Step‑by‑Step Instructions for Creamy Pesto Sauce Pasta
Step 1: Sauté the Vegetables
In a large skillet over medium heat, drizzle a little olive oil and add 1 diced green bell pepper and 1 sliced red onion, along with 1 teaspoon of salt. Sauté the vegetables for about 10 minutes, stirring occasionally, until they soften and caramelize, achieving a golden hue that enhances their natural sweetness.
Step 2: Incorporate the Pesto Sauce
Once the vegetables are beautifully tender, stir in your choice of pesto sauce along with a splash of reserved pasta water. Allow this mixture to simmer for an additional 5 minutes, which will help the flavors meld together while slightly thickening the sauce, giving it a rich aroma that fills the kitchen.
Step 3: Create the Creamy Base
In a small bowl, whisk together 2 tablespoons of all-purpose flour with a bit of warm water until smooth to create a slurry. Gradually stir this slurry into the pesto mixture in the skillet, and then gradually add 1 cup of heavy cream. Simmer the sauce for 5–10 minutes until it thickens, revealing a luscious, creamy texture that will cling to your pasta.
Step 4: Season the Sauce
To elevate the flavor of your creamy pesto sauce pasta, mix in a teaspoon of garlic powder, a teaspoon of dried oregano, and a generous sprinkle of black pepper. Stir in 2 tablespoons of freshly chopped parsley, adjusting the seasoning to taste. This step brings a delightful freshness and aroma, making the sauce even more enticing.
Step 5: Combine with Pasta
Add your cooked penne pasta directly into the skillet with the creamy sauce, making sure each piece is well coated. Toss everything together gently and let it simmer for about 5 minutes. This allows the pasta to absorb the delicious flavors of the creamy pesto sauce, transforming it into a comforting dish.
Step 6: Serve and Garnish
Plate the creamy pesto sauce pasta into bowls and optionally top each serving with freshly grated Parmesan cheese and extra parsley for a burst of color. The vibrant green sauce, combined with colorful vegetables, creates a beautifully inviting presentation, perfect for enjoying with family or friends.

Tips for the Best Creamy Pesto Sauce Pasta
Perfectly Cooked Pasta: Ensure you cook the penne until al dente—this gives it a good bite and keeps it from becoming mushy when mixed with the sauce.
Fresh Ingredients: Opt for fresh vegetables and pesto to elevate the flavor; these vibrant elements create a more aromatic and satisfying dish.
Adjust Consistency: Use reserved pasta water sparingly to adjust the sauce’s thickness; remember that a little goes a long way!
Best Creaminess: Gradually adding heavy cream while stirring helps to create a silky texture; avoid boiling after adding the cream to prevent curdling.
Season to Taste: Don’t forget to taste and adjust the seasonings at the end; everyone’s preference is different when it comes to salt and spices.
Storage Savvy: If you plan to store leftovers, leave out the Parmesan until serving to maintain the best texture and flavor for your creamy pesto sauce pasta.
How to Store and Freeze Creamy Pesto Sauce Pasta
Fridge: Store leftovers in an airtight container for up to 3 days. This helps maintain the creamy texture while keeping the flavors intact.
Freezer: For longer storage, freeze the creamy pesto sauce pasta in a freezer-safe container for up to 2 months. Be sure to cool it completely before freezing to maintain quality.
Reheating: When ready to enjoy, thaw in the fridge overnight and reheat gently on the stove or in the microwave. Add a splash of reserved pasta water or cream for extra creaminess.
