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 the head of garlic to reveal the cloves, drizzle it with olive oil, and season generously with salt and pepper. Wrap the garlic in aluminum foil and place it in the oven for 40–45 minutes, until the cloves are soft and golden.

Step 2: Cook the Potatoes
While the garlic roasts, bring a large pot of water to a boil. Add the peeled and diced russet potatoes, cooking them for about 15–20 minutes until they are fork-tender. Once cooked, drain the potatoes, allow them to cool slightly, and set them aside for later use in your Roasted Garlic Potato Soup.

Step 3: Sauté the Aromatics
In a large pot or Dutch oven over medium heat, melt the butter until it’s bubbly. Add the diced onions and sliced leeks, stirring occasionally for about 5–7 minutes until they become softened and translucent. This fragrant base is crucial for building flavor in your soup.

Step 4: Create the Soup Base
Lower the heat to medium and stir in the flour, cooking for approximately 1 minute until it turns lightly golden. Gradually whisk in the broth, milk, cream, and thyme, seasoning with salt and pepper as you go. Heat the mixture gently until it’s well-combined and slightly thickened, laying the foundation for your creamy soup.

Step 5: Blend in the Potatoes and Garlic
Now, add the cooked potatoes and the roasted garlic cloves, squeezing them from their skins directly into the pot. Stir in the grated Parmesan cheese, which will melt into the soup, enriching its flavor. Allow everything to bubble together for a couple of minutes to meld the flavors beautifully.

Step 6: Purée the Soup
Using an immersion blender, purée the soup until smooth and creamy. If the consistency is too thick for your liking, feel free to stir in more broth until you achieve your desired texture. Taste and adjust the seasoning with additional salt and pepper if needed, ensuring that your Roasted Garlic Potato Soup is perfectly seasoned.

Step 7: Prepare the Grilled Cheese Croutons
While the soup simmers, butter one side of each slice of bread. On the unbuttered side of two slices, generously pile the shredded Gruyère cheese, then top with the other slices, buttered side out. Heat a skillet over medium heat and cook the sandwiches for about 5 minutes on each side, until they're golden brown and the cheese is melted.

Step 8: Slice and Serve
Once the grilled cheese sandwiches are done, remove them from the skillet and cut them into 1-inch croutons. Ladle your rich and creamy Roasted Garlic Potato Soup into bowls, garnishing with additional Parmesan cheese, freshly chopped chives, and a generous handful of grilled cheese croutons for that nostalgic touch before serving.

Make Ahead Options

These Roasted Garlic Potato Soup with Grilled Cheese Croutons are perfect for busy weeknights! You can prepare the soup base (steps 1 to 6) up to 3 days in advance and store it in an airtight container in the refrigerator. The grilled cheese croutons can also be made ahead; simply cook them, cool completely, and keep them in a sealed container for up to 24 hours. When you're ready to serve, gently reheat the soup on the stovetop, adding a splash of broth if needed to adjust the consistency before blending. Finish by garnishing with freshly made croutons and chives for a meal that’s just as delicious as when first prepared!

Roasted Garlic Potato Soup with Grilled Cheese Croutons Recipe FAQs

How do I choose the right garlic for roasting?
Absolutely! When selecting garlic, look for heads that are firm and free from dark spots or soft areas. A fresh head of garlic will have tight, unbroken skin and should feel heavy for its size. This ensures you're getting the best flavor to elevate your Roasted Garlic Potato Soup with Grilled Cheese Croutons.

How long can I store the soup in the refrigerator?
You can store leftover Roasted Garlic Potato Soup in an airtight container in the fridge for up to 3 days. When you're ready to enjoy it again, simply reheat it gently on the stovetop or microwave, adding a splash of broth or milk if it has thickened too much during storage.

Can I freeze this soup?
Yes, you can freeze the soup for up to 2 months! To do this, allow the soup to cool completely and then portion it into airtight containers or freezer bags. Remember to leave some space for expansion during freezing. When you're ready to enjoy it, thaw it in the fridge overnight. Reheat on the stovetop, adding a splash of milk or cream for a creamy texture.

What can I do if the soup is too thick after blending?
If you find your Roasted Garlic Potato Soup is thicker than you'd like, no worries! Just add a bit more broth or milk gradually while stirring until you reach your preferred consistency. Taste and adjust the seasoning with a little salt and pepper if necessary. This way, you’ll ensure that each bowl is just right!

Are there any dietary considerations for this soup?
Of course! If you're cooking for someone with dietary restrictions, you can easily adapt this recipe. To make it dairy-free, substitute the milk and cream with your favorite plant-based alternatives, such as almond milk or coconut cream. For those with gluten allergies, replace the flour with a gluten-free thickener, like cornstarch or arrowroot powder, mixed with some broth. This way, everyone can enjoy this cozy soup!

How should I store the grilled cheese croutons?
Your grilled cheese croutons are best enjoyed fresh, but if you have leftovers, store them in an airtight container at room temperature for up to 2 days. This helps maintain their crispiness!
