Start by seasoning the chicken breasts on both sides with salt and pepper. Heat olive oil in a skillet over medium-high heat, then place the chicken in. Cook for about 4–5 minutes per side until golden brown. Don’t worry if it’s not fully cooked yet—it will finish cooking in the sauce.
Remove the chicken and set it aside on a plate. Add butter to the same skillet and let it melt, then toss in the minced garlic. Cook for about a minute, stirring often to avoid burning. At this point, the kitchen will already smell amazing.
Pour in the chicken broth and use a wooden spoon to scrape up the brown bits from the pan. Lower the heat slightly and slowly whisk in the heavy cream. Stir in the grated Parmesan until melted and smooth, forming a luscious sauce.
Return the chicken to the skillet, coating it with the sauce. Let it simmer on low heat for about 10 minutes until the chicken is cooked through and tender. Once ready, sprinkle freshly chopped parsley on top for a pop of freshness and color.
