    Tostada de Atún (Tuna Tostada) is a budget-friendly, light, and delicious recipe. Ready in minutes, this Mexican dish is a great meal for busy weeknights.

    Watch the VIDEO or follow the step-by-step tutorial below to make this yummy recipe at home.

    Tostada de Atún on a wooden surface surrounded by avocado, cilantro, and a decorative blue plate.

    I’m all about cheap, easy, and delicious recipes. I feed two guys – my husband and my son. Let me tell you… my guys can eat!

    To top that off, they both can be very picky.

    This recipe for Tostada de Atún (Tuna Tostada) will not break the bank, light and healthy, and best of all, I know my guys will like it.

    Ingredients for Tostada de Atun Tuna Tostada on a wooden surface.

    How to Make Tostada de Atún (Tuna Tostada)

    These are the ingredients for Tostada de Atún (Tuna Tostada).

    What I love about these ingredients is that it uses canned tuna, and it is extremely forgiving.

    Say you don’t have cucumbers. No problem. No avocado? That’s cool too. Adjust with whatever you have in your fridge.

    • If you have pico de gallo already made, putting this recipe together will take no time at all.

    Two opened cans of tuna from Trader Joe's, one slightly in front of the other.

    I am using canned tuna from Trader Joe’s. We always, always have this in the pantry.

    This is canned albacore tuna, but you can also use regular tuna. Just make sure it’s in water and drained well.

    This recipe is wet enough. You don’t want more liquid than necessary.

    In my humble opinion, the tuna that is in oil is very oily.

    Key Limes and Lime Juicer on a granite counter.

    You will need a lot of lime juice. I tend to use key limes because that’s mostly what we use in Mexico.

    Next time you’re at the grocery store, price compare them with regular lime. Key limes are, in most cases, cheaper.

    If limes aren’t in season or you simply can’t find them, yellow lemon works well too.



    Here’s a trick: If you don’t have enough lime juice, you can use a mixture of lime juice and white distilled vinegar.

    Ingredients for a tuna tostada in a glass container.

    Seriously guys, this recipe for Tostada de Atún (Tuna Tostada) is a no brainer.

    Put all the ingredients in a container and mix well.

    I added pickled onions. If you don’t have any, you can also use red onion or green onion.

    Another thing that you don’t see in the video is that I added the juice from the pickled onion. I like the tuna mixture to be extra tangy.

    That is totally up to you.

    Other ingredients you can add to your Tostada de Atún (Tuna Tostada):

    • Diced Mango
    • Pineapple
    • Diced green beans (cooked)
    • Peas (cooked)
    • Shredded Carrots
    • Diced Asparagus (cooked)
    • Thinly sliced Jicama
    • Corn kernels
    • Pickled jalapeño instead of fresh jalapeño
    • Olives
    • Capers

    If you go for the pickled jalapeño and like spicy food, here’s a yummy suggestion:

    • Pour some of the pickling juice in the tuna mixture. Just a little. About 1 tablespoon or so.

    It will give the tuna a spiciness that’s super tasty.

    Salpicon de Atun (or Tuna Mixture) in a glass container.

    Look at all the colors! Do you see why I say make this for a party? You can even entertain with this dish.

    Tostada de Atún (Tuna Tostada) is a light but flavorful dish. I can easily eat two tostadas.

    • Some people also call this recipe Salpicón de Atún because of all the lime juice. It is very similar to Salpicón de Res but with tuna.

    Make enough for the next day. In my humble opinion, it tastes even better the next day and once it’s had time to absorb all the flavors.

    Time to assemble the Tostada de Atún (Tuna Tostada)

    Personally, I like to add a thin layer of refried beans as the base.

    It serves as bed for all the ingredients to sit, almost like a glue.

    Instead of Refried Beans, you can also use:

    • Mayonnaise
    • Guacamole
    • Crema Mexicana
    • Sour Cream
    • Chipotle Mayo Sauce

    If you do not have tostada shells, you can eat the tuna mixture with saltine crackers as an appetizer.

    Also, if you have corn tortillas, you can make homemade tostadas. Simply bake them in the oven or fry them.

    For a keto friendly, low carb, healthy option, try serving the tuna mixture with a salad.

    Two Tuna Tostadas (or Tostadas de Atun) surrounded by cilantro and queso fresco.

    Top off the tostada with the tuna mixture, queso fresco, and avocado slices.

    You can also add sour cream or crema mexicana. Some people will also top with hot sauce, shredded lettuce, or shredded cabbage.

    I highly suggest serving immediately after assembling the Tostada de Atún. The tuna mixture is wet and will make the tostada limp and soggy. No bueno.

    I am on Pinterest all day long. Find me on Pinterest.
    Don’t forget to pin this recipe for later.

    The tuna mixture will last for up to 3 days in the refrigerator. This is great news for my fellow party throwers.

    Serve your guests a Tostada de Atún at your next party. It’s so yummy that they will never know it is an economically-friendly dish.

    However, just be sure to keep the serving container cold. You don’t want to get anyone sick.

    Make it ahead of time, and enjoy the party. It also transports well. So, it is great for a potluck lunch at work.

    • I do not recommend freezing this at all. Think frozen fish… EEK!

    This is an authentic Mexican dish that is served during Lent, Easter events, or whenever someone is hungry. LOL. Hope you and your family enjoy!
