Ingredients for balsamic roasted Brussels sprouts

Ingredients You’ll Need

  • brussels sprouts – one of my favorite seasonal veggies! You’ll need 2 pounds brussels sprouts for this recipe. Make sure to rinse the brussels sprouts well, trim off the ends and slice them into halves.
  • red onion – nothing better than roasted red onions!  You could also use white or yellow onions or shallots.
  • olive oil – I like to use a good olive oil that doesn’t have to be expensive, just make sure it’s cold-pressed and organic for the most flavor (in my opinion).
  • balsamic vinegar – this is the star of this dish and adds such a rich, tangy flavor!  Make sure to use a quality balsamic vinegar to get the most flavor.
  • honey – lightly sweetens these brussels sprouts without using any refined sugar, but you could also use maple syrup or other natural sweetener.
  • dijon mustard – adds a little zip of flavor!
  • mustard seeds – adds even more delicious mustard flavor.
  • salt + black pepper – needed to season and add flavor to the brussels sprouts.
  • optional additions – for even more flavor and texture, toss the finished Brussels sprouts with crispy bacon, toasted pecans or walnuts, dried cranberries, or a sprinkle of Parmesan cheese.

How to Make Balsamic Roasted Brussels Sprouts

  1. Prep the Brussels sprouts. Trim off the ends of the Brussels sprouts and slice them in half. Cut the red onion into slices and preheat your oven to 425°F.
  2. Season the vegetables. Toss the Brussels sprouts and red onion with olive oil, salt, black pepper and mustard seeds until evenly coated. Spread everything in an even layer on a parchment-lined baking sheet, placing as many Brussels sprouts cut-side down as possible.
  3. Roast until caramelized. Roast for 25 to 30 minutes, stirring once halfway through, until the Brussels sprouts are tender with crispy, browned edges.
  4. Make the balsamic glaze. While the vegetables roast, whisk together the balsamic vinegar, honey and Dijon mustard in a small bowl.
  5. Toss and serve. Drizzle the honey balsamic mixture over the hot roasted Brussels sprouts and onions, toss to coat and serve immediately.

Tips for the Best Roasted Brussels Sprouts

  • Don’t overcrowd the pan. Give the Brussels sprouts plenty of room so they roast and caramelize rather than steam.
  • Place them cut-side down. Starting the Brussels sprouts cut-side down against the baking sheet helps create those crispy, golden-brown edges.
  • Use high heat. Roasting at 425°F helps the Brussels sprouts become tender on the inside while getting beautifully caramelized on the outside.
  • Choose similar-sized sprouts. Cut larger Brussels sprouts into quarters if needed so everything cooks evenly.
  • Add the balsamic glaze after roasting. Tossing the Brussels sprouts with the glaze once they’re cooked prevents the honey from burning in the oven.
  • Serve them right away. Roasted Brussels sprouts have the best crispy texture when they’re fresh from the oven.

Frequently Asked Questions

Do you need to blanch Brussels sprouts before roasting?

No! There’s no need to blanch Brussels sprouts before roasting them. Roasting them directly in the oven at high heat gives them tender centers and crispy, caramelized edges.

Why aren’t my roasted Brussels sprouts crispy?

The most common reason is overcrowding the baking sheet. Spread the Brussels sprouts in a single layer with plenty of space between them and place them cut-side down for the best caramelization.

Can I make balsamic roasted Brussels sprouts ahead of time?

Yes. You can trim and halve the Brussels sprouts and slice the red onion up to 2 days ahead of time. Store them in airtight containers in the refrigerator, then season and roast when you’re ready to serve.

Can I use maple syrup instead of honey?

Absolutely. Substitute pure maple syrup for the honey in equal amounts. It pairs especially well with the balsamic vinegar and makes this recipe vegan.

Can I make these Brussels sprouts in the air fryer?

Yes. Toss the Brussels sprouts with the olive oil and seasonings and air fry at 375°F until tender and crispy, shaking the basket halfway through. Depending on the size of your air fryer, you’ll likely need to cook them in batches. Toss with the honey balsamic glaze after cooking.

Prepping and Storage

  • To Prep: Trim and halve the Brussels sprouts and slice the red onion up to 2 days ahead of time. Store them in separate airtight containers in the refrigerator until ready to roast.
  • To Store: Store leftover balsamic Brussels sprouts in an airtight container in the refrigerator for up to 4 days.
  • To Reheat: For the best texture, reheat the Brussels sprouts in a 350°F oven or air fryer for a few minutes until warmed through and crispy. You can also microwave them, but they won’t be as crisp.

      Oh these get nice and crisp! If you wanted them a little extra crispy, pop them under the broiler for a minute or two after roasting 🙂
