Why Make a Copycat Filet-O-Fish at Home?

I know what you’re thinking: “Why bother making it at home when I can get it in 5 minutes at McDonald’s?” Here’s why:

  1. Quality Control: When you make it at home, you choose the ingredients. Fresh cod, real cheese, and a tartar sauce you can actually pronounce—no mystery additives here.
  2. Flavor Upgrade: While the original is great, a homemade version gives you the freedom to tweak the flavors to your liking.
  3. Satisfying Experience: There’s something incredibly rewarding about replicating a beloved restaurant dish. It’s like mastering a secret recipe!
  4. Cost Savings: If you’re feeding a family, making these sandwiches at home can be far more affordable than buying them individually.

Personally, I started recreating the Filet-O-Fish at home when my kids fell in love with it. But let’s be honest—those trips to the drive-thru add up! Once I perfected this recipe, we were hooked, and now it’s a regular part of our dinner rotation.


Ingredients You’ll Need

Before we jump into the recipe, let’s talk ingredients. Here’s what you’ll need to create the perfect homemade Filet-O-Fish:

For the Fish Fillet:

  • 4 cod filets (skinless)
  • 1 teaspoon kosher salt, divided
  • 1 egg
  • 1 tablespoon mayonnaise
  • 1 tablespoon Dijon mustard
  • 1 tablespoon cornstarch
  • 1 tablespoon flour
  • 1/4 teaspoon paprika
  • 2 cups panko breadcrumbs
  • Light oil for frying (vegetable or canola oil works best)

For the Sandwich:

  • 4 soft brioche or potato buns
  • 4 slices American cheese (or half slices for a true McDonald’s replica)

For the Tartar Sauce:

  • 1 cup mayonnaise
  • 2 teaspoons dill relish
  • 1 teaspoon sugar
  • 3 teaspoons white onion, finely chopped

I love using cod for its mild flavor and flaky texture, but you can substitute with haddock or even pollock if that’s what you have on hand.


Step-by-Step Instructions: Creating the Perfect Copycat Filet-O-Fish

Let’s break this down step-by-step so you can create a sandwich that’s crispy on the outside, tender on the inside, and bursting with flavor.

1. Prepare the Wet Batter

In a medium bowl, whisk together:

  • 1 egg
  • 1 tablespoon mayonnaise
  • 1 tablespoon Dijon mustard
  • 1 tablespoon cornstarch
  • 1 tablespoon flour
  • ½ teaspoon kosher salt

This batter is key because it helps the panko breadcrumbs stick and ensures your fish gets that irresistible golden crust.

2. Prep the Panko Breadcrumbs

If you’ve ever wondered why restaurant breading is so crispy, here’s the trick: panko breadcrumbs. For this recipe:

  1. Pulse 2 cups of panko breadcrumbs in a food processor to make them slightly finer. (This mimics McDonald’s light breading.)
  2. Mix the breadcrumbs with ¼ teaspoon paprika and the remaining ½ teaspoon salt.

3. Bread the Fish Filets

Dredge each fish filet in the wet batter, ensuring it’s fully coated, then transfer it to the panko mixture. Gently press the breadcrumbs onto the fish to ensure an even coating.

4. Fry the Fish

  1. Heat about 1 inch of oil in a large skillet over medium-high heat. You want the oil hot enough that it sizzles when you drop a breadcrumb in.
  2. Carefully place the breaded filets into the oil, working in batches to avoid overcrowding. Fry each filet for 3-4 minutes per side, until golden brown and crispy.
  3. Once cooked, transfer the filets to a wire rack or paper towel-lined plate to drain any excess grease.

Pro Tip: Keeping the fish on a wire rack instead of a plate helps maintain its crispiness.

5. Make the Tartar Sauce

While the fish is frying, whip up your tartar sauce. Simply combine:

  • 1 cup mayonnaise
  • 2 teaspoons dill relish
  • 1 teaspoon sugar
  • 3 teaspoons finely chopped white onion

Taste and adjust as needed. I personally like my tartar sauce a little tangier, so sometimes I add a splash of lemon juice or a pinch of garlic powder.

6. Steam the Buns

To get that soft, pillowy bun like McDonald’s, steam your brioche or potato buns for 30-60 seconds. You can do this by placing them in a covered skillet with a small amount of water or using a steamer basket.

Optional: If you prefer a toasted bun, you can lightly toast the insides for extra texture.

7. Assemble Your Filet-O-Fish

Here’s the fun part—putting it all together!

  1. Place a slice (or half slice) of American cheese on the bottom bun.
  2. Top with a hot, crispy fish filet.
  3. Spoon a generous amount of tartar sauce on top.
  4. Cap it with the top bun.

Voila! You’ve got a homemade Filet-O-Fish that’s just as satisfying—if not more so—than the original.


Tips for Perfecting Your Copycat Filet-O-Fish

  1. Use Fresh Fish: The fresher the cod (or your chosen fish), the better the texture and flavor.
  2. Don’t Skip the Panko: Panko breadcrumbs are essential for achieving that light, crispy coating.
  3. Steam Your Buns: This small step makes a huge difference. Soft, steamed buns are part of what makes the Filet-O-Fish so special.
  4. Experiment with the Tartar Sauce: Add a squeeze of lemon, a dash of hot sauce, or even chopped capers for a unique twist.

Serving Suggestions

While the Filet-O-Fish is fantastic on its own, you can round out your meal with a few easy sides:

  • Classic French Fries: Why not go full McDonald’s mode?
  • Coleslaw: A tangy, refreshing side that pairs perfectly with crispy fish.
  • Sweet Potato Fries: For a slightly healthier alternative.

If you’re feeling extra indulgent, whip up a quick milkshake to complete the fast-food experience at home!
