How Long to Cook Chicken at 300 Degrees

Cooking chicken is a staple in many households, and it can be prepared in various ways. However, cooking it properly requires proper timing and temperature regulation. One popular cooking method for chicken involves baking it in the oven at a lower temperature of 300 degrees Fahrenheit. This method ensures that the chicken is evenly cooked and remains tender. In this article, we will discuss how long to cook chicken at 300 degrees by covering various factors affecting cook time, preparation techniques, oven settings, and tips and tricks.

Factors Affecting Cooking Time

Before discussing cooking time for different cuts of chicken at 300 degrees, it’s important to highlight various factors that affect the cook time of chicken. These are:

Different Cuts of Chicken

How long you cook your chicken depends on the cut you choose. Different cuts of chicken vary in size and thickness, hence they require different amounts of time to cook properly. Typical cuts used for baking include boneless, skinless chicken breasts, whole chickens, and chicken thighs.

  • Boneless Chicken Breasts: These take about 20-25 minutes to bake at 300 degrees.
  • Whole Chickens: Cooking a whole chicken can take up to two hours or more if the chicken is particularly large.
  • Chicken Thighs: Chicken thighs at around five ounces per piece can take up to 45 minutes to bake at 300 degrees.

Weight and Size of Chicken

The weight and size of the chicken also play important roles in determining how long you will need to bake it. The larger and heavier the chicken, the longer it will take to cook through. On the other hand, smaller and lighter chickens will cook more quickly.

  • Weighing the Chicken: Before cooking, it’s essential to weigh your chicken to ensure accurate cook time. To weigh your chicken, clean it and pat it dry before placing it on a kitchen scale.
  • Calculating Cook Time Based on Weight: To determine how long you need to bake your chicken based on weight, follow this general rule of thumb: bake for 20-30 minutes at 300 degrees per pound of meat.
  • Differences in Cooking Time for Small vs. Large Chickens: To illustrate the differences between small and large chickens, let’s say that a four-pound chicken would bake for roughly 80-120 minutes, while an eight-pound chicken would take around 160-240 minutes.

Desired Level of Doneness

Cooking your chicken to your desired level of doneness is essential, whether you want a well-done or medium-rare finish. The internal temperature of cooked chicken should reach at least 165 degrees Fahrenheit for safety reasons.

  • Cooking Temperatures for Different Levels of Doneness: Depending on your preference, there are different temperatures that you can aim for when baking chicken at 300 degrees. For example:
    • – Juicy and tender: reached at an internal temperature of approximately160 degrees Fahrenheit.
    • – Well Done: reached at an internal temperature of approximately185 degrees Fahrenheit.
  • Using a Meat Thermometer to Check Internal Temperature: To make sure your chicken is fully cooked, ensure that you have a meat thermometer on hand. Insert it into the thickest part of the chicken to determine its internal temperature. Make sure it reads at least 165 degrees Fahrenheit.

Preparing Chicken

To ensure that your chicken is delicious, moist, and flavorful when baked at 300 degrees, you need to prepare it well beforehand. This includes seasoning or marinating the chicken and trussing a whole one.

Seasoning and Marinading

Seasoning and marinading add flavor and moisture to chicken before baking. You can use different herbs, spices, condiments, or oils depending on your preferences.

  • Importance of Seasoning and Marinading: Marinating your chicken for some hours or overnight helps keep it moist during cooking. The marinade also adds flavor and enhances the taste of your chicken once cooked.
  • Examples of Seasoning/Marinade Blends:You can marinate your chicken in various ingredients such as; olive oil mixed with lemon juice and herbs like rosemary or thyme. Cumin, coriander, paprika, chili powder garlic, soy sauce, honey combo creates a sweet, spicy blend that works great with baked chicken as well.

Trussing Chicken

If you’re baking a whole chicken at 300 degrees, trussing your bird can help distribute heat evenly throughout the meat.

  • What is Trussing? Trussing is tying up a bird’s wings and legs tightly before baking to keep everything in place and prevent scorching parts of the meat.
  • Why Truss Whole Chickens? Whole chickens contain different parts that cook at different rates. Trussing a whole bird ensures that it cooks evenly.

Oven Settings and Cooking Time

Determining the correct oven temperature for baking chicken at 300 degrees and how long you’ll need to bake it for depends on various factors previously highlighted. Below, we will discuss oven temperature and cooking times for different cuts, sizes, and levels of doneness.

Oven Temperature

Baking chicken at 300 degrees is a low-heat cooking method that is perfect for roasting or slow-cooking. It’s essential to set your oven temperature to precisely 300 degrees before preheating it, ensuring that it reaches the desired temperature before baking.

  • Setting Oven Temperature to 300 Degrees: Turn your oven dial to the setting labeled ‘300’ if it’s an older model.
  • Explaining Variations in Oven Temperature: Different brands of ovens might display different temperatures compared to others. In such cases, use a thermometer to monitor the oven’s actual heat settings.

Cooking Times for Different Cuts, Sizes, Levels of Doneness

Depending on whether you’re cooking boneless chicken breasts, whole chickens, or chicken thighs, your cook time will vary. Additionally, your choice of doneness will play a role in determining how long you need to bake your chicken for.

Boneless Chicken Breasts:

Bake boneless chicken breasts at 300 degrees for about 20-25 minutes until an internal temperature of 165°F is reached.

Whole Chickens:

Cooking a whole chicken requires a little more time, but it’s worth it. The oven should be preheated and set to 300 degrees Fahrenheit before baking. It’s best to estimate your cook time by assigning roughly 20-30 minutes per pound of meat, occasionally basting the chicken every 20 minutes with its juices while cooking. Using a thermometer to check for an internal temperature of 165°F at the thickest part of the bird then helps determine whether it’s ready or requires further baking.

Chicken Thighs:

Chicken thighs are a favorite recipe among many for baked dishes. You can bake them at 300 degrees until they’re golden brown and have an internal temperature of 165°F. The cook time typically ranges between 40-45 minutes depending on thickness.

Tips and Tricks

Cooking juicy and flavorful chicken at 300 degrees isn’t rocket science, yet some tricks can make all the difference in your final dish.


To keep your chicken moist during baking, consider basting it with its juices every few minutes or so. Alternatively, brine the chicken beforehand to help maintain its moisture during cooking.

Resting Period

A rest period after cooking is essential in ensuring that the juices redistributed within the meat remain where they should be instead of leaking onto your plate. Cover your baked chicken with foil and let it rest for roughly ten minutes before cutting into it, and voila!


Carving into boneless chicken breasts is simple because they’re fairly flat while cutting a whole bird may require some practice. Once you’ve let your bird rest for approximately ten minutes, remove the trussing string if applied, then cut off the legs and wings and finally slice the breast.


Baking chicken at 300 degrees is an excellent way to ensure that your poultry cooks evenly and remains juicy and moist. The length of time it takes to cook chicken will depend on various factors such as weight, cut, and oven temperature. To keep your chicken flavorful and moist while cooking, consider seasoning or marinating it first and basting or brining it before baking. Use a thermometer to ensure that the poultry has reached an internal temperature of 165°F before carving into it, let it rest afterward for several minutes, then serve up your delicious chicken with your favorite side dishes.
