Assemble ingredients on baking sheet

Lay down the chicken, evenly spaced, on the prepared baking sheet. Leave space in between each piece of chicken to allow for even cooking and to allow the chicken skin to get crispy. Sprinkle mushrooms, turnip and broccoli in between the chicken and around the pan. Brush butter garlic sauce all over both sides of chicken and vegetables.

Sheet Pan Chicken Dinner

Frequently Asked Questions

Can I use chicken thighs instead of chicken breasts for this recipe?

Absolutely! Chicken thighs work perfectly and are even juicier. Just adjust the cooking time slightly; thighs take a bit longer.

What vegetables can I add to the sheet pan?

I add any of my favorite vegetables! Broccoli, bell peppers, zucchini, and carrots all roast well. Just make sure to cut them into similar sizes for even cooking.

How can I store leftovers from the sheet pan chicken dinner?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.

Can I make this recipe dairy-free?

Yes! Substitute the butter with olive oil or vegan butter. Just make sure your mayonnaise is dairy-free.

What can I serve with this dish to make it a complete meal?

This dish is filling on its own, but I serve it with a side salad or keto cauliflower rice.

Keto Sheet Pan Chicken Recipe

a plate with two chicken legs and baked vegetables on it with a baking tray nearby

Sheet pan dinners are an easy way to get dinner on the table for my family, especially on busy days. Since everything is made in one pan, cleanup is quick. I line the baking pan with foil before starting, and the whole thing goes in the dishwasher when I’m done. I love this meal when I need something healthy and fast. This roasted chicken and vegetables combo is delicious, simple, and full of flavor. I make this as part of my meal prep. It makes great weekday work lunches. The garlic butter sauce makes this so much better than bland baked chicken and vegetables. You’ll have perfectly juicy chicken and crispy vegetables prepped and cooked in less than an hour. Just spread the chicken and vegetables in a single layer so everything cooks evenly.

Mix up your sheet pan dinner with different vegetables every time. This recipe is perfect for picky eaters since you can add any preferred vegetables. This low carb meal is a staple for weeknight dinners at our house. I squeeze a little lemon over it to finish.

How To Tell if Chicken is Done

To know your chicken legs are done, check the temperature by inserting a meat thermometer into the chicken legs, alongside the bone. The internal temperature needs to be 165 degrees. Don’t just check the color of the chicken; the color varies and isn’t accurate for doneness. The chicken stays juicy at this temperature.

Garlic Butter Sauce

The garlic butter marinade is high in fats (thanks to the butter and mayonnaise) and the chicken is high in protein, so this dish is very satisfying and keeps you full. Since all of the ingredients are keto-friendly, you can have a generous serving and stay within your macros.

For the garlic butter sauce, I use avocado mayo to add moisture. It keeps the chicken juicy while adding flavor. If you don’t have avocado mayo, regular mayo works. Add your favorite herbs to the sauce. I use parsley, but rosemary, thyme, or oregano pair well too. If you have time, marinate the chicken for up to 12 hours in the garlic butter mixture before baking, or just bake it right away. Marinating longer lets those flavors sink in.

If you don’t want to use mayonnaise or butter, substitute olive oil. Olive oil keeps the chicken juicy.

Roasted Vegetables on the Sheet Pan

A typical sheet pan chicken dinner includes potatoes. But potatoes are high in carbs, so I use turnips instead. Turnips are a great low carb substitute that looks and tastes like roasted potatoes when baked. You can also use radishes: they taste exactly like potatoes and have almost zero carbs. I add mushrooms and broccoli, but you can use any vegetables. I recommend asparagus, red onion, bell pepper, cauliflower, brussels sprouts, or green beans. You can make the sheet pan chicken dish as colorful as you want. Some people add sweet potato but that’s higher in carbs, so I skip it.

Benefits of Cooking in One Pan

Sheet pan dinners are quick and easy. The prep is simple: just add your ingredients to a sheet pan and brush them with sauce. You don’t need a lot of pots, pans, and utensils, so cleanup is fast. Even if you’re not confident in the kitchen, this recipe is easy. You just put everything on one baking tray and let the oven do the work.

Cuts of Chicken

For this recipe, I’m using chicken legs but you can substitute chicken thighs, chicken breast, or chicken tenders. The key is to choose cuts of chicken and vegetables that need about the same cooking time. Chicken breast takes less time to cook, so your vegetables will be less crispy. If you use bone-in cuts like thighs, they take longer to cook, so cut vegetables into bigger pieces or use vegetables that need longer cooking. For this sheet pan recipe, I don’t recommend a whole chicken. It takes too long to roast and the vegetables lose flavor by the time the chicken is done.

Storage

If you have leftovers, store the baked chicken legs and roasted vegetables in the refrigerator for up to 3 to 5 days. Both reheat well. To reheat, use the oven or microwave. You can freeze them, but they’re so quick to make, I just refrigerate them or eat them fresh.

    Added a squeeze of lemon right before it went in, mostly out of habit, and it cut through the richness of the garlic butter in a way I wasn't expecting. The mushrooms soaked it up and came out almost meaty-caramelized.

      Yeah lemon right before makes sense. The garlic butter is rich enough that the acid cuts it before it even roasts in. Never tried it that way but I'm doing it next time.

    I doubled this for Sunday meal prep and the garlic butter kept the chicken so juicy that the Wednesday leftovers were actually better than day one. One thing I've figured out: pack the mushrooms separately if you're prepping ahead, they go too soft otherwise and you lose that texture completely.

    1. Annie Lampella
      Annie Lampella Mar 2, 2026

      The mushroom call is right. They collapse fast once they're packed in with everything. I pull mine out separately too if I know it's going more than a day.

    i made this tonight and loved it! the sauce was so good that i wanted more of it. i made this for myself and just served it with a side of couscous for my boyfriend who’s not low carb. he loves it as well!

      The sauce is easy to double. I usually drizzle extra over everything the last 5 minutes of cooking so it caramelizes a bit.

    The recipe which is great! Made it with mushrooms broccoli and yellow peppers. But I believe you had a typo there should be half a teaspoon of salt not two teaspoons of salt.

    1. Annie Lampella
      Annie Lampella Feb 18, 2022

      Two teaspoons is right. The sauce coats the whole pan of chicken and vegetables so it needs more than it sounds like. And mushrooms on a sheet pan get so good when they roast.

    Used sliced zucchini and crookneck squash and radishes. It's what I had and my husband loved it! That is a big thumbs up because he is picky.

      Radishes on a sheet pan are underrated. They get so mellow when they roast. Glad the picky one approved!
