German Cauliflower Soup - quick and easy, made just like Oma!

Here's a cauliflower soup recipe that you can adjust to your liking. Make it creamy. Make it chunky. Make it either way, and you'll get rave reviews for this vegetarian soup recipe.

This is a new soup for me. It's from an old, old German recipe for blumenkohlsuppe.

Hubby says, "Hmmmm ... this is GOOD!" Will definitely make this again and again. Not just because it's so good, but it's so easy to make. Isn't that the whole idea behind this website? Quick German recipes. Well, this is one of them!

Now, if you're looking for a vegan cauliflower soup, then you really need to check out my daughter-in-law Sylvie's version of her creamy 'cheesy' vegan cauliflower soup below. It's creamy, it's 'cheesy', it's rich, and quite easy to make.

I love using my cauliflower soup as a starter course for a dinner party. It has that taste of elegance. This is one of the great vegetable soups you can make when you've got an abundance of veggies.

Even veggies that are starting to be past their prime. Perhaps you've had a very successful trip to the Farmer's Market and want to enjoy something just a tad special with all those cauliflowers you bought.

Make this!

Vicki's version of the cauliflower soup recipe, with broccoli!

Above, this variation of the cauliflower soup recipe was made by my daughter-in-law, Vicki. She added a few extra ingredients to this one! Frozen broccoli, a little bit of parsley, and Vegeta for extra seasoning.

A Bit Of This and a Bit of That ...

• If you do not have a immersible stick blender, and you want a real cream of cauliflower soup, you can put the cooked cauliflower with a bit of the cooking liquid into a blender before returning it to the soup.
• Season with some nutmeg if desired.
• Try adding a touch of lemon juice to season at the end. (Thanks to Elke Miller for suggesting this!)

German Cauliflower Soup Recipe (Oma's Blumenkohlsuppe)

Here's a cauliflower soup recipe, aka blumenkohlsuppe, that you can adjust to your liking. Make it creamy. Make it chunky. Make it either way, and you'll get rave reviews for this vegetarian soup recipe.

With its taste of elegance, it's a perfect starter course for a dinner party. 

Prep Time:

15 minutes

Cook Time:

20 minutes

Total Time:

35 minutes

Servings:

Makes 4 servings

Ingredients:

• 1 small head of cauliflower, about 1 pound (454 grams)
• 1 teaspoon (6 grams) salt
• 3 tablespoons (42 grams) butter
• 6 tablespoons (48 grams) all-purpose flour
• 1 egg yolk
• 3 tablespoons (45 milliliters) cream, 10% or higher
• salt and freshly ground black pepper, to taste

Instructions:

1. Wash and trim the cauliflower, then cut it into small florets. Place the florets into a medium-sized pot with just enough water to cover. Add the salt.
2. Bring to a boil over high heat. Reduce the heat, cover, and simmer until tender, about 15 minutes.
3. Drain the cauliflower into a sieve, reserving the cooking liquid.
4. In the same pot, melt the butter over medium-low heat. Add the flour and stir. Cook for about a minute, but do not let it brown.
5. Stir in about 4 cups (960 milliliters) of the reserved cooking liquid. Bring to a boil, reduce the heat, and let it simmer for several minutes until thickened, then remove from heat.
6. Meanwhile, mix together the egg yolk and cream. Take about ¼ cup (59 milliliters) of the hot soup and stir it into the egg yolk mixture to temper it.
7. Stir the egg yolk mixture back into the soup. Add the cooked cauliflower and season with salt and pepper.
8. Use an immersion blender to make the soup as smooth or as chunky as you like, and serve.
