Place chicken breasts between two sheets of plastic wrap or in a large ziplock bag. Use a meat mallet or rolling pin to pound them to an even thickness of about 1/2 inch.
Season the chicken breasts generously with salt and pepper on both sides.
In a shallow dish, combine the all-purpose flour, garlic powder, Italian seasoning, salt, and pepper. Mix well.
In another shallow dish, beat the eggs.
In a third shallow dish, combine the grated parmesan cheese, panko bread crumbs, and dried parsley. Mix well.
Dredge each chicken breast in the flour mixture, making sure it's fully coated. Shake off any excess flour.
Dip the floured chicken breast into the beaten eggs, ensuring it's completely coated. Let the excess egg drip off.
Dredge the chicken breast in the parmesan cheese mixture, pressing gently to adhere the coating. Make sure every nook and cranny is covered!
In a large skillet, heat the olive oil and butter over medium heat until the butter is melted and the oil is shimmering.
Carefully place the breaded chicken breasts into the hot skillet, being careful not to overcrowd the pan. You may need to cook them in batches.
Cook for about 5-7 minutes per side, or until the chicken is golden brown and cooked through. The internal temperature should reach 165°F (74°C).
Remove the cooked chicken breasts from the skillet and place them on a wire rack to drain excess oil.
In the same skillet (wipe it out if needed), melt the butter over medium heat.
Add the minced garlic and sauté for about 1-2 minutes, or until fragrant. Be careful not to burn the garlic!
Pour in the chicken broth and bring to a simmer, scraping up any browned bits from the bottom of the skillet.
Reduce the heat to low and stir in the heavy cream, grated parmesan cheese, and dried Italian herbs.
Season with salt and pepper to taste.
Simmer for about 3-5 minutes, or until the sauce has thickened slightly.
Serve the crispy parmesan chicken drizzled with the rich garlic sauce.
