Ingredients Method Notes

Ingredients
  

  • The Pasta: 12 oz 350g Penne, Fusilli, or Rigatoni.
  • The Protein: 2 cans 5 oz each Tuna (drained and flaked).
  • Vegetables: 1 cup frozen peas 1 small red onion (finely diced), 1 stick of celery (finely chopped).
  • The Sauce Base: 3 tbsp unsalted butter 3 tbsp all-purpose flour, 2 cups whole milk.
  • Cheese & Zest: 1.5 cups sharp Cheddar shredded, juice and zest of ½ lemon.
  • Seasoning: 1 tsp Dijon mustard ½ tsp garlic powder, salt, and black pepper to taste.
  • The Crunch: ½ cup Panko breadcrumbs mixed with 1 tbsp melted butter and 1 tbsp dried parsley.

Method
 

  1. Boil the Pasta: Preheat your oven to 200°C (400°F). Cook the pasta in a large pot of salted water for about 2 minutes less than the package instructions (it should be slightly too firm to eat). Drain and set aside.
  2. Sauté Aromatics: In a large saucepan, melt the butter over medium heat. Add the onion and celery, cooking for 3–4 minutes until soft.
  3. Create the Sauce: Whisk the flour into the butter and cook for 1 minute. Gradually pour in the milk, whisking constantly until the sauce thickens and coats the back of a spoon.
  4. Flavor and Melt: Stir in the Dijon mustard, garlic powder, lemon zest, lemon juice, and 1 cup of the Cheddar cheese. Whisk until the cheese is melted and the sauce is glossy.
  5. Combine: Fold the cooked pasta, drained tuna, and frozen peas into the cheese sauce. Stir gently so you don't break the tuna chunks too much. Season with salt and pepper.
  6. The Bake: Pour the mixture into a greased baking dish. Top with the remaining ½ cup of Cheddar and the buttery Panko breadcrumbs. Bake for 15–20 minutes until the top is bubbling and deep golden brown. The photograph shows the dish before the topping.

Notes

Chef’s Tips
The Tuna Trick: Use tuna canned in olive oil if you want an even richer flavour but be sure to drain it well so the pasta bake doesn't become greasy.
Avoid the Mush: Since the pasta continues to cook in the oven, boiling it to "al dente" in the pot usually results in overcooked noodles. Aim for "molto al dente" (very firm) before draining.
Veggie Variations: If peas aren't your favourite, swap them for canned sweetcorn, sautéed mushrooms, or chopped baby spinach for an extra nutrient boost.
