This homemade Filet-O-Fish sandwich is an easy and satisfying way to recreate a fast food favorite at home. A crispy fish fillet is paired with melted American cheese and a creamy homemade tartar sauce, all served on a soft hamburger bun.

With just a few ingredients and a short prep time, this sandwich delivers the nostalgic flavor of the original with a fresh, homemade touch.
Why this recipe works
- Fast food flavor at home: Uses store-bought breaded fish fillets for a shortcut that still tastes authentic.

Serving suggestions
- Pair with French fries: Just like the original, this sandwich goes great with crispy fries or potato wedges.
- Add a simple slaw: A small side of coleslaw offers a cool, crunchy contrast to the warm sandwich.
- Serve with dipping sauces: Ketchup, extra tartar sauce, or lemon wedges round out the plate nicely.
- Make it a meal: Add a cold drink and a side salad for a fast food-style lunch made completely at home.

- Total Time: 30 minutes
- Yield: 2 Servings 1x
Ingredients
Scale
- 2 tablespoons mayonnaise
- 2 teaspoons sweet relish
- 2 teaspoons minced onion
- 1 pinch of salt
- 2 plain hamburger buns
- 2 frozen breaded fish squares
- 2 slices American cheese
Instructions
- In a bowl mix together mayonnaise, relish, onion and salt. Stir until well combined. Set aside.
- Cook the fish patties according to package directions, by baking in the oven or frying in a deep-fryer. For the best flavor, you will want to fry them.
- If baking the patties, add the cheese slices over the fish squares before removing from the oven to melt the cheese. If frying the patties, you can add the cheese slice on top immediately after removing it from the oil, or by microwaving the sandwich on high for about 10 seconds.
- Divide the tartar sauce and spread it evenly onto the bottom of the top half of each bun. Place the top half of the bun over the fish patty.
