Low FODMAP Homemade Condiments

After Instant Pot recipes and air fryer recipes, my greatest passion for recipe development is clean eating, low FODMAP condiment recipes. Something about writing a recipe for something you would otherwise be forced to buy at a store or consume at restaurant feels liberating somehow, like “sticking it to the Man.” KAPOW! I’m repeatedly shocked at how easy most condiments are to make at home, and after reading the labels of so many condiment bottles and seeing what’s in them, it makes me feel better about what our family is putting in our bodies. Plus, I can make sure the condiments I’m making contain only low FODMAP ingredients.

Tartar Sauce: A Must for Fish and Chips

Fish and chips without tartar sauce is like fries without ketchup. You can enjoy them on their own, but why would you want to? You wouldn’t. That’s why I’ve developed both homemade, low FODMAP ketchup and low fodmap tartar sauce recipes to go with my upcoming low FODMAP Air Fryer Fish and Chips recipe! The fish and chips recipe has been a long time in the making (a looooong time), so I’ve been holding off on posting this tartar sauce until I had it finalized. And guess what? It’s going on the blog next week, so subscribe to be notified by email once that recipe hits the blog! You won’t want to miss it!

Necessary Equipment

Nothing fancy required! The equipment I use to make this low FODMAP, homemade tartar sauce includes:

  • Small bowl
  • Measuring cups and spoons
  • Chopping board and knife
  • Whisk
  • Spoon
a fork dipping a piece of breaded fish into a small bowl of tartar sauce

Low FODMAP Homemade Tartar Sauce: Ingredients & Success Tips

To make this low FODMAP homemade tartar sauce, I whisk together the following ingredients in a small bowl until well combined:

  • Dairy-free mayo – I’m providing the Amazon link for reference, but this one can be found cheaper at Costco.
  • Capers, drained, rinsed and chopped – these can typically be found in the condiment section near the pickles in a glass or plastic jar.
  • Garlic-infused olive oil – I use this in place of regular garlic, which is high in FODMAPs.
  • Lemon juice, freshly-squeezed
  • Fresh dill, chopped
  • Sea salt and pepper

That’s it. Crazy simple. Typically, tartar sauce recipes call for chopped pickles, but as pickles are kind of a wild card in terms of FODMAP content, capers are a much safer bet and add pretty much the same acidity and texture as pickles. According to Monash University’s Low FODMAP Diet App, capers are low in FODMAPs. They typcially come in small jars, but if you hate to buy a whole jar of capers just for one recipe, my low FODMAP Mediterranean Chicken Salad and Instant Pot Chicken Cacciatore recipes also call for capers. Capers are great to have on hand to add a boost of low FODMAP acidity to dishes.

Serving Quantity and Size

I kept the quantities of the ingredients in this tartar sauce recipe quite small as when I make this for two people for one fish and chips recipe, we typically have about half of it leftover. This recipe makes a bit more than 1/4 cup of tartar sauce, which is about two 2-tablespoon servings. If you think you might need more, use the tools in the recipe card below to double or triple the recipe. Slathering this tartar sauce on crab cakes or a fish sandwich may require a higher quantity of tartar sauce than just dipping fish for fish and chips or fish sticks.

Storage

Store in an air tight container in the refrigerator for up to two weeks. My tartar sauce typically lasts even longer though – I always do a visual and “sniff test” before re-serving.
