Ingredients You’ll Need for Healthy Butternut Squash, Chicken, & Wild Rice Casserole

1 cup uncooked wild-and-brown rice blend
1½ pounds boneless, skinless chicken thighs (trimmed of excess fat)
4 tablespoons extra virgin olive oil (divided)
½ teaspoon kosher salt (divided)
½ teaspoon ground black pepper (divided)
1 small butternut squash (about 1½ pounds)
1 medium yellow onion (diced, about 1½ cups)
1 tablespoon fresh thyme (plus more for garnish)
¾ cup dried cranberries
½ cup shredded Parmesan cheese (about 2 ounces, divided)
½ cup chopped raw pecans or walnuts

How to Make Healthy Butternut Squash, Chicken, & Wild Rice Casserole

Prepare the Rice: Cook the rice blend according to the package instructions. You’ll need around 3 cups once cooked. Set aside.
Cook the Chicken: Preheat your oven to 425°F and place a rack in the center. Line a 9×13-inch baking dish with foil or parchment for easier cleanup. Arrange the chicken thighs in a single layer, tucking any loose edges underneath. Drizzle with 2 tablespoons of olive oil and sprinkle with ¼ teaspoon each of salt and pepper. Roast until the internal temperature reaches 165°F (about 20 minutes). Transfer the chicken to a plate, cover it, and let it rest for 10 minutes. Lower the oven to 350°F and remove the foil or parchment.
Prep the Squash: While the chicken rests, peel the butternut squash. Trim both ends, cut it in half lengthwise, and scoop out the seeds. Dice into ½-inch cubes to yield roughly 4 cups.
Sauté the Vegetables: Heat the remaining 2 tablespoons of olive oil in a deep skillet over medium heat. Add the diced squash and onion, along with the remaining ¼ teaspoon of salt and pepper. Sauté for about 2 minutes until the onion softens. Cover and continue cooking, stirring occasionally, until the squash is fork-tender yet still slightly firm — around 6 to 8 minutes.
Combine the Casserole Base: Cut the rested chicken into bite-sized chunks. Stir this into the skillet with the cooked squash mixture, then add the thyme, cranberries, ¼ cup of Parmesan, and the cooked rice. Mix well to evenly incorporate all the flavors.
Assemble: Spray the same 9×13-inch dish with nonstick spray (no need to wash it). Transfer the mixture into the dish and spread it evenly.
Bake: Bake uncovered at 350°F for 15 minutes. Then top with chopped nuts and the remaining ¼ cup of Parmesan. Continue baking for another 8–10 minutes until the cheese melts and the nuts are golden. Finish with a sprinkle of fresh thyme before serving warm.

Variations & Creative Twists

Spicy Kick: Add a teaspoon of crushed red pepper flakes for some heat that perfectly complements the sweetness of the squash.
Creamy Addition: Stir in a cup of heavy cream or Greek yogurt before baking for an even richer, creamy texture.
Nut Alternatives: Swap out pecans or walnuts for hazelnuts for a unique twist that adds a lovely crunch.
Add Greens: Toss in a handful of fresh spinach or kale when mixing in the chicken for added nutrition and vibrant color.

Chef Emma’s Helpful Tips

Make Ahead: You can prep this casserole a night in advance. Just cover and refrigerate before baking; increase the baking time slightly if baking from cold.
Ingredient Swaps: Don’t have wild rice? Substitute with quinoa or brown rice for a similar texture and hearty feel.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven for the best texture.
Slicing Squash: Use a sturdy knife to slice through the tough skin of the butternut squash, and cook it in the microwave for a few minutes to soften if needed.
