For the Chicken Alfredo
- Chicken Breast – Boneless, skinless chicken breasts work perfectly. Slice them thinly for even cooking and juicy bites.
- Fettuccine Pasta – Classic for Alfredo! You can also use angel hair or vermicelli for a lighter twist.
- White Mushrooms – Add a meaty texture and earthy flavor to balance the creamy sauce.
- Onion – Finely chopped to melt into the sauce and add a subtle sweetness.
- Garlic – Freshly minced for that irresistible, aromatic base.
- Half and Half – Creates a rich, silky sauce without feeling too heavy. (See note below for easy substitutes.)
- Parsley – Adds freshness and a pop of color; stir some into the sauce and save a little for garnish.
- Sea Salt & Black Pepper – Essential for seasoning both the chicken and the sauce.
- Olive Oil – Used to sauté the chicken and vegetables for extra depth of flavor.
- Unsalted Butter – Blends with olive oil for a richer sauté and a touch of indulgence.
Ingredient Notes
- Substitute for Half and Half – Mix equal parts milk and heavy cream, or use all heavy cream for a thicker, richer sauce.
- Mushroom Lovers Tip – Swap white mushrooms for cremini or baby bella mushrooms for deeper flavor.
- Make It Creamier – Add a handful of grated Parmesan at the end for restaurant-style texture.

Ingredients
Protein & Pasta
- 2 lbs chicken breast
- ¾ lb fettuccine pasta (or substitute angel hair or vermicelli)
- 1 lb white mushrooms, thickly sliced
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 3 ½ cups half and half (see note for substitution)
- ¼ cup fresh parsley, finely chopped, plus more for garnish
- 1 tsp sea salt, or to taste, plus more for pasta water
- ¼ tsp black pepper, or to taste
- 3 Tbsp olive oil, divided
- 1 Tbsp unsalted butter
-
Cook the Pasta:
Bring 4 quarts of salted water (1 Tbsp salt) to a boil. Cook fettuccine according to package directions until al dente. Drain and set aside. -
Cook the Chicken:
Slice chicken into thin strips and season with salt and pepper.
In a large skillet, heat 2 Tbsp olive oil over medium-high heat.
Sauté chicken until golden and fully cooked (about 5 minutes).
Remove from the pan and cover to keep warm. -
Sauté the Vegetables:
In the same skillet, heat 1 Tbsp olive oil and 1 Tbsp butter over medium-high heat.
Add the chopped onion and cook for 3 minutes until soft.
Stir in mushrooms and cook until tender, 5–7 minutes, stirring often.
Add minced garlic and cook for 30 seconds, stirring constantly. -
Make the Sauce:
Pour in the half and half and bring to a gentle simmer.
Cook for 8–10 minutes, or until the sauce begins to thicken slightly. -
Combine Everything:
Return chicken to the pan.
Stir in ¼ cup parsley and season to taste with additional salt and pepper (½–1 tsp salt, ¼ tsp pepper).
Add cooked pasta and toss to coat evenly.
Heat for another minute until warmed through. -
Finish & Serve:
Turn off the heat, cover, and let rest for 10–15 minutes to allow the sauce to thicken.
Stir again before serving and garnish with extra parsley.
- Half and Half Substitute: Use equal parts milk and heavy cream.
- For a richer, thicker sauce, use heavy whipping cream instead of half and half.
- My sauce split or turned grainy—what did I do wrong?
Don’t worry, it happens to the best of us! Alfredo sauce can separate if the heat’s too high or if dairy’s added too quickly. Keep your pan on a gentle simmer (never a boil), and whisk as you go. If it does split, just stir in a splash of warm pasta water and it’ll come back together beautifully.
- Can I make any part of this ahead of time?
Absolutely! You can cook the chicken and prep the sauce in advance—just store them separately from the pasta. When you’re ready to eat, gently reheat everything together with a splash of milk or cream. Dinner on the table in minutes!
- How do I keep the sauce creamy and not dry once I add the pasta?
The secret weapon: pasta water. Always save a cup before draining! The starchy water helps the sauce cling perfectly to your noodles. Stir well, add a splash if it feels too thick, and watch that silky magic happen.
- I don’t have half-and-half. What can I use instead?
No problem. Mix equal parts milk and heavy cream for the same luscious result. In a pinch, even all milk will work—just expect a lighter, thinner sauce. (And maybe sneak in an extra knob of butter… you deserve it.)
- How should I reheat leftovers so they stay creamy?
Gently is the key word! Warm it over low heat on the stove with a little extra milk or cream. Stir as it heats up to keep everything smooth. If you’re using the microwave, do short bursts and stir in between—no dry chicken or clumpy sauce on our watch.
