Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch casserole dish and set aside.
Cook the egg noodles according to package instructions until al dente. Drain, rinse with cold water, and set aside.
In a large skillet, melt the butter over medium heat. Add the diced onion and cook for about 3 minutes until softened. Stir in the minced garlic and cook for an additional 30 seconds.
Add the sliced mushrooms to the skillet and sauté for 5-7 minutes, until the mushrooms are tender and their liquid has evaporated.
Sprinkle the flour over the mushroom mixture and stir well to coat. Cook for 1 minute to eliminate the raw flour taste.
Gradually whisk in the milk and chicken or vegetable broth, stirring constantly to create a smooth sauce. Bring to a gentle simmer and cook until the sauce has thickened, about 3-5 minutes.
Stir in the grated Parmesan cheese and season with salt and black pepper. Remove the skillet from heat.
In a large mixing bowl, combine the cooked noodles, creamy sauce, drained tuna, frozen peas, and 1 cup of shredded cheddar cheese. Mix well to evenly distribute the ingredients.
Transfer the mixture to the prepared casserole dish, spreading it out evenly. Sprinkle the remaining 0.5 cup of cheddar cheese over the top.
In a small bowl, combine the panko breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the casserole.
Bake the casserole for 25-30 minutes, or until the top is golden brown and the edges are bubbling.
Allow the casserole to cool slightly for 5 minutes before serving. Enjoy!
