Step 1

Preheat the oven to 425 degrees F (220 degrees C).

Step 2

Combine butternut squash, fresh sage, Parmesan cheese, 2 tablespoons olive oil, and salt in a bowl. Toss until squash is completely coated and place on the right side of a large nonstick baking sheet (17 1/4 x 11 1/2-inches).

Step 3

Combine horseradish, Dijon mustard, onion powder, and garlic powder in a second bowl. Add chicken thighs and mix until well coated. Place chicken thighs in the center of the baking sheet.

Step 4

Slice zucchini into 16 equal size spears. Place spears on the left side of the baking sheet. In a small bowl mix 1 tablespoon olive oil and balsamic vinegar. Brush olive oil mixture on zucchini and sprinkle with garlic powder and black pepper.

Step 5

Bake in the preheated oven until chicken is no longer pink at the bone and the juices run clear, about 25 minutes. An instant-read thermometer inserted near the bone should read 165 degrees F (74 degrees C).
