Ingredients

Yield: 6 stuffed peppers · Serving size: 1 stuffed pepper · Baking dish: 9-by-13-inch

• 6 medium bell peppers (red, yellow, or orange)
• 1 pound lean ground beef (90% lean)
• 1 can (15 ounces) black beans, drained and rinsed
• 1 can (10 ounces) Rotel diced tomatoes with green chilies, undrained
• 1 cup cooked quinoa
• ½ cup corn kernels, fresh or frozen
• 1 small onion, diced
• 2 garlic cloves, minced
• 1 tablespoon olive oil
• 2 teaspoons chili powder
• 1 teaspoon ground cumin
• ½ teaspoon smoked paprika
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ¾ cup shredded Mexican-blend cheese
• Optional: fresh cilantro, lime wedges, or plain Greek yogurt

Instructions

1. Preheat the oven. Heat the oven to 375°F. Lightly grease a 9-by-13-inch baking dish.
2. Prepare the peppers. Slice the tops off the bell peppers and remove the seeds and membranes. Arrange the peppers upright in the baking dish. Add ¼ cup water to the bottom of the dish, cover with foil, and bake for 15 minutes while preparing the filling.
3. Brown the beef. Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook for approximately 3 minutes, until it begins to soften. Add the ground beef and cook for 6–8 minutes, breaking it into crumbles until browned and cooked through. Drain excess fat if necessary.
4. Add the seasonings. Stir in the minced garlic, chili powder, cumin, smoked paprika, salt, and black pepper. Cook for approximately 1 minute, stirring gently, until the garlic and spices become fragrant.
5. Prepare the filling. Add the drained black beans, Rotel with its juices, cooked quinoa, and corn. Stir until the ingredients are evenly combined. Simmer for 3–5 minutes, allowing the flavors to blend and the mixture to thicken slightly.
6. Stuff the peppers. Carefully remove the peppers from the oven and drain any water that has accumulated inside them. Spoon the beef and bean mixture evenly into all six peppers. Sprinkle the shredded Mexican-blend cheese over the tops.
7. Bake and serve. Cover loosely with foil and bake for 15 minutes. Remove the foil and bake for another 5–10 minutes, until the peppers are tender, the filling is hot, and the cheese is melted. Garnish with fresh cilantro or serve with lime wedges and plain Greek yogurt if desired.

Estimated Nutrition Per Serving

Estimated nutrition per stuffed pepper, based on six servings using 90% lean ground beef and standard canned ingredients. Actual values depend on pepper size, cheese brand, the amount of beef fat drained, and serving sizes. Added sugar is approximately zero when the canned tomatoes, beans, and other ingredients contain no added sugar. Optional toppings are not included.

Why This Recipe Is a Healthy Choice

Lean ground beef provides complete protein along with important nutrients such as iron, zinc, and vitamin B12. Protein supports muscle maintenance and repair, which becomes especially important as we age. Black beans contribute additional plant-based protein, making this a substantial meal with approximately 27 grams of protein per serving.

Black beans and quinoa are also valuable sources of dietary fiber. Fiber supports digestive health, promotes fullness, and can help make meals more satisfying. Quinoa adds complex carbohydrates, magnesium, and other nutrients, while the combination of beans, vegetables, and quinoa provides approximately 8 grams of fiber per serving.

Bell peppers bring even more nutritional value to the meal. Red, yellow, and orange peppers are excellent sources of vitamin C and provide colorful plant pigments, including carotenoids. The tomatoes, corn, onions, and garlic contribute additional nutrients and naturally occurring plant compounds. Using the pepper itself as the container is also a delicious way to build more vegetables into dinner.

The homemade Southwestern seasoning blend is another highlight. Chili powder typically contains a mixture of ground chili peppers and aromatic spices, while cumin contributes its distinctive earthy, warm flavor. Smoked paprika adds depth and smokiness, and garlic provides a savory foundation. These ingredients contain naturally occurring plant compounds, including polyphenols and, in paprika and chili peppers, carotenoid pigments.

Although seasonings are used in relatively small amounts, combining them creatively can make a tremendous difference in how enjoyable a meal becomes. Preparing your own seasoning blend also gives you greater control over the amount of salt and other ingredients, rather than relying on a packaged taco or chili seasoning mix.

Olive oil contributes unsaturated fats, while the cheese adds satisfying richness, calcium, and additional protein. The finished recipe is a wonderful example of the LifesYearning Complete in 3 approach: protein from beef and beans, fiber from beans, quinoa, and vegetables, and satisfying fats from olive oil, beef, and cheese. Everything comes together in one flavorful meal.

Mary’s Opinion – Taste Test

Another winner! These Southwest Beef & Black Bean Stuffed Peppers were absolutely delicious and are definitely going into my regular meal rotation. I’ve always enjoyed stuffed peppers, but the combination of Southwestern spices, black beans, corn, and seasoned ground beef makes these especially tasty. There’s so much wonderful flavor packed into one pepper!

One thing I particularly liked was using quinoa instead of rice. Sometimes I think rice can take over a stuffed pepper, but the quinoa has a lighter texture that blends beautifully with the other ingredients. It also provides more protein and fiber than traditional white rice, which is a nice nutritional bonus.

And speaking of nutrition, this is exactly the kind of Complete in 3 meal I love! With approximately 27 grams of protein and 8 grams of fiber per serving, we’re getting a substantial amount of both in one delicious dish. Add in the satisfying fats from the beef, olive oil, and cheese, and there’s no need to prepare several different dishes to put together a balanced meal.

I also love how easy these are to prepare. The chili powder, cumin, smoked paprika, and garlic give the filling such a bold Southwestern flavor, while the sweet bell peppers provide a delicious contrast. It’s a wonderful reminder that combining the right herbs and spices can turn familiar ingredients into something special.

These stuffed peppers are flavorful, nutritious, filling, and easy to make. Everything I’m looking for in a recipe! I’ll definitely be making these again. Another keeper!

Cooking Notes

Choose colorful bell peppers: Red, yellow, and orange peppers are naturally sweeter than green peppers and complement the savory Southwestern filling beautifully. Look for peppers with relatively flat bottoms so they stand upright in the baking dish.

Pre-bake the peppers: Giving the peppers a 15-minute head start helps soften them before adding the filling. This prevents the beef and bean mixture from becoming overcooked while waiting for the peppers to become tender.

Use cooked quinoa: The recipe calls for 1 cup of already cooked quinoa, not dry quinoa. Quinoa can be prepared ahead of time or made from leftovers. Rinse dry quinoa before cooking if the package doesn’t indicate it has already been rinsed.

Drain and rinse the black beans: Rinsing canned beans removes some of the sodium and the thick canning liquid. Black beans add a hearty texture, protein, and fiber without requiring much preparation.

Choose the right Rotel: Rotel diced tomatoes with green chilies add a pleasant Southwestern flavor and some heat. Choose mild, original, or hot depending on your preference. The canned tomatoes should be added with their juices to help keep the filling moist.

Make your own Southwestern seasoning blend: Chili powder, cumin, smoked paprika, and garlic work together to create a bold, warm flavor. The cumin adds earthiness, paprika contributes smokiness, and chili powder supplies the familiar Southwestern character. Adjust the proportions to suit your taste without relying on a packaged seasoning mix.

Adjust the heat: If you enjoy spicy food, add a pinch of cayenne pepper or crushed red pepper flakes. For a milder version, use mild Rotel and a gentle chili powder blend.

Don’t make the filling too wet: Allow the beef, beans, quinoa, tomatoes, and corn to simmer for several minutes before stuffing the peppers. The mixture should be moist and flavorful without having excess liquid pooling in the skillet.

For softer peppers: If you prefer very tender peppers, extend the initial baking time by approximately 5 minutes before adding the filling. Cooking times may vary with the size and thickness of the bell peppers.

Make-ahead option: Prepare the beef and bean filling in advance and refrigerate it in a covered container. When ready to serve, pre-bake the peppers, fill them, and bake until tender and thoroughly heated. The filling may need extra oven time if added cold.

Storage and reheating: Refrigerate leftovers promptly in an airtight container for 3–4 days. Reheat until the center reaches 165°F. Individual stuffed peppers make convenient lunches or dinners for the following day.

Serving suggestions: These stuffed peppers are substantial enough to serve on their own. Add a spoonful of plain Greek yogurt, fresh cilantro, or a squeeze of lime for additional flavor. A simple green salad also pairs nicely with the Southwestern seasonings.
