Honey Mustard Chicken Brussels

My kitchen was chaos that Thursday evening—I'd promised dinner for friends but had exactly thirty minutes and a sheet pan to work with. I remembered reading somewhere that honey mustard could transform even the plainest chicken, so I grabbed what I had: thighs instead of breasts, Brussels sprouts that needed using, and a red onion sitting on the counter. One pan, one oven, one glorious accident that turned into something I make constantly now.

I've made this for my sister's book club three times now, and I watch people reach for third helpings when they thought they didn't even like Brussels sprouts. That moment when someone realizes the vegetable on their plate is actually delicious, not just obligation—that's why I keep making this.

Ingredients

• Boneless, skinless chicken thighs (4, about 600 g): Thighs stay juicy where breasts dry out, and they forgive imperfect timing, which I appreciate on weeknights.
• Brussels sprouts (500 g, trimmed and halved): The flat sides caramelize against the pan if you don't move them too much—they get almost nutty and crispy at the edges.
• Red onion (1 medium, cut into wedges): These sweeten as they roast and add color that makes the whole plate look like you tried.
• Dijon mustard (3 tablespoons): Use the classic version, not the fancy stone-ground, because you need the smooth tang to coat everything evenly.
• Honey (2 tablespoons): This isn't garnish—it balances the mustard's sharp edge and browns beautifully in the oven heat.
• Whole grain mustard (1 tablespoon): The little seeds add texture and a hint of texture to the glaze that makes people pause and ask what that is.
• Garlic (2 cloves, minced): Raw garlic in the glaze stays sharp and alive rather than mellowing out—don't skip the mincing.
• Apple cider vinegar (1 tablespoon): This is the secret ingredient that keeps the glaze from turning one-note sweet.
• Smoked paprika (1/4 teaspoon): Just a whisper of smoke that makes people think you know more about cooking than you actually do.
• Olive oil (3 tablespoons total): Cheap oil here is fine since it's getting hot anyway, so save your good stuff for salads.
• Salt and black pepper: Season separately—some on the vegetables, some on the chicken, so flavors aren't competing for the same spots.

Instructions

Heat your oven and prep your pan:

Get the oven to 220°C (425°F)—this high heat is what makes the Brussels sprouts crispy instead of just soft. Line your sheet pan with parchment paper or a light grease so nothing sticks and cleanup doesn't become your evening project.

Build the glaze:

Whisk together Dijon mustard, honey, whole grain mustard, minced garlic, apple cider vinegar, and smoked paprika in a small bowl. You'll know it's right when it smells tangy and sweet at the same time and looks thick enough to coat a spoon.

Season and glaze the chicken:

Pat the chicken thighs dry with paper towels so they brown instead of steam. Toss them with 1 tablespoon olive oil, salt, and pepper, then add half the glaze and toss again until every piece is coated.

Prepare the vegetables:

On your sheet pan, toss Brussels sprouts and red onion with 2 tablespoons olive oil, salt, and pepper, then spread them into a single layer. Leave space in the middle and around the edges for the chicken so everything gets air and heat.

Arrange everything for roasting:

Nestle the glazed chicken thighs among the vegetables, skin side up if there's any skin, or just arranged so the glaze is visible. The vegetables should surround the chicken so they catch the drippings.

Roast until golden:

Put the whole pan in the oven for 25 to 30 minutes—you're looking for chicken that reads 74°C (165°F) at the thickest part and vegetables that are tender with crispy, caramelized edges. Halfway through, you can shake the pan to turn the vegetables if you're feeling attentive, but honestly it's not necessary.

Add the final glaze and finish:

In the last 5 minutes of cooking, brush the remaining glaze over the chicken so it gets sticky and glossy. This is the step that makes it look restaurant-quality.

Rest and serve:

Let everything sit on the counter for 2 to 3 minutes so the chicken doesn't lose all its juices the second you cut into it. Serve while it's still hot and the glaze is still shiny.

I learned the real point of this recipe last month when my neighbor came over, ate three thighs, and asked if I could teach her to make it. We stood in my kitchen for twenty minutes talking about vegetables and weeknight sanity instead of cooking blogs and perfection, and I realized that's exactly what this dinner is supposed to be about.

Why Chicken Thighs Win

Chicken breasts are lean and noble and will cook faster, but thighs are forgiving—they stay moist even if your oven runs hot or you forget about them for an extra five minutes. The darker meat also takes on flavors better, so the glaze actually penetrates instead of just sitting on the surface. I've switched to thighs for almost everything now, and I don't think I'll go back.

The Magic of Sheet Pan Roasting

There's something almost meditative about dumping everything on one pan and letting the oven handle it. You're not stirring constantly, you're not timing multiple components, and somehow things brown and caramelize better than when you baby them on the stovetop. The heat circulates, the vegetables catch the chicken drippings, and everything becomes greater than the sum of its parts.

What To Serve Alongside

This doesn't need much because the sheet pan already has vegetables and protein, but I often add something simple for balance. A crisp salad with lemon vinaigrette cuts through the richness of the glaze, or if I'm feeling heavier, crusty bread is perfect for soaking up the pan drippings. A chilled Chardonnay or light Pinot Noir pairs beautifully if you want to drink something while you're pretending you planned this whole dinner.

• Serve with a simple arugula salad tossed with lemon juice and olive oil for brightness.
• Crusty bread works perfectly for capturing every drop of glaze from the pan.
• A side of roasted potatoes or cauliflower rice bulks it up if you need more volume.

This recipe became my answer to the question that hits around 5 PM on weeknights: what do I actually feel like cooking? The answer is always this, because it's simple and it tastes like you care, and honestly that's the whole point.
