Quick and Easy Stuffed Pepper Soup

I love a good stuffed pepper recipe like my Philly cheesesteak stuffed peppers and pizza stuffed peppers. However, soup season is here, and I’m ready to embrace the warm, cozy flavors that come with it!

So, I’m transforming one of my favorite meals into a comforting soup with this crockpot stuffed pepper soup recipe! It has been a favorite of mine for quite a while because it’s hearty, flavorful, and so simple to make.

Ingredients Needed and Substitutions

*Scroll down to the recipe card for the full recipe and ingredient list!

  • Avocado Oil: I prefer the neutral flavor of avocado oil, but olive oil will also work.
  • Ground Beef: You’ll need 1 pound of ground beef for this recipe. I prefer to use lean ground beef, but any fat percentage will work. Feel free to substitute ground turkey or ground chicken if preferred.
  • Fresh Veggies: Green or red bell peppers and onions add flavor and nutrients, recreating the classic stuffed pepper taste. 
  • Canned Tomatoes: We’re using canned tomato sauce and canned diced tomatoes to form the base of the soup. 
  • Stock: Use beef stock or chicken stock. You can also substitute vegetable stock if needed. 
  • Coconut Sugar: I like to include a pinch of sugar to balance the acidity of the tomatoes, but you can omit it to keep this recipe Paleo-friendly and Whole30. 
  • Seasonings: You’ll need garlic powder, black pepper, salt, and paprika. 
  • White Rice: Feel free to substitute cauliflower rice for a low-carb option.

FAQs

Can I make this recipe on the stovetop? 

Absolutely! To do so, brown the beef in oil a skillet, and drain all but one teaspoon of oil. Next, add the peppers and onions, and cook to soften. Then, stir in the remaining ingredients, and simmer until the veggies are tender and the rice is cooked through.

How long do leftovers last? 

Leftover soup will stay fresh in an airtight container in the fridge for up to 5 days. 

Can I freeze this soup? 

Yes! You can freeze leftovers for up to 1 month. Let the soup cool completely, and transfer it to a freezer-safe container to store. Or, pour individual portions into souper cubes, and transfer them to a sealable bag. Then, you can just pull out a cube or two when you’re ready to serve! 

Can I use leftover rice?

Yes, this recipe is a great way to use up any cooked rice you have on hand. Cook the other ingredients as normal. Then, stir in the white or brown rice, letting it cook just long enough to warm through.

    Excellent recipie. I received lots of peppers this week in my organic veggie box. This was a great way to use them up. My husband who doesn’t like peppers enjoyed the soup very much. Will definitely be making this again

  2. 5 stars
    I love this soup. Made it several times. Always in the Instant Pot. So flavorful. I substitute beyond beef.

  3. 5 stars
    I made this the other day but substituted ground turkey for ground beef. It was amazing! I kept the seasonings the same, which I think helped me to not miss the richer flavor of the beef. It’s also SO easy to make – not a lot of ingredients and not a lot of active cooking time. 10 out of 10. Will make again!!!

  4. 5 stars
    I have a very picky teenager and she loved this. It was amazing! I would probably cut the recipe in 1/2 as there are only three of us and we had a ton left.

  5. 5 stars
    This recipe is one of my absolute favorites from Lexi’s Clean Kitchen! I have easily made it a dozen times since finding it and both myself and my husband are big fans. I have always used my insta-pot when making and I sub with ground turkey, it’s awesome that I only have to dirty 1 pot!

    1. Brown rice takes significantly longer to cook for white rice and can’t be swapped exactly the same as white rice.
