Step-by-Step Instructions
1. Prepare the Bell Peppers
You will start by preheating your oven to 375°F (190°C). Then, carefully cut each bell pepper in half lengthwise and remove the seeds and membranes. Place the pepper halves cut-side up in a baking dish.
2. Cook the Ground Beef Filling
In a large skillet over medium heat, warm the olive oil. Add the ground beef and cook, breaking it apart with a spoon, until it’s no longer pink. Drain any excess fat.
3. Sauté Aromatics and Combine Filling Ingredients
Add the chopped onion to the skillet with the cooked beef and cook until softened, about 5 minutes. Stir in the minced garlic, oregano, basil, salt, and pepper, cooking for one more minute until fragrant. Next, stir in the diced tomatoes (undrained), cooked cauliflower rice, and 1/2 cup of shredded cheddar cheese.
4. Stuff the Peppers
Evenly divide the beef and cauliflower rice mixture among the prepared bell pepper halves. Pour the beef broth into the bottom of the baking dish around the peppers. This helps to keep them moist while baking.
5. Bake the Stuffed Bell Peppers
Cover the baking dish loosely with aluminum foil. Bake for 30 minutes, then remove the foil, sprinkle the remaining shredded cheddar cheese over the stuffed peppers, and bake for another 5-10 minutes, or until the cheese is melted and bubbly and the peppers are tender.
Variation Ideas
- Add a pinch of red pepper flakes for a little heat.
- Mix in finely diced mushrooms or zucchini to the filling for extra vegetables.
- Use a different cheese like mozzarella or Monterey Jack.
- Top with fresh chopped parsley before serving.
