Arugula and Brussels Sprout Salad Recipe: Peppery Bite Meets Crispy Roasted Sprouts

This arugula and Brussels sprout salad recipe transforms humble ingredients into a restaurant-quality dish where crispy roasted sprouts meet peppery arugula in perfect harmony. The secret lies in high-heat roasting that caramelizes the sprouts' edges while preserving their tender centers—a technique that elevates this salad from simple to showstopping.

I developed this recipe after realizing store-bought versions never captured the depth of homemade roasting and fresh dressing.

What sets this salad apart is the balance of textures and flavors: crispy Brussels sprouts with their smoky char, the sharp peppery bite of arugula, and a creamy lemon vinaigrette that ties everything together.

The roasting process takes just 15 minutes and requires no special equipment, while the dressing comes together in minutes with pantry staples. This isn't just another salad—it's a complete meal with protein-rich nuts and optional cheese for added satisfaction.

The result is a visually stunning dish that's just as impressive on the plate as it is delicious. Golden roasted sprouts contrast beautifully with vibrant arugula, while the dressing creates a glossy finish that makes every bite irresistible.

This salad holds up well for meal prep, making it perfect for busy weeknights or impressive gatherings when you want to serve something that feels special without spending hours in the kitchen.

Pair it with grilled chicken or fish for a complete meal, or serve it alongside roasted proteins for a well-rounded vegetarian option. The crispy texture of the sprouts ensures each bite is satisfying, while the peppery arugula keeps things fresh and bright.

Here's how to create this perfect balance of flavors and textures in your own kitchen.

Ingredients for arugula brussel sprout salad

Crispy roasted sprouts meet peppery arugula in this restaurant-quality salad—just 12 ingredients, maximum flavor.

The Brussels sprouts are the star here. Look for small, firm sprouts—they roast more evenly. Trader Joe's and Whole Foods have the best quality, but any grocery store's fresh produce section works. Halving them lengthwise ensures they crisp up perfectly. Don't skip the trimming—those tough ends ruin the texture. For extra flavor, toss them with olive oil and salt before roasting. That's where the magic happens—high heat caramelizes the edges while keeping the centers tender. Trust me on the 450°F oven temp—any lower and they'll steam instead of crisp.

No fresh arugula? Baby spinach works in a pinch, but the peppery bite is essential. The dressing can be made ahead—just store it in a jar and shake before using. Substitute maple syrup for honey if you're avoiding it, though the honey adds that perfect balance. For the walnuts, pecans or almonds work too, but walnuts have the best texture contrast. The Parmesan is optional, but freshly grated makes all the difference—pre-grated tastes like sawdust. And if you're feeling fancy, add a pinch of red pepper flakes to the dressing for a little kick.

Roasted sprouts stay crispy for about 3 days in the fridge if stored in an airtight container. The dressing keeps for 5 days, but the arugula wilts fast—add it just before serving. Portion the nuts and cheese separately so you can customize each serving. This salad reheats beautifully—perfect for meal prep. Just toss with a little extra dressing to revive the greens. And if you're serving a crowd, double the dressing and make extra nuts. You'll want seconds anyway.

Step-by-step instructions for arugula and Brussels sprout salad

Transform simple ingredients into a showstopping salad with perfect crispy sprouts and vibrant peppery greens.

Preheat your oven to 425°F and line a large baking sheet with parchment paper. Trim the ends off the 1.5 lb Brussels sprouts and halve them lengthwise. Spread them out in a single layer on the baking sheet, cut-side down.

Drizzle the sprouts evenly with 2 tablespoons of the 0.5 cup extra-virgin olive oil (about half the total amount) and sprinkle with 0.75 tsp salt and 0.25 tsp black pepper. Toss gently to coat, making sure each half gets an even layer of oil and seasoning. Roast for 20-25 minutes until the edges are deep golden brown and crispy, stirring halfway through for even cooking.

Here's the thing—don't walk away during the last 5 minutes. The sprouts go from perfect to burnt fast at this temperature. You want them tender inside with crispy, caramelized edges. When they're done, transfer them to a plate and let them cool slightly while you prepare the rest of the salad.

In a medium bowl, combine the 0.33 cup lemon juice, 1 tbsp Dijon mustard, 2 tbsp honey, 2 minced garlic cloves, and the remaining 3 tablespoons extra-virgin olive oil. Whisk vigorously for about 30 seconds until the mixture is smooth and emulsified.

Add the remaining 0.75 tsp salt and 0.25 tsp black pepper to the dressing. Taste it right away—you want a perfect balance of bright lemon, tangy mustard, sweet honey, and garlicky depth. If it needs more acidity, add a splash more lemon juice. If it's too sharp, stir in a tiny bit more honey. This is where the magic happens!

Real talk: Don't skip tasting the dressing. It's the secret to making this salad truly exceptional. The dressing should coat the back of a spoon but still be pourable. If it's too thick, whisk in 1-2 teaspoons water to loosen it slightly.

In a large salad bowl, combine the 6 cups arugula with the cooled roasted Brussels sprouts. The peppery arugula and crispy sprouts alone create an amazing contrast—don't skip this step! Sprinkle the salad evenly with the 0.5 cup toasted walnuts and 0.25 cup freshly grated Parmesan cheese.

Drizzle about half of the dressing over the salad and toss gently with tongs or a large spoon. You want everything evenly coated but not smashed. The walnuts should still hold their shape, and the arugula should maintain its vibrant color. If the salad looks dry, add a little more dressing—just enough to moisten the greens without making it soggy.

Here's where it gets fun—taste the salad before serving. You might want to add more salt, a touch more honey, or even a pinch of black pepper to perfect the flavors. This is your chance to adjust based on your personal taste preferences.

Just before serving, drizzle the salad evenly with the 1 tbsp balsamic vinegar. Watch as it creates beautiful dark streaks that contrast beautifully with the bright greens and golden sprouts. The balsamic adds a sophisticated tang that ties all the flavors together.

Gently toss the salad one final time to distribute the balsamic evenly. Serve immediately while the Brussels sprouts are still crispy and the dressing is at its best. This salad tastes even better when enjoyed fresh—every component should be at room temperature for optimal texture and flavor.

Don't be surprised if this becomes your go-to salad for dinner parties. The combination of crispy, caramelized sprouts, peppery arugula, and that perfect dressing is simply irresistible. Plus, it's a great way to use up those Brussels sprouts before they go bad!

Storing and reheating this recipe

Refrigerator Storage

Store your roasted Brussels sprouts in an airtight container with parchment paper between layers to maintain crispness for up to 3 days. Keep them in the fridge at 40°F or below—the high heat from roasting helps preserve texture longer than raw sprouts.

The arugula, however, wilts quickly, so add it fresh just before serving. 🥬

Freezer Storage

For longer storage, freeze roasted Brussels sprouts in a single layer on a baking sheet first to prevent clumping, then transfer to a freezer bag with all air removed.

They'll keep for 2 months—thaw overnight in the fridge before using. The dressing can be frozen too, but add a splash of water when thawing to restore consistency.

Reheating Roasted Sprouts

Revive crispiness by spreading cooled sprouts on a baking sheet and heating at 400°F for 5-7 minutes. For a quick fix, toss them in a dry skillet over medium heat for 2-3 minutes—just until warmed through. Avoid microwaving, as it makes them soggy. 🔥

Dressing Refresh

If the dressing separates after refrigeration, whisk vigorously with 1 tsp warm water to re-emulsify. For extra brightness, add a splash of fresh lemon juice. Store dressing in a small jar with a tight lid to prevent oxidation, and shake before using.

Meal Prep Assembly

Prep components separately for maximum freshness: roast sprouts, make dressing, and toast nuts ahead. Assemble the salad just before serving by combining arugula, sprouts, and dressing. Keep Parmesan and balsamic vinegar separate until the last minute to prevent sogginess. This method keeps everything crisp and vibrant. ✨

Portioning Tips

Divide the salad into individual containers with dressing on the side to customize portions. Store arugula separately in a separate container with a paper towel to absorb moisture. Reassemble by adding fresh greens and dressing when ready to eat—this ensures the best texture every time. 💡
