Step‑by‑Step Instructions for Creamy Pesto Sauce Pasta
Step 1: Sauté the Vegetables
Heat a large skillet over medium heat and add diced green bell pepper and red onion along with 1 teaspoon of salt. Sauté for about 10 minutes, stirring occasionally, until the vegetables are softened and lightly caramelized, turning a golden hue that signals their readiness.
Step 2: Prepare the Pesto Sauce
Once the vegetables are perfectly sautéed, stir in your creamy pesto sauce and carefully add ½ cup of reserved pasta water. Let the mixture simmer for about 5 minutes, allowing the flavors to meld while the sauce thickens to a luxurious consistency.
Step 3: Create the Creamy Base
In a small bowl, whisk together 2 tablespoons of all-purpose flour with ¼ cup of warm water to make a smooth slurry. Gradually add the slurry to the simmering sauce, mixing thoroughly. Slowly pour in 1 cup of heavy cream, and let the sauce simmer for 5-10 minutes, thickening it to a delightful creaminess reminiscent of the best creamy pesto sauce pasta.
Step 4: Season the Sauce
With the sauce at your desired thickness, sprinkle in 1 teaspoon of garlic powder, 1 teaspoon of dried oregano, and a generous dash of freshly cracked black pepper. Stir well, tasting to adjust the seasoning to your preference, ensuring that every bite of your creamy pesto sauce pasta is bursting with flavor.
Step 5: Combine Pasta and Sauce
Add your cooked penne pasta directly into the skillet with the creamy pesto sauce. Gently toss everything together and let it simmer for another 5 minutes on low heat, allowing the pasta to soak up that rich, herby flavor, creating a truly comforting dish.
Step 6: Serve
Once everything is well combined and heated through, plate the creamy pesto sauce pasta. Garnish generously with freshly chopped parsley and sprinkle grated Parmesan on top if you desire, presenting a beautiful and inviting meal perfect for any weeknight gatherings.
