Spicy Brussels sprouts done this way are halved sprouts seared cut-side down in a hot skillet until the faces go deep brown, finished in a 425°F oven until tender, then tossed off the heat in a sticky sweet chili glaze and topped with quick-pickled Fresno peppers and micro cilantro. It is the side Hell's Kitchen in Washington, DC lists next to its steaks, and at home it takes about 35 minutes, with the pickled peppers made first so they have time to soak. The glaze is sweet, hot and sour at once, which is exactly what a Brussels sprout needs.
The Hell's Kitchen Roasted Brussels Sprouts, Made at Home
Hell's Kitchen's Washington, DC restaurant lists roasted Brussels sprouts with a chili glaze, pickled Fresnos and micro cilantro among the sides on its official menu, marked dairy-free, and this recipe rebuilds that plate from those four parts. The restaurant does not publish its recipe, so the glaze here is a home version built from pantry staples: honey for sweetness, chili garlic sauce for heat, rice vinegar and lime for sourness, and a little soy sauce for salt and depth. It stays dairy-free as written. The other DC dishes, and how the seven US locations differ, are laid out in our Hell's Kitchen menu guide.
On the menu it sits beside the 20-ounce Prime bone-in ribeye, and the two make a natural pair at home too: the sprouts roast at 425°F while a thick steak cooks low and slow, and the sharp glaze cuts the richness of a fatty cut. Our bone-in ribeye recipe covers that steak, with the roasted garlic, maitake and peppercorn sauce from the same plate.
How to Make Spicy Brussels Sprouts That Brown Instead of Steam
For spicy Brussels sprouts with a real crust, halve them, dry them, and lay every half cut-side down in a hot 12-inch skillet with a film of oil, then leave them alone for 4 to 6 minutes before the pan goes into a 425°F oven. Browning, the Maillard reaction, only starts once a food's surface gets above about 285°F, as the science of the Maillard reaction explains, and a wet surface cannot get past 212°F, the boiling point of water. Rinsed sprouts that go into the pan damp spend their first minutes steaming. Pat them dry with a towel first.
The flat cut face is the whole reason for halving them. Pressed against hot metal it browns evenly and deeply, while a whole sprout only touches the pan at one point and browns in a spot. Keep them in one layer with a little space around each half; crowd the pan and the water they release has nowhere to go, the pan temperature drops, and they stew. Two pounds is about the limit for a 12-inch skillet; for more, sear in batches or use the sheet-pan method in the table below. The loose outer leaves that fall off while you trim go in too. They turn into thin, crisp, salty chips in the oven, and nothing gets thrown out.
Gordon Ramsay's order of operations applies here as it does to a steak: hot pan first, then the oil, then the food, and nothing goes in unless it sizzles. Season the sprouts with salt before they go in so the seasoning sits on the surface that browns. After the sear, 10 to 12 minutes in the oven cooks the dense core until a paring knife slides in with no resistance, while the cut face keeps browning against the hot pan. A skillet that is oven-safe at 425°F does both jobs without moving the sprouts.

Why Brussels Sprouts Taste Bitter, and How the Glaze Fixes It
Brussels sprouts taste bitter because of glucosinolates, sulfur compounds the plant makes to defend itself against pests, and two of them, sinigrin and progoitrin, are the ones linked to the bitter taste. According to a Chemistry & Industry report on sprout breeding, seed company Syngenta began breeding milder varieties in the early 1990s and released its first sweeter sprout, Maximus, in 1994; even the "classic" sprouts sold now are less bitter than the ones many adults remember from childhood. People also differ in how strongly they taste these compounds, which is why one person's mild sprout is another's bitter one.
Cooking method changes the rest. When a sprout is cut or chewed, an enzyme called myrosinase meets the glucosinolates and turns them into sharper, mustardy compounds, the Linus Pauling Institute at Oregon State University explains; boiling inactivates that enzyme and leaches the glucosinolates into the water far more than steaming, microwaving or stir-frying does. Long boiling is also what gives sprouts their sulfurous cabbage smell and grey-green color. Roasting avoids both: the outside browns, the natural sugars caramelize from around 320°F, and the sprout tastes nutty and sweet instead of sharp.
The glaze handles whatever bitterness is left. Sweetness from honey, sourness from vinegar and lime, salt from soy sauce and the heat of chili all compete with bitterness on the tongue, so a sprout with a little edge tastes balanced rather than harsh once it is coated. It is the same reason bacon, balsamic and maple are classic Brussels sprouts partners: salt, acid and sugar.
The Sweet Chili Glaze: Honey, Chili, Vinegar and Soy
The chili glaze for spicy Brussels sprouts is 3 tablespoons of honey, 1½ tablespoons of chili garlic sauce or sambal oelek, 1 tablespoon of rice vinegar and 2 teaspoons of soy sauce, simmered for a minute or two in a small saucepan until it turns slightly syrupy, then finished with lime juice off the heat. Taste it before it goes on: it should be distinctly sweet, then hot, then sour. Add more chili sauce for heat, or a little more honey if your chili sauce is very sharp. Tamari keeps it gluten-free.
Toss the sprouts in the glaze after they come out of the oven, not before they go in. Honey is mostly sugar, and sugar caramelizes from about 320°F and starts to burn toward 356°F, so a glaze brushed on at the start of 15 minutes in a 425°F oven scorches into a bitter crust before the sprouts are tender. Tossed in the hot pan off the heat, it bubbles, thickens on contact and clings in a glossy layer. For a shortcut, 4 tablespoons of bottled Thai sweet chili sauce with a squeeze of lime makes a quick sweet chili Brussels sprouts version.
Quick-Pickled Fresno Peppers
Quick-pickled Fresno peppers take 5 minutes of work: slice two red Fresno chiles into thin rings, pour over a warm brine of half a cup of white or cider vinegar, a quarter cup of water, a tablespoon of sugar and half a teaspoon of salt, and let them sit for at least 20 minutes. They turn the side bright, crunchy and sharp, and they bring a cleaner heat than the chili in the glaze. Fresnos look like small red jalapeños with a fruitier flavor and thinner walls, and the heat varies from pepper to pepper, so taste a ring before you scatter them.
One common belief is worth correcting: most of a chile's heat is not in the seeds. Capsaicin is made in the pale ribs inside the pepper, the placenta the seeds hang from; the seeds are hot only because they touch it. To tame the rings, trim out that white tissue; leaving the seeds in mostly changes the look. Refrigerator pickles like these are not heat-processed, so they must stay in the fridge. A university food preservation bulletin on refrigerator pickles calls for vinegar of 5% acidity, storage at 40°F or colder, and says quality holds for up to 2 weeks. The leftover rings are good on tacos, eggs and burgers, and in our watermelon Fresno margarita.
Spicy Brussels Sprouts in the Oven, on a Sheet Pan or in the Air Fryer
Spicy Brussels sprouts work three ways: a skillet sear finished in a 425°F oven gives the deepest browned faces, a sheet pan at 425°F handles a bigger holiday batch with no stovetop time, and an air fryer at 400°F gives the crispiest outer leaves for a small batch. The glaze and pickled peppers are the same for all three; only the cooking changes.
| Method | Heat | Time | Batch size | Result | Best for |
|---|---|---|---|---|---|
| Skillet sear, then oven | Medium-high burner, then 425°F | 4-6 min sear + 10-12 min oven | Up to about 2 lb in a 12-inch pan | Deepest, evenly browned cut faces | This recipe; serving with a steak |
| Sheet pan only | 425°F, cut-side down | 20-25 min | 2-3 lb on a large rimmed pan | Good browning, less even | Thanksgiving and big batches |
| Air fryer | 400°F, shake halfway | 12-15 min | About 1 lb at a time | Crispiest loose leaves, smaller faces browned | Two servings on a weeknight |
| Boiled or steamed | 212°F water or steam | 6-8 min | Any | Soft, pale, no browning | Not for this dish |
Whichever you pick, the glaze goes on at the end and the pickled peppers and cilantro go on at the table.
Serving, Making Ahead and Reheating
Serve spicy Brussels sprouts as soon as they are glazed, with a steak, roast chicken or pork, or on a Thanksgiving table where their sharp, sweet heat stands out against rich, creamy sides. For the full Hell's Kitchen plate, pair them with the bone-in ribeye; for another glazed side with a gentler profile, try the honey-glazed carrots, or for a green side done in the pan, Gordon Ramsay's asparagus.
For a holiday, do the work ahead and the cooking at the last minute. The pickled Fresnos keep in the fridge for up to 2 weeks, the glaze keeps for a week in a covered jar, and the sprouts can be trimmed and halved a day ahead and stored dry in a container lined with paper towel. Roast them just before dinner; cooked and reheated sprouts lose their crisp edges. Refrigerate leftovers within 2 hours, keep them 3 to 4 days and reheat to 165°F, per the USDA's leftovers guidance, ideally in a hot skillet or a 425°F oven so the edges crisp up again. Get the pan hot, keep the sprouts dry and glaze them last, and spicy Brussels sprouts come out caramelized every time.
Spicy Brussels Sprouts with Chili Glaze and Pickled Fresnos
Ingredients
Pickled Fresnos
- 2 red Fresno chiles, sliced into thin rings
- 1/2 cup white or apple cider vinegar (5% acidity)
- 1/4 cup water
- 1 tbsp sugar
- 1/2 tsp kosher salt
Sprouts
- 1 1/2 lb Brussels sprouts, trimmed and halved lengthwise, loose leaves kept
- 3 tbsp grapeseed or other neutral oil, divided
- 3/4 tsp kosher salt
Chili glaze
- 3 tbsp honey
- 1 1/2 tbsp chili garlic sauce or sambal oelek
- 1 tbsp rice vinegar
- 2 tsp soy sauce or tamari
- 1 tbsp fresh lime juice
To finish
- 1/4 cup micro cilantro or small cilantro leaves
Instructions
- Make the pickled Fresnos: warm the vinegar, water, sugar and salt in a small saucepan, stirring until dissolved. Put the Fresno rings in a small jar, pour the warm brine over them and set aside for at least 20 minutes (or refrigerate up to 2 weeks).
- Heat the oven to 425°F. Pat the halved sprouts and loose leaves completely dry, then toss them with 2 tablespoons of the oil and the salt.
- Heat a 12-inch oven-safe skillet over medium-high heat for 2 minutes, add the remaining 1 tablespoon oil, and lay the sprouts in a single layer, cut side down, with the loose leaves around them. Cook without stirring for 4 to 6 minutes, until the cut faces are deep golden brown.
- Move the skillet to the oven and roast for 10 to 12 minutes, until a paring knife slides into the thickest sprouts easily and the loose leaves are crisp.
- While the sprouts roast, simmer the honey, chili garlic sauce, rice vinegar and soy sauce in a small saucepan for 1 to 2 minutes, until slightly syrupy. Take it off the heat and stir in the lime juice. Taste and adjust the heat or sweetness.
- Take the skillet out of the oven (the handle is hot), pour the glaze over the sprouts and toss until glossy and coated. Transfer to a serving bowl, scatter over the drained pickled Fresno rings and the micro cilantro, and serve right away.
Notes
Spicy Brussels Sprouts FAQs
The questions that come up most: how to make Brussels sprouts spicy, how to take the bitterness out, whether to cut them in half, how long to roast them at 425°F, whether they work in an air fryer, how hot Fresno peppers are, and whether you can make them ahead.
How do you make Brussels sprouts spicy?
Toss them after roasting in a glaze of honey, chili garlic sauce or sambal oelek, rice vinegar, soy sauce and lime, then top with pickled Fresno or jalapeño rings. Red pepper flakes on the sprouts before roasting add a drier heat; the glaze gives a sweet heat that clings.
How do you get the bitterness out of Brussels sprouts?
Roast or sear them instead of boiling, so the outside browns and the natural sugars caramelize, and finish them with something sweet, sour and salty, like this chili glaze. Most sprouts sold today were bred to be milder than older varieties, so roasting usually leaves very little bitterness.
Should you cut Brussels sprouts in half before roasting?
Yes. A halved sprout has a flat cut face that sits flat on the pan and browns deeply and evenly, and the dense core cooks through faster. Very small sprouts can stay whole; very large ones can be quartered.
How long do you roast Brussels sprouts at 425°F?
About 20 to 25 minutes on a sheet pan, cut-side down, until the faces are deep brown and a knife slides into the core easily. Seared cut-side down in a skillet first, they need only 10 to 12 minutes in a 425°F oven.
Can you make spicy Brussels sprouts in the air fryer?
Yes. Toss the halved sprouts in oil and salt and air fry at 400°F for 12 to 15 minutes, shaking the basket halfway, then toss them in the warm chili glaze in a bowl. Cook about a pound at a time so they crisp instead of steaming.
Are Fresno peppers hotter than jalapeños?
They are close. Fresnos look like small red jalapeños and sit in a similar heat range, with a fruitier flavor and thinner walls, and heat varies from pepper to pepper. Most of the heat is in the white ribs inside, not the seeds, so trim the ribs for milder rings.
Can you make spicy Brussels sprouts ahead of time?
Make the parts ahead and roast at the last minute. Pickled Fresnos keep up to 2 weeks in the fridge, the glaze about a week, and the sprouts can be trimmed and halved a day ahead. Roasted sprouts reheated later lose their crisp edges; reheat leftovers in a hot oven or skillet to 165°F.
