Lemon Garlic Aioli

This lemon garlic aioli is creamy, bright, and packed with mellow roasted garlic flavor. It comes together with mayonnaise, fresh lemon juice, roasted garlic, salt, and pepper, making it an easy dip, spread, or finishing sauce.

This lemon garlic aioli recipe uses mayo as the base, so you do not have to make an emulsion, which means slowly whisking oil into egg yolks and garlic until it turns thick and creamy like traditional aioli. The roasted garlic gives the sauce a smoother, deeper flavor, while the lemon juice keeps it fresh and balanced. I love keeping this in the fridge for air fryer crab cakes, pan-seared tilapia, steak bites and potatoes, or roasted vegetables.

Why You’ll Love This Lemon Garlic Aioli

• Quick and easy: Since this recipe starts with mayonnaise, you get a creamy sauce without making an emulsion from scratch.
• Smooth garlic flavor: Roasted garlic is softer and slightly sweet, so the sauce tastes rich without being sharp.
• Easy to make ahead: The flavor gets even better after the aioli chills.
• Simple ingredients: You only need mayo, lemon juice, roasted garlic, salt, and pepper.

Ingredients Needed

• Mayonnaise: This gives the aioli its creamy base. I use store-bought mayo, but your favorite homemade mayonnaise works too.
• Roasted garlic cloves: Roasted garlic gives this sauce a mellow, savory garlic flavor. I use my air fryer roasted garlic bulbs because it is a quicker way to roast garlic without turning on the oven.
• Lemon juice: Fresh lemon juice brightens the sauce and balances the richness of the mayo.
• Sea salt: Helps bring out the garlic and lemon flavor.
• Black pepper: Adds a little warmth and keeps the sauce from tasting flat.

How to Make Lemon Garlic Aioli

Blend the sauce

Add the mayonnaise, roasted garlic cloves, lemon juice, sea salt, and black pepper to a food processor, blender cup, or small mixing bowl.

Blend or mash until the garlic is fully mixed into the mayo. A blender or food processor gives you the smoothest sauce, but you can also mash the roasted garlic with a fork and stir everything together by hand.

Taste and adjust

Taste the aioli before serving. Add more lemon juice if you want it brighter, more salt if the flavor needs to pop, or extra roasted garlic if you want a stronger garlic flavor.

Chill before serving

You can serve this lemon garlic aioli right away, but I like to chill it when I have time. Even 20 to 30 minutes in the fridge gives the garlic and lemon time to settle into the mayo.

Tips for the Best Garlic Aioli

• Start with a mayo you already like: Since mayo is the base, its flavor matters. Use one you enjoy on sandwiches or burgers.
• Use fresh lemon juice: Bottled lemon juice can taste harsh. Fresh lemon gives the aioli a cleaner, brighter flavor.
• Make the garlic the easy way: I use air fryer roasted garlic because it gives you soft, mellow garlic without the longer oven roast.
• Make it ahead: This sauce tastes even better after it chills. Make it a day or two ahead and store it covered in the refrigerator.
• Adjust it for your meal: Add extra lemon for seafood, more garlic for steak, or a pinch of Cajun seasoning if you want a little warmth.

Ways to Use Lemon Garlic Aioli

This lemon garlic aioli works anywhere you want something creamy, garlicky, and bright.

Serve it with seafood

The lemon cuts through richer bites while the roasted garlic adds depth. Try it with air fryer crab cakes, air fryer salmon patties, salmon burgers, shrimp, or pan-seared tilapia.

For another creamy seafood sauce option, use tartar sauce when you want a classic pickle-forward flavor, or Bang Bang Sauce when you want something sweet and a little spicy.

Use it as a burger or sandwich spread

Spread it on turkey burgers, ground chicken burgers, wraps, or lettuce-wrapped burgers. It adds more flavor than plain mayo while keeping the same creamy texture. It would also taste great with for salmon burgers or steak sandwiches made with leftover air fryer steak.

Pair it with vegetables

Use this aioli as a dip for roasted or air-fried vegetables. It works well with air fryer green beans, air fryer roasted cauliflower, cauliflower hash browns, baked asparagus, roasted radishes, or crispy potatoes.

Add it to chicken or steak dinners

Spoon a little over sheet pan chicken and potatoes, steak bites and potatoes, grilled chicken, or roasted chicken when you want a quick sauce to finish the meal.

Is Aioli the Same as Mayonnaise?

Traditional aioli is made by creating an emulsion. That means slowly whisking oil into garlic, and sometimes egg yolk, until it turns thick and creamy. This recipe uses mayonnaise as the shortcut base. Since mayo is already thick and creamy, you can blend it with roasted garlic and lemon juice to get the flavor of lemon garlic aioli without making the sauce from scratch.

Can I Make This Aioli Without Roasted Garlic?

Yes, but the flavor will be different. Raw garlic has a sharper bite, so start with a small amount if you use it. For the best flavor, I recommend roasted garlic because it blends smoothly into the mayo and gives the aioli a richer, softer garlic taste.

Can I Make This Vegan?

Yes. Use your favorite vegan mayonnaise in place of regular mayo. The rest of the ingredients are already plant-based.

Can I Add Other Flavors?

Yes. This lemon garlic aioli is a great base for other flavors. Try adding:

• Fresh herbs: Chives, dill, parsley, or basil.
• Spice: Cayenne, smoked paprika, Cajun seasoning, or a little sriracha.
• Extra lemon: More lemon juice or a little lemon zest for a brighter sauce.
• Dijon mustard: A small amount adds tang and depth.

How to Store Homemade Aioli

Store leftover lemon garlic aioli in an airtight container in the refrigerator. It is best after it has chilled a bit, and the flavor continues to develop as it sits.

Use a clean spoon each time you serve it and keep it cold until you are ready to use it.
