Cooking Tips

The Chicken

Chicken tenderloins are significantly higher in fat than other cuts of the bird. That’s part of the reason they’re so tasty.

So, if you’re watching your fat intake then you can use cuts of thigh (less fatty) or breast (least fatty) as a substitute.

The Pan

Use a good non-stick pan for this recipe. They’re easier to control the temperature and keep it medium during cooking, which is critical to maintain the flavors of this dish.

If you’re a confident cook, go ahead and use a cast-iron skillet (but be mindful of controlling the heat).

Brown, Don’t Burn, by Using Moisture

Use your lid to keep moisture in the pan, especially when cooking the veg. Being a one-pan dish, things can heat up quickly and burning the meat and vegetables can compromise the flavor.

I found using the lid is the perfect antidote.

How To Make Lazy Keto Chicken Tenders and Peppers

Printable instructions and measurements are on the recipe card.

Season and Fry The Chicken

Season the chicken tenderloins with salt and pepper before browning in the pan over medium-high heat. You’ll want to heat up a tablespoon of oil before popping the tendies in.

If you think your pan is going to get a bit crowded, consider cooking the tenders in two batches. Sear one half in the oil, before transferring to a plate. Turn the heat under the pan to medium, add another tablespoon of oil, and then brown the other half of the chicken.

Brown the Peppers and Onions

Add the onions and peppers to the hot pan and cover with the lid to trap in the moisture.

Remove the lid to stir, and continue until they’ve softened and browned (approx. 5 – 7 minutes).

Bloom the Seasoning and Add Tomatoes

Adding in the Italian herbs / seasoning and salt before you put any more liquid in will help the seasoning bloom. It’ll take about 30 seconds for the to become fragrant, at which point you should add the vinegar and let most of it evaporate off.

Next, add in the tomatoes and bring to a simmer.

Finish the Chicken Off in the Sauce

Add the chicken tendies back into the pan with any juices, and let simmer on low heat until they’re cooked all the way through.

Add the butter in and stir through. Season with salt and pepper to taste. Finito!
