Cream Cheese Buttermilk Leek Soup

Cream Cheese Buttermilk Leek Soup
Admittedly, this Cream Cheese Buttermilk Leek Soup was “leftovers” inspired. So every time a recipe calls for buttermilk, I always end up with leftovers. Rolling that leftover buttermilk into a yeasted sheet cake seemed like a good idea. However, the recipe called for two cups and I only had one. So back to the drawing board.

Meanwhile, a bunch of leeks was wilting in the crisper, crying out to be useful. Incidentally, many German soup recipes use “frischkäse”, or soft whipped cheese. This is essentially cream cheese. Luckily, I had an 8 oz. package on hand so that’s how this soup came together.

Substitute Regular Milk:

The soup is creamy and hearty. You can substitute regular milk for the buttermilk. The result will be less tangy but add some extra seasoning to compensate for it.

Adding cream cheese to soup is a game-changer for both taste and texture! Here are some delicious reasons to toss that creamy goodness into your pot:

1-Luscious Creaminess: Cream cheese transforms any soup into a velvety masterpiece, giving it a rich, smooth texture that feels like a warm hug for your taste buds.

2-Flavor Boost: It brings a subtle tang that adds depth and complexity to your soup, taking it from basic to “What’s your secret ingredient?!” levels.

3-Thickens Like a Dream: Forget flour or cornstarch—cream cheese naturally thickens your soup without the fuss, making every spoonful more satisfying.

4-Pairs with Everything: Whether it’s a cheesy broccoli soup, creamy tomato bisque, or even a spicy chili, cream cheese blends effortlessly into almost any flavor profile, balancing and enhancing the taste.

5-Elevates Leftovers: Got a basic leftover soup in the fridge? Toss in some cream cheese and watch it become a whole new dish. Soup makeovers are real!

6-Protein & Fat Boost: Not only does it make your soup tastier, but it also adds a little more protein and healthy fats to keep you full and satisfied longer. Guilt-free indulgence!

7-Melts Like Magic: Unlike some cheeses that get stringy or clumpy, cream cheese melts smoothly into the broth, ensuring every bite is consistently creamy.

Cream cheese is the not-so-secret ingredient that’ll take it to the next level.
