1. Classic Tuna Casserole Recipe
Ingredients
To prepare this delicious tuna casserole for 8 servings, gather the following ingredients:
- 1 package (12 oz.) whole wheat wide noodles or egg noodles
- 2 cans (10 ¾ oz. each) cream of chicken soup
(Look for low-sodium or “Healthy Request” versions for a lighter option.) - 2 cans (5 oz. each) solid white albacore tuna in water, drained
(You can use any type of canned tuna you prefer.) - 1 can (5 oz.) sliced water chestnuts, drained and roughly chopped (Optional, adds crunch)
- 2 cups frozen peas (No need to thaw; they’ll cook in the oven.)
- 1 ½ cups grated sharp cheddar cheese, divided (1 cup for the mix, ½ cup for topping)
Instructions
Preheat the Oven
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or a light coating of oil.
Cook the Noodles
Bring a large pot of salted water to a boil. Add the noodles and cook according to package directions until al dente. Drain and set aside.
Make the Casserole Mixture
In a large mixing bowl, stir together the cream of chicken soup, drained tuna, chopped water chestnuts (if using), frozen peas, and 1 cup of the shredded cheddar cheese.
Combine with Noodles
Add the drained noodles to the tuna mixture and gently fold everything together until well coated.
Transfer to Baking Dish
Pour the mixture into the prepared baking dish and spread it out into an even layer.
Top with Cheese
Sprinkle the remaining ½ cup of cheddar cheese evenly over the top of the casserole.
Bake
Bake uncovered for 25–30 minutes, or until the casserole is bubbly and the cheese on top is golden brown.
Cool & Serve
Let the casserole sit for 5–10 minutes before serving. This helps it firm up and makes it easier to scoop.
2. Tips for Perfect Tuna Casserole
Use High-Quality Tuna
Solid white albacore tuna offers a firmer texture and cleaner taste, enhancing the casserole’s flavor.
Undercook Noodles Slightly
Cook noodles just until al dente, as they will continue to soften while baking in the sauce.
Add Crunch on Top
For added texture, sprinkle breadcrumbs or crushed crackers over the cheese before baking.
Season to Taste
Taste the mixture before baking and adjust with salt, pepper, or a pinch of garlic powder for extra depth.
Let It Rest After Baking
Allowing the casserole to rest once out of the oven helps the sauce thicken and flavors meld together.
3. Variations & Substitutions
Swap the Soup Base
Replace cream of chicken soup with cream of mushroom or cream of celery for a different flavor profile.
Add Fresh Vegetables
Stir in sautéed mushrooms, onions, or bell peppers for added nutrition and variety.
Try Different Cheeses
Use a blend of cheeses like mozzarella, Monterey Jack, or even a smoky gouda for a twist.
Make It Gluten-Free
Substitute gluten-free noodles and a gluten-free condensed soup to meet dietary needs.
Boost the Protein
Add a handful of cooked chicken or a can of white beans to make the casserole even heartier.
4. How to Store & Reheat Leftovers
Storing:
Once the casserole has cooled, transfer leftovers to an airtight container and store in the refrigerator for up to 3–4 days. You can also freeze individual portions for up to 2 months. Wrap them tightly in foil or use freezer-safe containers to prevent freezer burn.
Reheating:
To reheat refrigerated leftovers, place a portion in a microwave-safe dish and heat on medium power for 2–3 minutes, stirring halfway through. If reheating a large portion or the entire casserole, cover with foil and warm in a 350°F (175°C) oven for 20–25 minutes or until heated through. Add a splash of milk or broth if the casserole seems dry.
Tuna casserole remains a timeless favorite for its ease, affordability, and nostalgic comfort. With a few thoughtful additions and substitutions, you can make this classic dish your own while still enjoying the creamy, cheesy satisfaction it’s known for. Whether you’re feeding a crowd or planning for leftovers, this tuna casserole is sure to deliver on flavor and convenience every time.
