30-Minute Creamy Chicken Alfredo Penne

Creamy chicken alfredo penne packs all the richness of a restaurant dish into a dinner that is fast enough for a Tuesday night.

The sauce is made from scratch with butter, garlic, heavy cream, and Parmesan. No roux, no fuss, just a velvety coating that clings to every ridged tube.

Why This Alfredo Works

I keep this recipe around because it tastes luxurious without needing a lot of attention. The sauce comes together in one skillet while the pasta boils, so there is no juggling.

Penne is the right shape here. The ridges and hollow centers trap the creamy sauce, so every bite is evenly coated. Freshly grated Parmesan melts into the cream without turning grainy, giving you that silky finish.

Ingredients

• 12 oz penne pasta: any short tube shape works, like rigatoni or ziti
• 1 lb boneless skinless chicken breasts (about 2): or boneless thighs for extra juiciness
• 3 tbsp unsalted butter: divided
• 4 cloves garlic, minced: fresh garlic, not jarred, for a clean taste
• 1 1/2 cups heavy cream: labeled heavy whipping cream
• 1 1/2 cups freshly grated Parmesan cheese: avoid pre-shredded, it will not melt smoothly
• 1/2 tsp salt: plus more for the pasta water
• 1/4 tsp black pepper: freshly ground is best
• 2 tbsp chopped fresh parsley: optional, for a pop of green

Variations / Substitutions

• Protein swap: use grilled shrimp, sliced cooked sausage, or leftover rotisserie chicken. Add them right after the sauce is done.
• Different pasta: any short shape like rigatoni, fusilli, or farfalle works. Long pasta like fettuccine is classic, but penne holds more sauce.
• Lighter option: substitute half-and-half for the heavy cream, but keep the heat low and do not boil or the sauce may separate.
• Add a kick: a pinch of red pepper flakes in the butter before the garlic adds gentle heat. A squeeze of lemon at the end brightens everything.
• Greens: stir in a handful of baby spinach or thawed frozen peas during the last minute of sauce cooking for extra color.

How to Make Chicken Alfredo Penne

Step 1: Boil the Pasta

Bring a large pot of salted water to a boil. Cook the 12 oz penne according to package directions until al dente, about 10 to 12 minutes. Just before draining, scoop out 1 cup of the starchy pasta water and set it aside.

The water should be salty like the sea. That seasoning penetrates the pasta itself, and the reserved starchy water will loosen the sauce later if needed.

Step 2: Sear the Chicken

While the pasta cooks, pat the 1 lb chicken breasts dry. Season both sides with the 1/2 tsp salt and 1/4 tsp pepper. Heat 1 tbsp of the butter in a large skillet over medium-high. Once melted and foaming, add the chicken in a single layer. Cook for 5 to 6 minutes per side, until deeply golden and an instant-read thermometer inserted in the thickest part reads 165°F (74°C). Transfer the chicken to a cutting board and tent loosely with foil.

The browned bits left in the skillet carry concentrated chicken flavor and will season the sauce. Letting the chicken rest while you build the sauce keeps the juices inside the meat.

Step 3: Build the Alfredo Sauce

In the same skillet, reduce the heat to medium. Add the remaining 2 tbsp butter and let it melt, scraping up any browned bits from the bottom. Add the 4 cloves minced garlic and cook, stirring constantly, until fragrant, about 30 seconds. Do not let it brown. Pour in the 1 1/2 cups heavy cream and bring the mixture to a gentle simmer. Reduce the heat to low, then whisk in the 1 1/2 cups freshly grated Parmesan a handful at a time until fully melted and the sauce is smooth, about 2 to 3 minutes. If the sauce seems too thick, stir in a splash of the reserved pasta water.

The sauce should coat the back of a spoon without being gloppy. Taste and add more salt or pepper if needed, remembering the Parmesan brings plenty of salt.

Step 4: Toss and Serve

Slice the rested chicken against the grain into strips. Add the drained penne to the skillet with the sauce and toss until every piece is coated. Fold in the sliced chicken, then divide among bowls. Sprinkle with the 2 tbsp chopped parsley and serve right away, while the sauce is glossy and the chicken tender.

Tips for the Best Alfredo Sauce

• If your cream sauce looks greasy or separated, remove it from the heat and whisk in a splash of cold cream or a pat of cold butter. The emulsion will come back together.
• For the cleanest slices, let the cooked chicken rest not only while you make the sauce, but also cool slightly so it firms up. Then cut against the grain.
• Parmigiano-Reggiano gives the deepest nutty flavor, but grana padano is a good budget substitute that still melts smoothly.

Cook times for chicken by thickness:

Storing Leftover Alfredo Pasta

• Refrigerate: Keep leftovers in an airtight container in the fridge for up to 3 days. The sauce will thicken as it chills, so plan to add a splash of milk when reheating.
• Reheating: Warm gently in a skillet over low heat or in the microwave in 30-second bursts, stirring in a tablespoon or two of milk or cream to loosen the sauce. Avoid high heat, which can cause the cream to separate.

What to Serve With Chicken Alfredo Penne

A simple arugula salad with lemon vinaigrette cuts through the richness with acidity and pepperiness. Garlic bread is always welcome for mopping up extra sauce. Roasted broccoli or asparagus on the side adds a fresh vegetable and a little crunch.

Frequently Asked Questions

How do I keep the sauce from breaking?

Keep the heat low once you add the cream, and add the Parmesan off the heat or over very low heat, whisking constantly. High heat can cause the dairy to separate.

Can I add vegetables?

Absolutely. Stir in steamed broccoli florets, sautéed mushrooms, or a handful of baby spinach at the end. They meld right into the creamy sauce.

Is this gluten-free?

The sauce itself is naturally gluten-free. Use gluten-free penne and double-check that your Parmesan is certified gluten-free (most are).

Can I double the recipe?

Yes, use a larger skillet or sear the chicken in batches. Increase the sauce ingredients proportionally, but you may not need to fully double the heavy cream if you prefer a lighter coating.

• 2 tbsp chopped fresh parsley (optional)

Method

 

1. Boil a large pot of salted water and cook penne al dente. Reserve 1 cup pasta water before draining.
2. Season chicken with salt and pepper. Melt 1 tbsp butter in a skillet over medium-high. Sear chicken 5 to 6 minutes per side until golden and 165°F (74°C). Remove and rest.

4. Slice chicken. Toss drained penne in the sauce, fold in chicken, and serve with parsley.

Notes

Let the chicken rest at least 5 minutes before slicing. If the sauce thickens too much after adding the pasta, stir in a splash of reserved pasta water until it reaches the consistency you like.
