Tasty Keto Celery Salad

If you ask me, celery is one of the most underrated salad ingredients out there.

This crisp keto-friendly salad brings together three crunchy vegetables with a simple lemon dressing that lets their fresh flavors shine. Thin-shaved fennel and cucumber join forces with celery, all tossed in a bright olive oil and lemon juice mix.

Fresh dill adds an herby note that ties everything together without weighing you down. The mandoline does most of the work here, creating paper-thin slices that make each bite light and refreshing.

It’s a quick side dish that works great alongside grilled meats or fish, perfect for when you want something fresh and satisfying.

What Kind of Celery Should I Use?

For this keto salad, regular green celery from your grocery store works perfectly fine. Look for stalks that are firm and crisp with bright green color – avoid any that look wilted or have brown spots. The inner stalks tend to be more tender and less stringy than the outer ones, so if you’re picky about texture, grab those first. You can use both the stalks and the leaves in this salad, as the leaves add a nice pop of flavor, though most people just stick with the stalks for a cleaner crunch.

Options for Substitutions

This simple salad is easy to customize based on what you have in your kitchen:

• Fennel: If fennel isn’t your thing or you can’t find it, try using thinly sliced radishes or jicama for a similar crisp texture. You could also add more celery to keep that refreshing crunch.
• Cucumber: English cucumbers, Persian cucumbers, or regular cucumbers all work great here. If using regular cucumbers, you might want to peel and seed them first to avoid excess water in your salad.
• Olive oil: Any neutral oil like avocado oil works well, or try walnut oil for a slightly nutty flavor that pairs nicely with the vegetables.
• Lemon juice: Fresh lime juice or white wine vinegar can step in for lemon juice. Start with a bit less vinegar since it’s more acidic, then adjust to taste.
• Salt: Regular table salt, sea salt, or kosher salt all work fine. If using kosher salt, you might need slightly more since it’s less concentrated than table salt.

Watch Out for These Mistakes While Cooking

The biggest mistake when making this keto celery salad is not removing the tough strings from the celery stalks, which can make your salad chewy and unpleasant – use a vegetable peeler to strip them away before slicing. Another common error is cutting your vegetables too thick, so aim for thin, uniform slices that allow the dressing to coat everything evenly and make each bite more enjoyable. Don’t dress the salad too far in advance either, as the salt will draw out water from the cucumber and make your salad watery – if you need to prep ahead, keep the vegetables and dressing separate until about 15 minutes before serving. For extra flavor, let the dressed salad sit for just 5-10 minutes before eating, which gives the vegetables time to absorb the lemon and olive oil without getting soggy.

What to Serve With Celery Salad?

This crisp, refreshing salad pairs beautifully with grilled proteins like chicken thighs, salmon, or steak since the crunchy vegetables and bright lemon dressing cut through richer flavors. I love serving it alongside Mediterranean dishes like lamb chops or Greek-style meatballs, where the fennel and cucumber really complement those herbs and spices. It also works great as a side for a simple rotisserie chicken when you want something light and fresh on the table. Since this salad is keto-friendly, it’s perfect next to cauliflower rice bowls or zucchini noodles topped with your favorite protein and sauce.

Storage Instructions

Store: This salad keeps well in the fridge for about 2-3 days in an airtight container. The veggies will stay pretty crisp, though they might release a bit of liquid as they sit. Just give it a quick toss before serving and you’re good to go.

Make Ahead: You can chop all your vegetables a day ahead and keep them in separate containers, but I’d wait to add the dressing until right before serving. This keeps everything super crisp and fresh tasting. Just toss it all together when you’re ready to eat.

• Calories: 180-220
• Protein: 2-3 g
• Fat: 13-15 g
• Carbohydrates: 14-18 g

Ingredients

For the dressing:

• 3 tbsp olive oil (I prefer Lucini Premium Select for a peppery finish)
• 1.5 tbsp lemon juice
• 3/4 tsp salt

For the salad:

• 1.25 cup fennel (shaved paper-thin with a mandoline)
• 1.25 cup celery
• 1.25 cup cucumber (peeled and sliced into 1/4-inch moons)
• 2 tbsp fresh dill, chopped

Step 1: Prepare the Vegetables

• 1.25 cup fennel
• 1.25 cup celery
• 1.25 cup cucumber

Using a mandoline, shave the fennel bulb paper-thin to maximize surface area for the dressing.

Chop the fennel fronds separately and set aside.

Cut the celery stalks into 1/4-inch slices on a slight bias—this creates more visual interest and helps them absorb the vinaigrette.

Peel the cucumber and slice it into 1/4-inch moons.

I find that peeling cucumber prevents any bitterness from the skin and gives the salad a more refined appearance.

Keep all vegetables separate until ready to dress, as this prevents them from releasing excess liquid too early.

Step 2: Make the Vinaigrette

• 1.5 tbsp lemon juice
• 3/4 tsp salt
• 3 tbsp olive oil

In a small bowl, whisk together the lemon juice and salt first, allowing the salt to dissolve slightly into the acid.

Then slowly whisk in the olive oil to create an emulsion—the high-quality peppery olive oil you use here really matters, as it’s the star of the dressing in such a simple recipe.

The emulsification helps the dressing coat the vegetables evenly rather than pooling at the bottom of the bowl.

Step 3: Combine and Finish

• prepared vegetables from Step 1
• 2 tbsp fresh dill, chopped
• vinaigrette from Step 2

Add all the prepared vegetables from Step 1—including the fennel fronds—and the fresh dill to the vinaigrette.

Toss gently but thoroughly to coat everything evenly.

I like to let the salad sit for just 2-3 minutes before serving so the vegetables can absorb some of the dressing while still maintaining their crisp texture.

Serve immediately for the best crunch and freshness.
