The Beer Chicks Rad French Onion Beer Soup
In Los Angeles, we Beer Chicks know that fall is here when the clouds come onshore all the way up to Beverly Hills and it finally starts to rain (read mist). We know it by the crazy drivers who apparently only come out when it rains. But mostly we know it by an intense craving for our special Rad French Onion Soup made to perfection with the addition of Flanders Red Ale!
In order to make the perfect French Onion Soup, we've experimented with several "best" recipes featuring different "secret" ingredients ranging from Cognac, Sherry, Port Wine and dry white wine, but it wasn't until we heard about the addition of Balsamic Vinegar as the celebrated element that we got that spark of beer inspiration.
Why are we so excited about Balsamic Vinegar you might ask? Well, because the same fermentation (Lactobacillus) that gives Balsamic Vinegar its sizzle of puckering sour acidity is also used in one of our favorite beer styles, Flanders Red Ale.
A Beer Chick's mind is always going in ways that try and figure out how to add beer to everything, so out goes the Balsamic Vinegar and in goes the Flanders Red Ale. In this recipe we used a beer called Rodenbach from Brouwerij Rodenbach out of Roeselare, Belgium. Brewed since 1836, this beer is a blend of 75% young beer and 25% aged beer. This deep, dark red-brown ale is fruity, slatey and oaky, with a puckering tartness that harmonizes perfectly with the carmelized onions and cuts through the melted French Gruyere cheese of our perfect French Onion Soup.
The Beer Chicks Rad French Onion Soup
1/2 stick of butter
6 onions sliced
6 garlic cloves, sliced
1/2 cup Rodenbach Flanders Red Ale*
6 cups beef broth
1 teaspoon Sierra Nevada Porter Mustard**
1/8 teaspoon truffle oil (optional)
Salt & pepper
4 French bread slices, toasted
1 cup grated Gruyere cheese
Melt butter in heavy large saucepan over medium heat. Add onions and garlic and sauté until the onions are tender and very brown and carmelized (about 40 minutes). Add the Flanders Red Ale to deglaze the pan and simmer about 3 minutes. Combine beef broth and mustard and add to the saucepan. Simmer about 35 minutes. Add truffle oil and season to taste with salt and pepper.
Preheat broiler. Ladle soup into broilerproof bowls, making sure there is room for the toast and cheese. Top each bowl with slice of toast and grated cheeses. Broil until cheeses melt, brown and bubble.
Enjoy with a Flanders Red Ale or for a completely different but equally delicious pairing, try a peppery and citrusy Belgian Saison!
Other Flanders Red Ales that would be great with this recipe are Duchesse de Bourgogne from Brouwerij Verhaeghe, Vichte Belgium or La Folie from New Belgium Brewing Company, Fort Collins, CO.
*We love this mustard that we bought during a visit to Sierra Nevada Brewing Company in Chico, CA. You can substitute it with any Dijon mustard.
