There’s something deeply comforting about the combination of sticky-sweet barbecue chicken and caramelized Brussels sprouts emerging from a single sheet pan. This recipe was born on a frantic Tuesday night when my refrigerator held little more than a pack of bone-in chicken thighs, a pint of Brussels sprouts, and a half-empty bottle of my favorite smoky-sweet BBQ sauce. What started as desperation dinner has since become the meal my family requests most often—yes, even over take-out pizza.

I love this dish because it tastes like you spent hours tending a grill, yet the oven does all the heavy lifting. The chicken skin renders to crackling perfection while the meat stays succulently juicy, and the sprouts soak up all those glorious chicken drippings, turning them into vegetable candy. It’s weeknight-simple, weekend-impressive, and potluck-hero material all rolled into one. Whether you’re feeding hungry teenagers, meal-prepping for the workweek, or hosting friends for game night, this recipe delivers big, bold flavor with minimal fuss.

Why This Recipe Works

One-Pan Wonder: Chicken and vegetables roast together, saving dishes and infusing the sprouts with smoky chicken flavor.
Crispy Skin Guaranteed: Starting skin-side down in a hot oven, then flipping and basting ensures lacquered, crackling skin every time.
Flavor Layering: A quick dry-brine, a mustard-garlic rub, and two rounds of BBQ sauce create deep, complex flavor without marinating overnight.
Flexible Timing: The recipe is forgiving—if you’re running late, let the chicken rest in its sticky glaze; if dinner’s early, keep it warm without drying out.
Freezer-Friendly: Double the batch and freeze half the thighs in the rub; thaw overnight for an almost-instant future meal.
Vegetable Candy: Halved Brussels sprouts roast cut-side down so they caramelize into sweet, tender morsels that convert even the skeptics.

Ingredients You'll Need

Great meals start with great ingredients, but that doesn’t mean you need to break the bank. Here’s what to look for—and what you can swap—so you can shop your pantry first.

Chicken Thighs

I strongly recommend bone-in, skin-on thighs. The bone conducts heat evenly so the meat stays juicy, while the skin acts as a self-basting blanket of flavor. If you only have boneless, reduce the initial roast time by 10 minutes and check for 175 °F internal temp. Organic, air-chilled chicken will give you the crispiest skin because it hasn’t been pumped with excess water.

BBQ Sauce

Use your favorite bottled sauce—sweet, smoky, spicy, Kansas City, Carolina, whatever makes you happy. I reach for a hickory-smoked, molasses-forward sauce for maximum stickiness. If you’re feeling ambitious, stir together 1 cup ketchup, ¼ cup apple-cider vinegar, 3 Tbsp brown sugar, 1 Tbsp Worcestershire, 1 tsp smoked paprika, and a pinch of cayenne; simmer 10 minutes.

Brussels Sprouts

Look for tight, bright-green sprouts on the smaller side—they’re sweeter and roast faster. If your grocery only has giant ones, quarter them instead of halving. Frozen Brussels will roast acceptably; thaw, pat very dry, and add 5 extra minutes.

Dijon Mustard

The mustard’s acidity tenderizes and its tang balances the sweet sauce. Whole-grain Dijon adds texture, but smooth is fine. No mustard? Sub 1 tsp vinegar + 1 tsp mayo.

Smoked Paprika

This is the secret to oven “barbecue” flavor. Sweet paprika works in a pinch, but add ¼ tsp chipotle powder for smoke. Hungarian paprika is warmer; Spanish is bolder—use what you have.

Dark Brown Sugar

Its molasses notes mimic deep grill caramelization. Light brown is fine; coconut sugar adds subtle toffee. In a pinch, 2 Tbsp honey + 1 Tbsp soy sauce creates a similar glaze.

How to Make Baked BBQ Chicken Thighs with Roasted Brussels

Dry-brine for crispy skin

Pat 6 chicken thighs very dry with paper towels. Mix 1 tsp kosher salt, ½ tsp black pepper, and ½ tsp smoked paprika. Rub all over, including under the skin where possible. Set on a wire rack over a rimmed baking sheet and refrigerate uncovered 1–24 hours. The circulating air dehydrates the skin, guaranteeing shatter-level crunch later.

Preheat & prep vegetables

Heat oven to 425 °F (220 °C). Trim 1½ lb Brussels sprouts, halve them, and toss with 2 Tbsp olive oil, ½ tsp salt, and ¼ tsp pepper. Arrange cut-side down on one half of a parchment-lined, rimmed sheet pan. Leave space between each sprout so they caramelize instead of steam.

Make the quick rub

In a small bowl combine 2 Tbsp Dijon mustard, 1 tsp garlic powder, 1 tsp dark brown sugar, ½ tsp smoked paprika, ¼ tsp cayenne, and 1 Tbsp olive oil. Slather the mixture over the chicken, again lifting the skin to season underneath. This paste adds flavor and helps the first layer of sauce adhere.

First roast—skin contact

Nestle the thighs skin-side down among the Brussels. Roast 20 minutes. Starting skin-down renders fat directly onto the pan surface, creating a self-basting environment and jump-starting crispiness.

Flip & glaze

Remove pan, flip thighs skin-side up. Brush with ⅓ cup BBQ sauce. Roast another 15 minutes. The sauce will begin to caramelize but not burn.

Final lacquer

Brush on remaining ⅓ cup sauce, increase heat to 450 °F, and roast 5–7 minutes more until skin is burnished and an instant-read thermometer registers 175 °F in the thickest part. Rest 5 minutes so juices redistribute and glaze sets.

Expert Tips

De-fat the pan juices

After resting, tilt the pan and spoon off excess schmaltz. The remaining sticky juices are liquid gold—drizzle over rice or mashed potatoes.

Check early

Thigh thickness varies; start checking temp at the 35-minute mark. Overcooking dries the edges and can bitter the sauce.

Overnight flavor bomb

Mix the mustard rub, coat the chicken, and refrigerate up to 24 hours. The salt penetrates deeply, seasoning to the bone.

Crisp-reset

If the skin ever gets soggy during hold time, pop thighs under a hot broiler 1–2 minutes to re-crisp.

Sheet-pan upgrade

Use a dark-colored sheet pan for deeper caramelization. If yours is thin, stack two pans to prevent hot spots.

Sauce switch-ups

Stir 1 tsp sriracha into the sauce for heat, or 2 tsp peach jam for fruity depth. Taste and tailor!

Variations to Try

Keto: Swap brown sugar for 1 Tbsp granular erythritol and use a no-sugar BBQ sauce.
Honey-Garlic: Replace BBQ sauce with ½ cup honey, 2 Tbsp soy sauce, 1 Tbsp rice vinegar, and 4 minced garlic cloves.
Asian-Inspired: Add 1 tsp sesame oil to the rub, glaze with teriyaki, and finish with sesame seeds and scallions.
Vegetable Medley: Substitute half the sprouts with baby carrots and cubed sweet potato; roast time stays the same.
Dutch-Oven: Brown thighs on the stovetop, add sauce and sprouts, cover and bake 35 minutes at 375 °F for braised texture.
Outdoor Grill: Grill thighs over indirect heat 30 minutes, brushing with sauce last 10 minutes; roast sprouts separately in a grill basket.

Storage Tips

Refrigerate: Cool completely, transfer to an airtight container, and refrigerate up to 4 days. For best texture, store chicken and sprouts separately.

Freeze: Wrap individual thighs tightly in foil, then place in a freezer bag; freeze up to 3 months. Thaw overnight in the fridge and reheat at 350 °F for 15 minutes. Brussels sprouts freeze adequately but will be softer; flash-freeze on a tray first to prevent clumping.

Meal-Prep: Cube leftover chicken and sprouts, toss with cooked quinoa, a handful of spinach, and extra BBQ sauce for instant lunches.

Leftover Magic: Shred chicken, layer on buns with coleslaw, and broil 2 minutes for quick BBQ sandwiches. Chop sprouts and fold into scrambled eggs with cheddar for smoky breakfast tacos.

Frequently Asked Questions

Yes—reduce initial roast to 15 minutes, flip, glaze, and cook 10–12 minutes more until 165 °F. They’ll be slightly less juicy but still delicious.

Choose smaller, fresh sprouts and roast until deeply browned. A drizzle of balsamic or a sprinkle of brown sugar during the last 5 minutes balances bitterness.

Absolutely—use two sheet pans placed on separate racks, switching positions halfway through. Do not crowd or the chicken will steam.

Place thighs directly on the parchment. The skin won’t be quite as crispy underneath, but flipping skin-side up for the final blast compensates.

Cover with foil and warm at 325 °F for 15 minutes, uncovering for the last 3 to re-crisp skin. Add a splash of broth or sauce to keep meat moist.

Yes, as long as your BBQ sauce is gluten-free (many are). Check labels for Worcestershire or soy sauce derivatives if you’re highly sensitive.
