Step‑by‑Step Instructions for Creamy Pesto Sauce Pasta
Step 1: Sauté Vegetables
Begin by heating a large skillet over medium heat. Add diced green bell pepper and red onion along with 1 teaspoon of salt. Sauté the vegetables for about 10 minutes, stirring occasionally, until they soften and caramelize, turning slightly golden. This step builds a flavorful base for your creamy pesto sauce pasta.
Step 2: Prepare Pesto Sauce
Once the vegetables are tender, stir in your favorite pesto sauce along with ½ cup of the reserved pasta water. Allow this mixture to simmer for about 5 minutes, letting the flavors meld together while thickening slightly. You’ll see the vibrant green color of the pesto becoming even more luscious and aromatic.
Step 3: Create Creamy Base
In a separate bowl, whisk together 2 tablespoons of all-purpose flour with ¼ cup of warm water to create a slurry. Gradually incorporate this slurry into the simmering pesto sauce, stirring continuously. Then add 1 cup of heavy cream, letting it simmer for an additional 5 to 10 minutes, until the sauce thickens and coats the back of a spoon beautifully.
Step 4: Season the Sauce
To deepen the flavor of your creamy pesto sauce pasta, stir in 1 teaspoon of garlic powder, 1 teaspoon of dried oregano, and ¼ cup of freshly chopped parsley. Season with black pepper to taste. Allow the sauce to simmer for another minute, ensuring the herbs release their delightful aroma, enhancing the overall dish.
Step 5: Combine Pasta and Sauce
Next, toss in the cooked penne pasta, stirring to fully coat it in the rich sauce. Let everything simmer together for another 5 minutes, allowing the pasta to absorb some of that delicious creamy pesto. This melding of flavors makes each bite a tantalizing experience.
Step 6: Serve
Once plated, garnish your creamy pesto sauce pasta with grated Parmesan cheese and additional parsley for a fresh touch. A sprinkle of black pepper adds the finishing flourish, making your dish not only delicious but visually inviting. Enjoy this comforting meal that’s both quick and elegant!
