How to Make Avocado Tuna Melt Bagels
Step 1: Mix the Tuna Avocado Filling
In a medium mixing bowl, combine the drained tuna, mashed avocado, your choice of mayonnaise or Greek yogurt, Dijon mustard, lemon juice, garlic powder, black pepper, salt, diced red onion, and diced celery. Stir everything together until it’s well blended and looks creamy—taste and adjust the seasonings if you want a little extra zing or crunch. This vibrant blend is the star of your Avocado Tuna Melt Bagels, so don’t hesitate to sneak a little taste!
Step 2: Prep and Toast the Bagels
Lay your bagel halves, cut side up, on a baking sheet. Spread each half lightly with softened butter, if using. Pop them under your oven broiler for 1 to 2 minutes, keeping an eye out for that perfect golden edge. Toasting helps the bagels stand up to the filling and gives them a satisfying crunch.
Step 3: Assemble the Melts
Once your bagels are lightly toasted, spoon a generous layer of the tuna avocado mixture on each half. Top each with a ripe tomato slice and a piece of your chosen cheese. Don’t be shy—this is where the “melt” magic happens! Every bite should have a balance of creamy filling, juicy tomato, and oozy cheese.
Step 4: Broil Until Melty and Golden
Slide the assembled bagels back under the broiler for 2 to 3 minutes. Watch closely—this step goes quickly! You want the cheese to bubble and melt beautifully without overcooking the topping. When the cheese is gooey and slightly golden in spots, your Avocado Tuna Melt Bagels are ready for the table.
Step 5: Serve and Savor
Carefully remove the hot, melty bagels from the oven and let them sit for just a minute. This tiny bit of patience lets the cheese settle so the sandwich holds together perfectly when you take your first bite. Slice in half if desired, and enjoy the balance of flavors and textures you’ve created!
How to Serve Avocado Tuna Melt Bagels

Garnishes
For a finishing touch, sprinkle some freshly chopped parsley, chives, or even a dash of flaky sea salt on top of your Avocado Tuna Melt Bagels. A quick grind of black pepper or a few red chili flakes can also add zing! These little extras make each bite even more special—like the crown jewels atop your savory creation.
Side Dishes
Make a simple lunch feel like a full café experience by pairing your bagels with a bright green salad, a handful of sweet potato chips, or a tangy coleslaw. Even a bowl of fresh fruit or a crunchy dill pickle rounds out the meal beautifully without overshadowing the main event.
Creative Ways to Present
For a playful twist, serve the Avocado Tuna Melt Bagels open-faced on a big platter for a family-style meal, or cut them into quarters for party-ready finger food at brunches and gatherings. Stack them with extra veg, use a mix of different cheeses, or offer a “build your own” bagel bar for guests—they’re as fun to serve as they are to eat!
Make Ahead and Storage
Storing Leftovers
If you find yourself with extra Avocado Tuna Melt Bagels (which is rare!), wrap them individually and store them in an airtight container in the fridge. They’ll keep well for up to two days. The filling will soften the bagel over time, but the flavors meld beautifully for an even more intense bite.
Freezing
While the creamy avocado filling doesn’t love the freezer on its own, you can freeze the assembled (but not yet broiled) bagels if needed. Wrap each in foil and freeze for up to one month—just know the texture of the avocado may change slightly once thawed. For the very best results, enjoy them freshly made when possible.
Reheating
To reheat, simply pop the leftover melts on a baking sheet in a 350°F oven or under the broiler for a few minutes until the cheese is melty and the filling is warmed through. Avoid microwaving, which can make the bagel soggy and the filling unevenly heated.
FAQs
Can I use a different type Main Course, Lunch
Absolutely! While canned tuna is the classic choice, you can swap in canned salmon or even cooked, flaked chicken for a fun twist. Just make sure to adjust seasoning to complement your protein of choice.
What’s the best type of bagel for this recipe?
Everything bagels add an extra punch of flavor, but plain, whole wheat, or even sesame bagels all work beautifully. Just pick your favorite or whatever’s fresh from the bakery!
Is it possible to make Avocado Tuna Melt Bagels dairy-free?
Definitely! Use a plant-based cheese instead of regular cheddar or provolone, and swap the mayo for a vegan version. The avocado keeps things creamy and delicious, dairy or not!
Can I make the filling ahead of time?
The filling can be made a few hours in advance—just store it in the fridge and cover tightly with plastic wrap pressed against the surface to prevent the avocado from browning. Assemble and broil just before serving for maximum freshness.
How can I make my melts extra crispy?
For ultra-crispy Avocado Tuna Melt Bagels, toast the bagel halves until deeply golden before adding the topping, and broil them on the upper rack for an extra bubbly, browned cheese finish. You can even sprinkle a few breadcrumbs over the cheese for a little added crunch!
