This rich and creamy Roasted Chestnut and Garlic Aioli blends nutty, caramelized chestnuts with savory roasted garlic, creating a luxurious dip or spread that's perfect for autumn-inspired dishes. Its velvety texture and deep, earthy flavor make it an excellent accompaniment to roasted meats, vegetables, and crusty bread.
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.
