Tip!

You’ll find all ingredient quantities in the recipe card below.

Wild Albacore Tuna: Using tuna packed in water and with no added salt keeps it light and lets the other flavors shine.
Eggs: They bind everything together and give structure to the waffles.
Shredded Mozzarella Cheese: Adds a mild, melty creaminess making the waffles nice and tender inside.
Mayonnaise: Provides moisture and helps with richness without overpowering.
Lemon Juice: Just a touch for brightness to balance the tuna’s savory notes.
Green Onions: Bring a subtle, fresh sharpness that livens up the batter.
Salt: Enhances all the flavors without being overwhelming.
Cherry Tomatoes: Halved for juiciness and a pop of color in the topping.
Avocado: Adds creaminess and healthy fats that pair flawlessly with the tuna.
Balsamic Vinegar (optional): Gives a slight tangy sweetness to elevate the tomato and avocado topping.

Directions

Step 1: Preheat your oven to 250 degrees Fahrenheit to keep the waffles warm and crisp once they’re cooked.

Step 2: Open your cans of tuna and place the fish into a large mixing bowl. Use a fork to break up any large chunks so it’s evenly flaked.

Step 3: Crack the eggs into the bowl with the tuna and whisk them together thoroughly. Then add the shredded mozzarella, mayonnaise, lemon juice, chopped green onions, and salt. Stir everything well until fully combined—it should form a slightly thick batter.

Step 4: Heat a mini waffle iron according to the manufacturer’s instructions. Once hot, spoon about ¼ cup of the batter into the waffle iron. Close it and cook for roughly 3 to 4 minutes, or until the waffles are cooked through and golden. Repeat this for the rest of the batter.

Step 5: Arrange all the cooked waffles in a single layer on a baking sheet and place it in your preheated oven for 5 minutes. This step ensures they warm evenly and regain a lovely crisp texture.

Step 6: While the waffles finish in the oven, prepare the topping by gently tossing together the halved cherry tomatoes, chopped avocado, and optional balsamic vinegar in a bowl.

Step 7: Serve your warm tuna waffles immediately with a generous spoonful of the cherry tomato and avocado topping on each. Enjoy the burst of flavors and textures in every mouthful!

How to Serve This Tuna Waffles with Cherry Tomato and Avocado Topping Recipe

When I serve this dish, I like to keep the presentation fresh and simple. I usually plate two or three waffles per person and spoon the vibrant cherry tomato and avocado topping on each one generously. To make it look extra special, I sometimes add a few fresh basil leaves or microgreens on top for color and a hint of herbal brightness.

For sides, I often reach for a crisp green salad or some roasted asparagus to keep the meal balanced without overshadowing the delicate tuna waffles. If I’m serving this at brunch, a light citrus salad or even some pickled vegetables work wonderfully to add acidity and contrast. I find that serving the waffles warm really brings out their crispness, but the topping tastes amazing chilled or at room temperature.

To drink alongside, I love pairing this dish with a chilled Sauvignon Blanc or a light, citrusy sparkling water with a splash of lime. For a non-alcoholic option, fresh iced green tea or a cucumber mint cooler complements the fresh, summery flavors beautifully. This recipe shines for casual weeknight dinners, leisurely weekend brunches, or even as an interesting appetizer for a holiday gathering.

Variations

I’m always excited to experiment with this dish, and one of my favorite tweaks is swapping mozzarella for a sharper cheese like aged cheddar or even feta to add a tangy depth. For extra herbs, stirring in some fresh dill or parsley into the batter adds a wonderful burst of flavor that works beautifully with the tuna.

For those looking to make this recipe gluten-free, the great news is it naturally contains no wheat flour—but if you want a lighter waffle texture, adding a bit of gluten-free flour or chickpea flour can work well. And while this recipe isn’t suitable for vegans, you could try a creative alternative by using a chickpea “tuna” salad and vegan cheese substitute if you want a similar experience.

If I want to change the cooking method up, sometimes I make these waffles in a small nonstick skillet or griddle as savory mini pancakes, although the texture is a bit less crisp. Another variation is to turn the topping into a chunky salsa or relish by adding finely diced red onion, cilantro, and a squeeze of lime—adding a different but delightful flavor dimension.

Storage and Reheating

Storing Leftovers

When I have leftovers, I store the tuna waffles in an airtight container in the fridge for up to 2 days. It’s best to separate the toppings from the waffles so the waffles stay crispier and don’t get soggy from the avocado and tomatoes.

Freezing

I wouldn’t recommend freezing the waffles with the fresh topping, but you can freeze the plain tuna waffles on a baking sheet lined with parchment paper for about 1 to 2 months. Once frozen solid, transfer them to a freezer-safe bag or container. This way, you can simply reheat them later and add freshly prepared topping for the best taste and texture.

Reheating

The best method to reheat leftovers or frozen waffles is in a toaster oven or a conventional oven at 350 degrees Fahrenheit for about 5 to 7 minutes. This helps to restore their crispiness without drying them out. Avoid microwaving if possible, as that tends to make the waffles soggy and rubbery. Reheat the topping separately or freshly prepare it, as avocado and tomatoes lose their fresh texture when warmed.

FAQs

Can I use fresh tuna instead of canned for this recipe?

While fresh tuna can be used, it requires cooking and flaking first, which changes the texture and prep time. The recipe is designed for canned tuna for convenience and consistent flavor. If using fresh, I recommend lightly poaching or searing it before chopping finely.

Is this recipe suitable for meal prep?

Yes, this recipe is great for meal prep since the waffles can be made ahead and reheated easily. Just keep the topping separate until serving to ensure freshness and texture stay intact.

Can I make this recipe dairy-free?

Absolutely! You can substitute the mozzarella with a dairy-free cheese alternative or simply omit it, though the waffles may be less melty and rich. Adding a little extra mayo or mashed avocado in the batter can help keep them moist.

What’s the best way to keep the waffles crispy?

Keeping waffles crisp depends on avoiding moisture. I recommend placing cooked waffles on a wire rack to cool and storing them uncovered briefly if needed before refrigerating. Reheating in the oven or toaster oven also helps restore crispness.

Could I add some spices or herbs to the batter?

Yes, adding paprika, cayenne pepper, or dried herbs like oregano or thyme gives the waffles an extra flavor boost. Fresh herbs such as dill or basil mixed in before cooking can also brighten the flavor beautifully.
