Comforting, hearty, and simply delicious, this tuna and potato bake recipe is an easy-to-make and budget-friendly dish, perfect for busy weeknights. Packaged scalloped potatoes, canned tuna, and a succulent and creamy mayonnaise-based sauce create an irresistible dish that's hearty and filling. Some tangy cheddar cheese and a touch of mustard bring the flavors together in this layered casserole. A crispy bottom of potatoes and a layer of creamed tuna topped with a cheesy crust are all you need to feed a family in less than one hour. Serve your tuna potato bake with steamed broccoli, roasted asparagus, or a fresh green salad.
By using store-bought scalloped potatoes you are saving tons of time. The often overlooked canned tuna delivers a lot of protein and nutrition at a low cost—a 6-ounce serving of water-canned tuna has a whopping 40 grams of protein and just 5 grams of fat. Choose canned tuna that is packed in water if you want a lighter dish, or go for the oil-packed version for a heartier dish. In either case, choose a sustainably sourced tuna low in mercury. Using skipjack tuna is your best bet.
For the Potatoes
5 ounces scalloped potatoes, plus milk, butter, and water as directed on the package
1 medium onion, thinly sliced
For the Tuna
3 tablespoons butter
3 tablespoons all-purpose flour
1/2 teaspoon salt
1/8 teaspoon freshly ground black pepper
1 1/4 cups milk
2 (7-ounce) cans tuna, drained and flaked
1/2 cup mayonnaise
1/2 cup grated cheddar cheese
1/2 teaspoon hot pepper sauce
1 teaspoon prepared mustard
1 dash paprika, optional
Cook the Potatoes and Onions
Gather the ingredients.
Prepare scalloped potatoes for baking, following package directions, adding sliced onion. Arrange the potato and onion mixture in a 2-quart casserole dish. Preheat the oven to the temperature indicated on the package of scalloped potatoes.
Bake for 20 to 25 minutes, or until the potatoes are tender. Remove from oven and set aside.
Make the Creamy Tuna
In a saucepan over low heat, melt the butter. Stir in the flour, salt, and pepper.
Gradually stir in the milk. Cook, stirring constantly, until the sauce has thickened and is smooth.
Fold in the drained tuna.
Assemble the Casserole
Pour the tuna sauce mixture over the potatoes.
In a bowl, combine the mayonnaise, cheese, hot sauce, and mustard.
Spread the cheese mixture over the tuna layer.
Return the casserole to the oven. Bake, uncovered, for 10 to 15 minutes, until hot and bubbly. If desired, sprinkle with paprika before serving.
