Onion Aioli

Onion Aioli is a versatile and flavorful condiment that can elevate the taste of sandwiches, burgers, or grilled vegetables.

Its creamy texture and the blend of sweet, tangy, and savory flavors make it a favorite in many Mediterranean dishes.

Let’s dive into how to make this delightful spread.

Ingredients:

  • 1 medium-sized onion, finely chopped
  • 3 cloves of garlic, minced
  • 1 cup mayonnaise
  • 2 tablespoons olive oil
  • 1 tablespoon lemon juice
  • Salt and freshly ground black pepper to taste
  • Optional: 1 teaspoon of Dijon mustard or honey for extra flavor

Instructions:

  1. Heat the olive oil in a skillet over medium heat. Add the chopped onion and a pinch of salt. Cook, stirring occasionally, until the onions are golden brown and caramelized, about 15-20 minutes. Allow the onions to cool to room temperature.
  2. In a medium bowl, mix together the mayonnaise, minced garlic, lemon juice, and if using, Dijon mustard or honey. Stir until all the ingredients are well combined.
  3. Add the caramelized onions to the aioli base. Stir well to ensure the onions are evenly distributed throughout the mixture.
  4. Taste the aioli and season with salt and freshly ground black pepper. Adjust the lemon juice or add a splash more olive oil if needed.
  5. Cover the bowl with plastic wrap and refrigerate the onion aioli for at least an hour. This allows the flavors to meld together beautifully.
  6. Give the aioli a final stir before serving. Use it as a spread on sandwiches, a dip for veggies, or a sauce for grilled meats.

Tips:

Choose yellow or sweet onions for this recipe as they caramelize well, adding a natural sweetness to your aioli. Red onions can also be used for a more vibrant flavor.

When caramelizing onions, patience is key. Cook them low and slow to bring out their natural sugars and prevent burning. This process can’t be rushed if you want the perfect flavor.

If you’re not a big fan of raw garlic, reduce the amount or lightly sauté it with the onions to mellow its punch. Alternatively, for a stronger garlic flavor, increase the quantity or add a pinch of garlic powder.

If your aioli is too thick, thin it out with a bit of olive oil or lemon juice. If it’s too thin, add more mayonnaise until you reach the desired consistency.

Onion aioli can be stored in an airtight container in the refrigerator for up to a week. Stir well before each use, as the ingredients may separate slightly when chilled.
