Cheddar Parmesan Garlic Butter Chicken with Creamy Penne Pasta

There’s a lot to love packed into Cheddar Parmesan Garlic Butter Chicken with Creamy Penne Pasta — bold, Cajun-seasoned chicken bites, a thick and luxurious roux-based cheese sauce built from both cheddar and Parmesan, and a final finishing touch of garlic butter that ties it all together. This isn’t a simple cream sauce tossed together in a few minutes; it’s a proper béchamel-style cheese sauce, giving the dish a thicker, more stable texture that clings beautifully to every piece of penne.

What sets this recipe apart is the roux-based technique used for the cheese sauce. Rather than simply melting cheese into cream, this recipe builds a proper base from butter, garlic, and flour before whisking in whole milk and melting in a generous amount of cheddar and Parmesan. This method creates a thicker, more velvety sauce that holds up beautifully and coats the pasta evenly. Combined with Cajun-seasoned chicken bites and a final drizzle of garlic butter, this dish achieves serious depth and richness in every component.

In this article, we’ll walk through a complete ingredient breakdown, detailed step-by-step instructions, expert tips for building the perfect roux and keeping the chicken flavorful, 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 a proper roux-based cheese sauce sets this dish apart from simpler cream-and-cheese pasta recipes, and this combination brings together several elements that make it especially satisfying:

The roux creates a thicker, more stable sauce. Building the sauce from butter, flour, and milk before adding cheese results in a texture that’s more velvety and less prone to breaking compared to a straight cream-based sauce.

The Cajun-seasoned chicken adds real, bold flavor. Rather than a plain seasoned protein, the chicken carries its own smoky, spicy character that contrasts nicely with the rich, mellow cheese sauce.

Using both cheddar and Parmesan creates real depth. Cheddar brings sharp, tangy flavor while Parmesan contributes salty, nutty complexity, together creating a more interesting sauce than either cheese alone.

The finishing garlic butter adds one more layer of richness. Drizzling additional garlic butter over the finished dish just before serving adds a final, aromatic touch that ties the chicken and pasta together.

It’s a genuinely hearty, satisfying meal. With substantial chicken and a thick, cheese-loaded sauce, this dish delivers serious comfort food satisfaction in every bite.

Ingredients You’ll Need

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

For the Chicken

• 2 large boneless, skinless chicken breasts, cut into 1-inch pieces — the hearty protein base of the dish
• 2 tbsp olive oil — used to help sear the chicken
• 2 tbsp garlic butter — adds rich, garlicky flavor as the chicken finishes cooking
• 2 tsp Cajun seasoning — the primary seasoning that gives the chicken its bold, smoky heat
• 1 tsp paprika — reinforces the warm, smoky depth of the seasoning
• Salt and black pepper to taste — essential for properly seasoning the chicken

For the Pasta

• 1 lb penne pasta — its ridges and tubular shape are ideal for holding onto the thick, cheesy sauce

For the Cheddar Parmesan Sauce

• 6 tbsp butter — the rich base for the roux that thickens the sauce
• 4 garlic cloves, minced — adds essential aromatic depth
• 4 tbsp all-purpose flour — combined with butter to create the roux that gives this sauce its thick, velvety texture
• 4 cups whole milk — forms the body of the sauce once thickened by the roux
• 2 cups shredded cheddar cheese — adds sharp, savory flavor and a beautiful golden color
• 1 cup grated Parmesan — adds salty, nutty, umami-rich complexity
• ½ tsp salt — essential for properly seasoning the sauce
• ¼ tsp black pepper — adds a gentle background heat
• ¼ tsp garlic powder — reinforces the garlic flavor throughout the sauce
• ¼ tsp onion powder — adds aromatic depth

To Finish

• 2 tbsp garlic butter — drizzled over the finished dish for a final layer of rich, garlicky flavor

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. Drain the pasta and set it aside.

Step 2: Season and Sear the Chicken

Pat the chicken pieces dry with paper towels to help them sear properly. In a bowl, toss the chicken with the Cajun seasoning, paprika, salt, and black pepper until evenly coated.

Heat the olive oil in a large skillet over medium-high heat. Once hot, add the seasoned chicken in a single layer, working in batches if necessary to avoid overcrowding the pan. Sear for 5 to 7 minutes, stirring occasionally, until deeply golden brown on the outside and cooked through to an internal temperature of 165°F (74°C).

In the final minute of cooking, add the 2 tablespoons of garlic butter to the skillet, stirring to coat the chicken evenly as it melts. Remove the chicken from the skillet and set it aside on a plate.

Step 3: Build the Roux

In the same skillet (or a separate large saucepan, if you’d like to keep the flavorful bits from the chicken in a dedicated pan), melt the 6 tablespoons of butter over medium heat. Add the minced garlic and sauté for about 30 to 60 seconds, until fragrant.

Sprinkle the flour evenly over the melted butter and garlic, whisking constantly to combine. Cook this roux for 1 to 2 minutes, stirring frequently, until it looks pale golden and slightly bubbly. This step is essential for cooking off the raw flour taste and creating the base that will thicken your sauce.

Step 4: Add the Milk

Slowly pour in the whole milk while whisking constantly to prevent lumps from forming. Add it gradually at first, whisking until smooth, before adding the rest more quickly. Continue whisking over medium heat until the mixture thickens and coats the back of a spoon, about 5 to 7 minutes.

Step 5: Melt in the Cheese

Reduce the heat to low. Add the shredded cheddar cheese gradually, a handful at a time, whisking continuously until fully melted before adding more. Once the cheddar is fully incorporated, repeat the same gradual process with the grated Parmesan. Adding the cheeses slowly and in stages is essential for a smooth, lump-free sauce.

Stir in the salt, black pepper, garlic powder, and onion powder, tasting and adjusting the seasoning as needed.

Step 6: Combine the Pasta and Sauce

Add the drained penne directly into the sauce, stirring gently until every piece of pasta is fully coated in the thick, cheesy sauce.

Step 7: Add the Chicken and Finish with Garlic Butter

Stir the seared, garlic butter-coated chicken back into the pasta and sauce, combining everything together. Drizzle the final 2 tablespoons of garlic butter over the top just before serving, letting it melt slightly into the dish.

Step 8: Serve

Serve immediately while hot, garnished with an extra sprinkle of Parmesan or fresh parsley, if desired.

Expert Tips for the Best Results

Cook the roux fully before adding the milk. Taking the full 1 to 2 minutes to cook the butter and flour together is essential for eliminating any raw flour taste in the finished sauce.

Whisk constantly when adding the milk. Adding it gradually while whisking prevents lumps from forming and ensures a smooth, velvety sauce.

Add the cheese gradually, off high heat. Building the sauce in stages — melting the cheddar fully before adding the Parmesan — is essential for achieving a smooth, cohesive texture rather than a clumpy or stringy one.

Don’t overcrowd the pan when searing chicken. Searing in batches, if necessary, ensures each piece develops a proper golden crust instead of steaming from being too close together.

Use good-quality garlic butter, or make your own. Since garlic butter is used twice in this recipe — once with the chicken and once as a finishing touch — using a flavorful, well-seasoned garlic butter (store-bought or homemade from softened butter, minced garlic, and a pinch of salt) makes a real difference.

Use freshly shredded cheddar and grated Parmesan when possible. Pre-shredded cheeses are coated with anti-caking agents that can affect melting texture, especially in a roux-based sauce where smoothness is key.

Serve promptly for the best texture. This sauce is at its silkiest right after cooking, so serve it soon after combining everything for the creamiest result.

Delicious Variations to Try

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

Extra Spicy Version: Increase the Cajun seasoning on the chicken, or add a pinch of cayenne to the sauce, for a bolder, spicier kick throughout.

Veggie-Loaded Version: Stir in steamed broccoli florets or sautéed bell peppers when combining the pasta and sauce for added color, texture, and nutrition.

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

Different Cheese Blend: Substitute Monterey Jack or a smoked gouda for part of the cheddar for a different flavor profile.

Blackened Chicken Style: For an even deeper flavor, let the seasoned chicken develop a darker, more blackened crust by searing it a bit longer over slightly higher heat.

Lighter Version: Substitute 2% milk for the whole milk and reduce the total cheese slightly to lighten the sauce while keeping the core flavors intact.

What to Serve With Cheddar Parmesan Garlic Butter Chicken and Creamy Penne Pasta

This dish is rich and hearty 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 cheese sauce and balance the spice
• Garlic bread or a crusty baguette for those who want something to soak up any extra sauce
• Roasted or steamed vegetables, such as broccoli, green beans, or asparagus, add color, fiber, and freshness
• A chilled glass of white wine, like Chardonnay or Sauvignon Blanc, pairs beautifully with the creamy, cheesy 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 further as it chills, which is completely normal for a roux-based sauce.

Freezing: Roux-based cheese sauces can sometimes change texture slightly after freezing, but this dish can still 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 to help restore the sauce’s original 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 a different pasta shape? Yes. While penne’s ridges and tubular shape are great for holding onto this thick sauce, you can substitute rigatoni, rotini, or farfalle with excellent results.

Can I make my own garlic butter instead of buying it? Yes. Simply combine softened butter with 2 to 3 cloves of minced garlic and a pinch of salt, mixing well. This can be made ahead and stored in the refrigerator until needed.

Why is my sauce lumpy? This is usually caused by adding the milk too quickly or not whisking constantly while it’s incorporated into the roux. Adding it gradually while whisking continuously helps prevent this issue.

Can I use chicken thighs instead of chicken breast? Yes, boneless, skinless chicken thighs work wonderfully in this recipe and tend to stay even juicier than chicken breast.

Can I make this recipe gluten-free? Yes. Substitute your favorite gluten-free penne pasta, and replace the all-purpose flour in the sauce with an equal amount of a gluten-free flour blend or cornstarch (using about half the amount for cornstarch, since it thickens more efficiently).

Why did my sauce turn out too thick or too thin? If too thick, thin it with a splash of extra milk, a tablespoon at a time. If too thin, let the sauce simmer a bit longer over low heat, allowing more liquid to evaporate and thicken naturally.

How many servings does this recipe make? This recipe typically yields about 6 servings, depending on portion size and appetite.
