Step‑by‑Step Instructions for Roasted Garlic Potato Soup with Grilled Cheese Croutons
Step 1: Prepare the Oven and Garlic
Preheat your oven to 375–400°F (190–200°C) to create a warm environment for roasting. Slice the top off a head of garlic to expose the cloves, drizzle it with olive oil, and season generously with salt and pepper. Wrap the garlic in foil and roast for 40–45 minutes, until soft and fragrant. Once done, allow it to cool, then squeeze the roasted cloves from their skins.
Step 2: Cook the Potatoes
As the garlic roasts, bring a large pot of water to a boil. Add the peeled and cubed russet potatoes, then cook until fork-tender, which should take about 15-20 minutes. Once cooked, carefully drain the potatoes and set them aside to cool slightly. This will ensure they blend smoothly into the soup later.
Step 3: Sauté Onions and Leeks
In a large pot or Dutch oven over medium heat, melt 4 tablespoons of butter. Add the diced onion and leek, and sauté for about 5-7 minutes until they become softened and translucent. This step builds a flavorful base for your Roasted Garlic Potato Soup, releasing all those wonderful aromas.
Step 4: Create the Soup Base
Lower the heat to medium and sprinkle ¼ cup of all-purpose flour over the softened onions and leeks. Stir continuously for about 1 minute until the mixture becomes lightly golden. Next, gradually whisk in 4 cups of vegetable or chicken broth, 1 cup of milk, and ½ cup of heavy cream. Add a teaspoon of dried thyme and season with salt and pepper, heating until slightly thickened.
Step 5: Blend the Soup
To the pot, add the cooked potatoes and the squeezed roasted garlic cloves. Toss in ½ cup of grated Parmesan cheese and blend everything together using an immersion blender until smooth. If your soup is too thick, feel free to add up to 1 cup of additional broth until it reaches your desired consistency. Give it a taste and adjust the seasoning if needed.
Step 6: Make the Grilled Cheese Croutons
While the soup simmers, butter one side of each of the 4 slices of bread. Place 1 cup of grated Gruyère cheese on the non-buttered side of two slices, then top with the other slices, buttered side facing out. In a skillet or panini press, cook the sandwiches until golden brown and the cheese has melted, about 5 minutes per side. Let them cool slightly, then cut into 1-inch croutons.
Step 7: Serve the Soup
Ladle your delightful Roasted Garlic Potato Soup into warm bowls. For an extra touch, garnish each serving with additional grated Parmesan, chopped chives, and those delicious grilled cheese croutons. This will not only enhance the flavor but also add a wonderful crunch alongside the creamy soup.
Make Ahead Options
Busy home cooks will appreciate how easy it is to prepare this Roasted Garlic Potato Soup with Grilled Cheese Croutons in advance! You can make the soup up to 3 days ahead; simply follow the recipe until blending, then let it cool before transferring it to an airtight container and refrigerating. The grilled cheese croutons can also be prepped the day before and stored in a separate container; just make sure they are completely cool to keep their crunch. When you’re ready to enjoy, reheat the soup on the stove (adding a splash of broth if it thickens) and serve with the croutons for a cozy, delicious meal that feels just as good as fresh!

Expert Tips for Roasted Garlic Potato Soup
Texture Matters: Ensure your potatoes are cooked until fork-tender for a creamy Roasted Garlic Potato Soup. Undercooked potatoes can lead to a lumpy texture.
Roasting Garlic: Don’t rush the roasting process; the depth of flavor from properly roasted garlic is essential. Keep it wrapped and let it cool to avoid burnt fingers!
Adjust Consistency: If your soup thickens too much after blending, reintroduce broth gradually until you achieve your desired creaminess.
Cheese Choices: Use a high-quality Gruyère for the croutons for the best meltability and flavor. Cheddar works too, but it will change the taste profile slightly.
Season Gradually: Taste as you go! Seasoning with salt and pepper gradually helps avoid over-salting your Roasted Garlic Potato Soup, leading to a well-balanced flavor.
Roasted Garlic Potato Soup with Grilled Cheese Croutons Recipe FAQs
How do I choose the right garlic for roasting?
Absolutely! Look for a head of garlic that feels firm and heavy, with tight, unblemished skin. Avoid any heads with dark spots or soft areas, as these indicate that the garlic is past its prime and may not roast well.
How should I store my Roasted Garlic Potato Soup?
You can store your leftovers in an airtight container in the fridge for up to 3 days. Make sure the soup has cooled completely before sealing it. This helps maintain its fresh flavors and creamy texture.
Can I freeze Roasted Garlic Potato Soup? What’s the best way?
Yes, you can freeze it! Let the soup cool down first, then transfer it to freezer-safe containers, leaving some space at the top for expansion. It will keep well in the freezer for up to 3 months. To reheat, thaw it in the fridge overnight and warm it over medium heat, stirring occasionally. If it seems thick, add a splash of broth or cream to bring back the silky consistency.
What if my soup is too thick after blending?
No worries at all! If your soup turns out thicker than you like, simply stir in additional broth—up to about 1 cup—until it reaches your desired creaminess. Keep tasting as you go for perfect results!
Are there any dietary considerations I should be aware of?
Great question! This soup contains dairy, so if you have lactose intolerance, you might want to substitute the milk and heavy cream with non-dairy alternatives, like coconut or almond milk. Additionally, always double-check ingredient labels if you're catering to specific allergies.
Can I use a different cheese for the croutons?
Very much! While Gruyère cheese adds a lovely depth and creaminess, feel free to use other cheeses like cheddar or mozzarella. Just keep in mind that altering the cheese may slightly change the flavor of your croutons, but variety is the spice of life!
