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 expose the cloves, drizzle with olive oil, and season with salt and pepper. Wrap it in foil and roast for 40–45 minutes, or until soft and fragrant. Allow it to cool, then squeeze out the tender roasted garlic from their skins.
Step 2: Cook the Potatoes
In a large pot, bring water to a boil. Add the Russet potatoes and cook until fork-tender, which should take about 15–20 minutes. Once cooked, drain and let them cool slightly before setting them aside. When ready, they will blend seamlessly into your Roasted Garlic Potato Soup.
Step 3: Sauté the Onions and Leeks
In a large pot or Dutch oven over medium heat, melt the butter until it’s bubbly. Add the chopped onions and leeks, sautéing for about 5–7 minutes until they soften and become translucent. Enjoy the aromatic blend filling your kitchen as you prepare the base for your comforting soup.
Step 4: Create the Soup Base
Lower the heat to medium and stir in the flour, cooking it for about 1 minute until it turns lightly golden. Gradually whisk in the broth, milk, cream, and thyme, seasoning with salt and pepper. Continue heating until the mixture begins to thicken slightly, creating a rich, flavorful base for your Roasted Garlic Potato Soup.
Step 5: Blend in the Main Ingredients
Add the cooked potatoes and roasted garlic cloves to the pot, followed by the grated Parmesan cheese. Use an immersion blender to purée the soup until it’s perfectly smooth. If it’s too thick, slowly add broth, up to 1 cup, until you achieve your desired consistency, then taste and adjust seasoning as necessary.
Step 6: Prepare the Grilled Cheese Croutons
Butter one side of each bread slice. On the non-buttered side of two slices, layer the Gruyère cheese, then top with the remaining bread slices (buttered side facing out). Cook in a skillet or panini press over medium heat for about 5 minutes per side, or until golden brown and melty. After cooking, let them cool briefly and cut into 1-inch croutons.
Step 7: Serve and Garnish
Ladle the warm Roasted Garlic Potato Soup into bowls. Before serving, garnish each bowl with additional Parmesan cheese and chopped chives for a pop of freshness. Finally, top the soup with the grilled cheese croutons, adding a delightful twist that elevates your meal.

Helpful Tricks for Roasted Garlic Potato Soup
Perfect Consistency: Use an immersion blender: Blending the soup thoroughly will ensure a luxuriously smooth texture; if it’s too thick, don’t hesitate to add more broth.
Flavor Boost: Season as you go: Tasting and adjusting the seasoning at each stage enhances the overall flavor of your Roasted Garlic Potato Soup.
Quick Cheese Melt: Grill with care: Make sure your skillet is adequately heated to toast the bread while melting the Gruyère cheese evenly for the croutons.
Garlic Magic: Roast to perfection: Keep an eye on the garlic while roasting; it should be soft and fragrant but not burnt, as burnt garlic can turn bitter.
Make-Ahead Option: Soup storage: This soup can be prepared in advance and kept in the fridge for up to three days; just reheat gently before serving with croutons!
How to Store and Freeze Roasted Garlic Potato Soup
Fridge: Store your Roasted Garlic Potato Soup in an airtight container for up to 3 days. Allow it to cool completely before sealing to maintain freshness.
Freezer: This delightful soup freezes well! Transfer cooled soup to freezer-safe containers or bags. It can be frozen for up to 3 months.
Reheating: Thaw overnight in the fridge before gently reheating on the stove or in the microwave. If the soup has thickened, stir in a little broth to reach your desired consistency.
Grilled Cheese Croutons: For optimal texture, prepare croutons fresh when serving. If you have leftovers, store them in a separate container at room temperature for up to 1 day.

These Roasted Garlic Potato Soup with Grilled Cheese Croutons are perfect for meal prep enthusiasts! You can prepare the soup base up to 3 days in advance by following the initial steps—roasting the garlic, cooking the potatoes, and making the soup mixture.

For the grilled cheese croutons, you can assemble them and refrigerate before cooking; this will help maintain their texture. When you’re ready to serve, gently reheat the soup on the stove (adding broth if needed for consistency), and fry the croutons until golden brown. This way, you’ll enjoy a comforting meal with minimal effort, just as delicious as when made fresh!

Roasted Garlic Potato Soup with Grilled Cheese Croutons Recipe FAQs
How do I choose the right garlic for roasting?
When selecting garlic for your Roasted Garlic Potato Soup, look for bulbs that are firm and free of dark spots or sprouting. Choose heads that feel heavy in your hand, as they will have more cloves and robust flavor. Freshness is key, so check that the garlic skin is dry and tight around the bulb.
What is the best way to store leftovers?
Store your Roasted Garlic Potato Soup in an airtight container in the fridge for up to 3 days. Allow the soup to cool completely before sealing to maintain the best flavor and texture. If you notice any separation, give it a gentle stir before reheating – a quick fix for that creamy goodness.
Can I freeze Roasted Garlic Potato Soup?
Absolutely! This soup freezes wonderfully. Transfer cooled soup into freezer-safe containers or bags, leaving a little space at the top for expansion. It can be frozen for up to 3 months. When you're ready to enjoy it again, thaw overnight in the fridge and gently reheat, adding broth if it’s too thick.
What if my soup is too thick after blending?
If your Roasted Garlic Potato Soup ends up thicker than you'd like, no worries! Simply stir in broth, a little at a time, until you reach your desired consistency. Begin with ¼ cup and go from there. Mixing it well while reheating helps everything come together nicely.
Are there any dietary considerations I should keep in mind?

Just ensure your broth is also dairy-free. Always double-check your labels for allergens when preparing this comforting dish.
How do I know if my potatoes are fresh?
Fresh Russet potatoes should be firm and free from blemishes or dark spots. If they have sprouted a bit, don’t worry too much; just remove the sprouts before cooking. Potatoes should be stored in a cool, dark place and used within a few weeks for the best flavor in your Roasted Garlic Potato Soup!
