Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 2 cups (about half) of the cubed butternut squash with 1 tbsp olive oil, 3 smashed garlic cloves, 1/2 tsp sea salt, 1/4 tsp black pepper, and 1/2 tbsp chopped rosemary. Spread on a baking sheet and roast for 25 minutes until tender and caramelized.
  2. Step 2: While squash roasts, pat dry 4 bone-in skin-on chicken thighs and season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat. Place chicken skin-side down and sear for 6-7 minutes until skin is golden and crispy.
  3. Step 3: Flip chicken thighs and cook for 6 more minutes until internal temperature reaches 165°F. Remove skillet from heat and set chicken aside to rest.
  4. Step 4: In the same skillet, add the remaining cubed butternut squash, 3 smashed garlic cloves, 1/2 tbsp olive oil, 1/2 tbsp rosemary, and sauté over medium heat for 5 minutes until tender and fragrant.
  5. Step 5: Plate the chicken thighs with both batches of roasted and sautéed butternut squash. Drizzle 1 tbsp fresh lemon juice over everything for brightness and serve immediately.
