French Onion Soup with Lager

I’ve always been a fan of the classic, French Onion Soup. So, when I was asked by a sponsor to create a recipe using beer, a French Onion Soup with Lager was the very first thing that came to mind.

French Onion Soup: A True Classic

The sweetness of caramelized onions, beefy broth and Gruyere cheese just seemed to call out “beer me”. Although I do like to experiment with beer in cooking, I’m not much of a beer aficionado (I leave that to my other half). Off I went off to the BCLDB to grab a six pack of Samuel Adams Boston Lager.

To say that I am not a beer aficionado, really means, that I’m just not a big drinker of beer. However, hubby cracked open a cold bottle and loved it. So I had a sip. It was good. Maybe I just haven’t tried enough craft beers, but this one had a really nice complexity of flavours. Which really inspired me to get cooking with it. I really got the hops and malt, and how they would be just amazing in this french onion soup recipe.

I wasn’t sure what to expect when I set out to make this french onion soup, because I’ve made it many times but, never with beer. I’m happy that I trusted my instincts, though.

French Onion Soup + Beer = Delicious

This French Onion Soup with Lager turned out to be amazing. Seriously, delicious. The lager in the soup perfectly complemented the sweetness of the onions with a just a hint of hops and malt. I would have to say that it was the best French Onion Soup that I’ve ever made.  And now my go to recipe.

Caramelize Those Onions

French onion soup is a classic but very simple dish. It’s super easy to make. But it’s important to keep in mind, that the key to the best onion soup is the slow caramelizing of your onions. You want to cook them slowly on low heat until they turn a golden brown. This is the most important part of the recipe. When you slowly caramelize the onions,  it brings out their sweetness and adds an important depth of flavour to your soup.

Best Bread Topping For Your Amazing Soup Is….

An artisan sourdough, French, or Italian bread is perfect for this recipe. You can even use leftover garlic bread. And it’s totally OK if your bread isn’t fresh. It’s going to soak up all of that beefy, sweet caramelized onion goodness. And then be covered in toasty melted cheese. Enjoy!
