How to Make 5-Ingredient Oven Baked Canned Tuna
Ingredients:
- 2 (5-ounce) cans tuna in water or oil, undrained
- 2 tablespoons mayonnaise
- 1 tablespoon yellow mustard
- 1 teaspoon garlic powder
- 1 teaspoon dried Italian seasoning (or dried parsley or oregano)
Directions:
- Preheat your oven to 375 degrees F (190 degrees C). Place a small oven rack in the center of the oven so the tuna bakes evenly.
- Set a clear, oven-safe glass baking dish (about 8×8 inches or similar) on the counter. Open both cans of tuna, but do not drain them.
- Carefully slide or tap the tuna out of each can directly into the glass baking dish, keeping the tuna in its whole cylindrical shape as much as possible. The extra liquid should pour into the dish too.
- Use a spoon to gently nudge the tuna cylinders so they sit side by side in the middle of the dish, with a little space around them for the juices to bubble.
- In a small bowl, stir together the mayonnaise, yellow mustard, garlic powder, and dried Italian seasoning until smooth and creamy.
- Spoon the seasoned mayo mixture evenly over the tops and sides of the tuna cylinders, spreading gently so you do not break them apart. It is fine if some of the mixture drips into the juices in the bottom of the dish; that just adds flavor.
- Place the glass baking dish in the preheated oven and bake for 18 to 22 minutes, or until the tuna is heated through, the edges are lightly golden, and the sauce is bubbling around the sides.
- Carefully remove the dish from the oven and let the tuna rest for 3 to 5 minutes. This helps the hot juices settle so they are easier (and safer) to spoon over the tuna when serving.
- Serve the whole tuna cylinders as-is for a rustic, hearty look, spooning some of the seasoned juices over the top. If your family prefers, you can gently break them apart at the table and mix with the juices for a more shredded, saucy tuna.
How to Serve 5-Ingredient Oven Baked Canned Tuna

How to Store 5-Ingredient Oven Baked Canned Tuna
If you have leftovers, let the dish cool to room temperature. Then, cover it with plastic wrap or transfer it to an airtight container and store it in the refrigerator. It will keep for about 2 to 3 days. When ready to eat, you can reheat it in the oven or microwave until warmed through.
Tips to Make 5-Ingredient Oven Baked Canned Tuna
- For a richer flavor, you can use tuna packed in oil instead of water.
- Feel free to customize the seasoning to your taste. Adding some red pepper flakes can give it a nice kick!
- You can also top it with shredded cheese in the last few minutes of baking for a cheesy twist.
Variation
If you want to mix things up, consider adding diced vegetables like bell peppers or onions to the sauce before spreading it on top of the tuna. This adds some crunch and extra nutrition!
