How to Make Slow Cooker Potato Leek Soup Recipe
Step 1: Sauté the Leeks
Start by slicing the leeks and discarding the thick green ends. In a large skillet, melt the butter over medium-high heat, then add in the garlic and leeks. Sauté until the leeks are softened—this step brings out their sweetness, adding depth to your soup.
Step 2: Combine Ingredients in Your Slow Cooker
Once your leeks are ready, transfer them into your slow cooker along with peeled (if preferred) yukon gold potatoes, bay leaves, thyme, salt, and pepper. These ingredients will meld beautifully as they cook together.
Step 3: Add Chicken Broth
Pour in the chicken broth until everything is covered. Give it a gentle stir before closing the lid tightly. Set your slow cooker on high for 5 hours or low for 8 hours—let those flavors develop!
Step 4: Blend Your Soup
After cooking time is up and potatoes are tender, carefully remove any fresh thyme sprigs as well as bay leaves. Using an immersion blender (or transferring batches to a food processor), blend until smooth but don’t overdo it; we want some texture!
Step 5: Finish with Cream
Stir in the heavy cream for that luscious finish! Blend just enough to combine everything nicely before serving hot, garnished with fresh chives on top. Pair it with crusty bread for an unforgettable meal!
Now that you have all these steps laid out, I can’t wait for you to enjoy this delightful bowl of soup! Happy cooking!
Pro Tips for Making Slow Cooker Potato Leek Soup Recipe
Making a delicious potato leek soup is easier than you think, and with these handy tips, you’ll be a pro in no time!
- Use fresh leeks: Fresh leeks enhance the flavor of your soup significantly. Look for leeks with bright green tops and firm, white stalks for the best taste.
- Peel or not to peel?: Peeling the potatoes is optional! Leaving the skin on can add extra nutrients and texture to your soup, but if you prefer a creamier consistency, feel free to peel them.
- Don’t rush the blending: When blending the soup, take your time. A few chunky bits can add character to your soup, making it more rustic and hearty.
- Adjust seasoning to taste: Everyone’s palate is different. After blending, taste the soup and adjust salt and pepper as needed before adding cream.
- Make it ahead: This soup keeps well in the fridge for up to 3 days or can be frozen for up to 3 months. Reheat gently on the stove when you’re ready to enjoy it again!
