This classic roasted tomato salsa is a versatile vegan staple that brings a smoky, charred depth of flavour to any table. By grilling the tomatoes, white onions and chillies until blackened, the natural sugars caramelise to create a rich base that far surpasses any shop-bought alternative. The combination of smooth purée and hand-chopped vegetables ensures a restaurant-style texture that balances heat with the bright acidity of fresh lime.
Perfect as a vibrant plant-based appetiser or a zesty topping for tacos, this homemade sauce is a healthy, low-fat addition to your repertoire. It is best enjoyed at room temperature to allow the coriander and garlic notes to fully develop. Serve a generous bowl alongside crunchy tortilla crisps for an effortless crowd-pleaser at your next gathering.

Ingredients for The Only Salsa You Need
900g tomatoes, cored, cut in half crosswise
1 medium white onion, sliced into 1/4"-thick rounds
3 serrano chillies
3 garlic cloves, unpeeled
Kosher salt
2 tablespoons fresh lime juice
2 tablespoons finely chopped coriander
Tortilla crisps (for serving)
How to make The Only Salsa You Need
Back to contentsHeat grill. Place tomatoes cut side down on a foil-lined rimmed baking sheet. Fit onion, chillies, and garlic around tomatoes so everything is snug but not overlapping. Grill, turning onion and chillies once, until lightly charred, about 6 minutes for chillies and garlic and 15–18 minutes for tomatoes and onion.
Peel garlic and place in a food processor along with half of the tomatoes. Pulse until very smooth. Add remaining tomatoes and pulse until tomatoes are mostly broken up but mixture still has some texture. Transfer to a medium bowl. Finely chop onion and chillies and mix into purée; season with salt. Let cool. Stir in lime juice and coriander. Season salsa with more salt if needed. Serve with chips.
