Creating a silky smooth fat-free mayo at home is entirely possible with the right technique. I developed this recipe after realizing most store versions contained unnecessary additives or lacked true richness.
This version relies on aquafaba—the liquid from canned chickpeas—to create the perfect emulsion base. A touch of acidity from lemon juice or vinegar brightens the flavor while maintaining that classic mayo consistency.
What you get is a creamy, spreadable condiment that works beautifully in sandwiches, dressings, or as a base for dips. The best part? It keeps well in the fridge for up to a week.
Between you and me, even skeptics won’t believe this is oil-free. Here’s how to make it.
Ingredients for Fat Free Mayo
Eight simple ingredients transform into a rich, creamy spread without a drop of oil.
| Ingredient | Amount | Notes |
|---|---|---|
| Aquafaba 🥫 | ½ cup | From canned chickpeas, unsalted |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed preferred |
| White Vinegar 💧 | 1 tbsp | Or apple cider vinegar |
| Dijon Mustard 🟡 | 2 tsp | Smooth, not whole grain |
| Garlic Powder 🧄 | ½ tsp | For subtle depth of flavor |
| Onion Powder 🧅 | ½ tsp | Balances the acidity nicely |
| Sea Salt 🧂 | ½ tsp | Fine grain for even distribution |
| Agave Nectar 🍯 | 1 tsp | Optional for slight sweetness |
The aquafaba is everything here. Canned chickpeas from Eden Organic or Goya give the cleanest, most neutral flavor (avoid low-sodium—it lacks the body). I always keep a few cans in the pantry just for this. The lemon juice should be fresh if possible—bottled works in a pinch but fresh has that bright pop that really makes the flavor sing.
No lemon juice? White vinegar at the same amount keeps the tang. Apple cider vinegar adds a nice depth too. Out of Dijon? Yellow mustard at half the amount works, though it’s milder. The agave is optional but rounds out the sharpness—maple syrup is a good swap if that’s what you’ve got. Skip the sweeteners entirely if you prefer a tangier mayo.
This keeps beautifully in a sealed jar for up to 1 week in the fridge. Give it a good stir before using—the emulsion might separate slightly over time. Doesn’t freeze well, so make only what you’ll use. Perfect for sandwiches, dressings, or as a base for vegan aioli (just add minced garlic).

Step-by-Step Instructions for Fat Free Mayo
Here’s the method. Straightforward, tested, works every time.
Step 1: Whisk the Aquafaba to Stiff Peaks
In a clean, grease-free bowl, add the 0.5 cup Aquafaba. I recommend using the liquid from unsalted canned chickpeas for the best results. Using a hand mixer or stand mixer with the whisk attachment, beat on high speed for 3-5 minutes until stiff peaks form.
You’ll know you’ve reached the right stage when the whisk leaves a sharp peak that holds its shape. This step is crucial—it provides the structure that replaces oil in this emulsion. If your peaks aren’t stiff enough, the mixture may separate later.
Step 2: Incorporate the Acidic Components
With the mixer still running on medium speed, slowly drizzle in the 2 tbsp Lemon Juice and 1 tbsp White Vinegar. Add them gradually, about 1 tablespoon at a time, allowing each addition to fully incorporate before adding more.
This slow addition prevents the mixture from deflating. The acids help stabilize the emulsion and provide that tangy flavor characteristic of traditional mayonnaise. Watch for the mixture to thicken slightly as the liquids are absorbed.
Step 3: Add Flavorings and Sweeten
Reduce the mixer speed to low and add the 2 tsp Dijon Mustard, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, and 0.5 tsp Sea Salt. Mix until just combined, about 15-20 seconds.
Then add the 1 tsp Agave Nectar and mix for another 10 seconds. The mustard acts as an emulsifier, while the powders and salt provide depth of flavor. The agave nectar balances the acidity with a touch of sweetness.
Step 4: Adjust Consistency and Rest
Check the consistency—it should be thick but still pourable. If it’s too thick, add a teaspoon of water and mix briefly. If too thin, continue whisking for another 1-2 minutes to incorporate more air.
Transfer the mixture to a clean jar and let it rest at room temperature for 10-15 minutes. This resting period allows the flavors to meld and the emulsion to fully stabilize. The final texture should be creamy and smooth, just like traditional mayonnaise.
Store in the refrigerator for up to 1 week. The mixture may thicken slightly as it chills, which is normal. Give it a good stir before each use to restore its creamy consistency.
Pro Tips For Making Fat Free Mayo
- Chill the Aquafaba: Use it straight from the fridge—room temp aquafaba struggles to emulsify, and I learned this the hard way after three failed batches.
- Drizzle Slowly: Add your oil substitute (if using any) in a thin, steady stream while blending; dumping it all at once breaks the emulsion every time.
- Skip the Cold Vinegar: Cold vinegar can shock the mixture and cause separation, so let it sit out for 10 minutes before mixing.
- Use Fresh Lemon Juice: Bottled lemon juice lacks the brightness and acidity needed to balance the flavor—freshly squeezed makes a real difference here.
Perfect Pairings for This fat free mayo
Sandwich Spreads
This mayo transforms a simple turkey sandwich into something special. Spread 2 tbsp on whole wheat bread with sliced turkey, lettuce, and tomato. I love it with sprouted grain bread from my local Boston market for extra crunch. 🥪
Salad Dressings
Whisk 3 tbsp of this mayo with 1 tbsp lemon juice and 1 tsp honey for a creamy dressing. It coats greens beautifully without weighing them down. Try it on a simple kale salad with apples and walnuts.
Dip Base
Mix ½ cup of the mayo with 1 tbsp sriracha and 1 tsp smoked paprika for a spicy dip. Perfect for veggie sticks or baked sweet potato fries. The smokiness reminds me of summer cookouts in my triple-decker’s tiny backyard.
Vegan Deviled Eggs
Use this as the filling base for vegan deviled “eggs” made with halved white potatoes. Mix with 1 tsp turmeric for color and 1 tbsp nutritional yeast for a cheesy note. A hit at my family gatherings.
Pasta Salad Binder
Toss ½ cup of mayo with cold pasta, diced celery, and red onion for a creamy pasta salad. The acidity cuts through the richness. I add chopped dill pickles for extra tang—just like Nonna used to make.
Baking Substitute
Replace oil with this mayo in muffins or cakes for a lighter texture. Use 1:1 ratio—it adds moisture without extra fat. Works especially well in carrot cake or zucchini bread. Honestly, I was surprised how well this worked! 💡

Frequently Asked Questions
Why use aquafaba instead of eggs?
Aquafaba whips up just like egg whites but keeps it vegan and fat free. It creates the perfect stable base for the emulsion, just like traditional mayo but without cholesterol.
Can I use a different sweetener?
Yes! Swap agave for 1 tsp maple syrup or 1 tsp honey. Skip entirely if you prefer a tangier flavor. The sweetness just balances the acidity.
How long does it keep?
Stores in the fridge for up to 1 week in a sealed jar. Stir before using, as it may thicken slightly when chilled.
