Samurai Sauce (Belgian Spicy Mayo)

I’m always looking for bold, globally-loved sauces that make everyday food exciting, and this Belgian-style spicy mayo is one I can’t stop putting on fries, burgers, and wraps. It's called Samurai Sauce, and it's perfect for the spicy food lover.

It is ridiculously easy to make in minutes with simple ingredients, and I think it is poised to go worldwide. I'm happy to spread the word.

What is Samurai Sauce?

Samurai Sauce is a creamy, spicy mayo-based condiment popular in Belgian and French fry shops, as well as many kebab shops across Europe. It is typically made with mayonnaise, ketchup, and a chili paste for heat, most often sambal oelek or sometimes harissa paste.

Think of it as a spicy fry sauce with more bold chili flavor. It is tangy, a little sweet, and easily customizable, making it perfect for fries, burgers, sandwiches, wraps, and grilled meats.

Let me show you how to make it at home.

Samurai Sauce Ingredients

• Mayonnaise. Use your favorite brand.
• Sambal Oelek. Or use harissa.
• Ketchup. Try my spicy ketchup recipe for extra kick.
• Dijon Mustard. It's also good with a Creole mustard or my spicy mustard recipe.
• Rice Vinegar. Or use white vinegar or lemon juice.
• Sugar. Or honey. Optional, to round out the spicy edges.
• Garlic Powder. Or freshly minced.
• Salt. To taste.

The full ingredients list with measurements is listed in the printable recipe card at the bottom of the post.

How to Make Samurai Sauce

1. Add all of the ingredients to a mixing bowl. Whisk until smooth.
2. Taste and adjust for heat, sweetness, and tang.
3. Cover and refrigerate at least 30 minutes to let the flavors meld.

Serving Ideas

Samurai Sauce is most commonly served in Belgium with fries (frites) as a dipping sauce, often from fry shops and snack stands. That classic pairing is the best place to start.

It is also great with:

• Burgers and smash burgers
• Fried chicken wings
• Chicken sandwiches and wraps
• Kofta kebabs, gyros, and grilled sausages
• Roasted potatoes, potato wedges, or baked Cajun fries
• Chicken tenders, onion rings, crispy fried jalapeno bottlecaps, and other crispy snacks
• Grilled meats like grilled chicken, pork, or steak

Use it anywhere you’d use a spicy mayo or fry sauce. It adds creamy heat, tang, and big flavor fast.

Storage

Store Samurai Sauce in an airtight container in the refrigerator. It will keep about 5 to 7 days.

For best freshness, give it a quick stir before serving, especially after it has been chilled for a day or two. Do not leave it out at room temperature for long, since it is mayo-based.
