This cozy bowl of Crispy Roasted Cauliflower with Creamy Pesto Pasta is THE best any night of the week wintery pasta. Taking a classic pesto pasta recipe and updating it with a no cream, creamy pesto sauce, crispy cauliflower, and lemony arugula. Every twirl of pasta has delicious, comforting but fresh flavors that melt in your mouth. It’s the coziest, creamiest bowl of healthier pasta that’s fancy enough for the weekend, but easy enough to make any night of the week. And most importantly, it’s delicious!

We’ve made it to the first Thursday of the New Year, which means we’re almost one week into 2021. And while the world is still a little wonky (to put it nicely), it’s been a pretty great start to the new year. We’ve already cooked up a handful of delicious recipes, all made with a slightly healthier spin. And we’re closing out the savory recipes for the week with pasta, which is never a bad idea.
This isn’t just your average bowl of pesto pasta either, it’s extra special. How it came to be is a mash-up of ideas and plenty of thinking, writing, and reworking. And while it took me a minute to get everything just right, I couldn’t love the recipe more.
In fact, it might be one of my favorites from the week. Though I’ve loved every recipe this week, sooo, I will not choose a favorite. But just know this pasta is REALLY GOOD. And what’s even better? It’s very well balanced with plenty of vegetables and herbs. It’s also easily adaptable to make completely vegan too.

Start with the cauliflower. Which is actually the heart of this recipe, and where the idea for this pasta all started.
I wanted to make an extra crispy roasted cauliflower. It’s been a while since I’ve used cauliflower. So when looking back through older posts while gathering recipes for last week’s Favorite Healthy Recipes, I came across my cauliflower salad. Oh, how I love this salad. I remember that my family all loved it so much too.
It’s truly one of my best salads, and it’s the cauliflower that makes it. I took that cauliflower recipe, and used it within this pasta. It’s oven-roasted with lots of garlic and spices. By the time it comes out of the oven, it’s extra crispy with just the right amount of char and so much flavor. It is delicious! Especially atop a big bowl of creamy pesto pasta.

For the pasta, I made a quick basil pesto, but with a few additions that make this even better. I added lemon for freshness, and jalapeño for an unexpected but delicious spicy kick. I know it sounds odd with all these Italian flavors, but if you love a Greek style goddess dressing, you’ll love this pesto. It’s very similar.
Once the pesto is made, boil up your favorite cut of pasta. I really like using a longer cut…fettuccini or bucatini are my usual go-to’s. Add the hot pasta right back to that pot you boiled it in, then add all the pesto and a splash of creamy coconut milk. The coconut milk helps to create a luscious sauce without adding in any cream. And I promise, you don’t taste even the slightest hint of coconut!

Immediately the heat from the pasta intensifies the smell of the basil…leaving you with nothing but excitement for dinner. And trust me, you should be excited. Every bowl of pasta is creamy, just oh so slightly spicy, with a subtle pesto touch. And the crispy cauliflower on top adds additional texture and flavor.
It’s is so very good. Roll your eyes back, go for that second bowl, and finish the pasta all in one sitting, GOOD. Dramatic, but true.

It’s different, but so, so good.
And again, the crispy cauliflower is a game-changer. The flavor is intense, but the texture and seasoning are spot on. It adds a saltiness that keeps everyone coming back for seconds.
The perfect winter pasta…just made with a few slightly healthier swaps!

Do you have any suggestions for substituting the nuts? My son has a nut allergy. Or do you think the pesto will taste good without it?
Hey Jill,
I would skip the nuts, sunflower seeds would also work well here. I hope you love the recipe. Please let me know if you have any other questions! xTieghan
When I plunked his plate in front of him, my husband said, “Where’s the meat?!” But after just one bite, he was sold. We’ve made this twice in one week, and savored each bite. Thank you for coming up with such a fast, easy, comforting and delicious meal we can enjoy as a hearty go-to! (I just used store-bought pesto, though I’m sure yours would make it just that much better!). We love it, and it’s now on our regular rotation!
Hey Katie,
Thanks so much for trying the recipe. I am glad you enjoyed it! xTieghan
I just made this recipe and I’m adding it to my rotation of favorite recipes. The Cauliflower is one of the most delicious things I’ve tasted in a while. I didn’t have time to make the pesto so I used a grocery store version and it was still amazing. When I have more time on a weekend I’ll make the real deal pesto. Thanks for the delicious recipe.
Hey Jen,

Hi! I just made this and it is so easy and delicious for a weeknight meal. I didn’t have smoked paprika so used a mix of aleppo pepper and sumac and was bummed when I went to my cheese drawer that i was out of parmesean so I used feta instead. Still came out good but I think the parm would have brought it all together for me!
Hey Lindsey,
I am thrilled that you enjoyed the recipe, thanks so much for making it! xTieghan
This was really tasty! I love making homemade pesto and this version was really good. I used toasted pine nuts & toasted pumpkin seeds. I added grilled chicken (marinated in the pesto) to the top of the pasta. We really enjoyed this. Your recipes are ALWAYS fantastic; I haven’t found a bad one yet! xoxox
Hey Amy,
I am so thrilled that you enjoyed the recipe, thanks so much for making it! Have a great week:) xTieghan
Made this for dinner tonight and accidentally ate most of the planned leftovers, it was so good. A quick, nourishing & delish meatless dinner. I made the pesto yesterday to save time & that worked well, too. Bravo!
Hey Christine,
I am so glad you enjoyed the recipe, thanks so much for giving it a try! Have a great week:) xTieghan
This was delicious! I substituted the pasta with Zucchini noodles for myself! Super healthy and everyone loved it! Really easy to prepare!
Hey Alyssa,

This recipe was perfect for the last cauliflower in our greenhouse! So good and easy. I used frozen basil (frozen in little blocks, with olive oil) from last summer — tasted as good as fresh. The lemon and jalapeno really made the pesto special.
Hey Mary,
I am so glad you enjoyed the recipe, thanks so much for giving it a try! Have a great week:) xTieghan
This is delicious! I kept going back for more cauliflower but the pesto is creamy and super tasty too. The coconut milk is the perfect end to this dish. Will be putting this on my meal rotation for sure!
Hey Maggie,
I am so glad you enjoyed the recipe, thanks so much for giving it a try! Have a great week:) xTieghan
This was delicious!
Thanks so much Megan! xTieghan
Very simple and easy recipe, loved it! I tried it with store-bought pesto the second time around but the one in the recipe has a lot more flavor in it. I subbed regular milk the first time around since I have a coconut allergy and it was goo, but when I used some heavy cream instead for the second time it was much better-i added small amounts of cream till the sauce was right. The cauilflower was delicious too, never though to add lemon juice and zest to roasted cauliflower.
Hey Vive,
I am so glad you enjoyed the recipe, thanks so much for giving it a try! Have a great week:) xTieghan
This was my first time making pesto and it was excellent even though I my local grocery store did not have basil. I used spring mix and pecans. Next time I hope to try it with the basil. I also really enjoyed the cauliflower. I will definitely make this again!
Hey Dena,
I am so glad you enjoyed the recipe, thanks so much for giving it a try! Have a great week:) xTieghan
I made this tonight! I wanted to make a double recipe of pesto to freeze, but didn’t have quite enough basil so used mint to make up the difference and it was fantastic (I didn’t have jalapeño so I put a dash of ancho chili powder, and left out the nuts bc my husband is allergic). The best part really was the cauliflower – I was worried it would be too much smoked paprika but it was perfect, and the lemon zest tossed on near the end lifted the flavor. I also roasted some mushrooms that were going to go bad with the same smoked paprika/garlic/lemon and it was great. My toddler ate his whole bowl of pasta with “dinosaur sauce” and declared it to be yummy.
Hey Shari,
I am so glad you enjoyed the recipe, thanks so much for giving it a try! Have a great week:) xTieghan
Thank you Tieghan for such a great recipe. We love pesto but this is my new way to make it, the lemon, arugula and coconut milk are such a good combination and the cauliflower is a tasty addition.
Hey Doreen,
