How to Cook Thin Sliced Chicken Breast in the Oven at 400 Degrees


Cooking chicken properly is not just a matter of taste, but also of health. In this article, we’ll discuss the specifics of cooking thin sliced chicken breast in the oven at 400 degrees. We’ll cover everything from what thin sliced chicken breast is, how to prepare it for baking, the actual cooking process, and some additional tips and guidelines. We’ll also answer some frequently asked questions about cooking thin sliced chicken breast.

What is Thin Sliced Chicken Breast?

Thin sliced chicken breast is simply a chicken breast that has been sliced to a thinner thickness. This has several benefits:

  • It cooks faster: Because of its thinner size, heat can penetrate it more quickly, reducing the overall cooking time.
  • It absorbs marinade better: The increased surface area allows for better absorption of marinade, leading to more flavorful chicken.
  • It’s easier to portion: Thin sliced chicken breast is easier to portion out, making it ideal for meal prep or serving a large number of people.

Preparing Thin Sliced Chicken Breast for Baking

Before you start cooking, it’s important to preheat the oven to 400 degrees. This ensures that the chicken cooks evenly. An oven that hasn’t been preheated might cook the chicken unevenly, leading to parts that are overcooked and dry, and parts that are undercooked and potentially unsafe to eat.

Next, consider marinating the chicken. This can include a variety of ingredients, such as:

  • Olive oil: This helps to keep the chicken moist during cooking.
  • Lemon juice: This adds a tangy flavor and helps to tenderize the chicken.
  • Garlic: This adds a savory depth of flavor.
  • Herbs and spices: These can be adjusted according to your personal preference. Some popular options include rosemary, thyme, paprika, and cayenne pepper.

After marinating, arrange the chicken on a baking sheet. It’s best to use a non-stick sheet or to lightly grease the sheet to prevent sticking. You can also use parchment paper for easy clean-up.

Cooking Thin Sliced Chicken Breast in the Oven at 400 Degrees

Now, let’s get to the main part: cooking the chicken. Here’s a step-by-step guide:

  1. Preheat the oven to 400 degrees.
  2. Place the marinated chicken on a baking sheet.
  3. Bake for 15-20 minutes, or until the internal temperature reaches 165 degrees Fahrenheit.

It’s important to note that the cooking time can vary depending on the thickness of the chicken and the accuracy of your oven’s temperature. Always check the internal temperature of the chicken to ensure it’s fully cooked. You can do this with a meat thermometer. The USDA recommends an internal temperature of 165 degrees Fahrenheit for chicken.

Tips and Guidelines for Baking Thin Sliced Chicken Breast

Here are some additional tips for baking thin sliced chicken breast:

  • Always use a meat thermometer to check the doneness of the chicken. This is the most reliable way to ensure that the chicken is fully cooked and safe to eat.
  • If you’re using bone-in chicken breasts, you’ll need to increase the cooking time. This is because bone-in chicken takes longer to cook than boneless chicken.
  • If the chicken is not fully cooked after the recommended time, continue baking and check the temperature every few minutes. It’s better to cook the chicken a little longer than to risk undercooking it.


Here are some common questions about cooking thin sliced chicken breast:

  • How long should I marinate the chicken? At least 30 minutes, but you can marinate it for up to 24 hours for more flavor. The longer you marinate the chicken, the more flavorful it will be.
  • Can I cook frozen chicken breast? It’s best to thaw the chicken before cooking it. Cooking frozen chicken can lead to uneven cooking.
  • What should I serve with baked chicken breast? Baked chicken breast is versatile and can be served with a variety of sides. Some popular options include roasted vegetables, mashed potatoes, and salad.
