Spicy Tomato–Tuna Noodle Skillet Casserole With Aioli

This spicy tomato and tuna pasta bake is a sophisticated twist on a classic store-cupboard favourite. By toasting the pasta in the frying pan before simmering, you achieve a unique nutty flavour and a perfect al dente texture that stands up beautifully to the rich, savoury sauce. Infused with turmeric, roasted peppers and a hint of chilli, this high-protein dish offers a warming heat that is perfectly balanced by a cool, creamy homemade garlic aioli.

Designed as a single-pan meal, this recipe is ideal for busy weeknights when you want a nutritious, comforting dinner with minimal washing up. The combination of oil-packed tuna and anchovies provides a deep umami base, making it a satisfying choice for those seeking a heart-healthy, protein-rich Mediterranean-style supper. Serve it straight from the pan with a generous scattering of fresh parsley for a vibrant finishing touch.

Add pasta and cook, stirring often, until evenly coated in oil and lightly browned, about 5 minutes (depending on the size and shape of your pasta, you may need to work in batches). Using a slotted spoon, transfer to a large bowl. Reserve pan.

Drain tuna, reserving 2 tablespoons tuna oil. place oil in reserved pan and increase heat to medium. Add anchovy, 1/2 teaspoons salt, and reserved chopped vegetable mixture and season with pepper. Cook, stirring occasionally, until vegetables soften, 5–7 minutes. Add tomato paste and cook, stirring, until slightly darkened in colour, about 3 minutes. Mix in toasted pasta, tomatoes, turmeric, red pepper flakes, remaining 1/2 teaspoons salt, and 600ml water and bring to a boil. Cook, stirring occasionally, until pasta is slightly softened, 8–10 minutes. Remove from heat and stir in drained tuna and 60ml water.

Transfer skillet to oven and bake casserole until pasta is tender and juices at the edges are bubbling, about 15 minutes. Remove from oven.

Heat grill. Drizzle casserole with a little olive oil and grill until browned and crisped in spots, about 4 minutes.

Spoon some aioli over casserole and top with parsley if desired. Serve remaining aioli alongside.
