There’s something so satisfying about biting into a slow cooker peppers stuffed with seasoned beef and rice, all that tender vegetable, savory filling, and melted cheese in every bite. This is the kind of dinner that feels like home cooking at its best, and the crockpot does practically all the heavy lifting for you.
I love this recipe because it’s a complete meal nestled right inside the pepper itself. You get your protein, your grain, your veggies, and that comforting tomato sauce all working together beautifully.
The best part? You’ll spend maybe ten minutes prepping, then walk away while your slow cooker transforms everything into something absolutely delicious.
The Ingredient Lineup
You probably have most of these staples in your pantry already. The beauty of this dish is how straightforward the ingredient list is, no fancy items or hard-to-find things, just honest comfort-food flavors.
- Bell peppers (6): Pick any color you like, red, yellow, orange, or green all work wonderfully. Mix colors if you want a prettier presentation on the table.
- Ground beef (1 lb): Lean ground beef keeps things from getting too greasy, but regular ground beef works fine too if that’s what you have.
- Cooked rice (1 cup): Use leftover rice from yesterday’s dinner, or cook some fresh rice ahead of time. The rice needs to be cooked already since the slow cooker won’t cook dry rice through properly.
- Cheddar cheese (2 cups): I use half in the filling and half on top for that gorgeous melted finish. Sharp cheddar has more flavor if you prefer that.
Making Slow Cooker Peppers Stuffed with Ground Beef and Rice, Step by Step
Here’s how to turn six simple peppers into a weeknight dinner that tastes like you’ve been cooking all day.
Step 1: Prepare Your Peppers
Slice the top off each pepper and scoop out all the seeds and white ribs inside. If you have usable pepper from the tops, chop it up finely, it’ll go right into your filling. If your peppers are wobbly, trim a thin slice off the bottom so they sit flat in the slow cooker.
Step 2: Make the Filling
In a bowl, combine the ground beef, cooked rice, crushed tomatoes, one cup of cheese, onion powder, garlic powder, Italian seasoning, salt, black pepper, and Worcestershire sauce. Mix everything together really well so the seasonings are evenly distributed. Stir in any chopped pepper pieces you saved from the tops.
Step 3: Layer the Slow Cooker
Pour the tomato sauce into the bottom of your slow cooker, this creates a delicious base and keeps everything moist. Arrange the peppers upright in the cooker and stuff each one generously with the beef mixture. If you have any extra filling left over, spoon it on top of the peppers or into the sauce around them.
Step 4: Cook Low and Slow
Cover and cook on high for 4 hours or on low for 6 hours. The peppers should be tender and the beef cooked through when done. You don’t need to peek or stir, just let the slow cooker work its magic.
Step 5: Add the Cheese Topping
About 15 minutes before serving, sprinkle the remaining cup of cheese over each pepper. Cover again and let it melt into that bubbly, golden layer everyone loves. Spoon some of that rich tomato sauce from the bottom of the cooker over everything when you serve.
Serving Suggestions
- Serve with a simple green salad and crusty bread to soak up that delicious tomato sauce.
- Pair with roasted broccoli or steamed green beans for a complete veggie-forward meal.
- Add a dollop of sour cream or Greek yogurt on top for a cool, tangy contrast.
- Sprinkle with fresh parsley or chives right before serving for a pop of color and freshness.

Pro Tips for Success
- If you don’t have cooked rice on hand, cook some while you’re prepping the peppers, it’ll be ready by the time you need it.
- Don’t skip chopping up the usable pepper from the tops; it adds extra flavor and texture to your filling.
- For extra cheesy peppers, use a full 2.5 cups of cheddar and divide it three ways instead of two.
- These peppers hold their shape beautifully, so they’re great for plating and look impressive on the dinner table.
- If your peppers are very large, you might need to cook them an extra 30 minutes on low to get them perfectly tender.
Make-Ahead, Storage & Leftovers
Store
Keep leftovers in an airtight container in the refrigerator for up to 4 days. The peppers actually taste even better the next day as the flavors meld together.
Freeze
You can freeze cooked stuffed peppers in a freezer-safe container for up to 3 months. Freeze them in a single layer first, then stack them once solid.
Reheat
Thaw overnight in the fridge, then warm gently in a 350°F oven covered with foil for about 20 minutes, or reheat individual peppers in the microwave.

Substitutions That Work
- Brown rice or cauliflower rice work in place of white rice if you prefer those options.
- Swap the cheddar for mozzarella, Monterey Jack, or any melting cheese you have on hand.
- Use marinara sauce or pasta sauce instead of tomato sauce if that’s easier for you.
- Italian herbs or a homemade seasoning blend can replace the pre-mixed Italian seasoning.
Tasty Variations
- Use ground turkey or ground chicken instead of beef for a lighter version that cooks just the same.
- Add diced jalapeños, bell pepper pieces, or diced onion directly into the filling for more texture and flavor.
- Top with a sprinkle of fresh parsley or a dash of hot sauce before serving for a fresh or spicy twist.

- Slice the tops off of the bell peppers and scoop out the ribs and seeds from the inside. If peppers don't sit flat, slice off a small part of the bottom to create a flat surface. Finely chop any usable portion of the tops and bottom to use in the meat mixture.
- In a bowl, combine the ground beef, rice, crushed tomatoes, half of the cheese, onion powder, garlic powder, Italian seasoning, salt, pepper, and Worcestershire sauce. Add any chopped bell pepper from the tops. Mix together thoroughly.
- Pour tomato sauce into the bottom of the slow cooker.
- Stuff meat mixture tightly into bell peppers and place in slow cooker. Spoon extra meat mixture on top if you have any.
- Cover and cook until meat has cooked through and peppers are soft, 4 hours on high or 6 hours on low.
- Before cooking time ends, top peppers with remaining cheese and recover until cheese melts, about 15 minutes. Serve with sauce spooned over the peppers. Enjoy!
