We’ve come to really appreciate the plain tuna fish sandwich as a gateway for toddlers into the world of sandwiches; it is also, we must admit, a little soft. The texture is one-note; the taste is basically the same: squish. Easy for a young child to get into, sure; easy enough, eventually, to grow out of.
So we’ve literally leveled up the tuna sandwich for kids to match the needs of older toddlers and school-aged children, keeping what makes it so accessible and tricking it out until it’s downright incredible. Texture? It’s got crunch for days. Depth? It’s got vegetables integrated into it. Delicious? Totally. You’ll know it as soon as you have a bite, if not from simply reading the ingredients below: it has that same slightly-sweet, slightly-browned (if you know what I mean) flavor of a certain golden-arched fast food chain, with a silky texture and insistent cheesiness. So good, in fact, it’s become a weekend ritual in our house–and soon, we hope, to be one in yours.
(Shoutout to this amazing restaurant for the inspo!)
Ingredients Overview
This upgraded tuna sandwich for kids builds flavor and texture by layering finely diced vegetables, a seasoned mayo mixture, and high-quality tuna. The pickles, onion, and celery create the signature crunch; the paprika, garlic powder, onion powder, dill seed, and lemon add depth; and the cheese plus optional potato chips transform the classic tuna filling into something with real structure and substance. Pure comfort food.
Steps Summary
- Dice the pickles, onion, and celery into very small pieces.
- Stir together the pickle pieces with mayo, paprika, garlic powder, onion powder, dill seed, and lemon; slowly whisk in the olive oil.
- Add drained tuna plus the diced onion and celery; mash and mix until fully integrated. Chill at least 30 minutes.
- Toast buttered/mayo’d bread in a pan, melt cheese on top, and cook to a golden brown.
- Spread tuna on the melted cheese, add potato chips for crunch, top with a second slice, and smash gently to meld. Cut diagonally and serve.
FAQ
Can I make the tuna mixture ahead of time?
Yes. The tuna mixture actually improves as it rests; refrigerating it for 30 minutes—or even all day—helps the flavors meld and the texture firm up.
My child struggles to hold sandwiches. What should I do?
Because this sandwich is intentionally messy and packed, younger children may need help gripping it. Show them a two-handed hold or serve just the tuna-and-cheese slice folded like a taco.
Can I add other toppings?
If your child already likes additions on their tuna sandwiches—like thin cucumber slices—feel free to add them here. The base mix is flexible.
Can I adapt this method for other recipes?
Yes. The same approach works well for any mayo-based salad, such as chicken or whitefish salad. For younger toddlers, you can even spread the mixture on crackers with a small cheese square.

Instructions
Prep
-
Dice the pickles, onion, and celery into the smallest pieces possible. (Think the size of the onion bits on a McDonald’s hamburger.).
-
In a bowl, add the pickle pieces, mayo, paprika, garlic powder, onion powder, dill seed, and a big squeeze of lemon; combine. Pour the olive oil into the bowl slowly, stirring rapidly as you do; continue until everything is integrated.
-
Open cans of tuna and empty water out of them; add tuna piece, along with onion and celery pieces, to the bowl. Mash and stir tuna until broken up and mixed with the rest of the bowl. Refrigerate for at least 30 minutes, if not all day.
Cook and Assemble
-
When ready to make the sandwich, slather mayo or butter on one side of each piece of bread you are using. Heat a large pan to Medium Low to start; once hot, place the bread slices into the pan butter/mayo side down, then add a slice of cheese on top of the bread. Once the cheese begins to soften and/or melt, raise the heat to Medium and cook until the pan side of the bread is golden brown. Remove from heat.
-
Spread the tuna fish on top of the melted cheese on half of the bread slices; add 3-4 potato chips on top of the tuna. Place the remaining un-tuna’d bread slices on top of the ones with the tuna and chips and smash down to meld. Cut diagonally.
Serve
-
Because this is a messy, sloppy sandwich, your child may struggle a bit to hold on to it and/or keep the contents from spilling out; you may need to show them how to two-hand the thing. Another option is to only serve them the slice of bread with the tuna on top, which you can fold up like a taco. If your child is accustomed to other toppings on his/her tuna sandwich, feel free to add to the sandwich before serving. (Pro tip: our son swears by thin cucumber slices in it.)
Adapt
-
You can apply the same approach to basically any mayo-based “salad”--say, whitefish or chicken salad–and it’ll do just fine. For a less fussy approach–at least for a small child, anyway–you can top a cracker with a small square of cheese and a smear of the tuna
