If you're using frozen fries, follow the package instructions for optimal crispiness. For homemade fries, preheat your oven to 425°F (220°C). Cut potatoes into even strips, toss them in a bowl with olive oil, salt, and pepper until well-coated. Place the fries on a baking sheet in a single layer and bake for 30-35 minutes, flipping halfway, until golden and crispy.

Heat a tablespoon of olive oil in a large skillet over medium heat until shimmering. Season your chicken fillets generously with salt and pepper. Sear the fillets for 6-7 minutes on each side until they achieve a beautiful golden brown color and the internal temperature reads 165°F (74°C). Once cooked, remove the chicken from the skillet and set aside to rest.

In the same skillet where you cooked the chicken, add a bit more olive oil if needed and sauté minced garlic for about 1 minute until fragrant and lightly golden. Next, pour in the heavy cream, stirring gently as it begins to simmer. Let it cook for 2-3 minutes to thicken slightly before adding the grated Parmesan cheese and red pepper flakes, stirring until smooth.

Return the cooked chicken fillets to the skillet, ensuring they are generously coated in the spicy, creamy garlic-Parmesan sauce. Allow the mixture to simmer for an additional 2-3 minutes so the flavors meld together beautifully. Keep an eye on the sauce's consistency; if it becomes too thick, add a splash of cream for a silkier texture.

Once everything is perfectly combined, plate the crispy fries alongside the chicken fillets. Drizzle the luscious sauce generously over the chicken, letting it cascade beautifully. For an optional touch, garnish with freshly chopped parsley to add a pop of color. Prepare to dig into your delightful Chicken Fillet in Spicy, Creamy Garlic-Parmesan Sauce!
