Tuna Melt Poppers are fun little bites that pack a lot of flavor! Made with fluffy bread, tasty tuna, and gooey cheese, they’re perfect for a quick snack or party treat.
I love how easy they are to make. You just mix up the tuna filling, stuff it in the bread, and pop them in the oven. Plus, who can resist that melted cheese? Yum! 🧀
Key Ingredients & Substitutions
Red Bell Peppers: These lend great color and sweetness! If you don’t have red, green or yellow peppers work, too. Just note that green peppers have a more bitter taste.
Tuna: Canned tuna makes this dish easy and quick. You can substitute with canned salmon or even chickpeas for a vegetarian option!
Mayonnaise: It adds creaminess. You can swap it for Greek yogurt or vegan mayo if you want a lighter or dairy-free version.
Dijon Mustard: This brings a nice tang. If you’re out, regular mustard will work. You can also use a touch of hot sauce for some kick!
Cheddar Cheese: I love using sharp cheddar for its rich flavor. You can use mozzarella or Monterey Jack if that’s what you have on hand.
How Do You Get the Perfect Tune Filling Consistency?
Getting the right tuna filling consistency is crucial for those poppers. You want it creamy but not too runny. Here’s how to achieve it:
- Start with drained tuna. Make sure all excess liquid is removed.
- Add just enough mayonnaise to help bind the mixture together. Too much can make it soggy.
- Mix in your chopped veggies lightly. They add crunch but don’t overpower the tuna!
- Taste your mixture before filling the peppers – adjust seasoning if needed!

For the Poppers:
- 2 medium red bell peppers
- 1 can (5 oz) tuna in water, drained
- 1/4 cup mayonnaise
- 1 tablespoon Dijon mustard
- 1/4 cup finely chopped celery
- 1/4 cup finely chopped onion (red or yellow)

Timing: How Much Time Will You Need?
This recipe takes about 10 minutes to prep and around 10-12 minutes to cook, making it quick and easy to whip up a delicious snack or appetizer in just 20-25 minutes!
Step-by-Step Instructions:
1. Preheat and Prepare Your Peppers:
Start by preheating your oven to 375°F (190°C). While that’s warming up, wash the red bell peppers. Cut them in half lengthwise and carefully remove the seeds and membranes. Place them aside for later.
2. Mix the Tuna Filling:
In a medium bowl, combine the drained tuna, mayonnaise, Dijon mustard, chopped celery, chopped onion, lemon juice, garlic powder, salt, and black pepper. Stir everything together until well mixed—you want it creamy and tasty!
3. Stuff the Peppers:
Spoon the tuna mixture evenly into each bell pepper half. Don’t be shy—fill them up good!
4. Add the Cheese:
Place the stuffed pepper halves on a baking sheet or an oven-safe tray. Generously sprinkle shredded cheddar cheese over the top of each stuffed pepper. More cheese means more flavor!
5. Bake:
Put your peppers in the preheated oven and bake for about 10-12 minutes. You’ll know they’re ready when the cheese is melted and bubbly.
6. Cool and Garnish:
Once done, take them out of the oven and let them cool slightly. Then, garnish with fresh chopped parsley or chives to brighten up the dish.
7. Serve and Enjoy!
These tasty Tuna Melt Poppers are perfect for snacking, as an appetizer, or even as a light meal. Serve them warm and enjoy every bite!
Can I Use Different Types of Peppers?
Absolutely! While red bell peppers are sweet and perfect for this dish, you can use green or yellow bell peppers as well. Just keep in mind that green peppers have a more bitter flavor that some may not prefer.
What Can I Use Instead of Mayonnaise?
If you’re looking for a lighter option, Greek yogurt works great as a substitute for mayonnaise. You can also use avocado for a creamy texture, or vegan mayo for a plant-based alternative!
How Do I Store Leftover Tuna Melt Poppers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, simply warm them in the oven at 350°F (175°C) for about 5-7 minutes to restore the cheese’s melty goodness!
Can I Make These Poppers in Advance?
Yes, you can prepare the stuffed peppers ahead of time! Just assemble them without baking, cover, and refrigerate. When you’re ready to cook, add a few extra minutes to your baking time.
