Step-by-Step Preparation for Roasted Garlic Potato Soup
Creating a comforting bowl of roasted garlic potato soup is a delightful experience that warms the soul. Here’s a step-by-step guide to help you craft this creamy, savory dish with ease.
Roasting the garlic to perfection
Start by preheating your oven to 375ºF. Slice off the top of the head of garlic to expose the cloves, then drizzle it with about a teaspoon of olive oil and a sprinkle of salt and pepper. Wrap the garlic head in foil and place it on a baking sheet. Roast for 40-45 minutes until it’s tender and fragrant. The sweetness of roasted garlic can’t be overstated—it transforms the flavor profile of your soup!
Boiling the potatoes for a smooth base
While your garlic is roasting, fill a large pot with water and bring it to a boil. Peel and cube about 1¾ pounds of russet potatoes (don't worry if they don’t look perfect!). Add them to the boiling water and cook for approximately 15 minutes, or until they are fork-tender. Once done, drain and allow them to cool slightly. This tender potato base will ensure a luxuriously creamy soup.
Sautéing the onions and leeks for flavor depth
In a large Dutch oven, melt four tablespoons of salted butter over medium-high heat. Add one cup of chopped onions and one cleaned, thinly sliced leek (use only the whites and pale greens for a mild flavor). Sauté these aromatics for about 6-8 minutes until they soften and turn translucent. The combination of onions and leeks adds layers of flavor that elevate your roasted garlic potato soup to new heights.
Creating the soup blend of flavors
Lower the heat to medium, and add three tablespoons of flour to the onion-leek mixture. Cook for about 60-90 seconds, until the flour is lightly golden. Then, pour in 4 cups of low-sodium chicken broth (or vegetable broth, if preferred), along with one cup of whole milk and ¼ cup of heavy cream. Add in ½ teaspoon of fresh thyme (or ¼ teaspoon of dried) with a pinch of salt and pepper. Bring this to a gentle boil before letting it simmer for 2-3 minutes—this helps the flavors meld beautifully before introducing the potatoes and roasted garlic.
Blending for that velvety finish
Once the soup has thickened slightly, it’s time to blend. You can use an immersion blender to achieve that silky consistency right in the pot. If you don’t have one, carefully transfer the soup to a traditional blender in batches. If the soup seems too thick for your liking, adjust it with more chicken broth, up to a cup if needed. Taste it—this is your chance to tweak the seasonings for a perfect balance!
Serving and garnishing the soup
When your roasted garlic potato soup is ready, serve it hot in bowls. Top generously with freshly grated parmesan cheese, chopped chives, or those irresistible grilled cheese croutons (which you can learn to make here). Not only do these add texture, but they also bring a delightful cheesy flavor that complements the creamy soup beautifully.
With this step-by-step guide, you’re set to impress at any dinner table. Happy cooking!

Variations on Roasted Garlic Potato Soup
Extra Garlicky Variation
If you're a die-hard garlic lover, consider adding a second head of roasted garlic to your soup! Doubling up enhances the sweet, caramelized notes and provides an richer base flavor.

Cooking Tips and Notes for Roasted Garlic Potato Soup
Adjustments for Thickness
To customize the thickness of your roasted garlic potato soup, start by blending it to your desired consistency.

Remember, you can always add more, but it’s difficult to fix it if you’ve made it too thin!
Enhancements for Flavor
For an extra flavor boost, consider doubling the roasted garlic for a sweeter, more robust taste.
