Ingredients
- 1 large sweet potato, scrubbed and sliced into 1/4-inch rounds (your crunchy, orange canvas)
- 1 can (5 oz) tuna in water, drained very well (the lean, protein star)
- 2 tbsp plain Greek yogurt (or light mayo for classic vibes)
- 1 tsp Dijon mustard (quiet zing, big flavor)
- 1 tbsp fresh lemon juice (brightens like a kitchen sunrise)
- 1 tbsp olive oil or avocado oil (for golden edges)
- 1 small celery rib, finely diced (crunch you can hear)
- 2 tbsp red onion, finely diced (a little sass)
- 1 tbsp capers, chopped (optional, salty winks)
- 1 tbsp fresh parsley, chopped (green confetti)
- 1/4 tsp garlic powder (garlic hugs)
- 1/4 tsp onion powder (backup singer to garlic)
- 1/4 tsp smoked paprika (optional, gentle campfire note)
- 1/4 tsp kosher salt (season like you mean it)
- 1/8 tsp black pepper (just enough attitude)
- 1 tsp hot sauce (optional, for brave hearts)
- 1 tsp everything bagel seasoning (optional, for finishing flair)
Instructions
- Preheat the air fryer to 390°F for 3 minutes. A warm basket means crisp edges and fewer potato tears.
- On the cutting board, slice the sweet potato into even rounds using a knife or a mandoline if you have it. Aim for coin-thick pieces so they cook evenly.
- In a mixing bowl, toss the rounds with oil, garlic powder, onion powder, salt, pepper, and smoked paprika if using. Use measuring spoons and a silicone brush to coat every surface.
- Lay a liner in the basket only if your air fryer manual says it’s safe. Arrange the rounds in a single layer with a bit of breathing room so air can actually fry.
- Air fry at 390°F for 10 minutes. Flip with tongs, then cook another 4–6 minutes until the centers are tender and the edges are golden.
- Meanwhile, open the tuna with a can opener and drain it like you mean it. In a bowl, mix tuna with yogurt, mustard, lemon juice, celery, red onion, capers, parsley, and hot sauce if you’re feeling bold.
- Mash the mixture with a fork until creamy but still textured. Taste and adjust with a pinch of salt, pepper, or a splash more lemon. That’s your flavor dial.
- Move the cooked rounds to a cooling rack for 2 minutes. This keeps them crisp instead of steamy and sad.
- Scoop a spoonful of the tuna mixture onto each round and gently press so it sticks. Sprinkle everything bagel seasoning on top if you want extra crunch and swagger.
- Return the topped rounds to the basket in a single layer. Air fry at 350°F for 2–3 minutes to warm the topping without drying it out, then plate and serve with a final whisper of lemon.
Substitutions
Need a couple of smart swaps so your kitchen life stays easy and delicious? Here are handy substitutions that keep the flavor strong.
- Use canned salmon instead of tuna for an omega-3 twist and a slightly richer taste.
- Swap Greek yogurt with light mayo or dairy-free yogurt for a creamy, dairy-free option.
- Trade fresh lemon with lime if that’s what your fruit bowl is rocking.
- No celery? Use finely diced cucumber or bell pepper for fresh crunch.
- Out of red onion? Try scallion or shallot for a milder bite.
- Skip smoked paprika and finish with a pinch of chili flakes for heat without the smoke.
- No everything bagel seasoning? Sprinkle toasted sesame seeds and a tiny pinch of garlic powder.
What to Serve With It
Pair with a bright side salad tossed in a lemony vinaigrette. The fresh greens make the rich tuna pop like a culinary exclamation point, and the textures play nice.
Add sliced cucumber or carrot sticks for extra crunch. A quick yogurt-herb dip keeps everything cool while the rounds bring the warm cozy energy.
For sips, try sparkling water with lemon or an iced green tea. Clean, zesty flavors let the sweet potato and tuna be the headliners, not the backup band.
What Else You Should Know
For make-ahead magic, mix the tuna topping up to 3 days in advance and keep it chilled. Slice the sweet potato earlier and store in cold water, then pat very dry before cooking so it actually gets crisp.
This snack is naturally gluten-free and pescatarian. Go dairy-free by using avocado oil mayo or a dairy-free yogurt, and pick a no-salt-added tuna if you’re watching sodium.
Leftovers keep in the fridge for 2 days. Re-crisp in the air fryer at 350°F for 3–4 minutes; the bottoms bounce back like a tiny edible trampoline.
No air fryer? Bake on a parchment-lined sheet at 425°F for 18–22 minutes, flipping once, then top and warm for 2–3 minutes.
Same vibe, slightly longer patience game.
