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!

How to Make It

1. Gather the ingredients—Preheat oven to 375F degrees. Wash and clean zucchinis by scooping out the insides with a spoon—mix drained tuna with mayo and quartered olives and salt.

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.
