Prepare the Chicken Coating: In one dish, mix oat flour with salt, pepper, garlic powder, and oregano. In another, beat the eggs. In a third, add crushed cornflakes or panko.
Coat the Chicken: Dip each chicken breast in the flour mixture, then egg, then press into cornflakes or panko until fully coated.
Cook the Chicken: Heat olive oil in a skillet over medium heat. Cook chicken for 4–5 minutes per side until golden brown and fully cooked. Remove and set aside.
Cook the Pasta: Bring a pot of salted water to a boil and cook pasta until al dente. Reserve some pasta water, then drain.
Make the Sauce: In the same skillet, heat olive oil and sauté garlic for about 1 minute. Add pasta sauce and bring to a gentle simmer. Stir in cream cheese until smooth, then add Parmesan, lemon juice, and zest. Add pasta water as needed to loosen the sauce. Season to taste.
Combine Pasta & Sauce: Toss cooked pasta with the sauce until evenly coated.
Assemble & Serve: Slice the chicken and place over the pasta. Garnish with parsley and extra Parmesan if desired.
