Start by cutting the chicken breasts into bite-sized cubes, about 1 inch each. Pat the pieces dry with a paper towel to remove excess moisture; this helps achieve a nice golden sear.
Add chicken pieces to a mixing bowl and sprinkle them with flour, Italian seasoning, salt, and pepper. Toss until all the chicken pieces are evenly coated. This light coating will help form a flavorful crust during cooking.
Preheat your skillet over medium-high heat. Add 1 tablespoon olive oil and 1 tablespoon butter to the pan. Swirl to coat the surface evenly.
Step 4: Sear the Chicken
Place the chicken in a single layer in the skillet. Avoid overcrowding the pan to ensure good airflow and browning. Sear for about 4 minutes on one side until golden brown, then flip and cook another 3–4 minutes on the other side. The chicken should be nearly cooked through.
Reduce the heat to medium-low and add the remaining butter to the skillet. Once melted, stir in the minced garlic. Sauté for 1–2 minutes until fragrant, but be careful not to burn the garlic.
Return the chicken to the skillet, tossing it gently to coat each piece with the garlic butter sauce. Sprinkle fresh parsley over the top. Serve immediately and enjoy your flavorful garlic butter chicken bites!
