This Keto Sausage Soup with Peppers and Spinach combines warm spices, savory sausage, and bright vegetables for a comforting low-carb meal. Includes stovetop and Instant Pot instructions.
Keto Sausage Soup with Peppers and Spinach
As temperatures cool, hearty soups become a go-to. This Keto Sausage Soup is a fast, flavorful, low-carb option that doesn’t need to simmer all day to develop deep taste. Savory pork sausage, roasted-style Poblano and red peppers, aromatic celery, and a warm spice mix come together with chicken stock and fresh spinach for a satisfying bowl in under an hour.
The spice blend—basil, oregano, rosemary, chili powder, cumin and a pinch of cinnamon—gives the soup a balanced warmth without overwhelming heat. If you want a bit more kick, add more chili powder or a touch of crushed red pepper. Serve with shredded sharp cheese on top for richness, or enjoy as-is for a lighter bowl. Leftovers keep very well and the flavors often improve after a day in the fridge.
Instant Pot or Stovetop
This recipe works perfectly on the stovetop or in an electric pressure cooker. For the Instant Pot, use the Sauté function to brown the sausage and soften the vegetables, then switch to Soup or Manual mode for the cooking time. On the stovetop, brown the sausage in a large pot, add vegetables and spices, pour in stock and simmer until the flavors meld. Both methods yield a rich, aromatic soup.

Ingredients
- 2 tbsp olive oil
- 1 lb pork sausage
- 1 medium red pepper, diced
- ½ medium Poblano pepper, diced (substitute Anaheim or roasted poblanos if needed)
- 3 celery stalks, diced
- 1 tsp dried basil
- 1 tsp dried oregano
- 1 tsp dried rosemary
- 1½ tsp chili powder
- 1 tsp ground cumin
- ½ tsp ground cinnamon
- Salt and black pepper, to taste
- 6 cups organic chicken stock or bone broth
- 2 cups baby spinach
- 1 cup sharp cheese, grated (optional, for topping)
Instructions
- Heat the olive oil in a large soup pot or Dutch oven over medium-high heat. Add the sausage and cook until no longer pink, about 5 minutes. Break the sausage into bite-size pieces as it cooks.
- Instant Pot: Use the Sauté function to complete step 1 inside the pressure cooker.
- Add the diced red and Poblano peppers, celery, and all dried herbs and spices. Season generously with salt and black pepper. Cook, stirring occasionally, until the vegetables soften, about 5–6 minutes. (In the Instant Pot, sauté for about 1 additional minute after adding the vegetables.)
- Pour in the chicken stock and bring to a simmer. On the stovetop, simmer for 20 minutes, stirring occasionally. Add the spinach and cook 4–5 minutes more, just until the spinach wilts. Instant Pot: Add the stock and spinach, close the lid and set to Soup mode or 10–12 minutes on Manual. Allow a 10-minute natural pressure release before opening.
- Remove from heat and serve immediately. Top with grated sharp cheese and extra diced Poblano if desired. Enjoy.
Notes
Poblano peppers are sometimes sold canned or roasted. If you use dried ancho or dried poblano chilies, rehydrate them in hot water before dicing and adding to the soup. Anaheim peppers are a mild, easy substitute. Adjust chili powder to taste for more or less heat.
Recommended items (examples)
