Easy Oven Baked Chicken Breast

Oven Baked Chicken is so easy to make. I have been making it almost every Sunday for meal prep for as long as I can remember.

Because all you need to do is mixing the chicken with oil and seasoning in a bowl, bake and enjoy.

However, for a while, I was doing it all wrong.

In fact, it is very easy to overcook the chicken breast, which could result in rubbery or dried-out meat.

So, these are a few things I have learned from my own mistakes.

First, bake the chicken breast at a high temperature, above 400F.

Secondly, don’t cover the oven-baked chicken breast.

I used to think I was doing the baked chicken breast justice to cover it in order to trap the moist in. But it is the complete opposite. By covering the chicken you actually start a “steaming” process, which leads to rubbery and dry chicken meat.

Thirdly, let the chicken breast rest before cutting it up.

How to Make the Best Oven Baked Chicken Breast

There are so many ways you can season chicken breast. It is like a blank canvas.

In this healthy recipe, I will share one of my favorites – Rosemary, Garlic, and Lemon.

And also because my husband has proudly harvested some fresh and fragrant rosemary from our little herb garden. Thanks, Tom!

Ingredients for the best oven baked chicken breast

  • Chopped fresh rosemary
  • Chopped fresh garlic
  • Lemon
  • Onion Powder
  • Paprika
  • Salt and pepper
  • Chicken Breast
  • Arrowroot Flour
  • Avocado oil

Avocado oil has a high smoking point. Since we are going to roast the chicken breast at a very high temperature in the oven, you certainly do not want your smoke alarm to go off. Any other oil with a high smoking point will work as well.

Step-by-step instructions

First, chop rosemary and garlic finely, then mix with the dry spices.

Second, in a mixing bowl, combine 2 lbs chicken breast, avocado oil, seasoning, and arrowroot starch.

Third, mix everything with your hands until well combined.

Then, in an avocado oil greased pan, line up the chicken breast. Squeeze half a lemon on top.

Bake 450 F for 12 – 18 minutes depending on the thickness and the amount of chicken you are using.

Last but not least, let the roasted chicken sit for at least 10 minutes before cutting into it.

Why adding Arrowroot Starch to Oven Baked Chicken Breast

I learned this trick from my dad, who is the best cook in my family. He always mixes in a little bit of starch when seasoning protein. Starches help to trap in the moist.

This is especially important when it comes to chicken breast since it’s so low in fat and therefore tends to dry out so easily. Mixing in a little starch really helps to develop that juicy and tender texture.

Additionally, arrowroot starch is paleo and whole 30 compliant. I love using it in so many recipes. It also makes the best Asian sticky sauce (check out my sticky meatballs here).

What Temperature to Bake the Chicken Breast

Like I said, I learned from my own mistakes over the years of making oven-baked chicken breast.

And I have discovered that you will get the best result if you cook the chicken at
425 F – 450 F.

Roasting chicken breast at a high temperature gives the meat a crispy crust on the outside, and juicy moist meat on the inside.

Depending on the thickness of the chicken breast you are cooking, baking at 450 F only requires 12 – 18 minutes.

Tip: For me, 15 minutes are always a safe option for the average store-bought chicken breasts. You could also use a cooking thermometer to test the inside of the chicken breast. It should be around 160 – 165 F.

Can I Freeze Oven Baked Chicken?
