Essential Concepts

Use waxy or all-purpose potatoes, cut into even pieces. Add dairy near the end to prevent curdling. Cook until the potatoes are tender, then adjust the seasoning before serving.

Why This Soup Works

A slow cooker gives the ham and vegetables time to season the broth gradually. The potatoes release some starch as they cook, which gives the soup a lightly thickened body without requiring a flour-based sauce.

Carrots and celery add sweetness and aroma, while onion provides a savory foundation. This recipe uses cooked ham, so it is especially useful after a holiday meal.

Diced ham remains pleasantly firm during the cooking process, while a ham bone can add deeper flavor if the slow cooker is large enough. Remove the bone before serving and pick off any remaining meat.

For the best texture, choose potatoes that hold their shape reasonably well. Yukon Gold potatoes are a dependable choice because they become creamy without disintegrating quickly.

Russet potatoes create a thicker soup but may break apart more readily. Red potatoes retain their shape and contribute a slightly firmer bite.

Slow Cooker Ham and Potato Soup Recipe

Yield and timing

• Servings: 6
• Preparation time: 20 minutes
• Cooking time: 6 to 7 hours on low or 3 to 4 hours on high
• Slow cooker size: 5 to 6 quarts

Ingredients

• 2 pounds Yukon Gold or red potatoes, peeled if desired and cut into 1-inch cubes, about 900 g
• 2 cups diced cooked ham, about 300 g
• 1 medium yellow onion, diced, about 150 g
• 2 medium carrots, sliced, about 150 g
• 2 celery stalks, sliced, about 100 g
• 3 garlic cloves, minced
• 4 cups low-sodium chicken broth, 946 mL
• 1 cup whole milk, 240 mL
• 1 cup half-and-half, 240 mL
• 1 teaspoon kosher salt, or to taste, about 5 g
• 1/2 teaspoon black pepper, about 1 g
• 1/2 teaspoon dried thyme, about 1 g
• 1 bay leaf
• 2 tablespoons chopped fresh parsley, about 8 g
• 2 tablespoons unsalted butter, optional, about 28 g

Instructions

1. Place the potatoes, ham, onion, carrots, celery, and garlic in the slow cooker.
2. Pour in the chicken broth. Add the salt, black pepper, dried thyme, and bay leaf. Stir gently to distribute the ingredients.
3. Cover and cook on low for 6 to 7 hours or on high for 3 to 4 hours. The soup is ready when the potatoes can be pierced easily with a fork.
4. Remove the bay leaf. Use a potato masher to crush a small portion of the potatoes directly in the slow cooker. This thickens the broth while leaving plenty of potato pieces intact.
5. Stir in the milk and half-and-half. Add the butter if using. Cover and cook on high for 15 to 20 minutes, just until the dairy is heated through. Do not allow the soup to boil.
6. Taste and adjust the salt and pepper. Stir in the parsley immediately before serving.

Optional thickening method

For a thicker soup, combine 2 tablespoons of cornstarch with 3 tablespoons of cold water, or 16 g cornstarch with 45 mL water. Stir the mixture into the finished soup, cover, and cook on high for 15 to 20 minutes.

The soup should thicken as it heats. Add the slurry gradually because the potatoes already provide some natural thickening.

Practical Cooking Tips

Cut the potatoes into pieces of similar size so they finish cooking at the same time. Pieces that are too small may dissolve before the larger pieces are tender.

Avoid opening the slow cooker repeatedly because each opening releases heat and can extend the cooking time.

Use low-sodium broth when possible. Ham varies considerably in salt content, and adding too much salt early can make the finished soup unpleasantly salty. Season again after the dairy has been added.

Dairy should be added near the end. Long cooking can cause milk or half-and-half to separate, especially at high heat.

Whole milk provides a lighter soup, while half-and-half gives it a richer texture. Heavy cream may be substituted for part of the half-and-half, though it will produce a heavier result.

For a more pronounced herb flavor, add a small sprig of fresh thyme during cooking and remove it with the bay leaf.

Chopped green onions, shredded cheddar, or a small amount of sour cream can be used as toppings, but the soup is flavorful without them.

Storage and Reheating

Cool the soup promptly and refrigerate it in a covered container for up to 4 days. The potatoes may absorb additional broth during storage, so add a splash of milk or chicken broth when reheating.

Warm individual portions in the microwave in short intervals, stirring between each interval. For larger amounts, reheat the soup in a saucepan over medium-low heat and stir frequently.

Freezing is possible, although dairy-based potato soups may change texture after thawing. For better results, freeze the soup before adding the milk and half-and-half.

Thaw it in the refrigerator, reheat it gently, and add the dairy near the end.

Serving Suggestions

Serve the soup with crusty bread, cornbread, or a simple green salad. This rosemary Parmesan cornbread recipe makes a flavorful pairing for the creamy soup.

A light vegetable side balances the soup’s starch and salt. For lunch, pair a small bowl with sliced fruit or a sandwich.

Leftover soup can also serve as a filling main course because the ham supplies protein and the potatoes provide substantial energy.

FAQ’s

Can raw ham be used?

Yes, but the cooking time and food safety requirements change. Cooked ham is preferable for this recipe because it is ready to eat and seasons the soup without requiring additional preparation.

If using raw ham, verify that it reaches a safe internal temperature and is fully tender before serving.

Can I make this soup without dairy?

Yes. Replace the milk and half-and-half with additional chicken broth, unsweetened oat milk, or a small amount of coconut milk. Coconut milk will add a noticeable flavor, while broth keeps the taste closest to the original recipe.

Why are my potatoes still firm?

Potato size, slow cooker temperature, and the age of the appliance can affect cooking time. Continue cooking until the potatoes are fork-tender.

Avoid adding acidic ingredients before the potatoes soften, since acidity can slow their cooking.

Can I add cheese?

Yes. Stir in 1 to 2 cups of shredded cheddar, or 115 to 225 g, after the dairy has been heated. Add the cheese gradually and stir until melted.

Reduce the added salt because ham and cheese can both contain substantial sodium.

How can I make the soup less salty?

Add unsalted broth, milk, or water in small amounts. Additional potatoes can also dilute the salt, though they will need time to cook.

Avoid relying on a whole raw potato to remove salt, since it does not selectively extract sodium.

Can I prepare it without a slow cooker?

Yes. Simmer the vegetables, potatoes, ham, broth, and seasonings in a covered stockpot for about 20 to 25 minutes, or until the potatoes are tender.

Add the dairy during the final few minutes and keep the soup below a boil.
