• Diced Tomatoes: 1 can (15 ounces) fire-roasted diced tomatoes, undrained
• Spices:
  • 2 teaspoons chili powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon dried oregano
• Seasoning: 1 teaspoon salt (or to taste), 1/2 teaspoon black pepper
• Fresh Cilantro: 1/2 cup, chopped, plus more for garnish

• Cheese: 1 ½ cups shredded cheese (Monterey Jack, cheddar, or a Mexican blend)
• Water for Baking Dish: 1/2 cup

Step-by-Step Instructions

Follow these detailed instructions to ensure your stuffed peppers are cooked to perfection, with a tender pepper shell and a flavorful, moist filling.

1. Prepare the Bell Peppers:

• Preheat your oven to 400°F (200°C).
• Wash the bell peppers thoroughly. Slice each pepper in half lengthwise, from stem to bottom.
• Carefully remove the seeds, white membranes, and stems. You want to create a clean, boat-like vessel for the filling.
• Place the pepper halves, cut-side up, in a large 9×13 inch baking dish. Drizzle them lightly with 1 tablespoon of olive oil and a pinch of salt and pepper. This pre-seasoning step adds flavor directly to the pepper itself.
• Pour the 1/2 cup of water into the bottom of the baking dish. This creates steam as the peppers bake, helping them to soften and preventing the bottoms from scorching.
• Bake the empty pepper halves for 15-20 minutes while you prepare the filling. This pre-baking step, or “par-baking,” is crucial for ensuring the peppers are tender and not unpleasantly crunchy in the final dish.

2. Cook the Quinoa:

• While the peppers are in the oven, cook the quinoa. It’s essential to rinse the quinoa under cold water in a fine-mesh sieve for at least 30 seconds. This removes the natural saponin coating, which can give it a bitter or soapy taste.
• In a medium saucepan, combine the rinsed quinoa and 2 cups of vegetable broth (or water). Using broth instead of water infuses the quinoa with a deep, savory flavor from the very start.
• Bring the mixture to a boil over high heat. Once boiling, reduce the heat to low, cover the saucepan with a tight-fitting lid, and let it simmer for 15 minutes, or until all the liquid has been absorbed.
• Remove the saucepan from the heat and let it stand, still covered, for 5 minutes. This allows the quinoa to steam and finish cooking.
• After 5 minutes, fluff the quinoa with a fork. You should have perfectly cooked, separate grains. Set aside.

3. Create the Savory Filling:

• In a large skillet or Dutch oven, heat the remaining 1 tablespoon of olive oil over medium heat.
• Add the finely chopped yellow onion and sauté for 5-7 minutes, until softened and translucent.
• Add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic, as it will become bitter.
• Stir in the chili powder, ground cumin, smoked paprika, and dried oregano. Toast the spices in the pan for about 30 seconds until they become very fragrant. This step “blooms” the spices, deepening their flavor.
• Add the rinsed and drained black beans, the corn, and the can of fire-roasted diced tomatoes (with their juices). The fire-roasted tomatoes add a wonderful smoky depth that regular diced tomatoes don’t have.
• Stir everything together to combine and bring the mixture to a gentle simmer. Let it cook for 5 minutes, allowing the flavors to meld together.

4. Combine and Finalize the Filling:

• Turn off the heat. Add the cooked, fluffed quinoa to the skillet with the bean and vegetable mixture.
• Add the chopped fresh cilantro and the fresh lime juice. The cilantro adds a burst of freshness, and the lime juice brightens all the savory flavors.
• Stir in 1/2 cup of the shredded cheese. This makes the filling extra creamy and helps it bind together.
• Mix everything until well combined. Taste the filling and adjust the seasoning if necessary, adding more salt and pepper to your preference.

5. Stuff and Bake the Peppers:

• By now, your par-baked pepper halves should be ready. Carefully remove the baking dish from the oven.
• Generously spoon the quinoa and black bean filling into each pepper half. Don’t be shy—mound it up!
• Cover the baking dish tightly with aluminum foil. This traps the steam and ensures the peppers cook through evenly without the filling drying out.
• Return the dish to the 400°F (200°C) oven and bake for 20-25 minutes.

6. The Final Cheesy Melt:

• After 20-25 minutes, carefully remove the aluminum foil.
• Sprinkle the remaining 1 cup of shredded cheese evenly over the top of the stuffed peppers.
• Return the dish to the oven, uncovered, and bake for an additional 10-15 minutes, or until the cheese is completely melted, bubbly, and slightly golden brown on the edges.
• Let the stuffed peppers rest in the baking dish for 5-10 minutes before serving. This allows them to set slightly, making them easier to serve and allowing the flavors to settle. Garnish with extra fresh cilantro before bringing them to the table.

How to Serve

These stuffed peppers are a fantastic all-in-one meal, but they also pair beautifully with a variety of sides and toppings to create a more elaborate feast. Here are some serving suggestions:

• Toppings Bar: Set out small bowls of toppings so everyone can customize their pepper. Great options include:
  • A dollop of sour cream or plain Greek yogurt for a creamy, tangy contrast.
  • Sliced or diced avocado for extra creaminess and healthy fats.
  • Your favorite salsa or pico de gallo for a fresh, zesty kick.
  • A few dashes of hot sauce for those who like extra heat.
  • A sprinkle of crumbled cotija cheese for a salty finish.
  • Extra chopped fresh cilantro.
• Side Salads: A light, refreshing salad is the perfect counterpart to the warm, savory peppers.
  • Simple Green Salad: A bed of mixed greens with a simple lime vinaigrette.
  • Avocado and Tomato Salad: Diced avocado, cherry tomatoes, red onion, and cilantro tossed with lime juice.
  • Corn and Jicama Salad: A crunchy and sweet salad that complements the flavors in the filling.
• With a Grain or Bread:
  • Serve alongside a scoop of Cilantro Lime Rice to catch any extra filling.
  • Warm corn tortillas or crusty bread are perfect for scooping up the cheesy, saucy goodness at the bottom of the pan.
• As Part of a Larger Spread:
  • For a dinner party or potluck, serve these peppers alongside other Tex-Mex-inspired dishes like seven-layer dip, chips and guacamole, or a black bean and corn salsa.

Additional Tips for Stuffed Pepper Perfection

1. Toast Your Quinoa: For an extra layer of nutty, complex flavor, toast your rinsed and dried quinoa in a dry saucepan over medium heat for 3-5 minutes before adding the liquid. Stir constantly until it becomes fragrant and makes a soft popping sound. This small step significantly enhances the taste of the entire dish.
2. Choose Your Peppers Wisely: While any color bell pepper works, they each offer a slightly different flavor profile. Red, orange, and yellow peppers are sweeter and tend to hold their shape well. Green bell peppers are more earthy and slightly bitter, which can provide a nice contrast to the savory filling. For stability, look for peppers that have a flat bottom so they can sit upright in the pan without tipping over.
3. Don’t Skip the Par-Baking: Pre-baking the peppers is a critical step. It gives them a head start on cooking, ensuring the final texture is tender-crisp and not raw or crunchy. It also helps release some of their natural water content, preventing the final dish from becoming soggy.
4. Make it Your Own with Veggie Add-ins: This recipe is incredibly versatile. Feel free to bulk up the filling with other finely diced vegetables. Sautéed mushrooms, zucchini, or spinach are excellent additions. Just cook them along with the onions until they have released their moisture and softened before proceeding with the recipe.
5. Use a Muffin Tin for Stability: If your pepper halves are prone to tipping over in your baking dish, a standard-size muffin tin can be your best friend! Simply place each pepper half into a muffin cup. This will hold them upright perfectly, ensuring the filling stays put and the cheese melts evenly over the top.

Frequently Asked Questions (FAQ)

1. Do I have to cook the peppers before stuffing them?
Yes, we highly recommend it. The 15-20 minute pre-bake (or par-baking) is key to achieving the perfect texture. If you stuff raw peppers, the filling will be perfectly cooked long before the pepper itself is tender, resulting in a crunchy, undercooked shell. Par-baking ensures the pepper is soft, sweet, and fully cooked at the same time as the filling.

2. How do I make this recipe vegan?
This recipe is very easy to make vegan! There are only two ingredients to substitute. First, ensure you cook your quinoa in vegetable broth or water, not chicken broth. Second, simply omit the shredded dairy cheese or replace it with your favorite brand of dairy-free shredded cheese. To add a cheesy, savory flavor without using a cheese substitute, you can sprinkle the finished peppers with 2-3 tablespoons of nutritional yeast before the final bake.

3. What’s the best way to prevent my stuffed peppers from getting watery?
Watery stuffed peppers are usually caused by excess moisture from the peppers themselves or the filling. This recipe is designed to minimize that issue in a few ways. First, par-baking the peppers helps them release some water initially. Second, using canned diced tomatoes and draining the black beans and corn well prevents the filling from being too wet. Finally, be sure to cook down the filling mixture for about 5 minutes as directed, which allows some of the liquid from the tomatoes to evaporate and the flavors to concentrate.

4. Can I make these stuffed peppers ahead of time for meal prep?
Absolutely! This recipe is fantastic for meal prep. You have two main options:

• Option 1 (Prep Ahead, Bake Later): You can prepare the entire filling and stuff the raw pepper halves. Store the stuffed peppers in an airtight container in the refrigerator for up to 2 days. When you’re ready to eat, place them in a baking dish with water at the bottom and bake as directed, adding about 10-15 extra minutes to the initial covered baking time since you’ll be starting with cold peppers.
• Option 2 (Cook Completely): You can fully bake the peppers as directed, let them cool completely, and then store them in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or in a 350°F (175°C) oven until warmed through.

5. Are these stuffed peppers healthy?
Yes, they are an incredibly healthy and well-balanced meal. Each serving is loaded with plant-based protein from the quinoa and black beans, which are also excellent sources of dietary fiber. The bell peppers provide a rich source of Vitamin C and antioxidants. The entire dish is packed with vegetables and savory spices rather than excess fat or sodium, making it a nutrient-dense choice that will keep you feeling full and satisfied.
