These caramelised onion flatbreads offer a sophisticated twist on a savoury snack, combining the sweetness of slowly softened onions with the tangy richness of crème fraîche. The dough is subtly scented with nigella seeds, providing a nutty, aromatic base that complements the fresh thyme and honey-glazed topping. It is a wonderful vegetarian option for those who enjoy the classic flavours of a French Tarte Flambée but prefer a softer, more substantial crust.
Perfect as a light lunch served alongside a crisp green salad, these flatbreads also make an excellent starter for a weekend dinner party. The dough and onion topping can be prepared a day in advance, making the final assembly and baking process effortless. Whether you are hosting friends or looking for a comforting homemade treat, these individual bakes deliver a professional finish with minimal fuss.

Ingredients for Caramelized-Onion Flatbreads with Crème Fraîche
60ml plus 1 tablespoon warm water (41°C to 46°C)
3/4 teaspoons active dry yeast
90g plus 2 tablespoons plain flour
3/4 teaspoons nigella (kalonji) seeds
1/2 teaspoons salt
1 tablespoon butter, room temperature
2 tablespoons extra-virgin olive oil
450g onions (about 2 medium), cut into 1/3-inch-thick wedges through root ends
2 teaspoons chopped fresh thyme
1 teaspoon honey
1 tablespoon Sherry wine vinegar
120ml crème fraîche
1 large egg
1/2 teaspoons salt
1/4 teaspoons ground black pepper
Semolina flour (pasta flour)* or cornmeal
2 tablespoons chopped fresh chives
How to make Caramelized-Onion Flatbreads with Crème Fraîche
Whisk 60ml plus 1 tablespoon warm water and yeast in small bowl; let stand until yeast is dissolved, about 10 minutes.
Mix flour, nigella seeds, and salt in medium bowl. Add yeast mixture and stir with wooden spoon until mixture clumps together. Add butter; mix until incorporated. Turn dough out onto lightly floured work surface and knead until smooth and elastic, about 5 minutes. Divide dough into 6 equal pieces; roll each into ball. Place on baking sheet; cover with plastic wrap. (Can be prepared 1 day ahead. Keep covered and refrigerate.)
Heat oil in large nonstick skillet over medium-high heat. Add onion wedges to skillet and cook without turning until beginning to brown, about 7 minutes. Carefully turn onions over; reduce heat to medium and continue to cook until onions are tender and brown, occasionally stirring gently, about 10 minutes. Add thyme and honey; cook 1 minute. Stir in vinegar. Seasonto taste with salt and pepper. Remove skillet from heat. Cool. (Can be prepared 1 day ahead. Cover and refrigerate.)
Let dough rise in warm draft-free area until doubled, about 1 hour. Whisk crème fraîche and egg in small bowl to blend. Stir in 1/2 teaspoons salt and 1/4 teaspoons pepper.
Preheat oven to 232°C. Sprinkle 2 rimmed baking sheets lightly with semolina flour. Roll out each dough ball to 5-inch round. Transfer 3 rounds to each prepared baking sheet. Let rest 10 minutes. Pierce dough rounds all over with fork. Spread 1 generous tablespoon crème fraîche mixture over each dough round, leaving 1/4-inch plain border. Arrange onions evenly atop each; drizzle lightly with crème fraîche mixture (mixture may spill over edges of dough).
Bake flatbreads until crusts are puffed and golden, about 12 minutes. Transfer to plates; sprinkle with chives.
