How to Make Tuna Stuffed Peppers

Preheat the Oven:
Set your oven to 425°F (220°C) to create a warm environment for baking those beautiful peppers.
Prepare the Peppers:
Carefully halve the green bell peppers and place them cut side up in a baking dish. Bake for 15 minutes until softened, creating the perfect vessel for your delicious filling.
Mix the Filling:
In a large bowl, combine Greek yogurt, lemon juice, Dijon mustard, salt, and pepper. Mix until smooth and creamy—this is where the flavor starts!
Add the Tuna:
Fold in the drained yellowfin tuna, chopped celery, and most of the green onions. Mix gently to keep the tuna intact and avoid a mushy filling.
Stuff the Peppers:
Once the peppers are ready, remove them from the oven. Stuff each halved pepper generously with the tuna mixture, getting that filling right to the top.
Top with Cheese:
Sprinkle shredded cheddar cheese over each stuffed pepper. This will melt and create a lovely, golden topping—yum!
Bake Again:
Return the stuffed peppers to the oven and bake for an additional 5 minutes, or until the cheese is melty and bubbly—an irresistible sight!
Serve and Enjoy:
Garnish with the reserved green onions and serve warm. Each bite is a celebration of flavor!

Optional: Serve with a light green salad or warm pita bread for a complete meal.

Expert Tips for Tuna Stuffed Peppers

Choose Quality Tuna: Always opt for high-quality, oil-packed yellowfin tuna to enhance flavor and moisture in your filling.
Blanch Bell Peppers: Pre-cook your green bell peppers by blanching them for a few minutes. This ensures they are tender yet firm, avoiding mushiness.
Proper Draining: Always make sure your tuna is well-drained before mixing to prevent a soggy filling.
Don’t Skimp on Yogurt: Using the right amount of Greek yogurt is crucial for achieving a creamy and flavorful filling—this is where the richness comes from!
Let the Filling Rest: Allowing the tuna mixture to rest for about 15 minutes before stuffing gives time for flavors to meld deliciously.

Tuna Stuffed Peppers Recipe FAQs

How do I choose the right bell peppers for this recipe?
Absolutely! When selecting bell peppers, look for ones that are firm to the touch, brightly colored, and free of blemishes. If you notice dark spots all over, it’s best to choose another. Green peppers provide a wonderful flavor contrast, but feel free to experiment with yellows, reds, or oranges for added sweetness and visual appeal!

How should I store leftover Tuna Stuffed Peppers?
After enjoying your delicious meal, store any leftovers in an airtight container in the fridge where they will stay fresh for up to 3 days. Just remember, they should not be left at room temperature for more than 2 hours. To reheat, pop them in the oven at 350°F (175°C) until they’re warm throughout—this keeps the peppers tender without sacrificing flavor.

Can I freeze Tuna Stuffed Peppers?
Very! You can freeze unbaked Tuna Stuffed Peppers for up to 2 months. To prepare for freezing, wrap each pepper in plastic wrap and place them in a sealed container. When you’re ready to enjoy them, simply thaw overnight in the fridge and bake at 425°F (220°C) for around 20-25 minutes, or until the cheese is bubbly. This way, you still get that fresh and delightful flavor!

What should I do if my filling is too dry?
If your filling seems dry, don’t worry—it’s a common issue. You can add a bit more Greek yogurt to the tuna mixture for moisture. Additionally, ensuring your tuna is well-drained and evenly mixing the Greek yogurt will help maintain that creamy texture. If you prefer, adding a splash of lemon juice can also lend a beautiful zing and moisture!

Are there any dietary considerations I should keep in mind?
If you have dietary restrictions or allergies, it’s easy to adapt the recipe. For instance, if you’re avoiding dairy, skip the cheddar cheese or use a dairy-free alternative. Loving pets? Keep in mind that tuna can be high in mercury; it’s best to avoid giving it to your furry friends. Always check ingredients for allergens and see what fits best for your family’s needs.

Can I make the filling in advance?
Absolutely! I often prepare the filling ahead of time. Mix it up in the morning or even a day before, then store it in the fridge until you’re ready to stuff the peppers. This way, not only do you save time, but the flavors have a chance to meld together, making your Tuna Stuffed Peppers even tastier when it’s time to bake!
