Yield
Serves 4 as a side dish
Difficulty Level
Easy
Ingredients
- 1 pound Brussels sprouts, trimmed and halved
- 3 tablespoons extra virgin olive oil
- 1 teaspoon flaky sea salt
- ½ teaspoon freshly ground black pepper
- 1 tablespoon Dijon mustard
- 2 tablespoons apple cider vinegar
- 1 teaspoon honey (or maple syrup for vegan option)
- 1 small clove garlic, finely minced
- 2 tablespoons extra virgin olive oil (for the vinaigrette)
- Optional: toasted sliced almonds or crispy pancetta for garnish
Instructions
- Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup and even roasting.
- Select Brussels sprouts that are firm, bright green, and small to medium in size for optimal crispiness.Larger sprouts tend to be soggier inside.
- Toss the halved sprouts with 3 tablespoons olive oil, flaky sea salt, and freshly ground black pepper, coating them evenly to encourage caramelization.
- Arrange the sprouts cut-side down on the prepared pan-this contact with the pan helps create those coveted golden-brown edges.
- Roast for 20-25 minutes, flipping halfway through to ensure even browning but keep the cut side crisp. Watch them closely near the end; when they’re deeply caramelized with crispy tips, they’re ready.
- While the sprouts roast, whisk together Dijon mustard, apple cider vinegar, honey, and minced garlic in a small bowl. Slowly drizzle in 2 tablespoons of olive oil while whisking vigorously to emulsify into a tangy mustard vinaigrette.
- Remove the Brussels sprouts from the oven and promptly toss them with the vinaigrette. The warmth of the sprouts will soften the sharpness of the mustard and deepen the flavors.
- Plate your creation, garnishing with toasted sliced almonds for a nutty crunch or crispy pancetta for an indulgent twist.
Tips for Success
- Choose small to medium sprouts: The smaller, the better for crisp edges and tender centers.
- Dry thoroughly: After washing, pat the sprouts entirely dry. Moisture is the enemy of crispness.
- Don’t overcrowd the baking sheet: Give them space so they roast rather than steam.
- Adjust roasting time: All ovens vary; watch for that perfect golden crust.
- Vinaigrette variations: Swap apple cider vinegar for sherry vinegar for a deeper, sweeter note or add a pinch of smoked paprika for warmth.
- Make-ahead tip: Prepare the vinaigrette a day ahead to let flavors meld. Store sprouts and dressing separately and toss right before serving.

Q&A
Q&A: Crisp Roasted Brussels Sprouts with Tangy Mustard Vinaigrette
Q: What makes Brussels sprouts “crisp” when roasted?
A: Achieving crisp Brussels sprouts starts with high heat and dry roasting. By halving the sprouts and spreading them out on a baking sheet-cut side down-you allow maximum caramelization. This direct heat crisps up the edges while keeping the insides tender. Avoid overcrowding the pan to ensure every sprout gets a golden, crunchy makeover.
Q: How does roasting change the flavor of Brussels sprouts?
A: Roasting transforms Brussels sprouts from their raw, slightly bitter state into something sweeter, nuttier, and deeply savory. The Maillard reaction-the chemical browning during roasting-creates those irresistible toasted notes and a satisfying depth of flavor that steaming or boiling simply can’t match.
Q: Why pair the sprouts with a tangy mustard vinaigrette?
A: The mustard vinaigrette adds a bright, zesty counterpoint to the warm, caramelized sprouts. Its acidity cuts through the slight bitterness and roasted oils, lifting each bite with a refreshing tang. The mustard also enhances the earthy flavors, tying everything together with a subtle kick.
Q: What ingredients typically go into this mustard vinaigrette?
A: A classic tangy mustard vinaigrette combines Dijon mustard, sharp vinegar (like apple cider or white wine), a touch of honey or maple syrup for balance, extra virgin olive oil, and a pinch of salt and pepper. Sometimes garlic or shallots join the mix for added depth.
Q: Can I make this dish vegan and gluten-free?
A: Absolutely! Brussels sprouts roasted in olive oil with a mustard vinaigrette are naturally vegan and gluten-free. Just be sure your mustard and vinegar haven’t been processed with any animal products or gluten-containing ingredients-though most are safe by default.
Q: What are some creative serving suggestions for this dish?
A: Serve these crisp sprouts as a vibrant side to roasted chicken or grilled salmon, toss them into warm grains like quinoa or farro, or pile them onto toasted bread as a tangy bruschetta topping.They also shine when sprinkled with toasted nuts,crumbled vegan cheese,or pomegranate seeds for extra texture and flavor bursts.
Q: How far ahead can I prepare this dish?
A: Roasted Brussels sprouts are best enjoyed fresh, crispy straight from the oven. However, you can roast them a few hours in advance and reheat gently in a hot oven to regain some crunch. The mustard vinaigrette is also great made ahead-just toss the sprouts with it right before serving to preserve texture.
Q: Any tips for selecting the best Brussels sprouts?
A: Choose small to medium-sized sprouts for tenderness and even roasting. Look for bright green, firm heads without yellowing leaves or blemishes. Freshness matters-sprouts that smell fresh and feel firm will roast up crisp and flavorful.
