Sheet Pan Chicken and Veggies

I make this at least once a week. Sometimes twice. It started as a lazy weeknight fallback, but after I figured out that 475°F is the temperature that actually works, it became the dinner my family requests. At 400 degrees, the broccoli steams. At 475, you get those dark, crispy tips that make the whole pan worth it.

If you like one-pan cooking, I have a whole rotation: sheet pan fajitas, cilantro lime chicken, and Italian keto chicken and rice. But this one is the simplest of the bunch because there is no marinade, no special sauce. Just olive oil, herbs, and a hot oven.

I use boneless, skinless chicken thighs for this. They handle high heat better than breast, and they stay juicy even if you go a minute or two over. Breast works too (I cover timing notes in the FAQs), but thighs are more forgiving and that matters on a busy night.

The vegetable mix is flexible. I default to broccoli, red bell pepper, onion, and tomato because they all roast evenly at the same cut size. But I have swapped in zucchini, green beans, cauliflower, and radishes depending on what needs to get used up. The key is cutting everything to roughly the same size so nothing burns while something else stays raw.

One thing I learned the hard way: do not overcrowd the pan. If you pile everything on, the vegetables release steam and you get soft, pale broccoli instead of charred edges. I use a full-size 18×26 sheet pan and spread everything in a single layer. If I am cooking for more than four people, I grab a second pan.

The seasoning is simple but it works. Oregano, basil, garlic powder, paprika, salt, and pepper. That paprika adds more than you would think. It is not a background flavor; it rounds out the herbs and gives the chicken a warmth that plain Italian seasoning misses.

If you want a change of pace with chicken, try my chicken stir fry for something saucy, or sheet pan fajitas when you want a Tex-Mex twist on the same one-pan method.

The whole keto dinner clocks in at about 5g net carbs per serving, depending on your vegetable mix. Fifteen minutes in the oven, one pan to wash. That is the kind of weeknight cooking I can keep up with.

1. Cut the chicken and vegetables into bite-sized pieces. Keep the cuts roughly the same size so everything finishes at the same time. I aim for 1-inch chunks on the chicken and similar on the broccoli and peppers.
2. Add everything to a large bowl. Toss with olive oil, oregano, basil, garlic powder, paprika, salt, and pepper until evenly coated.
3. Spread onto a sheet pan in a single layer with space between the pieces. If it looks crowded, use two pans. Crowding traps steam and kills the char.
4. Bake at 475°F for 15 minutes. Check the chicken with an instant-read thermometer; you want 165°F internal. The vegetables should be fork-tender with some browning on the edges.

Key ingredients

The best part of this low-carb roasted chicken is how flexible it is. Swap vegetables or seasonings based on what you have.

• Chicken thighs – My go-to for sheet pan cooking. They handle 475°F without drying out. Chicken breast works but cooks faster, so check it at 12 minutes. Drumsticks need different timing (30-35 minutes at 450°F).
• Vegetables – I used broccoli, onion, red bell pepper, and tomato. Cauliflower, zucchini, green beans, yellow squash, and radishes all work. Denser vegetables like cauliflower need smaller cuts. Try swapping broccoli for the same florets I use in my keto beef and broccoli.
• Olive oil – Coats everything for flavor and helps the vegetables crisp as they roast. Avocado oil or melted butter both work here.
• Seasoning – Oregano, basil, garlic powder, paprika, salt, and pepper. I use dried herbs but fresh works too. The paprika is not optional; it ties the blend together. If you love bold spice, try my blackened chicken seasoning approach.
