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 Topping

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

Instructions
 

  • *Please watch recipe video for tips. Preheat oven to 350 degrees.
  • In an 9x13 baking dish lightly spray the bottom 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. **Depending on the size and moisture level of the zucchini this may take between 10-20 minutes. Remove when moisture has evaporated and they have shrunk in size, but before they are brown or crispy.**
  • While zoodles are pre-baking, heat a medium size skillet over medium heat. Melt the butter, 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 pan you pre-baked your zoodles in layer the zoodles, and tuna cheese sauce and remaining shredded cheese to the top. Bake 25-30 minutes until gold and bubbly.
