I made these flatbreads on a Tuesday when I had half a container of labneh to use up and nothing particularly interesting in the fridge. Canned lentils, one red onion, harissa — basically pantry stuff. The result was so good I made them again two days later on purpose.
The toaster oven is genuinely perfect for this. The small space gets hot fast and gives those onion wedges real caramelized edges in under 20 minutes. A full-size oven would work, but honestly it feels like overkill for two flatbreads. If you don’t have a toaster oven with convection yet, this recipe is a solid argument for getting one — that circulating heat is what makes the onions jammy instead of just steamed.
The flavor combination here is straightforward but it works: spicy, slightly smoky harissa onions against cool garlicky labneh, earthy lentils for bulk, and a crispy flatbread underneath to hold it all together. The pomegranate seeds aren’t required but if you have them, use them. That little burst of sweetness cuts through the heat nicely. A good toaster oven baking sheet lined with foil makes cleanup about thirty seconds of work, which I appreciate.
This is a vegetarian recipe and it’s filling enough to be a real dinner, not just a snack. Two flatbreads serves two people — or one very hungry person who has been doing yard work.
Toaster Oven Harissa Roasted Red Onion and Lentil Flatbreads with Herbed Labneh
Spiced roasted red onions and hearty lentils piled onto crispy flatbread with cool, garlicky labneh. Ready in about 30 minutes and genuinely satisfying.
Ingredients
For the roasted onions
For the lentils
For the herbed labneh
To assemble
Instructions
-
Preheat your toaster oven to 425°F. Line the toaster oven tray with foil — the harissa will stain, trust me.
-
Toss the red onion wedges with the harissa paste, 1 tablespoon olive oil, honey, cumin, a good pinch of salt, and some black pepper. Spread them out on the lined tray in a single layer.
-
Roast the onions for 14–16 minutes, flipping once at the halfway point, until they're jammy and a little charred at the edges. That char matters. Don't pull them too early.
-
While the onions roast, stir together the drained lentils, 1 teaspoon olive oil, smoked paprika, garlic powder, and salt in a small bowl. Set aside — they don't need cooking, just seasoning.
-
Mix the labneh with the grated garlic, parsley, lemon juice, and a pinch of salt. Taste it and adjust. It should be bright and garlicky. Set aside.
-
When the onions are done, transfer them to a bowl. Brush each flatbread lightly with olive oil on both sides.
-
Place the flatbreads directly on the toaster oven rack (or on the tray) and toast for 3–4 minutes until crispy on the edges but still a little chewy in the center.
-
Spread a generous layer of herbed labneh across each flatbread. Top with the seasoned lentils, then pile on the harissa onions. Scatter over the pomegranate seeds if you're using them, and finish with the torn mint.
-
Eat immediately. These do not wait well — the flatbread softens fast once the toppings go on.
Notes
Labneh is sold at most Middle Eastern grocery stores and a lot of regular supermarkets now — look near the specialty cheeses or hummus. If you genuinely can't find it, Greek yogurt strained through a cheesecloth for an hour works. The harissa brand matters more than you'd think; some are mild, some will genuinely clear your sinuses. Start with 1 tablespoon if you're not sure about the heat level, taste, and go from there. Pomegranate seeds are optional but they add a little pop of sweet-tart that really works here. Leftovers: store the components separately in the fridge for up to 2 days and assemble fresh.
