One pan and 15 minutes in the oven: sheet pan chicken and veggies with juicy thighs and crispy roasted edges, all at 475°F. 4.5g net carbs and 20.1g protein. Tossed in herbs and olive oil, with almost no cleanup.
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.
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 18x26 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 4.5g net carbs per serving with my standard vegetable mix. Fifteen minutes in the oven, one pan to wash. That is the kind of weeknight cooking I can keep up with.
Can I meal prep roasted chicken and vegetables?
I meal prep this almost every Sunday. Roast a double batch, let it cool, then portion into five containers. The chicken and broccoli hold up well for 4-5 days in the fridge. Bell peppers stay fine too, though they soften a bit by day four.
For freezing, the chicken freezes great for up to 3 months. Broccoli and peppers get mushy after thawing, so I only freeze the chicken portions and roast fresh vegetables when I reheat. If you want another keto meal prep option, my keto chicken casserole also portions well.
How to store leftover roasted chicken and veggies
I store leftovers in airtight glass containers in the fridge for up to 4 days. Reheat in the oven at 400°F for 8-10 minutes to get some of the crispness back. The microwave works in a pinch, but the vegetables lose their texture.
If you are freezing, store the chicken separate from the vegetables. The chicken reheats well from frozen (I thaw overnight in the fridge, then reheat in the oven). The vegetables do not survive the freezer as well, so I roast a fresh batch of whatever I have on hand.
Why cooking chicken and vegetables together works
The reason this works is that bite-sized chicken pieces and chopped vegetables cook at the same rate at 475°F. I cut my chicken into 1-inch cubes and keep the vegetable pieces similar in size. If your broccoli florets are huge, break them down. If your onion chunks are too thick, they will still be crunchy when the chicken is done.
The high heat sears the outside of the chicken while the vegetables caramelize. Everything finishes in 15 minutes. If you are cooking bone-in pieces, that is a different recipe entirely. For another one-pan chicken dinner with a different flavor profile, try my huli huli chicken.
Do I need to cover the pan when roasting?
No. I never cover this when it roasts. You want the moisture to escape so the vegetables char instead of steam. Covering the pan traps steam, and steamed broccoli is not what we are going for here. The whole point of 475°F is to get those dark, crispy edges on the broccoli and caramelized bits on the peppers. A lid or foil would undo all of that.
How to make roasted chicken and veggies on a sheet pan
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.
Add everything to a large bowl. Toss with olive oil, oregano, basil, garlic powder, paprika, salt, and pepper until evenly coated.
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.
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.
Place cubed chicken and diced vegetables in a large bowl. Add olive oil, salt, oregano, basil, garlic powder, black pepper, and paprika. Toss until coated.

Frequently Asked Questions
How do I stop my vegetables from getting soggy?
Two things I learned from making this dozens of times: do not overcrowd the pan, and make sure your vegetables are dry before tossing them in oil. I spread everything in a single layer with space between the pieces. If it looks tight, I grab a second pan. Crowding traps steam and that is what makes things soggy.
Can I use frozen vegetables?
I have tried it and I do not recommend it straight from the bag. Frozen vegetables release a lot of water as they thaw, and that water pools on the pan and prevents any browning. If frozen is all you have, thaw them first and pat dry with a towel before tossing with oil. The results are not as good as fresh, but they are passable.
Can I use bone-in, skin-on chicken thighs?
I have made this with bone-in thighs and it works, but the timing changes. I roast bone-in pieces at 450°F for 30-35 minutes, then broil for 2-3 minutes at the end to crisp the skin. The vegetables go in for the last 15 minutes so they do not burn. It is more hands-on than the boneless version but the crispy skin is worth it.
How do I know when the chicken is done?
I use an instant-read thermometer every time. You want 165°F internal temperature on the thickest piece. With boneless thighs cut into 1-inch cubes at 475°F, mine hits 165 right at the 15-minute mark. Chicken breast cubes usually get there by 12 minutes, so I start checking earlier.
What low-carb vegetables can replace potatoes in this recipe?
I have tested a bunch of swaps. Radishes are my favorite because they lose their bite when roasted and get soft like a small potato. Turnips work well too, cut into half-inch cubes. Cauliflower florets crisp up nicely at 475°F. Brussels sprouts (halved) are great if you want something heartier. I skip jicama for roasting; it stays too crunchy.
Can I make this recipe ahead of time?
I prep the chicken and vegetables the night before all the time. Toss everything with oil and seasonings, store in a sealed container in the fridge, and pour it onto the sheet pan when I am ready to cook. The seasoning actually soaks into the chicken overnight, so it comes out even more flavorful. I do not recommend roasting ahead and reheating for dinner; it is better fresh.
Can you cook chicken and veggies on the same sheet pan?
Yes, that is exactly how I make this recipe. I cut boneless chicken thighs into 1-inch pieces, keep the vegetables a similar size, and roast everything together at 475°F for 15 minutes. Same cut size means the chicken and vegetables finish at the same time. Check the thickest piece of chicken for 165°F internal before serving.
How long to cook sheet pan chicken and veggies in the oven?
Fifteen minutes at 475°F. That is all my version needs because the chicken is cut into 1-inch pieces and the vegetables match that size. I check the thickest piece with an instant-read thermometer and pull the pan at 165°F internal. Chicken breast cubes usually finish by 12 minutes, so I start checking earlier when I use breast.
20 grams of protein at 229 calories per serving. Recalculated twice because I was sure I messed up the portions. Made a full batch Sunday, split into four containers, and I’ve been looking forward to lunch every day this week, which is not something I normally say about meal prep. The 15 minutes at 475 still made me nervous (hovered by the oven the whole time) but everything came out with that slight char and the chicken stayed juicy. The broccoli by Wednesday might have been better than day one, like it had time to soak everything up. Going to double it next Sunday and see if it holds the full week.
Oregano at 475 and then garlic right behind it, kitchen smelled like a real dinner and I realized I’d crossed this off the list when I went keto. Wrong about that.
I’ve tried probably five or six sheet pan chicken recipes since I started keto in January. Most come out soggy, like the veggies steam instead of roast. This one is the first time I actually got color on the broccoli and some char on the peppers, and I’m pretty sure it’s just because 475 is way hotter than what I was doing before. Everything was done in 15 minutes and I kept checking the oven like that couldn’t be right. Oregano and basil, nothing fancy, but it works. Doesn’t taste like food I settled for. I’d have given it five stars but my tomatoes basically dissolved, so next time I’m throwing them in the last five minutes. Either way, I’m done hunting for a different sheet pan recipe.
Made this probably five times and I finally stopped pulling it early. The broccoli wants the full 475, trust it. Those charred edges are the whole reason I keep coming back.
I was convinced 15 minutes at 475 wasn’t going to be enough and I’d end up with raw chicken. Pulled it out and the edges of the broccoli were almost charred in the best way, chicken completely done. I owe this recipe an apology.
I barely cook, so I expected to mess this up somehow, but I just tossed everything in a bowl, spread it on the foil, and 15 minutes later had actual dinner. First time making anything keto and I surprised myself.
Added zucchini the second time because I had it going soft in the crisper, and at 475 those edges get this char I wasn’t expecting. So much better than it should be for something I just threw in. Now I use whatever’s about to turn and it always works. Bell pepper and broccoli from the original is still my favorite though.
Tried this with mushrooms and zucchini swapped in for the bell pepper and the mushrooms came out with this deep golden char at 475 that I wasn’t expecting. Tip: spread them out more than feels necessary or they’ll steam and go soft instead. I did bump up the seasoning with some smoked paprika because the base mix felt a little light for my taste, but that’s an easy fix and it’s been a weeknight staple since.
That mushroom char at 475 is something. They need twice the room you think, and even then I’d check them at 10 minutes. Smoked paprika is a good call, I’d go a full half teaspoon.
Fourth time in as many months. Basically making it by memory now. 15 minutes at 475 is right, broccoli actually chars instead of steaming itself to mush. Four stars because I keep forgetting to buy enough veggies. Recipe’s fine, I’m just bad at planning.
Was convinced 475 was going to destroy the chicken. Broccoli got those dark crispy tips and the chicken came out juicy at 15 minutes. Did not expect a sheet pan to humble me like this.
