Season chicken cutlets evenly with salt, pepper, and garlic powder.
Dredge each cutlet in all-purpose flour, shaking off excess to ensure a light coating.
Heat olive oil and 1 tablespoon of butter in a large skillet over medium-high heat.
Sear chicken for 4 to 5 minutes per side until golden brown and the internal temperature reaches 165 degrees Fahrenheit. Remove chicken from skillet and set aside.
In the same skillet, melt the remaining butter and sauté minced garlic for 60 seconds until fragrant.
Deglaze the skillet with chicken broth, scraping the bottom to incorporate fond.
Whisk in heavy cream, dried oregano, and parmesan cheese. Simmer for 3 to 5 minutes until the sauce achieves a nappe consistency.
Stir in fresh lemon juice and chopped parsley.
Return the chicken cutlets to the skillet, spooning the sauce over the surface, and serve immediately.
