Recommended Products for This Recipe
After making this recipe countless times, I’ve found a few products that really make a difference in the final result.
1. Wild Planet Wild Albacore Tuna
This is hands down the best canned tuna for casseroles. It’s sustainably caught, packed in water, and has a firm, meaty texture that doesn’t fall apart when you mix it in.
The flavor is clean and not fishy at all, which makes a huge difference in the final dish.
2. Le Creuset Stoneware Rectangular Baking Dish
I use this baking dish for all my casseroles because it distributes heat so evenly.
The tuna casserole comes out perfectly golden on top without any burnt edges, and the stoneware keeps everything warm at the table. Plus, it’s gorgeous enough to go straight from oven to table.
3. Kikkoman Panko Breadcrumbs
Regular breadcrumbs just don’t compare to panko for that crispy, golden topping.
These Japanese-style breadcrumbs stay crunchy even after baking and create those beautiful ridges that catch all the butter. They’re the secret to that restaurant-quality crust.
4. Tillamook Sharp Cheddar Cheese
Sharp cheddar adds so much more flavor than mild cheese. Tillamook melts beautifully and has this rich, tangy taste that cuts through the creaminess of the soup.
I always buy the block and shred it myself for the best texture.
Step-by-Step Instructions: How to Make Tuna Casserole
Follow these detailed steps for perfect results every time.
1. Preheat Your Oven
- Set your oven to 375°F (190°C)

2. Cook the Egg Noodles
- Fill your large pot three-quarters full with water

- Drain in a colander and do not rinse
- Set aside while you prepare the sauce
3. Prepare the Creamy Base
- In a large mixing bowl, add the cream of mushroom soup

4. Combine All Ingredients
- Add the drained egg noodles to the creamy base
- Open and drain both cans of tuna thoroughly
- Flake the tuna with a fork and add to the bowl
- Add the frozen peas (no need to thaw)
- Add half of the shredded cheddar cheese (reserve ½ cup for topping)
- Gently fold everything together until evenly coated
- Be careful not to break up the noodles too much
5. Assemble the Casserole
- Lightly grease your 2-quart casserole dish with butter or cooking spray
- Transfer the tuna mixture to the prepared dish
- Spread it out evenly with a spoon
- Sprinkle the remaining ½ cup of cheddar cheese over the top

6. Add the Breadcrumb Topping

7. Bake to Golden Perfection
- Place the casserole dish on the center oven rack

- If the top browns too quickly, loosely cover with foil for the last 5 minutes
8. Rest and Serve

- Use a large spoon to scoop portions
- Serve hot and enjoy
This pairs wonderfully with my broccoli cheddar soup for a cozy meal.
Tips for The Best Tuna Casserole
Follow these tips to take your tuna casserole from good to absolutely amazing.
- Choose tuna packed in water and drain it thoroughly. Oil-packed tuna can make the casserole greasy.
- Cook noodles just until al dente since they’ll continue cooking in the oven.
- Use freshly shredded cheese instead of pre-shredded for better melting.
- Don’t skip the resting time after baking. It helps the casserole set.
- For extra flavor, add a splash of lemon juice to brighten the dish.
- Mix the breadcrumbs with melted butter thoroughly for even browning.
- If you prefer a crunchier topping, broil for the last 2 minutes of cooking time.
- Add a pinch of cayenne pepper to the cream base for a subtle kick.
- Let the casserole cool slightly before serving to avoid burning mouths.
Serving Suggestions
This tuna casserole is hearty enough to stand alone, but these sides make it even better.
A crisp green salad with vinaigrette cuts through the richness perfectly. The acidity balances all that cream and cheese beautifully.
Steamed green beans or roasted broccoli add color and nutrients to your plate. Simple vegetables are all you need alongside this filling main dish.
Here are more ideas to round out your meal:
- Fresh garden salad with ranch dressing
- Garlic bread or buttered dinner rolls
- Roasted asparagus with lemon
- Onion rings
- Sliced tomatoes with fresh basil
- Steamed broccoli with butter
- Coleslaw for a tangy contrast
For a heartier spread, serve it with my slow cooker beef stew.
Variations of Tuna Casserole
This recipe is incredibly versatile and adapts well to different dietary needs and preferences.
Try swapping the tuna for canned salmon or chicken for a different protein option. You can even use leftover rotisserie chicken for a shortcut.

Here are more variations to try:
- Gluten-Free: Use gluten-free egg noodles and gluten-free breadcrumbs

FAQs About Tuna Casserole
1. Can I use fresh tuna instead of canned?
Yes, you can use fresh tuna, but it requires extra preparation. Cook the fresh tuna first by searing or baking until just done, then flake it into chunks.
Canned tuna is more convenient and budget-friendly for this recipe, plus it has the right texture that holds up well during baking.
2. How do I make this casserole healthier?
Use low-fat cream of mushroom soup and reduce the amount of cheese by half. Add more vegetables like spinach, broccoli, or carrots to increase fiber and nutrients.
You can also use whole wheat egg noodles for added fiber and skip the butter in the breadcrumb topping by using olive oil spray instead.
3. Can I make tuna casserole without canned soup?
Absolutely! Make a simple white sauce by melting 2 tablespoons of butter, whisking in 2 tablespoons of flour, then gradually adding 1½ cups of milk.
Season with salt, pepper, and sautéed mushrooms for that classic flavor.
This homemade version gives you more control over sodium and ingredients.
4. What can I substitute for breadcrumbs on top?
Crushed potato chips, cornflakes, or crackers make excellent crunchy toppings. French-fried onions add a savory flavor that’s delicious too.
For a gluten-free option, use crushed rice cereal or gluten-free crackers.
5. Is tuna casserole safe to freeze?
Yes, this casserole freezes beautifully! Assemble it completely but don’t bake it. Wrap tightly in plastic wrap and aluminum foil, then freeze for up to 3 months.
Thaw overnight in the refrigerator before baking as directed, adding an extra 5-10 minutes to the baking time if needed.
