This Keto Hot Italian Chicken Skillet is a delicious low-carb skillet dinner filled with tomatoes, olives, hot peppers, and cheese! Just 5 ingredients + a few pantry staples!

What's better than a 5-ingredient recipe?! In the past, we've done entire months of 5-ingredient recipes so we know a thing or two about creating big bold flavors with minimal ingredients. Enter this Keto Hot Italian Chicken Skillet!
Ingredients you'll need:
- chicken
- tomatoes
- banana peppers
- olives
- shredded mozzarella
Plus a few pantry staple ingredients like avocado oil, Italian seasoning, onion powder, and salt. That's it!
This skillet dinner reminds us of an Italian sub in such an awesome way. We ate this with a huge Italian salad and it was delish!


The marinade for the chicken is super simple and is just avocado oil, Italian seasoning, onion powder, and salt! It creates the juiciest chicken and makes sure that this skillet dinner is packed with Italian flavors. It's almost like a submarine dressing without vinegar.
Don't have mozzarella on hand? You can use provolone here too, even sliced instead of shredded. If you're dairy-free, we love Violife mozzarella!

To get a specific serving size you’ll want to weigh the final dish then divide by the number of servings. We can’t provide this information as your cooking style will vary from ours as well as the brand ingredients you choose to use.

How long do you recommend marinating the chicken? I didn't see that step in the recipe, but it's mentioned in the text. Maybe I overlooked it... 🙂
