Tuna Noodle Casserole with Crispy Panko
Tuna noodle casserole turns canned tuna, egg noodles, peas, mushrooms, and a creamy cheddar sauce into a crisp, cozy dinner that feeds 4 without stretching your budget.
This is the kind of casserole that tastes like home. The noodles stay tender, the tuna adds savory flavor, the peas pop with sweetness, and the buttered panko bakes into a golden, crunchy top.
Why You Will Love This Recipe
- Crispy top, creamy center: The panko turns light and crunchy while the noodles bake in a rich mushroom cheddar sauce.
- Pantry-friendly: Canned tuna, condensed soup, frozen peas, and noodles make this an easy weeknight meal.
- Comforting but practical: It is warm, filling, and made with simple real ingredients.
- Great for leftovers: The casserole reheats well for lunch the next day.
Fabian’s Budget Tip: Use store brand tuna, frozen peas, and block cheddar that you shred yourself. They usually cost less than name brand cans, fresh peas, and preshredded cheese. If mushrooms are pricey, use a little less and add a handful more noodles to stretch the casserole.
Ingredients (Serves 4)
- 12 ounces wide egg noodles (340 g)
- 2 cans tuna, drained, 5 ounces each (142 g each)
- 1 cup frozen peas (150 g)
- 8 ounces mushrooms, sliced (225 g)
- 1 can condensed cream of mushroom soup, 10.5 ounces (298 g)
- 3/4 cup milk (180 ml)
- 1 1/2 cups shredded cheddar cheese (170 g)
- 1 cup panko breadcrumbs (60 g)
- 3 tablespoons butter, divided (42 g)
Step-by-Step Instructions
1. Heat the Oven and Cook the Noodles
Heat the oven to 375°F (190°C). Bring a large pot of water to a boil. Add the egg noodles and cook until they are just tender but still have a little bite. They should feel soft on the outside but not mushy. Drain well so the casserole does not turn watery.
2. Soften the Mushrooms
Melt 1 tablespoon butter in a skillet over medium heat. Add the sliced mushrooms and cook until they shrink, darken, and smell savory. Let them sizzle until most of their moisture cooks off. This step gives the casserole a deeper flavor and keeps the sauce creamy.
3. Make the Creamy Filling
In a large mixing bowl, stir together the cream of mushroom soup and milk until smooth. Fold in the cheddar cheese, drained tuna, peas, cooked mushrooms, and drained noodles. Stir gently so the tuna stays in small tender flakes and the noodles get coated in sauce.
4. Add the Crispy Panko Topping
Spoon the noodle mixture into a baking dish. Melt the remaining 2 tablespoons butter and stir it with the panko breadcrumbs. Scatter the buttered panko evenly over the top. The crumbs should look lightly glossy so they bake up crisp instead of dry.
5. Bake Until Golden and Bubbling
Bake uncovered for 20 to 25 minutes, until the edges bubble and the panko turns golden. Your kitchen should smell like toasted butter, mushrooms, and melted cheddar. Let the casserole rest for 5 minutes before serving so the creamy sauce settles around the noodles.
Expert Troubleshooting and FAQs
Can I use frozen peas without thawing them first?
Yes. Frozen peas can go straight into the filling. They warm through in the oven and keep a bright, sweet bite.
Why did my tuna noodle casserole turn dry?
The noodles may have cooked too long, or the casserole may have baked too long. Cook the noodles just until tender and pull the casserole from the oven when the edges bubble and the panko is golden. If the mixture looks thick before baking, stir in an extra splash of milk.
Can I make this casserole ahead of time?
Yes. Mix the noodle filling and place it in the baking dish. Cover and chill for up to 24 hours. Add the buttered panko right before baking so it stays crisp.
Can I use a different pasta?
Yes. Short pasta shapes like rotini, shells, or penne work well. Cook them until just tender so they hold their shape in the creamy sauce.
How do I keep the panko topping crunchy?
Bake the casserole uncovered and add the buttered panko only right before it goes into the oven. If leftovers soften, warm them in the oven instead of the microwave for a crisper top.
