INGREDIENTS IN CHICKEN AND BRUSSEL SPROUTS
Olive Oil: A marinade that starts with olive oil will make these chicken thighs juicy and help them to get crispy. Having oil in the marinade also means that we don't have to grease the baking pan.
Dijon Mustard: I love the flavor of fancy mustard with brussel sprouts. The two just go together.
Lemon Juice: Use juice that is freshly squeezed for the best flavor. Added to our chicken marinade, lemon juice adds flavor and helps to tenderize the meat.
Thyme: Thyme complements all sorts of poultry but especially chicken perfectly. Use fresh thyme if you have it, or substitute with dried thyme.
Salt: We will season the chicken well using a bit of salt.
Black Pepper: Always welcome, black pepper adds warmth and the perfect amount of flavor to our chicken.
Garlic: 3 cloves of fresh garlic, finely minced are needed for this recipe.
Chicken Thighs: I'm using bone-in chicken thighs with the skin on. You can use other cuts of chicken, including boneless thighs, legs, or breasts, but keep in mind that the cooking time will be different.
Brussel Sprouts: Use one pound of brussel sprouts for your sheet pan dinner. Trim them and cut them in half. See my tips below if you need to know more about how to trim brussel sprouts.
Red Onion: Sliced red onion adds lots of flavor and beautiful color to this recipe.
Lemon: Thin lemon slices also roast up beautifully, and complement the lemon in the marinade. You can eat roasted lemon slices! But even if you don't eat them, they look really nice on the plate.

HOW TO MAKE CHICKEN AND BRUSSEL SPROUTS
- Preheat the oven to 425°F/220°C and mix the marinade. In s small bowl, whisk together the olive oil, Dijon mustard, lemon juice, fresh thyme, salt, ground black pepper, and minced garlic until combined.
- Add the chicken thighs to a large bowl. Pour ⅔ of the olive oil mixture over the chicken thighs. Toss until the chicken is completely coated.
- Let the chicken marinate in the refrigerator for at least 20 minutes.
- Place the brussel sprouts, sliced red onion, and sliced lemon in a medium bowl. Toss with the remaining olive oil mixture until well coated.
- Pour the vegetables out onto a baking sheet. Once the chicken has finished marinating, nestle the chicken thighs into the vegetables.
- Bake as directed in the recipe card below, cooking until the chicken has reached an internal temperature of 160°F/74°C. Then turn the oven to broil and broil for 3-5 minutes, or until the chicken is browned. Serve immediately.

TIPS FOR MAKING SHEET PAN CHICKEN AND BRUSSEL SPROUTS
Broiling is optional. I enjoy chicken thighs with crispy skin, so I use the broiler to ensure that browning happens. Be sure to watch the chicken carefully while it's under the broiler so that it doesn't burn.
Use just 1 lemon. If you have a large lemon, use half of it to get the juice for the marinate and slice the other half to include with the vegetables. if your lemons are smaller, you might need to use two.
Use another cut of chicken. If you want to make chicken and brussel sprouts with another type of chicken, like chicken legs or breasts, feel free. Just monitor to ensure that you cook it long enough to get the chicken to the proper temperature.
For extra flavor try adding a pinch of crushed red pepper or chili powder to the marinade. You can make it as spicy as you like!
WHAT TO SERVE WITH CHICKEN AND BRUSSEL SPROUTS
Your favorite side dishes added to this recipe will make a complete and satisfying meal.
To keep things low carb, make keto side dishes like my Keto Cheddar Biscuits or Low Carb Stuffing.
Otherwise, add a potato side dish. Mashed Potatoes or Scalloped Potatoes will be perfect with chicken and brussel sprouts.
A simple green salad is always a good, healthy side dish to serve with chicken too. For dessert, we recommend rocky road ice cream.
HOW LONG TO MARINATE CHICKEN THIGHS
For this recipe, I suggest a marinating time of at least 20 minutes for the chicken thighs. This is enough time for the outer layers of the thighs to soak up the flavors of the marinade.
You can marinate the chicken for up to 24 hours if needed, making this a great make-ahead chicken meal. Any longer than 24 hours will cause the chicken to start changing texture from the acid in the marinade.
I suggest marinating somewhere between 20 minutes and 12 hours for the best results.
HOW TO TRIM BRUSSEL SPROUTS
When you buy brussel sprouts, you need to clean them up a bit to get them ready to cook.
Start by slicing off the end/stem part of each brussel sprout. The ends are usually dry and brown and won't be very tasty. Next, peel off any outer leaves that are tough, thick, or damaged.
For this recipe, cut each sprout in half so that you get lots of surface area exposed for browning. If your sprouts are very large you can cut them in quarters.
HOW TO STORE LEFTOVER CHICKEN AND BRUSSEL SPROUTS
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat using the microwave or oven until just warmed through.
We like to put leftovers in containers and take them to lunch the next day. This is a great meal prep recipe.

OTHER VEGGIES TO ADD TO THIS RECIPE
Keep this recipe low carb by adding other keto vegetables to the pan. Asparagus, mushrooms, green beans, or radishes are all excellent options.
If you want to add other vegetables to sheet pan chicken and brussel sprouts, reduce the amount of brussel sprouts so that you don't overfill the sheet pan. Too many veggies on the pan will cause them to steam rather than roast.
Or, just use two pans, and fill the second one with all of your extra vegetables. I can never get enough roasted vegetables, so I like this option. Rotate the trays in the oven as needed.
If you aren't a huge fan of brussel sprouts, you can leave them out of this recipe entirely, and replace them with another vegetable that you do like!
CAN I USE WHITE ONION?
I chose to use red onion in this sheet pan chicken dinner recipe because I love the color that it gives. A white or yellow onion will still be delicious though, so use whatever type of onion you have on hand.
IS CHICKEN AND BRUSSEL SPROUTS HEALTHY?
This meal includes high protein chicken and high fiber vegetables to create a low-carb and healthy meal. Sheet pan chicken and brussel sprouts can definitely be a healthy option that fits into your overall diet.
CAN I MAKE SHEET PAN CHICKEN AND BRUSSEL SPROUTS WITH FROZEN CHICKEN?
I suggest thawing the chicken before making this recipe. Frozen chicken will not absorb the marinade, and will take much longer to cook.

Our family has recently been working on a lower carb diet and this is the second time in a couple weeks that we are trying this recipe. We have added capers and I also used up some broccoli with the Brussel sprouts and red onion. Really yummy recipe! Thanks!

We made this last night. Didn't follow the instructions exactly but it still turned out AMAZING. I let the marinade sit 20 minutes vs. letting the chicken sit in the marinade; when I figured that out, I just went ahead and threw everything together in a big bowl except the lemon slices, and stirred it all until everything was coated with the marinade. I let that all sit while the oven warmed up, then spread out the veggies, layered the lemon slices on top, and then the chicken over all that. Baked as directed. Seriously spent the next 20 minutes trying to peel ALL the delicious caramelized bits off the aluminum foil. Served with a mash of roasted cauliflower and sweet potatoes I'd made earlier. Only thing I would change is to increase the brussels to 1.5-2 lbs.

Can you use chicken breast instead and what changes in cooking should I make
Four Score Living
Yes, you can use chicken breast. You may need to increase or reduce the baking time, depending on how thick they are.
