How to Roast Brussels Sprouts at 425°F

Roast Brussels sprouts at 425°F for crisp edges and tender centers, with simple timing, pan placement, and finishing tips.

Quick reference

Oven: 425°F Fully preheat
Small halves: 20–23 minutes Check early
Medium halves: 23–27 minutes Most common
Large halves: 27–30 minutes May need longer
Best setup: Single layer Cut-side down

Prep the Brussels sprouts

Trim the dry stem ends and remove any loose or damaged outer leaves. Halve each sprout from stem to tip, aiming for pieces of similar size so they finish together. Rinse if needed, then dry thoroughly with a clean towel. Excess water can soften the sprouts instead of helping them brown.

Use sprouts of similar size.
Keep very small sprouts whole only if necessary.
Do not crowd wet vegetables on the pan.

Season and arrange

Toss the dry halves with olive oil, salt, and black pepper. Use enough oil to lightly coat the cut surfaces without leaving them greasy. Arrange the sprouts in a single layer on a sturdy sheet pan, with the cut-side down. Leave a little space between pieces; packed vegetables steam rather than roast.

Cut-side down encourages browning.
Use a second pan if the sprouts are crowded.
Parchment is optional but can reduce sticking.

Roast at 425°F

Place the pan in a fully preheated 425°F oven. Roast Brussels sprouts for about 20 to 30 minutes, depending on their size and your oven. Small halves may be ready near 20 minutes; larger halves can take closer to 30. Turn or shake the pan once if browning is uneven, but keep most of the cut-side contact with the pan.

Start checking at 20 minutes.
Look for browned, crisp edges.
A knife should slide easily into the thickest part.

Finish with acid

Transfer the roasted sprouts to a serving bowl and finish with a small splash of lemon juice or vinegar after roasting. The acid brightens the browned flavor without interfering with crisping in the oven. Taste, then adjust with more salt, pepper, or a little grated Parmesan if desired.

Add lemon juice just before serving.
Try sherry, red wine, or balsamic vinegar.
Serve immediately for the crispest edges.

Quick troubleshooting

If the sprouts are pale, they may be crowded, too wet, or the oven may not have been fully heated. If the leaves darken before the centers soften, use a slightly lower rack position or cover the pan loosely for the final few minutes. Oven performance and sprout thickness vary, so use tenderness and browning as the final cues rather than time alone.

Pale: spread the pieces farther apart.
Firm centers: roast a few minutes longer.
Burning leaves: check sooner and adjust the rack.
