Step‑by‑Step Instructions for Creamy Pesto Sauce Pasta
Step 1: Sauté Vegetables
Heat a large skillet over medium heat, adding a drizzle of olive oil. Toss in the diced green bell pepper and red onion, sprinkling with 1 teaspoon of salt. Sauté for about 10 minutes, stirring occasionally until the vegetables have softened and the onions become translucent, releasing their sweet aroma.
Step 2: Prepare Pesto Sauce
Pour in the pesto sauce and reserved pasta water, stirring well to combine with the sautéed vegetables. Allow this mixture to simmer on medium-low for around 5 minutes, letting the flavors meld together and the sauce thicken slightly, coating the vegetables beautifully.
Step 3: Create Creamy Base
In a small bowl, whisk together the all-purpose flour with a couple of tablespoons of warm water to create a smooth slurry. Gradually stir this slurry into the simmering vegetable and pesto sauce. Next, pour in the heavy cream, stirring continuously as you simmer for an additional 5 to 10 minutes, until the sauce has thickened to a luscious consistency.
Step 4: Season the Sauce
Sprinkle in garlic powder, dried oregano, freshly chopped parsley, and black pepper, mixing well to ensure the flavors are evenly distributed. Taste the creamy pesto sauce and adjust with extra salt or seasoning if necessary. The sauce should now have a rich, aromatic profile that will elevate the creamy pesto sauce pasta.
Step 5: Combine Pasta and Sauce
Add the cooked, al dente penne pasta into the skillet, gently folding it into the creamy pesto mixture. Let everything mix together and simmer for about 5 minutes, allowing the pasta to absorb the flavors of the sauce and ensuring it’s completely coated in that delightful creamy texture.
Step 6: Serve
Once done, remove from heat and plate the creamy pesto sauce pasta into bowls. Garnish generously with grated Parmesan and extra parsley for a pop of color. Enjoy the creamy, comforting dish immediately, sharing it with family or friends for a warm, inviting dinner experience.
