Ingredients
- 1 large sweet onion
- 1 cup balsamic vinegar (preferably aged)
- ¼ cup olive oil
- 1 tablespoon rosemary (crushed)
- 1 tablespoon Italian seasoning blend
- 2 teaspoons onion powder
- 1 teaspoon garlic powder
- ¼ teaspoon black pepper
- ½ teaspoon sea salt
- 16 ounces tomatoes (grape tomatoes work best)
- 4 pounds boneless, skinless chicken thighs (as local as possible)
- Shaved Parmesan cheese to taste (optional)
Instructions
Preheat the oven to 375 degrees.
Remove the skin of the onion. Cut the onion in half and then cut it into thin wedge-like slices. Make sure to separate the onion pieces. Whisk the balsamic vinegar, olive oil, rosemary, Italian seasoning, onion powder, garlic powder, black pepper and sea salt together in a glass bowl. Use ⅓ of the mixture to coat the tomatoes and onion slices. Drizzle the remaining balsamic mixture on the boneless thighs, and let them marinate for 15 minutes. Spread the tomatoes, onions and chicken thighs onto a large nonstick baking sheet that has been coated with olive oil nonstick cooking spray. Pour any remaining juice on top. Bake for approximately 30 minutes, until the center of the chicken measures 170 degrees. Top with shaved Parmesan cheese if desired.
