Creamy Chicken Penne with Garlic Butter in Cream Cheese Sauce

Sometimes the best dinners come together from what’s already in the fridge, and Creamy Chicken Penne with Garlic Butter in Cream Cheese Sauce is exactly that kind of recipe. Using cooked chicken — whether grilled, rotisserie, or leftovers from another meal — this dish transforms simple ingredients into a rich, ultra-smooth pasta dinner in well under 30 minutes. Penne is tossed with a garlic butter cream cheese sauce and warmed through with tender chicken, creating a satisfying meal that’s as convenient as it is comforting.

What makes this recipe especially practical is its reliance on already-cooked chicken, which eliminates a significant chunk of both prep time and cleanup. The sauce itself is where the real flavor magic happens: butter and garlic form the aromatic base, softened cream cheese melts in for that signature velvety, tangy richness, and Parmesan rounds everything out with salty, nutty depth. It’s a genuinely simple formula that delivers a sauce far more luxurious than the short ingredient list might suggest.

In this article, we’ll walk through a complete ingredient breakdown, detailed step-by-step instructions, expert tips for the smoothest possible sauce, creative variation ideas, storage and reheating instructions, and answers to the most frequently asked questions about this recipe.

Why This Recipe Works So Well

Using pre-cooked chicken as the protein base is a smart shortcut that plenty of home cooks rely on, and this recipe makes the most of that convenience:

It’s an excellent way to use up rotisserie or leftover chicken. Rather than needing to season and cook chicken from scratch, this recipe repurposes chicken you likely already have on hand, cutting down significantly on both time and effort.

Cream cheese creates an incredibly smooth, rich sauce with minimal effort. Unlike building a sauce from multiple shredded cheeses, softened cream cheese melts in quickly and easily, delivering a velvety texture with very little risk of graininess.

The garlic butter base infuses the entire dish with flavor. Sautéing garlic in butter before building the sauce creates that classic, aromatic garlic butter quality that carries through every bite.

It’s genuinely fast. With the chicken already cooked, this recipe comes together in about 20 to 25 minutes, making it one of the quickest options for a rich, satisfying pasta dinner.

It’s a flexible template for using up what you have. The straightforward technique and short ingredient list make this recipe easy to adapt based on whatever chicken, vegetables, or seasonings you have available.

Ingredients You’ll Need

Here’s everything required to make this dish, organized by component.

For the Pasta

• 12 oz penne pasta — its ridges and tubular shape are ideal for holding onto the rich, creamy sauce
• ½ cup reserved pasta water — helps loosen and bind the sauce so it clings evenly to the pasta

For the Chicken

• 2 cups cooked chicken, grilled or rotisserie, diced or shredded — the convenient protein base of this dish; using already-cooked chicken keeps this recipe quick and easy
• Salt, to taste — for seasoning the chicken as it warms in the sauce
• Black pepper, to taste — adds a gentle background heat
• Garlic powder, to taste — reinforces the garlic flavor throughout the dish
• Paprika, to taste — adds warmth and a subtle smoky depth

For the Garlic Cream Cheese Sauce

• 2 tbsp butter — the foundation of the garlic butter flavor that defines this dish
• 3 cloves garlic, minced — the aromatic core of the sauce’s flavor
• 1 cup heavy cream — creates the rich, velvety base of the sauce
• 4 oz cream cheese, softened — adds tanginess and an extra-silky, thick texture to the sauce
• ¾ cup grated Parmesan cheese — adds salty, nutty, umami-rich depth and helps naturally thicken the sauce

Step-by-Step Instructions

Step 1: Cook the Penne

Bring a large pot of well-salted water to a rolling boil. Add the penne and cook according to the package instructions until al dente, usually 9 to 11 minutes.

Before draining, reserve the ½ cup of starchy pasta water needed for the sauce later. Drain the pasta and set it aside.

Step 2: Season the Chicken

While the pasta cooks, place the diced or shredded cooked chicken in a bowl and season to taste with salt, black pepper, garlic powder, and paprika, tossing to coat evenly. Since the chicken is already cooked, this step is primarily about layering in extra flavor before it’s combined with the sauce.

Step 3: Build the Garlic Butter Base

Melt the butter in a large skillet over medium heat. Once melted, add the minced garlic and sauté for about 60 seconds, stirring constantly, until fragrant and lightly golden. Be careful not to let it burn, as this can turn the flavor bitter.

Step 4: Add the Cream

Reduce the heat to medium-low and pour in the heavy cream, stirring well to combine with the garlic butter. Let the cream come to a gentle simmer, being careful not to let it boil too vigorously, as this can cause the dairy to separate.

Step 5: Melt in the Cream Cheese

Add the softened cream cheese to the simmering cream in small chunks, whisking or stirring constantly until it’s fully melted and smooth. Softened cream cheese incorporates far more easily than cold cream cheese, so be sure to let it sit at room temperature for about 20 to 30 minutes before starting this step if you haven’t already.

Step 6: Add the Parmesan

Reduce the heat to low. Add the grated Parmesan gradually, a bit at a time, stirring continuously until fully melted and incorporated into the sauce. This gradual approach helps prevent clumping and ensures a smooth, silky texture.

Step 7: Add the Chicken

Stir the seasoned cooked chicken directly into the sauce, letting it warm through for 2 to 3 minutes over low heat. Since the chicken is already fully cooked, you’re simply looking to heat it through and let it absorb some of the sauce’s flavor.

Step 8: Combine the Pasta and Sauce

Add the drained penne directly into the skillet with the chicken and sauce. Using tongs, gently toss everything together until every piece of pasta and chicken is fully coated in the rich, creamy sauce.

If the sauce seems too thick, add the reserved pasta water a tablespoon at a time, stirring well, until it reaches your desired consistency.

Step 9: Serve

Remove the skillet from heat and serve immediately, garnished with an extra sprinkle of Parmesan and a crack of black pepper, if desired. The sauce will continue to thicken slightly as it cools, so serve right away for the creamiest texture.

Expert Tips for the Best Results

Soften your cream cheese before adding it to the sauce. Cold cream cheese is much harder to incorporate smoothly and can leave lumps in the finished sauce. Letting it sit at room temperature for 20 to 30 minutes beforehand makes a significant difference.

Don’t rush the garlic butter step. Sautéing the garlic in butter until fragrant and lightly golden is what gives this dish its signature flavor. Keep the heat moderate and stir frequently to avoid burning it.

Season the chicken even though it’s already cooked. Since rotisserie or plain grilled chicken can sometimes be mild on its own, taking a moment to season it before adding it to the sauce ensures every bite has plenty of flavor.

Add cheese gradually, not all at once. Stirring in the Parmesan a little at a time, allowing each addition to melt before adding more, is the key to a smooth, lump-free sauce rather than a clumpy one.

Keep the heat low once the cream and cheese go in. High heat can cause a dairy-based sauce to break or turn oily. Medium-low to low heat allows the sauce to come together smoothly.

Reserve your pasta water. This starchy liquid is a useful tool for adjusting the sauce’s consistency without diluting its flavor, so don’t skip scooping some out before draining.

Use freshly grated Parmesan when possible. Pre-shredded cheese is coated with anti-caking agents that can prevent smooth melting. Freshly grated Parmesan will give you the smoothest, creamiest sauce.

Delicious Variations to Try

This recipe is a wonderful base for experimentation. Here are some popular ways to switch things up:

Spicy Version: Add ¼ to ½ teaspoon of red pepper flakes to the sauce for a subtle, warming kick that plays nicely against the richness of the cream cheese.

Veggie-Loaded Version: Stir in baby spinach, sun-dried tomatoes, or sautéed mushrooms during the final simmering step for added nutrition, texture, and color.

Bacon-Garlic Upgrade: Cook a few strips of bacon until crispy, crumble them, and fold them into the finished dish for a smoky, salty crunch.

Broccoli Addition: Blanch a couple cups of broccoli florets in the pasta water during the last few minutes of cooking, then toss them in with the pasta and sauce for added color and nutrition.

Different Pasta Shape: Substitute rotini, farfalle, or rigatoni for the penne if you prefer a different pasta shape — any of these will hold onto the sauce nicely.

Lighter Version: Substitute half-and-half for the heavy cream and reduce the cream cheese slightly to lighten the dish while keeping the core garlic flavor intact.

What to Serve With Creamy Chicken Penne with Garlic Butter in Cream Cheese Sauce

This dish is rich and satisfying enough to be the star of the meal, but a few well-chosen sides can help round out dinner:

• A crisp green salad with a bright, acidic vinaigrette helps cut through the richness of the cream cheese sauce
• Garlic bread or a crusty baguette for those who want even more garlic flavor and something to soak up extra sauce
• Roasted vegetables, such as broccoli, asparagus, or zucchini, add color, fiber, and freshness
• A chilled glass of white wine, like Chardonnay or Pinot Grigio, pairs beautifully with the creamy, garlicky flavors of this dish

Storage and Reheating Instructions

Refrigerating: Store leftovers in an airtight container in the refrigerator for up to 4 days. The sauce will thicken as it chills, which is completely normal.

Freezing: While cream cheese-based sauces can sometimes change texture slightly after freezing, this dish can be frozen for up to 2 months if needed. Thaw overnight in the refrigerator before reheating for best results.

Reheating on the stovetop: Warm leftovers in a skillet over low heat, adding a splash of milk or cream to help restore the sauce’s original silky texture. Stir frequently until heated through.

Reheating in the microwave: Place a portion in a microwave-safe bowl with a splash of milk, cover loosely, and heat in 30-second intervals, stirring between each, until evenly warmed.

Frequently Asked Questions

Can I use rotisserie chicken straight from the store? Yes, rotisserie chicken is an excellent choice for this recipe and saves significant prep time. Simply shred or dice the meat and season it as directed before adding it to the sauce.

Can I use freshly cooked chicken instead of leftovers? Absolutely. If you’d like to cook chicken specifically for this recipe, simply season and pan-sear or grill boneless chicken breasts, then dice or shred once cooked and cooled slightly.

Why did my sauce turn grainy or oily? This usually happens when the heat is too high while melting the cheese, or when cold cream cheese or pre-shredded cheese is used. Keep the heat low, soften your cream cheese beforehand, and use freshly grated Parmesan for the smoothest results.

Can I use a different pasta shape? Yes. While penne’s ridges and tubular shape are great for holding onto the sauce, you can substitute rotini, farfalle, or rigatoni with excellent results.

Can I make this recipe gluten-free? Yes. Substitute your favorite gluten-free penne pasta — all other ingredients in this recipe are naturally gluten-free.

How can I make the sauce even thicker? If you prefer an extra-thick sauce, reduce the amount of reserved pasta water used, or let the sauce simmer for an additional minute or two before adding the pasta, keeping in mind it will continue to thicken as it sits.

How many servings does this recipe make? This recipe typically yields about 4 servings, depending on portion size and appetite.
