  • 1 yellow bell pepper, seeded and diced

  • 1 medium zucchini, diced

  • 2 tbsp olive oil

  • ½ tsp fine salt, plus more to taste

  • ¼ tsp freshly ground black pepper, plus more to taste

  • 1 tsp dried Italian herb blend (oregano, basil, thyme)

Step-by-Step Cooking Directions

1. Preheat & Prep
   Preheat your oven to 180 °C (350 °F). Lightly grease an 8–9-inch ovenproof skillet or baking dish with a thin film of olive oil.

2. Sauté the Leek
   In the prepared skillet over medium heat, warm 2 tbsp olive oil. Add the sliced leek and sauté for 2–3 minutes, stirring occasionally, until it begins to soften and turn translucent.

3. Add Bell Peppers & Zucchini
   Stir in the diced red and yellow bell peppers and zucchini. Season with ½ tsp salt, ¼ tsp pepper, and 1 tsp Italian herbs. Cook for 5–7 minutes, stirring every minute or so, until the peppers begin to soften and the zucchini releases some moisture but still retains a slight bite.

4. Incorporate Garlic & Green Onions
   Add the garlic and green onions to the pan. Stir thoroughly to combine, then cook for an additional 2–3 minutes, taking care not to let the garlic brown (which can impart bitterness). Remove vegetables to a plate if your skillet is small, or simply push them to the edges to make room for the eggs.

5. Whisk the Eggs
   In a medium bowl, crack 4 eggs. Whisk vigorously until the yolks and whites are fully combined and slightly frothy. Taste and adjust seasoning with a pinch of salt and pepper.

6. Combine & Bake
   Pour the whisked eggs evenly over the vegetables in the skillet, tilting the pan gently so the eggs fill all gaps. Sprinkle the grated cheddar cheese in an even layer on top of the eggs. Transfer the skillet to the preheated oven and bake 15 minutes, or until the frittata is set in the center and the cheese is melted and golden around the edges.

7. Rest & Garnish
   Remove from oven and let rest 5 minutes to allow the custard to finish setting. Top with chopped parsley or basil and serve warm, cut into wedges. Offer lemon wedges alongside for a bright finish.

The Origins and Popularity of the Recipe

Frittatas trace their lineage back to ancient Roman times, evolving through Italian cucina povera (peasant cooking) as a practical way to use leftovers and whatever vegetables were in season. The technique of combining eggs with sautéed produce and finishing the dish in an oven or broiler spread across Europe; by the Renaissance, variations were common in Spain, France, and beyond. Today, the frittata’s adaptability—incorporating local herbs, cheeses, meats, or vegetables—makes it a global staple for its simplicity, nutrition, and crowd-pleasing nature.

Common Mistakes to Avoid

• Overcrowding the Pan: Ensures even cooking; sauté in batches if needed.

Pairing Recommendations

Cooking Tips
