intro

Creamy, tangy, briny homemade tartar sauce, the perfect cool accompaniment for fried seafood, crab cakes, and fish and chips, made with simple pantry staples.

Ingredients

Full-fat mayonnaise 1 cup (240g)
Dill pickles 1/3 cup (50g)
Capers (rinsed) 2 tablespoons (20g)
White onion 2 tablespoons (20g)
Fresh dill 2 tablespoons (6g)
Dijon mustard 1 teaspoon (5g)
Fresh lemon juice 1 tablespoon (15ml)
Kosher salt 1/4 teaspoon (1g)
Freshly ground black pepper 1/8 teaspoon (0.5g)
Dill pickle brine (optional) 1 teaspoon (5ml)

Steps

1

Prep chopped mix-ins

First, pat 50g (1/3 cup) dill pickles dry with paper towels to remove excess brine, then finely dice them into uniform 2mm pieces. Rinse 20g (2 tablespoons) capers under cold running water, pat dry, and finely chop; mince 20g (2 tablespoons) white onion into fine, even pieces, and chop 6g (2 tablespoons) fresh dill fronds, discarding any thick, woody stems.

Step 1
step1:Prep chopped mix-ins
2

Mix creamy base

Add 240g (1 cup) full-fat mayonnaise to a medium glass mixing bowl, then stir in 5g (1 teaspoon) Dijon mustard and 15ml (1 tablespoon) freshly squeezed lemon juice. Mix with a silicone spatula at room temperature until completely smooth with no lumps, about 30 seconds of steady, gentle stirring.

Step 2
step2:Mix creamy base
3

Fold in solid ingredients

Add the prepped diced pickles, chopped capers, minced white onion, and chopped fresh dill to the mayonnaise base. Fold gently with the spatula to evenly distribute the solid ingredients throughout the creamy base, taking care not to over-mix (which can break the mayo and cause watery texture), about 20 seconds of slow folding.

4

Season and adjust flavor

Add 1g (1/4 teaspoon) kosher salt and 0.5g (1/8 teaspoon) freshly ground black pepper to the sauce, then stir to combine. Taste the sauce, and if you prefer extra tang, stir in 5ml (1 teaspoon) reserved dill pickle brine, adding 1ml increments at a time to avoid thinning the sauce too much.

step4:Season and adjust flavor
5

Chill to meld flavors

Transfer the mixed tartar sauce to an airtight glass jar, seal the lid tightly, and place it in the refrigerator set to 4°C (40°F) for a minimum of 30 minutes to allow the flavors to meld together before serving.

6

Stir and serve

After chilling, remove the jar from the refrigerator, give the sauce a quick 10-second stir to reincorporate any small amount of separated liquid, and serve alongside fried fish, crab cakes, fish and chips, or fried shrimp. Store leftover sauce sealed in the fridge for up to 1 week.

Tips

1.Always pat diced pickles and rinsed capers dry with paper towels before adding them to the sauce; excess brine will thin the mayonnaise base and result in a watery, less creamy texture.
2.Use full-fat mayonnaise for the richest, most stable texture; low-fat or light mayonnaise has added water and fillers that cause the sauce to separate easily and taste overly tart.
3.Do not skip the 30-minute chill time: this resting period allows the briny, herby, tangy flavors to meld together, rather than tasting like plain mayonnaise with scattered mix-ins.

Tartar Sauce:Frequently Asked Questions

1.How long will this homemade tartar sauce stay fresh in the refrigerator?
Stored in a tightly sealed, airtight glass jar, this tartar sauce will keep well for 10 to 14 days in the coldest part of your fridge (usually the back of a lower shelf, not the door). Give it a quick stir before each use, and discard it immediately if you notice any off smell, mold, or separated texture that doesn’t blend back together with stirring.
2.Can I use low-fat or light mayonnaise instead of full-fat mayonnaise for this recipe?
You technically can, but I don’t recommend it for the best classic texture and flavor. Light mayo often has added stabilizers, extra water, and a thinner, slightly artificial aftertaste that throws off the rich, creamy, tangy balance. If you do use it, drain your pickles, capers, and onion extra well to avoid a watery, runny final sauce.
3.My tartar sauce turned out watery—how do I fix it, and how can I prevent this next time?
Watery tartar sauce almost always comes from excess brine or moisture clinging to your mix-ins. To fix a thin batch, stir in an extra 1 to 2 tablespoons of full-fat mayo, or chill it for 30 minutes to let the ingredients firm up. Next time, pat your rinsed capers, chopped dill pickles, and diced white onion dry with a paper towel before mixing to cut down on extra liquid.
4.I don’t have fresh dill on hand—can I use dried dill as a substitute?
Yes, dried dill works as a fine substitute in a pinch, though you’ll get a brighter, fresher flavor from fresh. Use 1 teaspoon of dried dill for every 1 tablespoon of chopped fresh dill called for, since dried herbs are far more concentrated. Let the sauce rest for 20 minutes after mixing to let the dried dill rehydrate and its flavor meld.
5.What are the best ways to serve this classic tartar sauce, besides fried fish?
This tangy, briny sauce is way more versatile than just a fish fry staple! It pairs beautifully with crispy fried shrimp, clam strips, baked salmon, crab cakes, and classic fish and chips, of course. It also works great as a dip for fried pickles, roasted potato wedges, crispy chicken tenders, or a zesty spread for cold fish sandwiches and lobster rolls.
6.Do I really need to rinse the capers before adding them to the sauce?
Rinsing capers is a small step that makes a huge difference in final flavor. Capers are packed in very salty, briny vinegar, and skipping the rinse will leave your tartar sauce overly salty and sharp, with a one-note briny bite. A quick 10-second rinse under cool water, followed by a light pat dry, washes off excess surface brine for balanced flavor.
7.Can I make this tartar sauce ahead of time for a party or fish fry?
Absolutely—this sauce actually tastes better when made ahead! Mix it up 12 to 24 hours before you plan to serve it, store it in an airtight container in the fridge, and the flavors will meld into a smoother, more cohesive, well-balanced sauce. Give it a quick stir right before serving to recombine any slight separation.

OMG this tartar sauce is a total game changer! I used to just grab the jarred stuff from the grocery store for our weekly fish fry nights, and I never realized how much better homemade tastes. My kids even asked for extra to dip their tater tots in, that’s how good it is! Only took 10 minutes to throw together, and the chill time let all the dill and pickle flavors meld perfectly. Will be making this for every potluck from now on!

Wait I dipped my tater tots in it too! Thought I was the only weirdo who did that, so glad I’m not alone. It’s so creamy, way better than the sad ranch we usually have with tots.

So happy to hear it was a hit with your family! It’s such a versatile dip—we love it with everything from fried fish to roasted veggies too, no judgment on the tot dipping at all. If you want a little extra zing next time, try tossing in a pinch of Old Bay!

Really solid tartar sauce recipe! I made this to go with the coconut shrimp I made for my family dinner last Sunday, and everyone raved. I knocked a star off because I felt like it needed just a little more lemon juice for my taste, but that’s just personal preference. Super easy to make, even for someone who burns toast half the time like me.

Thanks so much for the honest feedback! You’re totally right, lemon juice is totally adjustable to taste—we love that you can tweak this base recipe to match exactly what you love. Adding an extra squeeze is the perfect move if you love that bright, tangy kick!

SO good, I prepped a big batch of this on Sunday to use for my work lunches all week. I’ve been slathering it on salmon burgers, dipping fried zucchini in it, even adding a dollop to my Cobb salad for extra tang. It held up perfectly in the fridge all week, no weird separation or watery texture like some homemade sauces get. 10/10, this is going to be a permanent meal prep staple for me now.

I brought this to our neighborhood block party potluck last weekend to go with the fried fish platter, and people would NOT stop asking me for the recipe! A couple people even said it was better than the tartar sauce at our favorite local seafood shack. I added a tiny bit of extra sweet relish because that’s how my grandma used to make it, and it turned out chef’s kiss.

3 days ago

Wait I was at that party! I must have put three spoonfuls of that on my fish, no lie. I came on here looking for the recipe after I saw you post about it in the neighborhood Facebook group, can’t wait to make it myself this weekend for our fish fry.

Quick question before I make this this weekend—can I use dill pickle relish instead of chopped dill pickles? I have a half jar of relish in the fridge I need to use up, and I don’t feel like making a special grocery run. Also, does this work with dairy-free mayo? My son has a dairy and soy allergy so I have to swap a lot of ingredients for our family dinners.

just now

I made this last week with dairy-free avocado oil mayo and dill relish, and it turned out amazing! No one could tell it wasn’t made with regular mayo, it was just as creamy. I didn’t notice a texture difference from using relish instead of hand-chopped pickles at all.

just now

Great question! Dill relish works perfectly as a swap for diced pickles here—just give it a quick taste first; if it’s extra sweet, you can cut back a tiny bit on the added sugar in the recipe if you prefer a more tangy sauce. Dairy-free mayo works great too, just give it an extra good stir before popping it in the fridge to chill for the full 30 minutes to make sure everything combines smoothly. Hope your son loves it!
