This silky smooth summer squash soup is loaded with fresh yellow squash, creamy potatoes, and the warm flavors of Summer. This easy Yellow Squash Soup is a great way to use extra squash from your garden or seasonal squash from your local store.

Every year I get a little too excited about planting my garden. Which means every year I have a ton of summer squash.  One year in particular I had so many yellow squash I really didn’t know what to do with them all.

I was talking to a friend and she told me about a yellow squash soup recipe that she had that was delicious.  My interest was peaked.  I started experimenting and ended up with this recipe that is so creamy, full of flavor and tastes like you ordered it from a restaurant.  And the best part is you can make a huge batch and freeze it and eat it when the weather turns cold and you are missing those warm summer days.

Ingredients You’ll Need to Make Yellow Squash Soup

• Summer Squash – there are lots of squash that are considered summer squash. For this recipe, you will want to use yellow squash. You can use bigger yellow squash, but the bigger they are the more seeds they will have and the tougher the rind will be. A medium size squash is best.
• Onion – white or yellow onion works for this soup.
• Potatoes – russet or yukon gold are great for this recipe.
• Garlic – fresh – you can use pre-minced or mince it yourself.
• Broth – if you want this soup to be vegetarian, use vegetable broth, otherwise chicken broth is great.
• Buttermilk – makes this soup creamy and adds a very milk tangy flavor that is sooooo delicious.

How to Make Yellow Squash Soup

1. The first step is to peel and cut up your yellow squash, potatoes, and onions.  You can see that I didn’t peel all of my yellow squash.  The ones that were smaller and had a smooth thin skin I just cut up and threw them in.
2. Saute the squash, onions, and potatoes until soft, about 10-15 minutes.
3. Next puree in batches in your blender.  If you use a high powered blender like a Blendtec it will seriously be so smooth. You can also use an immersion blender to get it nice and smooth.
4. This step really wasn’t necessary after using my Blendtec, but I ran it through a fine mesh sieve.  There literally were no chunks, but it made me feel like an overachiever and so I did it.
5. At this point is where you will add your buttermilk.  If you are going to eat it right away, serve it up in bowls.
6. It is delicious topped with a sprinkling of fresh herbs, a little Parmesan, or a dollop of sour cream.  

This yellow squash soup is creamy and surprisingly full of flavor.  I was surprised how much flavor it has considering it has only a few ingredients.  The smooth texture is a winner with kids and adults and so it has become one of the meals we like to include in our meal plan.  We serve this with some yummy homemade bread and it is a delicious meal that is so easy to make!
