This soup has a huge range of wonderful flavors thanks to the various ingredients. The soup is loaded with beef, rice, herbs, tomato, and bell peppers. If you love the traditional stuffed peppers, you will likely love this recipe too.

Below we will touch on some of the different ways you can serve this soup and a few ideas on how you might want to adjust the recipe.

Serving Ideas for Stuffed Pepper Soup

This soup is delicious enough that it does not require extra side dishes or garnishes. However, if you want to go one step further, I have a few suggestions below.

This soup will go down a treat with a couple of slices of homemade bread. If you do not have the time, then an artisan loaf of sourdough from a bakery is a good choice. Otherwise, plain bread or croutons will also be nice.

After serving the soup, you can top it with shaved parmesan or cheddar cheese. The cheese will add a delicious cheesy element to the soup, but not everyone may like it. Another idea is to top the soup with a dollop of sour cream or double cream.

Adjusting the Recipe

There are a few things that you can do to adjust the recipe to make it easier or more to your liking. I will go through a few suggestions on what you can do below.

You can try adding more vegetables to the soup for even more flavor, for example, mushrooms, celery, carrots, or even chickpeas. I recommend dicing any extra vegetables rather than cutting them into chunks.

Browning the beef is an optional but recommended step. By browning the beef, you can reduce the amount of fatty liquid in the soup. However, it is one extra dish and step which you can easily skip if you do not mind a bit of extra greasy liquid in your soup.

You do not need to use ground beef in the recipe. Other options, such as ground pork, chicken, or lamb, will work fine in the recipe. You could even use chickpeas as a replacement for the ground meat.

I add the rice at the start, but this may cause the rice to go a bit mushy and thicken the soup beyond what you prefer. If this is the case, add the rice fifteen minutes before serving. Also, if you are looking for a low-carb option, try using cauliflower rice instead.

Recipe Tips

  • I add the rice at the start of cooking to help thicken the liquid. However, if you prefer your soup to be more liquid and less grainy, you can add the rice fifteen minutes before serving.
  • Ground beef is also known as beef mince or hamburger in some countries.
  • You may need to season the soup generously but be careful not to go overboard with the salt and pepper. I recommend tasting it as you season so you can get it to the perfect taste.
  • Other types of ground meat will work in this recipe. For example, ground pork, chicken, or even lamb will work nicely with the other flavors in this recipe.
  • I recommend using cooked rice, as uncooked rice may turn the soup too thick. Ensure the cooked rice is fresh or has been stored correctly in the refrigerator before use.

Note: I use a 5.5L (6 Quart) slow cooker (Amazon | Walmart) for all the recipes that I have on this website unless specified. If you have a smaller or larger slow cooker, then you might need to adjust the ingredients.
