5-Ingredient Oven Baked Canned Tuna

How to make it

Start by preheating your oven to 375°F (190°C). Lightly grease a small baking dish so nothing sticks later.

In a mixing bowl, combine the drained tuna with two eggs. The eggs act as a binder, holding everything together as it bakes. Add a few tablespoons of mayonnaise to keep the mixture moist and creamy, then stir in a generous handful of shredded cheese for richness and flavor.

Once everything is well mixed, fold in breadcrumbs. These help give the dish structure and a slightly firm texture, preventing it from turning too soft.

Transfer the mixture into your prepared baking dish and spread it evenly. If you like a crisp top, sprinkle a little extra cheese or breadcrumbs over the surface.

Bake for about 20–25 minutes, or until the top is golden and the center is set. Let it cool for a few minutes before slicing—this helps it hold its shape.

What it tastes like

The result is savory, creamy, and lightly crisp on top. The tuna becomes milder in flavor as it bakes, blending with the richness of the cheese and mayo. It’s comforting without being heavy.

Easy ways to customize

Once you’ve tried the basic version, you can easily adapt it:

• Add chopped onions or garlic for extra flavor
• Mix in herbs like parsley or dill
• Toss in vegetables such as peas or corn
• Spice it up with a dash of chili flakes or mustard

Serving ideas

Serve it warm with a simple salad, roasted vegetables, or even tucked into a sandwich. It also works well as leftovers, making it a practical meal prep option.
