1. Prepare the Chicken: Place the chicken breasts between two sheets of plastic wrap and gently pound them to an even thickness using a meat mallet. Season both sides with 21 Salute Seasoning (or poultry seasoning), salt, and freshly ground black pepper.
2. Sear the Chicken: In a large skillet, heat the olive oil over medium-high heat. Add the seasoned chicken breasts and cook for about 5 minutes on the first side, until golden brown. Flip and cook for an additional 5 minutes on the other side, ensuring the chicken is cooked through and reaches an internal temperature of 165°F (74°C). Once done, transfer the chicken to a plate and set aside.
3. Create the Garlic Butter Sauce: In the same skillet, add the dry white wine (or chicken broth) to deglaze the pan, scraping up any browned bits from the bottom. Reduce the heat to medium, add the unsalted butter and minced garlic, and cook for about 1 minute, stirring constantly, until the butter is melted and the garlic is fragrant.
4. Combine and Serve: Return the cooked chicken breasts to the skillet, turning them to coat evenly in the garlic butter sauce. Allow them to simmer briefly to absorb the flavors. Garnish with chopped fresh parsley, if desired, and serve immediately.
