I might be becoming more of a soup person…

It’s all because of this soup right here. A classic French onion soup made even more rich and flavorful with the addition of creamy Irish stout and sharp Irish whiskey.

The beer makes the base of this soup so delightfully indulgent, you feel like you are sitting in an Irish pub on a cold night sipping on a pint of Guinness. 

There are times when you just want to escape you know? It seems like everyone around me is running off to far off destinations in the coming months!

The bitter cold that set in here in Denver has me wishing I had a trip to plan as I try to avoid the world by staying indoors where it’s warm.

Yes, I know I just got back from Hawaii, but I’m already itching to get back out on the open road already.

This soup has cuddling up next to a roaring fire on a stormy night written all over it. Though this soup takes a little bit of time, those hours spent simmering over the stove really bring out the complex flavors in the soup and you’ll taste that effort in every sinful bite.

I love using white Irish cheddar on top of the toast because it has just the right amount of bite to balance out the richness of the broth.

Just make sure you serve it up with extra bread for dipping!

You all know this little bread bob over here can’t live with only ONE piece of toast on top of her soup 😉
