This seasonal Wendy’s Fish Sandwich has people lining up for its perfectly golden, crispy Wild-Caught Alaskan Pollock, that creamy dill tartar sauce, and those fresh toppings that make it oh-so-satisfying.

How to make Wendy’s Fish Sandwich

Wendy’s Fish Sandwich is a seasonal fast-food menu item offered by the U.S. chain Wendy’s—typically available around the Lenten season (the weeks leading up to Easter) or as a limited-time special.

Ingredients

For the Fish

• 2 Wild-Caught Alaskan Pollock fillets (or substitute with cod or tilapia)
• 1 cup panko breadcrumbs (for the crispy texture)
• 2 tbsp all-purpose flour (for coating)
• 1 egg, beaten
• 1/4 tsp garlic powder
• 1/4 tsp paprika (optional, for added flavor)
• Salt and pepper, to taste
• Vegetable oil (or canola oil, for frying)

For the Sandwich

• 2 split-top brioche buns or hamburger buns
• 2-3 lettuce leaves (romaine or iceberg)
• 2 slices of American cheese
• 4-6 dill pickle slices

For the Creamy Dill Tartar Sauce

• 1/2 cup mayonnaise
• 2 tbsp dill pickles, finely chopped
• 1 tsp lemon juice
• 1 tsp Dijon mustard
• 1/2 tsp dried dill or 1 tsp fresh dill
• Salt and pepper to taste

Instructions

Step 1: Prepare the Tartar Sauce

1. In a small bowl, combine mayonnaise, finely chopped dill pickles, lemon juice, Dijon mustard, and dried dill.
2. Add a pinch of salt and pepper to taste, then mix well until combined.
3. Cover the bowl and refrigerate until ready to assemble the sandwiches. This helps the flavors meld together.

Step 2: Prepare and Fry the Fish

Set up your breading station:

1. In one shallow bowl, combine panko breadcrumbs, garlic powder, paprika, and a pinch of salt and pepper.
2. In a second bowl, add beaten egg.
3. In a third bowl, place the flour for dredging.

Coat the fillets:

1. Lightly pat the Pollock fillets dry with a paper towel.
2. Dredge each fillet in flour, making sure to coat evenly on all sides.
3. Dip the fillets into the egg mixture, ensuring they’re fully coated.
4. Press the fillets into the panko mixture, turning to coat all sides evenly. Press gently to ensure the breadcrumbs adhere well.

Fry the fish:

1. Heat about an inch of vegetable oil in a large skillet or frying pan over medium-high heat. To test the oil, drop a breadcrumb into the oil; it should sizzle and float to the top.
2. Carefully place the breaded fish fillets into the hot oil. Avoid overcrowding the pan to maintain the temperature of the oil.
3. Cook for 3-4 minutes on each side, or until the fillets are golden brown and crispy. The internal temperature of the fish should reach 145°F (63°C).
4. Once cooked, transfer the fillets to a plate lined with paper towels to drain excess oil.

Step 3: Assemble the Sandwich

1. Toast the bun: If desired, lightly butter and toast the split-top brioche buns in a skillet or on a griddle until golden brown.
2. Spread a generous amount of tartar sauce on both halves of the bun.
3. Place a piece of lettuce on the bottom bun, followed by the crispy fish fillet.
4. Place a slice of American cheese on top of the fish (you can let it melt slightly for extra indulgence).
5. Add 2-3 pickle slices on top of the fish, then place the top bun on to complete the sandwich.

Tips for the Perfect Wendy’s Fish Sandwich

• Use Alaskan Pollock for Authenticity: While you can substitute other white fish like cod or tilapia, Alaskan Pollock is what Wendy’s uses, and it’s known for its mild flavor and flaky texture.
• Don’t Skip the Panko: Regular breadcrumbs won’t give you that distinct crunchy coating. Panko breadcrumbs are the secret to a light and crispy exterior.
• Keep the Oil Hot: Maintaining the right oil temperature (around 350°F) is key to achieving a golden, crispy crust without making the fish greasy. A cooking thermometer can help with this.
• Refrigerate the Tartar Sauce for at least 30 minutes to enhance its flavor. If you’re a fan of a tangier sauce, feel free to add a bit more lemon juice.
• Customize Your Toppings: While American cheese, lettuce, and pickles are signature toppings for Wendy’s version, don’t hesitate to add tomato slices, coleslaw, or even a drizzle of hot sauce for a personalized twist.

Ingredients Substitutes

While the original Wendy’s Fish Sandwich recipe has its signature ingredients, you might not have all of them on hand—or perhaps you’re looking for alternatives to suit dietary needs, preferences, or simply creativity.

1. Substitutes for the Fish

The star of Wendy’s Fish Sandwich is Wild-Caught Alaskan Pollock, known for its mild flavor and flaky texture. If Pollock isn’t available, try these alternatives:

Fish Substitute Options:

• Cod: A mild, white fish that is flaky and tender, making it the closest substitute for Pollock. Perfect for frying and holds up well in sandwiches.
• Tilapia: Mild-tasting, slightly firmer than Pollock but still flaky when cooked. A budget-friendly substitute.
• Haddock: Similar in taste and texture to Pollock, haddock has a slightly stronger flavor but still works beautifully for a fried Wendy’s Fish Sandwich.
• Swai: A more affordable, mild-tasting white fish that’s softer than Pollock but fries well in crispy coatings.
• Catfish: A Southern-style alternative with a slightly richer, more distinct flavor; great for those who want a little more personality in the Wendy’s Fish Sandwich.

Non-Fish Options:

If you’re looking to avoid meat or seafood altogether:

• Tofu: Firm tofu slices can be breaded and fried to replicate the crispy texture of fried fish. Pre-marinate tofu in lemon juice and Old Bay seasoning for added flavor.
• Jackfruit: Certain preparations of young jackfruit can mimic a flaky texture. Coat it in batter and panko for a similar feel.
• Vegan Fish Fillets: Many brands (like Gardein or Quorn) make plant-based fish substitutes that fry up golden and crispy.

2. Substitutes for Panko Breadcrumbs

Panko breadcrumbs help achieve that signature crunchy texture, but there are other options if panko is unavailable.

Panko Substitutes:

• Regular Breadcrumbs: Though not as airy or crisp, standard breadcrumbs can be used. Opt for unseasoned ones if you’re adding your own spices.
• Crushed Cornflakes: Cornflakes create a similar crunchy texture and add a slight sweetness. Just crush them finely before using.
• Crushed Crackers: Saltine or Ritz crackers can be crushed and used for coating. Be cautious with salty crackers and season accordingly.
• Matzo Meal: Common in Jewish cooking, this fine breading works well for coatings.
• Ground Nuts or Seeds: For a gluten-free option, finely ground almonds, sunflower seeds, or even crushed potato chips can add flavor and crunch.
• Gluten-Free Breadcrumbs: Many stores carry gluten-free panko substitutes that work seamlessly in fried recipes.

3. Substitutes for All-Purpose Flour

Flour is used for dredging the fish before breading, as it helps the coating adhere to the surface. Here are alternatives:

Flour Substitutes:

• Cornstarch: Perfect for dredging and gives an extra-crispy result.
• Rice Flour: Ideal for a gluten-free option and ensures light, crispy breading.
• Almond Flour: For a low-carb alternative, it’s great, though slightly denser.
• Chickpea Flour: Adds a nutty flavor and works well for fried dishes.
• Potato Starch: A gluten-free choice, often used in Asian-style frying recipes for extra crunch.

4. Substitutes for Egg (Binding Agent)

Eggs are used to bind the breadcrumbs to the fish, but you can easily replace them if you’re out of eggs or need an allergy-friendly option.

Egg Substitutes:

• Milk or Buttermilk: Dip the fish in milk before coating. Buttermilk adds tangy richness.
• Plant-Based Milk: Unsweetened almond milk, soy milk, or oat milk can act as liquid binders.
• Mayonnaise: A thin layer of mayo on the fish helps breadcrumbs stick, adding extra flavor.
• Aquafaba (Chickpea Water): Whisk the liquid from a can of chickpeas; it mimics egg consistency and binds effectively.
• Flaxseed Meal: Mix 1 tbsp flaxseed meal with 2.5 tbsp water for a plant-based binder.
• Yogurt: Plain regular or vegan yogurt thinned with water can bind coatings.

5. Substitutes for Brioche Bun

Wendy’s uses a soft, buttery split-top brioche bun for their sandwich, but several alternatives work just as well depending on preference or availability.

Bun Substitutes:

• Hamburger Buns: A versatile alternative, especially if you choose soft, slightly sweet ones.
• Potato Buns: These are soft and pillowy, much like brioche buns, with a slightly buttery flavor profile.
• Ciabatta Rolls: For a crustier bread option, ciabatta works for a rustic twist.
• Hawaiian Sweet Rolls: For a sweeter pairing, Hawaiian rolls add extra flavor and softness.
• Gluten-Free Buns: Widely available for those with gluten sensitivities.
• Lettuce Wraps: Opt for crisp romaine or iceberg lettuce leaves if you prefer a bun alternative or want a lighter, low-carb swap.

6. Substitutes for American Cheese

American cheese is creamy and melts quickly, making it a perfect addition to the sandwich. However, you can swap it for other cheeses that pair well with fish.

Cheese Substitutes:

• Provolone: Mild and creamy, with a slight nuttiness. A great alternative.
• Swiss Cheese: Offers a slightly tangy flavor that complements the fish well.
• Cheddar Cheese: Sharp and bold; adds more flavor to the sandwich.
• Mozzarella: Creamy and stretchy; perfect for those who love melty cheese.
• Plant-Based Cheese: Brands like Daiya or Violife offer dairy-free slices that mimic the flavor and meltability of American cheese.

7. Substitutes for Dill Pickles

Pickles add a tangy crunch that complements the creamy tartar sauce and crispy fish. If ditching dill pickles, try these alternatives:

Pickle Substitutes:

• Sweet Pickles (Bread and Butter Pickles): For a sweeter crunch.
• Pickled Jalapeños: Add a kick of spice for those who like heat.
• Pickled Onions: Mildly sour and crisp; balances the flavors well.
• Capers (in Tartar Sauce): Boost the tangy flavor with these briny morsels.
• Fresh Cucumber Slices: Raw cucumber provides a crunch if pickles are unavailable.

Final Thoughts

These side dishes not only complement Wendy’s Fish Sandwich in flavor but also turn it into a complete, restaurant-worthy meal. Depending on your mood, you can keep things light and fresh or go all out with indulgent sides.
