Preparing Roasted Garlic Potato Soup
Making a Roasted Garlic Potato Soup is a delightful journey filled with aromatic flavors and simple steps. Here's how to prepare this creamy soup that warms the soul!
Start by Roasting the Garlic
The heart of our soup truly begins with roasting the garlic. Preheat your oven to 375ºF and slice off the top of a whole head of garlic to expose the cloves. Drizzle it with a teaspoon of olive oil and sprinkle a little salt and pepper over it. Wrap the garlic in foil and place it on a baking sheet. Let it roast for about 40-45 minutes, or until it’s tender. Once it cools, you’ll be able to squeeze out that sweet, caramelized garlic goodness—perfect for enhancing the soup's flavor!

Get Those Potatoes Ready
While the garlic is roasting, you can prepare the potatoes. Peel about 1¾ pounds of russet potatoes and cut them into uniform chunks. Boil them in a large pot of salted water until tender, which should take around 15 minutes. Once they are soft, drain and set them aside. Cubing your potatoes helps them mash easier later, ensuring a smooth consistency in your soup.
Sauté the Aromatics for Depth
In a large Dutch oven over medium-high heat, melt 4 tablespoons of salted butter. Add 1 cup of chopped white onions and 1 cleaned leek (thinly sliced). Sauté these for about 6-8 minutes until they soften and turn translucent. This step is crucial as the onions and leeks will create a flavor base that really elevates your roasted garlic potato soup.
Combine the Ingredients to Make the Soup
Reduce the heat to medium and add 3 tablespoons of flour to absorb the excess fats. Cook for about 1 to 1.5 minutes to create a roux that thickens the soup. Gradually stir in 4 cups of low-sodium chicken broth (or vegetable broth if you prefer), followed by 1 cup of whole milk, ¼ cup of heavy cream, ½ teaspoon of fresh thyme, and season with salt and pepper to taste. Bring this mixture to a boil, then simmer for 2-3 minutes until it starts to thicken. Now, fold in your boiled potatoes and the syrupy roasted garlic, plus ½ cup of grated parmesan cheese for an extra layer of creaminess.
Blend Until Smooth
Using an immersion blender, blend the soup until it’s fabulously smooth. If you don’t have one, a traditional blender works well too—just be careful to let it cool slightly and blend in batches. If you prefer a thinner consistency, feel free to add more broth as needed! Tasting and adjusting your seasonings at this stage is crucial for achieving that perfect flavor balance.
Serve with Toppings for a Delicious Finish
Finally, ladle the soup into bowls and adorn it with your favorite toppings. Freshly grated parmesan, chopped chives, or those delightful grilled cheese croutons will take your roasted garlic potato soup to the next level. For an easy grilled cheese recipe, check out this grilled cheese tutorial.
Enjoy this comforting dish on a chilly day or any time you crave a bowl of warmth!

Variations on Roasted Garlic Potato Soup
Extra Garlicky Version
If you’re a garlic aficionado, consider doubling the roasted garlic in your roasted garlic potato soup. This enhancement will amplify the natural sweetness and create a more robust flavor profile. For an even bolder experience, you might even experiment with adding a splash of lemon juice or a sprinkle of smoked paprika to elevate the dish further. Just imagine the delightful aroma filling your kitchen!
Vegan Adaptation
Looking for a plant-based twist? Transform this roasted garlic potato soup by swapping out the dairy ingredients for coconut milk or almond milk and using vegan butter instead of the traditional butter. You can enrich the flavors with nutritional yeast for that cheesy taste. This vegan version will still give you a deliciously creamy soup that everyone can appreciate!
