🧾 Ingredients
To make these tuna salad stuffed tomatoes, you only need a handful of basic ingredients. Here's a breakdown of what you'll need:
- Tomatoes: Choose large, firm tomatoes like beefsteak or heirloom varieties.
- Canned Tuna: Tuna packed in water is lighter and healthier, while oil-packed tuna offers a richer taste. Choose a good quality brand for best flavor.
- Mayonnaise: Regular or light mayo both work; for extra flavor, try a garlic or lemon mayo.
- Capers: Small, brined capers are best. They are optional, but they add a salty, tangy flavor.
- Corn: Use canned sweet corn for the easiest option.

🍽 Serving Suggestions
Tuna Salad Stuffed Tomatoes are best served cold or at room temperature. Arrange them on a platter with a drizzle of olive oil and a sprinkle of fresh herbs like parsley or dill. They make a great appetizer, side dish, or even a light entrée served alongside a green salad or crusty bread. For parties, try making mini versions with cherry tomatoes for a bite-sized treat.
❄️ Storage & Reheating
These stuffed tomatoes are best eaten fresh, but they do store well for short periods if needed.
In the Fridge:
Tip: If prepping in advance, consider storing the tuna salad separately and stuffing the tomatoes just before serving to avoid sogginess.
Storage Time: 1-2 days
How to Store: Place stuffed tomatoes in an airtight container lined with a paper towel to absorb excess moisture. Store in the fridge.
💭 Recipe FAQs
Yes! You can prepare the tuna salad up to 3 days in advance and store it in the fridge. For best results, stuff the tomatoes just before serving.
Scoop out the seeds and excess pulp from the tomatoes, then turn them upside-down on a paper towel to drain for 10-15 minutes before stuffing.
Chunk light tuna in olive oil is a popular choice because it's mild and flavorful. Albacore tuna has a firmer texture and richer flavor-great if you want a more upscale feel. Try also flavored versions like this Lemon and Pepper Tuna.
⭐ Top tip
Let the tuna salad sit for 10-15 minutes in the fridge before stuffing the tomatoes.
This allows the flavors to meld together and creates a more cohesive, delicious filling. If you're short on time, even a few minutes can make a difference.

Looks like summer on a plate! We eat these often in the hotter months. So easy to make and so tasty. I'm intrigued by your addition of corn.
Jessica Montanelli says
Thanks! I also grew up eating these in summer. I know corn is unusual in tuna salad, but it's how my family always made them and I like the extra sweetness. 😀
