Keto Cucumber & Dill Salad

Let me paint you a picture. It’s 4:00 PM in July. My kitchen faces west, which means it’s basically a pizza oven. The last thing I want to do is turn on the stove. My family is circling the kitchen like hungry sharks, asking, “What’s for dinner?” and I have zero energy for anything complicated.

I was about to just hand everyone a block of cheese and call it a day. But then I remembered the bag of cucumbers sitting in the crisper drawer—the ones that were about two days away from turning into sad, wilted science experiments.

I grabbed two of them, a cutting board, and started rummaging through the fridge. A half-used jar of sour cream. A bunch of dill that was surprisingly still perky. A lemon. And just like that, this Keto Cucumber & Dill Salad was born.

The first time I made it, I wasn’t even on keto. I was just lazy and hot. But after taking a bite—that cold, creamy, tangy, herby crunch—I literally said out loud to my empty kitchen, “Where have you been all my life?”

Now, three years later? I make this salad at least twice a week. It’s saved more sad grilled chicken dinners than I can count. It’s the thing I bring to summer BBQs where I know the host forgot about the low-carb people. And honestly? It’s just good. Not “good for a keto recipe” good. Actually, genuinely, I-want-to-eat-this-with-a-spoon-good.

So let me show you how to make it. No fancy techniques. No obscure ingredients. Just a bowl of cold, creamy perfection that takes five minutes.

Ingredients (Grab These, You’re Almost Done)

I’m writing this exactly how I make it in my own kitchen. No weird measurements like “a pinch of celestial salt.” Just real amounts.

For the Salad:

2 medium English (hothouse) cucumbers – These have fewer seeds and thinner skin. Regular garden cukes work too, just scoop out the seeds.
¼ cup fresh dill, finely chopped – Please don’t use dried. I tried it once. It was sad. The fresh stuff is non-negotiable here.
¼ cup red onion, very thinly sliced – A mandoline is your friend here. Or just cry like I do.

For the Creamy Dill Dressing:

½ cup full-fat sour cream – Do not use low-fat. It’ll be watery and sad. Full fat is where the magic (and keto fat macros) live.
2 tablespoons mayonnaise – Duke’s or Hellmann’s. I’m not starting a mayo war, but full-fat, please.
1 tablespoon fresh lemon juice – Bottled works in a pinch, but fresh is brighter.
1 clove garlic, minced (or ½ teaspoon garlic powder) – I use fresh because I’m a masochist who likes garlic hands.
½ teaspoon salt – More to taste at the end.
¼ teaspoon black pepper – Fresh cracked is best.
1 teaspoon white vinegar or apple cider vinegar – This is my secret weapon for brightness.

Optional Garnish:

Extra dill sprigs
Sprinkle of smoked paprika or everything bagel seasoning

Step-by-Step Instructions (I Promise, It’s Easy)

Step 1: Prep the cucumbers (don’t skip the salt step).
Wash your cucumbers. If you’re using English cucumbers, just slice them into thin coins—about ⅛-inch thick. If you’re using regular garden cucumbers, peel them first (the wax can be weird), then slice. Here’s a tip I learned the hard way: put the sliced cucumbers in a colander, sprinkle with ¼ teaspoon of salt, and let them sit for 5 minutes. This draws out excess water so your dressing doesn’t get watery. I forgot this once and ended up with cucumber soup. Learn from my mistake.

Step 2: Slice the onion and dill.
While the cucumbers are sweating in the colander, thinly slice your red onion. You want them almost see-through. Too thick and they’ll overpower everything. Then take your fresh dill and run your knife through it until it looks like green confetti. Don’t overthink the chopping—just get it fine.

Step 3: Make the dressing (this takes 30 seconds).
In a medium mixing bowl, add your sour cream, mayonnaise, lemon juice, minced garlic, salt, pepper, and white vinegar. Whisk it together with a fork or a small whisk. It should look thick, creamy, and pale greenish-white. Taste it here. Does it need more salt? More lemon? Adjust now before the cucumbers go in.

Step 4: Squeeze the cucumbers.
Here’s the gross but important part. Take your salted cucumber slices and press them between paper towels or a clean kitchen towel. Squeeze gently. You’ll be shocked how much water comes out. Pat them dry. This is the difference between a creamy salad and a watery one.

Step 5: Toss it all together.
Put the dry cucumbers, sliced red onion, and chopped dill into the bowl with the dressing. Use a rubber spatula or big spoon to gently fold everything together until every cucumber coin is coated in that creamy, herby goodness. Don’t stir like a maniac—you’ll break the cucumbers.

Step 6: Taste and adjust (the chef’s privilege).
Grab a cucumber slice. Eat it. Does it need more salt? A crack of pepper? Another tiny squeeze of lemon? Now’s the time. Keto food can feel heavy sometimes, so I usually add an extra tiny splash of vinegar here to wake it all up.

Step 7: Chill or serve immediately.
You can eat this right away. It’s delicious. But if you have 20 minutes, pop it in the fridge. Cold is better. Next-day cold is the best. The dill and onion mellow out and the whole thing becomes one harmonious bite.

Pro Tips & Tricks (From My Kitchen to Yours)

Don’t skip the salting + squeezing step. I know it feels like an extra chore. But cucumbers are basically water balloons. If you don’t draw that water out, your beautiful creamy dressing will be a puddle by the time you sit down to eat. I learned this after serving “Cucumber Soup Salad” to my mother-in-law. Never again.

Use a spoon to scrape the cucumber seeds (if needed). If you’re using garden cucumbers with big, watery seeds, slice the cucumber in half lengthwise and run a teaspoon down the center to scoop them out. English cucumbers don’t need this.

Let it rest for 20 minutes before serving if you can. The flavors genuinely get better. The dill infuses into the sour cream, and the red onion loses its sharp bite. It’s like magic but with less wands.

Store leftovers in a glass container. Plastic seems to trap moisture and make the salad weep faster. Glass container with a tight lid? This thing lasts 3 days easily. Maybe 4 if you’re brave.

Variations & Substitutions (Make It Yours)

Dairy-Free Version: Swap the sour cream for full-fat coconut yogurt or a cashew-based sour cream (Kite Hill makes a good one). Use vegan mayo. Honestly? It’s still delicious. Just a little more tropical tasting.

Spicy Keto Cucumber Salad: Add ½ teaspoon of crushed red pepper flakes or a drizzle of sriracha (check your carbs—some have sugar). I also love throwing in a minced serrano pepper. The cool cucumber + spicy kick is addictive.

Greek-Style Twist: Swap the dill for fresh oregano and mint, add ¼ cup crumbled feta cheese, and use Greek yogurt instead of sour cream. You’ll feel like you’re on a rooftop in Santorini. I made this for a potluck and three people asked for the recipe.

Extra Crunch Version: Throw in a handful of crushed pork rinds or some toasted hemp hearts right before serving. Gives it that “crouton” crunch without the carbs.

Serving Suggestions (What to Eat With This)

This Keto Cucumber & Dill Salad is a team player. It’s not the main character—it’s the best friend every main dish needs.

Next to grilled meats. Seriously, serve this next to a juicy bunless burger or grilled chicken thighs. The cold creaminess against hot, smoky meat? Perfection.
As a topping for smoked salmon. Pile it on top of smoked salmon over a bed of greens. Fancy brunch at home without the $18 price tag.
Inside a low-carb wrap. Stuff it into a Mission low-carb tortilla with some rotisserie chicken and bacon. Best lunch ever.
With keto “crackers.” Those Whisps cheese crisps or almond flour crackers? Use them to scoop this salad like a dip. Dangerous. In a good way.
At a summer BBQ. Bring this instead of potato salad. No one will miss the potatoes. I promise.

FAQ’s

How long does this Keto Cucumber & Dill Salad last in the fridge?
Properly stored in an airtight glass container, it’ll last 3 days. After that, the cucumbers start to get soft and release water. It’s still safe to eat, just less crispy. Pro tip: if it gets watery, drain off the liquid and stir in a fresh spoonful of sour cream to revive it.

Can I freeze this salad?
Please don’t. Cucumbers are mostly water. Freezing turns them into mushy, translucent little disasters when thawed. This salad is meant to be fresh. Just make a smaller batch if you’re worried about leftovers.

Can I use dried dill instead of fresh?
You can, but I’ll be sad for you. Dried dill has a dusty, almost hay-like flavor compared to the bright, feathery punch of fresh dill. If you’re in a pinch, use 1 tablespoon of dried dill, and let the salad sit for an hour before eating so it rehydrates a bit.

Is this salad actually keto-friendly?
Yes. Using full-fat sour cream and mayo keeps the fat high and carbs low. One serving (about ¾ cup) has roughly 3g net carbs, 12g fat, and 3g protein. Just watch your portion size—it’s easy to eat half the bowl in one sitting (ask me how I know).

Why did my salad get watery after an hour?
You probably skipped the salting and squeezing step, or your cucumbers were extra watery (looking at you, farmers market heirlooms). Next time, salt the slices and let them sit for 10 minutes, then really press them dry between towels. You can also serve the salad over a paper towel-lined bowl to absorb excess liquid as it sits.

Can I make this a day ahead for a party?
Absolutely yes. This is my go-to make-ahead salad. Make it the night before, store it in the fridge, and give it a good stir before serving. The flavors will be even better. Just know the cucumbers will be slightly less crunchy—still delicious, just softer.

Final Thoughts

Look, I’m not a chef. I’m not a nutritionist. I’m just a home cook who got really tired of eating sad lettuce and grilled chicken every single day on keto. This salad came out of desperation on a hot summer afternoon, and now I can’t imagine my kitchen without it.

It’s forgiving. It’s fast. It’s the kind of recipe you’ll memorize after making it twice and then just eyeball forever (which is what I do now).

So here’s my challenge to you: make this tonight. Even if you’re not keto. Even if you think you don’t like cucumbers. Even if you’re tired and it’s 7 PM and the last thing you want to do is chop anything. Just make it. And when you take that first cold, creamy, dill-infused bite? You’re going to text me (metaphorically) and say, “Okay, I get it now.”

Let me know how it turns out for you. Did you add something awesome I haven’t tried? Did your kids actually eat it? (Mine do, shockingly). Drop a comment or tag me in your photo. I genuinely love seeing these salads come to life in other people’s kitchens.
