How Long to Bake Thin Chicken Breast
- At 350°F: 18–22 minutes
- At 375°F: 15–20 minutes
- At 400°F: 12–15 minutes
Thin chicken breasts are done when they reach an internal temperature of 165°F.
Cooking time can vary slightly depending on thickness, so using a meat thermometer is the best way to avoid overcooking.
For best results, choose evenly sized pieces so they cook at the same rate.
While you can buy thin-sliced chicken breasts at most grocery stores, I find it’s easier—and more consistent—to slice them myself. The store-bought kind can be unpredictable. Sometimes they’re so small they barely count as a serving, and other times they’re oversized. Plus, they tend to cost more.
I started cutting my own when I needed evenly sized pieces for dishes like Chicken Parmesan. With just a little practice and a method that works every time, I’ve never looked back. Once you get the hang of it, you’ll love being able to portion them your way and skip the store-bought hassle.

Ingredient Notes
- Chicken Breast: Boneless skinless chicken breasts is the only way to go here.
- Oil: I use olive oil or canola oil. Any oil you like that’ll hold up at 350°. Colorado State has a great article and chart with the smoke point of oil.
- Spices: We like garlic powder, onion powder, smoked paprika, black pepper and salt. Sometimes we use herbs such as Italian seasoning, like I did on these baked chicken breasts.

How to Cut Chicken Breast Into Thin Slices
Lay the chicken breast on a cutting board and hold your knife parallel to the board. Starting at the thickest part of the chicken, slice the chicken as evenly as possible. I always cut one chicken breast into two pieces—no matter how big it is. I find it’s easier to get even slices that way, rather than trying to cut it more than once.
The method I use is simple. I lay my folded index finger (the one holding the knife) on the cutting board and use my knuckle as a guide to keep the knife level. I keep the cutting board close to the edge of the counter so my other fingers don’t get in the way. Then I hold the chicken breast steady with my flat non-dominant hand. Find a method that works best for you.
Before I started doing it this way, it was hit or miss whether I’d get the slices even. Now, I get them pretty close every time. My breast slices usually come out between 4 and 7 ounces each, depending on the size of the breast.
