Ingredients and Preparation

For the filling:

• 2 tablespoons olive oil (or avocado oil)
• 1 medium yellow onion, diced
• 3 garlic cloves, minced
• 1 pound lean ground beef (90% lean or leaner)
• 1½ cups cooked brown rice (substitute quinoa or cauliflower rice, if preferred)
• 1 tablespoon tomato paste
• 14.5 oz canned diced tomatoes (with juices)
• 1 teaspoon dried oregano
• 2 teaspoons paprika (sweet or smoked)
• Salt, to taste
• Ground black pepper, to taste

For the peppers:

• 6–7 large bell peppers (any color), tops sliced off, seeds and membranes removed
• 1 tablespoon olive oil (for brushing)
• 1 cup shredded cheddar cheese (or your choice of melting cheese)
• Optional: chopped parsley, for garnish

Preparation Notes:

• Use freshly cooked or leftover brown rice.
• Choose firm, large bell peppers that can stand upright in a baking dish.
• Shred the cheese fresh if possible for best melt quality.

Step-by-Step Instructions

Step 1: Prepare the bell peppers

• Preheat the oven to 375°F (190°C).
• Cut off the tops of the bell peppers and remove the seeds and inner membranes.
• Lightly brush the outside of each pepper with olive oil.
• Arrange them upright in a large baking dish. If needed, trim a sliver off the bottom to help them stand flat.
• Optional: Pre-bake empty peppers for 10 minutes to soften slightly (especially helpful if you like them very tender).

Step 2: Make the beef filling

• Heat 2 tablespoons of olive oil in a large skillet over medium heat.
• Add the diced onions and cook until soft and translucent, about 4–5 minutes.
• Stir in the garlic and cook for another 30 seconds until fragrant.
• Add the ground beef and cook, breaking it up with a wooden spoon, until browned and no longer pink—about 6–8 minutes.
• Drain excess fat if necessary.

Step 3: Add seasonings and rice

• Stir the tomato paste into the cooked beef mixture and mix well.
• Add the canned diced tomatoes with their juice, paprika, oregano, salt, and pepper.
• Reduce heat to low and simmer for 5 minutes to blend flavors.
• Fold in the cooked brown rice until everything is evenly combined.
• Taste and adjust seasoning if needed.

Step 4: Stuff the peppers

• Using a large spoon, fill each bell pepper generously with the beef and rice mixture.
• Press down gently to compact the filling and top each pepper with shredded cheddar cheese.

Step 5: Bake

• Pour about ½ cup water or broth into the bottom of the baking dish to create steam (optional but helps soften the peppers).
• Cover the dish tightly with foil and bake for 25 minutes.
• Remove the foil and continue baking uncovered for another 10 minutes, or until cheese is melted and peppers are tender.

Step 6: Serve

• Let the peppers cool for 5 minutes before serving.
• Garnish with chopped parsley if desired.
• Serve warm with your choice of side.

Beginner Tips and Notes

• Choose the right peppers: Red, yellow, and orange bell peppers are sweeter and roast better than green. Mix for a colorful presentation.
• Precook the rice: Have your rice ready before starting the filling. You can also use microwave rice for convenience.
• Season generously: The filling should taste good before it goes into the peppers. Adjust salt and spices to your liking.
• No overbaking: If your peppers are too soft, they may collapse. For firm yet tender peppers, avoid baking longer than 35 minutes total.
• Make ahead: You can prepare the filling and stuff the peppers a day ahead. Just cover and refrigerate, then bake when ready.
• Freezer-friendly: Cool baked peppers completely, wrap tightly, and freeze. Reheat covered at 350°F for 20–25 minutes or microwave until hot.
