Step 1

Place the tuna in a container. Add all the ingredients right over the fish, give it a quick toss, cover, and let it chill in the fridge for at least 4 hours- overnight is even better.

Step 2

Once it’s marinated, transfer the tuna into a small saucepan, strain the oil in, making sure the fish is snug and fully covered in oil.

Step 3

Bring it to a gentle simmer over medium heat and cook for about 5 minutes. Then, take it off the heat and let the tuna cool right in the oil for 30 minutes.

Step 4

You can use it immediately, or store it in the oil in the fridge for up to 5 days.

Step 5

In a bowl, gently crumble the tuna into chunky pieces. Add in the capers, diced celery, mayo, Calabrian chili, a pinch of salt, and black pepper. Mix everything together until just combined—be careful not to overmix, you want to keep those big, beautiful chunks of tuna intact.

Step 6

Slice the bagels in half and generously pile the tuna mixture on each half. Top each one with a slice of cheese, then pop them into the air fryer at 205°C (200°C) for 5-8 minutes, until the cheese is melted and golden and the bagels are perfectly crisp. Serve hot and enjoy!

YASSS!
