Ingredient Notes
- Chicken: try to select pieces close in size for even cooking.
- Italian seasoning: typically oregano, basil, rosemary, thyme, marjoram, or sage.
- Olive oil: regular or store brand works. Canola or vegetable oil is fine too.
- Garlic powder: not garlic salt.
How to Make Oven-Baked Chicken Breast
- Preheat oven to 350°F. Line a rimmed baking sheet with parchment paper or foil (optional for easier cleanup).
- Trim any fat from the chicken breasts.
- In a large bowl, mix olive oil, Italian seasoning, garlic powder, salt, and pepper. Rub the mixture evenly over the chicken.
- Place the chicken in a single layer on the baking sheet.
- Bake for 30–45 minutes, depending on size, until the internal temperature reaches 165°F.
- Let rest for 10 minutes before slicing or serving.
How Long to Bake Chicken Breast at 350°F
The baking time depends on the size of your chicken breast. Use the chart below as a guide:
- 6–8 ounces: 30 minutes
- 10–12 ounces: 35 minutes
- 12–14 ounces: 40 minutes
- 16–18 ounces: 45 minutes
Tip: Always check the internal temperature with an instant-read thermometer. It should reach 165°F in the thickest part of the breast.
Tips & Shortcuts
- Use a kitchen scale to pick similarly sized pieces for even cooking.
- Check doneness: if you don’t have a thermometer, cut into the thickest part — juices should run clear.
- Flavor variations: try chili powder, cumin, lemon pepper, onion powder, BBQ rub, smoked paprika, cayenne, or fresh herbs like thyme, rosemary, oregano, basil, or sage.
