Ingredient Notes

Ingredients needed for stuffed pepper soup.
  • Ground beef. You can use any fat percentage of ground beef here or even ground turkey.
  • Peppers. We used a combination of red and green bell peppers to give this soup a variety of colors.
  • Tomato paste thickens this stuffed pepper soup while adding tangy flavor.
  • Beef broth creates the liquid base for this soup. Some broth varieties have added sugars or flour, so make sure to check the label.
  • Diced tomatoes. Use canned undrained tomatoes. The liquid combined with beef broth and tomato paste to give the soup a perfect consistency.
  • Cauliflower rice. We add riced cauliflower to the soup just before serving. You can also use Banza rice (made from chickpeas) in this soup. If using Banza, add it to the pot in the last 30 minutes of cooking.
  • Mozzarella cheese. This is an optional topping but really makes the soup taste more like stuffed peppers!

Stove Top Directions

Need to get dinner on the table fast? Make Stuffed Pepper Soup in a Dutch oven instead.

  1. Brown the ground beef in the Dutch oven on the stove top. Drain the excess grease, then return the beef to the pan. Add the diced vegetables, tomatoes, tomato paste, beef stock and seasoning.
  2. Cover the soup and cook on low for 1 hour. Stir in the cauliflower rice before serving.

Serving Suggestions

  • Add shredded mozzarella and fresh chopped parsley to each bowl of soup. Fresh grated parmesan would be delicious too!
  • I love this hearty soup with a light green salad on the side. Toss together some leafy greens with a sugar free dressing and you’re good to go.

Recipe FAQs

Do I have to brown the ground beef first?

Yes, browning the ground beef before slow cooking is a must. It prevents the beef from clumping and keeps the excess grease out of your soup.

Is this stuffed pepper soup keto?

Yes, this soup is low in net carbs and keto approved! Make sure to check the labels on your packaged and canned ingredients to make sure there are no added sugars sneaking their way into your soup.

What’s the best way to store this soup?

Leftovers can be transferred to an airtight container and kept in the fridge for about 3 days.
You can freeze this soup for longer storage too. Let the frozen soup thaw in the fridge overnight then reheat in the microwave or on the stove for a quick and easy lunch.
