Tandoori Onion Chutney Recipe

Prepare and char the onions

Slice the red onion into thin to medium slices (about 1 cup once sliced). Heat a skillet or cast-iron pan over medium-high heat until hot. Add 1 tablespoon vegetable oil and spread it. Add the sliced onion in a single layer and let them cook undisturbed for 2–3 minutes until they begin to brown. Stir and continue to cook, allowing edges to char slightly — total cooking 6–8 minutes until softened and lightly charred. The goal is a tandoori-like char without burning. Transfer the onions to a plate to cool slightly.

Char garlic and ginger (optional)

In the same hot pan, add the whole garlic cloves and the chopped ginger. Sear them 1–2 minutes until light golden and aromatic (this mellows raw bite). Remove and let cool. If you prefer a raw, brighter garlic/ginger flavor, skip this step and use them raw.

Toast whole spices for tempering

In a small teaspoon of oil (mustard or neutral), warm the cumin seeds in a tiny pan over low heat until they become fragrant and begin to pop, about 20–30 seconds. Remove from heat to prevent burning. This oil and toasted cumin will be used to finish the chutney.

Blend the base

In a small blender or food processor, combine the charred onions, seared garlic and ginger, 3 tablespoons plain yogurt, 1 teaspoon red chili powder (use Kashmiri for color), 1 teaspoon ground cumin, 1/2 teaspoon garam masala, 1/2 teaspoon smoked paprika (if using), 1 teaspoon salt, and 1/2 teaspoon brown sugar or jaggery. Pulse several times until the mixture becomes a coarse paste.

Adjust texture and acidity

With the blender running, add up to 2 tablespoons water, a tablespoon at a time, until the chutney reaches a thick, spreadable consistency. Taste and add 1 tablespoon fresh lemon juice to brighten, and more salt if needed. If you want more tang, add an extra 1/2 tablespoon lemon juice. Blend briefly to incorporate.

Finish with tempering

Stir the toasted cumin and the warmed teaspoon of oil into the chutney (or pour it over the chutney to bloom the aroma). This adds a warm, nutty finish reminiscent of tandoori flavors.

Garnish and rest

Transfer chutney to a bowl, garnish with chopped cilantro if using. Let it rest at least 15–30 minutes at room temperature for flavors to meld (refrigerate for longer storage).

Serving suggestions

Serve chilled or at room temperature as a dip with grilled meats, kebabs, tandoori chicken, samosas, sandwiches, or as an accompaniment to flatbreads and rice. The chutney keeps in an airtight container in the refrigerator for up to 4–5 days.
