It is cold again up here. I suppose that is when I like to cook most. And when we found Gruyere cheese for sale at Whole Foods we had to make French onion soup. The recipe is from Julia Child and it is very easy aside from the time it takes to actually cook. I encourage you to try it. It was the best French onion soup I've ever had.
1 1/2 pounds yellow onions (or 4 large)
3 tbs. butter
1 tbs. oil
1 tsp salt
1/4 tsp sugar
3 tbs. flour
1 qt. stock (beef or chicken)
1 qt. water
1/2 cup dry white wine
2 oz. cognac or brandy
old bread (I recommend a nice crusty sourdough loaf)
1 cup grated Gruyere cheese
*please, go out and find Gruyere. It must say "Gruyere" - don't use anything else.
Chop the onions in thin strips. I halve and peel them, then simply slice them so they make little half moons. Melt the butter and oil in a heavy bottomed stock pot, add the onions and cook on low for 15 minutes with the cover on.
Uncover, raise the heat to medium, add salt and sugar, and cook the onions for 30-40 minutes. You will need to stir them every so often. And I encourage you not to have the heat too high. You are slowly developing color at this point not sprinting for the caramelized finish.
While the onions brown heat up your water and stock. You want to add it to the stock pot when it is boiling so as not to arrest the cooking process. If you have any beef stock to hand, I recommend it rather than chicken as it adds more color and flavour to the soup.
When the onions are a nice golden color, and the stock is hot (but not yet added); sprinkle the 3 tbs. flour over the onions and stir frequently for 3 minutes. Now it is time to add the stock - boiling hot mind you to prevent flour clumps from forming. And I recommend initially adding a cupful at a time and stirring it well. Once you think the flour has been incorporated - pour in the remaining stock. Add the white wine and bring the soup to a low simmer and cook partially covered for another 30-40 minutes.
Grate your cheese and cut a 1/4 inch slice of sourdough for each soup bowl. Find oven safe bowls and turn on your broiler. Taste your soup first, and add any extra salt if necessary. Ladle it into the bowls. You can under fill it so that you don't have the hazard of burning yourself with boiling hot soup. I left a good three quarters of an inch. Plonk your bread slice on top and smother the soup with gruyere.
Place the bowls on a tray under the broiler and crack the oven door so that you can watch them. The cheese will first melt, the it will begin to bubble. You may wish to gingerly slide out the tray and check for browning; but it could take a good five or ten minutes. If the soup is browning unevenly, rotate the bowls on the tray.
We served the bowls on plates so that we didn't have to worry about scorching ourselves.
Enjoy!
