Super easy to make and fun to eat, these canned tuna nachos make a tasty appetizer or light dinner option. Cheesy, crunchy tortilla chips topped with juicy tuna, mashed avocado, diced onion, and fresh tomatoes, served on a sheet pan for easy sharing.

What Makes This Recipe So Good

  • These tuna nachos are super quick and easy. There’s only about 10 minutes of “cooking” to melt the cheese – the rest of the process is just piling up your toppings! Perfect if you need a delicious meal or snack on a tight schedule, or if you’re looking for something easy and low-effort to eat.
  • Tuna is packed full of protein, vitamins, and omega 3 fatty acids, making these nachos a fun and tasty way to get your nutrients in. If you want a real boost of protein, use 2 or 3 cans of tuna instead of just one.
  • Like all nachos, tuna nachos are totally customizable! Go with your favorite toppings, or use what ingredients you have on hand. You could even add some black beans, corn relish, a drizzle of your favorite hot sauce, or some spicy tomatillo red chili salsa.

Chef’s Tips

  • To keep the tortilla chips from getting soggy while they bake, you want to use a higher temperature and a shorter bake time. Remember – the goal here is just to melt the shredded cheese! It won’t take much time for that to happen.
  • You can easily adjust the portion size. For a single serving of tuna nachos, just dial back the quantities of each ingredient. You can use a quarter sheet pan instead of a full one, too. Feeding several people who each have their own topping preferences? Use individual round baking pans instead of sheet pans! You can dress up each serving as desired.
