How to Make No-Soup Tuna Noodle Casserole

Ingredients:

  • Fine salt (as needed)
  • 8 ounces broad egg noodles
  • 4 tbsp unsalted butter, more as needed
  • 8 ounces mushrooms (sliced)
  • 3 tbsp all-purpose flour
  • 2 1/2 cups milk
  • 1/2 cup mayonnaise
  • 1 1/2 cups frozen peas (thawed)
  • 2 (5- to 6-ounce) cans of tuna in water, drained and flaked
  • 2 to 3 tbsp coarsely chopped pimientos (drained)
  • 1 cup breadcrumbs (soft, fresh)
  • 2 tbsp unsalted butter (melted)
  • 1/4 tsp fine salt (more to taste)
  • 1 tbsp finely chopped fresh parsley (for garnish, optional)

Directions:

  1. Prepare the oven and cook the noodles: Preheat your oven to 350°F (180°C). In a large pot, bring salted water to a boil and cook the egg noodles until they are al dente. Drain and rinse the noodles with cold water to stop the cooking. Set them aside.

  2. Sauté the mushrooms: In a large saucepan, melt some unsalted butter over medium heat. Add the sliced mushrooms and sauté until they are golden brown and tender.

  3. Make the roux: Sprinkle the flour over the cooked mushrooms and stir continuously for about 1-2 minutes, allowing it to develop a nutty aroma.

  4. Create the sauce: Slowly whisk in the milk, continuing to stir until the sauce thickens.

  5. Incorporate the remaining ingredients: Mix in the mayonnaise, thawed peas, flaked tuna, and chopped pimientos. Season everything with salt to taste, and let it simmer for 1 minute while stirring.

  6. Combine and transfer to baking dish: Add the cooked noodles to the sauce and stir until everything is well combined. Transfer this mixture into a lightly buttered 2-quart baking dish, spreading it evenly.

  7. Prepare the topping: In a small bowl, combine breadcrumbs, melted unsalted butter, and a pinch of salt until you have a nice mixture.

  8. Bake and serve: Sprinkle the buttered breadcrumb mixture evenly over the casserole. Bake for about 25 minutes or until it’s bubbly and the topping is golden brown. If desired, garnish with parsley and serve hot.
