Ingredients

• 4 medium zucchini
• 2 cans (5 oz each) canned tuna
• 1 medium onion
• 2 pieces garlic cloves
• 2 tablespoons olive oil
• 8 ounces cream cheese
• 0.5 cup milk
• 1 cup shredded cheddar cheese
• 0.5 cup parmesan cheese
• 1 cup breadcrumbs
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 teaspoon dried oregano
• 0.5 teaspoon paprika

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Wash the zucchinis and slice them into thin, round discs of approximately 1/4-inch thickness. Set aside.

Step 3

Finely chop the onion and mince the garlic cloves.

Step 4

Heat the olive oil in a large skillet over medium heat. Add the onion and garlic, cooking until softened and fragrant, about 3-4 minutes.

Step 5

Drain the canned tuna and add it to the skillet, mixing to combine with the onion and garlic. Cook for 2 additional minutes. Remove from heat and set aside.

Step 6

In a small saucepan over low heat, melt the cream cheese and slowly whisk in the milk until the mixture is smooth. Stir in the shredded cheddar cheese, salt, black pepper, oregano, and paprika. Mix until well combined and creamy.

Step 7

Grease a 9x13-inch baking dish with nonstick spray or a thin coat of olive oil.

Step 8

Layer half of the sliced zucchini evenly along the bottom of the dish, overlapping slightly if necessary.

Step 9

Spread half of the tuna mixture over the zucchini in an even layer.

Step 10

Pour half of the cheese sauce over the tuna mixture, spreading it out gently with a spatula.

Step 11

Repeat the layers: a layer of zucchini, followed by the remaining tuna mixture, and the rest of the cheese sauce on top.

Step 12

In a small bowl, mix the breadcrumbs with the grated parmesan cheese. Sprinkle this mixture evenly over the top of the casserole.

Step 13

Place the dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the casserole is bubbling at the edges.

Step 14

Remove the dish from the oven and allow it to cool for 5-10 minutes before serving.

Step 15

Garnish with fresh parsley or a sprinkle of paprika if desired, and enjoy!
