Ingredients:
- 8 oz medium-width Egg Noodles
- 2 (5 oz) cans Tuna packed in water or olive oil, well drained
- 1 cup Frozen Sweet Peas (do not thaw)
- 4 Tbsp Unsalted Butter (for sautéing and the roux)
- 1/2 cup Yellow Onion, finely diced
- 1/2 cup Celery stalks, finely diced
- 1/4 cup All-Purpose Flour
- 2 cups Whole Milk (or Half-and-Half)
- 1/2 cup Low-Sodium Chicken Stock or Vegetable Stock
- 1 tsp Dijon Mustard
- 1 tsp Worcestershire Sauce (optional)
- 1 cup Sharp Cheddar Cheese, grated
- Salt and Freshly Ground Black Pepper, to taste
- 1/2 cup Panko Breadcrumbs
- 2 Tbsp Unsalted Butter, melted
- 1/4 cup Parmesan Cheese, grated
Instructions:
- Preheat your oven to 375°F (190°C). Lightly grease the 9x13 inch casserole dish.
- Bring a large pot of salted water to a boil. Cook the egg noodles according to package directions, undercooking by about 2 minutes (they will finish cooking in the oven). Drain well and set aside.
- In the large saucepan, melt the 4 Tbsp of butter over medium heat. Add the diced onion and celery. Sauté gently for 5–7 minutes until the vegetables are softened and translucent.
- Sprinkle the flour over the softened vegetables. Cook, stirring constantly, for 1–2 minutes to create the roux and remove the raw flour taste.
- Slowly whisk in the milk until the sauce is smooth and lump-free. Then, whisk in the chicken stock. Bring the mixture to a gentle simmer, stirring frequently, until the sauce thickens significantly (it should coat the back of a spoon). Remove the pan from the heat.
- Stir in the Dijon mustard, Worcestershire sauce, salt, and pepper. Add the grated Cheddar cheese and stir until completely melted and smooth. Taste and adjust seasoning as needed.
- Add the drained, cooked noodles, the well-drained tuna, and the frozen peas directly into the cream sauce. Gently fold all the ingredients together until everything is evenly coated in the sauce.
- Pour the mixture into the prepared casserole dish, spreading it into an even layer.
- In a small bowl, combine the Panko breadcrumbs, the 2 Tbsp of melted butter, and the grated Parmesan cheese. Toss until the breadcrumbs are saturated.
- Sprinkle the topping evenly over the noodle mixture. Bake for 25–30 minutes, or until the sauce is bubbling around the edges and the topping is deeply golden brown.
- Remove from the oven and let rest for 5–10 minutes before serving.
