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!

Making Creamy Pesto Pasta sauce roux

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.

Creamy Pesto Pasta Recipe

A 10-minute creamy pesto pasta made with just five simple ingredients and no heavy cream, this delicious dish is perfect for busy weeknights. Perfect on it's own or with your favorite cooked protein.
Prep Time1 minute
Cook Time9 minutes
Total Time10 minutes
Yield: 6 servings
Author: Jami Boys

Equipment

  • 4-6 quart stock pot
  • 3-quart saucepan
Click for Cook Mode

Ingredients

  • 1/4 cup butter
  • 1/4 cup flour* (see notes for gluten free option)
  • 2 cups milk
  • ½ to 1 teaspoon salt to taste
  • ½ to ¾ cup pesto to taste
  • ¾ pound pasta
  • optional pasta water or milk

Instructions

  • Start the water boiling for the pasta. When it boils, cook as directed on the package.
  • Meanwhile, make a white sauce by melting the butter in a medium sized saucepan over medium heat. Whisk in the flour until combined; cook for a couple minutes, stirring constantly. Slowly add the milk and stir over medium-high heat until thickened (TIP: If too thick, add a bit of reserved pasta water or a bit more milk, though it will thin when the pesto is added, too.)
  • Add the pesto to the white sauce, stir and remove from heat.
  • Drain the pasta and return pasta to the pot. This is where you can add cooked protein, spinach, dried tomatoes or cheese.
  • Toss the sauce with the pasta in the pot and serve.

Notes

*Flour: Some have mentioned this being too much flour or tasting “floury.” I based the recipe on the classic white sauce ratio of 2TB butter and flour to 1 cup milk, simply doubled for the recipe. That said, if it seems too much for you, you can decrease it to 3TB, but much lower than that and your sauce many not thicken.
Variations:
  • Add cooked chopped cooked chicken, shrimp, sausage, or smoked salmon.
  • Add chopped fresh spinach along with the sauce and toss it all together.
  • Add chopped dried tomatoes.
  • Top pasta with fresh chopped tomatoes.
Gluten Free Option:
Omit flour and use 1 tablespoon of cornstarch or potato starch, whisking it into the cold milk before pouring into the melted butter. Whisk as directed over the heat until thickened and proceed with the recipe (if it’s not thick enough, whisk more starch, 1/2 tablespoon at a time, to a small amount of cold milk and add to the heating sauce).

Creamy Pesto Pasta FAQs

How do you thicken creamy pesto pasta?

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).

What can you serve with pesto pasta?

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.

What does creamy pesto taste like?

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!)

  1. Great recipe! Thank you! The first time I made this dish I kept it all veggies. The second time around I added heavy cream and grilled chicken.5 stars

  2. This was so delicious! Made my own pesto, added sun dried tomatoes and grilled chicken. I also used half and half and reduced the flour by 1TBSP. Such an amazing and simple recipe I will definitely make again! Thank you!5 stars

    1. Oh, yum – that sounds great! I’m so glad you enjoyed this simple recipe like we do – thank you for the review!!

  3. Marinated shrimp in olive oil, garlic, salt and red pepper flakes. Marinated cherry tomatoes on olive oil, shallots, garlic and salt. Used half and half instead of milk, but thinned the sauce with pasta water and milk. Added grated parmesan to the sauce and a little salt. AMAZING! Every one of my children….including hubby loved it! Putting this in the rotation.5 stars

  4. Added Romano cheese to the sauce, sautéed diced chicken in olive oil and garlic and onion powders and substituted Half and Half for the milk. The changes made this a keeper for us. 1/2 cup of the pesto was plenty.5 stars

  5. Yum!!! I’m finishing this right now, because I saw the comments of the sauce thickening, I took about a tbs of the flour out of the mix everything else the same. At the end when mixing with pasta I had set aside a cup of the pasta water and slowly added to it so it’s not so “gummy” and a clove of finely chopped garlic since the husband thinks it needed a kick of something. I think like everything is a matter of adding your own to fit your family. Thanks for the recipe 😉5 stars

  6. OMG what an awesome recipe, made this tonight and it is great. I had the same issue with it becomeing a roux but just added the milk and it was a sauce. Added homemade pesto and chicken breast chunks and it was delicious.
    Thank You for this recipe!!+5 stars

  7. I actually found it very hard to make the sauce. It was very gooey like thick and gummy. I did the 2 tbsp. Of flour and butter and immediately got gummy, I tried olive oil to smooth it out but it was basically inedible. The pasta dinner was ruined. Cream sauce not easy.

    1. I’m so sorry, Mavis, I know that would be disappointing.
      Not sure what could’ve happened – you can see from the photos that flour and butter usually make a classic roux that thickens sauces. 😕

  8. Can I say it, OMG? This was so easy and so good. I added Parm Cheese and Grilled Chicken. OMG x 2!5 stars

  9. This is so simple and so delicious! My husband also is not a fan of full on pesto, so this was a perfect compromise. 🙂 I made some turkey meatballs and let them simmer in the sauce. We enjoyed this very much!5 stars

  10. To save time, could I use a jar of alfredo sauce to mix with the pesto? Or would it taste different? Looks so delish, going to make that tonight but with shrimp!

  11. 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 spagetti with pesto and it tasted like a fine restaurant meal. Will def be making your recipe again. I actually love all your recipes that I have tried from this site:)
    Thanks
    Teresa5 stars

    1. Thank you so much, Teresa! It’s such a simple and good tasting recipe – and I bet it went great with the shrimp, I’ll have to try that!

  12. Oh my goodness…why didn’t I think of this…I make white sauce, and love pesto but haven’t thought about putting them together!! YAY!!!5 stars

  13. That sounds so good, I’ve placed it on our Monthly meal plan for next month. But I think I’ll add leftover grilled chicken to make it more hearty for my hubs. He said he’d try it…he’s never had pesto anything…picky eater of mine 🙂

    1. I had just made some pesto, over the weekend with my son, needless to say it is really delicious. I love pesto. My favorite is on grilled chicken either hot or cold. I also like pesto with pasta but I never thought of making a white sauce and adding to the pesto. I just use pesto and toss over pasta. While Troy (my son) and I were making this I said I had no pine nuts but I do have every other kind so we heated several handfuls of walnuts in the skillet then added this to the basil and also added lemon basil in the food processor. It is very good. This was the first time I ever tried lemon basil and I will surly plant that again next year.

  14. You are making me hungry……..I also make a similer pasta as a go to dish. I take what ever random veggies I have in the fridge and saute them in a pan with some olive oil and basil (just dry, I don’t have pesto in my freezer 😉 Once the veggies are done I sprinkle about 2 tbs of flour over it and cook for a minute or two. Then I add my two cups of milk and cook unitl thick. It’s quick, easy, delicious and used up veggies that might otherwise have gone bad.

  15. I just learned the beauty of making my own white sauce to use in place of a can of cream of soup. I also made my own pesto this summer and froze it. Was so glad to have this in the freezer this winter! I will be making this amazing creamy pasta with it for sure.5 stars
