Red Bell Peppers Sweet red bell peppers act as the sturdy, colorful vessel for our filling. Additionally, roasting them mellows their bite and adds natural sweetness.

Canned Tuna Flaky canned tuna provides a high-protein base that absorbs herbs beautifully. Meanwhile, choosing tuna in olive oil adds maximum richness and moisture.

Parmesan Cheese Sharp Parmesan delivers a salty, nutty bite throughout the whole mixture. Consequently, it binds the filling while adding classic Italian flair.

Mozzarella or Feta Cheese Mild mozzarella creates an irresistible cheesy pull right over the top. Alternatively, tangy feta adds a sharp Mediterranean punch.

Garlic and Herbs Fresh garlic, basil, and dried oregano infuse every bite with aromatic warmth. Therefore, these classic spices completely transform humble canned fish.

Almond Flour or Keto Breadcrumbs A tiny sprinkling adds a subtle, satisfying golden crust on top. As a result, you get maximum texture without high-carb wheat breadcrumbs.

How to Make Italian Stuffed Peppers With Tuna

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

1. Slice four large red bell peppers in half lengthwise and remove the seed pods carefully.
2. Arrange the pepper halves cut-side up on a parchment-lined baking sheet.
3. Bake the plain pepper halves at 375°F (190°C) for 10 minutes until slightly tender.
4. Combine drained tuna, minced garlic, oregano, olive oil, and Parmesan in a medium bowl.
5. Scoop the savory tuna mixture evenly into each softened pepper half using a spoon.
6. Top each pepper generously with shredded mozzarella cheese and a light sprinkle of almond flour.
7. Bake at 375°F (190°C) for 18 minutes until the cheese is bubbling and golden brown.
8. Garnish immediately with freshly chopped basil leaves and sliced green onions before serving.

Pro Tip: Pre-roasting the empty pepper halves for ten minutes prevents excess moisture from pooling inside your finished filling.

Common Mistakes to Avoid:

• Skipping the pre-bake step: Putting raw filling into unbaked peppers results in crunchy, undercooked pepper shells.
• Using watery tuna: Drain your canned tuna thoroughly so your stuffed peppers do not turn soggy.
• Overfilling the peppers: Pack the tuna mixture gently to ensure even heating all the way through.
• Over-browning the top: Watch the cheese closely during the final five minutes to avoid burning the top crust.

Required Equipment:

• Rimmed baking sheet: Ensures even heat distribution while catching any natural roasting juices.
• Parchment paper: Prevents the peppers from sticking and makes cleanup virtually effortless.
• Medium mixing bowl: Allows plenty of room to combine the tuna, herbs, and cheese smoothly.
• Chef's knife: Makes slicing thick-walled bell peppers safe, quick, and neat.

Caleb's Recipe Tips

• Drizzle extra virgin olive oil: A light drizzle right before serving boosts rich Mediterranean flavor.
• Mix in chopped black olives: Adding sliced kalamata olives creates an authentic, salty Italian kick.
• Use fresh garlic cloves: Fresh minced garlic offers far better aroma than pre-jarred garlic paste.
• Add red pepper flakes: Sprinkle a pinch of crushed red pepper for a delightful hint of spicy heat.
• Garnish with fresh herbs: Fresh basil and green onions instantly brighten the rich, warm filling.

Storage Instructions

Store leftover stuffed peppers in an airtight glass container inside your refrigerator for up to four days. However, freezing is not recommended because bell peppers can become soft upon thawing. Meanwhile, reheat your leftovers in a 350°F oven for 12 minutes until warmed through. Alternatively, microwave individual peppers on medium power for two minutes for a fast lunch.
