Slow cooker stuffed bell peppers are one of those dinners that feels like a warm hug at the end of a long day. Colorful peppers packed with seasoned ground beef, wild rice, and melty cheese, all slow cooked to tender perfection. I make this on busy weeknights when I want a wholesome meal without spending hours in the kitchen.
The first time I made this, I was skeptical a crockpot could do the job right. I was wrong. The peppers come out soft and flavorful, the filling stays juicy, and the cheese melts into every bite. These slow cooker stuffed bell peppers have become a regular in my weekly dinner rotation, and I think they will in yours too.
Ingredients for Slow Cooker Stuffed Bell Peppers
I always keep these ingredients stocked because this recipe comes together fast. I recommend picking the largest bell peppers you can find at the store since bigger peppers hold more filling and cook more evenly. A wild rice mix adds the best nutty flavor and hearty texture.
- 6 large bell peppers (any color, tops cut off, seeds and membranes removed)
- 1 lb lean ground beef (I always use 90/10 for less grease and a better texture)
- 1/2 cup yellow onion, finely chopped
- 1 (14 oz) can diced tomatoes, undrained (my go-to is fire-roasted for extra depth)
- 1 cup cooked wild rice, prepared ahead of time
- 2 tbsp Worcestershire sauce (pro tip: do not skip this, it adds incredible savory depth)
- 1 tsp salt
- 1 tsp black pepper
- 1 1/2 cups shredded Colby Jack cheese, divided (1 cup for filling, 1/2 cup for topping)
- 1/4 cup water
Step-by-Step Instructions
In my experience, the key to perfect slow cooker stuffed bell peppers is not crowding the crockpot and making sure the filling is well seasoned before the peppers go in. Take your time with the mixing step and you will be rewarded.
Step 1: Cut off the tops of the bell peppers and remove all seeds and membranes. Rinse them quickly and set aside while you prepare the filling.
Step 2: In a large mixing bowl, combine the raw ground beef, chopped onion, diced tomatoes, cooked wild rice, Worcestershire sauce, salt, pepper, and 1 cup of the shredded cheese. Mix until just combined. Do not overmix or the filling will become dense.
Step 3: Firmly stuff each bell pepper with the meat and rice mixture, pressing it down gently to fill any air pockets. Pour 1/4 cup of water into the bottom of the slow cooker. This creates steam that softens the peppers and prevents burning.
Step 4: Place the stuffed peppers upright in the slow cooker. Make sure they have a little space between them. Cook on LOW for 6 hours or HIGH for 4 hours. The peppers should be fork-tender and the beef fully cooked through with no pink remaining.
Step 5: About 15 minutes before serving, sprinkle the remaining 1/2 cup of cheese over the tops of each pepper. Replace the lid and let the cheese melt completely before serving.
What to Serve with Slow Cooker Stuffed Bell Peppers
These peppers are hearty and filling on their own, but the right side dishes turn this into a truly satisfying spread. Think about balancing the rich, savory filling with something fresh or light alongside.
Crusty Bread: Perfect for scooping up the savory juices from the bottom of the slow cooker. A simple baguette or warm dinner roll is all you need.
Simple Green Salad: A crisp salad with a light lemon vinaigrette cuts through the richness of the beef and cheese beautifully. Try pairing it with this healthy chicken salad on the side for a protein-packed lunch spread.
Slow Cooker Corn on the Cob with Garlic Herb Butter: A sweet, buttery side that complements the savory filling perfectly. You can even cook it in a second slow cooker at the same time.
Mashed Potatoes: Creamy mashed potatoes alongside these stuffed peppers make this feel like a full Sunday feast. The flavors work together wonderfully.
Crockpot Ground Beef Pasta: If you are feeding a bigger crowd, this easy pasta dish uses the same base ingredients and rounds out the table without extra effort.
Cheesy Asparagus Slow Cooker: A simple, cheesy vegetable side that cooks hands-free and pairs perfectly with the hearty bell pepper filling.
Storage and Serving Tips
Leftover slow cooker stuffed bell peppers keep well in an airtight container in the refrigerator for up to 4 days. They actually taste even better the next day as the flavors continue to develop overnight.
To reheat, warm them in the oven at 350 degrees F for 5 to 10 minutes for the best texture, or microwave for 3 to 5 minutes if you are in a rush. I recommend the oven whenever possible since it helps keep the pepper slightly firm rather than mushy.
For freezing, let the peppers cool completely, wrap each one individually in foil, and place them in a freezer-safe bag. They freeze well for up to 1 month. Thaw overnight in the refrigerator before reheating. Pro tip: these make excellent meal prep. Make a full batch on Sunday and enjoy easy weeknight dinners all week long.
FAQs
