These tender, flavorful stuffed bell peppers are a hands-off weeknight dinner that practically cooks itself. The slow cooker keeps the peppers perfectly tender while the beef, rice, and tomato filling melds into a comforting, savory meal that's both hearty and nutritious.

For Serving
1.5cupsshredded mozzarella cheese170g, or use cheddar
fresh parsleychopped, for garnish
Instructions
In a large skillet over medium-high heat, brown the ground beef with the diced onion and minced garlic until the meat is no longer pink, about 7-8 minutes. Drain excess fat.
In a large mixing bowl, combine the cooked beef mixture, uncooked rice, diced tomatoes with their juice, Italian seasoning, salt, pepper, and paprika. Mix well.
Cut the tops off the bell peppers and remove all seeds and membranes. Stuff each pepper firmly with the beef and rice mixture.
Pour the tomato sauce and beef broth into the bottom of your slow cooker. Carefully place the stuffed peppers upright in the liquid.
Cover and cook on LOW for 4 hours, or until the peppers are tender and the rice is fully cooked.
About 10 minutes before serving, sprinkle the shredded cheese over the tops of the peppers, cover, and let melt. Garnish with fresh parsley before serving.
Notes
For easier prep, use pre-cooked rice and reduce cooking time to 3 hours on LOW.
Choose peppers that can stand upright on their own - trim the bottoms slightly if needed, but don't cut through.
Any color bell pepper works well. Red and yellow are sweeter, while green have a more vegetal flavor.
Ground turkey or ground chicken can substitute for beef for a leaner option.
Leftover stuffed peppers store well in the refrigerator for up to 4 days in an airtight container.
To freeze, cool completely and wrap individually in plastic wrap, then foil. Freeze up to 3 months.
For a spicier version, add 1/2 teaspoon cayenne pepper or use pepper jack cheese instead of mozzarella.
The liquid at the bottom makes a great sauce - spoon it over the peppers when serving.
If your slow cooker runs hot, check peppers at 3.5 hours to avoid overcooking.
For Mexican-style peppers, swap Italian seasoning for cumin and chili powder, and use pepper jack cheese.
