Preheat oven to 400° F and line a baking sheet with parchment paper.
Cut the squash in half by cutting lengthwise. NOTE: This is the hardest step. Make sure you have a steady surface and a sharp knife.
Scoop out the seeds.
Cover the entire squash halves with olive oil using a pastry brush or your hands. Sprinkle with salt and pepper and place flat side down on the baking sheet.
Bake for 45 min-1 hour or until the squash is tender.
Remove from the oven and let the squash cool before shredding. Make sure to keep the empty shells to refill.
Twice Baked Instructions
Pan-fry your diced chicken. Once the chicken is browned, remove to a separate plate.
Sauté the broccoli, minced garlic, Italian seasonings, salt, and pepper for about 3-4 minutes.
Add the chicken back to the pan and finish cooking the chicken and broccoli.
Transfer the chicken and broccoli to a large mixing bowl. Add the shredded squash strands and add ¾ alfredo sauce. Mix until fully coated.
Transfer the alfredo mixture back into the empty shells/"boats" and top with the remaining alfredo sauce and Mozzarella cheese. Place the "boats" in a baking dish to cook.
Set oven to 350° F and cover the baking dish with foil. Create a tent to prevent the foil from touching the cheese.
Bake for 15 minutes. Remove the foil and broil for 1-2 minutes until your cheese is crunchy and browned.
