Tuna & Spinach Stuffed Banana Peppers
Try this unexpected and delicious use of tuna for a light lunch or appetizer.
Ingredients
filling:
- 5 oz can albacore tuna in water, drained
- 8 oz cream cheese at room temperature
- 1/4 cup shredded mozzarella
- 2 oz baby spinach, steamed, drained and cooled
- 3 tablespoons minced red onion
- 1/2 tablespoon nonpareil capers
- 1/2 teaspoon crushed red pepper flakes
- 1/2 teaspoon dried oregano
- freshly ground black pepper
the peppers:
- 8 banana peppers, halved with ribs and seeds removed
- shredded mozzarella for sprinkling about 1/8 cup
Instructions
- Preheat oven to 400. Line a baking sheet with parchment, set aside.
- In a large bowl, mix together the filling mixture with a spoon or mixer until a fairly uniform mixture forms.
- Place the peppers cut side-up on the lined parchment. Fill with tuna mixture until it is roughly level with the sides of the pepper. Sprinkle with cheese. Bake 7-10 minutes or until browned and bubbly. Cool for 5 minutes prior to serving.
- Cool for 5 minutes prior to serving. Use a spatula to lift them out of the pan. Don't use tongs! Ask me how I know!
Notes
- Banana peppers can be unexpectedly spicy! Take care to wash your hands thoroughly after handling.
- Frozen, chopped spinach is a great sub for fresh, just drain it thoroughly.
- Cutting a tiny slice out of the bottom of the pepper can help it keep it from rolling around on the pan as you lift it in and out of the oven--I didn't have this issue with these peppers but I have with other peppers in the past.
- The leftover filling is great on crackers.

I came up with a ton of fun ideas for my (yet unsold!) tinned seafood cookbook that I never actually made. I made the recipes I included in the actual proposal, of course, but I have the whole notebook of other recipe ideas and notes using everything from tuna to canned octopus in really fun and sometimes unexpected ways.
A lot of the recipes were deliberately planned around using ingredients anyone could easily find and probably already have around the house. These ideas are really coming in handy for me now when I am trying to shop less and we are making every meal we eat (nearly 140 days and counting!).
We get a produce delivery of all local produce from various farms and right now we can’t choose what we get–normally the real perk of the service is that you can swap out any item in the box for something else they have in stock but right now we are at the mercy of what they give us. It’s not a CSA so we don’t end up with a box of just kale but it’s limited to what’s in season and/or available. Which is fine, it’s a pandemic, it’s understandable but I do end up with ingredients I would never willingly choose.
I’m not sure I even have had a fresh banana pepper before–we are hot pepper fans–but we ended up with a bag. I got a few good suggestions on Instagram (including a pork chop-pineapple combo that sounds amazing and I am filing away for later) but since it is not my week to go to the grocery store and these peppers aren’t going to last forever, I had to improvise.
Can this recipe also use sweet bell peppers and taste ok?
I have not tried it but I think it would taste okay. I would maybe try quartering the peppers and filling them like little boats.
