Ingredients Breakdown for Simple Potato Leek Soup

Let’s Get Cooking!
Step-by-Step Instructions
Melt the Butter : In a large pot, melt the butter over medium heat. You’ll know it’s ready when it starts to foam just a bit!
Sauté the Leeks : Add the sliced leeks and sauté them until they’re softened, which will take about 5-7 minutes. They should be translucent, gorgeous and caramelized.
Add Garlic for Fragrance : Next, toss in the minced garlic and sauté for an additional minute until fragrant. Oh, the smell is heavenly!
Toss in Your Potatoes : Stir in the diced potatoes, followed by pouring the vegetable broth over everything. Give it a good stir.
Bring to a Boil : Turn up the heat and bring the pot to a boil. Once it starts bubbling, reduce the heat and let it simmer until the potatoes are tender, around 15-20 minutes.
Blend Until Smooth : Grab your immersion blender and blend the soup until smooth. If you don’t have one, carefully transfer it to a regular blender in small batches. So creamy, seriously!
Season to Perfection : Sprinkle in a couple pinches of salt and pepper, and stir in the cream if you’re using it.
Serve and Garnish : Serve warm, garnished with fresh herbs if you have them. You can almost hear the “oohs” and “aahs” from your family at this point!
