Preheat your oven to 425°F (220°C). Grease a 9x13 or 10x15 casserole dish.
Place the sweet potato cubes and garlic cloves in the dish. Drizzle with 1 1/2 tablespoons of olive oil, 1/2 teaspoon of salt, 1/2 teaspoon of pepper, and 1 teaspoon of Italian seasoning. Toss to coat and roast for 20 minutes.
While the vegetables are roasting, cube the chicken and season with the remaining salt, pepper, and Italian seasoning.
After 20 minutes, remove the dish from the oven. Add the Boursin cheese and cubed chicken. Drizzle with the remaining olive oil. Return to the oven for 15 minutes.
Cook the orzo in boiling water according to package instructions, reserving at least 1 1/2 cups of the starchy pasta water.
Drain the orzo once cooked. Squeeze the roasted garlic from the peels and mash into a paste. Add the orzo, chopped spinach, and half of the reserved pasta water to the dish. Toss to combine.
Sprinkle with shredded parmesan cheese and optional: broil for 2-3 minutes for a golden finish.
Notes
For a twist, try adding sun-dried tomatoes or roasted red peppers for extra flavor. No alcoholic drinks allowed, please substitute with a non-alcoholic option.
