Step‑by‑Step Instructions for Roasted Garlic Potato Soup with Grilled Cheese Croutons
Step 1: Roast the Garlic
Preheat your oven to 375–400°F (190–200°C). Slice the top off a head of garlic to reveal the cloves, drizzle with olive oil, and season with salt and pepper. Wrap the garlic in foil and roast for 40–45 minutes, until soft and fragrant. Once done, let it cool, then squeeze out the roasted cloves into a bowl, setting the aromatic base for your Roasted Garlic Potato Soup.
Step 2: Prepare the Potatoes
While the garlic roasts, bring a large pot of water to a boil. Add 2 pounds of russet potatoes, cooking them until fork-tender, which should take about 15–20 minutes. Once cooked, drain the potatoes and allow them to cool slightly. Set them aside as they will blend beautifully into the creamy texture of the soup.
Step 3: Sauté the Aromatics
In a large pot or Dutch oven over medium heat, melt 4 tablespoons of butter. Add 1 cup of chopped onions and 1 cup of sliced leeks, sautéing until they become soft and translucent, which will take about 5–7 minutes. This step layers in flavors that will deepen the taste of your Roasted Garlic Potato Soup.
Step 4: Make the Base
Lower the heat to medium and stir in ¼ cup of all-purpose flour, cooking for about 1 minute until it’s lightly golden. Gradually whisk in 4 cups of vegetable or chicken broth, 1 cup of milk, and ½ cup of cream, along with 1 teaspoon of fresh thyme. Allow the mixture to heat until it thickens slightly, creating a rich and luxurious soup base.
Step 5: Puree the Soup
Add the reserved cooked potatoes and the roasted garlic cloves to the pot. Stir in ½ cup of grated Parmesan cheese for added depth. Use an immersion blender to purée the soup until it's completely smooth. If the soup is too thick for your liking, gradually add up to 1 cup of more broth until it reaches your desired consistency, then adjust the seasonings with salt and pepper.
Step 6: Prepare the Grilled Cheese Croutons
While the soup simmers, butter one side of each of the 4 slices of bread. On the unbuttered side of two slices, layer 1 cup of grated Gruyère cheese, and then top them with the remaining slices, creating a sandwich with the buttered sides out. Cook in a skillet over medium heat until golden brown and the cheese melts, about 5 minutes per side. Once cooked, cut into 1-inch croutons.
Step 7: Serve and Garnish
Ladle your wonderful Roasted Garlic Potato Soup into bowls, and elevate it with additional grated Parmesan, chopped chives, and the crispy grilled cheese croutons on top. This creates a beautiful presentation that adds texture and flavor to your meal, perfect for sharing with family and friends.
