The Story Behind the Recipe
Roasted Chestnut and Garlic Aioli is an exquisite condiment that beautifully merges the nuttiness of roasted chestnuts with the deep, savory richness of roasted garlic. This unique take on aioli brings warmth and depth to a classic Mediterranean sauce, making it an ideal accompaniment for cooler seasons, particularly autumn and winter.
The Inspiration Behind the Recipe
Aioli is a staple in Mediterranean cuisine, traditionally made with garlic, olive oil, and sometimes egg yolks or mustard to aid emulsification. It is widely used in French, Spanish, and Italian gastronomy, often serving as a flavorful dipping sauce or spread. This variation, inspired by the seasonal abundance of chestnuts, adds an unexpected sweetness and creamy texture to the robust, garlicky foundation.
Chestnuts have long been a cherished ingredient in European and Asian cooking. During autumn, one of the most nostalgic traditional activities is roasting chestnuts, their naturally sweet and earthy flavor becoming more pronounced with heat. By incorporating them into aioli, this recipe creates a delightful balance between nutty caramelization and piquant garlic notes.
Roasted garlic, on the other hand, softens in both texture and flavor when exposed to heat. Instead of its typical pungency, roasting coaxes out its mild, buttery-sweet undertones. Pairing this gentle roasted garlic with chestnuts creates an aioli that is ultra-smooth and nuanced in complexity.
The Cooking Process
Roasting the Chestnuts
The key to achieving the best texture in this dish starts with properly roasted chestnuts. By scoring each chestnut with an ‘X’ before roasting, you ensure that steam from within can escape, preventing them from bursting. Roasting at 400°F (200°C) for about 20 minutes allows for that characteristic caramel-like sweetness to develop.
After roasting, peeling the chestnuts while they are still warm helps remove both the outer shell and the thin, bitter inner membrane more easily. The resulting flesh is subtly sweet, starchy, and nutty—perfect for blending into a silken aioli.
Roasting the Garlic
Roasted garlic lends an almost buttery depth to the aioli. To prepare it, slicing off the top of a garlic head exposes the cloves, which are then drizzled with olive oil and roasted until tender and golden-brown. This slow-roasting process tames garlic’s sharpness and accentuates its sweeter notes, making it a sublime match for the roasted chestnuts.
Blending and Emulsification
Once the chestnuts and garlic are prepared, everything is pulsed in a food processor along with lemon juice and Dijon mustard. The acidity of the lemon juice brightens the overall flavor, preventing the mixture from becoming overly heavy. Dijon mustard helps stabilize the emulsion, ensuring the aioli maintains a smooth, creamy consistency.
As the olive oil is gradually drizzled into the food processor, the mixture transforms into a thick, luscious aioli. This slow incorporation is crucial, as it allows the oil to emulsify evenly, preventing separation. Finally, salt and freshly ground black pepper add the finishing touches, enhancing the overall balance of flavors.

Roasted Chestnut and Garlic Aioli
Ingredients
- 1 cup chestnuts roasted and peeled
- 1 head garlic roasted
- 1 tbsp lemon juice freshly squeezed
- 1 tsp Dijon mustard
- 1 cup extra virgin olive oil
- 1 tsp salt to taste
- 1 tsp black pepper freshly ground
Instructions
- Preheat the oven to 400°F (200°C). Using a sharp knife, score an ‘X’ on each chestnut to allow steam to escape while roasting.
- Place the chestnuts on a baking sheet and roast for 20 minutes, shaking the pan halfway through. Once done, let them cool slightly before peeling.
- Slice off the top of the garlic head to expose the cloves. Drizzle with olive oil, wrap in foil, and roast at 400°F (200°C) for 30-35 minutes until soft and caramelized.
- In a food processor, combine the peeled chestnuts, roasted garlic (squeezed from the cloves), lemon juice, and Dijon mustard. Pulse until a paste forms.
- Slowly drizzle in the olive oil while blending to create a creamy, emulsified aioli. Season with salt and black pepper to taste.
- Let the aioli chill in the refrigerator for at least 30 minutes to allow flavors to meld before serving.
Notes
- For a smokier flavor, roast the chestnuts over an open flame instead of in the oven.
- If the mixture is too thick, add water or a little more lemon juice.
