Instructions
Prepare and cook
- Heat the oven to 375°F (190°C). Cook egg noodles in unsalted boiling water until slightly firmer than al dente, about 2 minutes less than the package timing; drain.
- Heat 28 g butter and 15 ml olive oil in a large skillet. Cook mushrooms and onion over medium-high heat until softened and the released liquid mostly evaporates, 5–7 minutes.
- Add remaining butter, then flour, and stir for 1 minute. Gradually whisk in milk and stock. Simmer gently about 5 minutes until thickened. Stir in lemon juice, mustard, salt and pepper.
- Remove from heat. Fold in noodles, peas, drained tuna and 115 g cheddar, keeping some tuna flakes intact. Transfer to a 9-by-13-inch baking dish and scatter remaining cheddar over the top.
- Toss panko with remaining 10 ml olive oil and paprika; sprinkle over the casserole. Bake 25–30 minutes until bubbling, golden and 165°F (74°C) in the center. Rest 5 minutes, then divide into eight portions.
