These Slow Cooker Stuffed Peppers feature seasoned beef and rice tucked inside tender peppers, all simmered in a rich sauce, and my recipe sticks to nostalgic, pantry-friendly ingredients you already love.
Recipe Highlights
Built-in portions: one pepper = one tidy serving, perfect for dividing up
Edible vessel: the pepper itself becomes a tender, flavorful bowl that you can cut up and eat as you go
A Complete meal: my crockpot stuffed peppers are a full meal – Meat, veggies and starch
Key Ingredients
- Bell peppers – Green Bell Peppers are classic for this. If your bell peppers are very large you may need to use less than five.
- Ground beef – The meat is browned and crumbled.
- Rice – Leftover cooked rice works well in this stuffed peppers recipe.
- Onion – Diced white onion adds flavor and heartiness to the crock pot stuffed peppers.
- Marinara – I choose to use marinara instead of tomato sauce or diced tomatoes; you can use homemade marinara sauce if desired.
- Seasonings – Salt, pepper, thyme and oregano are all you need!
How to Make Slow Cooker Stuffed Bell Peppers
- Combine browned beef with diced pepper tops, rice, seasonings, and a splash of marinara.
- Stuff the peppers, pour remaining sauce around them in the crockpot.
- Cover and cook on low until the peppers collapse into tender, saucy goodness.
Variations
Here are my ideas for changing up this recipe:
- If you’re going for a veggie option, swap the beef for soy crumbles or a can of pinto beans. You can also toss in extra veggies like chopped squash or asparagus to the rice mix.
- Salsa works great as a replacement for marinara sauce, and you can use Italian seasoning instead of thyme and oregano for a different flavor.
- Prefer something other than ground beef? Try ground chicken, turkey, pork, or Italian sausage instead.
How to Serve Beef and Rice Stuffed Peppers
These peppers are very filling, so you don’t need many sides:
- These can certainly be considered a full meal in one pepper, but you can serve with a green salad and garlic bread!
- Stuffed peppers often come with cheese, but it’s totally optional. If you want some cheesy goodness, sprinkle about 2 tablespoons of shredded mozzarella on each pepper about 10 minutes before they’re done cooking.
- When it comes to other toppings, you can try a variety of ideas such as a dollop of sour cream, diced tomatoes, salsa, or bacon bits.

I make this often and it always turns out great! I especially like it for the summer because it doesn’t heat up the house. Thanks for sharing!

How to Video
Ingredients
- 1 lb. ground beef
- 5 bell peppers, tops cut off and diced for filling
- 1 ½ cups cooked rice, can be leftover rice
- 24 oz. jar marinara sauce, divided
- 1 small white onion diced
- ½ tsp. salt
- ¼ tsp. garlic powder
- ½ tsp. dried thyme
- ½ tsp. dried oregano, tarragon works well too
Instructions
- Brown the ground beef in a skillet on the stove top. Drain.
- Add the beef, cut up bell pepper tops, rice, 1 cup of the marinara sauce, onion, salt, garlic powder, thyme and oregano to a medium sized bowl. Stir.
- Stuff the peppers with the filling you just made. If there is any leftover filling add it to the bottom of the slow cooker.
- Add remaining marinara sauce to the slow cooker.
- Add the stuffed peppers in the slow cooker. I try not to let them rest on the sides of the slow cooker, but most of the time they end up falling over later.
- Cover and cook on LOW for 5 hours without opening the lid during the cooking time.

What can be used instead of rice? Than ks!
You can leave the rice out completely, or you can add corn or black beans.
I’ve made this recipe twice now, once with ground beef and once with ground venison. I used parboiled rice instead of fully cooked rice, however and added fresh oregano from the garden. Otherwise followed exactly. I would suggest adding more herbs and spices when using venison. This recipe was a lifesaver, as my oven unexpectedly quit working. I had never used a crock pot for stuffed peppers and was skeptical. I will never again make them any other way! Thank you!
That is great to hear! Glad to know it works with venison.
Delicious recipe. I used close to two pounds of ground beef, 1.5 cups of leftover cold white rice (precooked). Instead of tomatoes I used Lipton tomato soup , I mixed it in with the beef mixture .
So good . I spread more tomato soup on top.
I love idea of chopping tops of peppers w diced onion to add to mix (I did saute these n season as per recipe) it was excellent.
One problem , 5 hours is too long even on low.
The peppers were little overcooked and kind of falling apart, other than this it was perfect.
Can I freeze any leftovers?
Making these now and I can’t wait to taste them!

Sarah, we live in Canada and use at least one of your slow cooker recipes a week…delicious…what kind of beef (lean or medium) should I use..and can I stuff them with raw beef and uncooked rice?..do you think it will be greasy if I do it this way..thank you and you are the best!
You can stuff them with raw meat (lean) but it will turn out more like meatloaf. – Shouldn’t be greasy.
Last question…would I still use a cup and a half of uncooked rice? And one pound of raw lean ground beef? Thank you for your patience…
there’s and unwritten rule with white rice I use. its a 3 times rule. So if I want 3cups of rice I use 1cup raw and same with the water use 3 cups in this example. So if I were to end up with 1.5 cups cooked rice I would divide 3 and use half a cup of raw white rice. it’ll end up being the 1.5 cups in the end. Just saying what I’d do this recipe. I agree I’m going to try the raw lean ground beef and raw rice too.
Followed your directions and the rice turned into mush. It was so bad we threw it in the trash, horrible !
Does raw meat and uncooked rice lengthen the time or still 5 hours?
It will still be about 5 hours.
Thank you!
