I didn’t grow up on homemade mac and cheese. Actually I have never had it until I was an adult and boy was it good. I’m not talking about the kind that comes in a box, I mean the rich and cheesy baked macaroni with crusty top.
With that in mind I came up with this low carb mac and cheese with shrimp recipe. It rich and cheesy and is crusty and delicious on top. I didn’t use pasta of course but I did use yellow squash! It turned out great. With the succulent shrimp it was a very filling but delicious dinner.
What Is The Low Carb Macaroni Substitute?
I used yellow squash instead of macaroni in this recipe because it seems to have less liquid than green zucchini and it’s a break from the usually cauliflower. But mostly I used it because I thought if I cut it up using a melon ball tool it would have the texture of a shell pasta. And it sort of does except it does have the chew of pasta. Still I felt it was a good substitute.
I scooped it out quickly so it’s not very uniform (I was in a hurry) but I wanted it to have a crescent moon shape. I will take more time with it next time. And there will be a next time because it was really yummy!
Where I Bought The Ingredients
I wanted to mention that I bought everything for this dish at Aldi. I LOVE their frozen jumbo raw shrimp. They are very tasty and succulent when cooked. I also bought one of their fancy mature cheddar cheese, yellow squash, pork rinds, grated parmesan, heavy cream and butter. So if you have an Aldi nearby you can grab all of these at a very good price.
Low Carb Mac And Cheese Recipe
- Cut the squash, using a melon ball tool.
- In a large bowl, beat the egg and mix in the cream and cheddar cheese.
- Fold in the squash and shrimp.
- Spoon everything into a baking dish.
- Top with a mixture of crushed pork rinds and parmesan cheese.
- Chop up a little butter and scatter along the top like the picture below.
- Bake in a350 degrees F for 40 minutes.
Below you can see what it looks like coming out fo the oven. It still has a little liquid from the squash but it’s not much. I made this both with and without shrimp and both were delicious. So don’t fret if you don’t have any shrimp on hand.
What Other Low Carb Vegetables Can I Use?
I use yellow squash but you can also use the following vegetables to mimic pasta in this low carb recipe and here is a nice article from the Diet Doctor:
- cauliflower florets
- spaghetti squash

- celeriac or celery root
- delicata squash
