How to Make Avocado Tuna Melt Bagels Recipe
Step 1: Prepare the Tuna Avocado Mixture
Start by draining the tuna well to avoid any watery mixture, then place it in a medium bowl. Mash the ripe avocado until smooth but still slightly chunky for texture. Add in the mayonnaise or Greek yogurt, Dijon mustard, and lemon juice to bring creaminess and zest. Sprinkle garlic powder, salt, and black pepper carefully to season. Finally, fold in the finely diced red onion and celery, which provide that perfect fresh crunch and bite.
Step 2: Toast the Bagels
Split the bagels in half and arrange them cut side up on a baking sheet. Lightly spread softened butter over each cut surface. Toast them under the oven broiler for 1 to 2 minutes until just golden and slightly crisp. This step ensures that the bagel holds up well to the toppings without getting soggy.
Step 3: Assemble the Bagels
Remove the toasted bagels from the oven carefully and spread the avocado tuna mixture evenly over each half, covering every corner. Lay a slice of fresh tomato on top of the tuna layer for juiciness and color. Then, add a slice of cheddar or provolone cheese to finish it off with creamy delight.
Step 4: Broil Until Melted
Return the assembled bagels to the broiler and cook for 2 to 3 minutes or until the cheese is bubbly, melted, and slightly golden. Watch closely to avoid burning. Once done, remove them promptly and let them cool just a bit before serving warm goodness.
How to Serve Avocado Tuna Melt Bagels Recipe

Garnishes
To really brighten up your Avocado Tuna Melt Bagels Recipe, try a sprinkle of fresh chopped parsley or chives on top. It adds a lovely pop of color and a subtle herbaceous note that pairs beautifully with the tuna and avocado. A dash of crushed red pepper flakes also works well if you enjoy a little heat.
Side Dishes
This sandwich shines alongside light and crisp sides. Think garden salads with a tangy vinaigrette, crunchy pickles, or even a bowl of warm soup on chilly days. Fresh fruit or roasted vegetables also complement the natural creaminess and balance out the protein-rich bagel melt.
Creative Ways to Present
For a fun twist, cut the finished bagels into smaller bites for a party platter or appetizer spread. You can also serve them open-faced or stack two halves for a heartier sandwich experience. Wrapping in parchment paper can make it portable for picnics, lunches on the go, or even a casual brunch.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftover Avocado Tuna Melt Bagels Recipe, store them in an airtight container in the refrigerator. They will keep their flavor and texture best for up to 2 days. For maximum freshness, consider storing the tuna avocado mixture separately from the toasted bagels and assemble just before eating.
Freezing
Freezing is generally not ideal for this dish due to the creamy avocado and fresh tomato, which can become watery and lose texture when thawed. However, you can freeze the toasted bagel halves alone for later use. Simply thaw and toast again before assembling with fresh tuna mixture.
Reheating
To reheat, it’s best to warm the assembled bagel melt under the broiler or in a toaster oven until the cheese melts again and the sandwich is heated through. Avoid microwaving, which may make the bagel soggy and the avocado less appetizing.
FAQs
Can I use canned salmon or chicken instead of tuna?
Absolutely! Canned salmon or chicken can be great substitutes, offering delicious variations on the classic melt. Just adjust seasoning to your taste and keep the creamy avocado base for that signature texture.
Is it better to use mayonnaise or Greek yogurt?
Both work well depending on your preference. Mayonnaise provides a richer, traditional creaminess, while Greek yogurt offers tanginess and reduces fat content. Feel free to blend both for a light but satisfying texture.
How do I pick the perfect avocado for this recipe?
Choose an avocado that yields slightly when gently pressed but isn’t mushy. This ensures it will mash smoothly while still retaining some texture, which is ideal for the tuna mixture.
Can I prepare the tuna mixture ahead of time?
Yes, you can prepare the tuna avocado mixture a few hours in advance and store it in the fridge. Just give it a gentle stir before assembling to redistribute the flavors and keep it fresh.
What type of cheese melts best for this recipe?
Cheddar and provolone are classic choices because of their meltability and flavor. Mozzarella or Monterey Jack are also delicious options if you prefer a milder cheese.

There’s something truly comforting about combining creamy avocado with flaky tuna and gooey melted cheese, all atop a perfectly toasted bagel.
