Between two pieces of plastic wrap, pound the halved chicken breasts to an even thickness (about ¼ inch). Season all over with Dijon mustard, ½ teaspoon Italian seasoning, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon salt, and black pepper, to taste. Make sure the chicken is fully coated on both sides.
Dredge each piece of chicken in flour and shake off any excess.
In a large skillet, add the asparagus with ¼ water, cover and cook over medium heat to steam 2 to 3 minutes, until crisp tender. Remove and set aside.
In the same skillet, heat the butter over medium-high heat. Add the chicken and cook for about 4 to 5 minutes per side, or until each piece is cooked through and has a golden-brown crust. Remove and set aside.
Add chicken bone broth, half-and-half, remaining Italian seasoning, ¼ teaspoon salt, garlic powder and onion powder to the pan. Reduce by half over medium-low heat, until it thickens, thick enough that it coats the back of a spoon.
Add the lemon juice and nestle the cooked chicken into the sauce and simmer for a few minutes, until heated through. Finish with lemon zest.
Serve with asparagus, drizzling the sauce over the chicken.
Notes
*Half of the flour gets tossed after, subtracted from the full analysis.Since the sauce is the main component of the dish, flavorful homemade broth or good quality chicken broth is suggested. Brands that sell chicken bone broth, like Kettle & Fire, Butchers by Roli or Epic are suggested. Serving Suggestion: over pasta or rice, with cauliflower rice or cauliflower gnocchi, or roasted baby potatoes.Variations: Instead of asparagus, serve with charred broccoli or green beans.
