We try to not eat a lot of fast food.  Face it though … sometimes you get a craving.  When Lent rolls around, we always have to get at least one McDonald’s Filet ‘0 Fish Sandwich! It’s my hubby and youngest daughter’s FAVORITE thing on the menu.

 

Let’s face it … a lot of what’s to love is the SAUCE!  Nothing beats a good tartar sauce.

A while back my mom told me she had been using a copy cat recipe for McDonald’s tartar sauce for years.

Excuse me, Mother??  How am I just hearing about this NOW?!

I promptly had her text it to me, and I set out to mimic their whole sandwich.

What Makes up a McDonald’s Filet ‘O Fish Sandwich?

So, you know that for me, it’s the tartar sauce all the way!  We have the recipe for that, but what about the rest?

If you ask my daughter what she likes most, she will tell you the bun.  So, I did some research to find out how it’s always so soft.  I read that they steam them.  Brilliant!  

I steam tortillas all of the time, that would be easy.  So, I had the bun, I had the sauce, the cheese is basic American slices.  Now the fish.  

Many people claimed to use Mrs. Paul’s fish fillets.  No offense to them, but I was raised on Van de Kamp’s.  Growing up Catholic, we ate it plenty over the years.  

I decided to take a look and see what they had that would be a good fit for the bun.  They had one that was square in shape, they even call them “Breaded Fish for Sandwiches.”

Steam Your Buns

Steaming the bun was easy.  I simply placed them in a plastic bag, with a damp paper towel laid over the top, and microwaved them for about 30 seconds.  Perfectly steamed.

Mayo, dried onion, dill pickle relish, capers, lemon juice, parsley, milk and a little bit of sugar. That’s the secret.

 

What Is Tartar Sauce?

Tartar sauce is a mayo-based sauce that primarily gets its flavor from chopped up capers, lemons, and chopped gherkins. The name comes from the fact that the taste is tart. 

My Mother’s borrowed tartar sauce recipe really tastes like the McDonald’s tartar sauce, and it doesn’t use the sweet gherkins.  It actually calls for dill pickle relish.

To this day, when someone says “tartar sauce” I pretty much always think of that style tartar on a filet of fish sandwich. 

The power of marketing should never be underestimated!

What are capers anyway?

We all know a pickle is a pickle still even if you call it a gherkin. However, some people might not be familiar with capers, and this tartar sauce recipe calls for minced capers.

Capers are the flower buds of the Finders Rosebush. (Some call it a caper bush but I think Finders Rose has a lot more elegance to it… and capers are served with lots of elegant foods, like lox for example).

A caper berry, more specifically a Finders Rosebud, is salted and pickled to create a wonderful little tangy treat. 

The small ones sort of resemble green peppercorns. However, there are also larger ones that look more like an olive. You can use either because they both have a similar taste.

Cheese On Filet Of Fish?

Ordinarily, fish and cheese are not really a match made in food heaven. Somehow, putting cheese on a filet o fish sandwich beats the odds and wins the tasty lottery. 

I know, I know, anytime I post a recipe and use American cheese slices, I catch heck for it.   

It might not be the best cheese ever, and you might avoid it any other day of the week, but let a guilty pleasure be just that. Enjoy the fact that you are making your own filet of fish sandwich at home, and not using the car to go get one.

Lowering the carbon footprint is a good thing.

 

Wondering What “American Cheese” Actually Is?

You might be wondering what American cheese actually means. In reality, it is just a generic label for a style of cheese. Just like “Swiss” cheese refers to a variety of cheeses that have a specific name and style of processing. 

In most cases, American cheese refers to a mild cheddar or Colby style cheese. So if you want to avoid using individually wrapped slices of processed American cheese then those are the ones to look out for, but it won’t truly be a copy cat of the McDonald’s Filet ‘o Fish Sandwich.

So, the fish was baked, topped with the cheese when it was piping hot, slathered with some tartar sauce and the steamed bun was placed on top.  Of course, french fries were in order.

Dinner was made.

  1. Great idea!! It was simple to make and tasted just like the real thing, maybe a little healthier though? πŸ˜‰

  2. This looks SOOO good – and with McDonalds currently closed in the UK due to the current situation, I may just have to make these for the whole family.

  3. My husband thinks I’m crazy but the filet o fish is actually my favorite mcdonalds sandwich! How fun that I can now make it at home- can’t wait to try it!

  4. I feel so dumb for asking this but does the damp paper towel go directly on the bun inside the bag and should the bag be closed or left open? Thanks!

  5. I know cheese is good (can’t get enuf o’ that gooey stuff) but if you’re replicating the FoF sandwich, there’s only half a slice of cheese on it. Been making them at home for quite a while (Gorton’s Fish Sandwich fish). Now I have the “right” copycat sauce. Was just wingin’ it. Always used sweet relish. Gonna try this recipe with dill tonite! (It’s Friday!)

  6. The tartar sauce is spot-on! Loved it. Will be my go-to from now on. I used the Gortons breaded fish filets and made them in the air fryer. They tasted exactly like Mcdonalds. maybe even better!

  7. I love fish sandwiches, not a fan of cheese it though. I like the tarter sauce recipe. Where do you find the larger fish patties? The ones I have found are smaller.

    1. I know what you mean, and it seems they continue to GET smaller all of the time. (and cost more! lol!!) I just used the ones that I could find in my area that were square when I made these. Of course, you could substitute breaded filets or even fish sticks and load up the bun how you like! I think that the tartar sauce and the bun are what really make this sandwich!

  8. I’ve loved McDonald’s tartar sauce since I was a kid and I’m ALWAYS disappointed in the store bought tartar sauces. I’m never buying them again, because THIS tartar sauce recipe is easy to make and tastes just like McDonald’s! Thank you!
