Creamy Pesto Sauce Pasta Ingredients
For the Pasta
• Penne Pasta – Provides the main carbohydrate structure; feel free to choose gluten-free pasta if desired.
• Salt (divided) – Enhances overall flavor; using kosher salt or sea salt will elevate the taste.
For the Vegetables
• Green Bell Pepper – Adds sweetness and vibrant color; substitute with red or yellow bell pepper for a sweeter profile.
• Red Onion – Brings a mild sharpness to the dish; can be swapped with yellow onion for a stronger flavor.
For the Sauce
• Pesto Sauce – Acts as the primary flavoring agent; both store-bought and homemade pesto work beautifully.
• Reserved Pasta Water – Crucial for emulsifying the sauce and adjusting consistency; always reserve some before draining.
• Heavy Cream (35%) – Delivers rich creaminess to the sauce; half-and-half can be a lighter alternative.
• All-Purpose Flour – Thickens the sauce; opt for cornstarch or a gluten-free flour blend for a gluten-free version.
• Garlic Powder – Adds depth; fresh minced garlic is a fantastic upgrade if available.
• Dried Oregano – Introduces aromatic herb notes; feel free to use fresh oregano for a more vibrant taste.
For Garnishing
• Freshly Chopped Parsley – Adds freshness and color; basil can be a great substitute for an Italian flair.

Step‑by‑Step Instructions for Creamy Pesto Sauce Pasta
Step 1: Sauté Vegetables
In a large skillet, heat a splash of olive oil over medium heat. Add diced green bell pepper and red onion along with 1 teaspoon of salt. Sauté them for about 10 minutes, stirring occasionally, until the vegetables become softened and slightly caramelized, creating a sweet aroma that invites you to continue.
Step 2: Prepare Pesto Sauce
Once the vegetables are ready, add the pesto sauce along with a splash of the reserved pasta water to the skillet. Stir thoroughly and let the mixture simmer for around 5 minutes, allowing the flavors to meld together and the sauce to thicken slightly. You’ll know it’s ready when it clings beautifully to the veggies.
Step 3: Create Creamy Base
In a small bowl, whisk together flour and warm water to create a smooth slurry. Gradually stir this mixture into the simmering sauce, then add the heavy cream. Let it cook for another 5 to 10 minutes, stirring regularly until the sauce thickens to a creamy consistency that coats the back of a spoon.
Step 4: Season the Sauce
To elevate the flavor of your creamy pesto sauce pasta, mix in garlic powder, dried oregano, and the freshly chopped parsley. Taste and adjust with more black pepper and salt if desired. The sauce should be fragrant and bursting with herbaceous goodness, ready to embrace the pasta.
Step 5: Combine Pasta and Sauce
Now it’s time to bring it all together! Toss in your cooked penne pasta, stirring gently to ensure the pasta is well coated with the creamy pesto sauce. Let it simmer for about 5 minutes, allowing the pasta to absorb all those rich flavors while heating through perfectly.
Step 6: Serve
Carefully plate your creamy pesto sauce pasta and finish with a sprinkle of grated Parmesan and extra parsley for a touch of color. Serve warm, and enjoy each delightful bite of this comforting dish that transforms a simple meal into something truly special!
