A comforting and easy-to-make cheesy tuna pasta bake that is perfect for a family dinner.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
Cook the rotini pasta in a large pot of boiling salted water until al dente, then drain.
Cooking the pasta al dente prevents it from becoming mushy during baking.
In a mixing bowl, whisk together the softened cream cheese, milk, and mustard until smooth.
Ensure the cream cheese is fully softened for a smoother sauce.
Stir in the tuna, peas, and carrots into the sauce mixture.
Mix gently to avoid breaking up the tuna too much.
Combine the cooked pasta with the sauce mixture and transfer to a baking dish.
Mix thoroughly to ensure the pasta is evenly coated with the sauce.
Sprinkle the shredded cheddar cheese evenly over the top.
For a golden crust, use a mix of cheddar and Parmesan cheese.
Bake in the preheated oven for 30 minutes, or until the top is golden and bubbly.
Let the casserole rest for a few minutes before serving to set the layers.
Serve warm and enjoy your cheesy tuna pasta bake!
Garnish with fresh parsley for a pop of color and flavor.
