Brussels sprout soup is a creamy, nutrient-packed dish that transforms this humble vegetable into a flavorful and comforting meal. Perfect for a light yet satisfying option. For more healthy soup ideas, check out my healthy soup recipes.

Vegetables are best eaten freshly cooked and leftovers look rather sad after being zapped in the microwave for a quick meal. (Hang on, did I just confess my guilt?!?)
The Brits came up with a clever idea of making bubble and squeak but there is only so much you can eat before you grow fed up of it. Here's another solution: soup.
The beauty of this soup is that it's a doodle to rustle up, and very quick if you're using cooked potato as well. That's right.
If you happen to have leftover roast potatoes or mash, you can use them instead of raw potatoes. You'll save time too by not having to cook the raw potatoes.
Just fry up some onions and garlic, add the leftover vegetables and stock, heat through the mixture and give it all a great big whizz with a blender until smooth.
It's as easy as that. Just keep an eye on the ratios you use - if you follow the recipe's you'll be fine.
Don't fret either if you served your greens or sprouts with bits. You know. Stuff like cheese, chestnuts, bacon or nuts. Chunk them all in for extra depth of flavour.
I had so much left over that I turned it into the soup you see now. Bacon, blue cheese and pecans all tipped in.

Add cream to the soup if you're feeling decadent. It can be spruced up with numerous toppings and this case I used blue cheese, bacon and chives.
Don't be afraid to use leftover gammon or turkey to make it a more sizeable meal. Another delicious way to enjoy Brussels sprouts is to sous vide. Learn how to sous vide them here. Happy Boxing Day!
