Cook McDonalds Fish Sandwich Copycat Like This

Step 1: Prepare the Fish
Start by rinsing the white fish fillets and patting them dry with paper towels. This will help the coating adhere better. Cut the fish into sandwich-sized portions.
Step 2: Set Up Your Breading Station
In one bowl, combine the flour, salt, and pepper. In another bowl, beat the egg. In a third bowl, place the panko breadcrumbs. This will be your breading assembly line.
Step 3: Bread the Fish
Dip each piece of fish first in the flour mixture, then in the egg, and finally coat it generously with the panko breadcrumbs. Make sure each piece is well-coated for that satisfying crunch!
Step 4: Fry the Fish
Heat your large frying pan over medium-high heat and spray with oil. Once hot, add the breaded fish pieces carefully. Fry for about 3-4 minutes on each side or until golden brown and cooked through. Remove from the pan and let them drain on paper towels.
Step 5: Make the Tartar Sauce
In a mixing bowl, combine the mayonnaise, dill pickle, parsley, capers, lemon juice, sugar, and salt. Stir until well mixed. This sauce is going to take your sandwich to the next level!
Step 6: Assemble the Sandwiches
Toast the hamburger or brioche buns lightly in the same pan or in a toaster. Spread a generous amount of tartar sauce on the bottom half of each bun. Place a piece of fried fish on top, add a slice of cheddar cheese, and finish with the top bun.
Step 7: Serve and Enjoy!
Serve your McDonalds Fish Sandwich Copycat with your favorite sides such as fries or a fresh salad. Take a bite and enjoy the crispy, creamy flavors that remind you of your favorite fast-food treat!
Low-Carb/Keto Alternatives

If you’re looking to enjoy this delicious sandwich while keeping it low-carb or keto-friendly, consider these alternatives:
- Use almond flour instead of panko breadcrumbs for a low-carb breading.
- Replace the buns with lettuce wraps for a fresh, crunchy texture.
- Opt for a slice of avocado instead of cheese for added creaminess without the carbs.
- Skip the sugar in the tartar sauce or use a sugar substitute.
Things That Go Wrong
Even the best recipes can have hiccups. Here are some common issues and how to avoid them:
- Fish falling apart: Ensure the fish is thoroughly coated and handle it gently when frying.
- Breadcrumbs not sticking: Make sure the fish is dry before breading and coat it evenly.
- Overcooked fish: Fry on medium heat and watch closely to avoid burning.
- Too greasy: Use a non-stick pan and enough oil to coat the bottom without drowning the fish.
Save It for Later
If you have leftovers (though they might be hard to resist!), here’s how to store them:
Place the leftover fish in an airtight container and refrigerate for up to 2 days. To reheat, place the fish in the oven at 350°F (175°C) for about 10 minutes to regain its crispiness. You can also store the tartar sauce separately in the fridge for up to a week.
