Million Dollar Spaghetti Recipe: Adapted to Be Low Carb

If you’ve been drooling and sighing over those Pinterest pictures of Million Dollar Spaghetti? you’re in luck – because I’ve made adapted it for low carb. All of the gooey cheesy goodness, all of the rich meat sauce, all of the delicious satisfaction but only 6 net carbs per generous serving. It’s easy to make, budget friendly, and it freezes relatively well so you can make it once and have leftovers another time. Spiralized zucchini stands in for the pasta in this recipe but look for variations in the recipe notes below.

For this recipe you’ll need: zucchini, butter, Mozzarella cheese, cream cheese, whole milk ricotta, ground beef, marinara (look for lowest carb? version I used Bertolli with 8 carbs per 1/2 cup)

I don’t know about you but I spend a good amount of my non-existent free time drooling over food images on Pinterest. Sadly, the images that look the best to me are almost NEVER low carb. So, I save them to a secret board to try to recreate them with low carb ingredients. Sometimes it works beautifully and sometimes I end up with a mess. Luckily this time I ended up with a yummy low carb version of million dollar spaghetti made with zoodles.

I was worried that the zucchini noodles would get too mushy so I just blanched them for a minute in boiling water then plunged them into ice water to stop the cooking. It worked well. Next time I am going to try making the casserole without cooking the zoodles in any way to see if the oven gets them done enough.

Y’all, this came out so creamy and yummy that I was practically swooning when I tried it.

Recipe Notes

This dish is absolutely perfect as is but here are some variations that are good – plus just some tips you’ll want to know. As always, when using the variations remember to change the nutrition information and always watch for extra carbs.


  • Try Cheddar in place of the Mozzarella and use taco meat and enchilada sauce instead of the ground beef and marinara.
  • Add slices of pepperoni on top of the cheese layer.
  • Use ground turkey instead of beef.
  • Stir in some Gorgonzola to the cheese sauce.
  • Use another firm vegetable instead of zucchini for spiralizing – Turnip? Jicima? Broccoli stems?
  • Steamed cauliflower can be used in place of the zoodles.


This casserole was so easy to make but there are a couple of things that made it even better.

  • The zucchini releases a lot of water during baking. To counteract this if you have time salt the zoodles and let them sit in a colander to drain for an hour. Rinse the salt off well before using.
  • Pat the zucchini dry with paper towels before adding to the casserole pan.
  • Use spaghetti squash in place of the zoodles.
  • I liked the fat content of using 80/20 beef but you can use 90/10 if you want.
  • The cooking is just for heating purposes since everything is cooked before it goes into the casserole. To keep the zucchini from overcooking you can forego the oven and heat it in the microwave.

This is not a beautiful dish but it IS a delicious one!

Thanks so much for being a part of Lowcarb-ology!

I got a spiralizer attachment for my Kitchen Aid for Christmas and I have to tell you I LOVE IT. It is definitely a change from buying pre-zoodled zoodles and I was never able to get the manual ones to work.

  1. I have a question – for the zucchini zoodles, could I use the frozen ones? If so, would I have to cook them longer?

    Thanks, Cindy
