Preparation Instructions
Follow these step-by-step instructions to create your perfect Tuna Melt Stuffed Peppers. The process is straightforward, ensuring you get a delicious and hearty meal with minimal fuss. Enjoy creating these wonderful Tuna Stuffed Bell Peppers that are sure to become a family favorite.
- Preheat Oven & Prepare Peppers: Preheat your oven to 375°F (190°C). Lightly grease a baking dish large enough to hold the bell pepper halves. Place the halved bell peppers, cut-side up, in the prepared dish. Bake for 10-15 minutes, or until they are slightly tender-crisp. This par-baking step helps soften the peppers without making them mushy. Remove from oven and set aside.
- Prepare Tuna Filling: While the peppers are par-baking, prepare the tuna filling. In a medium bowl, thoroughly flake the drained tuna with a fork. Add the mayonnaise, finely chopped celery, red onion, Dijon mustard, and garlic powder. Season with salt and black pepper to taste. Mix all ingredients well until everything is evenly combined and creamy.
- Stuff the Peppers: Carefully spoon the tuna mixture evenly into each par-baked bell pepper half. Don’t overfill, but ensure each pepper has a generous amount of filling.
- Add Cheese & Bake: Top each stuffed pepper with an even layer of shredded cheese. If you’re using breadcrumbs, sprinkle them over the cheese now for an extra crispy topping.
- Final Bake: Return the baking dish to the oven and bake for another 15-20 minutes, or until the bell peppers are completely tender and the cheese is beautifully melted, bubbly, and golden brown. For an extra golden crust, you can carefully broil for the last 1-2 minutes, watching closely to prevent burning.
- Serve: Carefully remove from the oven. Let them cool for a few minutes before serving hot. Garnish with fresh herbs if desired.

Fun Twists & Serving Ideas
- ✦ Spicy Kick: Add a pinch of red pepper flakes, a dash of hot sauce, or finely diced jalapeños to the tuna mixture for a zesty upgrade.
- ✦ Mediterranean Flair: Mix in chopped Kalamata olives, sun-dried tomatoes, and a sprinkle of dried oregano to the tuna, and top with crumbled feta cheese instead of cheddar.
- ✦ Garden Veggie Boost: Incorporate finely diced zucchini, corn, or peas into the tuna filling for added texture and nutrients.
- ✦ Smoky Flavor: A tiny bit of smoked paprika or a dash of liquid smoke in the tuna mixture can add a delicious depth.
- ✦ Herbaceous Delight: Experiment with fresh herbs like dill, chives, or parsley mixed into the tuna for different flavor profiles. Serve with a crisp green salad or a side of roasted sweet potatoes.

FAQ
Q: Can I prepare Tuna Melt Stuffed Peppers ahead of time?
A: Yes! You can prepare the tuna filling a day in advance and store it in the refrigerator. You can also par-bake the peppers and stuff them, then cover and refrigerate for up to 24 hours before baking. Add an extra 5-10 minutes to the baking time if baking from cold.
Q: What kind of tuna is best for this recipe?
A: Albacore tuna in water or oil is generally recommended for its firm texture and mild flavor. Make sure to drain it very well to avoid a watery filling.
Q: Can I use other vegetables instead of bell peppers?
A: While bell peppers are ideal for their shape and flavor, you could try this filling in hollowed-out zucchini boats or even large portobello mushroom caps for a similar effect.
Q: How do I store leftovers?
A: Store any leftover Tuna Melt Stuffed Peppers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
Q: Is this recipe gluten-free?
A: Yes, this recipe is naturally gluten-free as long as you don’t add any breadcrumbs or other gluten-containing ingredients. Always check your mayonnaise label to ensure it’s gluten-free.
