5-Ingredient Oven Baked Canned Tuna

If you think canned tuna is only good for quick sandwiches, it’s time to upgrade your expectations. With just five simple ingredients and an oven, you can turn a humble pantry staple into a warm, satisfying dish that feels far more special than it has any right to be.

Why this recipe works

Canned tuna is affordable, protein-rich, and already cooked—so the real goal is adding moisture, flavor, and a bit of texture. Baking it brings everything together into a lightly golden, cohesive dish that’s somewhere between a casserole and a savory cake. It’s perfect for busy evenings when you want something homemade without the effort.
