Crispy Zucchini and Tuna Burgers for a Light Summer Meal
Zucchini has a funny way of taking over summer kitchens. One minute you buy a couple because they look fresh and cute, and the next minute you’re wondering how many more zucchini dinners you can make before everyone notices.
These zucchini and tuna burgers are one of the best answers. They’re light but satisfying, crispy on the outside, soft and juicy in the middle, and simple enough for a weeknight lunch or dinner. The tuna adds savory flavor, the cheese helps bind everything together, and the fresh parsley keeps the whole thing bright.
Serve them hot with boiled new potatoes and a quick parsley sauce, and you’ve got the kind of easy summer meal that feels cozy without feeling heavy.
Why these zucchini and tuna burgers work so well
A good vegetable burger needs balance. Too much moisture and it falls apart. Too many breadcrumbs and it turns dry. This recipe lands right in the middle.
The cooked zucchini gives the burgers a tender, almost creamy center. Canned tuna brings protein and a salty, savory flavor that stands up well to the mild zucchini. Grated cheese melts into the mixture and helps everything hold together. Breadcrumbs and a little flour soak up extra moisture, while the egg ties it all into a mixture you can shape easily.
The final breadcrumb coating is what gives these burgers their best feature, that golden, crispy crust. You don’t need deep frying. A shallow layer of oil in a skillet is enough to brown both sides beautifully.
These are also great because they use simple pantry and fridge staples. No complicated prep, no special equipment, and no long cooking time.
Ingredients you’ll need
This recipe makes a small batch, enough for about 6 to 8 small burgers, depending on how large you shape them.
Ingredient | Amount |

Canned tuna, drained | 80 g, about 2.8 oz |
Grated cheese | 70 g, about 2.5 oz |
Egg | 1 large |
Breadcrumbs | 100 g, about 1 cup, plus more for coating |
All-purpose flour | 1 tablespoon |
Dry seasoning | To taste |
Black pepper | To taste |
Fresh parsley | A small handful, finely chopped |
Oil for frying | As needed |
A few ingredient notes help a lot here.
For the zucchini, choose firm ones with smooth skin. Smaller and medium zucchini usually have better texture and fewer seeds. The original method peels the zucchini, which gives the burgers a softer texture and milder flavor. If your zucchini are young and tender, you can leave some peel on for color, but peeled zucchini blends more smoothly into the mixture.
For the tuna, use canned tuna in water or oil, but drain it very well. If you use tuna packed in oil, the flavor will be richer. If you use tuna in water, the burgers will taste a little lighter.
For the cheese, use something that melts nicely and isn’t too wet. Mild cheddar, mozzarella, Monterey Jack, gouda, or a simple pre-grated cheese blend can all work. If your cheese is very salty, go easy on the dry seasoning.
Dry seasoning can mean an all-purpose vegetable seasoning, seasoned salt, or your favorite savory seasoning blend. Since many seasoning blends already contain salt, taste the mixture before adding extra.
How to make zucchini and tuna burgers
The process is easy, but there are a few small steps that make the burgers hold together and crisp up properly.
1. Cook the zucchini until tender
Peel the zucchini and cut it into cubes.
Steam the cubes until they’re soft enough to mash with a fork. Steaming is best because it adds less water than boiling. If you don’t have a steamer basket, you can cook the zucchini in a small amount of water, then drain it very well.
Once cooked, let the zucchini cool for a few minutes. This matters because hot zucchini can make the egg cook unevenly when you mix everything together.
When the zucchini is cool enough to handle, mash it with a fork or potato masher. You don’t need a perfectly smooth puree. A little texture is nice.
If the mashed zucchini looks watery, press it gently through a fine mesh strainer or squeeze it lightly in a clean kitchen towel. You don’t have to remove every drop, but the mixture shouldn’t look soupy.
2. Mix the burger base
Place the mashed zucchini in a large bowl.
Add the drained tuna, grated cheese, breadcrumbs, flour, egg, and finely chopped parsley. Season with dry seasoning and black pepper. Mix everything until it comes together into a soft but shapeable mixture.
The texture should feel moist, not runny. If it sticks to your hands too much or doesn’t hold its shape, add a little more breadcrumbs, one tablespoon at a time.
Letting the mixture sit for 5 to 10 minutes is a helpful little trick. The breadcrumbs will absorb moisture from the zucchini and egg, which makes the burgers easier to form.
3. Shape the burgers
Scoop out portions of the mixture and shape them into small patties.
Keep them fairly compact and not too thick. About 1/2 inch thick is a good size because the outside can brown nicely while the inside heats through.
Pour some extra breadcrumbs onto a plate. Coat each burger on both sides and around the edges. Press gently so the crumbs stick, but don’t squash the patties flat.
If the patties feel soft after shaping, place them in the fridge for 15 minutes before frying. This isn’t required, but it helps if your kitchen is warm or the zucchini was extra moist.
4. Fry until golden and crisp
Heat oil in a skillet over medium heat. You want enough oil to coat the bottom of the pan generously, but you don’t need to submerge the burgers.
Once the oil is hot, add the patties in a single layer. Don’t overcrowd the pan. If needed, cook them in batches.
Fry until the bottom is golden brown, then carefully flip and cook the other side. They should be crisp on the outside and heated through in the center.
Transfer the fried burgers to a plate lined with paper towels. This absorbs excess oil and keeps the crust from feeling greasy.
Tips for burgers that don’t fall apart
Zucchini is full of water, so the biggest challenge is moisture. These tips help you get burgers that are tender but still hold their shape.
Drain everything well.
The zucchini should be cooked and drained, and the tuna should be pressed dry enough that it flakes easily without dripping.
Let the mixture rest.
Breadcrumbs need a few minutes to absorb the liquid. If you shape the burgers right away, the mixture may seem looser than it really is.
Use medium heat.
If the heat is too high, the outside browns before the inside firms up. If it’s too low, the burgers soak up oil and turn soft. Medium heat gives you the best crust.
Flip gently.
Use a wide spatula and flip only once if you can. The patties are more delicate than meat burgers, especially during the first minute or two in the pan.
Make smaller patties.
Small burgers are easier to handle and less likely to crack. They also cook faster and get more crispy edges, which is always a win.
A quick parsley sauce to serve on the side
The original serving idea pairs these zucchini and tuna burgers with boiled new potatoes and a light parsley sauce. That combo is simple, fresh, and perfect for summer.
Here’s an easy sauce you can stir together while the burgers cook.
Simple fresh parsley sauce
You’ll need:
1/2 cup plain Greek yogurt or sour cream
1 to 2 tablespoons finely chopped fresh parsley
1 teaspoon lemon juice
1 small garlic clove, grated or finely minced
Salt and black pepper to taste
A splash of water, if you want it thinner
Mix everything in a small bowl. Taste and adjust. Add more lemon if you want it brighter, or more parsley if you want a stronger herb flavor.
If you prefer a dairy-free sauce, mix chopped parsley with olive oil, lemon juice, garlic, salt, and pepper. It’s more like a loose herb dressing, and it tastes great over both the burgers and potatoes.
What to serve with zucchini and tuna burgers
Boiled new potatoes are the classic choice here. They’re tender, mild, and filling without making the meal feel too heavy. Toss them with a little butter or olive oil, chopped parsley, and salt while they’re still warm.
A few other easy sides also work well:
A tomato and cucumber salad with vinegar and olive oil
A simple green salad with lemon dressing
Corn on the cob
Roasted or grilled summer vegetables
Rice or couscous with herbs
Pickled onions or pickles for a tangy bite
For lunch, two or three small burgers with salad may be enough. For dinner, add potatoes or bread and a sauce. You can also tuck the burgers into pita bread with lettuce, sliced tomato, and yogurt sauce for a relaxed sandwich-style meal.
Easy variations to try
This recipe is flexible, so you can adjust it based on what you already have.
Add lemon zest for brightness
A little lemon zest in the mixture makes the tuna taste fresher. Start with 1/2 teaspoon. You can add a squeeze of lemon juice after frying too.
Use dill instead of parsley
Dill pairs beautifully with both tuna and zucchini. If you love fresh, slightly grassy flavors, swap some or all of the parsley for dill.
Add green onions
Finely chopped green onions give the burgers a mild onion flavor without overpowering the zucchini. One or two green onions are enough for this batch.
Make them a little spicy
Add a pinch of chili flakes, cayenne, or smoked paprika. Smoked paprika is especially good if you want a deeper, warmer flavor.
Change the cheese
A sharper cheese gives more flavor. A milder cheese keeps the burgers soft and mellow. Parmesan can work too, but use a smaller amount because it’s salty and dry.
Can you bake them instead of frying?
Yes, but the texture will be different.
Frying gives these burgers their best crispy outside. Baking makes them lighter and less oily, but the crust won’t brown in quite the same way unless you use enough oil.
To bake them, place the coated patties on a parchment-lined baking sheet. Brush or spray both sides lightly with oil. Bake at 400°F until golden, flipping once halfway through. Watch them closely near the end so the breadcrumb coating doesn’t dry out too much.
An air fryer can also work. Lightly spray the patties with oil and cook until browned and firm. Turn them carefully partway through cooking.
How to store and reheat leftovers
These burgers taste best right after frying, when the outside is crisp. Still, leftovers are handy and reheat well.
Store cooled burgers in an airtight container in the fridge for up to 2 days. Place parchment between layers if stacking them.
To reheat, use a skillet, oven, or air fryer. A microwave works if you’re in a rush, but the coating will soften. For the best texture, warm them in a lightly oiled skillet over medium-low heat until hot and crisp again.
You can also make the mixture ahead. Cover the bowl and refrigerate it for a few hours, then shape, coat, and fry when ready. If the mixture thickens too much in the fridge, add a tiny spoonful of yogurt or a beaten egg spoonful. If it loosens, add breadcrumbs.
A light summer meal that still feels satisfying
These crispy zucchini and tuna burgers are the kind of recipe that proves simple food doesn’t have to be boring. They use humble ingredients, cook quickly, and hit that lovely balance of soft, savory, fresh, and crunchy.
Serve them hot, add new potatoes and parsley sauce, and you’ve got a meal that feels homemade in the best way.
