  • Preheat oven to 400 degrees + prepare a greased 9x13 oven safe dish
  • Fill a microwave safe glass dish with 1 inch of water. Slice spaghetti squash in half + place face down in water. Microwave on high for 10 minutes until cooked OR cook in instant pot following these directions.
  • While spaghetti squash is cooking, make shredded chicken. You can cook it in the instant pot, crockpot, or bring a pot of water to a boil on the stove. Cook the chicken in boiling water for 10 minutes + shred (You can also buy a rotisserie chicken + shred!)
  • While the chicken cooks, remove spaghetti squash from microwave + shred.
  • Once the chicken has cooked, pull it apart with forks to shred.
  • In a bowl, add shredded spaghetti squash, enchilada sauce, shredded chicken, beans, corn, green chiles.
  • Mix all ingredients until combined + place in a greased 9x13 oven safe baking dish. Top with cheddar cheese.
  • Bake at 400 for 20 minutes until the top starts to brown.
  • Serve + enjoy!



Chicken: You can use chicken thighs or even chicken tenders in place of chicken breasts.
Enchilada Sauce: Red or green enchilada sauce will work in this recipe.
Corn: We like to use frozen corn and defrost it but you can also use canned corned (drained and rinse it first!)
Black Beans: Pinto beans or kidney beans would work well in this recipe
Green Chiles: Green chiles are optional, but delicious! You can skip them if you don't have them on hand.
Cheese: You can use pepper jack, monterey jack or colby jack cheese in place of cheddar. We haven't tried it with low fat cheese but it would probably work.
Low Salt: If you're watching your sodium intake look for low salt enchilada sauce and salt free black beans. Cheese is naturally high in salt.
WW Note: The only points in this recipe are for the cheddar cheese. You can sub in low fat cheddar cheese and it will only be 1SP per serving on blue.
