Easy stuffed bell peppers filled with seasoned ground beef, rice, diced veggies, and melted cheese. Perfect for a hearty, comforting dinner that’s simple to make.
Preheat oven to 400 degrees Fahrenheit. Wash and dry the outside of the bell peppers.
Cook the rice according to package instructions and set aside.
Carefully cut the tops off each bell pepper, remove the seeds and membranes, and dice the tops. If needed, trim bottoms slightly so peppers stand upright.
In a large skillet over medium heat, heat olive oil. Add diced onion and diced bell pepper tops and cook for 5-7 minutes until softened.
Add lean ground beef and minced garlic to skillet. Cook, stirring often and breaking up meat, until fully browned.
Drain excess fat if needed, then reduce heat to medium. Stir in diced tomatoes and cooked rice.
Season mixture with kosher salt, black pepper, oregano, and red pepper flakes. Simmer on low for 5 minutes, then remove from heat.
Evenly fill each bell pepper with the beef mixture. Sprinkle about 2 teaspoons Parmesan cheese over the filling in each pepper.
Top peppers with 1.5 tablespoons mozzarella cheese each, enough to lightly cover but still show filling.
Pour 0.5 cup water into the baking dish. Cover dish tightly with foil sprayed with cooking spray. Bake at 400 degrees for 35 minutes.
Remove foil and bake uncovered an additional 10 minutes until cheese is melted and slightly browned. Serve hot.
Notes
For a twist, try using ground turkey instead of beef and add your favorite herbs. Leftover stuffed peppers reheat well and make great next-day meals.
