Ingredients
- 4 large bell peppers (various colors)
- 1 pound ground beef (lean)
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 (14.5 ounce) can diced tomatoes, undrained
- 1 (15 ounce) can tomato sauce
- 1 cup cooked rice (brown or white)
- 1/2 cup cooked quinoa (optional)
- 1 cup cooked black beans, rinsed and drained
- 1 cup shredded cheddar cheese (or mozzarella)
- 1/4 cup chopped fresh parsley
- 1 teaspoon chili powder
- 1/2 teaspoon cumin

Step-by-Step
1. Preheat oven to 375°F (190°C).

2. Prepare the bell peppers: Cut off the tops of the peppers and remove the seeds and membranes.
3. Blanch the peppers: Place the peppers in a pot of boiling water for 5 minutes to soften them slightly. This helps them cook evenly in the oven. Remove and drain.
4. Cook the ground beef: In a large skillet, brown the ground beef over medium-high heat. Drain off any excess grease.
5. Sauté aromatics: Add the chopped onion and minced garlic to the skillet with the ground beef. Cook until the onion is softened, about 5 minutes.
6. Combine the ingredients: Stir in the diced tomatoes (undrained), tomato sauce, cooked rice, cooked quinoa (if using), cooked black beans, chili powder, cumin, smoked paprika, salt, and pepper.
7. Simmer the mixture: Bring the mixture to a simmer and cook for 5-7 minutes, allowing the flavors to meld together.
8. Stuff the peppers: Spoon the ground beef mixture into the prepared bell peppers, filling them to the top.
9. Top with cheese: Sprinkle the shredded cheddar cheese (or mozzarella) over the stuffed peppers.
10. Bake the peppers: Place the stuffed peppers in a baking dish and bake for 30-40 minutes, or until the peppers are tender and the cheese is melted and bubbly.
11. Garnish and serve: Garnish with chopped fresh parsley before serving.
Variations and Substitutions
Exploring Different Protein Sources
While ground beef is the star of this recipe, there are several ways to adapt it to your dietary preferences.
Consider ground turkey or chicken as leaner alternatives.
For a vegetarian option, use plant-based ground meat substitutes.
You could also add cooked lentils or crumbled tofu for extra protein and fiber.
Flavor Enhancements and Ingredient Swaps
Don’t be afraid to experiment with different flavor profiles.
Swap cheddar cheese for Monterey Jack, pepper jack, or even a sprinkle of feta.
Add a can of drained and rinsed corn for sweetness and texture.
Spice things up with a pinch of red pepper flakes or a dash of your favorite hot sauce.
For a richer flavor, use fire-roasted tomatoes instead of regular diced tomatoes.
Adjusting Carb Content and Dietary Needs
If you’re watching your carb intake, consider using cauliflower rice instead of regular rice.
You can also omit the rice and beans altogether and increase the amount of ground beef and vegetables.
For a gluten-free version, ensure all your ingredients, especially the tomato sauce, are gluten-free.
Tips for Perfect Stuffed Peppers
Choosing the Right Peppers
Select peppers that are firm, brightly colored, and free from blemishes.
Bell peppers come in a variety of colors, each with a slightly different flavor profile.
Green peppers are the most common and have a slightly bitter taste.
Red, yellow, and orange peppers are sweeter and milder.
Choose peppers that are roughly the same size so they cook evenly.
Preparing the Peppers Properly
Blanching the peppers before stuffing them helps to soften them and reduces their cooking time.
Be careful not to overcook them during the blanching process, as they will continue to cook in the oven.
Make sure to remove all the seeds and membranes from the peppers to avoid a bitter taste.
Baking and Serving
Use a baking dish that is just large enough to hold the peppers snugly.
This will help them retain their shape and prevent them from tipping over.
Cover the baking dish with aluminum foil for the first half of the baking time to prevent the cheese from browning too quickly.
Let the peppers rest for a few minutes before serving to allow the filling to set.

Make-Ahead and Storage Instructions
Preparing Ahead of Time
You can prepare the ground beef filling up to 2 days in advance.

Reheating Tips
Reheat leftover stuffed peppers in the oven for best results.
