  7. Sprinkle shredded mozzarella cheese evenly over the top of each stuffed pepper.
  8. Arrange the stuffed peppers in a baking dish or on a baking sheet.
  9. Bake for about 35 minutes until the peppers are tender and the cheese is melted and lightly golden.
  10. Remove from the oven and allow them to cool slightly before serving.

Notes

  • Add vegetables like zucchini, spinach, or corn to the filling for extra nutrition and color.
  • Swap brown rice with quinoa, white rice, or cauliflower rice for a different texture.
  • Use cheeses such as Monterey Jack, cheddar, or Italian blends for varied flavor.
  • Add crushed red pepper flakes or diced jalapeños for a spicier version.
  • Mix in cooked lentils or chickpeas for extra protein.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
  • Reheat in the microwave for 1–2 minutes or in a 350°F (175°C) oven for about 15 minutes.
  • Freeze individually wrapped peppers for up to 2 months and thaw overnight before reheating.
