Roasted Brussels sprouts make an excellent side dish. Tossed with butter, capers and a touch of vinegar, they become savory, tangy and irresistibly delicious.
What Ingredients Make Roasted Brussels Sprouts Taste Amazing?
- 450 g Brussels sprouts (about 1 lb), trimmed and halved
- 2 Tbsp salted butter, melted
- 1 tsp garlic powder
- 1 tsp white vinegar
- ½ tsp salt
- ½ tsp ground black pepper
- 2 Tbsp capers, drained
Do Capers Go Well With Brussels Sprouts?
Yes. Capers add a briny, lemony pop that brightens the natural, slightly bitter flavor of cruciferous vegetables like Brussels sprouts. Salt and acid are classic partners for cabbage-family vegetables, and a little butter brings richness to balance the tang. The combination of butter, vinegar and capers is simple but effective: the fat carries flavor while the capers and vinegar provide contrast.
This flavor pairing is in the same spirit as modern food-pairing thinking—matching contrasting tastes and textures to create a memorable side dish.
How To Roast Brussels Sprouts In The Oven
Preheat a fan-forced oven to 200°C (400°F). Line a 15-inch x 10-inch (38 cm x 25 cm) baking sheet with parchment paper, unless you want extra-crispy, caramelized edges—if so, skip the parchment so the sprouts can brown directly against the pan.
Give the sprouts room: overcrowding prevents browning. Arrange them cut side down on the tray with a little space around each piece. If your pan is small, use two trays on separate racks with good airflow.
- Place the halved Brussels sprouts in a medium bowl. Add the melted butter, garlic powder, white vinegar, salt and black pepper. Toss until evenly coated.
- Spread the sprouts on the baking sheet, cut side down, in a single layer.
- Roast for 30 minutes, then remove the pan and turn each sprout over. Scatter the capers over the pan and return to the oven for another 15 minutes, or until the sprouts are tender inside and well browned outside.
- Remove from the oven and rest for 5 minutes before serving so the flavors settle.

Tip
Give the sprouts room on the pan. If they are too close together they will steam instead of crisping. For the crispiest results, roast on an unlined pan so the cut sides can caramelize directly on the metal, or spread the recipe across two trays if needed.

Tips & Notes
- Store leftovers in the refrigerator for up to 4 days or freeze for up to 2 months.

- Do not overcrowd the pan. If the sprouts are too close together they will steam rather than brown—use two pans if necessary.
