  • Total Time: 1 hour 15 minutes
  • Yield: 4 1x

Ingredients

Scale
  • 1 medium spaghetti squash
  • 1 tablespoon olive oil
  • 1 cup cooked chicken ham, diced
  • 1/2 cup cooked turkey bacon, crumbled
  • 1 cup shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 1/2 cup heavy cream or unsweetened plant-based cream
  • 2 cloves garlic, minced
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon paprika
  • 2 tablespoons chopped fresh parsley

Instructions

  1. Preheat the oven to 400°F (200°C).
  2. Cut the spaghetti squash in half lengthwise and remove the seeds.
  3. Brush the cut sides with olive oil and season with salt and pepper.
  4. Place cut-side down on a parchment-lined baking sheet and roast for 35-40 minutes, until tender.
  5. While roasting, prepare the cheese sauce: combine heavy cream, minced garlic, and cheddar cheese in a saucepan over medium heat. Stir constantly until smooth.
  6. Add Parmesan cheese, paprika, and additional salt and pepper. Remove from heat.
  7. Cook turkey bacon in a skillet until crisp, then crumble. Dice chicken ham into small pieces.
  8. Scrape the roasted squash into strands with a fork and place in a large mixing bowl.
  9. Mix in chicken ham, turkey bacon, and half of the cheese sauce until evenly coated.
  10. Transfer the mixture to a greased baking dish.
  11. Pour the remaining cheese sauce over the top and sprinkle with parsley. Optionally, add extra cheese for a golden crust.
  12. Bake at 375°F (190°C) for 20-25 minutes until the top is lightly browned.
  13. Let rest for 5 minutes before serving.

Notes

You can substitute cheeses or add vegetables like spinach or mushrooms.

Prepare components ahead of time for convenience; assemble and bake just before serving.

Freezing is possible, but fresh preparation yields the best texture.
