This simple baked dinner is the kind of weeknight recipe that saves the day when the pantry looks bare but everyone still wants something hot and filling. Using undrained canned tuna right in the baking dish helps keep the fish moist while it cooks over sweet potato fries, and the result is a cozy, budget-friendly meal with very little prep and cleanup. It is a practical family-style supper that feels a little creative without making extra work.
Serve this with a crisp green salad, steamed green beans, or buttered peas to add a fresh side to the plate. If you want to stretch the meal for hungrier eaters, warm dinner rolls or simple coleslaw pair nicely, and a little ketchup, tartar sauce, or spicy mayo on the side gives everyone an easy way to dress up their portion.
4-Ingredient Oven Baked Tuna and Sweet Potato Fries
Servings: 4
Ingredients
2 cans undrained tuna, about 5 ounces each
1 bag frozen sweet potato fries, about 20 ounces
1 cup shredded cheddar cheese
2 tablespoons mayonnaise
Directions
1. Preheat your oven to 400°F and lightly grease a medium oven-safe ceramic casserole dish.
2. Spread the frozen sweet potato fries in an even layer in the casserole dish.
3. Spoon the undrained canned tuna evenly over the fries, breaking it up gently so it covers the top without mashing the fries underneath.
4. Dot the mayonnaise over the tuna, then use the back of a spoon to spread it lightly across the top.
5. Sprinkle the shredded cheddar cheese evenly over everything.
6. Bake for 25 to 30 minutes, or until the fries are tender, the cheese is melted and lightly golden, and the tuna is heated through. Let it rest for 5 minutes before serving.
Variations & Tips
For picky eaters: If your family prefers a milder flavor, use a mild cheddar and spread the tuna as evenly as possible so every bite gets a little of everything instead of big pockets of fish.
Extra crispy fries: If you like firmer sweet potato fries, bake the fries by themselves for 10 minutes first, then add the tuna, mayonnaise, and cheese for the remaining bake time.
Pan size tip: Try not to overcrowd the casserole dish. A dish around 8-by-11 inches or a similar medium size works well so the fries can roast instead of steam too much under the tuna.
Add a pantry seasoning: Even though this version keeps to four main ingredients, a light sprinkle of black pepper, garlic powder, or paprika on top before baking can add a little extra flavor if you have it on hand.
Make it feel more complete: A spoonful of tartar sauce, a squeeze of lemon, or a handful of chopped parsley added at the table can brighten the finished dish and make it feel a little more special.
