What is Blackened Fish and Why Is It So Delicious?
Blackening is a cooking technique originating from Cajun cuisine, famously popularized by chef Paul Prudhomme. It involves dipping fish fillets (or other meats) in melted butter, then coating them generously with a blend of herbs and spices before cooking them in a scorching-hot, cast-iron skillet. The intense heat sears the exterior, creating a dark, crispy crust while locking in the moisture and flavor of the fish. The result is a wonderfully spicy, smoky, and incredibly tender fillet that’s bursting with character. Our oven-baked approach makes it even easier to achieve that perfect blackened crust without the smoky mess of a stovetop.
Perfect Pairings: What Complements a Blackened Fish Burger?
The bold flavors of blackened fish call for equally robust and complementary side dishes. When serving your Blackened Fish Burger, consider a variety of options that balance its spiciness and richness:
- **Smoked Baked Beans:** The smoky sweetness of baked beans offers a comforting contrast to the spicy fish, making for a hearty, satisfying meal.
- **Creamy Potato Salad:** A classic potato salad, especially one with a tangy dressing, provides a cool and creamy element that soothes the palate and adds a refreshing texture.
- **Macaroni and Cheese:** For a true Southern-inspired experience, a rich and gooey macaroni and cheese is an irresistible choice that brings comfort and indulgence.
- **Collard Greens:** These savory, often slow-cooked greens offer a slight bitterness and earthy depth that beautifully complements Cajun-influenced dishes, adding a touch of traditional flavor.
- **Crisp Coleslaw:** A vibrant coleslaw with a creamy or vinegar-based dressing can add a refreshing crunch and tangy counterpoint, cutting through the richness of the burger.
- **Corn on the Cob or Roasted Corn Salad:** Sweet corn provides a lovely sweetness that pairs exceptionally well with spicy flavors, whether served simply on the cob or in a vibrant salad.
- **Sweet Potato Fries:** The natural sweetness and crispy texture of sweet potato fries offer a delicious alternative to regular fries and stand up well to the burger’s bold profile.
- **Simple Green Salad with Citrus Vinaigrette:** For a lighter option, a fresh green salad with a bright, zesty dressing can cleanse the palate and add a healthy balance to your meal.
Don’t be afraid to experiment with your favorite sides! The versatility of this blackened fish burger means it pairs well with a wide range of accompaniments, allowing you to tailor your meal to your preferences.

Why Choose a Fish Burger Over Traditional Options?
We all love a good burger, whether it’s beef, turkey, or black bean. Burgers are familiar, comforting, and generally unintimidating for weeknight dinners. But have you ever considered the incredible potential of a fish burger? It’s a delightful cross between a classic fish sandwich and a gourmet burger, offering a lighter, often healthier alternative without sacrificing flavor or satisfaction.
This recipe transforms a beautiful piece of fish, such as sea bass, into the star of your meal. Baked to perfection in the oven alongside vibrant purple cabbage, it’s then nestled in a soft brioche bun and generously topped with a customizable sriracha mayo. The beauty of this dish lies in its simplicity: the fish and cabbage cook together on a single baking sheet, and the buns toast right in the oven. A quick mix of mayo and sriracha, and dinner is effortlessly served!

Navigating Fish Consumption During Pregnancy: What You Need to Know
If you’re pregnant or breastfeeding and wondering about the safety of eating fish, you’re certainly not alone. There’s been a lot of conflicting information over the years, making it difficult to know what to believe. On one hand, fish is celebrated for being heart-healthy and packed with essential nutrients like DHA, crucial for baby’s development. On the other hand, concerns about mercury and PCBs (polychlorinated biphenyls) can make many expectant mothers hesitant.
The good news is that the consensus from leading health organizations, including the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA), is clear: eating the right types and amounts of fish is not only safe but highly recommended for both you and your baby’s health. In fact, these groups have released joint statements actively encouraging pregnant and breastfeeding women to incorporate more pregnancy-safe fish into their diets.
Their recommendations suggest consuming **8 to 12 ounces (two to three servings) of low-mercury fish every week.** This guideline helps ensure you get the beneficial omega-3 fatty acids and other nutrients without excessive exposure to contaminants.
Despite the often-publicized list of fish to limit, the vast majority of fish available in stores and restaurants are considered safe to eat when you’re expecting, within the recommended two to three servings (8 to 12 ounces) per week. Safe choices include:
- Wild Salmon
- Shrimp
- Catfish
- Tilapia
- Sole
- Flounder
- Haddock
- Halibut
- Ocean Perch
- Pollock
- Cod
- Canned Light Tuna (limit albacore/white tuna)
- Crab
- Crawfish
- Lobster
- Hake
- Clams
- Black Sea Bass (featured in this recipe!)
- Anchovies
- Trout
Always opt for a variety of these low-mercury options to maximize your nutrient intake and minimize potential risks. If you have specific dietary concerns, consulting with your healthcare provider is always the best course of action.

I told you this was easy! And not only easy, but incredibly versatile. You can choose almost any firm white fish for this recipe, adjusting the cooking time slightly based on thickness. The sriracha mayo is also fully customizable – make it as mild or as spicy as your heart desires. It’s truly a recipe designed for your convenience and taste.

Blackened Fish Burger + Sriracha Mayo Recipe
Blackened Fish Burger and Sriracha Mayo

This **Blackened Fish Burger + Sriracha Mayo** is a quick and easy weeknight meal that is healthy and bursting with flavor! Ready and on your table in **30 minutes**!
Ingredients
Rub
- 1/4 teaspoon Cayenne Pepper
- 1/2 teaspoon Ground Black Pepper
- 1 teaspoon Smoked Paprika
- 1 teaspoon Kosher Salt
- 1/2 teaspoon Garlic Powder
- 1/2 teaspoon Onion Powder
- 1/2 teaspoon Ground Oregano
- 1/2 teaspoon Cumin
Fish Burger:
- 4-6 Ounces Sea Bass Filet, or other firm fish
- 1/2 – 3/4 Cup Chopped Purple Cabbage
- 1 Tablespoon Grapeseed Oil, extra virgin olive oil will also work
- 2 teaspoon Kosher Salt
- 1/4 Cup Arugula
- 1 Brioche Bun, or any other type of hamburger bun you have
Sriracha Mayo
- 3 Tablespoons Mayo
- 1/2 Tablespoon Sriracha
Instructions
- Preheat oven to 450°F (230°C) and ensure the oven rack is in the middle.
- Combine all Rub ingredients in a small bowl.
- Pat the sea bass fillet dry with a paper towel, leaving the skin on. Sprinkle a generous amount (about 1-2 teaspoons) of the rub over the top of the fillet. Save any remaining rub for future use.
- In a small mixing bowl, toss the chopped purple cabbage with grapeseed oil and kosher salt until well combined.
- Mix the sriracha and mayo together in a separate bowl. Taste and adjust sriracha to achieve your desired level of spiciness.
- Prepare a foil-lined baking sheet. Place the fish fillet, skin-side down, on one side of the baking sheet. If your fish is thin (approximately 1/2 inch thick), add the cabbage to the other side of the baking sheet immediately. If your fish is thicker, wait until the last 4-6 minutes of cooking to add the cabbage.
- Butter the brioche bun halves and place them butter-side down on the bottom oven rack for approximately 2-3 minutes during the fish’s cooking time, or until lightly toasted.
- Bake the fish for 4-6 minutes per 1/2 inch of thickness, or until it flakes easily with a fork.
- Remove the fish, cabbage, and bun from the oven.
- Spread the desired amount of sriracha mayo on the bottom half of the toasted bun.
- Layer the cooked purple cabbage on top of the sriracha mayo.
- Using a spatula, gently lift the fish fillet off its skin (which should stick to the foil) and place it on top of the cabbage.
- Add fresh arugula on top of the fish, then complete your burger with the top half of the bun.
- Serve immediately and enjoy your delicious Blackened Fish Burger!
Recipe Notes
- **Rub Customization:** This homemade rub is fantastic, but you can easily substitute it with your favorite store-bought Creole seasoning or other pre-packaged blackened seasoning for convenience.
- **Fish Choice:** While sea bass is recommended for its firm texture that holds up well as a “burger,” feel free to experiment with other firm white fish varieties like cod, snapper, grouper, or mahi-mahi. Adjust cooking times as needed based on thickness.
- **Sriracha Mayo Heat Level:** If you’re cautious about spiciness, start with just 1 teaspoon of sriracha in your mayo. Mix, taste, and gradually add more in 1/2 teaspoon increments until you achieve your preferred level of heat. For an extra kick, consider adding a dash of hot sauce directly to your fish rub!
- **Storage:** Cooked fish burgers are best enjoyed fresh. However, if you have leftovers, the cooked fish can be stored separately in an airtight container in the refrigerator for 3-4 days. Reheat gently to prevent drying out.
- **Alternative Toppings:** Beyond arugula and cabbage, consider adding sliced tomatoes, pickles, red onion, or even a slice of avocado for extra creaminess and freshness.
