Creamy vegetable and whey soup is an easy and delicious way to use up extra whey. Warm and comforting, it is as perfect as a cup of soup for lunch, or served with bread and a salad for dinner.

Don’t waste the whey

It is a huge waste to pour whey down the drain. Sweet whey is healthy and delicious, which is why I have so many recipes that use up whey. Whey soup is definitely one that I enjoy every time I make cheese.

Ingredients

2 tablespoons extra-virgin olive oil
1 onion, roughly chopped
3 cloves garlic, minced
2 cups of vegetables, roughly chopped (see below for flavours)
2 large potatoes, diced
3 cups of broth
2 cups of sweet whey (see notes)
1 tsp salt, to taste
1/2 tsp ground black pepper, to taste
1/2 cup of heavy cream

Instructions

Place olive oil and onions in a soup pot, and saute for 5 minutes. Add in the garlic, potatoes and vegetables, and saute for another 5 minutes.
Pour in the broth and bring to a simmer. Simmer until the vegetables are soft, about 20 minutes.
Add in the whey, seasonings and cream, then puree until smooth. I usually remove a few of the signature vegetable and add them back after pureeing. It’s nice to have a few slices of mushroom or a broccoli floret in your soup bowl.
If you need to reheat the soup at this point, do it carefully. You don’t want to simmer at this point or the whey will curdle.
Serve with some grated cheese and delicious sourdough bread.

Notes

Acidic whey (from an acid curded cheese) will be quite sour. Even the 2 cups of sweet whey (from cultured cheese) can be quite strong in this soup. Sweet whey becomes more acidic as it ages, so start with just 1 cup of whey, and taste it before adding a second cup.
I like soups that have protein, so they become part of a complete meal. To add protein to this soup, replace the potatoes with 2 cups of white beans or 1 cup of almond flour.
I use an immersion blender, however, you could use a regular blender or just leave the vegetables whole.

Types of vegetable soups

This is a basic cream of vegetable soup recipe that has the added richness and tang of a few cups of whey. It is perfect for all different types of creamy vegetable soups. Here are a few of my favourites:

Irish Vegetable Soup: Finely dice the onion, garlic and potatoes. Add in 2 diced carrots and 2 cups of shredded cabbage. Follow the recipe, sauteing all the vegetables before adding the broth. Leave the vegetables chunky and serve with buttered brown bread.
Cream of Broccoli Soup: Use 2 cups of chopped broccoli for the vegetables. You can even use the stems, just peel off the woody bits. Remove a few whole florets before pureeing, then stir the florets back in and top with grated Parmesan cheese.
Cream of Mushroom Soup: Slice 3 cups of mixed mushrooms. Saute until they release their juices, then add in the onion, garlic and potatoes. Fry for 5 more minutes and finish the soup according to the recipe.
Lemon and Asparagus Soup: This is ideal for using up acid whey. Trim and chop 1 bunch of asparagus. Add it to the soup when you add the broth. Finish the soup with the zest of 1 lemon. The acidity of the whey will replace the lemon juice. Top each bowl with grated Parmesan cheese.
Baked Potato Soup: Instead of adding 2 cups of vegetables, use a total of 4 potatoes. Otherwise, follow the recipe as directed, then top each bowl of soup with a spoonful of sour cream, crumbled bacon, finely chopped chives and grated cheddar cheese.
Vichyssoise: Whey really adds a bit of zest to this classic soup. Don’t use any garlic, and use 6 medium leeks for the vegetables. Wash the leeks carefully, then chop and saute with the potatoes. Follow the rest of the recipe as directed, and serve hot or cold.
