Ingredients:
- 12 oz Wide Egg Noodles
- 1 Tbsp Kosher Salt (for boiling water)
- 3 Tbsp Unsalted Butter
- 1 small Shallot or Small Yellow Onion, finely diced
- 1/4 cup All-Purpose Flour
- 2 cups Whole Milk, warmed
- 1 cup Low-Sodium Chicken or Vegetable Stock
- 1 tsp Dijon Mustard
- 1/2 tsp Garlic Powder
- Salt and Freshly Ground Black Pepper (to taste)
- 4 oz Sharp White Cheddar Cheese, grated
- 2 oz Parmesan or Gruyère, grated (optional)
- 2 x 5 oz cans Tuna, packed in olive oil, drained
- 1 cup Frozen Sweet Peas
- 1 cup Panko Breadcrumbs
- 2 Tbsp Unsalted Butter, melted (for topping)
- 1/4 cup Sharp Cheddar Cheese, grated (for topping)
Instructions:
- Preheat the oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish. Boil the egg noodles in heavily salted water until al dente (usually 1-2 minutes less than package directions). Drain immediately and set aside; do not rinse.
- Melt the 3 Tbsp butter in a heavy-bottomed saucepan over medium heat. Add the diced shallot/onion and sauté gently until translucent and softened, about 3-4 minutes. Sprinkle the flour over the softened shallots and whisk constantly for 1 minute to cook the roux.
- Gradually whisk in the warm milk and stock, pouring slowly to avoid lumps. Bring the mixture to a gentle simmer, whisking frequently until the sauce thickens significantly (it should coat the back of a spoon).
- Remove the saucepan from the heat. Stir in the Dijon mustard, garlic powder, and a generous pinch of salt and pepper. Add the 4 oz of grated cheddar and the optional Parmesan/Gruyère. Stir until completely melted and the sauce is smooth and glossy. Taste and adjust seasoning.
- Gently fold the cooked noodles, drained tuna, and frozen peas into the cheese sauce until everything is evenly coated. Pour the mixture into the prepared casserole dish, spreading evenly.
- In a small bowl, combine the Panko breadcrumbs, 2 Tbsp melted butter, and 1/4 cup of grated cheddar. Toss until evenly moistened. Sprinkle the breadcrumb mixture evenly over the pasta bake.
- Bake for 25 minutes, or until the sauce is visibly bubbling around the edges and the topping is deeply golden brown and crispy.
- Remove from the oven and let the bake rest for 5–10 minutes before serving. This allows the sauce to set slightly, making serving neater.
