Start by heating the olive oil in a large sauté pan over medium heat. Once it shimmers, add the sliced chicken cutlets and cook until they are golden brown and just cooked through. Keep an eye on them to avoid drying out.
Remove the chicken and toss in the butter with chopped onions. Sauté the onions until they soften and become translucent, stirring regularly to avoid burning.
Stir in the minced garlic, oregano, smoked paprika, garlic powder, onion powder, salt, and black pepper. Cook for a couple of minutes until the garlic is fragrant, being careful not to let it brown.
Combine the heavy cream and chicken broth, stirring everything together until it bubbles gently. The sauce should coat the back of a spoon; do not let it boil too vigorously to prevent separation.
While the sauce simmers, cook your chosen pasta in a stockpot until al dente. After draining, toss with a little olive oil to prevent sticking.
Add the cooked pasta, chicken, lemon zest, lemon juice, parsley, and Parmigiano Reggiano cheese to the sauce. Gently toss until everything is well coated and heated through, ensuring the pasta remains intact.
Transfer the lemon chicken pasta to serving plates and sprinkle with extra parsley and cheese for garnish. This adds a pop of color and freshness to the dish.
