Jamie Oliver Tuna Pasta Bake is a baked pasta dish made by combining cooked pasta with tuna, a creamy tomato-based sauce, and cheese, then baking until bubbling and golden on top.
Bring a large pot of salted water to a boil. Cook the pasta until just al dente, about 1–2 minutes less than the packet instructions. Drain and set aside.
Heat olive oil in a large pan over medium heat. Add the chopped onion and cook for 4–5 minutes until softened. Stir in the garlic and cook for another minute.
Pour in the chopped tomatoes and milk. Add oregano, salt, and black pepper. Simmer gently for 8–10 minutes until slightly thickened.
Flake in the drained tuna and stir gently. Add peas if using. Simmer for another 2–3 minutes.
Preheat the oven to 180°C. Mix the cooked pasta into the sauce until evenly coated.
Transfer the mixture into a baking dish. Sprinkle grated cheddar and mozzarella on top. Bake for 20–25 minutes until golden and bubbling.
Allow to rest for 5 minutes before serving. Garnish with chopped parsley.
