Recipe ingredients
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. We also use it in our sugar free salad dressing recipe.
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.
Garlic: 3 cloves of fresh garlic, finely minced are needed for this recipe.
Chicken Thighs: I'm using bone-in thighs with the skin on. You can use other cuts, including boneless thighs, legs, or breasts, but keep in mind that the cooking time will be different.
Brussel Sprouts: Trimmed and cut in half. See my tips below if you need to know more about how to trim brussels 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.

Step by step instructions
- Preheat the oven to 425°F/220°C and mix the marinade. In a 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 completely coated.
- Let the chicken marinate in the refrigerator for at least 20 minutes.
- Place the brussels 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 thighs into the vegetables.
- Bake as directed in the recipe card below, cooking until the chicken has reached an internal temperature of 165°F/74°C. Then turn the oven to broil and broil for 3-5 minutes, or until the chicken is browned. Serve immediately.

A simple green salad is always a good, healthy side dish to serve. For dessert, we recommend Keto Lemon Cake.
Expert tips
Marinate longer. For more flavor we recommend marinating for at least 6 hours.
Broil baby broil. I enjoy chicken thighs with crispy skin, so I use the broiler at the end. Be sure to watch carefully so that it doesn't burn.
Lemon zest. If you love lemon flavor, chop up the zest of a lemon and add to your marinade. We use lots of fresh lemon in our keto lemon bars.
FAQs
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 and soaking up the marinade. If your sprouts are very large you can cut them in quarters.
We suggest thawing the chicken before making this recipe. Frozen chicken will not absorb the marinade, and will take much longer to cook.
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, 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.
This meal includes high protein chicken and high fiber vegetables to create a low-carb and healthy meal. This recipe can definitely be a healthy option that fits into your overall diet.
Storage instructions
Fridge: Store any leftovers in an airtight container in the fridge for up to 4 days.
Freezer: You can keep in the freezer for up to 3 months. We recommend freezing in perfect portion sizes for a quick and easy meal when you don't feel like cooking.
Reheat: You can use the microwave, stove or oven until just warmed through. If using the stove, we suggest adding a little liquid (broth or water) to the pot and warming on low heat.
We like to put leftovers in containers and take them to lunch the next day. This is a great meal prep recipe.

Notes
- I prefer bone-in skin-on chicken for this recipe as it creates a really juicy and flavorful chicken. If you use a different cut of chicken, you may need to adjust the cook time accordingly.
- For extra crispy skin, broil the chicken for 3-5 minutes at the end of the baking time.
- If you do not like red onion, a yellow onion or sweet onion works just as well.
- If you love a more intense lemon flavor, add the chopped up zest of one lemon to your marinade.

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.

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.

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!
