About This Onion and Turnip Soup Recipe

When it comes to winter vegetables, there are few that are as hearty and satisfying as onions and turnips. And what could be more comforting on a cold winter day than a steaming hot bowl of soup made with these two humble ingredients?

Onions and turnips are both brassicas, a family of vegetables that also includes cabbage, broccoli, and Brussels sprouts. Brassica vegetables are known for their high nutrient content, including vitamins C and K, and for their many health benefits.

This onion and turnip soup is the perfect way to warm up on a cold winter day. The rich flavor of the onions is balanced by the slightly sweet taste of the turnips, while the addition of stock or milk gives the soup a creamy texture.

Onion and Turnip Soup Recipe Ingredients

Ingredient Notes

  • Onion: My go-to onion for this soup is the general yellow cooking onion because it is relatively cheap and plentiful. It has a mild flavor and is not overpowering.
  • Turnips: I like to use young turnips because they are sweeter and give a rich texture to the soup.
  • Potato: For me, the perfect potato for creamy soups is the Russet potato because it will soak up the liquid, lose its shape, and create a super creamy texture.
  • Vegetable Stock: It has a balanced flavor and more body than water and adds a lovely taste.
  • Rosemary: There’s no flavor quite like this woodsy aromatic herb. It adds notes of pine, sage, and evergreen.
  • Nutmeg: A pinch of nutmeg gives the soup a slightly nutty, woody, and sweet flavor.
  • White Pepper: I like to use white pepper in this soup because of its subtle aspect and flavor.

Ingredient Substitutions

  • Herbs: I like using rosemary, but you can experiment with different herbs such as Italian seasonings, thyme, oregano, or any other herbs you like.
  • Vegetable Stock: It can be replaced with any other stock. Chicken stock is a great option, too.
