Pasta with homemade pesto is a good, classic recipe that is a staple of many Italian restaurants.
But pasta with a creamy pesto sauce is a great recipe. Adding a simple creamy white sauce elevates pesto to a whole new level.
What is pesto?
Pesto is traditionally a mixture of olive oil, basil, pine nuts, and parmesan with salt added for flavor. The ingredients have been mashed together for centuries in a mortar and pestle, though a food processor or blender does the work for us now.
There are also now many variations where the basil is replaced with other herbs, pine nuts with other nuts, and even use other cheeses.
This recipe for what I call a “frugal” pesto is a riff on the classic, replacing the expensive pine nuts with a much cheaper ingredient that I think makes it taste even better!
Pasta with Only Pesto?
Back when we were first married, Brian and I went to an Italian restaurant and ordered pasta with pesto. I thought it was good. Brian thought it was like “eating chopped grass” with his pasta, lol.
So when I started growing basil and making pesto to keep in our freezer all winter long (yes, really!), I had to figure out a way to have pasta with pesto that wasn’t quite so “grassy.” Well I suppose I didn’t have to, but I wanted to because it’s such an easy meal on its own, or mixed with chicken and dried tomatoes, or even as a side dish alongside chicken or sausage – and of course a kid pleaser.
Enter creamy pesto pasta – the dish we could ALL enjoy, while only adding a couple minutes to the preparation.
What is Creamy Pesto Pasta Made Of?
My solution was to create a creamy white sauce of butter, flour, and milk and then mix it with pesto. You could also just heat heavy cream until it thickened a bit and add the pesto, but I wanted a thicker sauce than that would produce, kind of like an Alfredo.
And this creamy pasta has become one of our family’s favorite dishes – and yes, even Brian.
Plus it’s one of those recipes I always have the ingredients for and is so fast (10 minutes!) that when we are tempted to buy something to eat on our way home from something, I always think “I could have creamy pesto pasta made in less time than it would take to get fast food.” Having recipes like these in our back pocket makes it easier to stick to a budget and bypass those times we’re tempted to order out.
Ingredients
- Pasta of choice (I always try to use a whole grain or healthier pasta – I really like this brand of chickpea pasta for added protein)
- Premade pesto – preferably what you’ve made and stashed in your freezer when basil was in season.
- Milk – some people have used half and half for a richer sauce. I haven’t tried this with a milk substitute.
- All-purpose flour – you can use 1 tablespoon of cornstarch or potato starch to keep it gluten free – whisk it into the cold milk before pouring into the melted butter and whisk over the heat until thickened.
- Butter
- Optional variations: Add cooked protein like chicken, shrimp, or chickpeas, vegetables like spinach or dried tomatoes mixed in, or chopped fresh tomatoes served on top.
Note on Making a White Sauce
Making a white sauce is really very simple, I promise. I didn’t use to think so, back when I made everything with a can of cream-of-something soup, but once I learned how there was no going back. Especially when I realized that a white sauce has only four ingredients (butter, flour, milk, and salt) and the canned creamed soups have…well, a lot (including things I don’t recognize as food). And it goes without saying that the taste of homemade white sauce is way better!
Directions
Timing Tip: Start the water boiling first before starting the sauce, adding the pasta to the water when it’s ready as you’re making the white sauce. In this dish, it’s the pasta that needs the most time to cook. See? Really just 10 minutes!
Step 1: Melt the butter in a medium saucepan. Add the flour and mix well over medium heat. You just want it combined and bubbly a bit like shown above, but not brown (that’s becoming a roux, then).
Step 2: Slowly add the milk, stirring with a whisk. Cook and stir until the sauce thickens. Add a teaspoon of salt or to taste. TIP: add pasta water or more milk if sauce is too thick for your tastes (though the pesto will thin it more).
You’ve made a white sauce! How easy is that? I can’t believe I ever thought it was hard.
Step 3: When the sauce has thickened, add the pesto and stir together. This can be to your taste – I usually add one of my small containers of frozen pesto which are between 1/2 and 2/3 cup. It’s just about right for this amount of white sauce.
Step 4: Drain the pasta and return it to the pot. Then add the creamy pesto sauce to the pasta and toss until the noodles are coated.
What to serve with creamy pesto pasta?
Serve as is with a salad (I love it with this orange-almond salad) or use as a base for rotisserie chicken or cooked shrimp.
This is also a great side dish or potluck option served with roasted sausages, grilled chicken, or easy mini meatloaves.

“I made this tonight and it was wonderful. Two days ago I made the homemade pesto from your recipe and froze some of it. I saved some for tonight for the white sauce, then I added sautéed shrimp to my thin spaghetti with pesto and it tasted like a fine restaurant meal. Will def be making your recipe again.” -Teresa

Creamy Pesto Pasta FAQs
You can use the method in this recipe – making a white sauce of flour, butter, and milk before adding the pesto – or use heavy cream and cook on low until it thickens slightly (it will be runnier than a white sauce).
Another option is to thicken your pesto with potato starch or corn starch and add a milk product until it’s as creamy as you wish (this is a good dairy-free alternative).
Any pesto pasta can be served on its own as a light meal. It can also be a side dish to any grilled or roasted meat or seafood.
It’s also a wonderful based to add ingredients too, like sautéed spinach, onions, and peppers, cooked chicken or shrimp, or any leftovers you need to use up.
All the things you love about pesto – the flavor from garlic, basil, and parmesan – are there int he creamy version, but just a bit lighter with less bite. The texture is smoother, too, with less of a feel of chopped herbs (for want of a better description!)
