Step 1

Slice chicken breasts in half then season generously with salt and pepper.

Step 2

Over medium-high heat in a large skillet, add 1-2 tablespoons of olive oil then once the oil is hot sear the chicken on both sides until it’s nice and browned. This took me about 6 minutes on each side.

Step 3

Once the chicken is browned and mostly cooked through, remove from the skillet and set on a plate. In the same skillet, add the onion and garlic and cook until softened and fragrant. Remove the skillet from the heat for about 2 minutes then add in the tomatoes. Allow tomatoes to soften a bit and the juices to burst then add the basil.

Step 4

Add the chicken back into the skillet and let it warm back up with the “sauce.” Spoon the onion, tomato, basil mixture on top of the chicken then add butter (if using). Remove from heat and serve! Drizzle balsamic vinegar glaze or regular balsamic vinegar on top for extra flavor.
