Tuna Noodle Casserole

This Tuna Noodle Casserole combines tender egg noodles with a creamy sauce made from sautéed onions, mushrooms, milk, cream cheese, and broth. Peas and tuna add bursts of flavor and protein, while a Parmesan breadcrumb topping creates a subtle crisp contrast. The slow simmer and sauce thickening result in a hearty, comforting dish with a balanced blend of textures.

Instructions

    Cup of Yum
  1. Finely dice the onion and add it to a skillet with 1 Tbsp butter. Sauté the onion over medium heat until softened.
  2. While the onion is cooking, slice the mushrooms. Add them to the skillet with the onion and ¼ tsp each of salt and pepper. Continue sautéing over medium heat until the mushrooms have softened. Remove the mushrooms and onions from the skillet and set aside.
  3. Add the flour and an additional 2 Tbsp butter to the skillet. Cook and whisk over medium heat as the butter melts. Continue whisking as the butter and flour bubbles and foams for about one minute.
  4. Add the milk, broth, and cream cheese to the skillet. Whisk to combine with the butter and flour mixture. Continue cooking over medium, whisking until the cream cheese has fully melted in and the sauce begins to simmer, at which point it will thicken.
  5. Add the frozen peas and the cooked mushrooms and onions back to the sauce. Stir to combine, then season with more salt and pepper (about ½ tsp salt and another pinch of pepper). Set the sauce aside.
  6. Begin to preheat the oven to 350ºF. Bring a large pot of water to a boil for the noodles. Once boiling, add the egg noodles and boil for about 7 minutes, or just until tender. Drain the noodles in a colander.
  7. While the noodles are boiling, prepare the breadcrumb topping. Melt 1 Tbsp butter, then stir in the breadcrumbs and Parmesan.
  8. Combine the creamy mushroom sauce, cooked and drained noodles, and drained tuna.
  9. Transfer the casserole mixture to a 3 quart casserole dish, then top with the breadcrumb topping.
  10. Bake the casserole for about 25 minutes or until heated through and golden brown on top. Serve hot and enjoy!
