Mouthwatering Potato Garlic Soup

There’s something about garlic that makes everything better. I used to be scared of using too much, but then I realized that roasted garlic gets sweet and mellow instead of sharp. Now I’m the person who doubles the garlic in recipes without even thinking twice.

This potato garlic soup is what I make when I want something warm and filling but don’t feel like babysitting a pot all day. It’s mostly hands-off cooking once you’ve done the chopping. You just throw everything in, let it simmer, and your house smells like you’ve been working hard in the kitchen for hours.

The best part? It uses two whole bulbs of garlic, and nobody will complain that it’s too strong. The potatoes balance everything out and make it creamy without needing any heavy cream. It’s the kind of soup that feels like a hug in a bowl.

What Kind of Potatoes Should I Use?

Yellow potatoes are perfect for this soup because they have a naturally buttery flavor and creamy texture that makes the soup feel rich without adding extra cream. Yukon Gold potatoes are the most common yellow variety you’ll find at the store, and they work great here. If you can’t find yellow potatoes, russet potatoes will also work, though they’ll give you a slightly fluffier, less creamy texture. Red potatoes are another option, but they tend to hold their shape more, so your soup might be a bit chunkier rather than smooth and velvety.

Options for Substitutions

This soup is pretty forgiving when it comes to swapping ingredients:

• Yellow potatoes: Yukon golds are ideal for their creamy texture, but russet or red potatoes work too. Keep in mind that russets will give you a thicker, more starchy soup, while reds will hold their shape better.
• Leek: If you don’t have a leek on hand, just use an extra half onion instead. You’ll lose a bit of that mild, sweet flavor, but the soup will still taste great.
• Vegetable broth: Chicken broth works perfectly if that’s what you have available. You can also use water with a couple of bouillon cubes in a pinch.
• Avocado oil: Any neutral cooking oil will do – canola, grapeseed, or just use all olive oil if that’s easier.
• Caraway seeds: These add a nice earthy note, but if you’re not a fan or don’t have them, you can skip them or substitute with a pinch of cumin for a different but still tasty flavor.
• Fresh thyme: Dried thyme works fine – just use 1 teaspoon instead of the tablespoon of fresh. The flavor will be slightly more concentrated but still delicious.

Watch Out for These Mistakes While Cooking

The biggest mistake when roasting garlic is not wrapping it tightly enough in foil, which can cause it to dry out instead of becoming soft and caramelized – make sure the foil packet is sealed completely with a little pool of oil around the bulbs.

Another common error is cutting your potatoes into uneven pieces, leading to some chunks being mushy while others stay hard, so aim for uniform 1-inch cubes that will cook at the same rate.

When blending hot soup, never fill your blender more than halfway full and always hold the lid down with a towel, as the steam can build pressure and cause the top to blow off.

Finally, resist the urge to skip simmering the vegetables long enough – if your potatoes aren’t fork-tender before blending, you’ll end up with a grainy texture instead of a smooth, creamy soup.

What to Serve With Potato Garlic Soup?

This hearty potato garlic soup is filling on its own, but I love serving it with a thick slice of crusty bread or a warm baguette for dipping. A simple side salad with mixed greens and a light vinaigrette helps balance out the richness of the soup and adds some freshness to your meal. If you want to make it more substantial, try adding some crispy bacon bits on top of the soup or serving it alongside a ham and cheese sandwich. For a cozy dinner, pair it with roasted vegetables like Brussels sprouts or green beans that have been tossed with a bit of olive oil and salt.

Storage Instructions

Store: This soup actually gets better after a day or two in the fridge as the flavors blend together. Keep it in an airtight container in the refrigerator for up to 5 days. It’s perfect for meal prep since you can just grab a bowl whenever you need a quick, comforting meal.

Freeze: Potato soup freezes pretty well, though the texture might change slightly when thawed. Let it cool completely, then store in freezer-safe containers or bags for up to 3 months. I like to freeze it in individual portions so I can thaw just what I need.

Reheat: Warm the soup gently on the stovetop over medium-low heat, stirring occasionally. You can also microwave it, but do it in short intervals and stir between each one. If it seems too thick after storing, just add a splash of vegetable broth or water to thin it out to your liking.

• Calories: 1400-1600
• Protein: 25-30 g
• Fat: 38-44 g
• Carbohydrates: 270-300 g

Ingredients

For the roasted garlic:

• 2 bulbs garlic
• 2.5 tbsp olive oil (I prefer California Olive Ranch for its mild flavor)

For the soup:

• 2 tbsp avocado oil
• 1.5 yellow onion
• 3/4 leek
• 1/2 tsp caraway seeds
• 3/4 tsp salt
• 2 carrots (diced into 1/2-inch pieces)
• 1 stalk celery
• 3 lb yellow potatoes (peeled and cut into 1-inch chunks)
• 1 bay leaf
• 6 cups vegetable broth (I always use Better Than Bouillon base)
• 1 tbsp fresh thyme
• 1/2 tsp black pepper
• 1/4 tsp smoked paprika

Step 1: Roast the Garlic

• 2 bulbs garlic
• 1.5 tbsp olive oil

Preheat your oven to 400°F.

Cut the top quarter off both garlic bulbs to expose the cloves inside, then place them cut-side up on a small piece of foil.

Drizzle with 1.5 tablespoons of the olive oil, wrap the foil around them loosely, and roast for 40-50 minutes until the cloves are golden and completely soft.

While the garlic roasts, you can prepare everything else—this is the perfect time management strategy since roasting happens independently.

Step 2: Prepare the Aromatic Base

• 1.5 yellow onion
• 3/4 leek
• 2 carrots
• 1 stalk celery
• 3 lb yellow potatoes
• 6 cups vegetable broth
• 1 bay leaf
• 1/2 tsp caraway seeds
• 1 tbsp fresh thyme
• 1/2 tsp black pepper
• 1/4 tsp smoked paprika

While the garlic roasts, dice the onion into small pieces and slice the leek (white and light green parts only) into thin half-moons.

Peel and dice the carrots into roughly 1/2-inch pieces, chop the celery into small pieces, and peel the potatoes, cutting them into 1-inch chunks.

Measure out your broth and have the bay leaf, thyme, caraway seeds, and spices ready.

Having all your ingredients prepped before the pot heats ensures smooth cooking and prevents any scrambling.

Step 3: Build the Flavor Base with Aromatics

• 2 tbsp avocado oil
• 1.5 yellow onion
• 3/4 leek
• 1/2 tsp caraway seeds
• 3/4 tsp salt

Heat the remaining 2 tablespoons avocado oil in a large pot or Dutch oven over medium heat.

Add the diced onion, sliced leek, caraway seeds, and salt, stirring occasionally for 8-10 minutes until the vegetables are very soft and translucent—this slow cooking develops a sweet, mellow foundation for your soup.

I like to let these aromatics cook a bit longer than the minimum time; it really deepens the underlying flavor of the finished soup.

Step 4: Add Remaining Vegetables and Broth

• 2 carrots
• 1 stalk celery
• 6 cups vegetable broth
• 3 lb yellow potatoes
• 1 bay leaf

Stir in the diced carrots and celery, cooking for 5 minutes to soften them slightly.

Pour in the vegetable broth and add the potato chunks and bay leaf, then bring everything to a boil over medium-high heat.

Once boiling, reduce the heat to medium-low and simmer for about 20 minutes, stirring occasionally, until the potatoes are completely tender and break apart easily with a fork.

Step 5: Finish and Blend the Soup

• roasted garlic from Step 1
• 1 tbsp fresh thyme
• 1/2 tsp black pepper
• 1/4 tsp smoked paprika

Remove the bay leaf from the soup.

Squeeze the soft, roasted garlic cloves out of their skins directly into the pot—they’ll have a mild, sweet, almost nutty flavor that’s completely different from raw garlic.

Add the fresh thyme, black pepper, and smoked paprika, stirring to combine.

Using an immersion blender, blend the soup until it reaches your desired consistency—I prefer a mostly smooth soup with just a few small potato pieces remaining for texture, but you can blend it completely smooth if you prefer.

Taste and adjust seasonings as needed.

Step 6: Serve

Ladle the warm soup into bowls and serve immediately with your choice of toppings such as crusty bread, fresh herbs, crispy croutons, or a drizzle of good olive oil.
