Which Fish Is the Best for Sandwich?
Selecting the right fish is crucial for creating the perfect fish sandwich. The best candidates are those that hold up well during cooking and offer a clean, mild flavor that compliments a variety of toppings and sauces. Whether you’re at the fish market or the grocery store, aim for species that are known for their firm texture and ability to be seasoned and cooked to perfection without falling apart. The following are the best fishes for sandwiches:
Cod
Cod has long been a favorite for fish sandwiches due to its mild flavor and dense, flaky white flesh. It’s a versatile fish that absorbs the flavors of seasonings and marinades beautifully, making it a perfect canvas for your favorite sandwich ingredients. If you’re looking for a classic fish sandwich experience, cod is a reliable choice that won’t disappoint, whether you’re grilling, baking, or frying.
Haddock
Haddock is another excellent choice for fish sandwiches, known for its clean taste and firm white flesh. It’s slightly sweeter than cod and similarly forgiving in the kitchen, able to withstand various cooking methods without drying out. Haddock’s ability to hold together makes it ideal for stacking high with toppings and creating a sandwich that’s both filling and flavorful.
Pollock
Pollock is a slightly less common but equally delicious option for fish sandwiches. It boasts a tender texture and a mild taste, making it a great candidate for those who prefer a subtler fish flavor. Often used in fish sticks and filets, pollock can be a more economical choice without sacrificing the quality of your sandwich.
Halibut
Halibut is a premium option for a fish sandwich, offering a dense, meaty texture and a clean, sweet flavor. It’s a fish that’s less prone to flaking, allowing for a more substantial sandwich experience. Halibut’s thickness and firmness make it an excellent choice for grilling, holding its shape and offering a satisfying chew with every bite.
Tilapia
Tilapia is a widely available and affordable fish that is often recommended for those new to seafood. Its mild, almost neutral flavor makes it a blank slate for the bold flavors in your sandwich. Tilapia filets are typically thin and cook quickly, ensuring a fast and efficient meal preparation. This fish is ideal for those who enjoy a lighter sandwich that doesn’t skimp on taste.

Ingredients
- 4 fish filets (cod, haddock, pollock, halibut, or tilapia)
- 1 cup panko breadcrumbs
- 1 cup all-purpose flour
- 1 cup buttermilk
- 2 eggs, beaten
- 2 tablespoons Old Bay seasoning
- 4 brioche hamburger buns
- 4 slices American cheese
- Freshly ground black pepper
For homemade tartar sauce:
- ½ cup mayonnaise
- 2 tablespoons chopped fresh dill
- 1 teaspoon freshly squeezed lemon juice
- Pinch of onion powder
- 3 tablespoons freshly squeezed orange juice
- Cayenne pepper, to taste
- Salt and pepper, to taste
Cooking Instructions
Fish sandwiches are very easy to make, plus they are very healthy and delicious. Follow these cooking instructions to enjoy a juicy and scrumptious fish sandwich:
Cook the filets
For perfectly cooked filets, pat the fish dry before seasoning with bay seasoning to ensure the spices adhere well. After dredging in flour and buttermilk mixture, gently lay the filets in the hot oil, frying until the crust is golden and crisp. It’s important to maintain the oil at medium-high heat throughout cooking to achieve that delectable crunch without overcooking the delicate fish within.
Once fried to perfection, remove the filets from the oil and let them rest on a wire rack for about 30 minutes. This waiting period allows excess oil to drip away and the crust to set, ensuring your sandwich won’t be soggy. The result will be a filet that’s crispy on the outside, moist and flaky on the inside—ideal for building a top-notch fish sandwich.
Assemble the sandwiches
Assembling your fish sandwich is a chance to layer flavors and textures to your liking. Start with the lightly toasted buns as a sturdy base that brings a subtle buttery flavor and a satisfying crunch. Place the hot, crispy fish filet on the bottom bun, then add a slice of melty American cheese for a touch of creamy indulgence.
Generously spread the tangy tartar sauce over the top bun for a zesty kick that complements the fish’s richness. The tartar sauce not only adds flavor but also acts as a moisture barrier, keeping the bread from becoming too damp. Close the sandwich, press down gently, and you’re ready to dive into a deliciously layered fish sandwich that’s sure to be a crowd-pleaser.
Add toppings and condiments
When it comes to toppings and condiments, the world is your oyster—or in this case, your seafood of choice. Start with the classics like crisp lettuce and ripe tomatoes, then feel free to get creative. Pickled onions, coleslaw, or cucumber slices can add a refreshing crunch, while avocado lends creaminess. For a kick, throw on some jalapeños or a drizzle of hot sauce.
Don’t forget to explore the world of condiments. While tartar sauce is a staple, you might also enjoy remoulade, aioli, or even a splash of hot sauce. Each addition can transform the flavor profile of your fish sandwich, making every bite a new adventure. Experiment with different combinations to find your perfect seafood sandwich creation.

Variations and Substitutions
- For a gluten-free version, use almond flour and gluten-free panko breadcrumbs.
- Substitute the American cheese slices with pepper jack for a spicy twist or cheddar for a sharper flavor.
- Add a layer of complexity with caramelized onions or roasted red peppers.
- For an extra crunch, include pickles or crispy bacon strips.
- If you’re out of brioche buns, try ciabatta or whole-grain rolls for a different texture.
- Introduce a new dimension of heat with a sprinkle of cayenne pepper on the fish before cooking.
- In place of lemon juice, try lime juice for a tropical twist in your tartar sauce.
Storage and Reheating
When it comes to storing a classic fish sandwich, the key is keeping the crispy fish as fresh as possible. Place any remaining fish in an airtight container and store it in the refrigerator for up to two days. To handle excess moisture, line the container with paper towels before adding the fish filets. This will help absorb any condensation and keep the bread from turning soggy. For reheating, preheat the oven to 375 degrees Fahrenheit and place the fish on a baking sheet. Heat for about 10 minutes or until it’s hot throughout. This method helps maintain the crunchiness that makes these sandwiches so irresistible.
When you’re ready to assemble the sandwiches again, start by reheating the toasted brioche buns for a couple of minutes in the oven to restore their warm, soft texture. Meanwhile, repeat with remaining fish, placing them back in the oven to ensure each bite is as satisfying as the first. Avoid the microwave for reheating, as it can turn the breading soft and chewy, robbing your sandwich of its delightful texture. Remember to add a slice of cheese only after the fish is warm, allowing the residual heat to gently melt the cheese without overheating the fish.
Tips for the Best Fish Sandwich
- Season panko breadcrumbs with ¼ teaspoon salt and ¼ teaspoon pepper in a shallow bowl.
- Firmly press filets into the seasoned panko for a thick, even coating.
- Fry breaded filets in a skillet with olive oil over medium heat for about 4 minutes on each side until cooked through and crispy.
- Use soft brioche buns as a base for the sandwich, providing a light, buttery contrast to the fish crunch.
- Top with ¾ cup coleslaw, ¼ cup dill pickles, and a spoonful of tartar sauce made with 1 tablespoon Greek yogurt and 1 tablespoon sweet pickle relish.
- These toppings add layers of flavor and various textures to the sandwich.
- Serve with ice-cold potato chips or a simple side salad for a satisfying and balanced meal.
Wrap-Up!
Creating an unforgettable fish sandwich is all about the details. From selecting the right fish to perfecting the cooking process, each step is crucial. Remember to toss to coat each filet evenly in the seasoned panko breadcrumbs before frying, ensuring that every bite is encased in a crispy shell. Whether you’re serving up a quick lunch or a casual dinner, this fish sandwich recipe promises to deliver a crowd-pleasing meal that’s easy to make and even easier to enjoy.
