Tartar Sauce. It’s a classic accompaniment to fish. It’s great on a fish sandwich or with a piece of fried halibut or cod or baked salmon.
That being said, it isn’t a great accompaniment to the waistline. My favorite brand, Marina Tartar sauce, packs a walloping 180 calories and 20 grams of fat in two tablespoons. Two tablespoons? Let’s face it. Who really sticks to serving sizes? So, I bet it’s safe to say the calorie count on a tartar sauce accompaniment to a fish sandwich can run far higher than 180.
Tackling this juggernaut has been on my recipe bucket list for some time but it was only recently that I nailed a real solution. I bought an Instant Pot back in August and have been making some really gorgeous yogurt in it every week. (I use the recipe from This Old Gal.) I generally have two quarts of homemade yogurt on hand each week and as a result, I have been finding all sorts of amazing ways to add this creamy protein-packed ingredient into my everyday meals.
That’s where my low-fat tartar sauce comes in. On Saturday, I had a piece of defrosted Alaska halibut in the fridge and some white hamburger buns on the counter. Both needed to be used up and I was in recipe development mode. So, I decided to make a halibut sandwich and that’s when the idea for yogurt tartar sauce was born
Admittedly, I was a bit doubtful. I tossed the idea out to my husband. He was really doubtful. Nonetheless, I went at it, substituting my yogurt for the mayonnaise and adding Western Family dill relish, some diced Walla Walla onion, the juice of half a lemon and some salt. A quick stir resulted in a luscious tartar with all the flavor of the classic and far less fat. Dolloped on a piece of cooked panko coated halibut it was a revelation.
The recipe that follows is ridiculously simple. If you don’t have homemade yogurt, storebought is fine. If you use Greek yogurt, you might need to thin it with a bit of milk to get that dollopy texture. Thin it a bit in the beginning, then add your relish, onion, and lemon juice, and if the texture needs adjusting, add a bit more milk or lemon if desired
1/2 cup homemade plain yogurt, or store-bought plain Greek yogurt
2 to 3 teaspoons prepared dill relish, I used Western Family
1 to 2 Tablespoons chopped sweet onion
juice of half a lemon
salt to taste
In a small bowl, whisk or stir the yogurt to loosen and smooth out. Add the relish, the chopped onion, the lemon and salt to taste. Stir to combine and if using Greek yogurt, add a little milk or more lemon juice to adjust the texture. Make 1/2 cup.
