Ingredients

• 4 cups Zucchini (spiralized into noodles or chopped into small cubes)
• 2 cans Canned tuna (in water, drained)
• 4 ounces Cream cheese
• 0.5 cup Heavy cream
• 1 cup Cheddar cheese (shredded)
• 0.5 cup Parmesan cheese (grated)
• 1 teaspoon Garlic powder
• 1 teaspoon Onion powder
• 0.5 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 tablespoon Olive oil (for sautéing)
• 2 tablespoons Chopped parsley (for garnish, optional)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

If using a spiralizer, spiralize the zucchini into noodle shapes. Alternatively, chop the zucchini into small cubes. Set aside.

Step 3

In a large skillet, heat the olive oil over medium heat. Add the zucchini noodles or cubes and sauté for 3-4 minutes until slightly softened. Drain any excess liquid and set aside.

Step 4

In the same skillet, add the cream cheese and heavy cream over low heat. Stir until the cream cheese is fully melted and combined with the cream to create a smooth sauce.

Step 5

Add the garlic powder, onion powder, salt, and black pepper to the sauce and stir well.

Step 6

Mix in the canned tuna, breaking up any large chunks with a spoon. Cook for 1-2 minutes to warm the tuna.

Step 7

Stir the sautéed zucchini into the tuna mixture until everything is well combined.

Step 8

Transfer the mixture to a lightly greased 8x8-inch baking dish and spread it out evenly.

Step 9

Sprinkle the shredded cheddar cheese and grated Parmesan cheese evenly over the top.

Step 10

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

Step 11

Remove from the oven and let the casserole cool for 5 minutes before serving.

Step 12

Garnish with chopped parsley, if desired, and serve immediately.
