Creamy Pesto Sauce Pasta Ingredients
Preparing this comforting dish is as easy as pie—let’s gather everything you need!
For the Pasta
• Penne Pasta – This main carbohydrate element should be cooked al dente for the perfect bite.
• Salt – Enhances the flavor of both pasta and sauce; opt for sea salt or kosher for great results.
For the Sauce
• Green Bell Pepper – Adds sweetness and crunch; zucchini or asparagus are great substitutes for a different flavor.
• Red Onion – Provides sweetness and depth; swap for yellow onion if you prefer a milder taste.
• Pesto Sauce – The star flavor agent; whether homemade or store-bought, it’s essential for that authentic taste.
• Reserved Pasta Water – This starchy water helps adjust the sauce’s consistency and enhances creaminess.
• Heavy Cream (35%) – Creates a rich and luscious base; use a plant-based cream for a lighter alternative.
• All-Purpose Flour – Thickens the sauce; gluten-free flour can substitute for dietary restrictions.
• Garlic Powder – Adds savory notes; fresh garlic can be used for a punchier flavor.
• Dried Oregano – Introduces an earthy flavor; Italian seasoning can work as an alternative, too.
• Freshly Chopped Parsley – A bright garnish that adds freshness; using basil amps up the herby notes.

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 for about 10 minutes, stirring occasionally, until the vegetables are softened and the onions are translucent, emitting a sweet aroma that enhances the base of your creamy pesto sauce pasta.
Step 2: Prepare Pesto Sauce
Stir in the pesto sauce and a splash of reserved pasta water into the pan, bringing it to a gentle simmer. Allow the mixture to cook for approximately 5 minutes, stirring frequently, as the sauce begins to thicken and envelop the sautéed vegetables, creating an aromatic blend that sets the stage for your dish.
Step 3: Create Creamy Base
In a small bowl, whisk together flour with warm water until smooth to avoid lumps. Gradually stir this mixture into the skillet, then add the heavy cream. Let the sauce simmer for an additional 5 to 10 minutes, stirring continuously until it becomes rich and creamy, perfectly coating each piece of pasta in the final creamy pesto sauce pasta.
Step 4: Season the Sauce
Add garlic powder, dried oregano, freshly chopped parsley, and black pepper to the creamy mixture. Taste and adjust the seasoning according to your preference, ensuring the flavors harmonize beautifully. This step is crucial for enhancing the overall depth and richness of the creamy pesto sauce pasta.
Step 5: Combine Pasta and Sauce
Toss the cooked penne pasta into the creamy sauce, stirring well to ensure each piece is coated evenly. Allow the pasta to simmer in the sauce for another 5 minutes over low heat, letting the flavors meld together beautifully while the sauce clings to the al dente pasta, creating the perfect creamy pesto sauce pasta experience.
Step 6: Serve
Plate your creamy pesto sauce pasta in warm bowls, garnishing with freshly chopped parsley and an optional sprinkle of grated Parmesan on top. The vibrant colors and inviting aroma will make this comforting dish irresistible, ready to enjoy with family or friends at your next meal.
