Featured Ingredients
- Potatoes - I love to use Yukon Gold Potatoes. The skin is tender and thin.
- Bacon - Because everything is better with bacon, including potato soup! it adds so much flavor.
- Italian Turkey Sausage - Using turkey sausage decreases the amount of grease and calories in this soup. Try it. You won’t be able to tell it isn’t pork sausage. Make sure you find a brand without any high FODMAP ingredients. I have used the Jennie-o brand with success.
- Chicken Broth - Use homemade, a low FODMAP broth version, or a soup base and water.
- Kale - Use fresh kale with the stems removed. In a pinch, I have also used chopped frozen kale. It doesn’t have the large pieces of kale like using fresh does. It turns the soup almost green with many tiny pieces of kale. It's still delicious. It just looks different.
- Spices: - Kosher Salt, Ground Black Pepper, Crushed Red Pepper Flakes
- Green Onion Tops - Just the top of the spring onion. The white part is where the fructans hide.
- Garlic-Infused Oil - Add the flavor of garlic without actual garlic.
- Heavy Cream - Did you know heavy cream is more fat than lactose? I also have used lactose-free milk and unsweetened almond milk with success.
- Fresh Lemon Juice - Just a touch of lemon juice to balance out the richness of this soup.

Step-By-Step Instructions
Step 1: Cut bacon strips into 1-inch pieces. Use kitchen shears to make it an easy job!. Then, in a 5-quart heavy-bottomed Dutch oven pan or a large pot, fry over medium heat until the fat is rendered out and cooked. Remove the bacon and drain on a paper towel-lined plate.
Step 2: With a paper towel, soak up any bacon grease. However, if you want to keep all that flavor, feel free to skip that step.
Step 3: Next, add the Italian turkey sausage. With a meat chopper, break the turkey sausage into smaller pieces. Cook until there are no pink pieces.
Step 4: While the sausage is cooking, wash and chop up the potatoes into ½ inch cubes.
Step 5: Add the potatoes and chicken broth to the Dutch oven and turn up the heat to medium.
Step 6: Next, add the green onions, salt, black pepper, and crushed red pepper flakes. Simmer for fifteen minutes or until potatoes are fork-tender.
Step 7: Next, wash and remove the middle stems from the kale. Tear into the small pieces and add to the soup. Cook for 2-3 minutes or until wilted.
Step 8: Once the kale is wilted, remove the soup from the heat and add the heavy cream, garlic oil, and lemon juice. Stir.
Serve immediately. Top with shaved parmesan cheese and fresh ground black pepper.
Tips and Tricks
Cut the potatoes into cubes! If you slice the potatoes, the skins eventually fall off and become almost like noodles.
Turkey sausage has more water than pork sausage. Do not be alarmed. It will dissipate as it cooks.
Use the remaining bacon to make BBQ bacon chicken or a spinach salad with mandarin oranges!
Ingredient Swaps
- Sausage Options - Feel free to use homemade Italian sausage made out of ground pork.
- Bacon Option - Use turkey bacon for a lower-calorie option.
- Heavy Cream - Swap with half-n-half, Whole, 2% or 1% Milk. I would not use skim milk.
- Green Onions - Use chopped leeks instead of green onions. Use only the green parts of the leek.
- Baby Spinach - Swap out the kale for fresh baby spinach.
Variations

Alternative Cooking Methods
Slow Cooker Potato Soup With Sausage:
- In a large 6-quart slow cooker or crock pot, add the cooked bacon, turkey sausage, broth, spices, and chopped potatoes.
- Cook on low for six-eight hours or high for 3-4 hours.
- Once the potatoes are fork-tender, add the kale, green onions, garlic oil, heavy cream, and lemon juice. Remove from heat and serve.
Instant Pot Potato Soup With Sausage:
- Turn the Instant Pot to saute, fry the bacon, remove and drain.
- Fry the sausage.
- Next, add the chicken broth and scrape the bottom of the pot to remove any burned-up bits.
- Add the chopped potatoes, bacon, sausage and spices.
- Cook on high pressure for 5 minutes.
- Quick release the pressure, remove the cover, add the torn pieces of kale, and allow to wilt for about 1-2 minutes.
- Then add the heavy cream, green onions, garlic oil, and lemon juice.
- Remove from the heat and serve.
Storing And Reheating
Store: Keep any leftovers in an airtight container in the refrigerator for up to four days.
Reheat: Pour soup into a microwave-safe bowl and heat for 1-2 minutes, stirring halfway between cooking time. Another option is to heat in a small saucepan over low heat, stirring.
Freeze: Place completely cooled soup into a freezer-friendly container. If you use any other type of dairy besides heavy cream, I would not recommend freezing it. Dairy does not freeze well, except for dairy that has a high-fat content.

FAQs
Soups can be greasy when the ingredients such as bacon or sausage, have a higher fat content. If a soup is too greasy, chill the soup overnight and scoop out the solidified clumps of grease with a spoon. Discard in the garbage, not down the sink! Grease is awful for pipes. This process is the easiest way to reduce the amount of grease in soup.
Purchase chopped kale from the produce department. There is also a chopped frozen kale option. However, it will turn the soup more of a green color than when using fresh kale.
What To Serve With This Soup
Add a slice of low FODMAP cornbread and a leafy green salad with homemade Italian dressing. If serving many people, add a side dish of oven-roasted vegetables for a hearty meal.
