How to Make Baked Tuna in the Oven
1. Preheat the Oven
Preheat your oven to 375°F (190°C). Position an oven rack in the center of the oven for even baking.
2. Add the Tuna
Use a small oven-safe glass baking dish, approximately 8 x 8 inches.
Open the tuna cans but do not drain them. Carefully transfer the tuna and its liquid into the baking dish. Keep the tuna in larger pieces as much as possible.
Arrange the tuna pieces side by side in the center of the dish.
3. Make the Creamy Seasoning
In a small bowl, combine the mayonnaise, yellow mustard, garlic powder, and Italian seasoning.
Stir until the mixture is smooth and well combined.
4. Add the Sauce
Spoon the seasoned mayonnaise mixture over the tuna. Gently spread it across the top without breaking the tuna apart too much.
Some of the sauce will naturally mix with the tuna juices while baking, creating a flavorful sauce around the fish.
5. Bake
Place the baking dish in the preheated oven.
Bake for 18–22 minutes, or until the tuna is thoroughly heated and the sauce is bubbling around the edges with a lightly golden surface.
6. Rest and Serve
Carefully remove the dish from the oven and allow it to rest for 3–5 minutes.
Spoon some of the flavorful juices over the tuna before serving.
For a more traditional tuna texture, gently break the tuna apart and mix it with the creamy sauce.

Easy Baked Tuna Recipe Variations
Cheesy Tuna Bake
Sprinkle 2–3 tablespoons of shredded cheddar or grated Parmesan over the tuna during the final 5 minutes of baking. Continue baking until the cheese is melted and lightly golden.
Crispy Breadcrumb Topping
Add a few tablespoons of plain breadcrumbs over the top before baking. Combine them with Parmesan for an extra-crispy topping.
Spicy Baked Tuna
Add crushed red pepper flakes, cayenne pepper, or freshly ground black pepper for a little heat.
Tuna and Vegetables
Add thinly sliced onions, bell peppers, peas, or other quick-cooking vegetables around the tuna before baking.
Mild Tuna Bake for Kids
For a milder flavor, reduce or omit the mustard and use mayonnaise as the creamy base. A tiny pinch of sugar can soften the sharpness even further.
Helpful Tips for the Best Baked Tuna
Use intact cans: Always check that tuna cans are not bulging, leaking, heavily rusted, or severely dented.
Don’t overbake: Canned tuna is already cooked, so this recipe is primarily about reheating it and developing the flavors. Overbaking can make tuna dry.
Keep some of the liquid: The tuna liquid helps keep the dish moist and contributes to the savory juices.
Add cheese near the end: Adding cheese during the final few minutes helps prevent excessive browning.
Rest before serving: Allowing the dish to sit for several minutes makes the hot juices easier to handle and serve.
Use oven protection: Glass baking dishes become extremely hot. Always use oven mitts and place the hot dish on a heat-resistant trivet.
