Keto Tuna Melt

Stuffed Zucchini With Tuna
Have you ever made zucchini boats before? This stuffed zucchini is basically the same idea. You will need to scoop out the seeds from the middle of the zucchini first. Then you’ll have a little boat. Fill it up with your tuna mixture.

This is a mild recipe that is perfect for kids. Amp up the spice and the flavor by splashing a little hot sauce into the tuna mixture. Or, sprinkle some Everything Bagel seasoning on top after you pull it out of the oven.
Keto Stuffed Zucchini
You can make this keto stuffed zucchini in the oven or your air fryer. The directions to make stuffed zucchini in the air fryer are similar to the baking instructions.

Place the stuffed zucchini in your air fryer basket. Air fry it at 400F for about 10 minutes. Add more cheese and bake for 10 more minutes.
Since all air fryers are different, check on it during the last 5 minutes to make sure it didn’t burn or overcook.
Zucchini For Lunch
This is such a quick and easy lunch that you won’t have to meal prep it. To speed up the meal prep time, you can slice the zucchini, remove the seeds, and then wrap it in plastic wrap and keep it in the refrigerator until you are ready to use it.

What To Eat With Zucchini
This cheesy tuna and zucchini will fill you up. It’s a quick and cheap lunch that’s also really nutritious and good for you!

Serve it with a salad like strawberry cucumber salad. The sweet strawberries and crunchy cucumbers are a perfect contrast to the soft and savory zucchini.
If you are eating it for dinner, serve with loaded cauliflower mash. This is a creamy and fiber-rich side dish.
Keto breadsticks will also taste delicious with the stuffed zucchini, especially if you have a family that loves carbs.
