Oven Roasted Garlic Brussels Sprouts

If you’ve only met Brussels sprouts in their sad, steamed form, let me reintroduce you. These are oven–roasted, garlicky, straight-up crispy-edged little flavor bombs. Hot sheet pan, plenty of olive oil, smashed garlic that melts into everything, and a quick squeeze of lemon at the end. They go from “I’ll take a polite bite” to “I’m eating half the pan while standing at the stove in slippers” real fast.

My husband calls the crunchy leaves “chips” and raids the pan like a raccoon the second it comes out. The kiddo calls them “baby cabbages,” and I will never correct that. We made a huge tray last Sunday, and while I was being responsible and setting the table, both of them hovered like seagulls and destroyed the best bits. I pretended to be mad. I wasn’t. I was double-batching another tray before the oven even cooled.

I used to mince the garlic and toss it in right away—big mistake. It burned faster than my patience at 5 p.m. Now I smash the cloves with the knife, let them roast whole with the sprouts, and they turn jammy and sweet. The stray leaves that fall off? Don’t toss them. Those are the golden, lacy, crispy bits that start fights at my house. Also, putting the pan in the oven while it preheats means the sprouts hit a hot surface and sizzle on contact—fancy steakhouse treatment for vegetables. One time I tried maple syrup too early in the roast and turned the pan into candied chaos. Save sweet stuff for the last five minutes if you’re going there. And yes, parmesan on top is not optional in my kitchen. I said what I said.

Shopping Tips

– Vegetables: Look for small to medium Brussels sprouts that feel heavy and tight-leaved; avoid yellowing or lots of loose leaves.
– Fats & Oils: A good everyday olive oil works; skip ultra-fruity “finishing” oils for high-heat roasting. Avocado oil is a great swap.
– Spices: Grab a fresh head of garlic (firm, no green sprouts). If you’re out, a pinch of garlic powder at the end is a solid backup.
– Citrus: One bright, juicy lemon wakes everything up—zest first, then cut and squeeze.
– Cheese: Parmesan or pecorino adds a salty finish; the pre-shredded tub is fine, but freshly grated melts nicer.
– Frozen Aisle: Frozen Brussels can work in a pinch—roast from frozen on a hot pan and don’t crowd them; they’ll crisp up, promise.

Prep Ahead Ideas

– Trim and halve the sprouts up to two days ahead. Tuck them in a container lined with a dry paper towel to keep them from getting soggy.
– Peel and lightly smash garlic cloves in the morning; store in a little jar with a glug of oil so they mellow and perfume the oil.
– Mix a quick finishing bowl: lemon zest, chopped parsley, and grated parm. Cover and chill.
– On busy nights: in the morning, toss sprouts with oil, salt, pepper, and stow in the fridge. At dinner, dump onto a hot pan and roast.

✔Time-Saving Tricks

– Preheat the sheet pan inside the oven—instant sizzle, faster browning.
– Buy pre-peeled garlic or the little tubs of whole cloves when life is lifing.
– Use convection if you have it; knock a few minutes off and rotate the pan once.
– Don’t wash sprouts right before roasting; rinse earlier and make sure they’re super dry (water = steam = sadness).
– Let them sit the last minute in the hot pan with the oven off. That gentle finish makes them tender inside without burning.

✔Common Mistakes

– Overcrowding the pan: I did this for a holiday and ended up with steamed sprouts. Use two pans or roast in batches.
– Adding sweet stuff too early: Maple/honey at the start turns bitter and burns. Add in the final 3–5 minutes.
– Tiny minced garlic from the jump: it will burn. Smash cloves or add minced garlic at the end with the lemon.
– Not drying the sprouts: Wet sprouts won’t crisp. Pat them down like you mean it.
– Undersalting: They need a confident pinch. If you went too far, a squeeze of lemon and a handful of chopped parsley balance it out.

What to Serve It With

– Juicy roast chicken or rotisserie chicken and a quick pan gravy.
– Seared salmon or crispy tofu bowls over quinoa.
– Creamy polenta with these on top and a poached egg for chaos-brunch.
– Garlicky pasta and a glass of something cold and bossy.

✔Tips & Mistakes

– Hot oven, hot pan, cut sides down for max browning.
– Salt before roasting; finish with a tiny extra pinch and lemon after.
– If the garlic looks too dark, pluck it out early and toss it back in at the end.
– Don’t flip too soon—give them time to get that crust.
– If they’re pale, bump the heat for the last 3 minutes.

✔Storage Tips

Slide leftovers into a lidded container and stash in the fridge for up to 4 days. Re-crisp in a hot skillet or air fryer for a few minutes and they perk right back up. Cold from the fridge? Weirdly delicious tossed into a salad with feta and cranberries. I’ve also chopped them into scrambled eggs and called it breakfast, no regrets.

✔Variations and Substitutions

– Maple-balsamic finish: Toss with a drizzle of maple and a splash of balsamic for the last 3 minutes.
– Bacon or pancetta: Scatter diced pieces on the pan from the start; reduce added oil a bit.
– Heat lovers: Red pepper flakes or a swipe of Calabrian chili paste at the end.
– Crunch crew: Toasted almonds, pistachios, or hazelnuts are all amazing.
– Dairy-free: Skip parm, add toasted breadcrumbs and lemon zest for a savory finish.
– Soy-tangy: Finish with a tiny splash of tamari and rice vinegar, then sesame seeds.

Main Ingredients

• ▢ 1.5 lb Brussels sprouts, trimmed and halved
• ▢ 3 tbsp extra-virgin olive oil
• ▢ 2 tsp minced garlic
• ▢ 1 tsp kosher salt
• ▢ 0.5 tsp freshly ground black pepper
• ▢ 1 tbsp fresh lemon juice
• ▢ 2 tbsp finely grated Parmesan cheese optional
• ▢ 0.25 tsp crushed red pepper flakes optional, for a little heat

Instructions

Preparation Steps

• Heat oven to 425°F. Place a rimmed baking sheet on the middle rack while it heats.
• Trim stems, remove any tough outer leaves, and halve the Brussels sprouts. Pat them very dry.
• Toss sprouts with olive oil, garlic, salt, and pepper in a large bowl until coated.
• Spread sprouts on the hot baking sheet, cut sides down, in a single layer.
• Roast 15 minutes. Stir and roast 7–10 minutes more, until browned and tender.
• Finish with lemon juice. Toss with Parmesan and red pepper flakes if using, then serve hot.

Notes

Variation: Swap the lemon juice for 2 tsp balsamic vinegar or a drizzle of balsamic glaze. For extra crunch, roast a handful of panko with a teaspoon of oil during the last 3 minutes. Leftovers reheat well in a 400°F oven for 6–8 minutes or in an air fryer for 3–4 minutes.
