Step‑by‑Step Instructions for Creamy Pesto Sauce Pasta
Step 1: Sauté Vegetables
Heat a large skillet over medium heat and add diced green bell pepper and red onion with 1 teaspoon of salt. Sauté for about 10 minutes, stirring occasionally, until the vegetables are softened and lightly caramelized, giving off a delicious aroma. This initial step builds a flavorful foundation for your creamy pesto sauce pasta.
Step 2: Prepare Pesto Sauce
Once the vegetables are nicely sautéed, mix in the pesto sauce and ½ cup of reserved pasta water. Allow the mixture to simmer for about 5 minutes, stirring frequently until the sauce thickens slightly and clings to the veggies. This step helps enhance the rich herbaceous flavor that will coat your pasta beautifully.
Step 3: Create Creamy Base
In a small bowl, whisk together all-purpose flour with ¼ cup of warm water to form a smooth slurry. Gradually pour this slurry into the skillet while stirring continuously, then stir in 1 cup of heavy cream. Let the sauce simmer for another 5-10 minutes, until it thickens and reaches a luscious texture that promises to envelop every bite of pasta.
Step 4: Season Sauce
Stir in garlic powder, dried oregano, freshly chopped parsley, and black pepper to taste. Allow the mixture to bubble gently for a few minutes, and take a moment to adjust the seasoning if needed. This step rounds out the flavors in your creamy pesto sauce pasta, inviting warmth and depth.
Step 5: Combine Pasta and Sauce
Gently toss in the cooked penne pasta to the sauce, ensuring each piece is thoroughly coated. Let everything simmer together for another 5 minutes so that the pasta can absorb the delightful flavors of the sauce. This melding of ingredients creates a comforting and satisfying dish.
Step 6: Serve
Plate the creamy pesto pasta, and feel free to sprinkle some grated Parmesan cheese on top along with extra parsley for a pop of color. Serve hot, enjoying the inviting aroma and the rich, creamy texture that makes this dish irresistible for weeknight dinners.
