Ingredients
Main Ingredients

2 cans tuna (in water or oil), drained

1 can cream of mushroom soup
-
½ cup milk
-
1 cup frozen peas (or corn)

1 cup shredded cheddar cheese
-
1 small onion, finely chopped (optional)
-
Salt and black pepper to taste
Topping (Optional but Recommended)
-
½ cup breadcrumbs or crushed crackers
-
1–2 tbsp melted butter
Instructions
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the noodles according to package directions until just al dente. Drain and set aside.
Tip: Slightly undercook the pasta so it doesn’t become mushy while baking.
Step 2: Prepare the Sauce
In a large bowl, mix:
-
Cream of mushroom soup
-
Milk
-
Salt and black pepper
Stir until smooth. Taste and adjust seasoning if needed.
Step 3: Combine the Filling
Add to the bowl:
-
Cooked pasta
-
Drained tuna
-
Frozen peas
-
Shredded cheese
-
Chopped onion (if using)
Gently mix until everything is evenly coated with the sauce.
Step 4: Assemble the Casserole
Preheat your oven to 180°C (350°F).
Transfer the mixture to a greased baking dish and spread evenly.
Step 5: Add the Topping
Mix breadcrumbs or crushed crackers with melted butter. Sprinkle evenly over the top of the casserole.
This creates a crispy, golden topping that contrasts perfectly with the creamy interior.
Step 6: Bake
Bake uncovered for 25–30 minutes, or until:
-
The casserole is hot and bubbly
-
The topping is golden brown
Let rest for 5 minutes before serving.
Tips for the Best Tuna Casserole
