Ingredients

• 4 cups Cauliflower rice
• 2 5-ounce cans Canned tuna (packed in water)
• 1.5 cups Cheddar cheese (shredded)
• 4 ounces Cream cheese (softened)
• 0.5 cups Heavy cream
• 1 teaspoons Garlic powder
• 1 teaspoons Onion powder
• 0.5 teaspoons Salt
• 0.25 teaspoons Black pepper
• 1 tablespoon Butter
• 2 tablespoons Fresh parsley (chopped)
• 0.5 cups Parmesan cheese (grated, for topping)

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x9-inch baking dish with butter or cooking spray and set aside.

Step 2

Heat a large skillet over medium heat and melt the butter. Add the cauliflower rice and sauté for 5-7 minutes, until it becomes slightly tender and most of the moisture evaporates.

Step 3

In a large mixing bowl, combine the softened cream cheese, heavy cream, garlic powder, onion powder, salt, and black pepper. Whisk until smooth.

Step 4

Drain the canned tuna and flake it with a fork. Add the cauliflower rice, tuna, and 1 cup of shredded cheddar cheese to the mixing bowl. Stir everything together until evenly combined.

Step 5

Transfer the mixture to the prepared baking dish and spread it out evenly.

Step 6

Sprinkle the remaining 0.5 cup of shredded cheddar cheese and the grated Parmesan cheese evenly over the top of the casserole.

Step 7

Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbly and golden brown on top.

Step 8

Remove the casserole from the oven and allow it to cool for 5 minutes. Garnish with fresh parsley before serving.
