How to Make Low-Carb Crockpot Spaghetti & Meatballs

Prepare the Spaghetti Squash & Meatballs: Place the spaghetti squash in the microwave for about 5 minutes to soften. In a bowl, mix the ground meat, egg, Italian seasoning, almond flour (or regular flour), salt, and pepper. Set the mixture aside.

3

Add the Meatballs: Roll the meat mixture into meatballs and arrange them around the spaghetti squash in the crockpot.

Cook & Serve: Cook on low for 6 hours or on high for 3 hours. Once done, use a fork to scrape the spaghetti squash into noodle-like strands and serve with the meatballs and sauce.
