How Long to Cook Chicken at 400


In my house, Sunday means chicken. It’s a family tradition that goes back to my mom’s childhood in the South, where she learned to make fried chicken that was so good it could bring tears of joy to your eyes. Weeknight chicken dinners are far less glamorous, but they’re just as important. I always try to keep a few boneless breasts on hand for easy weeknight meals—they’re cheaper than thighs or drumsticks and cook faster than whole birds. But what temperature should you set your oven at? And how long should you cook them for?

Whole Chicken

When it comes to chicken, the best way to cook it is in a slow cooker. Slow cookers are great because they’re easy and convenient, but they also allow you to keep your kitchen cool while still serving up delicious meals.

1 whole chicken (about 3 lbs)

1/2 cup water or broth

Boneless Skinless Breasts


Boneless skinless breasts are a good option for the novice cook. They’re easy to prepare, and the cooking time is not too long. In general, you should expect to cook boneless chicken breasts in an oven at 400 degrees Fahrenheit until they reach an internal temperature of 165 F (74 C). The exact amount of time will depend on several factors:

  • The thickness of your meat – If it’s too thick, it may not cook all the way through before becoming dry; if it’s too thin and small than usual for its size category (e.g., if you bought some pre-cut pieces), then there’s a risk that these pieces will overcook during their journey from raw through fully cooked!

Bone-In Breasts

You should expect your bone-in chicken breasts to take about 20 minutes to cook through. If you’re looking for a longer cooking time, you can reduce the heat by 25 degrees and let them go for an additional 10-15 minutes.

If you want boneless skinless chicken breast, it may take less than 20 minutes to cook thoroughly; however, if you’re using bone-in skinless breasts or thighs (which are often more dense than their counterparts), they’ll need more time in order to reach an internal temperature of 165F/74C.

Boneless Thighs or Leg Quarters

Cooking time will vary depending on the thickness of your boneless thighs or leg quarters. The thicker they are, the longer they’ll take to cook through. If you’re using a convection oven, which circulates air around food while it cooks at a lower temperature than a conventional oven, then your chicken should be done cooking sooner than if you were using a conventional oven set at 400 degrees Fahrenheit (200 degrees Celsius).

Boneless Chicken Breast Halves

  • Boneless Chicken Breast Halves
  • Cook time: 12-15 minutes
  • Servings: 4 breasts at a time (or 2 whole chickens)
  • Heat the oven to 400 degrees F. Place the chicken breasts in a baking dish and bake for 12-15 minutes, until they reach an internal temperature of 165 degrees F.

It depends on the thickness of the meat and the exact temperature of your oven.

The first thing to consider is the thickness of your chicken. The thicker it is, the longer it will take to cook. To determine how long it will take for your chicken to cook in an oven at 350 degrees Fahrenheit (177 Celsius), divide by two and add 30 minutes if you’re using bone-in meat or 20 minutes if you’ve removed the bone from a whole chicken breast.

If your oven has an accurate temperature gauge on its control panel, then use this information when calculating how long to cook chicken at 400 degrees Fahrenheit (204 Celsius). However, most home ovens don’t have accurate gauges so they may run hotter or colder than their advertised temperatures–meaning that even if your recipe says “cooking time: 10 minutes per pound,” this could be off by as much as 25%.

It’s also important not only know what kind of meat you’re cooking but understand what type of cut comes from each part of an animal–which means knowing which section contains muscles used primarily for movement versus those used mostly for supporting weight during flight/swimming/etcetera
