How to Make One Pot Creamy Garlic Penne Pasta Recipe

Step 1: Cook the Pasta

Start by cooking the penne pasta according to the package instructions until it’s al dente, meaning it should be tender but still slightly firm to the bite. Drain it well and set it aside, keeping it warm so it’s ready to soak up all that flavorful sauce later on.

Step 2: Sauté the Garlic in Butter

In a medium saucepan over medium heat, melt the butter gently. Once melted, toss in your minced garlic and cook it for about 1 and a half minutes, stirring constantly to prevent burning. This step releases the garlic’s sweet, fragrant aroma, laying the flavor foundation for your sauce.

Step 3: Make the Roux

Sprinkle the flour into the melted butter and garlic mixture, stirring continuously for another 1 and a half minutes. This forms the roux that will thicken your sauce. Stirring constantly is key here to ensure the flour cooks through and your sauce remains silky smooth without lumps.

Step 4: Add Milk and Chicken Broth

Now comes the transformation—slowly pour in the whole milk and chicken broth while whisking vigorously. Keep whisking until the sauce thickens and just starts to bubble, creating a creamy base that’s irresistible. The gradual addition and whisking prevent lumps and guarantee a glossy sauce consistency.

Step 5: Stir in Parsley and Parmesan

Sprinkle in the parsley flakes for that touch of earthy freshness, then add the freshly grated Parmesan cheese. Stir until the cheese is fully melted and the sauce becomes rich and smooth. Adjust salt and pepper to your liking—this is where you customize the creamy garlic penne to your perfect flavor balance.

Step 6: Combine Pasta and Sauce

Toss your warm penne pasta into the sauce, ensuring each piece is well coated in that creamy, garlicky goodness. If the sauce feels a little too thick, a splash of reserved pasta water will loosen it right up for an ideal sauciness. Serve it piping hot for the best experience!

Side Dishes

This creamy penne pairs wonderfully with crisp green salads or roasted vegetables like asparagus or broccoli for a complete meal that feels balanced and fresh. Garlic bread or a warm baguette also works beautifully to mop up every last bit of that luscious sauce.

Creative Ways to Present

For a fun twist, serve this dish in individual shallow bowls and top with a soft-poached egg or some sautéed mushrooms for added indulgence. If you like, sprinkle toasted pine nuts or crispy pancetta for texture and extra flavor layers. It’s a versatile recipe that’s open to your personal flair.

Make Ahead and Storage

Storing Leftovers

Store any leftover creamy garlic penne pasta in an airtight container in the refrigerator for up to 3 days. The sauce may thicken as it cools, so don’t worry if it looks dense before reheating.

Freezing

While this pasta is best enjoyed fresh, you can freeze leftovers in a freezer-safe container for up to 1 month. Thaw overnight in the fridge before reheating to preserve the sauce’s silky texture.

Reheating

To warm up your leftovers, gently reheat in a saucepan over low heat. Add a splash of milk or broth to loosen the sauce and stir frequently to avoid sticking. Alternatively, microwave in short intervals, stirring each time until heated through and creamy once again.

Can I make this dish dairy-free?

How can I make this pasta gluten-free?

Use gluten-free penne pasta and replace the all-purpose flour with a gluten-free flour blend or cornstarch for thickening. Make sure all other ingredients are labeled gluten-free for safety.
