But, before you lose all hope, let's talk about this delicious concoction in detail and figure out a way to include it in your keto diet.
Is French onion soup keto-friendly? Before we answer this, let's step back in time and find out how this delicacy came to delight our taste buds.
Most people can tell that French Onion Soup is a delicacy of France. However, you'll be surprised to know that while the modern French onion soup does come from France, its delicious history dates back way earlier than you expected.
Let's think of it this way; there are two variations of French onion soup. The first one dates back quite a few centuries to the Romans. The second dates back to France. Even with historical differences, the two are pretty similar.
In the olden times, when the Romans were still conquering land, civilians and poor people boiled onions and any available stock/water together. The onion soup was very common with Roman peasants because onions were one of the few vegetables you could grow quickly and cheaply back then.
The Romans cooked different variations of onion soups as they got their hands on better crops, and over time, onion soups were one of the most popular dishes. But with the Romans' defeat, the soup barely made it to other civilizations and remained a delicacy amongst the peasants.
Many believe that back in the 18th century in France, the then King Louis XV got hungry and only found onions, champagne, and butter. Not wanting to go back to bed on an empty stomach, he boiled the ingredients together, and voila, he made the first French onion soup.
The history of French onion soup is a little complicated, and many people question it. But we're not here to debate over French onion soup's record; we know it's incredible, so why fight over where it originated?
I wasn't just telling you the history of French onion soup for no reason; due to its different variations, there are many recipes for this French delicacy. To make the simplest French onion soup, you would technically blend in onions, champagne, and butter, right?
While it seems from the original recipe that this is the mixture you should use, French onion soup evolved much more after King Louis XV discovered it. The simplest, tastiest, and the most authentic French onion soup recipe includes croutons, onions, wine, and gratinéed cheese.
French onion soup is rich in antioxidants, vitamins, and minerals. It is also a great source of fiber. However, French onion soup contains a lot of carbs, which is why the traditional recipe of French onion soup is not keto-friendly.
