Can I skip the microwave step and just roast these?
Yes. Toss brussels sprouts with oil and seasonings, roast at 400°F for 25–30 minutes, shaking halfway. The microwave step shortens total time by precooking them, but roasting alone works fine.
How do I know when the brussels sprouts are done?
They're ready when the outer leaves are dark golden-brown and crispy, and a fork easily pierces the center. The edges should be slightly charred.
What do Calabrian chili peppers taste like?
They're mildly spicy with a fruity, slightly sweet undertone. If you don't have them, use red pepper flakes or swap for smoked paprika for a milder heat.
Can I make this ahead for a holiday dinner?
Prep and cut the brussels sprouts up to 2 days ahead. Cook them just before serving for best crispiness, though leftovers reheat well in a 350°F oven for 8–10 minutes.
How do I scale this recipe?
Double or halve all ingredients. Cooking time may increase slightly with larger batches; check for doneness visually rather than relying on time alone.
