Calling all the colors! Empty your refrigerator of vegetables and juice some lemons, 'cause this healthy Sheet Pan Chicken with Rainbow Veggies is here for the win!
1 medium sweet potato — scrubbed and diced into 1/2-inch-wide pieces
3 tablespoons Avocado Oil (or high-heat tolerant) — divided
1 1/4 teaspoons kosher salt — divided
3/4 teaspoon black pepper
1 1/4 pounds chicken breasts — cut into bite-size pieces (about 2 medium breasts or you can use thighs)
1 small head broccoli — cut into florets (about 2 cups florets)
1 red bell pepper — cored and cut into 1/2-inch pieces
1 zucchini — halved lengthwise, then cut into 1/2-inch-thick half moons
1 yellow squash — halved lengthwise, then cut into 1/2-inch-thick half moons
zest and juice of 1 medium lemon
2 1/2 teaspoons Italian seasoning
1 teaspoon garlic powder
1 teaspoon onion powder
1/4 cup freshly grated Parmesan cheese
Place a rack in the center of the oven and preheat the oven to 400 degrees F. For easy cleanup, line a large, rimmed baking sheet with parchment paper or silpat. Lightly coat with nonstick spray if using parchment.
Place the sweet potatoes in a large bowl. Drizzle with 1 tablespoon avocado oil and sprinkle with 1/4 teaspoon kosher salt and 1/4 teaspoon black pepper. Toss to coat and then spread into a single layer on the baking sheet. Keep the bowl handy. Bake for 10 minutes, or until the sweet potatoes are just beginning to soften on the outsides but are still too firm to eat.
Meanwhile, in the bowl that you used previously for the sweet potatoes, place the chicken, broccoli, bell pepper, zucchini, and yellow squash. Drizzle with the remaining 2 tablespoons avocado oil. Add the lemon zest and juice, Italian seasoning, garlic powder, onion powder, and remaining 1 teaspoon salt and 1/2 teaspoon pepper. Toss to coat.
Transfer the chicken and vegetable mixture to the sheet pan with the sweet potatoes, using a spatula to spread everything into an fairly even layer and stirring it a bit if needed.
Return to the sheet pan to the oven and bake for 15 to 20 additional minutes, stirring once halfway through, until the chicken is cooked through and no longer pink in the middle and the vegetables are tender but not mushy. (They won’t be browned and caramelized but will be delicious to eat.) Sprinkle with Parmesan. Serve hot.
