This vibrant grilled courgette and leek frittata is a sophisticated take on a vegetarian classic, perfect for a weekend brunch or a light summer supper. By grilling the vegetables first, you lock in a wonderful smoky depth that pairs beautifully with the creamy texture of the eggs. The addition of harissa provides a gentle heat which cuts through the richness of the crème fraîche, making every bite feel fresh and balanced.
Ideal for outdoor dining or a simple mid-week meal, this recipe is incredibly versatile and highlights seasonal produce at its best. If you don't have a barbecue, a heavy-based griddle pan works just as well to achieve those characteristic char marks. Serve your frittata warm or at room temperature with a crisp green salad and some crusty sourdough for a complete and healthy homemade feast.

Ingredients for Grilled Frittata with Courgette, Leeks, Crème Fraîche and Harissa
1 large courgette (about 350g ), sliced lengthwise 1/3 inch thick
2 medium leeks, roots trimmed, top 2 inches discarded, leeks halved lengthwise and rinsed well
Extra-virgin olive oil, for brushing
1 1/2 teaspoons kosher salt, divided
Freshly ground black pepper
12 large eggs
60ml plus 2 tablespoons crème fraîche
2 teaspoons harissa, plus more for serving
2 tablespoons torn basil leaves
How to make Grilled Frittata with Courgette, Leeks, Crème Fraîche and Harissa
Back to contentsLight a grill or preheat a grill pan; if you're using a charcoal grill, leave one spot cooler for indirect cooking. Lightly brush both sides of the courgette and the leeks with olive oil and season with 1/2 teaspoons salt and pepper. Grill the courgette over high heat, turning once, until nicely browned and tender, about 2 minutes per side. Transfer to a work surface, let cool slightly and slice crosswise 1/2 inch thick.
Grill the leeks over high heat until grill marks form, about 2 minutes per side, then move the leeks to a cooler part of the grill and grill over moderately low heat, turning occasionally, until just tender, about 15 minutes. Transfer the leeks to a work surface and let cool slightly. Remove the outer leaf and thinly slice the leeks crosswise, discarding any tough dark green pieces.
Turn the grill burners to moderate heat or, if you're using a charcoal grill, let the hot coals cool slightly. Brush a seasoned 12-inch cast-iron skillet generously with olive oil and set it on the grill.
In a large bowl, whisk the eggs with 40g the crème fraîche and remaining 1 teaspoon salt. Stir in the cooled vegetables. When the skillet is hot, carefully pour in the eggs and vegetables. Using a spoon, carefully dollop the remaining 2 tablespoons of the crème fraîche and the 2 teaspoons of harissa around the top of the eggs. Close the grill and cook the frittata for about 15 minutes, moving the skillet a few times to make sure it's evenly heated, until the eggs are puffed and set.
Let the frittata cool slightly, then garnish with the basil leaves. Slice the frittata into wedges and serve, passing more harissa at the table.
