French Red Onion Soup with Cheese toast is one of the best lunchtime soups in the winter. Flavored with three types of caramelized onions, red wine, and sherry. Lightly caramelizing the onions gives them a sweet, intense flavor that is irresistibly delicious. And together with a piece of crusty baguette with cheese au gratin (Gruyère), this is a real comfort soup. Enjoy until the last bite!
Red Onion Soup with Cheese Toast
Are you looking for real comfort food in the form of soup? Then for me, it is a delicious Onion Soup. Sometimes I make it very easy for myself and cook the onion soup with only six ingredients; super delicious! Or I have an onion soup with beer, which also tastes delightful. But if I want a deep, rich onion soup taste, I make this one.
The three types of onion that you lightly caramelize get a delicious sweet taste. The broth combined with red wine and sherry makes it velvety smooth. And if you let the baguette with cheese au gratin after pouring it, all the flavors are absorbed into the bread. Irresistible.
This recipe is slightly adapted from a recipe from Maaike's blog the answer is food.
What do you need for French Red Onion Soup with Sherry?
To prepare this Red Onion Soup with Cheese Toast, you need the following ingredients. You can find the correct amounts in the recipe card at the bottom of the blog:
French Onion Soup
- Red Onion, Shallot, and Yellow Onion - The base of the onion soup. We will slowly fry these three onions so that they caramelize and become sweet.
- Butter and flour - Together, they form a roux that makes the soup lightly thickened. Ensure you fry the flour-butter mixture for at least 2 minutes; otherwise, your soup will have a flour taste.
- Garlic - The garlic gives extra flavor to the soup.
- Sugar - Gives the soup a very light sweetness.
- Vegetable stock - Use vegetable stock as the base for the soup. Made from cubes or delicious homemade vegetable stock. You can also use beef broth if you want.
- Red Wine and Sherry - Give the soup a full, sweet, and sour taste.
Gruyère Cheese Toast Topping
- Baguette - Half-baked or fully baked. Cut into slices; this is placed on top of the soup and then roasted. This allows the baguette to absorb the delicious taste of the red onion soup.
- Gruyère cheese - This full-fat cheese melts well under the grill. It has a hearty taste that this full soup can have very well. It makes this red onion soup extra tasty.
- Parsley - Has a fresh taste and is added after roasting.
