Ingredients
Method
- Boil noodles in salted water until just tender, about 8 minutes, then drain.
- Preheat oven to 375°F (190°C). Melt 3 tbsp butter in a skillet, whisk in flour and cook 1 minute. Slowly whisk in milk and simmer until thickened, 3 to 5 minutes. Remove from heat and stir in cheddar, parmesan, salt, and pepper until smooth.
- Fold noodles, tuna, and peas into the sauce until evenly coated, about a minute.
- Transfer to a 2-quart baking dish. Toss panko with 2 tbsp melted butter and sprinkle on top.
- Bake until bubbly and golden, 25 to 30 minutes. Rest 5 minutes, then scoop into bowls and serve.
Notes
You can assemble the unbaked casserole (without topping) a day ahead and refrigerate it. When you’re ready to bake, add the breadcrumbs and extend the bake time by 5 minutes. If you don’t have panko, crushed saltines or regular breadcrumbs work well.
