  1. Preheat your oven to 375°F (190°C) and grease a 2-quart casserole dish.
  2. Cook the pasta according to the package instructions until it’s just shy of al dente. You want it slightly undercooked since it will continue cooking in the oven. Drain the pasta and set it aside.
  3. In a large skillet, melt the butter over medium heat. Add the diced onion, celery, and, if using, sliced mushrooms. Sauté them until they become tender and the onions turn translucent.
  4. Stir in the flour and cook for 1-2 minutes until the mixture becomes lightly golden, stirring constantly.
  5. Gradually whisk in the milk and chicken or vegetable broth to create a smooth sauce. Continue to cook and stir until the sauce thickens.
  6. Season the sauce with garlic powder, dried thyme (if using), and a pinch of salt and black pepper to taste.
  7. In a large mixing bowl, combine the cooked pasta, flaked tuna, thawed peas, and shredded cheddar cheese. Pour the creamy sauce over this mixture and gently fold everything together.
  8. Transfer the mixture into the greased casserole dish and spread it out evenly.
  9. Sprinkle the crushed potato chips over the top.
  10. Bake in the preheated oven for 25-30 minutes or until the casserole is bubbling, and the top is golden brown and crispy.
  11. Remove from the oven and let it cool for a few minutes before serving.
  12. Serve your Tuna Casserole hot and relish the comforting blend of flavors!
