Bubbly melted bocconcini swimming in a warm and succulent tomato sauce that'll taste like it's been simmering on the stove for hours. There's only one rule when it comes to this Cheesy Chicken Skillet and that is make sure you don't forget the bread!
In a large ovenproof skillet (I use a cast iron), heat half the olive oil over medium-high heat. Add the chicken breasts.
Sear, turning once, to ensure that both sides are lightly browned and golden. This should take about 10-15 mins, depending on how big your breasts are (or what kind of chicken you're using).
Once both sides have a nice sear, transfer the chicken to a paper towel lined plate until ready to use.
Reduce the heat to medium. Toss the onions in the skillet.
Sautée a few minutes, stirring frequently, until soft and beginning to turn translucent. Add garlic and stir until fragrant, an additional 30 seconds.
Add the canned tomatoes, Italian seasoning, chilli flakes (if using) and more salt and pepper. Bring to a boil, then reduce the heat to a simmer.
Stir in tomato paste and allow the flavours to come together.
Using the back of a wooden spoon or spatula, break up the whole tomatoes into smaller bite sized chunks.
Leave it simmering, uncovered, for 10-15 minutes.
Stir in a few tbsp of fresh shredded basil.
Make two wells in the tomato sauce and return the chicken to the skillet. Sprinkle with parmesan cheese and put the 2 fresh sprigs of Oregano in the sauce - one on each side of the breasts.
Bake, uncovered, for 25-30 mins, until the chicken is no longer pink and fully cooked through.
Remove the skillet from the oven and add the mini bocconcini around the chicken breasts (I lightly press each one into the sauce).
Throw it back in the oven for 5 minutes and broil for an additional 3, keeping a close eye to ensure they don't burn. Everything should be nicccce and bubbly at this point.
Top with more grated parmesan, fresh basil and a few cracks of salt and pepper.
DO NOT forget the bread for dipping!!!
Notes
The chicken is done when it reaches an internal temperature of 165°F. However, keep in mind that you have an additional 8 minutes of oven time after the initial 25-30 minutes.
