Make it spicy: Add a pinch of red pepper flakes or diced jalapeño for heat.

Prep in advance: You can fill the peppers a day ahead and refrigerate them, then bake just before serving.

Frequently Asked Questions

Can I Use Canned Tuna in Water Instead?

Yes, but oil-packed tuna adds more richness. If using water-packed tuna, consider adding a touch more olive oil for moisture.

What’s the Best Type of Bell Pepper to Use?

Red and yellow bell peppers are sweetest and pair well with the savory filling. Green peppers work too but have a slightly more bitter taste.

Can I Add Rice or Grains to the Filling?

Absolutely. Cooked rice, couscous, or quinoa can stretch the filling and add a hearty texture.

How Do I Know When the Peppers Are Fully Cooked?

The peppers should be tender but still hold their shape. A slight golden browning around the edges is a good sign they're ready.

Are Tuna-Stuffed Bell Peppers Healthy?

Yes! They're low in carbs, high in protein, and rich in vitamins A and C from the bell peppers.

How to Store

Allow the peppers to cool completely, then place them in an airtight container. Store in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F for 10–15 minutes or microwave on medium power until warmed through.

How to Freeze

To freeze, arrange the uncooked stuffed peppers in a single layer in a freezer-safe container. Wrap tightly with foil or plastic wrap and freeze for up to 2 months. Thaw overnight in the fridge before baking. If freezing leftovers, cool completely first, then store in airtight containers and consume within 1 month.

How to Make Tuna-Stuffed Bell Peppers

Preheat oven to 360°F (180°C). Line a baking tray with parchment paper.

Prepare the peppers: Cut off the tops and slice each bell pepper in half lengthwise. Remove seeds and white membranes.

Chop the tomatoes into small pieces and set aside.

Mix the filling: In a large bowl, combine the drained tuna, breadcrumbs, chopped cherry tomatoes, basil, salt, and pepper. Mix thoroughly until well combined.

Stuff the peppers: Arrange the pepper halves on the prepared tray. Spoon the filling generously into each half.

Drizzle the tops with extra virgin olive oil for added richness.

Bake for 30 minutes, or until the peppers are tender and the tops are lightly golden.

Serve warm, garnished with extra basil if desired.
