I start by filling a large pot with water and adding a generous pinch of salt, then bringing it to a rolling boil. Getting this going early means the pasta will be ready right when my sauce and chicken finish cooking. Salting the water well is what actually seasons the noodles from the inside.
I lay out three shallow dishes: one with flour, one with whisked eggs, and one with panko mixed with parmesan cheese. Keeping these separate and in order makes breading the chicken quick and mess-free. This little bit of prep saves me from scrambling later.
I mix garlic powder, onion powder, and Italian seasoning together, then rub it over both sides of the chicken along with a light sprinkle of salt and pepper. Next, I dredge each piece in flour, dip it in egg, and press it firmly into the panko mixture. This three-step coating is what gives the chicken its shatter-crisp crust.
While I fry the chicken, I drop the fettuccine into the boiling water and cook it according to the package instructions until al dente. I always reserve a small cup of that starchy pasta water before draining, since it's my secret weapon for a silkier sauce later.
In a separate skillet, I melt the butter and toss in the minced garlic, letting it cook for about 30 seconds until fragrant. Then I pour in the heavy cream and parmesan, whisking frequently for 6-8 minutes until the sauce thickens. I finish it with a generous pinch of salt and pepper.
I heat oil in a large skillet over medium-high heat and fry the breaded chicken for 2-3 minutes per side until golden and crunchy. Once it's done, I slice each cutlet into bite-sized strips so it's easier to serve over the pasta.
I toss the cooked fettuccine directly into the alfredo sauce, adding the reserved pasta water to loosen everything into a creamy, glossy coat. Then I lay the crispy chicken pieces right on top and dig in while it's still hot.
