Spanish Onion Soup | More Flavorful than French Onion Soup

This Spanish Onion Soup is one of the most flavorful onion soups I have ever tasted. Its got a ton of different flavors, it´s easy to make and made with very simple ingredinets. If you´re a fan of French onion soup, this Spanish version will blow you away.

Spanish Onion Soup
This soup is the perfect dish for any time of the year. As you can serve it either piping hot or even at room temperature. Either way, it´s always going to fill your body with so much goodness.

Spanish Onion Soup
To make this dish, I used regular brown onions. But you can use any onions you like. However, if you use sweet onions, make sure to season the soup well, so the flavors are well balanced.

    Excellent dish — quick and fun to make while finishing the bottle of wine! Next time we might add a little chopped tomato on top to add some acid/brightness. I will be making this a lot in 2022! Thank you!
