Ingredients:
- 225 g Wide Egg Noodles
- 2 x 142 g tins Quality Tuna packed in water or olive oil, thoroughly drained and flaked
- 120 g Frozen Sweet Peas
- 1 Large Shallot, finely minced
- 2 Celery stalks, finely diced
- 1 tsp Olive Oil
- 55 g Unsalted Butter (for roux)
- 55 g All-Purpose Flour
- 700 ml Whole Milk, warmed slightly
- 120 ml Chicken or Fish Stock (low sodium)
- 1 tsp Dijon Mustard
- 1/2 tsp Smoked Paprika
- 1/4 tsp Freshly Grated Nutmeg
- 1/4 tsp White Pepper
- 1 tsp Salt (or to taste)
- 30 g Aged Cheddar Cheese, grated (optional)
- 60 g Panko Breadcrumbs
- 2 Tbsp Unsalted Butter, melted (for topping)
- 30 g Grated Parmesan Cheese
- 1/2 cup Crispy Fried Onions
Instructions:
- Preheat the oven to 190°C (375°F). Grease the 9x13 inch casserole dish lightly.
- Cook Noodles: Bring salted water to a rolling boil. Cook the egg noodles until al dente (usually 1 minute shy of package instructions). Drain immediately and toss lightly with a drizzle of oil to prevent sticking. Set aside.
- Sauté Aromatics: In the saucepot, heat 1 tsp olive oil over medium heat. Add the minced shallot and diced celery. Sauté gently for 5-7 minutes until softened and translucent, but not browned. Remove vegetables and set aside, leaving the pot on the heat.
- Create the Roux: Reduce the heat to medium-low. Add the 55g butter to the pot. Once melted, whisk in the 55g flour. Cook the roux for 2 minutes, stirring constantly, until it smells slightly nutty and loses the raw flour smell (a light blonde roux).
- Build the Béchamel: Slowly pour the warmed milk into the roux, whisking vigorously the entire time to prevent lumps. Once smooth, stir in the stock.
- Simmer and Season: Bring the sauce to a gentle simmer, stirring frequently. Allow it to thicken to coat the back of a spoon (about 5-8 minutes). Remove from heat. Stir in Dijon mustard, paprika, nutmeg, white pepper, and salt. If using, stir in the grated Cheddar until melted and smooth. Taste and adjust seasoning.
- Combine Filling: Gently fold the cooked shallots and celery, the flaked tuna, and the frozen peas into the béchamel sauce.
- Fold in Noodles: Add the cooked noodles to the sauce mixture. Stir carefully until everything is evenly coated. Transfer the entire mixture to the prepared casserole dish.
- Prepare Topping: In a small bowl, combine the Panko, melted butter, Parmesan cheese, and crispy fried onions. Toss until coated.
- Top and Bake: Sprinkle the topping evenly over the casserole mixture. Bake for 25 minutes, or until the sauce is bubbly around the edges and the topping is golden brown and crisp.
- Rest: Remove from the oven and allow the casserole to rest for 10 minutes before serving. This crucial step allows the sauce to set properly.
