Slow Cooker Stuffed Peppers (Family Favorite!)
There’s nothing like the aroma of savory, slow-cooked stuffed peppers filling the kitchen on a chilly evening. These Slow Cooker Stuffed Peppers are easy to assemble, deeply flavorful, and incredibly satisfying—making them the perfect weeknight dinner or Sunday meal prep star.
Each green pepper is packed with a hearty filling of lean ground beef, tender white rice, herbs, and aromatics, then simmered in rich tomato sauce until melt-in-your-mouth tender.
Why I Love This Recipe
This recipe is pure nostalgic comfort—with zero oven babysitting required. I love how the slow cooker does all the work, transforming basic pantry ingredients into a delicious, nourishing meal with minimal effort. You can prep the filling the night before, pop them in the slow cooker in the morning, and come home to dinner already done.
Even better? These peppers reheat like a dream, making them perfect for leftovers or freezing for another day.
Ingredients
- 1 lb. lean ground beef, cooked
- 5 large green bell peppers, tops removed and seeds cleaned out
- 1 ½ cups cooked white rice
- 1 (24 oz.) jar tomato sauce
- 2 cloves garlic, minced
- 1 medium white onion, finely diced
- ½ tsp sea salt
- ½ tsp garlic powder
- ½ tsp dried oregano
- ½ tsp dried thyme
Optional Add-ins & Swaps
- Cheese it up: Top with shredded mozzarella or parmesan during the last 30 minutes of cooking.
- Go veggie: Use lentils or black beans in place of beef for a vegetarian twist.
- Color pop: Use red, yellow, or orange peppers for sweetness and variety.
- Grain swap: Try quinoa or brown rice instead of white rice.
Step-by-Step Instructions
1. Prepare the Peppers
Cut the tops off the bell peppers and remove seeds and membranes. Be careful not to puncture the sides.
2. Mix the Filling
In a large bowl, combine cooked ground beef, cooked white rice, minced garlic, diced onion, 1 cup of tomato sauce, and seasonings (salt, garlic powder, oregano, thyme). Mix well until fully combined.
3. Stuff the Peppers
Fill each pepper with the beef and rice mixture, pressing down gently to pack the filling.
4. Slow Cook
Place the stuffed peppers upright in the slow cooker. Pour the remaining tomato sauce around the peppers and drizzle a spoonful over the tops of each one. Cover and cook on LOW for 4–5 hours, until the peppers are soft and the filling is heated through.
5. Serve and Enjoy
Carefully remove peppers using tongs or a slotted spoon. Spoon some sauce from the bottom of the slow cooker over the top and serve hot.
Tips for Success
- Don’t overstuff: Leave a little room at the top of each pepper for expansion.
- Precook the meat: This ensures even texture and flavor in the filling.
- Stand them up: Use crumpled foil or slice off a tiny bit from the pepper bottoms to help them stand upright.
- Double the batch: These freeze and reheat beautifully—perfect for meal prep!
