth, taking this casserole beyond the ordinary into something memorable.

Storage and Reheating Tips

Leftovers reheat beautifully, making this casserole a fantastic make-ahead dish. Store cooled portions in an airtight container in the refrigerator for up to 3 days. To reheat, place a slice in the microwave for 1–2 minutes or reheat in the oven at 180°C (356°F) until warmed through. If freezing, bake the casserole fully, let it cool completely, then wrap tightly in foil and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Common Variations to Try

This recipe is highly adaptable. Swap mozzarella for cheddar, gouda, or even a spicy pepper jack if you want extra kick. Add layers of zucchini, eggplant, or mushrooms for more veggie variety. If you prefer poultry, ground chicken or turkey works just as well. For a richer version, add a thin layer of béchamel sauce between the potatoes and beef. You can also sprinkle breadcrumbs mixed with parmesan on top before the final bake for a golden, crunchy crust.

Pairing Recommendations

This casserole pairs wonderfully with fresh, light sides that balance its richness. A crisp green salad with lemon vinaigrette, roasted vegetables, or steamed broccoli makes a great companion. For something heartier, serve it with garlic bread or a side of buttered rice. As for drinks, red wine like Merlot or Shiraz enhances the depth of the beef, while a chilled white like Sauvignon Blanc complements the peppers. For non-alcoholic options, a sparkling water with lemon or a light iced tea pairs beautifully.

Health Benefits

Despite being comfort food, this casserole offers solid nutritional value. Potatoes provide potassium and fiber, while bell peppers are rich in vitamin C and antioxidants. The lean minced beef contributes high-quality protein and iron, supporting energy and muscle health. Garlic and onions contain compounds that benefit heart health, and mozzarella adds calcium for strong bones. By baking instead of frying, this dish cuts down on unnecessary oils, making it a healthier indulgence.

Potato and Beef Casserole with Mozzarella and Peppers is the kind of recipe that turns everyday ingredients into something extraordinary.
