Subway Garlic Aioli Recipe: Creamy Spread With a Bold Garlic Punch

This garlic aioli delivers the same creamy richness and bold flavor you love from Subway, perfect for sandwiches or dips. I’ve simplified the process to ensure professional results every time.

With just a few ingredients and minutes of prep, you’ll have a smooth, velvety spread that elevates any dish. Store it in the fridge for up to a week—no preservatives needed.

Ingredients for Subway Garlic Aioli

Seven ingredients. Five minutes. That velvety, bold Subway-style spread is yours.

The mayo is the base, so don’t skimp—Duke’s or Hellmann’s give you that perfect creamy texture. Fresh garlic is non-negotiable here (the jarred stuff just doesn’t have the same punch). I grab mine from Trader Joe’s or the local farmers market when it’s in season. The lemon juice brightens everything up—bottled works in a pinch, but fresh is worth the squeeze.

Out of Dijon? Yellow mustard at half the amount gets you close. No fresh garlic? Garlic powder at one-quarter the amount (about 1 tsp) works, but the flavor won’t be as vibrant. If you’re watching calories, Greek yogurt for half the mayo lightens it up with a slight tang. Skip the olive oil if you’re in a hurry—the mayo’s fat keeps it smooth.

This keeps in the fridge for 5-7 days in an airtight container. The flavors meld overnight, so it tastes even better the next day. Don’t freeze it—mayo separates when thawed. Stir before using if it sits for a while.

Step-by-Step Instructions for Garlic Aioli

This simple method delivers a rich, velvety aioli with robust garlic flavor every time.

Step 1: Mince the Garlic Cloves

Start by peeling the 4 cloves Garlic Cloves. I like to smash them lightly with the flat side of my knife first—this makes peeling a breeze. Then, mince them as finely as possible. The finer the mince, the more evenly the garlic flavor will distribute throughout the aioli.

For the boldest flavor, I use fresh garlic rather than pre-minced. You should end up with about 1 tablespoon of minced garlic. If you’re short on time, you can press the garlic through a garlic press, but mincing gives you better texture control in the final product.

Step 2: Combine Wet Ingredients

In a medium bowl, whisk together the 1 cup Mayonnaise, 1 tbsp Lemon Juice, 1 tsp Dijon Mustard, and 1 tbsp Olive Oil. Use a fork or small whisk and mix until completely smooth and uniform in color.

The lemon juice and Dijon mustard add brightness and tang that balance the richness of the mayonnaise. I use full-fat mayonnaise here because it creates that luxurious, creamy texture we’re after. The olive oil adds a subtle depth of flavor that complements the garlic beautifully.

Step 3: Add Garlic and Seasonings

Add the minced garlic to the mayonnaise mixture, along with the 0.5 tsp Salt and 0.25 tsp Black Pepper. Stir everything together until the garlic is evenly distributed throughout. The mixture should look smooth with tiny flecks of garlic visible.

Here’s the thing—freshly ground black pepper makes a noticeable difference in flavor compared to pre-ground. The salt enhances all the flavors, so don’t skip it. Taste at this point and adjust the seasoning if needed, but remember the flavors will meld and intensify as it rests.

Step 4: Rest and Chill for Best Flavor

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This resting time allows the garlic flavor to mellow and infuse into the mayonnaise base. I promise it’s worth the wait—the flavors become more harmonious and the garlic loses any harsh edge.

You can make this aioli up to 3 days in advance. The longer it sits, the more the flavors develop. Just give it a good stir before serving, as the ingredients may separate slightly during storage. This aioli stays beautifully creamy and spreadable straight from the fridge.

Dietary Considerations for This subway garlic aioli

Gluten-Free Friendly

This Spread is naturally gluten-free as none of the ingredients contain wheat or gluten derivatives. Just double-check your mayonnaise and Dijon mustard labels—some brands add thickeners. I always reach for Hellmann’s or Duke’s for guaranteed safety. 💪

Vegetarian and Egg-Free

The base recipe is vegetarian but contains eggs via the mayonnaise. For an egg-free version, swap in vegan mayo like Just Mayo or Sir Kensington’s. The texture and flavor remain remarkably similar to the original.

Dairy-Free and Low-Carb

This spread is naturally dairy-free with no milk products involved. For a low-carb or keto-friendly version, simply use a sugar-free mayonnaise and ensure your Dijon mustard has no added sugars. The carb count stays minimal.

Allergen Considerations

This contains egg from the mayonnaise, so it’s not suitable for those with egg allergies. If garlic is a concern, you can reduce the amount or omit it entirely, though the flavor profile will change. Always check labels for cross-contamination warnings.

Reducing Sodium

To lower sodium, use low-sodium Dijon mustard and reduce the added salt by half. You can also try no-salt-added mayonnaise, though the flavor may taste slightly flatter. A squeeze of extra lemon juice helps brighten it up. 🍋

Long-Term Storage

This spread stays fresh in the fridge for 5-7 days in an airtight container. For longer storage, consider small batches to maintain freshness. The garlic flavor intensifies over time, so taste before serving if stored beyond 3 days.
