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. Once hot, toss in the diced green bell pepper and red onion with 1 teaspoon of salt. Cook for about 10 minutes, stirring occasionally, until the vegetables soften and become slightly caramelized, creating a fragrant base for your creamy pesto sauce pasta.
Step 2: Prepare Sauce
Stir in the pesto sauce along with ½ cup of reserved pasta water into the skillet. Allow the mixture to simmer for about 5 minutes, letting the flavors meld and the sauce thicken slightly. As it simmers, you’ll see the vibrant green of the pesto transform into a richer hue, ready to beautifully coat your pasta.
Step 3: Create Creamy Base
In a small bowl, whisk together 1 tablespoon of all-purpose flour with ¼ cup of warm water until smooth. Slowly add this slurry to the skillet, stirring well to combine. Gradually mix in 1 cup of heavy cream, then reduce the heat to low. Let the sauce simmer for 5 to 10 minutes, stirring occasionally, until it thickens to a luscious, creamy texture.
Step 4: Season Sauce
Add ½ teaspoon of garlic powder, 1 teaspoon of dried oregano, and freshly ground black pepper to taste into the sauce. Stir well to combine, allowing the spices to infuse the creamy pesto sauce. Taste and adjust the seasoning as desired, ensuring every bite of the creamy pesto sauce pasta is bursting with flavor.
Step 5: Combine Pasta and Sauce
Carefully add the cooked penne pasta to the creamy pesto sauce in the skillet. Toss gently to coat the pasta evenly with the sauce, allowing it to simmer for an additional 5 minutes. You’ll notice the pasta absorbing the flavors, becoming a comforting and creamy dish that promises satisfaction in every forkful.
Step 6: Serve
Plate the creamy pesto sauce pasta elegantly, sprinkling with freshly chopped parsley and grated Parmesan cheese if desired. The vibrant colors and luscious texture invite you to dig in.
