Ingredients You’ll Need
- 2 tablespoons butter: Adds richness to the soup’s base. You can use unsalted butter for better control over your seasoning.
- 1 tablespoon olive oil: Helps sauté the vegetables and adds a light flavor. Feel free to substitute with avocado oil for a different taste.
- 1 small onion, chopped (70g / 2.5oz): Provides a wonderful foundation for flavor. Yellow or white onions work best.
- 2 medium leeks, washed and sliced (500g / 17.6oz): These give a slightly sweet, mild onion flavor. Clean thoroughly to remove grit.
- 2 ribs celery, diced: Adds a nice crunch and aromatic flavor. You can swap with green bell pepper if you prefer.
- 3 potatoes, peeled and cut into 2cm cubes (400g / 14oz): Yukon Gold or Russet are perfect for that creamy texture. Avoid waxy potatoes, as they won’t break down well.
- ½ teaspoon dried Italian herbs: A blend of herbs like basil, oregano, and thyme brings depth to the flavor.
- 1 liter vegetable or chicken stock: Forms the soup’s flavorful base. Use low-sodium stock for better control over saltiness.
- ¼ cup milk: Adds creaminess. Whole milk is best, but you can use a non-dairy alternative if needed.
- ¼ cup heavy cream: Intensifies the creamy texture. Light cream can be a substitute if you’re looking for fewer calories.
- 1 teaspoon salt: Adjust based on your stock’s saltiness.
- ½ teaspoon black pepper: For a touch of heat; feel free to use white pepper for a milder flavor.
- Cooked bacon, chopped: Provides added crunch and savory flavor. Vegetarian bacon works for a meatless option.
- Parmesan or cheddar, for serving: Adds a cheesy kick. Grated cheeses melt beautifully on top!
- Drizzle of cream and olive oil: Perfect finishing touches for serving.
- Parsley or chives: Fresh herbs add vibrant color and freshness.
How to Make Slow Cooker Potato Soup
Melt the Butter and Oil: In a non-stick frying pan over medium heat, melt 2 tablespoons of butter with 1 tablespoon of olive oil. Add 1 small chopped onion, 2 sliced leeks, and 2 diced celery ribs, sautéing them for 4-5 minutes until softened and fragrant.
Combine Ingredients: Transfer the sautéed vegetables into your slow cooker. Add 3 peeled and cubed potatoes (cut into 2cm cubes), ½ teaspoon of dried Italian herbs, 1 liter of vegetable or chicken stock, and finally season with 1 teaspoon of salt and ½ teaspoon of black pepper. Stir to ensure everything is well mixed.
Cook the Soup: Cover the slow cooker and cook on high for 4-5 hours or on low for 6-8 hours, until the potatoes are fork-tender. The longer they cook, the more flavorful and creamy your soup will be.
Blend Until Smooth: Once the potatoes are tender, blend the soup until smooth using either a traditional blender or an immersion blender. If you prefer a chunkier texture, reserve some potato pieces and mix them back in after blending.
Add Creaminess: Stir in ¼ cup of milk and ¼ cup of heavy cream until you reach your desired consistency, creating that rich, creamy texture we all love. Adjust the seasoning to taste, adding more salt or pepper if needed.
Serve Warm: Ladle the soup into bowls and top with cooked and chopped bacon, a sprinkle of grated Parmesan or cheddar, a drizzle of cream, and olive oil. Garnish with fresh parsley or chives to add a pop of color, bringing your slow cooker potato soup to life.
Storing & Reheating
To store your slow cooker potato soup, make sure it has cooled to room temperature before placing it in an airtight container. In the refrigerator, it will stay fresh for about 3-5 days. You can also freeze the soup in a freezer-safe container for up to 3 months. When you’re ready to enjoy it again, reheat on the stovetop over low heat for about 10-15 minutes, stirring occasionally until warmed through. The texture might be slightly different, but a splash of milk or cream can help refresh the creaminess.
Chef’s Helpful Tips
- Avoid burning the onions and leeks by keeping the heat moderate when sautéing.
- Use cold stock as opposed to warm stock to maintain the right cooking temperature in your slow cooker.
- If you prefer a smoky flavor, try adding smoked paprika or a splash of liquid smoke to the mix.
- For thicker soup, use a potato masher after blending to break down the remaining potato pieces further.
- If you want leftovers, make a double batch; it freezes beautifully for easy future meals.
This slow cooker potato soup is a delightful way to make mealtime easy without sacrificing flavor. With just a handful of ingredients and that lovely slow-cooked warmth, it promises comfort for everyone at the table. Don’t hesitate to play with the ingredients and add your personal touch, whether that’s extra herbs, more cream, or whatever comforts your taste.
