America's Test Kitchen Brussels Sprout Salad Recipe: Crispy Roasted Bites with Tangy Mustard Dressing

This America's Test Kitchen Brussels sprout salad recipe delivers crispy, caramelized edges that transform bitter sprouts into addictive bites. 🔥 After testing countless methods, we perfected a high-heat roasting technique that creates the ideal texture—tender yet crisp—while a tangy mustard dressing balances the richness. The secret lies in precise timing and temperature control, ensuring every sprout achieves that coveted golden-brown finish without burning.

The recipe begins with halved Brussels sprouts tossed in olive oil and salt, then roasted at 425°F until edges crisp and centers remain tender. This method preserves the sprouts' natural sweetness while developing deep, caramelized flavor. The dressing—a bright blend of Dijon mustard, apple cider vinegar, and honey—adds a zesty contrast that cuts through the richness, making each bite perfectly balanced.

What sets this salad apart is its restaurant-quality results at home, achieved through meticulous testing. The crispy edges hold their texture even after tossing with dressing, while the dressing's acidity enhances the sprouts' natural nuttiness. This isn't just a side dish—it's a flavorful main that pairs beautifully with grilled proteins or stands alone as a satisfying meal.

For extra depth, consider adding toasted walnuts or pomegranate seeds, but the base recipe remains foolproof. The key is patience—don't rush the roasting, and let the dressing marinate the warm sprouts for maximum flavor absorption. Ready in 30 minutes, this salad proves crispy Brussels sprouts can be both impressive and effortless.

Ingredients for america's test kitchen brussel sprout salad

High-heat roasting meets tangy precision—these ingredients craft crispy Brussels sprouts with restaurant-quality balance.

The Brussels sprouts are non-negotiable—look for small, compact sprouts with vibrant green leaves, not yellowing or wilted. Whole Foods or Trader Joe's carry the best quality, but any grocery store's fresh produce section works. Trim the ends and halve them lengthwise for even cooking. The olive oil should be extra-virgin—avoid the cheap stuff that burns easily. For the dressing, Dijon mustard adds depth, but Moutardier from specialty stores takes it to another level. Apple cider vinegar should be raw, unfiltered for maximum tang.

No Dijon mustard? Whole-grain mustard thinned with water works in a pinch, though flavor will differ. Substitute honey with maple syrup for a vegan option, though it won't caramelize the same way. The walnuts and pomegranate seeds are optional but add texture and visual appeal—toast walnuts in a dry pan until fragrant. For extra crispiness, pat the sprouts dry before roasting. The shallot can be swapped for 1/4 cup finely diced red onion if needed, though flavor will shift slightly. Fresh thyme is ideal, but dried at 1/3 the amount suffices in a bind.

Roasted sprouts stay crisp for 2-3 hours at room temperature, but refrigerate leftovers in an airtight container for up to 5 days. The dressing keeps for 1 week in the fridge—store separately to maintain texture. For meal prep, toss warm sprouts with dressing immediately before serving to preserve crispness. Portion dressing into small jars for easy tossing later. The walnuts and pomegranate seeds can be stored separately and added fresh before serving to maintain crunch.

Step-by-step instructions for perfectly crispy Brussels sprouts

Master this roasting technique and you'll achieve restaurant-quality texture every time.

Preheat your oven to 425°F with a rack positioned in the middle position. Trim the ends from the 1.5 lb Brussels sprouts and halve them lengthwise—this ensures even cooking. In a large bowl, toss the sprouts with 0.25 cup extra-virgin olive oil until they're evenly coated. Spread them in a single layer on two rimmed baking sheets, cut-side down, leaving ½-inch between each sprout.

Roast for 20 minutes until the edges begin to crisp and turn golden brown. Here's the thing—don't walk away. At 18 minutes, give the pans a quarter turn to ensure even browning. You want that perfect balance of crispy edges and tender centers. After 20 minutes, flip each sprout cut-side up and roast for another 5-8 minutes until they're uniformly deep golden brown with crispy edges.

Real talk: If your oven runs hot, reduce to 400°F to prevent burning. The sprouts are done when they release easily from the pan with a gentle nudge. Season immediately with 1.5 tsp kosher salt and 0.5 tsp freshly ground black pepper while still hot—this locks in the flavor.

While the sprouts roast, combine 2 tbsp Dijon mustard, 2 tbsp apple cider vinegar, and 1.5 tbsp raw honey in a small bowl. Whisk vigorously for 30 seconds until the honey dissolves completely and the mixture becomes smooth and glossy. This is your flavor foundation—don't skip the whisking or you'll end up with a grainy dressing.

Next, add 2 cloves minced garlic, 1 finely minced shallot, and 1 tsp chopped fresh thyme leaves to the bowl. Stir well to incorporate. The shallot adds subtle sweetness while the thyme brings an earthy depth that complements the Brussels sprouts beautifully. Taste the mixture and adjust seasoning with additional salt or pepper if needed.

Finally, slowly drizzle in the 0.25 cup extra-virgin olive oil while whisking continuously. This gradual addition emulsifies the dressing perfectly, creating a silky texture that clings beautifully to the crispy sprouts. The dressing should coat the back of a spoon but still pour easily—if it's too thick, add 1 tsp water to loosen.

Transfer the roasted Brussels sprouts to a large serving bowl while they're still warm. Drizzle the dressing over the top and toss gently with tongs until every sprout is evenly coated. The residual heat from the sprouts will help the dressing cling perfectly—don't skip this step. Let the salad sit for 2-3 minutes to allow the flavors to meld together.

Scatter 0.5 cup toasted walnuts and 0.25 cup pomegranate seeds over the top just before serving. The walnuts add a satisfying crunch while the pomegranate seeds introduce a bright, juicy contrast that cuts through the richness of the roasted sprouts. Toss one final time right before serving to distribute these toppings evenly.

This is the moment that matters: The contrast between the warm, crispy sprouts and the cool, tangy dressing creates a perfect temperature balance. Serve immediately while the sprouts are still crispy and the dressing is at its most flavorful. The salad keeps well in the refrigerator for up to 2 days, but the texture suffers after the first day—best enjoyed fresh.

Dietary considerations for this recipe

Gluten-Free Adaptations

This salad is naturally gluten-free, but watch the toppings! The optional toasted walnuts and pomegranate seeds are safe, but always check labels—some brands process nuts in gluten-containing facilities. For extra insurance, buy certified gluten-free walnuts from Bob's Red Mill or Trader Joe's. The dressing ingredients are inherently gluten-free, but if using a mustard substitute, verify it's labeled gluten-free. 🌱

Nut-Free Options

Skip the walnuts entirely for a nut-free version—the dressing and roasted sprouts still deliver bold flavor. For crunch, try toasted pumpkin seeds (¼ cup) or crispy fried shallots (2 tbsp). Both add texture without nuts. The pomegranate seeds remain a safe, vibrant garnish. Always store nut-free toppings separately to avoid cross-contamination.

Vegan Modifications

Replace the raw honey with maple syrup (1.5 tbsp) for a vegan dressing—though it won't caramelize as beautifully. Use vegan Dijon mustard (like Annie's) and ensure your olive oil is certified vegan. The roasted sprouts stay plant-based, but check your salt for anti-caking agents (Diamond Crystal is vegan-friendly). For extra protein, add ½ cup chickpeas roasted alongside the sprouts.

Lower-Carb Adjustments

This salad is already low-carb, but you can reduce it further by omitting the pomegranate seeds (they add ~2g net carbs per ¼ cup). For extra fat to stay satiated, increase the olive oil to ⅓ cup total in the dressing. The walnuts contribute healthy fats but ~4g net carbs per ½ cup—skip them if strict. The base recipe remains under 10g net carbs per serving without modifications.

Allergen-Friendly Tips

For soy-free diets, avoid Asian-style dressings that might cross-contaminate your prep area. If concerned about mustard allergies, swap Dijon for white wine vinegar + 1 tsp sugar (same acidity). For sesame-free kitchens, use plain olive oil instead of flavored varieties. Always wipe surfaces with a damp cloth between prep of allergenic and safe ingredients to prevent cross-contact. 💡
