This quick, modern-style mustard aioli is one of my two-minute go-to sauces - creamy, tangy, and flexible, made with good mayonnaise and your choice of mustard (Dijon is my favorite). Serve this mayo mustard sauce with chicken, pork, steak, or salmon, or with simple vegetables like asparagus and Brussels sprouts to make the whole plate feel finished.
I've made this shortcut mustard aioli for years - meaning it starts with good store-bought mayonnaise instead of making mayonnaise from scratch (traditional aioli). To build flavor, I use two kinds of mustard, lemon, and garlic. The result is a fast mayo mustard sauce that comes together in minutes and instantly finishes the dish with its creamy, tangy flavor. And you probably have what you need in the fridge.

Mustard Aioli Recipe Highlights
- Make-ahead friendly - Stir it together in minutes and refrigerate until ready to use.
- Easy and fast - No blender required, just a bowl and a spoon for a quick sauce.
- Versatile - Perfect with grilled meats, seafood, sandwiches, and vegetables, or as a quick dip or drizzle.
For a garlic confit mustard aioli, replace the raw garlic with 2 teaspoons garlic confit cloves, mashed into a paste. It's delish and easy to make.
Ingredients You'll Need
- Mayonnaise - Use a good-quality thick mayo as the base, egg-free if needed.
- Dijon mustard - Smooth, sharp, and classic; this is the main flavor driver and my go-to for a refined mustard aioli. See mustard options below.
- Whole grain mustard - Adds texture and little pops of mustard seed for a more rustic, interesting bite.
- Garlic - Fresh garlic gives the aioli backbone.
- Lemon juice - A little brightens and balances the richness.
- Dry mustard powder - A little optional insurance if your aioli gets too loose.
Please see the recipe list for measurements, salt, and pepper.
Chef's Tip: Choosing the Right Mustard. Mustard is your personality lever. One swap will completely change your mustard aioli into a fun new flavor, making it endlessly useful.
- Dijon - Smooth, sharp, and balanced. My default choice for a refined, versatile sauce.
- Whole Grain - Adds texture and little pops of flavor. Beautiful with steak or roasted vegetables.
- Spicy Brown - Slightly coarser with more warmth and bite.
- English Mustard - Very hot. A small amount goes a long way.
- Honey Mustard - Sweeter and more casual, great for dipping.
- Chinese Hot Mustard - A very sharp, fiery mustard from Chinese cuisine.
- Yellow mustard - Mild, vinegary, classic. Fine in a pinch, but it tastes more "ballpark" than "bistro."
- Flavored mustards - Such as tarragon, black currant, provencal, or green peppercorn.
Here's another terrific aioli recipe - my spicy harissa aioli, great on tacos, bowls, and salmon.
Substitutions and Variations
- Honey Mustard Aioli - Add 2 teaspoons honey then taste, add more as desired.
- Herby - Add chopped dill, chives, chervil, tarragon, or parsley (soft herbs).
- Prepared horseradish - For a sharper kick and steakhouse-style edge; a small amount goes a long way (and strain of juices).
How to Make Mustard Aioli
- Add mayo, mustards, salt, lemon juice, to a bowl.
- Add the garlic, best to use a microplane zester for a fine paste that melts in.
- Mix until it becomes a smooth mustard sauce. Refrigerate until serving.
If It's Too Loose
If the aioli feels too loose (thin), whisk in ¼ teaspoon dry mustard powder and let it sit for 5 minutes. The powder absorbs a bit of moisture and subtly tightens the texture while adding gentle bite. Add more in small increments (⅛ teaspoon at a time) so it doesn't turn sharp.
Chef's Tip: From-Scratch Mayonnaise Option
If you want to go full-scratch aioli, start with my blender homemade mayonnaise as the base. I begin the emulsion by hand, then finish in the blender while slowly drizzling in the oil for the best texture. Homemade mayo is incredible - it just doesn't keep as long in the fridge because it's made with raw egg.
Serving Suggestions
This is the kind of sauce that makes a simple plate feel finished - keep it in the fridge and you'll find excuses to use it. I often serve it with steamed salmon.
- As a dip - Serve with grilled or roasted vegetables (asparagus, green beans, broccoli, cauliflower), sweet potato fries, regular fries, or roasted baby potatoes.
- With grilled mains - Spoon alongside grilled chicken, pork chops or tenderloin, steak, salmon, bacon-wrapped scallops, shrimp skewers, or burgers.
- As a spread - On burgers, chicken sandwiches, turkey sandwiches, BLTs, or wraps instead of plain mayo.
- For boards and platters - Add to a charcuterie board with sausages, roast pork, ham, or grilled kielbasa; great with pickles and crunchy veggies.
Storage
Store Dijon mustard sauce in a covered container in the refrigerator for 3-4 days when made with store-bought mayonnaise. If using homemade mayonnaise with raw egg, use within 2-3 days and keep well chilled. USDA guidance recommends refrigerating and using preparations made with pasteurized egg products within 4 days.
As always, discard if it develops an off smell, unusual separation, or flavor changes.
Recipe FAQs
Mustard aioli is a creamy, garlic-forward sauce made by combining mayonnaise with mustard, lemon juice, and garlic. It has the tang and richness of classic aioli, with the added depth and bite of mustard.
Yes. Substitute roasted garlic or garlic confit for a milder, sweeter flavor. Use about 1-2 teaspoons mashed into a paste.
Too much lemon juice is usually the culprit, especially if your mayonnaise is on the lighter side. Start with a small amount of lemon and add more to taste. If it's already loose, whisk in a small pinch of dry mustard powder and let it sit a few minutes to thicken.
Absolutely. Dijon is classic, but whole grain adds texture, spicy brown adds warmth, and English mustard adds heat. Choose based on how bold you want the flavor. Flavored mustards (like tarragon for herbs), or black currant, are also fun.
