Lemon Basil Aioli Recipe

I keep a jar of this Lemon Basil Aioli in the fridge because it makes sandwiches, seafood, veggies, and fries instantly irresistible. Bright, creamy, and packed with fresh basil flavor, it’s the little sauce that steals the show.

I’m fully obsessed with this Lemon Basil Aioli because it hits that bright, creamy, herby spot I want on basically everything. I love the way fresh basil cuts through the richness of mayonnaise, so every swipe tastes fresh but still totally satisfying.

Burgers, fries, grilled chicken, roasted potatoes, sandwiches, random veggie dippers from the fridge, I want it all. And honestly, I adore a sauce that makes simple food feel more exciting without trying too hard.

But this one has attitude. Zippy, lush, punchy, and wildly addictive.

The kind of sauce I keep finding excuses to use again.

Ingredients

• Mayonnaise makes it creamy and rich, so don’t go low-fat if you want that dip vibe.
• Fresh basil brings a garden-y pop that keeps the aioli from tasting too heavy.
• Lemon juice cuts through the richness and makes everything taste brighter, basically instantly.
• Garlic gives it a little bite, but it won’t take over the whole bowl.
• Plus, these flavors are simple, familiar, and honestly way better than plain mayo.

Ingredient Quantities

• 1 cup mayonnaise (use full fat for creamier texture)
• 1/3 cup packed fresh basil leaves, finely chopped
• 2 tablespoons fresh lemon juice (about 1 medium lemon)

How to Make this

1. Finely chop the packed fresh basil leaves until you have about 1/3 cup.

2. Zest the lemon if you want extra brightness, then squeeze 2 tablespoons fresh lemon juice from about one medium lemon.

4. Place 1 cup mayonnaise in a medium bowl.

5. Add the chopped basil, lemon juice, and minced garlic to the mayonnaise.

Lemon Basil Aioli Recipe Substitutions and Variations

• Mayonnaise: Greek yogurt for tang and lower fat, sour cream for richness, mashed avocado for a green, creamy alternative
• Basil: Fresh parsley for a clean herbaceous note, cilantro for bright, citrusy flavor, tarragon for subtle anisey complexity
• Lemon juice: Fresh lime juice for similar acidity with a different citrus profile, white wine vinegar for gentle acidity, rice vinegar for milder tang
• Garlic: Roasted garlic for mellow, sweet depth, 1/4 teaspoon garlic powder for convenience, finely minced shallot for a milder allium note

Pro Tips

1. Use a mortar and pestle or a mini food chopper to bruise the basil with a pinch of salt before adding it. That releases more aroma and gives you a brighter, more integrated basil flavor without large leaf bits.

2. Let the mayo sit longer than 30 minutes when possible, up to a few hours. Chilling allows the lemon and garlic to mellow and the basil to infuse more fully, yielding a rounder, more cohesive sauce.

3. If you want a smoother, more emulsified texture, whisk in a teaspoon of olive oil or a splash of buttermilk while stirring. It loosens the mayo a touch and carries the herb flavor more evenly.

4. Adjust garlic and lemon gradually while tasting. Fresh garlic can bite hard and lemon can overpower, so add small amounts, taste, then fine tune. This keeps the basil as the star.
