Roasted Garlic Soup

Featured in: Cozy Slow-Roast Comforts

This roasted garlic soup transforms humble heads of garlic into a luxurious, velvety bowl of comfort. The slow-roasting process mellows the garlic's sharpness, bringing out its natural sweetness and creating a deeply aromatic base.

The soup comes together in just over an hour, with most of that time being hands-off roasting. A simple mirepoix of onion, celery, and carrot adds depth, while heavy cream creates that signature silky texture.

Perfect for cold weather or when you're feeling under the weather, this vegetarian and easily gluten-free soup serves four generously. The roasting step is essential—it's what gives the soup its golden color and complex flavor profile.

Customize with your choice of garnishes: crusty croutons, fresh parsley, or a final drizzle of olive oil. For a vegan version, simply swap butter and cream for olive oil and coconut cream.

Instructions

Step 1: Roast the Garlic
Preheat the oven to 400°F (200°C). Slice the tops off the garlic heads to expose the cloves. Drizzle with a little olive oil, wrap in foil, and roast for 35–40 minutes until the cloves are soft and golden.
Step 2: Prepare the Cloves
Allow the garlic to cool, then squeeze the roasted cloves out of their skins and set aside.
Step 3: Sauté Aromatics
In a large pot, melt the butter over medium heat. Add onion, celery, and carrot, and sauté for 5–7 minutes until softened.
Step 4: Season
Add the roasted garlic, thyme, salt, and pepper. Cook for 2 minutes, stirring.
Step 5: Simmer
Pour in the vegetable broth. Bring to a boil, then reduce heat and simmer for 10 minutes.
Step 6: Purée
Use an immersion blender (or transfer to a countertop blender in batches) to purée the soup until smooth.
Step 7: Finish
Stir in the heavy cream and heat gently for 2–3 minutes. Adjust seasoning if needed.
Step 8: Serve
Serve hot, garnished with chopped parsley, croutons, or a drizzle of olive oil.

Ensure the garlic is roasted until completely soft and golden for the best flavor. If using a countertop blender, be sure to blend in small batches and leave the lid slightly ajar to allow steam to escape safely.

Recipe Questions & Answers

Why roast the garlic first?

Roasting garlic transforms its flavor from sharp and pungent to sweet, mellow, and deeply aromatic. The slow heat caramelizes the natural sugars, creating a rich base that gives this soup its signature depth and golden color.

Can I make this soup vegan?

Absolutely. Replace the butter with olive oil and swap the heavy cream for full-fat coconut cream or cashew cream. The soup will still be velvety and satisfying, just with a slightly different flavor profile.

How do I store leftovers?

Store cooled soup in an airtight container in the refrigerator for up to 4 days. Reheat gently over low heat, adding a splash of broth or cream if needed to thin the consistency. The flavors often develop even more after a day.

Can I freeze this soup?

Yes, but leave out the cream if freezing. Dairy can separate when frozen and reheated. Freeze the puréed broth base, then stir in fresh cream when you reheat it for the best texture.

What can I serve with this soup?

Crusty bread, grilled cheese sandwiches, or a simple green salad make excellent accompaniments. For a lighter meal, serve alongside roasted vegetables. The soup is substantial enough to stand alone as a comforting main.

Is the garlic flavor overpowering?

Not at all. The roasting process completely transforms the garlic, making it mild and sweet rather than pungent. Even those who typically avoid raw garlic often find this soup subtle and approachable.
