Key Ingredients
Ingredient Notes
Zucchinis. Zucchini makes the perfect boat when hollowed out to hold all your favorite fix-ins. It’s low-carb so that you can have the perfect keto zucchini boats.
Canned tuna. Not only is canned tuna cost-effective, but it’s also a high-quality isolated source of protein. Canned tuna works great for a keto tuna melt or even tuna salad.
Mayo. There is a variety of different mayos. For the best flavor, choose the quality one made with olive oil instead.
Olives. Olives are an uncommon but delicious addition to tuna. They are salty, tender, and super flavorful. Try using stuffed or marinated olives for even more of a punch.
Shredded Irish cheese. It doesn’t have to be Irish cheese, but it certainly adds a kick!

2. Fill zucchinis with tuna mix, sprinkle with cheese. Bake for 12-15 minutes till cheese is melted and slightly golden.
Recipe Tips
It’s not often you find a low-carb version of a meal that tastes as good as original, but these keto zucchini boats with tuna are sure to give traditional tuna melts a run for their money!
Some of our key tips to have cooking success with tuna stuffed zucchini boats are to:
Broil the zucchini boats on low for a few seconds for extra golden and crispy cheese.
Don’t be afraid to customize. If you love celery, black pepper, onion, etc., in your tuna melts, feel free to add them in.
If your tuna seems dry, simply add a little extra mayo.
Buy tuna canned in water. Avoid low-quality oils like cottonseed or soybean by purchasing tuna packed in water. You can always add your own olive oil back in later.
