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 with 1 teaspoon of salt. Sauté the vegetables for about 10 minutes, stirring occasionally, until they soften and turn golden brown, creating a delightful aroma that fills your kitchen.
Step 2: Prepare the Pesto Sauce
Once the vegetables are beautifully caramelized, stir in your pesto sauce along with a splash of the reserved pasta water. Allow this mixture to simmer gently for 5 minutes, thickening up and letting those vibrant flavors meld together, ensuring each bite of your creamy pesto sauce pasta is infused with taste.
Step 3: Create the Creamy Base
In a small bowl, combine all-purpose flour with warm water to form a smooth slurry. Gradually mix this into the simmering sauce, then slowly add the heavy cream while stirring constantly. Let the sauce simmer for an additional 5 to 10 minutes until it thickens to a luxurious consistency, ready to coat the pasta beautifully.
Step 4: Season the Sauce
Now it's time to season! Add garlic powder, dried oregano, freshly chopped parsley, and black pepper to your creamy pesto sauce. Stir well to blend the flavors, and taste for balance, adjusting the seasoning according to your preference for that perfect finishing touch.
Step 5: Combine Pasta and Sauce
Toss in the cooked penne pasta, stirring gently to coat every piece evenly with the rich creamy pesto sauce. Let it simmer together for about 5 minutes, allowing the pasta to soak up the sauce and become deliciously intertwined with the vibrant flavors of your creamy pesto sauce pasta.
Step 6: Serve
Plate your creamy pesto sauce pasta generously, garnishing it with freshly grated Parmesan and a sprinkle of extra parsley if desired. This dish not only looks inviting but is also a delectable feast for your taste buds, perfect for elevating your weeknight dinners!

Creamy Pesto Sauce Pasta Recipe FAQs
How do I choose the right bell peppers for my dish?
Absolutely! Look for bell peppers that are firm to the touch and have smooth, shiny skin. Avoid those with dark spots or wrinkles, as these can indicate age or spoilage.

What is the best way to store leftover creamy pesto sauce pasta?
