Prepare the fries by preheating the oven to 425°F (220°C) and cutting potatoes into fry shapes.
Toss the cut fries in olive oil, salt, and pepper and spread them on a baking sheet.
Bake the fries for 25-30 minutes, flipping halfway through for even cooking.
While the fries are baking, heat olive oil in a large skillet over medium-high heat for the chicken.
Season the chicken fillets with salt and pepper, then sauté in the skillet until golden brown, about 5-7 minutes per side.
Remove the chicken from the skillet and set aside, then reduce the heat to medium.
Add minced garlic and red pepper flakes to the skillet, cooking until fragrant, about 1 minute.
Pour in the heavy cream, stirring to combine, and bring to a simmer for 2-3 minutes.
Stir in the grated Parmesan cheese until melted, creating a creamy sauce.
Return the chicken to the skillet, ensuring it’s coated in the sauce, and allow to heat for 2-3 minutes.
Serve the chicken topped with the sauce alongside the freshly baked fries, garnished with chopped parsley.
