Key Ingredients
Just 8 ingredients in this simple keto soup. Here are notes on key ingredients.
- Andouille Sausage: We always buy Aidells since it uses simple, quality ingredients in it's smoked sausages. Aidells is a little more expensive than other smoked sausages, but you get what you pay for and their sausages are delicious! In this recipe, we use Aidells Cajun Style Andouille Sausage since it's a little spicy and low in carbs (1 net carb per link). You can use another flavor of smoked sausage if you prefer, such as Italian.
- Rao's Arrabbiata Sauce: We use Rao's pasta sauce (the BEST low-carb sauce out there!) as a shortcut ingredient in this soup, which makes it full of flavor. We use Arrabbiata Sauce since it's spicier than marinara and adds a little heat. Don't worry, it doesn't make it too spicy — just enough to give it depth of flavor. You may use another low-carb arrabbiata or marinara sauce if you prefer. Just be sure to check the net carbs as different brands and flavors may have more carbs.
- Heavy cream: Heavy cream is a must for deliciously creamy soup!
- Chicken broth: Chicken broth helps thin the soup (without adding any carbs!) and enhances the flavor. If you prefer, you could also use vegetable broth.
- Bell pepper: You can use red or green bell peppers in this recipe.
- Mushrooms: We use white, pre-sliced mushrooms to make it easy. You may use cremini or another type of mushroom if you prefer.
