Ingredients You Will Need for Creamy Pesto Pasta

Everything here is an everyday ingredient. This is the exact list we use for this one, measured the way we actually cook it.

Base

• 3 cups penne pasta cooked al dente
• 1/2 cup reserved pasta water
• 1 1/2 tbsp all purpose flour

Dairy

• 2 cups heavy cream

Produce

• 1 red onion diced
• Freshly chopped parsley a handful

Seasoning

• 2 tsp salt divided
• 1 green bell pepper diced
• 1 tbsp garlic powder
• 1 tbsp dried oregano
• 1 tsp black pepper

Pantry

• 6 tbsp pesto sauce
• Grated Parmesan for topping optional

A quick word on the parts that matter most in it:

• Penne pasta cooked al dente. Cook it a minute short of the package time, since it keeps cooking once it hits the hot sauce.
• Green bell pepper diced. It adds color, texture and a little freshness against the richer parts of the plate.
• Red onion diced. Let it soften slowly rather than rushing it. Burnt garlic turns bitter and there is no fixing it.

How to Make Creamy Pesto Pasta

Here is exactly how we make the dish: about 5 minutes of prep and roughly 10 minutes of cooking.

What you need: Large Skillet, Whisk, Mixing Bowl.

1. Heat a large pan over medium heat. Add the diced green bell pepper and red onion with 1 teaspoon salt. Saute for about 10 minutes, stirring occasionally, until the vegetables are softened and lightly caramelized.
2. Add the pesto sauce and reserved pasta water to the sauteed vegetables. Stir to combine and let it simmer for about 5 minutes until the sauce thickens slightly and the water evaporates.
3. In a small cup or bowl, whisk together the flour and a little warm water to make a smooth slurry. Remove the pan from the heat and gradually stir in the slurry to avoid any lumps.
4. Once fully incorporated, return the pan to medium heat and pour in the heavy cream. Simmer for 5 to 10 minutes, stirring often, until the sauce thickens.
5. Add the garlic powder, oregano, freshly chopped parsley, and black pepper to the sauce. Stir well and adjust seasoning with additional salt and pepper, to taste.
6. Toss in the cooked penne pasta and let everything simmer together for about 5 minutes, allowing the pasta to absorb the sauce and all the flavors to meld beautifully.
7. Plate the creamy pesto pasta, and if desired, top with freshly grated Parmesan. Garnish with extra parsley for a fresh finish.

That is the whole method. Nothing here needs special technique, just a little attention at the right moments.

Tips for the Best Creamy Pesto Pasta

None of this is complicated, but these are the small habits that separate a good plate of this recipe from a great one.

• Salt the pasta water generously. It is the only chance to season the pasta itself.
• Save a cup of the starchy cooking water. A splash brings a sauce together better than anything else.
• Pull the pasta a minute early. It keeps cooking once it meets the hot sauce.
• Read the steps once before you start. Knowing what is coming makes the whole thing calmer.
• Have everything measured and within reach before the heat goes on. Have everything measured and within reach before the heat goes on.

Taste as you go and adjust the seasoning at the end rather than the beginning. This dish rewards a little attention right at the finish.

Variations and Add Ins

Creamy pesto pasta takes changes well, so treat the recipe above as a starting point rather than a set of rules. These are the swaps we come back to most often.

• Change the shape. Anything with ridges or curves holds this sauce well.
• Add protein. Chicken, beef or shrimp turn it into a full dinner.
• Sneak in vegetables. Spinach, peas or broccoli stir in at the end with no fuss.
• Make it lighter. Half and half in place of cream keeps it silky with less richness.
• Change the herbs. Fresh parsley, basil or dill at the end each send it somewhere slightly different for no extra effort.
• Make it a bigger meal. Serve it over rice or with warm bread and it stretches to feed another person or two.

Change one thing at a time rather than three. That way you find out what you actually like in the recipe instead of guessing at the end.

How to Store and Reheat Creamy Pesto Pasta

Leftovers keep in an airtight container in the refrigerator for up to three days. Pasta drinks up sauce as it sits, so add a splash of broth or cream when you reheat it and stir until it loosens up again.

If you are cooking ahead on purpose, prep the components and keep them separate until you are ready. It takes a few minutes off a busy evening and this one holds its texture far better that way.

What to Serve With Creamy Pesto Pasta

It carries a plate on its own, but a few simple things turn it into a proper dinner.

• A green salad with a sharp dressing. Simple, and it soaks up everything on the plate.
• Garlic bread. A little contrast keeps the whole plate from feeling heavy.
• Roasted broccoli. Easy to put together while the main event finishes.
• A glass of sparkling water with lemon. The kind of small addition that makes dinner feel finished.
