Ingredient Checklist


Instructions Checklist
  • Position rack in lower third of oven; preheat to 450 degrees F. Place a large rimmed baking sheet in the oven to preheat.

  • Combine mustard, thyme, 1 tablespoon oil and 1/4 teaspoon each salt and pepper in a small bowl; spread the mixture evenly on chicken.

  • Toss sweet potatoes and onion in a bowl with the remaining 1 tablespoon oil and 1/4 teaspoon each salt and pepper. Carefully remove the baking sheet from the oven and spread the vegetables on it. Place the chicken on top of the vegetables.

  • Return the pan to the oven and roast, stirring the vegetables once halfway through, until the vegetables are tender and beginning to brown and an instant-read thermometer inserted into a chicken thigh registers 165 degrees F, 30 to 35 minutes.


Cut Down on Dishes: A rimmed baking sheet is great for everything from roasting to catching accidental drips and spills. For effortless cleanup and to keep your baking sheets in tip-top shape, line them with a layer of foil before each use.

I followed the directions exactly and thought the flavor of the chicken was too strong. I did really enjoy the sweet potatoes and onions. However my daughter and my husband didn't like the dish at all. Read More

Surprisingly flavorful I was really afraid the chicken wasn't going to be that flavorful but it was really good. I'm not even a fan of onions but I decided to use them anyway and the taste was amazing. Will be making again Pros: quick and easy to make delicious Read More

This was very good but I didn't have thighs and I used chicken tenders. I overcooked the chicken but I would make again using thighs. I liked how easy it was. Read More

Adaptations might have detracted Made this with 5 lbs of chicken thighs and legs 4 sweet potatoes 1 large sweet (white) onion. Added extra oil to the potatoes/onions based on other reviewers comments. Alas I only had 2.5T of dried thyme so I added some powdered thyme (mistake?). Also forgot to heat the sheet pan in the oven beforehand which was likely what resulted in zero caramelization. I'd also lined the sheet pan in non-stick foil. Not sure if that affects the process. I roasted the assembled dish in convection-roast mode at 425d. It cooked in precisely the 30 min.(pieces were larger SmartChicken organic). But the lack of caramelization and the fairly strong thyme flavor compromised the dish. To be fair it could be from the errors and compromised ingredients. But it seems like this dish still needed something extra. Pros: Easy quick Cons: Needs something Read More
