FAQs
Can I use uncooked rice in this recipe?
It’s best to use cooked rice because uncooked rice won’t have enough time to fully cook in the slow cooker without overcooking the peppers.
What if my peppers fall over during cooking?
It’s common for stuffed peppers to tip over as they cook. They will still cook evenly and taste great, so no need to worry if they aren’t perfectly upright.

Ingredients
Filling
- 1 lb. ground beef
- 1 ½ cups cooked rice (can be leftover rice)
- 1 small white onion, diced
- ½ tsp. salt
- ¼ tsp. garlic powder
- ½ tsp. dried thyme
- ½ tsp. dried oregano (tarragon works well too)
- 5 bell peppers (tops cut off and diced for filling)
- 24 oz. jar marinara sauce, divided
Instructions
- Brown ground beef: Place the ground beef in a skillet over medium heat on the stovetop. Cook until browned, breaking it apart with a spoon. Once browned, drain excess fat and set aside.
- Prepare filling: In a medium bowl, combine the browned beef, diced bell pepper tops, cooked rice, 1 cup of marinara sauce, diced onion, salt, garlic powder, dried thyme, and oregano. Stir well to incorporate all ingredients evenly.
- Stuff peppers: Take each hollowed bell pepper and fill them generously with the beef and rice mixture. If any filling remains, place it at the bottom of the slow cooker to prevent sticking and to add flavor.
- Add marinara sauce: Pour the remaining marinara sauce into the bottom of the slow cooker around the peppers to keep them moist and enhance the taste.
- Arrange in slow cooker: Place the stuffed peppers upright inside the slow cooker, trying not to let them touch the sides to maintain their shape; however, they may fall over during cooking, which is normal.
- Cook low and slow: Cover the slow cooker with its lid and cook on the LOW setting for 5 hours. Avoid opening the lid during cooking to ensure steady heat and proper cooking.
Notes
- You can use any color bell peppers for this recipe, but red, yellow, and orange add sweetness.
- Leftover cooked rice works great here for convenience.
- If you prefer a spicier flavor, add red pepper flakes or chopped jalapeños to the filling.
- For a lower-fat version, substitute ground beef with ground turkey or chicken.
- Do not open the slow cooker lid during the 5-hour cooking period to maintain heat and cook evenly.
