This delicious roasted brussels sprouts recipe is ready in just 20 minutes! The trick to flavorful, crisp bites on the outside with tender centers involves two cooking methods: steaming and roasting, both of which happen in the oven.
Recipe Science
- Use only 1 tablespoon of water for 2 pounds of sprouts. This small amount creates superheated steam to tenderize the interior.
- Steam the brussel sprouts to activate pectin methylesterase, which strengthens cell walls, keeping them firm and tender, not mushy.
- Roast the sprouts at 500ºF to drive off moisture. The hot sheet pan quickly caramelizes the sprouts’ surfaces for crispy bites.

“FINALLY a recipe that solved my roasting problem. Seems obvious to steam them first, but I never would have thought of this technique. It worked perfectly, and the Brussels came out soft on the inside, roasted and crispy on the outside. We will be using this as the base for all our roasted veggie recipes.”—Joetta
Why It Works
Brussels sprouts may look like bland mini cabbages, and many avoid them due to their potential for bitterness or a rubbery, mushy texture. But with the right technique, these little buds can be full of flavor. I’ll show you how to bring out their best by roasting them in the oven.
Roasting creates a high-heat environment that quickly generates new surface flavors and colors due to caramelization. However, the hot, dry heat alone doesn’t firm up or tenderize the insides. The sprouts need steam to pre-cook them first before roasting. It’s a gourmet side dish that’s easy to prepare on weekdays or holidays like Thanksgiving.
Ingredients You’ll Need
- Brussels Sprouts: Brussels sprouts are cruciferous vegetables that can often be found year-round, although their peak season is from September to February. They may be attached to their stalks or sold loose, trimmed, and packaged. Look for green leaves that are firm to the touch and compact. Typically, smaller sprouts are sweeter. Check the stems for browning and cracks. Avoid those pieces. For even cooking, choose ones that are similar in size.
- Oil: Choose a neutral-tasting, high smoke point oil to withstand the eventual roasting temperatures. I use extra-virgin olive oil for its fruity taste.
- Water: Only 1 tablespoon of water is necessary for 2 pounds of sprouts. The water turns into superheated steam, which cooks the sprouts’ interior.
- Seasoning: Simply toss the sprouts with salt and pepper to enhance their flavor.

Ingredient Substitutions
This roasted Brussels sprouts recipe is easy to customize! Try these delicious options:
- Oil Swap: Use coconut oil, avocado oil, ghee, or clarified butter. The roasting temperature is very high, so adding melted butter before serving is best.
- Add Meat: Make bacon Brussels sprouts by chopping up oven-roasted bacon and sprinkle it on top. Try my sauteed brussel sprouts with bacon!
- Add a Sauce: Drizzle on a balsamic vinegar glaze for a sweet and tangy combo. Add tahini sauce for a creamy sesame flavor. Dip in ranch dressing to toss with Italian dressing.
- Add Cheese: Freshly grated parmesan cheese or gruyere for a nutty flavor.
- Seasoning: Sprinkle with garlic powder or onion powder. For spiciness, add red pepper flakes.
- Add Crunch: Add chopped nuts like walnuts or pecans for crunch. Top with toasted bread crumbs.
How to Roast Brussel Sprouts
Step 1: Preheat Oven
Position your oven rack in the upper-middle section and preheat to 500ºF (260ºC). This helps steam the vegetables first, then the high heat is key to quickly caramelizing the Brussels sprouts, giving them that perfect golden-brown finish.
Step 2: Prepare the Brussels Sprouts
For this oven-roasted Brussels sprouts recipe, try to find ones that are 1 ½ inches long. Cut the sprouts in half lengthwise. If smaller than 1 inch, keep them whole. Cut them into quarters if you have jumbo-sized sprouts larger than 2 ½ inches. Trim off any browned and bruised outer leaves.
Step 3: Season
In a large bowl, toss the Brussels sprouts with olive oil, water, salt, and pepper until evenly coated.
Step 4: Steam
Arrange the Brussels sprouts cut-side down in a single layer on a large, rimmed baking sheet. Cover the pan tightly with foil to trap steam and help it cook through evenly. The 10-minute oven steaming process minimizes moisture loss and makes the sprouts taste slightly sweet instead of bitter. When you remove the foil, the buds will be bright green and firm yet tender.
Ingredient Chemistry: Steaming keeps them firm and tender by activating the enzyme pectin methylesterase at 120 to 160ºF (49 to 71ºC). The enzyme helps the link with the calcium ions to strengthen the bonds in the cell walls so that the sprouts don’t become mushy. The cooking method is similar to blanching but saves you an extra pot to wash.
Step 5: Roast
After steaming the sprouts and pre-cooking the interiors, it’s time to drive off the moisture on the surface. Roasting at 500ºF (260ºC) allows the exposed sprouts to caramelize, adding extra flavor.
The sheet pan holds heat more efficiently than the hot air in the oven, so anything touching the metal will brown more quickly and develop more flavor. After about 9 to 12 minutes, the surface sets into a deep golden brown color with crispy edges.
Step 6: To Serve
Season with salt and pepper to taste, and serve the crispy Brussels sprouts warm for the best flavor.
Frequently Asked Questions
Using a two-step method, brussels sprouts should be covered and steamed in the oven for 10 minutes, then roasted until crispy for 9 to 12 minutes.
For pieces 1 inch and more extensive, then they should be halved. More contact with the pan yields a better golden, crispy texture on the surface. Smaller pieces should be left whole.
Pre-cooking helps to soften the interior without overcooking. It activates a particular enzyme to make the cell walls sturdy yet tender. Either briefly blanching or steaming is recommended before roasting.
