Here it is my friends: the glorious vegetarian fish sandwich with homemade tartar sauce that will satisfy all your Filet-O-Fish cravings and then some. Thanks to Gardein Golden Fishless Filets (not sponsored – I just love them!) this sandwich truly has everything you want in a fish sandwich recipe...without the fish.

As for the vegetarian fish sandwich SAUCE? I've got a homemade tartar sauce recipe that's truly to die for!

I've got to say, this sandwich stands out among all sandwiches – not just vegetarian sandwiches. I really hope you'll give it a try!

"Do vegetarians eat fish?"

If I had a dollar for every time I got this question! Definitely an understandable question because a lot of people say they're vegetarian but they still eat fish.

But...

Technically no, vegetarians do NOT eat fish!

Instead, someone who has a vegetarian diet PLUS fish and other seafood is what's known as pescatarian.

That being said, I also totally understand why a pescatarian would call themselves vegetarian instead because it's easier and quicker to explain.

Now, back to the vegetarian fish sandwich!

Ingredients

Here's what you'll need to make this SUPER easy vegetarian recipe:

Gardein Golden Fishless Filets (2 pieces on each sandwich!)
Really good quality burger buns (I used brioche buns)
Lettuce
Cheese

And no "fish" sandwich is complete without tartar sauce, right?

Homemade tartar sauce recipe

So here's what you'll need for that:

Mayonnaise
Dijon mustard
Sweet green relish
Worchestershire sauce (I use a vegetarian version without fish in it)
Dill
Lemon
Onion powder
Salt and pepper

There are so many tartar sauce recipe variations out there. Some have mustard, some don't. Some with dill, some without. But this is how I like it and I really hope you'll like it too! Not only do I spread it on the sandwich, but dipping your fries - or "chips" for my UK friends - is sooo good too.

Vegetarian fish sandwich toppings

So I'm pretty sure the classic Filet-O-Fish just has tartar sauce and cheese on the bun. But I really like the fresh crunch you get when you add lettuce! Tomato and avocado would be really good too, I think.

Basically go ahead and use any of your favorite fish sandwich toppings and add them to a vegetarian fish sandwich and it'll be good.

Other vegetarian sandwiches

Before we get to the recipe, I wanted to show you a few other vegetarian sandwiches you might be interested in.
