    Spaghetti Squash Shrimp Alfredo

    Spaghetti squash shrimp alfredo is my favorite way to enjoy a spaghetti squash. You can make them in so many different ways with a variety of sauces, but this one always brings me back. The spaghetti squash is the perfect vessel to hold the light "noodles", creamy sauce, plump shrimp, and cheesy crust. 

    Not to be confused with the butternut squash which is also a winter vegetable, the spaghetti squash is the only one that can create the strands needed for the pasta hence the name. Of course there are butternut squash noodles like there are zucchini noodles, but they require a tool to create the noodles. It's the perfect time to give it a try because they are in season now.

    Good news with this recipe is that it's a healthy pasta alternative for those of you that are on a low carb diet. The bad news is this is not a healthy food recipe with all the cream and cheeses. I can guarantee that this is a delicious recipe and will be made over and over again. 

    Spaghetti Squash Alfredo Ingredients

    Spaghetti Squash- The size of your squash will depend on what half of it would be the perfect serving size for a person. I tend to go more on the smaller side.

    Shrimp- I use large shrimp, approximately 12. You can use a smaller size so you have more shrimp in every bite.

    Heavy Cream- This is used to make the homemade alfredo sauce.

    Cheese- Parmesan cheese is used in the sauce and mozzarella cheese is used for the topping.
