Kraft Mac and Cheese Tuna Casserole: A comforting casserole that blends the creamy, cheesy goodness of Kraft mac and cheese with hearty tuna for a satisfying meal.

Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish with nonstick spray.

Bring 6 cups of water to a boil in a medium saucepan. Add the macaroni from the box and cook for 7 minutes. Drain the macaroni, rinse with cold water, then drain again. Set the cheese sauce packet aside.

In the same saucepan, melt butter over medium heat. Add the milk and the cheese sauce packet, stirring to combine. Add the condensed soup and heat the mixture for about 3 minutes until well blended.

In a large bowl, mix the drained macaroni, peas, and tuna. Stir in the creamy soup mixture. Pour everything into the prepared baking dish.

Bake the casserole in the preheated oven for 30 minutes. Then sprinkle Cheddar cheese on top, followed by a layer of French-fried onions. Return to the oven and bake for an additional 5 minutes, until the onions are golden and the cheese has melted.
