Creating your Sheet Pan Turkey Breast Dinner is a straightforward process. Simply follow these steps to ensure a delicious outcome:

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C).
2. Prepare the Vegetables: In a bowl, toss the halved potatoes, sliced carrots, green beans, and onion with 2 tablespoons of olive oil, garlic powder, onion powder, thyme, rosemary, salt, and pepper.
3. Season the Turkey: Rub the remaining olive oil over the turkey breast and season it with the same spices you used for the vegetables. Ensure it’s well-coated for maximum flavor.
4. Arrange on the Sheet Pan: Place the seasoned turkey breast in the center of a large sheet pan. Surround it with the prepared vegetables in an even layer.
5. Roast in the Oven: Put the sheet pan in the preheated oven and roast for 40-45 minutes. The turkey should reach an internal temperature of at least 165°F (75°C) when done.
6. Rest the Turkey: Once cooked, remove the sheet pan from the oven and let the turkey rest for about 10 minutes before slicing. This helps retain its juices.
7. Serve and Enjoy: Slice the turkey breast and serve it alongside the roasted vegetables. Garnish with fresh parsley, if desired.

Following these steps will give you a delicious meal that’s both satisfying and easy to prepare.
