• 300 g penne pasta (cooked al dente): The perfect pasta shape to hold the creamy pesto sauce in every nook.

• 6 tbsp pesto sauce: The star ingredient with its herby punch and garlicky kick.
• 1/2 cup reserved pasta water: Helps loosen the sauce while adding a bit of starch for creaminess.
• 2 cups heavy cream (35%): Creates that irresistible luscious and smooth base.
• 1 1/2 tbsp all-purpose flour: Thickens the sauce to a perfect consistency without lumps.
• 1 tbsp garlic powder: Boosts the savory flavor and complements the pesto.
• 1 tbsp dried oregano: Adds a warm, earthy note that rounds out the herb profile.
• Freshly chopped parsley (a handful): Brings a fresh, vibrant finish to the dish.

• Grated Parmesan for topping (optional): A salty, nutty garnish to elevate every forkful.

How to Make Creamy Pesto Sauce Pasta (Best Easy One Pot Recipe)

Step 1: Sauté the Vegetables

Start by heating a large pan over medium heat and toss in your diced green bell pepper and red onion with a sprinkle of salt. Sauté these until they soften and turn slightly caramelized, about 10 minutes. This slow cooking draws out their natural sweetness and builds a flavorful foundation for the creamy sauce ahead. Take your time here—it really makes a difference!

Step 2: Prepare the Pesto Sauce

Once your veggies are beautifully softened, stir in the pesto sauce along with the reserved pasta water. Let this simmer gently for about 5 minutes. The sauce will begin to thicken as some of the liquid evaporates, melding the bright flavors of pesto with the sweetness of the sautéed veggies, setting the stage for that creamy magic.

Step 3: Create the Creamy Base

In a small bowl, mix the flour with a little warm water until smooth to make a slurry. Remove your pan from heat and slowly whisk in this slurry to avoid lumps. Return to medium heat and pour in the heavy cream, stirring often. Let it simmer for 5 to 10 minutes until the sauce thickens to a silky consistency that clings lovingly to your pasta.

Step 4: Season the Sauce

Now it’s time to add garlic powder, dried oregano, chopped parsley, and black pepper. These aromatic herbs and spices deepen the flavors beautifully and give the sauce a well-rounded, savory kick. Adjust the seasoning with a bit more salt or pepper if needed, ensuring every spoonful tastes just right.

Step 5: Combine Pasta and Sauce

Finally, fold the al dente penne pasta into the sauce, letting it simmer together for about 5 minutes. This step allows the pasta to soak up the creamy, herby goodness, making every bite rich, tender, and utterly satisfying. Your Creamy Pesto Sauce Pasta (Best Easy One Pot Recipe) is now ready to serve!

How to Serve Creamy Pesto Sauce Pasta (Best Easy One Pot Recipe)

Garnishes

To really make your dish pop, sprinkle over some freshly grated Parmesan cheese and an extra handful of chopped parsley. These garnishes add a salty, fresh finish that perfectly balances the richness of the sauce and makes the presentation inviting.

Side Dishes

This creamy pesto pasta pairs beautifully with a light side salad or some roasted vegetables to add crunch and freshness. Think crisp arugula with lemon vinaigrette or oven-roasted cherry tomatoes which complement and contrast the creamy texture wonderfully.

Creative Ways to Present

For a fun twist, serve the pasta in hollowed-out bell peppers or on a rustic wooden board with crusty garlic bread alongside. You can even top with toasted pine nuts or sun-dried tomatoes to add a textured punch and boost the visual appeal for your guests or family.

Make Ahead and Storage

Storing Leftovers

Leftover creamy pesto sauce pasta keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors deepen overnight, making for an even tastier second serving.

Freezing

While the richness of the cream sauce means freezing isn’t ideal, you can freeze the cooked pasta separately without sauce for up to a month. Reheat with fresh pesto and cream added to recapture that fresh, creamy texture.

Reheating

When reheating, do so gently over low heat, adding a splash of milk or pasta water to loosen the sauce if it thickens too much. Stir frequently to avoid sticking and maintain the luscious creaminess you loved initially.

FAQs

Can I use a different type of pasta for this recipe?

Absolutely! While penne holds the sauce well, you can use rigatoni, fusilli, or even farfalle depending on what you have. Just make sure to cook it al dente before combining with the sauce for the best texture.

Is it okay to use store-bought pesto?

Yes, store-bought pesto works wonderfully and saves time. Just choose a high-quality pesto for the best flavor, or use your homemade version if you want that extra fresh touch.

Can I make this recipe vegan or dairy-free?

To make it vegan, substitute the heavy cream with coconut cream or cashew cream and use a vegan pesto version. Nutritional yeast can replace the Parmesan for a cheesy flavor without dairy.

What if I don’t have heavy cream on hand?

You can use half-and-half or whole milk, but the sauce may be less thick and creamy. Adding a bit more flour or reducing the liquid slightly can help maintain the desired consistency.

How can I add protein to this creamy pesto pasta?

Grilled chicken, sautéed shrimp, or crispy tofu cubes are great options to boost the protein content without overpowering the dish. Add them in during the last few minutes of cooking for warm, integrated flavors.
