If you’re looking for some ultra-simple inspiration alongside this, I have a whole list of 5-ingredient meals you might love.
For the Marinade and Glaze
This group is crucial because the marinade doesn’t just flavor the meat; the leftovers transform into that magical glaze!
- Balsamic vinegar: You need 1/2 cup.
- Extra-virgin olive oil: We’re using 4 tablespoons total—remember to divide it!
- Maple syrup: 2 tablespoons bring just the right touch of sweetness.
- Garlic: 3 cloves, minced finely.
- Kosher salt and freshly ground black pepper: 1/2 teaspoon of salt and 1/4 teaspoon of pepper, but taste and adjust later!
For the Chicken and Vegetables
This is where the magic happens on the actual sheet pan. Don’t skip the prep work on the veggies!
- Chicken thighs: Six lovely thighs are perfect for 6 servings.
- Brussels sprouts: About 1 pound, just make sure you trim the ends and slice them right in half.
- Red onion: One large onion, sliced into hearty wedges so it roasts nicely instead of burning.
Step-by-Step Instructions for Perfect Sheet Pan Balsamic Chicken and Brussels Sprouts
Okay, getting this done efficiently is all about timing your prep layers! We’re going to move fast but deliberately so everything hits perfection when it comes out of the oven. Remember, this is an ultimate dinner guide starter because it teaches you to work with your heat zones.
Preparing the Marinade and Marinating the Chicken
First things first, grab that medium bowl! Whisk together your balsamic vinegar, 2 tablespoons of that olive oil, the maple syrup, minced garlic, salt, and pepper until it’s all happy together. Now, take your chicken thighs and put them in a big bowl or even a sturdy plastic bag—my favorite for cleanup! Pour that marinade right over the chicken. You absolutely need to chill this for at least 1 hour, but if you can swing 2 hours in the fridge, the flavor payoff is huge!
Roasting the Vegetables and Chicken on the Sheet Pan
Time to wake up that oven; preheat it to a hot 425°F (220°C). While the oven’s warming up, toss your halved Brussels sprouts and your onion wedges right onto your big sheet pan. Drizzle on the *remaining* 2 tablespoons of olive oil and add a little extra salt and pepper just for the veggies. Use your hands to massage it all together right on the pan. Next, pull the chicken out, let any extra marinade drip off, and nestle the thighs in between all those vegetables.
Creating and Applying the Balsamic Glaze
This step is super important while the main pan is inside! Pour all that leftover marinade you didn’t use on the chicken into a small saucepan. Simmer that on medium-low heat for about 8 to 10 minutes. You want it to reduce and thicken nicely—seriously, reduce it until it coats the back of a spoon. When the chicken has been baking for a bit, pull the pan out and brush that reduced glaze right over the chicken!
Pop it back in. You’re going to repeat that brushing process one more time before you check it for doneness. Just make sure that chicken hits an internal temperature of 165°F (74°C) measured with an instant-read thermometer—that’s how you know it’s safe and perfectly cooked. (Pro tip: the glaze gets wonderfully thick and sticky as it cools down, so don’t worry if it looks a little thin the second time you put it on. If you prefer a thicker coating, you can try this amazing roasted balsamic chicken method for reference on glaze thickness).
Tips for Success with Your Sheet Pan Balsamic Chicken and Brussels Sprouts
Achieving that perfect texture—crispy sprouts kissing the edges and chicken that’s unbelievably juicy inside—is all about respecting the space on your pan. Seriously, don’t try to cram everything together! Overcrowding creates steam instead of those gorgeous roasted edges we’re aiming for. If you have to, just grab a second sheet pan for your veggies. That’s what I do when I’m making a bigger batch!
Another thing I learned the hard way is placement. Put the Brussels sprouts and onions towards the edges where the heat is most intense. The chicken goes in the middle. This is just one of those simple rules that makes any dinner idea foolproof. Always rely on that instant-read thermometer, too. Safety first, but hitting that 165°F mark means you haven’t dried out your gorgeous thighs!
Ingredient Substitutions for Sheet Pan Balsamic Chicken and Brussels Sprouts
I know everyone doesn’t keep chicken thighs stocked, and that’s totally fine! If you need to switch things up in this balsamic chicken recipe, you certainly can. If you grab chicken breasts instead, just watch the clock closely. They cook faster, so check them around 25 minutes in, since they definitely dry out quicker than thighs. You don’t want to end up with sad, rubbery meat!
Now, about the maple syrup. If you are strictly tracking carbs, you might want to swap that out. I usually reach for a teaspoon of monk fruit sweetener mixed into the marinade instead—it keeps that necessary sticky sweetness without the sugar impact. Also, if Brussels sprouts are giving you trouble, broccoli florets or even chopped sweet potatoes work great here, though potatoes will need a couple of extra minutes to soften properly.

Storing and Reheating Your Sheet Pan Balsamic Chicken and Brussels Sprouts
One of the absolute best things about using a sheet pan for dinner is that you almost always have leftovers, which is a win for the next day’s lunch! This Sheet Pan Balsamic Chicken and Brussels Sprouts actually tastes fantastic the next day because the flavors really marry together overnight.
When you’re done eating, let everything cool down completely, then scoop it into an airtight container. Because the chicken is so flavorful, honestly, it lasts great in the fridge for three to four days. I usually aim to eat it within three if I can, just to keep things at their peak freshness.
Now, reheating—this is where you protect the texture! I know it’s tempting to zap it in the microwave, but trust me, that steams the Brussels sprouts, making them soft when you wanted them crispy. If you’re having just a plate or two, pop them onto a clean sheet pan and reheat them at about 350°F (175°C) for about 10 minutes. If you own an air fryer, that thing is magic for leftovers; it crisps everything right back up!
If you’re planning ahead and want to make this ahead of time, this meal is great for meal prepping. If you need more ideas for quick post-work meals, you have to check out my 20-minute dinner roundup—but honestly, this balsamic chicken is usually faster if you marinate it beforehand!
Frequently Asked Questions About Sheet Pan Dinners
It’s funny how even the simplest cooking methods bring up the most questions! I get emails all the time asking for the nitty-gritty details on time management and ingredient swaps when it comes to these simple sheet pan dinners. Don’t worry—I’ve got you covered on all those little things that make the difference between an ‘okay’ meal and a ‘wow, I can’t believe I made that’ meal. I put together these common questions to help you nail every batch.
Can I use chicken breasts instead of thighs in this sheet pan dinners recipe?
Absolutely, you can substitute! Chicken thighs are my go-to here because they stay way more forgivingly moist while they cook that full 30 to 40 minutes it takes to perfectly roast the sprouts. If you use boneless, skinless chicken breasts, they won’t take as long! You’ll want to start checking their internal temperature around the 20-minute mark. We are still aiming for that safe 165°F, but breasts dry out fast if you leave them in too long. Maybe even place the breasts right on the edge of the pan for the last five minutes to make sure they finish right when the veggies look tender.
How do I prevent the Brussels sprouts from burning while waiting for the chicken to cook?
This is key to getting those wonderfully roasted brussels sprouts! If you are worried about them burning before your thighs hit that safe temperature, move them around! About halfway through the cook time, give the sprouts and onions a little stir or flip them over. This exposes fresh surfaces to the heat and keeps them from scorching on the bottom. Also, make sure they are cut in half—those cut sides caramelize beautifully, which protects the inner leaves from turning crispy black too fast!
Is the balsamic glaze keto-friendly in this balsamic chicken recipe?
That’s a smart question, especially since this is a keto-focused site! The truth is, traditional maple syrup has sugar. So, while the amount we use is relatively small for the flavor impact, if you are strictly keto, you’ll want to swap it out. I suggest skipping the 2 tablespoons of maple syrup and instead using 1 teaspoon of a keto-friendly liquid sweetener, like liquid sucralose or stevia, straight into the marinade reduction. That way, you get all the sticky, tangy power of the glaze without spiking your macros.
