Preheat oven to 400°F.
Place chicken and squash on a large baking sheet.
In a small bowl, whisk olive oil, lemon juice, garlic, oregano, thyme, salt, and pepper.
Pour mixture over chicken and squash, tossing to coat evenly.
Roast for 30–35 minutes, flipping once, until chicken is cooked through and squash is tender and lightly caramelized.
Serve immediately or portion for the week.
