Slow-Cooker Stuffed Pepper Soup is full of seasoned beef, rice, bell peppers and plenty of rich flavors. This first time I made this soup, I suspected it was going to be a hit with my family and I was right.
I created this soup on a cold winter night when I was craving a hearty and warming soup and Sean was craving stuffed peppers.

Spicy Italian Stuffed Bell Peppers are one of Sean’s favorite meals and for a good reason. The combination of textures and flavors in a stuffed pepper is hard to beat!
I had a hunch that those same ingredients could come together to make a tasty soup and I was right. What I didn’t expect is just how much Sean and my boys loved it.
My oldest son commented that it reminded him of the stuffed peppers and the other two kids ate every bite as well.
Stuffed Pepper Soup was an immediate favorite from the first bite and we’ve made this soup countless times over the past few years. The soup freezes beautifully and I keep individual size containers in the freezer for easy lunches.
Slow Cooker Stuffed Pepper Soup
If you make a lot of soup you might have noticed that it often tastes even better the next day once the flavors have had a chance to deepen and meld. Cooking this soup in the slow cooker means you get that delicious “second day” flavor right from the first taste.
Another reason I love slow cooker stuffed pepper soup is that you can prepare it early in the day, throw everything in the crock pot then forget about it until dinner time.
It’s a great option for both busy days and slow winter weekends when the delicious scent of cooking peppers, onions and spices will fill your home all day long.

As much as I love stuffed peppers, and as relatively easy as they are to make, this soup is even easier. You can all the taste, flavor and spice of stuffed peppers without having to actually stuff anything!
This soup uses a simple spice profile of crushed red pepper and Italian seasoning that I love with the bell peppers and black beans.
Stuffed Pepper Soup Recipe
You start by cooking ground beef on the stove with spices and onions. The beef and onion mixture is then added to the slow cooker with tomato sauce, beef stock, beans and peppers to cook. Serve with a generous helping of cooked rice added to each bowl.
You can make this entire recipe on the stove top if you prefer. Simply add the other ingredients right to the pot that you cook the beef and onions in. Cook for about an hour until the peppers are tender.
Note: I always cook the rice separately from the rest of the soup ingredients when I make this recipe. Others who’ve made this soup have said it also works by adding uncooked rice to the slow cooker or pot with the other ingredients.
If you do try it that way just keep a close eye on the soup to make sure the rice doesn’t get overcooked and dissolve into mush.

Kitchen Tip: I use this slow cooker to make this recipe.
Slow cookers or crockpots are an appliance of which I have more than one. If you are an avid slow cooker user like I am, you might understand the need for more than one. So, let’s talk about my favorites:
First up is this 6-quart slow cooker that has a locking lid. These crockpots are fantastic for transporting foods. Mine has gone everywhere from church potlucks to barbecues, game nights to Thanksgiving dinner. However, fair warning, these slow cookers run crazy hot. Low is closer to a boil than a simmer, the warm setting actually simmers. So trust me when I say HIGH is high.
My everyday slow cooker is this 8-quart Crockpot. It’s my go-to appliance for cooking large roasts and big batches of chili. Fun fact: did you know that a full 4-quart cooker, actually cooks more slowly than a half-full 8-quart cooker?
For just cooking a few pounds of chicken to shred for enchiladas or other smaller recipes, this 3-quart version is perfect.
Thanksgiving has become a breeze since I have mastered how to hold all of the side dishes using these medium-sized round slow cookers.
If you aren’t a fan of the idea of keeping more than one slow cooker in the house, these CrockPockets are a game-changer when it comes to preparing and holding multiple dishes at the same time. They slide into a standard 6-quart crockpot, dividing it into two sections that are perfect for serving different side dishes or keeping taco fillings warm for parties.
Stuffed Pepper Soup Recipe

I think you're cooking all my husbands favorites. He loves ground beef and bell peppers – I will make this for him and tell him it's from you 🙂 Thanks!
Chris says
Since I'm a FREAK for stuffed bell peppers, yeah, I "might" just like this a "bit" 🙂
Michelle Burdiss says
Do the crushed red pepper flakes make it very spicy? If so, do you think it would still be tasty without it? I’m nervous about the spice and my young ones. Thanks in advance!!
Mary Younkin says
Hi Michelle, you can leave out the red pepper flakes if you’re leery of the possible heat.
Honeyds21 says

I have made this several times and it is delicious. The last time I made enough to freeze some for when it turns colder in FL (LOL) . It gets better with age and we love it. – Annie

When you are freezing this soup, do you then add all of the cooked rice, mix it in, then freeze it in containers?? Recipe only stated how to handle the rice if eating it right away. Thanks
Rita says

cyndi says
but shredded cabbage in and leave the rice out for low carb spectacular soup! Cabbage can be added at any time depending on tenderness desired
Mary Younkin says
I’m glad you like the soup, Cyndi. I bet it was delicious with the cabbage.
Beth says
I love to start a meal in the morning in the crackpot! This was perfect for a wintry day. I think it needs a little more flavor and will try it with Italian sausage next time.
Beth says
