This 5-ingredient oven baked black pepper tuna and waffle fries dinner is the kind of simple sheet pan meal that helps busy nights feel a little easier. By baking undrained black pepper tuna right over frozen waffle fries, you get a savory, peppery topping that flavors the fries as everything cooks together. It is a practical pantry-meets-freezer recipe with very little prep, and it makes a hearty, casual meal that is especially nice when you want something filling without standing over the stove.

Serve this with a crisp green salad, steamed green beans, coleslaw, or simple sliced tomatoes to balance the richness of the fries and tuna. A side of tartar sauce, ranch, lemon wedges, or extra hot sauce can make it feel a little more fun at the table, and fresh fruit is an easy finish if you are feeding family or friends.

5-Ingredient Oven Baked Black Pepper Tuna and Waffle Fries

Ingredients

1 bag (26 to 32 ounces) frozen raw waffle fries

2 cans (5 ounces each) black pepper tuna, undrained
1 cup shredded cheddar cheese
2 green onions, thinly sliced
1 tablespoon lemon juice

Directions

1. Preheat the oven to 425°F. Lightly coat a large oven-safe sheet pan with cooking spray or line it with parchment for easier cleanup.

2. Spread the frozen waffle fries in an even layer on the sheet pan. Spoon the undrained black pepper tuna evenly over the fries, including the liquid from the cans, then drizzle the lemon juice across the top.

3. Bake for 20 to 25 minutes, or until the fries are hot and turning golden around the edges and the tuna is heated through.

4. Sprinkle the shredded cheddar cheese over the top and return the pan to the oven for 3 to 5 minutes, just until the cheese is melted.

5. Remove from the oven, scatter the sliced green onions over the top, and serve right away while hot.

Variations & Tips

For picky eaters: Leave one part of the pan with just waffle fries and cheese, then add the tuna only to the rest. That way everyone can build their own plate without extra work.

Extra crispy tip: If you want the fries a little crisper, bake the waffle fries by themselves for 8 to 10 minutes first, then add the tuna and continue baking. This helps keep the centers fluffy while the edges stay nicely crisp.

Cheese swap: Monterey Jack, mozzarella, or a cheddar blend all work well here. Use what you already have in the refrigerator for an easy weeknight shortcut.

Fresh finish: A little chopped parsley, dill, or an extra squeeze of lemon right before serving brightens the whole pan and helps balance the savory peppery flavor of the tuna.

Serving tip: This dish is best served right out of the oven while the fries still have texture. If you expect leftovers, keep a portion of the tuna separate and add it after baking so the reheated fries do not soften as much.
