- 1/2 teaspoon Onion Powder
- 1/2 teaspoon Ground Oregano
- 1/2 teaspoon Cumin
For the 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)

For the Sriracha Mayo

How to Make Blackened Fish Burger and Sriracha Mayo
Step 1: Preheat the Oven
Preheat your oven to 450°F (230°C), ensuring that the rack is positioned in the middle.
Step 2: Mix Rub Ingredients
In a small bowl, combine all spice rub ingredients.
Step 3: Prepare the Fish
Take your sea bass filet and pat it dry with paper towels, leaving the skin on. Sprinkle a generous amount of the spice rub on top of the filet, saving any leftover rub for future use.
Step 4: Prepare Cabbage Slaw
In another mixing bowl, add chopped purple cabbage. Drizzle with grapeseed oil and sprinkle with kosher salt. Toss well to combine.
Step 5: Combine Sriracha Mayo Ingredients
In a small bowl, mix together mayo and sriracha. Adjust according to your desired spiciness.
Step 6: Bake Fish and Cabbage
Place the fish skin-side down on a foil-lined baking sheet. If using thinner fish fillets, place cabbage on one side immediately; if thicker, wait until there are about 4-6 minutes left of baking before adding cabbage. Bake both for approximately 4-6 minutes per half inch thickness.
Step 7: Toast Brioche Bun
Butter your brioche bun on one side and place it butter side down on the bottom oven rack for about 2-3 minutes until toasted golden brown.
Step 8: Assemble Your Burger
Once everything is cooked, remove from oven. Spread sriracha mayo generously on the bottom half of your bun. Layer with purple cabbage followed by lifting off the fish fillet from its skin using a spatula. Place fish atop cabbage and finish with arugula before topping with the bun.
Step 9: Serve Immediately
Enjoy your delicious Blackened Fish Burger topped with zesty sriracha mayo right away!
