Ingredients You’ll Need
Roasted Garlic
- 3 whole heads garlic, outer papery skins removed, tops sliced off
- 2 tablespoons olive oil
- Pinch of kosher salt
- Pinch of black pepper
Soup Base
- 2 tablespoons unsalted butter
- Use olive oil instead if you want a dairy free version.
- 1 tablespoon olive oil
- I like California or Spanish extra virgin for a fruity flavor.
- 1 large yellow onion, diced
- 2 medium leeks, white and light green parts only, sliced and rinsed
- If you do not have leeks, use 1 extra onion.
- 2 medium Yukon Gold potatoes, peeled and diced small
- Russet potatoes work, but Yukon Gold gives a creamier texture.
- 1 medium carrot, diced
- This adds natural sweetness and color.
- 5 cups low sodium chicken broth or vegetable broth
- I often use Better Than Bouillon roasted chicken base for a pantry shortcut.
- 1 cup whole milk or half and half
- 1 bay leaf
- 1 teaspoon fresh thyme leaves or 1/2 teaspoon dried thyme
- 1/2 teaspoon smoked paprika
- Use sweet paprika if you prefer a milder flavor.
- 1/4 teaspoon ground white pepper
- Black pepper works fine; white just keeps the color pale.
- 1 teaspoon kosher salt, plus more to taste
Optional Flavor Boosters
- 1/4 cup grated Parmesan cheese
- I prefer a wedge that I grate myself; pre-grated often tastes dry.
- Squeeze of fresh lemon juice, to brighten at the end
- Pinch of red pepper flakes, for gentle heat
Toppings
- Garlic croutons or toasted baguette slices
- Extra grated Parmesan or shredded mozzarella
- Drizzle of good olive oil
- Chopped fresh parsley or chives
Equipment
- Baking sheet lined with foil
- Large stock pot or Dutch oven
- Sharp chef’s knife and cutting board
- Blender or immersion blender
- I like an immersion blender for easier cleanup.
- Ladle and heatproof spatula
Tips & Tricks
- Roast the garlic until it feels very soft and smells sweet, not sharp, usually 35 to 40 minutes.
- Let the roasted garlic cool enough to handle, then squeeze from the base so the cloves slide out easily.
- Slice the potatoes small and evenly so they cook at the same rate and blend smoothly.
- Keep the heat at medium when you sauté the onions and leeks so they soften and turn sweet without burning.
- Use low sodium broth so you control the salt level and adjust at the end.
- Blend the soup very smooth for a restaurant style texture, or pulse a few times if you like a bit of texture.
- Stir in dairy off the heat so it stays silky and does not curdle.
- Taste before serving and adjust with salt, pepper, and a small squeeze of lemon juice to brighten the flavor.
- Make extra roasted garlic while you cook and save it for mashed potatoes, spreads, or salad dressings.
- If the soup feels too thick, thin it with warm broth or water a little at a time.
How to Make Roasted Garlic Soup
Step 1: Roast the Garlic
Heat your oven to 400°F. Place the garlic heads on a piece of foil, drizzle with olive oil, and sprinkle with salt and pepper. Wrap tightly, set on a baking sheet, and roast for 35 to 40 minutes, until the cloves feel very soft and smell sweet. Set aside to cool while you start the soup.
Step 2: Sauté Veggies and Aromatics
Heat butter and olive oil in a large stock pot over medium heat. Add the onion, leeks, carrot, and a pinch of salt, then cook until very soft and lightly golden, about 8 to 10 minutes, while you stir occasionally. Add the potatoes, thyme, smoked paprika, and white pepper, then cook 2 to 3 minutes so the spices bloom and coat the vegetables.
Step 3: Add Broth and Simmer
Pour in the broth and stir, scraping up any browned bits from the bottom of the pot. Add the bay leaf and bring the mixture to a gentle boil, then lower to a steady simmer. Cook for 15 to 20 minutes, until the potatoes feel very tender when you pierce them with a fork.
Step 4: Add Roasted Garlic
Squeeze the cooled roasted garlic cloves out of their skins directly into the pot. Stir well so the garlic breaks up and blends with the vegetables. Simmer 5 more minutes so the roasted garlic flavor infuses the broth.
Step 5: Blend Until Velvety
Remove the bay leaf. Use an immersion blender to purée the soup until it turns very smooth and creamy, or transfer in batches to a blender and blend carefully with the lid vented and a towel on top. If the soup looks thicker than you like, add a splash of warm broth or water and blend again.
Step 6: Finish with Creaminess and Seasoning
Lower the heat to low and stir in the milk or half and half, along with Parmesan if you use it. Heat gently until the soup feels hot and steamy, but do not let it boil. Taste and adjust with more salt, pepper, and a small squeeze of lemon juice if you want a brighter flavor.
Step 7: Garnish
Ladle the Tasty Roasted Garlic Soup Recipe into warm bowls. Top with garlic croutons or toasted baguette slices, a sprinkle of herbs, and a drizzle of olive oil. Serve right away while it steams and makes your kitchen smell like a cozy bistro.
What to Serve with Roasted Garlic Soup
This Tasty Roasted Garlic Soup Recipe pairs beautifully with a crisp green salad loaded with cucumbers, tomatoes, and a simple vinaigrette. Add warm crusty bread, garlic breadsticks, or cheesy toast for dipping and you have a complete meal. For a heartier spread, serve it alongside grilled chicken, roasted vegetables, or a simple pasta with olive oil and herbs. A tall glass of iced tea, sparkling water with lemon, or a light fruit smoothie rounds out the meal nicely.
Storage Options
- Cool the soup to room temperature, then store it in airtight containers in the fridge for up to 4 days.
- For freezing, portion the soup into freezer safe containers, leave a little space at the top, and freeze for up to 3 months.
- Thaw frozen soup overnight in the fridge or in a bowl of cold water, then reheat gently in a pot over medium low heat, while you stir often.
- If the soup thickens in the fridge or freezer, whisk in a splash of broth or water while you reheat until it reaches your preferred texture.

Ingredients
Instructions
- Preheat the oven to 400°F (200°C).
- Cut the tops off the heads of garlic to expose the cloves. Place each head on a piece of foil, drizzle with 1 tablespoon of olive oil divided among them, and wrap tightly. Roast for 30–35 minutes, or until the cloves are very soft and golden. Let cool slightly, then squeeze the roasted garlic cloves from their skins into a small bowl and mash lightly.
- In a large pot over medium heat, melt the butter with the remaining 1 tablespoon of olive oil. Add the chopped onion and leek (if using) and cook, stirring often, until softened and translucent, about 6–8 minutes.
- Stir in the mashed roasted garlic and thyme, and cook for 1–2 minutes until fragrant.
- Pour in the broth, bring to a simmer, then reduce the heat to low and cook gently for 10–15 minutes to let the flavors meld.
- Using an immersion blender, blend the soup until completely smooth. Alternatively, carefully transfer the soup in batches to a countertop blender and puree, then return it to the pot.
- Stir in the heavy cream and nutmeg (if using). Season with salt and black pepper to taste, and warm gently over low heat without boiling for 3–5 minutes.
- Ladle the roasted garlic soup into bowls. Top with grated Parmesan and serve with toasted crusty bread if desired.
