Make Ahead Instructions
To make these stuffed peppers ahead of time, make the filling, and store it in the fridge for up to two days. When ready to serve, bake the peppers, stuff them, and melt the cheese!
Variations
- Love spice? Use jalapeno peppers instead of bell peppers
- Don’t care about calories? Use mayo for a richer filling
- Use a different cheese for a different flavor profile! Mozzarella or Monterey Jack are great options.
- Use mini bell peppers and make appetizer-size stuffed peppers!
- Add more veggies like chopped carrots or green beans.
- Chopped pickles or capers can add a salty, briny twist!
Store Tuna Melt Stuffed Peppers
To store any leftovers or if you’re doing meal prep, let the stuffed peppers cool down completely, place them in an airtight container, and refrigerate for up to 3 days.
To melt the cheese again, simply place it under the broiler for a couple of minutes!
Freeze Tuna Melt, Stuffed Peppers,
It is recommended to freeze the stuffed peppers after baking them. Bake the cored, sliced peppers for 15 minutes, remove them from the oven, and pat them dry on the inside.
Stuff them with the tuna filling, sprinkle the cheese on top, and place in an airtight container. Freeze them for up to 3 months.
When ready to serve, let them thaw in the fridge overnight, stand at room temperature until completely thawed, and bake until the cheese melts.
