Instructions:

Cook the Pasta

  1. Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.
  2. Cook the gluten-free pasta according to the package instructions until al dente.
    Drain and set aside.

Make the Creamy Sauce

  1. In a large bowl, combine:
    a. Gluten-free cream of mushroom soup
    b. Milk
    c. Garlic powder, onion powder, salt, and pepper

Mix it All Together

  1. Stir in the drained tuna, frozen peas, and cooked pasta until evenly coated.

Assemble the Casserole

  1. Pour the mixture into the prepared baking dish and spread it evenly.
  2. Sprinkle the shredded cheddar cheese on top.

Add the Topping

  1. In a small bowl, mix gluten-free breadcrumbs with melted butter.
  2. Sprinkle the breadcrumb mixture evenly over the cheese layer.

Bake the Casserole

  1. Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and
    the breadcrumbs are golden brown.
  2. Allow it to cool for 5 minutes before serving.

Serve and Enjoy
Garnish with fresh parsley and serve warm. This casserole pairs well with a simple green
salad or roasted vegetables.
