Key Ingredients You’ll Need

To make authentic and delicious Keto Tuna Melt Stuffed Peppers, gather these wholesome ingredients:

• 4 large bell peppers (any color) – Choose firm, evenly shaped peppers for consistent cooking.
• 1 can (5 oz) albacore tuna in water or oil – Drained thoroughly to avoid excess moisture.
• ½ cup full-fat cream cheese – Softened for easy mixing; adds richness and binds the filling.
• ¼ cup shredded sharp cheddar cheese – For that melty, savory kick.
• 2 tablespoons mayonnaise (preferably keto-friendly) – Adds creaminess without sugar.
• 1 tablespoon Dijon mustard – Brightens the flavor profile.
• 1 green onion, finely chopped – For freshness and a hint of oniony bite.
• Salt and black pepper to taste – Enhance without adding carbs.
• Optional: dash of garlic powder or paprika – For extra depth.

Step-by-Step Instructions

Follow these straightforward steps to prepare and bake your Keto Tuna Melt Stuffed Peppers:

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it.
2. Prepare the bell peppers: Cut off the tops and remove seeds and membranes. Stand upright on the cut side to create a stable base. Place on the baking sheet.
3. Make the tuna filling: In a medium bowl, combine drained tuna, softened cream cheese, mayonnaise, Dijon mustard, shredded cheddar, green onion, salt, and pepper. Mix until fully incorporated and smooth.
4. Stuff the peppers: Divide the tuna mixture evenly among the four peppers, pressing gently to fill each one completely.
5. Bake for 25–30 minutes, or until the peppers are tender and the filling is golden on top.
6. Optional broil: For a crispier top, switch the oven to broil for the last 2–3 minutes—watch closely to prevent burning.
7. Serve immediately with a dollop of sour cream or avocado slices for added richness.
