Preparing Roasted Garlic Potato Soup
Making a bowl of hearty roasted garlic potato soup is a delightful culinary journey that promises to warm both your heart and your stomach. This step-by-step guide will walk you through the process, ensuring you create a creamy, flavorful soup that’s simply irresistible. Ready to roll up your sleeves? Let’s dive in!
Roast the Garlic
Start by preheating your oven to 375ºF. Take a whole head of garlic and slice off the top to expose those cloves. A drizzle of olive oil and a sprinkle of salt and pepper will enhance the sweetness of the garlic as it roasts. Wrap the garlic in foil and place it on a baking sheet, popping it into the oven for about 40-45 minutes. You'll know it’s done when it’s tender and fragrant. Let it cool before you squeeze out the luscious roasted goodness!
Boil the Potatoes
While that garlic is transforming in the oven, bring a large pot of water to a boil. Peel and cube 1¾ pounds of russet potatoes and add them to the boiling water. Cook until they’re tender, which should take about 15 minutes. Once done, drain the potatoes and allow them to cool slightly before cubing them again—this will help achieve a smoother soup texture.
Sauté the Onions and Leeks
In your trusty Dutch oven, melt 4 tablespoons of salted butter over medium-high heat. Toss in 1 cup of chopped white onions and 1 thinly sliced leek (just the whites and light greens). Sauté for 6-8 minutes until they become translucent and fragrant. The sweet aroma of sautéed onions and leeks is simply amazing; trust me, your kitchen will smell heavenly!
Make the Soup Base
Lower your heat to medium and stir in 3 tablespoons of flour, cooking it for about 60-90 seconds until it turns lightly golden. Gradually add 4 cups of low-sodium chicken broth (or vegetable broth if you prefer) along with 1 cup of whole milk and ¼ cup of heavy cream. Season with ½ teaspoon of fresh thyme, a pinch of salt, and pepper. Let everything come to a gentle boil, then reduce the heat and allow it to simmer for a couple of minutes until it starts to thicken.
Blend the Soup to Perfection
Here comes the fun part! Using an immersion blender, puree the soup until it’s beautifully smooth. If you don’t have an immersion blender, transfer the mixture in batches to a traditional blender. If the soup is thicker than you like, don't shy away from adding more chicken broth—this isn’t a one-size-fits-all deal when it comes to soup consistency. Taste and adjust seasoning before serving.
Serve and Garnish
Finally, ladle your creamy roasted garlic potato soup into bowls and get creative with your garnishing! Top with freshly grated parmesan cheese, chopped chives, or indulge with some grilled cheese croutons for that extra touch of comfort. Feeling fancy? A drizzle of olive oil can take your presentation over the top. Enjoy your warming bowl of goodness!
For a delightful pairing, consider making some grilled cheese croutons to add a crunchy twist to your creamy soup. Trust me, your friends will be begging you for this recipe!

Vegetarian Adaptations

Cooking Tips and Notes for Roasted Garlic Potato Soup
Ensuring the Perfect Blend
To achieve a velvety texture in your roasted garlic potato soup, use an immersion blender for easy blending right in the pot. If you’re using a traditional blender, blend in batches to avoid spills. If the soup feels too thick, slowly mix in more broth until it reaches your desired consistency.
Adjusting Thickness and Seasoning
Taste is key! Start with the base ingredients and iterate from there. If you find the soup lacks flavor after blending, season with additional salt, pepper, or a pinch of fresh thyme. The beauty of roasted garlic potato soup lies in your ability to customize it to your liking, so don’t hesitate to experiment!
