Set the chicken out at room temperature. If it’s not already in thin slices, cut the breasts lengthwise through the middle to make them fairly thin. If any pieces are really uneven (thicker in one part, thinner in another), use a meat mallet or just a heavy pan to smash down the thick parts and even them out.
4 boneless, skinless chicken breasts
Season both sides of the chicken breasts with salt, pepper, and the garlic powder. Place flour on a plate or in a shallow bowl. Dredge each piece of chicken through the flour to lightly coat on both sides, and shake to remove any excess.
kosher salt and black pepper, 3/4 teaspoon garlic powder, 1/4 cup all-purpose flour
Melt 1 Tablespoon of the butter together with the olive oil in a large skillet over medium-high heat. Add chicken and sauté for 3-4 minutes on each side, until golden and cooked through. Transfer chicken to a clean plate and reduce the temperature to medium-low.
2 Tablespoons butter, 1 Tablespoon olive oil
Add the remaining 1 Tablespoon butter and minced garlic to the skillet. Cook for about 30 seconds, just until fragrant, then add the wine, broth, and Italian seasoning. Scrape the bottom of the pan to release any browned bits. Increase heat to medium and let the sauce simmer gently for 3-4 minutes.
3 cloves garlic, 1/2 cup dry white wine, 1/4 cup low-sodium chicken broth or stock, 1/4 teaspoon Italian seasoning
Stir in the cream and Parmesan. Cook for 1-2 minutes more, until even and slightly thickened, then stir in the spinach.
3/4 cup heavy cream, 2 cups loosely-packed fresh baby spinach, 1/4 cup grated Parmesan cheese
Return chicken to the pan and spoon some of the sauce on top of each piece. Let it bubble for another 1-2 minutes, just until the chicken is warmed through and the spinach is wilted. Season with more salt and pepper to taste, and serve right away with more Parmesan as desired. Enjoy!
