This creamy lemon chicken fettuccine with asparagus is a bright, rich pasta dinner that comes together in about 45 minutes. Juicy seared chicken, crisp-tender asparagus, and ribbons of fettuccine are tossed in a garlicky lemon cream sauce finished with plenty of Parmesan.
The sauce is the star. Butter, garlic, and heavy cream simmer into a silky base, and the lemon goes in at the very end, off the heat, so the sauce stays smooth instead of splitting. If you prefer a lighter lemon pasta without cream, my quick lemon garlic chicken pasta is the dairy-light option, and this one is for nights when you want something cozy and a little indulgent.

Why This Works
- Lemon goes in last. Acid can make hot cream separate. Adding the juice and zest after the pan comes off the heat keeps the sauce silky.
- Asparagus cooks with the pasta. Dropping it into the pot for the last few minutes saves a pan and keeps it crisp-tender.
- Pasta water is the secret. The starchy water loosens the sauce and helps it cling to the noodles.
- The sauce is measured. One and a quarter cups of cream is enough to coat twelve ounces of pasta without leaving it heavy or swimming.
Ingredients
- 12 oz fettuccine
- 2 large boneless, skinless chicken breasts (about 1 1/4 lb total)
- 1 tablespoon olive oil
- 1 lb asparagus, woody ends trimmed, cut into 2-inch pieces
- 3 tablespoons butter
- 4 cloves garlic, minced
- 1 1/4 cups heavy cream
- 3/4 cup freshly grated Parmesan cheese
- Zest of 1 lemon
- 3 tablespoons fresh lemon juice
- 1/2 cup reserved pasta water
- Salt, pepper, and chopped parsley
How to Make Creamy Lemon Chicken Fettuccine
1. Cook the chicken. Pat the chicken dry and season with salt and pepper. Heat the olive oil in a large skillet over medium-high heat and cook the breasts for about 5 to 7 minutes per side, until golden and 165 degrees F in the center. Rest for 5 minutes, then slice.
2. Boil the pasta. Cook the fettuccine in well-salted water according to the package directions. Add the asparagus for the last 2 to 3 minutes. Scoop out 1/2 cup of pasta water, then drain.
3. Start the sauce. Wipe out the skillet, melt the butter over medium heat, and cook the garlic for 30 seconds until fragrant. Pour in the cream and bring it to a gentle simmer, not a hard boil, for 3 to 4 minutes until slightly thickened.
4. Add the cheese. Whisk in the Parmesan until melted and smooth. Remove the pan from the heat.
5. Finish and toss. Stir in the lemon zest and juice. Add the pasta, asparagus, and a splash of pasta water and toss until coated, adding more water as needed to loosen. Fold in the sliced chicken, taste for salt and pepper, and top with parsley.
How to Serve
Serve straight away in warm bowls with extra Parmesan, black pepper, and lemon wedges. A simple green salad or crusty bread balances the richness. For another creamy lemon option, the creamy lemon garlic shrimp pasta uses a similar sauce. For a cozy soup night, the lemon chicken noodle soup carries the same flavors in a lighter form, and a side of creamy garlic Parmesan orzo fits well on a larger menu.
How to Store and Reheat
Cool the pasta and chicken and refrigerate within two hours of cooking. Texas A&M AgriLife Extension food safety guidance also recommends chilling cooked food within two hours. Keep leftovers in an airtight container for up to 3 days.
Reheat in a skillet over low heat with a splash of milk or cream, stirring gently, until hot. Cream sauces tighten as they cool, so the extra liquid brings back the silky texture. Avoid high heat, which can make the sauce separate.
Tips and Variations
- Use heavy cream. Half-and-half and milk are more likely to curdle with lemon.
- Grill the chicken. A grill or grill pan adds smoky flavor. Cook to 165 degrees F.
- Use rotisserie chicken. Shred or slice about 3 cups of cooked chicken and fold it in at the end.
- Swap the protein. Shrimp works if you cook it briefly and add it at the end.
- Make it lighter. Replace half the cream with pasta water and extra Parmesan. The sauce will be thinner but still lemony.
- Use fresh lemon. Bottled juice tastes flat compared with fresh.
FAQ
Why did my lemon cream sauce split?
Usually the pan was too hot, or the lemon went in while the cream was boiling. Take the pan off the heat before adding it, and whisk in a splash of cold cream or pasta water to bring the sauce back together.
Can I use half-and-half?
It is less stable than heavy cream and more likely to curdle. If you use it, keep the heat low and add the lemon off the heat.
Can I make this ahead?
The chicken can be cooked a day ahead. The sauce is best made fresh, because cream sauces thicken and separate when reheated.
What pasta shapes work?
Fettuccine is traditional, but linguine, spaghetti, or penne all work. Choose a shape that holds sauce well.
Can I add other vegetables?
Peas, spinach, or broccoli florets are good additions. Add them with the asparagus in the last minutes of boiling.
