Prep Before Cooking Here’s the thing: simple dishes taste better when the prep feels calm. Bring a big pot of salted water to a boil. The water should taste almost like ocean water — it’s the foundation of good pasta. Slice chicken into strips or bite-sized pieces. Season generously with salt and black pepper. A little paprika works too if you want color.

Cook the Pasta Drop the fettuccine into boiling water and cook until al dente — not mushy, not stiff, just a slight bite. Remember: Save 1 cup of pasta water before draining. This trick rescues sauces more often than you’d expect.

Sear the Chicken Heat a skillet with olive oil over medium-high. Cook chicken 4–6 minutes per side until golden and cooked through. When you press it lightly, it should feel firm but juicy — not dry or rubbery. Set aside and keep warm. The browned bits left in the pan? Those are flavor gold. They’ll mix right into the sauce.

Build the Alfredo Sauce This is where the comfort starts. In the same skillet, melt butter and cook garlic about 60 seconds. You’ll smell it instantly. Pour in cream or half-and-half and let it bubble gently — not a rapid boil. Let it thicken for about 5–8 minutes. Stir in freshly grated Parmesan until smooth. Taste and season again with salt and pepper. If it feels too thin, don’t panic — a splash of pasta water or extra cheese usually solves it. If it thickens too much, a splash of milk brings it back.

Combine & Serve Add pasta and chicken to the skillet, tossing until every ribbon of fettuccine glistens. Let everything rest for a minute. Pasta absorbs sauce like a sponge when it’s warm. Finish with chopped parsley and more Parmesan. There’s always room for more Parmesan.
