Ingredients
Method
- Prep time is 15 minutes, cook time is 20 minutes, and the recipe serves 4. Place the chicken breasts on a cutting board and slice each one horizontally into two thin cutlets. Pat them dry with paper towels. Season both sides with 3/4 teaspoon salt, the black pepper, and Italian seasoning.
- Heat the olive oil in a large 12-inch skillet over medium-high heat. When the oil shimmers, add the chicken in a single layer. Cook for 3 to 4 minutes per side, until the cutlets are browned and the thickest part reaches 165°F. Move the chicken to a plate and loosely cover it with foil.
- Lower the heat to medium. Add the sliced onion to the same skillet and cook for 2 minutes, stirring to loosen the browned bits. Add the garlic and cook for 30 seconds. It should smell fragrant, but it shouldn’t turn dark.
- Stir in the cherry tomatoes, chicken broth, tomato paste, balsamic vinegar, red pepper flakes, and the remaining 1/4 teaspoon salt. Scrape the bottom of the pan with a wooden spoon, then simmer for 5 to 6 minutes. The tomatoes should look softened and glossy, with a few beginning to split.
- Return the chicken and any juices from the plate to the skillet. Spoon the tomato sauce over the cutlets and simmer for 2 minutes, just until the chicken is hot again.
- Turn off the heat. Stir in the butter and chopped basil. Sprinkle with Parmesan, if using, and add more basil and a squeeze of lemon before serving.
Notes
Slice the chicken evenly and dry it before seasoning so it browns instead of steaming. Do not crowd the skillet; use two batches if needed. Check the thickest part with a thermometer and cook to 165°F. Add basil after turning off the heat. Refrigerate leftovers within two hours and use them within 3 to 4 days.
