Skinny Sheet Pan Chicken with Mushrooms and Onions – Fast, EASY, HEALTHY, and a FLEXIBLE recipe based on what you have on hand!! A ONE-PAN meal with zero cleanup is the best kind of meal, especially for busy weeknights!!
Easy Sheet Pan Chicken Dinner Recipe
I love sheet pan dinners because they’re easy, tasty, and ready in no time.
The chicken in this recipe is tender, juicy, and infused with flavor from the red onions, paprika, oregano, and fresh parsley.
I love biting into the whole baby portobello mushrooms. Their succulent juicy texture is everything for me and their flavor from roasting alongside the red onions is fabulous.
This accidentally skinny chicken dinner gets bonus points for having lean protein, vegetables, it’s naturally gluten-free, and it’s as easy as throwing everything on a sheet pan and in 20 minutes, dinner is served.
I used two pounds of chicken for this recipe to ensure for planned leftovers but you can easily scale that down if desired and bake a few minutes less.
Ingredients in Sheet Pan Chicken with Assorted Vegetables
To make the roasted chicken and veggies, you’ll need:
- Chicken breasts
- Red onion
- Baby portobello mushrooms
- Olive oil
- Kosher salt and pepper
How to Make Skinny Roasted Chicken and Veggies
This sheet pan chicken and vegetables recipe couldn’t be any easier! I recommend lining a sheet pan with foil for easier cleanup, then add the chicken and veggies, drizzle with olive oil, and season before baking.
Bake until the chicken is cooked through and the vegetables are tender. Finish it off with a bit of fresh parsley and dig in!
Are Mushrooms Mandatory?
No they are not! I know they can be a bit of a controversial food and people either love them or hate ’em! If you’re not a fan or your family isn’t a fan, feel free to omit them.
I used baby portobellos because I tend to have them on hand but if you have some fancier versions of fresh mushrooms, you can try them and see how they work. However, since I haven’t experimented with other varieties, I can’t give guidance how they will turn out.
Tips for Making The Best Sheet Pan Chicken
The great thing about sheet pan meals is that they’re really flexible. In this particular sheet pan recipe I used mushrooms, red onions, and zucchini because that’s what I had on hand and was craving.
My daughter is not a fan of mushrooms and if you have a ‘shroom hater in your group, you can easily pick around them. I keep the mushroom whole for two reasons. First, they don’t overcook and secondly they are easy to pick around for those selective eaters among us.
Feel free to get creative with the vegetables you incorporate. Other vegetables that would be great include broccoli, cauliflower, yellow squash, sugar snap peas, carrots, or bell peppers.
Keep the vegetables chunkier than you think you need to because otherwise they’ll have a tendency to overcook in the form of becoming mushy (zucchini) or burnt (almost all other vegetables, especially broccoli florets).
If you have a convection oven, use it. You don’t need to alter or reduce the temperature but I recommend rotating your pan once halfway through to ensure more even cooking.
- 1.50 to 2 pounds boneless skinless chicken breasts, cut into bite-sized pieces
- 1 large red onion, cut into large chunks
- 8 ounces baby portobello mushrooms (white button mushroom may be substituted; I keep them whole so they don’t overcook)
- 1 medium/large zucchini, cut into large bite-sized pieces
- 3 tablespoons olive oil
- 1 teaspoon paprika, or to taste (smoked paprika may be substituted)
- 1/2 teaspoon dried oregano, or to taste
- 1 teaspoon kosher salt, or to taste
- 3/4 teaspoon freshly ground black pepper, or to taste
- 1 to 2 tablespoons fresh parsley (I used flat-leaf), finely minced for garnishing, or to taste; optional (basil, thyme, or other fresh herbs may be substituted, to taste)
- Preheat oven to 425F (use Convection if you have it, you don’t have to reduce the temp) and line a baking sheet with aluminum foil for easier cleanup (recommended).
- Add the chicken, red onion, mushrooms with the stem/gill side facing up, zucchini, evenly drizzle with olive oil, evenly season with paprika, oregano, salt, pepper, and toss with your hands very well to coat evenly.
- Bake for about 20 minutes or until chicken is cooked through and vegetables are tender. Cooking time will vary based on the thickness of the chicken, if you used 2 full pounds, the size of your other vegetables, and being that this is quite a hot oven, check starting at 15 minutes and often so you don’t overcook the chicken which can dry out quickly. I recommend rotating your baking sheet midway through roasting to ensure even cooking, especially if you’re using a convection oven.
- Optionally garnish with parsley and serve immediately. Extra will keep airtight in the fridge for up to 5 days or in the freezer for up to 4 months.
