Chicken alfredo usually means two pots, a colander, and a cream sauce that breaks if you look at it wrong. This version cooks the pasta directly in the sauce — milk, broth, butter, garlic — so it absorbs flavor the whole time and comes out with a clingy, starchy coating that a separate pot of boiled pasta can’t match.
It’s done in about 30 minutes and there’s one pot to wash. The parmesan goes in at the end, off the heat, so it melts into the sauce without clumping. If the sauce tightens up while you’re plating, splash in a little pasta water or milk.
How to Make One Pot Chicken Alfredo
Step 1
Season the chicken with salt and pepper. Heat olive oil in a large deep skillet or Dutch oven over medium-high heat. Sear the chicken 5 minutes per side until golden. Remove and let rest. 
Step 2
Reduce heat to medium. Add butter and garlic, cook 30 seconds until fragrant.
Pour in the broth and milk. Add the fettuccine and stir to separate the noodles. Bring to a boil, then reduce to a strong simmer.
Step 3
Cook, stirring frequently, for 12 to 14 minutes until the pasta is al dente and has absorbed most of the liquid.
Step 4
Slice the rested chicken into strips. Reduce heat to low. Stir in the cream, Parmesan, nutmeg, salt, and pepper. Stir until the sauce is creamy and coats the pasta.
Nestle the sliced chicken into the pasta. Garnish with parsley and serve straight from the pot.
One-Pot Chicken Alfredo
- Total Time: 30 minutes
- Yield: 4 servings 1x
Description
One-pot chicken Alfredo is the weeknight answer to the question nobody asked but everybody thought: can I get restaurant-quality Alfredo without dirtying every pot in the kitchen? Yes. The pasta cooks right in the sauce, the chicken sears in the same pot, and the whole thing comes together in under 30 minutes with one pot to wash.
Ingredients
- 1 1/2 lbs boneless, skinless chicken breasts
- 1 tablespoon olive oil
- 4 tablespoons unsalted butter
- 4 cloves garlic, minced
- 3 cups chicken broth
- 2 cups whole milk
- 1 lb fettuccine, broken in half
- 1 cup heavy cream
- 1 1/2 cups freshly grated Parmesan
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1/4 teaspoon freshly grated nutmeg
- 2 tablespoons fresh parsley, chopped
Instructions
- Season the chicken with salt and pepper. Heat olive oil in a large deep skillet or Dutch oven over medium-high heat. Sear the chicken 5 minutes per side until golden. Remove and let rest.
- Reduce heat to medium. Add butter and garlic, cook 30 seconds until fragrant.
- Pour in the broth and milk. Add the fettuccine and stir to separate the noodles. Bring to a boil, then reduce to a strong simmer.
- Cook, stirring frequently, for 12 to 14 minutes until the pasta is al dente and has absorbed most of the liquid.
- Slice the rested chicken into strips. Reduce heat to low. Stir in the cream, Parmesan, nutmeg, salt, and pepper. Stir until the sauce is creamy and coats the pasta.
- Nestle the sliced chicken into the pasta. Garnish with parsley and serve straight from the pot.
Notes
- Stir the pasta frequently as it cooks — one-pot pasta methods are prone to sticking and uneven cooking without regular attention.
- Breaking the fettuccine in half is not sacrilege here — it is practical. Full-length noodles clump in a one-pot setup.
- Use freshly grated Parmesan, not the stuff from the green can. Pre-grated cheese contains anti-caking agents that prevent smooth melting.

Frequently Asked Questions
Can I use a different type of pasta instead of fettuccine?
Yes, you can use other pasta shapes like penne or rotini, but cooking times may vary slightly, so check for doneness as you simmer.
What can I substitute for chicken if I want a vegetarian version?
You can replace the chicken with sautéed mushrooms or a plant-based protein, ensuring to adjust cooking times accordingly.
How do I prevent the cream from clumping when adding it to the sauce?
Make sure to add the cream off the heat and stir it in gently until it’s fully incorporated for a smooth sauce.
Made this last night and liked the one-pot approach a lot. The pasta soaking up the broth and cream while it cooks makes the sauce come together without needing a separate pan. I did add a little extra Parmesan at the end but otherwise followed the recipe exactly.
Quick question — would this work with rotisserie chicken instead of cooking the chicken in the pan first?
Yes, that works well. Since rotisserie chicken is already cooked, add it closer to the end, once the pasta is almost done. That way it just warms through and doesn’t dry out.
