You guys? This Cheesy Pesto Zoodles recipe is going to Make. Your. Week. I’m not even kidding. So creamy and cheesy that even your picky family members will be on board with this vegetarian friendly keto zucchini recipe!

Hearty enough to enjoy on its own as a main dish, this cheesy pesto zoodles recipe also makes a fantastic side dish to break up your weeknight monotony of protein + cheesy cauliflower puree. (Just kidding, I still love you Cheesy Cauliflower Puree!)
Seriously though, you can add some cooked chicken or sausage to these cheesy keto zucchini noodles and it will be even more fantastic!

That being said, I’m working on more meatless keto recipes for the blog, which will no doubt be an exciting development to those of you trying to follow a vegetarian keto diet, but for the rest of you don’t panic – I’m not going full veggie on you anytime soon.
Just going to sprinkle some more vegetarian friendly keto recipes into my regular feed here. But if you haven’t tried it yet, this Cheesy Pesto Zoodles recipe is the perfect place to start!

Another thing to love about this cheesy pesto zoodles recipe is that it can be made in just minutes. And I’m not trying to get you on a technicality here–like how people will say minutes but it’s 59 minutes, so really an hour. It literally takes minutes (less than 20 of them) to have this zucchini noodle recipe on the table from start to finish!
So when you get home from work and you’re starving–but also Netflix, jammies, and your couch are calling? Tell them you’ll be right there and make these cheesy pesto zoodles STAT.
Recipe Notes:
- You will need a veggie spiralizer to make the zucchini noodles for this recipe, and you can get them for around $30 on Amazon. For convenience sake, you can purchase pre-spiralized zucchini noodles in the produce department of some grocery stores.
- You can use home-made or store-bought basil pesto for this cheesy pesto zoodle recipe, but it also tastes amazing with my garlic scape pesto.

Notes
Net carbs = 5g per serving.
*Don’t try to add the mozzarella to the other cheeses when microwaving or you’ll have a hard time getting the mascarpone to create a smooth sauce. Also adding it just before baking gets lots of epic cheese pull when you’re eating it which is very gratifying.
**If you don’t own a microwave, you can steam the zucchini noodles and then drain any excess liquid before adding to the sauce. The sauce will cook on the stovetop in about 5 minutes over medium heat.
(And no, I really don’t want to read your 1127 page manifesto on the evils of the microwave so I beg of you, please don’t email me or rail in the comments. TIA.)

My husband and I love this! I made this last night for the two of us to have as a side with steak and it was great! Since there is just the two of us we had leftovers – tonight I folded in some chicken with the noodles and warmed up in the oven, tastes like Chicken Alfredo – lovely! Thank you for all you do on your blog. I am new here and to the world of keto / low carb and your recipes and videos are a treasure, I have already shared your site with many of my coworkers and my son.

I really want to try this recipe!! Thanks for posting this. It looks fantastic.
Also, this snarky side note made me laugh out loud at work: “(And no, I really don’t want to read your 1127 page manifesto on the evils of the microwave so I beg of you, please don’t email me or rail in the comments. TIA.)” I see that ALL the time on recipes that involve using a microwave and it’s so dumb. You don’t have to use it if you don’t want to! There are so many alternative ways of melting butter or steaming veggies lol.

Mascarpone where have you been all my life!!! This was awesome!! Being new to the low carb/Keto lifestyle I am so glad I found your site!! I am also following week 1 of the weekly meal plan. Thank you
Diane Kerper says
This recipe sounds awesome. How would you adjust the recipe if you were bringing this to someone’s house? Would you bake it in advance and cool and refrigerate it and then reheat it when you get to where you’re going? Or just assemble everything in the dish and do the baking right before you’re going to eat it?

I added two cans of tuna and it was great. It reminded me of cheesy tuna casserole from childhood. :)
Kristi says
This was amazing! My 8 yr old loved it! He said it was fantastic and was a little upset I only made 2 servings. ?
Daisy says

Michael Kagan says
Is the serving size 1/2 a cup or 1.5 cups?
Michael Kagan says
Never mind I figured it out. It was formatted weird on my phone.
Bethany Eder says
