This lemon arugula salad is what happens when a salad stops being a side and starts being the whole point. Peppery arugula, shaved fennel, chewy barley, and toasty walnuts come together in 20 minutes — then the lemon tarragon dressing melds it all into something you’ll crave at addictive levels. It tastes like a fancy restaurant salad, but I can get every ingredient from a Oklahoma grocery store— and that’s saying a lot!
Once you’re on team fun-salad, keep it going. My avocado caprese salad is creamy and summery, my strawberry mixed greens salad bring the sweet-meets-peppery magic, and my sweet & crunchy chickpea salad is the make-ahead lunch that holds up all week.
Arugula Salad Recipe Highlights
I first made this one on a Sunday after a farmers market run, mostly because I’d bought a fennel bulb with big intentions and no plan. It’s been on repeat ever since, and it’s a fresh salad to bring to a summer cookout. My teenagers even eat it — mostly for the “addictive” dressing, but I’ll take the win. Here’s why it earns a spot in your lunch rotation:
- It’s actually filling — no meat required. This is 100% plant-powered, and it still eats like a meal. Barley brings hearty, chewy texture and fiber, walnuts add crunch and healthy fats, and honey (or maple syrup) rounds it out with a touch of natural sweetness. Plants, grains, and good fats covering your macros without you having to think about it — that’s how I’ve fed my family for over a decade.
- Every bite is a little different. Crisp fennel with its subtle licorice whisper, sweet snap peas, peppery arugula, nutty barley — the textures and flavors keep your fork going back in. This is the “fun salad” your lunch routine has been missing.
- The dressing is the glue. Bright lemon, fresh tarragon, a whisper of Dijon, and a touch of honey shake together into a dressing that pulls every ingredient into one addictive bite. Fair warning: you’ll want to put it on everything this week. I’ve been known to dip snap peas straight into the jar.
- 20 minutes, start to finish. Cook the barley, shave the fennel, shake the jar, toss. That’s dinner-party impressive on a Tuesday-lunch timeline — with time left over to actually sit down and eat it.

Recipe Tips
- Make it your own. Swap barley for cooked quinoa, use maple syrup instead of honey to make it vegan, or trade snap peas for cucumber if that’s what’s in the crisper.
- Shave the fennel thin. The thinner the fennel, the more delicate and sweet it tastes — thick slices read as licorice-forward, paper-thin slices read as crisp and fresh. A sharp knife works; a mandoline makes it effortless.
- Cook the barley ahead. Batch-cook it on Sunday and refrigerate. Then this salad becomes a 5-minute assembly job all week.
- Toast the walnuts. Two minutes in a dry skillet deepens their flavor and makes the crunch even better. Watch them closely — they turn fast.
- Dress it right before serving. Arugula wilts quickly once dressed. If you’re meal-prepping, keep the dressing in its jar and drizzle at lunchtime.
Hearty Lemon Arugula Salad with Barley
Jen HansardIngredients
- ¼ cup barley uncooked
- ½ fennel bulb thinly sliced
- 4 cups arugula
- ½ cup sugar snap peas
- ¼ cup raw walnuts chopped
- 2 tablespoons green onion thinly sliced
Lemon Tarragon Dressing
- 2 tablespoons lemon juiced
- 1 teaspoon raw honey
- ¼ cup extra-virgin olive oil
- 2 tablespoons tarragon fresh
- ½ teaspoon Dijon mustard
- dash sea salt, unrefined
- dash black pepper, ground
- 1 tablespoon chives chopped
Instructions
- Cook the barley according to the package directions and let cool.
- Cut the green stalks off the fennel. Halve the bulb and carefully remove the core. Place the halves cut side down and use a very sharp knife to thinly slice or shave the fennel.
- Combine the fennel, arugula, barley, snap peas, walnuts and green onion in a bowl.
- Make the dressing: Place the lemon juice, honey, olive oil, tarragon, mustard, salt, pepper and chives in a small jar and shake well. Refrigerate until ready to use.
- Drizzle the dressing over the salad, gently toss and serve immediately.
Recipe Notes
- Make Ahead: Cook the barley up to 3 days ahead and refrigerate until you’re ready to assemble the salad.
- Gluten-Free: Barley contains gluten, so use cooked quinoa in its place for a gluten-free salad.
- Vegan Swap: Use maple syrup instead of honey to make the dressing vegan.
- Storing: The dressing keeps in a jar in the fridge for up to 1 week. Shake well before using.
Nutrition
Yes, with one rule: keep the dressing separate. The barley can be cooked up to 4 days ahead, the vegetables can be prepped the night before, and the dressing keeps in the fridge for up to a week. Toss everything together right before eating so the arugula stays perky.
Milder than you’d think! Raw, thinly shaved fennel is crisp like celery with a light, sweet licorice note — it brightens the salad rather than dominating it. If you’re fennel-hesitant, this is the recipe to win you over.
For a light lunch, yes — the barley, walnuts, and olive oil give it real staying power. Want to stretch it into a heartier dinner? Toss in white beans or chickpeas (they love this dressing), add a scoop of extra barley, or serve it alongside a cozy cup of soup. All plants, all satisfying.

This was pretty darn good. I was quite surprised because I typically don’t like too much arugula and things that are strong lemon flavored, but this was really good. I would definitely make it again.
This was my absolute favorite salad so far in the Salad Challenge! I loved the chew of the barley, the crunch of the fennel and nuts, the sweetness of the sugar snap peas and the brightness of the vinaigrette. I couldn’t find fresh tarragon in my area, so I subbed 1-1/2 teaspoons of dried and it was just fine. It was very satisfying and I will definitely make this salad often to enjoy!
I really liked this one! It is so fun to experimenting new flavor combos you’d never think of and find you really like them!
On a roll… a salad a day! I’m trying and making things I never tried before. I was doubtful about today’s lemon arugula salad. But very surprised by it! I mixed spinach in with my arugula, because the arugula looked so skinny and lonely. I never ate raw fennel before and liked the smell and the crunch. I added some chopped celery too. I changed the dressing because after I made it, I wasn’t psyched by the taste. The dijon was too overwhelming, so I made it without and accidentally swapped basil for the recipe’s tarragon. I really liked the nutty flavor and texture of the barley in the salad. The chopped walnuts made it work! I may do this salad again!
I love happy accidents like swapping basil for tarragon and not realizing it. Sound delish!
I am late to the party due to out of town obligations but am so glad I made it. This salad is a new favorite! I loved the lemon tarragon dressing and reminds me of one my mom used to make only better! The tarragon kicked it up a notch.
This lemon arugula salad is a hit. Love the lemon combined with tarragon and glad to see barley in use. I can’t use oats, so barley is my staple grain. Fennel is a new flavor for me, so hope to see that show up again to learn another recipe that uses it.
