Salmon (1-½ lbs, skin removed): The star protein—rich, flaky, and full of healthy oils that hold up well to bold seasoning.
Kosher salt: Essential for seasoning to bring out the natural flavor of the salmon and balance the spices.
Fresh cracked pepper: Adds a subtle heat and aromatic fragrance that complements the Cajun seasoning.
Cajun seasoning: A blend of spices that infuses the salmon with classic Louisiana flair.
Old Bay seafood seasoning: Adds complexity and a hint of umami seafood flavor, elevating the salmon even further.
Arugula leaves: Peppery greens that give a fresh, slightly bitter crunch to offset the richness of the fish and sauce.
Slider buns: Soft, tender buns that perfectly cradle all the ingredients without overpowering them.
Alexia Brand Onion Rings (1 per slider): Crispy and sweet, these add an irresistible crunch and textural contrast.
Mayonnaise (1 cup): The creamy base for the remoulade sauce bringing smoothness and richness.
Finely chopped green onion (¼ cup): Adds a fresh, sharp bite to the sauce.
Chopped garlic (2 tsp): Gives depth and a touch of pungency to the remoulade.
Prepared horseradish (1 Tbs): Kicks up the heat with a lively bite.
German whole-grain mustard (2 Tbs): Offers tang and lovely texture with visible seeds.
Yellow mustard (3 tsp): Adds classic mustard tang for balance.
Ketchup (3 Tbs): Sweetness and acidity round out the remoulade flavors.
Hot sauce (1 tsp): Provides a subtle smoky heat.
Worcestershire sauce (1 tsp): Rounds out umami, adding savory complexity.
Pinch kosher salt, ½ tsp cayenne pepper, ½ tsp Cajun seasoning: These small touches intensify the remoulade’s spice and seasoning.

Finely diced fresh jalapeno (1 tsp): Adds a bit of fresh heat and crunch inside the remoulade.

How to Make Cajun Salmon Sliders with Remoulade Recipe

A clear glass bowl sits on a white marbled surface, filled with multiple layers of different ingredients. Starting from the top, there is a rough layer of chopped fresh green herbs, likely parsley and green onions. Below this, there is a creamy white layer with dollops of yellow mustard and a bit of grainy brown mustard sauce on the right side. To the left, there's a thick red layer of ketchup, and closer to the center, a mound of minced pale beige garlic or ginger. Spread around the center is a white creamy base, sprinkled generously with reddish-brown paprika powder. The textures range from smooth and creamy to finely chopped fresh elements, all grouped separately but closely inside the bowl.

Step 1: Make the Remoulade Sauce

Start by combining all the remoulade ingredients in a bowl: mayonnaise, green onion, garlic, horseradish, both mustards, ketchup, hot sauce, Worcestershire sauce, salt, cayenne, Cajun seasoning, cilantro, and jalapeno. Mix thoroughly until smooth and well blended. Then, pop it into the fridge to chill for at least 30 minutes. This resting time lets the flavors mingle and deepen, giving you a luscious sauce that packs a punch while complementing the salmon perfectly.

Step 2: Prepare and Season the Salmon

Preheat your oven to 400°F. Cut the skinless salmon into square portions that will fit neatly on your slider buns. Season each piece generously with kosher salt, fresh cracked pepper, Old Bay seasoning, and Cajun seasoning, ensuring each bite will be bursting with flavor. Place the salmon pieces on a rack set inside a rimmed baking sheet to allow even cooking and moisture to escape.

Step 3: Bake the Salmon and Onion Rings

Place the baking sheet with the seasoned salmon and the package of Alexia Brand onion rings in the oven. Bake the salmon for about 10 minutes or until just cooked through and flaky. The onion rings should be baked according to their package instructions simultaneously, so you’ll have both elements perfectly hot and crispy at the same time.

Step 4: Assemble the Sliders

Once your salmon and onion rings are ready, it’s time to build these beauties. Spread some of the chilled remoulade sauce on the bottom slider bun, then layer with fresh arugula leaves for a peppery crunch. Add a juicy piece of the baked salmon, a generous dollop of remoulade, and top it with a crispy onion ring. Before placing the top bun, spread a little more remoulade on it to help hold everything together, adding that saucy goodness with every bite.

Garnishes

Fresh cilantro leaves, extra diced jalapenos, or a squeeze of lime juice on top of the sliders add brightness and an extra hint of herbal freshness. A sprinkle of smoked paprika or additional Cajun seasoning can also enhance the visual appeal and flavor, inviting your guests to dive in with their eyes and taste buds.

Side Dishes

These sliders pair wonderfully with cool, crisp sides like a simple mixed greens salad, tangy coleslaw, or even roasted sweet potato fries. The freshness of the sides contrasts beautifully with the rich and spicy flavors of the salmon sliders, creating a well-rounded meal perfect for any occasion.

Creative Ways to Present

For a fun party platter, serve a row of these sliders with mini dipping bowls of extra remoulade sauce and a variety of pickled vegetables on the side. Wrapping each slider in parchment paper tied with kitchen twine adds a rustic yet charming touch, perfect for casual open-house events or picnics.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, store the sliders disassembled in airtight containers in the refrigerator. Keep the salmon, remoulade sauce, and onion rings separate to maintain their textures. This way, your sliders will stay fresh and enjoyable for up to two days.

Freezing

It’s best not to freeze fully assembled sliders, as the buns can become soggy and the onion rings lose their crunch. However, you can freeze the seasoned, raw salmon portions tightly wrapped on a tray to keep their freshness for up to one month. Thaw overnight before baking.

Reheating

When ready to enjoy leftovers, gently reheat the salmon in a preheated 350°F oven for about 5-7 minutes to warm through without drying it out. Warm the onion rings separately in a toaster oven to keep them crispy. Avoid microwaving to maintain the texture and flavors of your Cajun Salmon Sliders with Remoulade Recipe.

FAQs

Can I use other types of fish instead of salmon?

Absolutely! While salmon is excellent for its richness and texture, you can substitute with other firm, flaky fish like cod or halibut. Just be sure to adjust cooking times accordingly to avoid overcooking.

Is the remoulade sauce very spicy?

The remoulade delivers a balanced kick with a nice blend of heat from the horseradish, cayenne, and jalapeno but isn’t overwhelmingly spicy. You can always adjust the amounts of hot sauce or jalapeno to suit your heat preference.

Can I make the sliders gluten-free?

Certainly! Swap the regular slider buns for gluten-free ones, and check the ingredients on your Cajun seasoning and onion rings to ensure they are gluten-free. You can also substitute onion rings with gluten-free crispy alternatives or omit them if preferred.

How do I get the salmon perfectly cooked?

Baking at 400°F for about 10 minutes usually yields a tender, flaky salmon that’s cooked through but still juicy. Watch closely to avoid overcooking; the salmon should flake easily but remain moist.

What’s the secret to crispy onion rings in this recipe?

Following the package instructions for baking is key, but giving your oven a good preheat and avoiding overcrowding the pan ensures even cooking. For extra crispiness, consider a quick broil for the last minute, but keep a close eye to prevent burning.
