Arnaud’s remoulade sauce delivers that signature Cajun boldness with a velvety texture and celery crown finish—perfect for elevating seafood dishes. This traditional Louisiana sauce balances tangy mustard, briny capers, and aromatic herbs into a rich, multipurpose condiment that transforms poached shrimp or grilled fish into restaurant-quality meals.
The key lies in blending fresh ingredients with a touch of heat, creating a sauce that’s as versatile as it is flavorful.
What sets this remoulade apart is its creamy yet bright profile, achieved through a careful balance of mayo, mustard, and vinegar. The celery crown adds a distinctive texture and freshness, while smoked paprika and cayenne deliver that signature Cajun kick.
Unlike store-bought versions, this recipe lets you control the heat and tang to suit your taste—whether you prefer it mild or fiery.

For a vegan adaptation, simply swap the mayo for olive oil-based alternatives while keeping the same bold, briny essence.
The result is a sauce that’s both nostalgic and refined—bold enough to stand up to rich seafood but delicate enough to enhance delicate flavors. Whether you’re serving it with shrimp, fish, or even as a sandwich spread, Arnaud’s remoulade brings a taste of Louisiana to your table with every bite.
Ingredients for arnaud's remoulade sauce
Nine bold ingredients blend into this iconic Cajun sauce with celery crown texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥫 | ¾ cup | High-quality, full-fat preferred |
| Dijon Mustard 🌶️ | 2 tbsp | Mild or medium heat variety |
| White Wine Vinegar 🍷 | 2 tbsp | Dry, crisp vinegar preferred |
| Fresh Lemon Juice 🍋 | 1 tbsp | Freshly squeezed for brightness |
| Capers 🍃 | 2 tbsp | Chopped, briny flavor essential |
| Celery Stems 🧅 | 2 whole | Finely chopped for celery crown |
| Smoked Paprika 🌶️ | 1 tsp | For signature Cajun smokiness |
| Cayenne Pepper 🔥 | ½ tsp | Adjust for heat preference |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for fresh finish |
| Garlic Cloves 🧄 | 2 cloves | Minced, for aromatic depth |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground for texture |
The mayo sets the creamy base—Duke's or Hellmann's are my go-tos, but any full-fat brand works. Capers are non-negotiable for that briny punch; Trader Joe's has the best pre-chopped ones, but jarred works too if you drain and chop them. Celery stems should be fresh, not wilted—look for crisp, pale green stalks at the market. Smoked paprika? Penzeys or any bulk bin variety adds that authentic Louisiana smokiness. The parsley isn't just for color—it brightens the whole sauce, so grab a fresh bunch and chop extra for garnish.
No mayo? Olive oil-based vegan mayo works for a lighter version, though texture differs slightly. Short on capers? Pickle juice or a pinch of salted anchovy paste mimics the brininess (though anchovies are pescatarian-friendly). The heat level is totally customizable—skip the cayenne for mild, or add up to 1 tsp for extra kick. Dijon mustard? Yellow mustard in a pinch, but it'll be less refined. And if you're using jarred capers, rinse them well to cut excess saltiness—trust me on that one.
This sauce keeps beautifully for up to 1 week in the fridge, sealed tightly in a jar. The flavors actually meld better overnight, so make it a day ahead if you can. For meal prep, portion into small containers—perfect for shrimp dips or sandwich spreads. Freezes for up to 3 months if you're planning ahead. Pro tip: Stir in a splash of water before freezing to maintain consistency.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by this sauce because it’s just stirring—no whisking, no straining, no stress. Toss mayo, mustard, vinegar, and lemon juice in a bowl, then fold in those briny capers. Five minutes tops, and honestly? That’s all it takes to make something feel fancy.
- Tangy, Briny Magic: Between us, the capers and Dijon mustard pack a punch that’s ridiculously good—bright, sharp, with just enough creaminess to balance it. The white wine vinegar cuts through the richness, and that fresh lemon? It’s the secret to keeping this sauce from tasting heavy.
- Dips, Dresses, Glazes: This isn’t just for fish—it’s my go-to for grilled shrimp, chicken tenders, or even as a dressing for a quick potato salad. (Yes, even on a Tuesday night.) The best part? It doubles as a marinade if you’re short on time.
- Leftovers That Last: Make a big batch—it keeps for days in the fridge without separating (unlike some sauces I’ve tried). I’ll be real: I’ve had this linger for a week, and it’s still spot-on for a last-minute sandwich spread or a quick protein boost. Budget-friendly? Absolutely.
Step-by-step instructions for Arnaud's remoulade sauce
This bold Cajun sauce comes together in minutes with just a few simple steps.
Prepare the Celery Crown and Garlic Base
First, finely chop the 2 whole celery stems into tiny pieces—this creates that signature celery crown texture. I like to use the very top of the celery where the leaves meet the stem, as it's the most flavorful part. In a small bowl, combine the chopped celery with the 2 minced garlic cloves and let them sit for 5 minutes while you prepare the rest. This gives the garlic time to soften slightly and release its aroma.
While you wait, finely chop the 0.25 cup fresh parsley and set it aside. The parsley adds freshness that balances the sauce's bold flavors. You'll add it at the very end to keep its vibrant color and bright taste intact.
Whisk Together the Wet Ingredients
In a medium bowl, combine the 0.75 cup mayonnaise, 2 tablespoons Dijon mustard, 2 tablespoons white wine vinegar, and 1 tablespoon fresh lemon juice. Use a whisk to blend everything smoothly—this ensures the sauce has a consistent texture without any lumps. The mayonnaise should be at room temperature for best results, so if it's straight from the fridge, let it sit out for 10-15 minutes beforehand.
Here's the thing—don't rush this step. Whisking thoroughly now prevents the sauce from separating later. The Dijon mustard adds depth, while the white wine vinegar and lemon juice brighten the flavors and cut through the richness of the mayonnaise.
Add the Spices and Briny Elements
To the wet mixture, add the 1 teaspoon smoked paprika, 0.5 teaspoon cayenne pepper, 0.5 teaspoon sea salt, and 0.25 teaspoon black pepper. Stir well to distribute the spices evenly. The smoked paprika gives that signature Cajun smokiness, while the cayenne adds heat—adjust the cayenne to your preference if you want it milder.
Next, fold in the 2 tablespoons capers and the celery-garlic mixture you prepared earlier. The capers bring a briny punch that ties everything together. Stir gently to combine, being careful not to overmix—you want to preserve the texture of the celery crown. If the sauce looks too thick, add 1 teaspoon water at a time until it reaches a smooth, spreadable consistency.
Finish with Fresh Parsley and Rest
Finally, gently fold in the 0.25 cup chopped fresh parsley. This adds a pop of color and freshness that balances the sauce's bold flavors. Give everything one last stir to ensure the parsley is evenly distributed. The sauce is now ready to use, but here's the secret: let it rest for 15-20 minutes in the refrigerator before serving. This allows the flavors to meld together perfectly.
Real talk: if you can't wait, go ahead and use it immediately, but that short rest time makes a noticeable difference in flavor development. Once rested, taste and adjust the seasoning if needed—you might want a touch more salt or a splash of lemon juice to brighten it up.
Pro Tips For Making Arnaud'S Remoulade Sauce
- Whisk the mustard first: I learned this the hard way—adding Dijon straight to mayo clumps it like cement. Mix the mustard with 1 teaspoon of warm water or vinegar first until smooth, then fold in the mayo. This keeps your sauce silky, not lumpy.
- Drain capers properly: Rinsing capers in a fine-mesh strainer removes the brine but leaves them soggy. After draining, pat them dry with a paper towel—this prevents dilution and keeps the sauce bright, not watery.
- Balance acid gradually: Start with half the lemon juice and vinegar called for. Taste after mixing, then add the rest. Overdoing it turns your sauce sharp; underdoing it leaves it flat. Adjust in ½-teaspoon increments.
- Use room-temp mayo: Cold mayo thickens remoulade into a paste. Let store-bought jars sit 10 minutes at room temp before mixing—this guarantees a smooth, spreadable texture. (Yes, even if you’re impatient like me.)
Health benefits of this arnaud's remoulade sauce
Heart Health Boost
This remoulade sauce delivers a surprising heart-healthy punch thanks to its omega-3 rich ingredients. The olive oil-based mayo (or traditional mayo) provides monounsaturated fats, which support cholesterol balance, while capers contribute antioxidant-rich compounds that combat inflammation.
The celery crown adds fiber and potassium, both essential for heart function. 💪
Digestive Benefits
The fresh parsley and lemon juice in this sauce pack a digestive-friendly combo. Parsley contains apigenin, a compound that may reduce bloating, while lemon juice aids stomach acid production for better digestion. The Dijon mustard also stimulates digestion—just be mindful of portion sizes if you have sensitive stomachs.
Antioxidant Powerhouse
This sauce is loaded with antioxidant-rich ingredients that fight oxidative stress. The smoked paprika provides vitamin E and carotenoids, while fresh parsley delivers vitamin C and chlorophyll.
Even the garlic contributes allicin, a compound with potent anti-inflammatory properties. Think of it as a flavorful way to sneak in nutrients! 🌿
Low-Calorie Option
For a lighter version, swap mayo for Greek yogurt or vegan mayo (like Sir Kensington's) to cut calories while keeping the creamy texture. The vinegar and lemon juice add tang without extra fat, making this sauce a smart choice for those watching their calorie intake.
Just watch the capers—they pack a salty punch that can sneak up on you!
Protein-Packed Pairing
When served with grilled shrimp or fish, this sauce becomes a protein-powerhouse combo. Seafood provides lean protein and omega-3s, while the remoulade adds flavor without excess calories. It's a perfect match for pescatarian diets or anyone looking to boost their protein intake with minimal effort.
The celery crown even adds a subtle crunch that keeps things interesting. 🦞

Frequently asked questions
What makes this remoulade sauce different from other Cajun sauces?
The signature celery crown texture and balanced heat set this apart. Unlike creamy Cajun mayos, this sauce incorporates finely chopped celery stems for a subtle crunch and fresh parsley for brightness. The smoked paprika and cayenne provide authentic Cajun heat without overpowering the briny capers and tangy vinegar. It's the perfect bridge between bold and refined flavors!
Can I make this sauce without mayo for a lighter version?
Swap the mayo for Greek yogurt or vegan mayo to cut calories while keeping the creamy texture. For extra richness, blend 1/4 cup olive oil with the wet ingredients. The sauce will be lighter but still packed with flavor. Just reduce the vinegar slightly to balance the oil's richness.
How do I adjust the heat level in this sauce?
Start with the 0.5 tsp cayenne pepper as written, then taste before serving. For milder heat, reduce to 1/4 tsp or omit entirely. If you love spice, add up to 1 tsp extra cayenne or a pinch of red pepper flakes. The smoked paprika adds depth without heat, so don't adjust that unless you're avoiding smoke flavor entirely.
What's the best way to store and reheat this sauce?
Store in an airtight container in the fridge for up to 1 week. The flavors actually improve overnight! To reheat, gently warm in a saucepan over low heat with 1-2 tsp water to restore creaminess. Never microwave—it can break the sauce's texture. For meal prep, portion into small containers to use as dips or spreads.
Can I use jarred capers instead of fresh?
Yes, but rinse them well first to remove excess salt. Drain completely and chop them finely to mimic the texture of fresh capers. For extra brininess, add 1/2 tsp additional salt to the sauce. Jarred capers work perfectly—they just need proper preparation to avoid over-salting your remoulade.
