Roasted Garlic Potato Soup is a simple, comforting dish made with pantry basics and bold, roasted flavor. It’s hearty without being heavy and perfect for chilly nights when you want something warm and filling without spending hours in the kitchen.

This recipe combines the deep flavor of roasted garlic with the soft, creamy texture of roasted potatoes simmered in a seasoned vegetable broth. You get all the flavor of a slow-cooked soup with minimal hands-on time and just one pot.
Why Garlic Potato Soup Is the Best Soup
1. Bold, Comforting Flavor
Roasted garlic brings deep, mellow flavor without bitterness. When blended into a potato base, it turns a simple soup into something rich and satisfying.
2. Budget-Friendly Ingredients
You only need a handful of pantry staples: potatoes, garlic, onion, broth, and oil. No fancy ingredients, but the flavor payoff is big.
3. Naturally Creamy Without Cream
Thanks to the starch in roasted potatoes, the soup thickens naturally. You get a creamy texture without needing dairy — great for anyone avoiding it.
4. Easy to Customize
Top it with croutons, cheese, parsley, or even roasted chickpeas. Add more broth to thin it or mash extra potatoes for a thicker consistency.
Ingredients You’ll Need
- 4 large potatoes, peeled and cut into large chunks
- 1 small onion, diced
- 4 garlic cloves, minced
- 1 large head of roasted garlic (about 8–10 cloves)
- 2 tablespoons extra virgin olive oil
- 4 cups vegetable broth
- 1 tablespoon fresh parsley, chopped
- 1 teaspoon salt, divided
- ¼ teaspoon freshly ground black pepper
Tip: Use russet or Yukon gold potatoes for the best texture. They break down nicely and help thicken the soup without cream.

How to Make the Perfect Roasted Garlic Potato Soup
Step 1: Sauté the aromatics
In a large soup pot, heat the olive oil over medium heat. Add the diced onion and cook until softened, about 8 minutes. Stir in the minced garlic and ½ teaspoon of salt. Cook for 1 more minute, just until fragrant.
Step 2: Add broth and potatoes
Pour in the vegetable broth and bring to a boil. Add the potato chunks, remaining salt, pepper, and parsley. Reduce heat to a simmer and cook until the potatoes are fork-tender — about 15 to 20 minutes.
Step 3: Add the roasted garlic
Stir in the roasted garlic cloves. You can leave them whole for pockets of flavor or lightly mash them with a fork before adding for a more blended garlic taste.
Step 4: Thicken the soup
For a chunkier texture: Remove 1 cup of potatoes from the pot, mash with a fork, then return to the soup.
For a smoother texture: Use an immersion blender to partially blend the soup right in the pot until it reaches your desired consistency.
Step 5: Serve and garnish
Ladle into bowls and top with extra parsley, croutons, or a sprinkle of cheese if you like. Serve warm.

Frequently Asked Questions
Can I use regular garlic instead of roasted garlic?
Yes, but the flavor will be stronger and sharper. Roasted garlic adds a milder, slightly sweet depth that works better in this soup. If you use raw garlic, sauté it well to mellow it out.
How do I roast a head of garlic?
Slice off the top of a whole garlic head, drizzle with olive oil, wrap in foil, and roast at 400°F for 35–40 minutes. The cloves will be soft and caramelized, perfect for soups and spreads.
What kind of potatoes work best?
Russet or Yukon gold potatoes are ideal. They break down easily when simmered, which helps thicken the soup naturally.
Can I make this soup ahead of time?
Yes. It stores well in the fridge for up to 4 days. Reheat on the stove over medium heat, adding a splash of broth or water if it thickens too much.
