Prep the chicken: Slice each chicken breast in half lengthwise (cut completely all the way, not butterflied). Place on a piece of plastic wrap, then lay another piece of plastic wrap on top of the chicken, and pound to about 1/4-inch thickness. Mix seasonings together in a bowl and season both sides with seasonings, then lightly dredge in flour, shaking off excess.
2 large boneless, skinless chicken breasts, 1 tsp. kosher salt, 1 tsp. garlic powder, 1/2 tsp. onion powder, 1/4 tsp. black pepper, 1/4 tsp. MSG, 1/2 cup all-purpose flour
Sear the chicken: Heat olive oil in a large skillet over medium-high heat. Cook the chicken for 2-3 minutes per side Start Timer, until golden brown and cooked through. Transfer to a plate and set aside. Work in batches to avoid overcrowding the skillet. Carefully wipe out the pan if needed, leaving a few of the brown bits behind.
2-3 Tbsp olive oil
Build the sauce: Reduce the heat to medium. Deglaze pan with a small splash of wine. Add garlic and sauté for ~30 seconds. Pour in wine and scrape up browned bits from the pan. Reduce for 3 minutes and allow the garlic to cook into the wine. Start Timer. Then add chicken broth, lemon juice, and capers. Simmer for another 3-4 minutes. Start Timer Add a touch more wine or broth if needed.
3 cloves garlic, 1/2 cup dry white wine, 1/2 cup chicken broth, 1/4 cup fresh lemon juice, 2-3 Tbsp capers
Finish the sauce: Lower the heat and stir in cold butter until melted and the sauce is glossy.
2-3 Tbsp cold unsalted butter
Bring it all together: Return chicken to the pan and spoon sauce over top. I like to give the pan a tilt to get the sauce and spoon it evenly over the chicken. Be sure to simmer for 1-2 minutes Start Timer until warmed through so the sauce has time to thicken slightly. Garnish with fresh parsley and lemon zest if using, and serve immediately with pasta of choice, mashed potatoes, orzo, or crusty fresh bread. 2 Tbsp. chopped fresh parsley, Lemon zest
