Ingredients for baked chicken and brussel sprout
Just nine ingredients for restaurant-style crispy chicken and Brussels sprouts—no fancy prep needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Thighs 🍗 | 1 ½ lb | Bone-in, skin-on preferred |
| Brussels Sprouts 🥬 | 1 ½ lb | Trimmed, halved lengthwise |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For crispy edges |
| Garlic Cloves 🧄 | 4 cloves | Minced for seasoning |
| Dried Thyme 🌿 | 1 tbsp | Or 1 tbsp fresh thyme |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Brown Sugar 🍯 | 1 tbsp | For caramelized edges |
| Apple Cider Vinegar 🍎 | 1 tbsp | Brightens flavor |
| Balsamic Glaze 🍷 | 2 tbsp | For drizzling (optional) |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
The chicken thighs are the star here. Bone-in, skin-on gives the best flavor and texture, but boneless works too—just pat them dry first. I grab mine from Costco when I'm doing a big batch, but any grocery store has them. Look for thighs with good marbling—they stay juicier. Brussels sprouts? Trader Joe's always has the pre-trimmed ones, which saves time. If you're using whole sprouts, halve them lengthwise so they crisp up faster. The secret to crispy edges is high heat and tossing them halfway through—don't skip that step!
No bone-in chicken? Use boneless thighs and press them with your palm to even thickness. Short on thyme? Dried oregano at half the amount works in a pinch. The brown sugar might seem odd, but it's what gives those caramelized edges—coconut sugar works too. Apple cider vinegar adds brightness, but lemon juice at the same amount is a fine swap. For the balsamic glaze, I use Trader Joe's reduced balsamic—it's sweeter and cheaper than the fancy stuff. Fresh parsley is ideal for garnish, but dried parsley at one-third the amount gets the job done if you're in a hurry.
This dish reheats beautifully—just pop it in the oven at 375°F for 10 minutes. Keeps for 3-4 days in the fridge, though it's best fresh. For meal prep, portion the chicken and sprouts separately so they stay crispy. The leftovers taste even better the next day once everything melds. Store the balsamic glaze separately and drizzle fresh before serving. If you're making this ahead, roast the chicken and sprouts separately and toss together before serving to keep everything crisp.

- Thyme for Crunch: Between us, Brussels sprouts can be polarizing—but this method turns them into crispy, caramelized bites with that earthy garlic-thyme punch. The chicken? Juicy and golden, with a skin so tender it practically melts. Honestly, the combo makes even Brussels-haters ask for seconds.

Step-by-step instructions for crispy roasted chicken and Brussels sprouts
Here's how to get that perfect balance of crispy chicken skin and caramelized Brussels sprouts every time.
Prep the Chicken and Brussels Sprouts
Preheat your oven to 425°F—this high heat is key for crispy skin. Pat the 1.5 lb chicken thighs completely dry with paper towels, especially the skin. Any moisture will prevent proper browning. Season both sides generously with 1.5 tsp salt, 0.5 tsp ground black pepper, and 1 tbsp dried thyme, pressing the spices into the meat so they stick.
Halve the 1.5 lb Brussels sprouts lengthwise and trim any tough ends. Toss them in a large bowl with 0.25 cup extra-virgin olive oil, 1 tbsp brown sugar, 1 tbsp apple cider vinegar, and a pinch of salt. The sugar will help caramelize the edges while the vinegar brightens the flavor. Spread them on a separate baking sheet.
Roast the Chicken Until Golden
Place the seasoned chicken thighs skin-side down on a wire rack set over a baking sheet. This rack allows air to circulate underneath, ensuring crispy skin all over. Roast for 25 minutes, then flip the thighs skin-side up. Return to the oven for another 20-25 minutes until the skin is deep golden brown and crispy, and the internal temperature reaches 165°F.
Here's the thing—don't open the oven door during cooking. Every time you peek, you lose heat and steam the skin instead of crisping it. If you're worried, use an oven thermometer to confirm the temperature stays steady.
Caramelize the Brussels Sprouts
While the chicken roasts, toss the Brussels sprouts again to redistribute the oil and sugar mixture. Spread them out in a single layer on the baking sheet—this ensures even browning. Roast them alongside the chicken for 25-30 minutes, stirring halfway through, until the edges are deeply caramelized and crispy. You'll know they're done when the sprouts smell sweet and toasty, and the edges are almost blackened in spots.
If they're browning too quickly, tent the pan with foil to prevent burning. The goal is crispy, not burnt—so keep an eye on them during the last few minutes.
Finish and Serve
Once the chicken is done, transfer it to a cutting board and let it rest for 5 minutes. This resting time keeps the juices inside the meat instead of running out when you slice. While it rests, drizzle the Brussels sprouts with 2 tbsp balsamic glaze and toss gently to coat. The glaze adds a tangy contrast to the caramelized edges.
Slice the chicken thighs against the grain for tender, easy-to-chew pieces. Garnish everything with 0.25 cup chopped fresh parsley for a pop of color and freshness. Serve immediately—this dish tastes best while the chicken is still juicy and the Brussels sprouts are crispy.
Pro Tips For Making Baked Chicken And Brussel Sprout
- USE HIGH HEAT FIRST: Roast the Brussels sprouts at 450°F (230°C) for the first 10 minutes—this caramelizes their edges before the chicken goes in. I used to bake everything together at 375°F, and the sprouts ended up soggy. High heat early locks in that crisp-tender texture.
- TRIM THYME STEMS: Crush the dried thyme between your fingers before sprinkling it over the chicken—this releases the flavor oils. I learned this the hard way after measuring out whole stems and wondering why the dish tasted flat. A quick pinch goes a long way.
- SKIP THE CROWDED PAN: Space the chicken thighs at least 1 inch apart on the tray—otherwise, they’ll steam instead of brown. I used to jam them in tight, and the result was pale, rubbery meat. Give them room to crisp, even if it means two batches.
- ADD GARLIC LATE: Toss minced garlic with the Brussels sprouts after they’ve roasted for 15 minutes—this prevents it from burning into oblivion. I was skeptical until I tried it: the garlic gets nutty and aromatic instead of bitter. Just sprinkle it on like confetti.
Dietary considerations for this baked chicken and brussel sprout
Gluten-Free Adaptations
This recipe is naturally gluten-free, but I always double-check my ingredients to avoid cross-contamination. The brown sugar and apple cider vinegar used here are typically gluten-free, but always verify labels if you're highly sensitive.
For extra safety, I use certified gluten-free balsamic glaze—Annie's Homegrown makes a great one. The Brussels sprouts and chicken are gluten-free by nature, so no substitutions are needed there. 🌱
Dairy-Free Options
If you're avoiding dairy, this recipe stays perfectly safe since it doesn't contain any cheese or butter. The crispy edges come from the olive oil and brown sugar caramelization, not dairy.
For an extra flavor boost, I sometimes add 1 tsp smoked paprika to the chicken seasoning—it adds depth without any dairy. The balsamic glaze also works beautifully as a dairy-free finishing touch. ✨
Low-Carb Considerations
This dish is already low-carb friendly, with Brussels sprouts providing fiber and the chicken offering lean protein. The 1 tbsp brown sugar in the sprouts adds minimal carbs, but if you're strict about carb counting, you can reduce it to ½ tbsp or use erythritol instead.
The apple cider vinegar and balsamic glaze add flavor without significant carbs, making this a great option for keto or low-carb diets. 🥦
Allergen-Friendly Swaps
For nut allergies, this recipe is already safe, but I always check my extra-virgin olive oil label to ensure it's processed in a nut-free facility. If you're avoiding garlic, substitute the 4 minced cloves with 1 tsp garlic powder—it's less potent but still adds flavor.
For a soy-free version, make sure your balsamic glaze is soy-free (some brands contain soy-based additives). The fresh parsley garnish is also allergen-free, so no changes are needed there.
Vegetarian Adaptation
While this recipe features chicken, you can easily make a vegetarian version by swapping the thighs for extra-firm tofu or portobello mushrooms.
For tofu, press and marinate 1.5 lb firm tofu in a mix of 2 tbsp soy sauce, 1 tbsp olive oil, and 1 tsp smoked paprika for 15 minutes before roasting.
For mushrooms, slice 4 large portobellos and roast them with the Brussels sprouts for the same 25-30 minutes**. The caramelized edges will still shine! 🌿

Frequently asked questions
Can I use chicken breasts instead of thighs for this recipe?
Chicken breasts will work, but they're leaner and require extra care to stay juicy. Pat them bone-dry, pound to ½-inch thickness, and reduce oven time to 15-20 minutes total (skin-side down first). Add 1 tsp olive oil to the seasoning mix to help crisp the skin. The breasts will be less forgiving than thighs if overcooked.
What if my Brussels sprouts aren't crispy after roasting?
Overcrowding the pan or using wet sprouts are the usual culprits. Next time, spread them in a single layer and pat them dry before roasting. For extra crispiness, broil for 1-2 minutes at the end (watch closely!). If they're still soft, they likely need 5-10 more minutes at 425°F.
How can I make this meal ahead of time?
Roast the chicken and Brussels sprouts separately, then store them in airtight containers for up to 3 days. Reheat chicken at 375°F for 10 minutes and sprouts at 400°F for 5 minutes to restore crispiness. Keep the balsamic glaze separate and add it fresh before serving for maximum flavor.
What's the best way to slice the chicken for serving?
Slice against the grain at a 45-degree angle for tender, bite-sized pieces. For presentation, arrange the slices on a platter with the Brussels sprouts fanned around them. The crispy edges will look stunning! If you prefer larger portions, cut into 1-inch thick medallions instead.
Can I substitute frozen Brussels sprouts?
Yes, but thaw and dry them thoroughly first to prevent soggy results. Use the same roasting time, but check at 20 minutes since frozen sprouts may need less time. For extra crispiness, toss with ½ tsp cornstarch before roasting—it helps create that perfect texture.
