Add the two cans of tuna and 2 tablespoons of tomato paste mixed with one ladle of potato broth.

Mix well and cook for two to three minutes on low heat.

Step 3: Assemble the Casserole

Preheat your oven to 375°F (190°C).

Add half of the mashed potatoes to the bottom of a casserole dish and spread it out evenly.

Layer half of the tuna mixture over the mashed potatoes.

Add the remaining mashed potatoes over the tuna, followed by the remaining tuna mixture.

Top with 1/4 cup of shredded Parmesan cheese.
