This is a five-ingredient tartar sauce you can mix in the time it takes to plate everything else. It uses mayonnaise, dill relish, fresh dill, garlic powder, and onion powder — all naturally gluten-free, so no label-checking required. If you need a reliable condiment for a fish burger or fried chicken sandwich and you need it fast, this is it.
Why this recipe works
Two things carry this sauce. First, dill relish does double duty — it adds the briny, sweet-sour note that defines tartar sauce while also providing enough moisture to loosen the mayo into a spreadable consistency without watering it down. Second, using both fresh dill and onion powder gives you two distinct layers of flavor: the fresh herb adds brightness right at the end, while the onion powder works into the base and rounds out the savory backbone. Neither alone does what both together do.
Common problems and fixes
- Sauce tastes flat: Mayonnaise brands vary a lot in salt and acidity. Taste before serving and add a small squeeze of lemon juice or a pinch of salt to sharpen the flavor.
- Watery texture after refrigerating: Fresh dill releases moisture as it sits. If the sauce looks thin after chilling, stir it well — it usually comes back together. If not, whisk in a teaspoon of additional mayo.
- Garlic powder clumps: Measure garlic and onion powder into the mayo first and whisk them in before adding the relish and dill. Dry spices disperse more evenly in fat than in a wet mixture.
- Sauce is too sweet: Some dill relish brands skew sweet. If yours does, swap half the relish for finely chopped dill pickles to bring the brine back into balance.
- Fresh dill is too strong: Fresh dill intensity varies by bunch. Start with slightly less than the recipe calls for, taste, and add more. You can always add; you can’t take it out.
Smart swaps
- Fresh dill: If you only have dried dill, use one teaspoon in place of the fresh. Dried is more concentrated, so go light and taste as you go.
- Mayonnaise: Any full-fat mayo works. Avocado-oil mayo keeps it gluten-free and dairy-free. Low-fat mayo tends to make the sauce thin and a little sweet — skip it if you can.
- Dill relish: Sweet relish is not a straight swap here; it will make the sauce noticeably sweeter and less tangy. Finely minced dill pickles are a better substitute if dill relish isn’t available.
Storage and reheating
Store the sauce in a sealed container in the fridge for up to five days. The flavor actually improves after a few hours as the spices settle in, so making it the night before is a smart move. Do not freeze it — mayonnaise breaks when frozen and thawed, leaving you with a greasy, separated mess. There is no reheating step; serve it cold straight from the fridge.

Frequently asked questions
Is store-bought mayonnaise always gluten-free?
Most major US mayonnaise brands are gluten-free, but always check the label since formulations can change. Look for a certified gluten-free mark if you are cooking for someone with celiac disease rather than a general gluten preference.
Can I make this sauce ahead of time?
Yes, and it’s actually better if you do. Letting it sit in the fridge for at least an hour gives the garlic powder and onion powder time to bloom into the mayo. Make it the night before and it will taste noticeably more cohesive.
What burgers or sandwiches pair well with this tartar sauce?
It works best alongside fish burgers and crispy fried chicken sandwiches where the tang cuts through the richness of the fried coating. It also works as a spread on a veggie burger in place of plain mayo.
How do I know if my dill relish is gluten-free?
Pure dill relish is made from cucumbers, vinegar, and spices — all gluten-free ingredients. Check the label for any added thickeners or malt vinegar, which contains gluten, especially on store-brand products.
Can I use this as a dipping sauce, not just a spread?
Yes. The consistency straight from the recipe is thick enough to spread but thin enough to dip. If you want it slightly looser for dipping, whisk in half a teaspoon of lemon juice or pickle brine.
The recipe makes six servings — how much is one serving?
The recipe uses three-quarters of a cup of mayo plus the other ingredients, which comes out to roughly two tablespoons per serving for six people. That is a generous spread for one burger or a small dipping portion.
