This homemade Vadouvan spice blend is a sophisticated, French-inspired take on traditional Indian curry powder. Characterised by its sweet, aromatic base of caramelised onions, shallots and garlic, this vegan-friendly condiment offers a complex depth of flavour that shop-bought powders simply cannot match. The slow-roasting process intensifies the natural sugars in the vegetables, while delicate notes of fenugreek, cardamom and curry leaves provide a fragrant finish.
As a versatile kitchen staple, this savoury paste can be stirred into hearty lentil dals, rubbed onto roasted vegetables or used to base a delicate coconut milk sauce. Because it is handmade using fresh aromatics and quality ground spices, it serves as an excellent way to elevate simple weekday meals into gourmet dishes. Store it in the fridge or freezer to keep its vibrant flavour profile ready for your next culinary creation.

Ingredients for Vadouvan Spice Blend
900g onions, cut into 1-inch pieces
450g shallots, halved
12 garlic cloves, peeled
60ml vegetable oil
1 teaspoon fenugreek seeds
1 tablespoon thinly sliced fresh curry leaves (optional)
1 tablespoon ground cumin
1 teaspoon ground cardamom
1 teaspoon brown mustard seeds
3/4 teaspoons turmeric
1/2 teaspoons grated nutmeg
1/2 teaspoons hot red-pepper flakes
1/4 teaspoons ground cloves
an electric coffee/spice grinder or a mortar and pestle
How to make Vadouvan Spice Blend
Preheat oven to 177°C with rack in middle.
Pulse onions in 3 batches in a food processor until very coarsely chopped (there may be a few large pieces remaining), transferring to a bowl. Repeat with shallots, then garlic.
Heat oil in a deep 12-inch heavy nonstick skillet over high heat until it shimmers, then sauté onions, shallots, and garlic (stir often) until golden and browned in spots, 25 to 30 minutes
Grind fenugreek seeds in grinder or with mortar and pestle. Add to onion mixture along with remaining ingredients, 1 tablespoon salt, and 1 teaspoon pepper and stir until combined.
Transfer to a parchment-paper-lined large 4-sided sheet pan and spread as thinly and evenly as possible. Bake, stirring occasionally with a skewer to separate onions, until well browned and barely moist, 1 to 1 1/4 hours.
