This tuna casserole recipe combines canned tuna, cheese, and a creamy sauce to create a healthy and filling weeknight dinner.
Preheat the oven to 180C/350F. Grease a large baking dish.
In a mixing bowl, add the drained tuna and flake it with a fork. Add the mayonnaise, sour cream, salt, pepper, smoked paprika, green onions, and Dijon mustard. Mix until smooth. Add the cauliflower then fold through the mozzarella cheese.
Transfer the mixture into the greased baking dish and top with gruyere cheese.
Bake the tuna casserole for 15-20 minutes, or until the cheese is golden brown.
