Instructions

1
Pat fish fillets dry with paper towels and coat with 2 tbsp of blackened seasoning, pressing with your hands to adhere the spice blend to the fish. Drizzle 1 tbsp of olive oil into the bottom of a Suvie pan and add the fillets. Place the pan in the bottom zone of your Suvie. Input settings and cook now or schedule. Bottom Zone: Bake at 400°F for 15 minutes, Top Zone: None
2
While the fish is cooking, place ½ cup of mayonnaise, 2 tbsp pickles, 1 tbsp pickle juice, 1 tbsp parsley, and 1 tsp capers in a small bowl, stirring to combine. Keep the tartar sauce refrigerated until ready to assemble the sandwiches.
3
After the cook, remove the pans from your Suvie, and spread tartar sauce over the split buns. Divide fish fillets, lettuce, tomato slices, and onion slices between the buns, then divide the sandwiches between 2 plates. Serve with lemon wedges on the side for a little citrus squeeze.

Tips & Notes

Pro tips

Pat fish fillets completely dry before coating with blackened seasoning—moisture prevents proper spice adhesion and browning.
Cook fillets over medium-high heat in a single layer without moving them for the first 3–4 minutes to develop the dark crust characteristic of blackened fish.
Toast the burger buns lightly in the same pan after cooking the fish to add texture and prevent them from becoming soggy from the tartar sauce.

Substitutions

Cod → Halibut or mahi-mahi (similar cooking time and firm texture)
Dill pickles → Bread-and-butter pickles (slightly sweeter, less sour)
Mayonnaise → Greek yogurt (tangier, lower fat version of tartar sauce)

Storage & make-ahead

Store leftover tartar sauce refrigerated up to 3 days. Assemble sandwiches fresh; refrigerate cooked fish separately and reheat gently in a 300°F oven for 5 minutes before serving.

Common Questions

What is blackened seasoning and can I make it at home?

Blackened seasoning is a Cajun spice blend typically containing paprika, cayenne, garlic powder, onion powder, thyme, and oregano. You can buy it pre-made or combine these spices in equal parts to suit your heat preference.

How do I know when the fish is cooked through?

The fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C). It should be opaque throughout with no translucent centers.

Can I use a different fish for this recipe?

Yes. Any firm white fish works well—try halibut, mahi-mahi, or sea bass. Avoid delicate fish like sole, which may fall apart during cooking.

Can I make the tartar sauce ahead of time?

Yes, prepare it up to 2 days in advance and refrigerate in an airtight container. The flavors meld and improve as it sits.

Is this recipe gluten-free?

The fish and tartar sauce are naturally gluten-free, but standard burger buns contain gluten. Use gluten-free buns to make the full sandwich gluten-free.
