Step‑by‑Step Instructions for Roasted Garlic Potato Soup with Grilled Cheese Croutons
Step 1: Preheat and Roast Garlic
Begin by preheating your oven to 375–400 °F (190–200 °C). Slice the top off the head of garlic, then drizzle it with olive oil and season with salt and pepper. Wrap the garlic snugly in foil and place it in the oven to roast for 40–45 minutes, until it’s soft and fragrant, making your kitchen smell divine.
Step 2: Boil Potatoes
While the garlic roasts, peel and chop the four large russet potatoes into even cubes. In a large pot, bring water to a boil, adding the potatoes once bubbling. Cook them until fork-tender, which should take about 15-20 minutes. Once done, drain them, let them cool slightly, then set aside.
Step 3: Sauté Onions and Leeks
In a large pot or Dutch oven set over medium heat, melt four tablespoons of butter. Add diced medium onion and sliced leek to the pot, stirring occasionally for about 5-7 minutes until softened and translucent. This creates the aromatic base for your Roasted Garlic Potato Soup.
Step 4: Thicken the Soup Base
Once the onions and leeks are ready, lower the heat to medium and stir in ¼ cup of all-purpose flour. Cook the mixture for about 1 minute, allowing it to turn lightly golden. This flour will help thicken your soup, making it luxuriously creamy.
Step 5: Add Liquid Ingredients
Gradually whisk in the 4 cups of chicken or vegetable broth, followed by 1 cup of milk and ½ cup of heavy cream. Stir in 1 teaspoon of dried thyme and season with salt and pepper. Heat this mixture on medium until it slightly thickens, about 5-7 minutes, to form a rich, flavorful soup base.
Step 6: Blend and Incorporate Potatoes
Add the cooked potatoes and the squeezed roasted garlic cloves to the soup base. Using an immersion blender, blend until smooth and creamy. If you don’t have an immersion blender, you can carefully transfer the soup to a blender in batches. This step creates the velvety texture of your Roasted Garlic Potato Soup.
Step 7: Adjust Consistency and Seasoning
If your soup is thicker than desired, feel free to add up to 1 cup of additional broth until you reach your preferred consistency. Taste and adjust the seasoning with extra salt and pepper as needed. Your soup should be rich and flavorful, ready to be served.
Step 8: Prepare Grilled Cheese Croutons
While the soup simmers, butter one side of each slice of bread. On the non-buttered side of two slices, layer the Gruyère cheese generously, then top with the other slices (buttered side out). Cook the sandwiches in a skillet or panini press for about 5 minutes per side, or until golden brown and the cheese melts beautifully.
Step 9: Cut and Serve Croutons
Once the grilled cheese sandwiches are perfectly toasted, let them cool briefly, then cut them into 1-inch croutons. This adds a delightful crunch to your comforting Roasted Garlic Potato Soup and elevates the entire dish.
Step 10: Garnish and Enjoy
Ladle the creamy soup into bowls, garnishing with a sprinkle of additional Parmesan cheese and chopped chives for a burst of color. Top each bowl with the grilled cheese croutons you've prepared. Dive in and enjoy the luscious flavors of your homemade Roasted Garlic Potato Soup with Grilled Cheese Croutons!
How to Store and Freeze Roasted Garlic Potato Soup
Fridge: Store leftover Roasted Garlic Potato Soup in an airtight container for up to 3 days. Reheat on the stove over low heat, adding a splash of milk or broth to adjust the consistency.
Freezer: For longer storage, freeze the soup in freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating. Avoid freezing the grilled cheese croutons, as they may lose their crispness.
Reheating: When ready to eat, gently reheat the soup on the stovetop, stirring occasionally, until hot. If too thick, simply add a bit of broth or milk. Enjoy with freshly made croutons for the best experience!
Cooling Before Storing: Let the soup cool completely before transferring to containers to prevent condensation and maintain its creamy texture.
Make Ahead Options
These Roasted Garlic Potato Soup with Grilled Cheese Croutons are perfect for busy home cooks!

The grilled cheese croutons can also be made ahead—just store them in a separate container and reheat briefly in a skillet to crisp them up before adding them to your soup. Enjoy a comforting meal with minimal effort any night of the week!

Expert Tips for Roasted Garlic Potato Soup
Perfectly Roast Garlic: Ensure you cut off just the top of the garlic head—this allows the cloves to caramelize evenly, enhancing flavor in your Roasted Garlic Potato Soup.
Don't Overcook Potatoes: Fork-tender is the key! Overcooked potatoes can break apart, making your soup gritty instead of smooth.
Blend Smartly: If using a regular blender, allow the soup to cool slightly before blending in batches; this prevents hot soup from splattering.
Adjust Your Broth: If the soup is too thick after blending, add broth gradually until your desired creaminess is reached. Taste test for seasoning before serving.
Crouton Creativity: Experiment with different cheeses for your croutons! Fontina or cheddar can add a unique twist to your grilled cheese topping.
Garnish for Style: A sprinkle of extra Parmesan and fresh chives not only looks beautiful but also adds final touches of flavor that enhance the dish.
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 has dry, tight skin. Avoid any that have soft spots or dark discolorations, as these may indicate spoilage. When you roast it, the flavor transforms, creating a sweet, caramelized delight!
What is the best way to store leftovers of Roasted Garlic Potato Soup?
Very! If you have any leftover soup, store it in an airtight container in the refrigerator for up to 3 days. For reheating, warm it on the stovetop over low heat, adding a splash of milk or broth if the soup thickens too much. This ensures it remains creamy and delicious!
Can I freeze Roasted Garlic Potato Soup?
Yes, you can! To freeze, let the soup cool completely, then pour it into freezer-safe containers, leaving some space at the top for expansion. It will maintain its best quality for up to 3 months. When ready to enjoy, simply thaw it overnight in the fridge and reheat on the stove, stirring occasionally.
What should I do if my soup is too thick?
No worries! If your soup turns out thicker than desired, add broth or milk gradually—up to 1 cup—until you reach the desired consistency. Just reheat it gently on the stovetop while stirring, and remember to taste test before serving!
Are there any dietary considerations for this dish?
Definitely! Since this soup contains dairy, if you’re serving someone with lactose intolerance, you can substitute the milk and heavy cream for lactose-free versions or non-dairy alternatives like almond milk or coconut cream. Just make sure to adjust your seasonings accordingly.
Can I make the grilled cheese croutons ahead of time?
Of course! While these croutons are best enjoyed fresh, you can prepare them in advance. Simply store them in an airtight container at room temperature for a day or two. If you want them to be crispy again, quickly toast them in a skillet just before serving the soup. Enjoy!
