Creamy Pesto Sauce Pasta Ingredients
Dive into this recipe with all the essentials you need for your delicious dish!
For the Pasta
• Penne Pasta – The perfect shape that holds the creamy sauce beautifully; opt for gluten-free if needed.
For the Sauce
• Salt – Enhances flavor; kosher or sea salt works best for this recipe.
• Green Bell Pepper – Adds a sweet and crunchy texture; swap for yellow or red bell peppers for an even sweeter kick.
• Red Onion – Offers a lovely sharp contrast; use yellow onion if you prefer a more subtle flavor.
• Pesto Sauce – The star ingredient that imparts vibrant herbaceous notes; go for store-bought or homemade, and consider basil or sun-dried tomato varieties for extra flair.
• Reserved Pasta Water – Helps create that creamy texture by emulsifying the sauce; don’t forget to save some!
• Heavy Cream (35%) – Contributes to a luscious sauce; half-and-half can lighten things up, or coconut cream works well for a dairy-free alternative.
• All-Purpose Flour – Acts as a thickening agent; cornstarch is a great gluten-free swap.
• Garlic Powder – Adds depth and warmth to the sauce; fresh minced garlic is a fantastic alternative for an even richer flavor.
• Dried Oregano – Infuses a lovely aromatic essence; fresh oregano is a delightful upgrade if available.
• Freshly Chopped Parsley – A bright garnish that enhances the dish’s visual appeal; basil or chives can also work remarkably well.
• Black Pepper – Provides a hint of warmth; adjust quantities to suit your heat preference.
• Grated Parmesan – An optional topping that elevates the dish with umami flavor; use nutritional yeast for a vegan twist.
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 along with 1 teaspoon of salt. Sauté for about 10 minutes, stirring occasionally, until the vegetables are softened and lightly golden. You’ll notice their vibrant colors enhancing the dish as they caramelize, creating a flavorful base for your creamy pesto sauce.

Allow the mixture to simmer for about 5 minutes, stirring occasionally until it thickens slightly and the flavors meld beautifully. The rich aroma will fill your kitchen, promising deliciousness in every bite of your creamy pesto sauce pasta.
Step 3: Create Creamy Base
In a separate bowl, whisk the all-purpose flour with a bit of warm water to create a smooth slurry. Gradually add this slurry to the pan, then gently mix in the heavy cream, stirring continuously. Let this simmer for 5 to 10 minutes until the sauce thickens and becomes creamy. Keep an eye on it to ensure a luscious, velvety texture that hugs the pasta perfectly.
Step 4: Season Sauce
Once your creamy mixture is thickened, add garlic powder, dried oregano, freshly chopped parsley, and black pepper to taste. Stir well, adjusting the seasoning as needed to suit your palette. The fragrance of the herbs will brighten the dish, enhancing the overall flavor profile of your creamy pesto sauce pasta.
Step 5: Combine Pasta and Sauce
Add the cooked penne pasta directly to the sauce, gently tossing to combine. Allow everything to simmer together for about 5 minutes. This step ensures that the pasta absorbs the flavors of the creamy pesto sauce, making each bite an explosion of delight. You’ll see the pasta glisten with the sauce!
