🛒 Ingredient notes

Pasta – Choose a short pasta like penne, rigatoni or fusilli so the sauce clings to each piece.
Tuna – Tinned tuna in spring water gives a lighter result; tuna in oil will be richer. Drain well before adding.
Cheese sauce – Make a simple béchamel with butter, flour and milk, then stir through grated extra-mature cheddar plus a touch of Dijon mustard and smoked paprika for depth.
Sweetcorn – Tinned or frozen both work. If using frozen, add it to the pasta water for the last 5 minutes of cooking.
Sun-dried tomatoes – Optional for extra colour and a sweet, tangy note.
Parmesan – A sprinkle of grated Parmesan before baking gives a golden, crisp topping.
Herbs – Finish with chopped parsley or basil for freshness.
🔪 How to make creamy tuna sweetcorn pasta bake
The recipe card with ingredient quantities and detailed instructions is below.
One: Bring a large pot of salted water to a boil and cook the pasta until al dente. If using frozen sweetcorn, add it 5 minutes before the pasta finishes. Reserve a cup of the cooking water, then drain the pasta.
💡Pro Tip: If you prefer tinned sweetcorn, stir it into the finished cheese sauce instead of boiling it with the pasta.
Two: Melt the butter in a saucepan over medium heat, whisk in the flour and cook for about 1 minute to form a roux.
Three: Gradually whisk in the milk, continuing until the sauce thickens and coats the back of a wooden spoon.
Four: Remove the sauce from the heat and stir in grated cheddar, Dijon mustard, smoked paprika, salt and pepper.

Five: Combine the cooked pasta, sweetcorn and drained tuna with the cheese sauce. Add a splash of the reserved pasta water if the sauce needs loosening.
Six: Spoon the mixture into an ovenproof dish, sprinkle with grated Parmesan and bake at 180°C (160°C fan / gas 4 / 350°F) for 15–20 minutes until golden. For an extra-browned top, grill for 2–3 minutes.
Seven: Serve sprinkled with chopped parsley for a fresh finish.

Top Tips
- Whisk the sauce continuously while it thickens to avoid lumps; a whisk works best.
- Cook pasta to al dente since it will finish cooking in the oven — this prevents a mushy texture.
- Taste and adjust seasoning with salt and pepper before baking.
- Place the ovenproof dish on a baking sheet to catch any bubbling sauce and reduce oven mess.
🍴 Serving suggestions
Serve this creamy tuna pasta bake with crusty bread or focaccia and simple vegetables such as roasted Tenderstem broccoli, roasted courgettes or air-fried asparagus. A crisp green salad (for example, rocket with Parmesan) also pairs well.

📖 Variations
- Add olives for a briny contrast.
- Stir in frozen peas with the pasta during the last few minutes of cooking.
- Swap or combine cheeses — Gruyère or mozzarella work nicely.
- Fold in torn basil or chopped chives for extra freshness.
- Use a tomato-based sauce instead of the cheese sauce for a different flavour profile.
- Sprinkle garlic granules into the cheese sauce for more depth.
- For a crunchy topping, mix grated Parmesan with 2 tablespoons of dried breadcrumbs and scatter over the bake before cooking.
🥡 Storage

Store – Keep leftovers in an airtight container in the fridge for up to 3 days.
