If you’re someone who thinks garlic makes everything better, this soup was made for you. Two whole heads of garlic go into this pot, and honestly, it’s not too much. The roasting mellows everything out so you get that deep, sweet garlic flavor without any sharpness.

I started making this soup years ago when my mom was going through a phase where she wanted to try every potato soup recipe she could find. This one stuck. Now I make it every time the weather turns cold or when someone in the house is feeling under the weather. There’s something about a warm bowl of this stuff that just fixes things.

My grandmother used to say that garlic was the answer to everything, and while I’m not sure that’s medically accurate, this soup makes a pretty good case for it. I remember her standing at the stove, squeezing those roasted garlic heads and muttering about how store-bought soup could never compare. She was right. Every time I make this, I think about her kitchen and how it always smelled like something good was happening.

What makes it work is the mix of russet and red potatoes. Russets break down and thicken the broth while the red potatoes hold their shape and give you something to chew on. Add in leeks, fresh thyme, and those crispy garlic chips on top? You’ve got yourself a bowl that feels fancy but comes together in about 30 minutes of active cooking time.

Why You’ll Love This Recipe

This is the kind of soup that makes you want to curl up on the couch with a blanket and not move for hours.

Garlic flavor that’s bold but not overpowering: roasting the garlic heads takes away the bite and leaves you with something almost sweet.
Two types of potatoes: russets for creaminess and red potatoes for texture. You get the best of both.
Ready faster than you’d think: most of the time is hands-off simmering while you do other things.
Impressive enough for company: those garlic chips on top make people think you worked way harder than you did.
Freezer-friendly: make a big batch and stash some for later when you don’t feel like cooking.

Ingredient Notes and Substitutions

You can tweak this recipe to fit what you’ve got on hand or what you’re in the mood for.

Chicken broth: Chicken broth adds tons of flavor. But if you want it to be truly a vegetarian soup, vegetable broth is just as flavorful. Just make sure it’s got good flavor on its own.
Heavy cream: Half-and-half is fine if you want something lighter. I wouldn’t skip it entirely, though, because it adds body.
Leeks: A medium yellow onion can stand in if you can’t find leeks. The flavor’s a bit different but still good. Or sweet white onion works just as well.
Russet potatoes: Yukon Golds work too, they just won’t break down quite as much. They do tend to make a potato soup extra creamy.
Fresh thyme: dried thyme is OK in a pinch. Use about half a teaspoon since dried herbs are stronger.

Tips for Success

A few things that’ll help you nail this soup every time.

Use fresh garlic: old garlic that’s starting to sprout will taste bitter. You want firm heads with tight skin.
Don’t rush the leeks: low and slow is the way. Burnt leeks will make your whole soup taste off.
Watch your garlic chips closely: they go from golden to burnt in about 30 seconds. Stay right there at the stove.
Blend to your preference: like it chunky? Blend less. Want it smooth? Go longer. It’s your soup.

Storage and Reheating

Let the soup cool down completely before you put it away. Storing it while it’s still hot creates condensation, and nobody wants watery soup. Keep it in an airtight container in the fridge for up to 5 days.

To reheat, warm it up on the stove over medium-low heat. You might need to add a splash of broth since it thickens as it sits. Microwave works too for single servings.

You can freeze this soup for up to 3 months. Pour it into freezer bags and squeeze out the extra air. Leave some room at the top because it expands. Thaw overnight in the fridge before reheating.

Serving Suggestions

A crusty loaf of garlic bread is pretty much mandatory here. The way it soaks up the broth is honestly half the point.

For something fresh on the side, a simple cucumber, tomato, and avocado salad cuts through the richness. Or just throw together a green salad with a light vinaigrette.

Grilled cheese sandwiches are also a solid choice. My kids think that’s the only way to eat this soup, and I’m not going to argue with them.

FAQs

Can I eat potatoes that have started sprouting?

Yes, but cut off the sprouts first and toss them. The potato itself is still fine to use as long as it’s firm and not wrinkly or green.

What if I don’t have an immersion blender?

Transfer about a cup and a half of the potatoes with some broth to a regular blender and pulse until smooth. Pour it back into the pot and stir it in. You might need to do this in batches.

Is this creamy chowder actually healthy?

Potatoes get a bad rap, but they’ve got vitamin C, potassium, B6, and fiber. The cream adds some fat, but you’re not eating a huge amount per serving.

Notes

As I said, I always think of my grandmother when I make this delicious potato soup. She taught me that meals don’t have to be complicated, and a bowl of hearty soup can be just as filling as a huge meal with lots of different dishes.
