Tip: save now, make later.

The broth smells rich before the potatoes are even tender, but the best part is the way their edges soften into the soup while the cubes hold their shape. I like this slow cooker creamy sausage and potato soup for the nights when I want a hearty bowl without tending a pot on the stove.

Russet potatoes give the broth a little body, and Italian sausage brings plenty of seasoning to every spoonful. The kale adds a fresh, hearty bite, while cream rounds everything out at the end. Let the slow cooker do the long stretch of cooking, then finish the soup with its greens and cream for a comforting, creamy bowl.

The Sausage Gets Its Flavor Before It Ever Reaches the Slow Cooker

A slow cooker can soften ingredients beautifully, but it won’t brown sausage. That difference matters here: browning builds savory flavor on the meat, and the browned bits left in the skillet season the onion as it softens. The soup tastes fuller because that work happens before the long, gentle cook begins.

Break the bulk sausage into small pieces as it cooks so you get browned edges throughout instead of one large, steamed mass. Once the meat is browned, drain off excess fat; leaving a heavy layer behind can make the finished broth feel greasy. Then cook the onion in the same skillet, where it picks up some of the sausage’s browned flavor. This small amount of stovetop cooking is what gives the slow cooker a head start on a savory base.

It also gives you a chance to cook the garlic briefly rather than leaving it to simmer for hours. Garlic can turn muted during a long cook, so adding it to the softened onion just before everything moves to the slow cooker keeps its aroma present in the finished soup.

Why Russets, Heavy Cream, and Kale Each Have a Specific Job

• Italian sausage — Bulk sausage breaks into spoon-sized bites and seasons the broth as it cooks. A fresh package is fine; the main thing is choosing sausage you enjoy, since its herbs and seasoning carry through the whole pot.
• Russet potatoes — Their starch gives the broth more body as the cubes cook. Cut them evenly so they soften at about the same pace, and peel them for the smooth, tender texture this soup is meant to have.
• Low-sodium chicken broth — Sausage already brings seasoning, so a lower-sodium broth lets the potato and kale stay balanced rather than making the soup too salty. The broth’s quality matters less than keeping it low-sodium.
• Heavy cream — Its richness makes the broth creamy without needing a separate thickener. Choose heavy cream rather than a thin milk if you want the soup to keep its full texture.
• Kale — Chopped leaves hold their shape better than delicate greens in a hot soup. Remove the tough stems and chop the leaves so they fit comfortably on a spoon.
• Yellow onion and garlic — Together they give the sausage base a mellow, savory foundation. Fresh garlic has a brighter aroma, but there is no need to seek out a specialty variety.

Build the Sausage Base, Then Let the Slow Cooker Handle the Potatoes

Brown the Sausage Until It Has Color

Set a large skillet over medium-high heat and cook the bulk Italian sausage for 8 to 10 minutes, breaking it into small pieces as it browns. Look for browned edges and no pink in the center, and use a thermometer to confirm it reaches 160°F. Drain the excess fat so it doesn’t leave an oily layer on the soup. If the sausage is crowded into large clumps, break it up before moving on.

Soften the Onion and Wake Up the Garlic

Add the chopped onion to the skillet and cook over medium heat for 3 to 4 minutes, until softened. Stir in the minced garlic and cook for 30 seconds, just until fragrant. Garlic cooks quickly, so keep it moving rather than letting it sit against the hot pan. The sausage, onion, and garlic then go together into the slow cooker.

Slow-Cook the Potatoes Until Tender

Stir the sausage mixture together with the peeled, cubed potatoes, chicken broth, kosher salt, and black pepper in a 6-quart slow cooker. Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours. The potatoes are ready when a fork slides through a cube without resistance. If a few cubes are still firm, give them more time rather than judging doneness by the clock alone.

Finish with Cream and Wilted Kale

Stir in the heavy cream and chopped kale, cover, and cook on HIGH for 20 to 30 minutes, until the kale is wilted and the soup is hot. The leaves should look softened and darken as they settle into the broth. Stir well before serving so the cream is evenly distributed. Don’t leave the kale in for the full slow-cooking stretch; it needs only this finishing time.

Ingredients Equipment Method Notes

Ingredients

  

• 1 lb Italian sausage bulk

• 2 lb russet potatoes peeled and cut into 1/2-inch cubes
• 6 cup low-sodium chicken broth
• 1 tsp kosher salt
• 0.5 tsp black pepper
• 1 cup heavy cream
• 4 cup kale chopped, tough stems removed

Equipment

• 1 large skillet
• 1 6-quart slow cooker

Method

 

1. In a large skillet over medium-high heat, cook the sausage, breaking it into small pieces, for 8 to 10 minutes until browned and it reaches 160°F.
2. Drain excess fat.
3. Add the onion to the skillet and cook over medium heat for 3 to 4 minutes until softened.
4. Stir in the garlic and cook for 30 seconds.
5. Transfer the sausage mixture to a 6-quart slow cooker and stir in the potatoes, chicken broth, salt, and pepper.
6. Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours, until the potatoes are tender.
7. Stir in the heavy cream and kale, cover, and cook on HIGH for 20 to 30 minutes, until the kale is wilted and the soup is hot.

Notes

Cut the potatoes into evenly sized cubes so they cook at the same rate. Refrigerate leftovers for 3 to 4 days; freezing is not recommended because the cream may separate. For a lighter soup, half-and-half can replace the heavy cream.
