Full Recipe

Ingredients

• 3 medium potatoes (peeled and cut into chunks)

• Enough water to cover the potatoes (plus 15 minutes soaking)

• 4–5 tablespoons vegetable oil

• 2 onions, finely chopped

• 2 red bell peppers, diced

• 3 green bell peppers, diced

• 3 eggs

• Salt, to taste

• 1.5 cups (300 ml) milk

• 2 cups (240 g) all-purpose flour

• 3 tomatoes, thinly sliced

• 150 g cheddar cheese, grated

• Fresh parsley, chopped (for garnish)

Cooking Directions

1. Peel and cut the potatoes into chunks and place them in a bowl filled with water. Let them soak for 15 minutes to remove excess starch.

2. Heat 4–5 tablespoons of vegetable oil in a pan over medium heat. Lightly fry the chopped onions until they turn translucent. Add diced red and green peppers and sauté until they soften.

3. Drain the soaked potatoes and mash roughly or mash to your desired texture. Stir in the sautéed onions and peppers.

4. In a separate bowl, whisk together the eggs, milk, salt, and flour until the mixture is smooth and free of lumps.

5. Pour the batter over the potato and vegetable mixture and stir until well combined. Spread the mixture evenly on a baking sheet lined with parchment paper.

6. Bake in a preheated oven at 180 °C (356 °F) for 30–35 minutes, until the edges are golden and the middle is set.

7. Remove from the oven and arrange the tomato slices over the top of the bake. Sprinkle grated cheddar cheese evenly over the tomatoes. Return to the oven for another 15 minutes, until the cheese is melted and bubbly and the tomatoes begin to roast.

8. Remove from the oven and let it cool slightly before slicing into portions. Garnish with chopped parsley and serve warm or at room temperature.

Why You’ll Love This Recipe

This bake feels like comfort food but unlike traditional pizza it’s lighter, more vegetable-forward, and easy to customize. With crispy edges and a tender interior, every slice brings together the creamy richness of potatoes, sweet pepper and onion flavor, bright tomato topping, and gooey cheese in a flavor-packed bite. It’s fun to slice, portable enough for lunches, and crowd-pleasing at brunch or dinner.

The Origins and Inspiration Behind the Dish

Inspired by Mediterranean vegetable pies and rustic baking traditions, this dish blends elements of Greek spanakopita (minus the phyllo) and Italian vegetable tarts. Rather than using pastry, the potato base adds heartiness and simplicity. It’s nostalgic, home-style, and perfect for kitchens that want big flavor with minimal fuss.

Ingredient Spotlight

Potatoes serve as the foundation, providing starchiness and comfort. Bell peppers and onions bring sweet, aromatic notes and nutrients. Eggs and milk create a custardy binder that gives the slice structure and fluff. Tomatoes add acidity and freshness on top, contrasted beautifully by the melted cheddar cheese. Parsley adds a final pop of color and herbaceous brightness.

Storage and Reheating Tips

Store leftover slices in an airtight container in the fridge for up to 4 days. Reheat in a 180 °C oven for 5–7 minutes to restore crispness, or microwave individual pieces for 40–60 seconds. Slices freeze well too—just thaw in the fridge and reheat using the oven for best texture.

Common Variations to Try

Customize to your taste or what you have on hand. Swap cheddar for mozzarella, feta, or goat cheese. Stir in cooked bacon, mushrooms, or spinach. Spice lovers can add chili flakes or paprika. For a grain-free version, use almond flour instead of all-purpose flour (adjust moisture). You can switch up the veggies by using zucchini or carrots instead of peppers.

Pairing Recommendations

Serve this slice with a crisp green salad dressed in olive oil and lemon for a light meal. It’s also great alongside a simple soup like tomato or lentil for a heartier combo. At brunch, pair it with poached eggs or roasted avocado. For drinks, try iced herbal tea, light-bodied red wine, or sparkling water with lemon.

Health Benefits

This bake is a creative way to incorporate vegetables into a satisfying dish. Bell peppers and tomatoes pack in vitamins A and C, while potatoes offer potassium and fiber. Eggs provide protein and healthy fats, and using less oil than a fried dish keeps it balanced. It’s lower in refined carbs and processed elements than pizza, yet delivers on indulgence and flavor.

Conclusion

This Potato Vegetable Oven Slice is a delicious alternative to pizza—easier to make, loaded with veggies, and perfect for any meal of the day. Simple ingredients transform into something extraordinary: cheesy, savory, tender, and satisfying. Try it once and you’ll likely make it again and again, because it’s that kind of dish—honoring humble roots with big, comforting flavor.
