Ingredients
 

For the Zoodles:

  • 3 medium zucchini, spiralized

For the Cheese Sauce:

  • 1 tablespoon butter
  • 1 teaspoon garlic
  • 1 cup unsweetened almond milk
  • 1/4 cup heavy cream
  • 3 ounces cream cheese
  • 1 cup shredded cheddar cheese
  • 1 12 ounce can of tuna in water, drained

For the top:

  • 1/2 cup cheddar cheese
  • 1/2 cup mozzarella cheese

Equipment

  • Brieftons 5-Blade Spiralizer (BR-5B-02): Strongest-and-Heaviest Duty Vegetable Spiral Slicer, Best Veggie Pasta Spaghetti Maker for Low Carb/Paleo/Gluten-Free, With Extra Blade Caddy & 4 Recipe Ebooks

Instructions
 

  • Preheat oven to 350 degrees F.
  • Lightly spray the bottom of a 9x13-inch baking dish with cooking spray.
  • Place the zoodles in the dish and spread out as much as possible.
  • Bake zoodles at 10-minute intervals. Remove and stir every 10 minutes, continue baking at 10-minute intervals until the moisture has evaporated. **(see note below)
  • While zoodles are pre-baking, heat a medium size skillet over medium heat. Melt the butter, then add the garlic, almond milk, heavy cream, cream cheese and 1 cup of the cheddar cheese. Whisk mixture until it is smooth and cheese has melted.
  • Stir in drained tuna. Remove from heat.
  • In the 9x13-inch pan you pre-baked your zoodles in, layer the zoodles, tuna cheese sauce, and remaining shredded cheese to the top.
  • Bake 25-30 minutes until gold and bubbly.

Notes

  • Zoodles: Depending on the size and moisture level of the zucchini this may take between 10-20 minutes. Remove when moisture as evaporated and they have shrunk in size, but before they are brown or crispy.
  • Shredded chicken works great also if you want to switch things up!
