Balsamic roasted brussels sprouts turn bitter little cabbages into sweet, caramelized bites with crisp, browned leaves, then finish with a splash of balsamic vinegar and a shower of grated Parmesan.
They need only a baking sheet and about thirty five minutes, and the oven does nearly all of the work. Halve the sprouts, toss them with oil and seasoning, roast them cut side down, and serve them hot.

Why This Balsamic Roasted Brussels Sprouts Recipe Works
Roasting at high heat caramelizes the natural sugars in the sprouts, which tames their bitterness and gives the cut sides a deep, nutty brown crust.
Placing the sprouts cut side down on the pan gives them direct contact with the hot metal, so they brown evenly while the insides stay tender.
Balsamic vinegar adds a sweet, tangy gloss, and Parmesan sprinkled on after roasting adds a salty finish that makes the dish taste rich.
Ingredients for Balsamic Roasted Brussels Sprouts
- For the sprouts: one pound of fresh brussels sprouts, trimmed and halved, tossed with olive oil, coarse sea salt, black pepper, and garlic powder.
- For the finish: a tablespoon of balsamic vinegar drizzled over the hot sprouts, and a handful of freshly grated Parmesan cheese on top.
Brussels sprouts. Choose small to medium sprouts with tight, bright green leaves, and avoid frozen ones, which turn soft in the oven.
Olive oil. Toss the sprouts until every surface shines, since the oil carries the heat that browns the leaves.
Salt and pepper. Coarse sea salt sticks to the oily surface, and freshly ground pepper adds a gentle bite.
Garlic powder. It coats evenly without burning, unlike fresh garlic, which can turn bitter at high heat.
Balsamic vinegar. A single spoonful goes a long way, and it should be added after roasting so it does not scorch.
How to Make Balsamic Roasted Brussels Sprouts
1. Heat the oven. Heat the oven to 425 degrees F and set out a large rimmed baking sheet.
2. Trim the sprouts. Wash the brussels sprouts, trim the stems, and cut them in half from top to bottom.
3. Season them. Toss the sprouts in a bowl with the olive oil, salt, pepper, and garlic powder until evenly coated.
4. Arrange the pan. Place the sprouts in a single layer on the baking sheet with the cut sides down.
5. Roast until browned. Roast for twenty two to twenty five minutes, turning once halfway through, until toasted and deeply browned at the edges.
6. Finish and serve. Drizzle with the balsamic vinegar, sprinkle with Parmesan, and serve hot.
How to Serve Balsamic Roasted Brussels Sprouts
Serve the sprouts hot as a side for roasts, steak, and fish. They pair well with lemon garlic baked halibut, herb butter ribeye steak, creamy garlic parmesan orzo, and an Italian house salad.
How to Store and Reheat Balsamic Roasted Brussels Sprouts
Cool the sprouts within two hours and keep them in a covered container in the refrigerator for up to four days. Reheat on a hot baking sheet or in an air fryer until they reach 165 F, which restores some crispness. The microwave makes them soft, so use it only when you are short on time.
Tips and Variations for Balsamic Roasted Brussels Sprouts
Dry the sprouts. Pat washed sprouts completely dry, since extra water causes steaming instead of browning.
Cut side down. Setting the flat side against the pan gives the deepest browning and a stronger flavor.
Do not crowd. Use two pans if needed, since crowded sprouts steam and turn soft rather than crisp.
Add vinegar late. Balsamic vinegar burns easily, so drizzle it over the sprouts after they come out of the oven.
Flag the allergens. Parmesan contains milk, so label the dish clearly or leave it off for guests with dairy restrictions.
Add extras. Crumbled bacon, dried cranberries, or toasted nuts all pair well with the sweet and savory sprouts.
Wash safely. Rinse the sprouts under cool running water and use a clean board for cutting.
Check trusted guidance. Read the FDA safe food handling guidance for tips on fresh vegetables.
