Ingredients

• Bell Peppers: (4 large, various colors) – The vibrant vessels that hold our delicious filling. Different colors offer subtly varying flavors and visual appeal. Choose firm peppers for best results.
• Canned Tuna: (2 cans, 5 oz each, in water or olive oil, drained) – The protein powerhouse of our dish. Opt for tuna in water for a lower calorie option, or tuna in olive oil for richer flavor and healthy fats.
• Cooked Quinoa: (1 cup) – A nutritious and gluten-free grain that adds substance and fiber to the filling. Brown rice or couscous can be used as alternatives.
• Red Onion: (½ cup, finely diced) – Adds a pungent and slightly sweet flavor to the filling, enhancing the overall taste complexity.
• Celery: (½ cup, finely diced) – Provides a refreshing crunch and subtle savory note to the mixture.
• Carrot: (½ cup, finely diced) – Contributes sweetness and vibrant color, along with added nutrients.
• Frozen Peas or Corn: (½ cup) – Adds a touch of sweetness and texture, as well as extra vitamins and minerals. Feel free to use fresh or canned if preferred.
• Fresh Parsley: (¼ cup, chopped) – Lends a fresh, herbaceous aroma and flavor, brightening up the filling.
• Lemon Juice: (2 tablespoons) – Adds a zesty tang that cuts through the richness of the tuna and balances the flavors.
• Greek Yogurt or Light Mayonnaise: (¼ cup) – Acts as a binder and adds creaminess to the filling. Greek yogurt offers a healthier, higher protein option.
• Dijon Mustard: (1 teaspoon) – Contributes a subtle tang and depth of flavor to the tuna mixture.
• Garlic Powder: (½ teaspoon) – Enhances the savory notes of the filling with its aromatic punch.
• Paprika: (½ teaspoon) – Adds a mild smoky and slightly sweet flavor, as well as vibrant color.
• Black Pepper: (¼ teaspoon, freshly ground) – Seasons the filling and enhances the other flavors.
• Optional Toppings: (Shredded light cheese, fresh dill, hot sauce) – For added flavor and visual appeal at serving time.

Instructions

1. Prepare the Peppers: Preheat your oven to 375°F (190°C). Carefully wash the bell peppers and pat them dry. Slice each pepper in half lengthwise, from stem to bottom. Remove the seeds and membranes from each half, ensuring they are clean and ready to be filled. If you want the peppers to sit flat, you can slice a thin sliver off the bottom of each half, being careful not to cut through the pepper entirely.
2. Cook the Quinoa (if not already cooked): If you are using uncooked quinoa, follow the package instructions to cook it. Typically, this involves rinsing the quinoa and then simmering it in water or vegetable broth for about 15-20 minutes, or until the liquid is absorbed and the quinoa is fluffy. Ensure you have 1 cup of cooked quinoa for the recipe.
3. Prepare the Tuna Filling: In a medium-sized mixing bowl, combine the drained canned tuna, cooked quinoa, diced red onion, diced celery, diced carrot, and frozen peas or corn. If using frozen vegetables, you can thaw them slightly under warm water for a minute to speed up the cooking process in the oven, or add them frozen as they will cook through.
4. Add Flavor and Binding Agents: To the bowl with the tuna and vegetables, add the chopped fresh parsley, lemon juice, Greek yogurt or light mayonnaise, Dijon mustard, garlic powder, paprika, and black pepper. Mix everything together thoroughly until all ingredients are well combined and the tuna filling is nicely incorporated and slightly creamy. Taste the filling and adjust seasonings as needed – you may want to add a pinch more salt, pepper, or a dash of hot sauce if you like a little heat.
5. Stuff the Peppers: Using a spoon, generously fill each bell pepper half with the tuna mixture. Mound the filling slightly on top of each pepper half. Don’t be shy about filling them up, as the peppers will shrink slightly during baking.
6. Bake the Stuffed Peppers: Arrange the stuffed pepper halves in a baking dish. You can lightly grease the baking dish with cooking spray if desired, to prevent sticking. Add about ¼ cup of water to the bottom of the baking dish. This will create steam, helping the peppers to soften and cook evenly, and prevent them from drying out. Cover the baking dish tightly with aluminum foil.
7. Bake Covered: Bake the stuffed peppers in the preheated oven for 30 minutes, covered with foil. This initial covered baking allows the peppers to soften and the filling to heat through.
8. Bake Uncovered (Optional Cheese): After 30 minutes, carefully remove the foil from the baking dish. If you are using shredded light cheese, sprinkle it evenly over the top of each stuffed pepper at this point.
9. Bake Uncovered to Finish: Return the baking dish to the oven and bake for another 15-20 minutes, uncovered, or until the peppers are tender-crisp and the cheese is melted and lightly golden brown (if using cheese). The exact baking time may vary depending on the size and thickness of your bell peppers, so check for tenderness by piercing a pepper with a fork.
10. Rest and Serve: Once the stuffed peppers are cooked to your liking, remove them from the oven and let them rest for a few minutes before serving. This allows the filling to set slightly and the peppers to cool down enough to handle. Garnish with fresh dill or parsley if desired. Serve hot and enjoy!

These Healthy Tuna Stuffed Peppers are wonderfully efficient when it comes to preparation. The active prep time involves chopping vegetables, mixing the filling, and stuffing the peppers, all of which can be done in about 25 minutes, especially if you are efficient in the kitchen. The rest of the time is mostly hands-off baking, allowing you to relax or work on other tasks while dinner cooks in the oven. This makes it a fantastic option for a weeknight meal when you want something nutritious and delicious without spending hours in the kitchen. You can even prep the filling ahead of time and store it in the refrigerator until you’re ready to stuff and bake the peppers, further streamlining the process.

How to Serve

These Healthy Tuna Stuffed Peppers are quite versatile and can be served in various ways to create a complete and satisfying meal. Here are some serving suggestions:

• As a Main Course: Serve 1-2 stuffed pepper halves per person as the main dish. They are hearty enough to be a standalone meal, especially when paired with a light side.
• With a Fresh Salad: A simple green salad with a light vinaigrette dressing complements the richness of the stuffed peppers beautifully. Consider a mixed greens salad, a cucumber and tomato salad, or a spinach salad.
• Alongside Roasted Vegetables: Enhance the vegetable intake by serving the stuffed peppers with a side of roasted vegetables. Broccoli, asparagus, zucchini, or Brussels sprouts would be excellent choices. Roasting vegetables brings out their natural sweetness and adds another layer of flavor and texture to the meal.
• Over a Bed of Quinoa or Rice: For those who prefer a grain base, serve the stuffed peppers over a bed of fluffy quinoa or brown rice. This is especially good if you have leftover quinoa or rice. It adds extra carbohydrates and makes the meal even more substantial.
• With a Yogurt or Dill Sauce: A dollop of plain Greek yogurt or a light dill sauce (Greek yogurt mixed with fresh dill, lemon juice, and a pinch of salt) can add a cool and creamy element that complements the warm and savory stuffed peppers.
• As Part of a Buffet or Potluck: These stuffed peppers are also great for buffets or potlucks as they can be made ahead of time and are easy to serve. They are visually appealing and always a crowd-pleaser.
• Topped with Fresh Herbs: Before serving, garnish the stuffed peppers with extra fresh herbs like parsley, dill, or chives for added freshness and visual appeal.
• With a Side of Crusty Bread: For those who enjoy bread with their meal, a slice of crusty whole wheat bread or sourdough is a nice addition to soak up any delicious juices from the peppers and filling.

Additional Tips for Perfect Tuna Stuffed Peppers

1. Choose the Right Peppers: Select bell peppers that are firm and brightly colored. Different colored peppers not only add visual appeal but also have slightly different flavors. Red and yellow peppers are sweeter, while green peppers have a slightly more bitter taste. Ensure the peppers are stable and can stand upright when halved.
2. Don’t Overcook the Peppers: Bake the peppers until they are tender-crisp, not mushy. Overcooked peppers can lose their shape and become watery. Check for doneness by piercing a pepper with a fork; it should be easily pierced but still hold its shape.
3. Customize the Filling: Feel free to get creative with the filling ingredients. You can add other vegetables like chopped zucchini, mushrooms, or spinach. For added flavor, consider incorporating sun-dried tomatoes, olives, or capers. Spices like cumin, chili powder, or Italian seasoning can also be used to vary the flavor profile.
4. Use Quality Tuna: Opt for good quality canned tuna, whether it’s in water or olive oil. If using tuna in olive oil, you may want to reduce the amount of added fat in the filling by using less mayonnaise or Greek yogurt. Solid white albacore tuna or chunk light tuna both work well.
5. Make it Vegetarian/Vegan: To make this recipe vegetarian, you can easily substitute the tuna with cooked lentils, chickpeas, or crumbled tofu. For a vegan version, ensure you use plant-based mayonnaise or a vegan yogurt alternative, and consider nutritional yeast for a cheesy flavor if desired.
6. Make Ahead and Store: These stuffed peppers can be assembled ahead of time and stored in the refrigerator, unbaked, for up to 24 hours. This makes them perfect for meal prepping. When ready to bake, simply add about 10-15 minutes to the baking time to ensure they are heated through. Leftover baked stuffed peppers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
7. Spice it Up: If you like a bit of heat, add a pinch of red pepper flakes, a dash of hot sauce to the filling, or use a spicier variety of pepper like poblano or jalapeño peppers (though these will be spicier than bell peppers).
8. Freeze for Later: Baked stuffed peppers can be frozen for up to 2-3 months. To freeze, let them cool completely, then wrap each pepper half individually in plastic wrap and place them in a freezer-safe bag or container. To reheat, bake from frozen at 350°F (175°C) for about 40-50 minutes, or until heated through.

Frequently Asked Questions (FAQ)

Q1: Can I use different types of peppers?
A: Yes, you can definitely use different types of peppers! While bell peppers are classic and provide a good size and shape for stuffing, you can also use poblano peppers for a slightly spicier option, or even smaller sweet peppers for a bite-sized appetizer version. Just adjust baking time accordingly based on the pepper thickness.

Q2: What can I substitute for quinoa in the filling?
A: If you don’t have quinoa or prefer not to use it, brown rice, couscous, or even cooked barley are excellent substitutes. For a lower-carb option, you could also use cauliflower rice or finely chopped vegetables like zucchini or mushrooms to add bulk to the filling.

Q3: Can I make these stuffed peppers vegetarian or vegan?
A: Absolutely! To make them vegetarian, simply replace the tuna with cooked lentils, chickpeas, black beans, or crumbled firm tofu. For a vegan version, use plant-based mayonnaise or a vegan yogurt alternative, and consider adding nutritional yeast to the filling for a cheesy, umami flavor.

Q4: How do I prevent the peppers from becoming soggy?
A: To prevent soggy peppers, avoid overfilling the baking dish with water – a small amount is enough to create steam. Also, don’t overbake them; bake until they are tender-crisp. If you find your peppers are releasing a lot of liquid during baking, you can drain some of it off halfway through the cooking time.

Q5: Can I prepare the stuffed peppers ahead of time?
A: Yes, these are great for making ahead! You can prepare the filling and stuff the peppers up to 24 hours in advance. Store them covered in the refrigerator and bake as directed when you’re ready to serve, adding a bit of extra baking time to ensure they are heated through.

Q6: What are some good topping ideas for these stuffed peppers?
A: There are many delicious toppings! Shredded light cheese (cheddar, mozzarella, or Monterey Jack), a dollop of Greek yogurt or sour cream, fresh herbs like parsley, dill, or chives, a drizzle of hot sauce, or a sprinkle of toasted breadcrumbs all work wonderfully.

Q7: Can I freeze leftover stuffed peppers?
A: Yes, leftover baked stuffed peppers freeze well. Let them cool completely, wrap each half individually in plastic wrap, and then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months. Reheat from frozen in the oven for about 40-50 minutes at 350°F (175°C).

Q8: How can I make these stuffed peppers spicier?
A: To add some heat, you can incorporate a pinch of red pepper flakes, a dash of your favorite hot sauce, diced jalapeños (seeds removed for less heat), or use a spicier type of pepper like poblano for stuffing. You can also use a spicy mustard in the filling for an extra kick.
