5 -6 cups yellow onions, thinly sliced ( about 1 1/2 to 2 lbs.)
1 tablespoon cooking oil
2 tablespoons butter
3 tablespoons flour
6 cups parve vegetable stock
1-cup wine (dry red or white)
1 bay leaf
1/2-teaspoon ground sage
salt and pepper
12 ounces Swiss cheese, grated
4 ounces Parmesan cheese, grated
1/2 raw yellow onion
2 -3 tablespoons kosher cognac or brandy
8 slices French bread ( about 1 inch thick)
4 tablespoons olive oil, for drizzling
Place heavy bottom stockpot or Dutch over medium-low heat.
Add 1 Tbs cooking oil and 2 Tbs butter to pot.
Add sliced onions and stir until they are evenly coated with the oil.
Cover and cook for about 20 minutes until they are very tender and translucent.
To brown or caramelize the onions turn heat under pot to medium or medium high heat.
Add 1/2 tsp sugar and 1 tsp salt and continue to cook uncovered, stirring frequently until the onions have browned and reduced significantly.
Once caramelized, reduce heat to medium-low and add 3 Tbs flour to the onions.
Brown the flour for about 2-3 minutes trying not to scorch it. (If the flour does not form a thick paste, you can add a bit more butter here).
Stir in about 1 cup of warm stock, scraping the bottom of the pan to get up all of the cooked-on bits.
Add the rest of the stock, wine, sage, and bay leaf to the soup.
Simmer for 30 minutes.
To make the "croutes" (toasted bread), heat oven to 325 degrees F.
Drizzle each side of the bread slices with a bit of olive oil and place on baking sheet.
Cook the croutes for 15 minutes in oven on each side (30 minutes total).
Check the soup for seasoning and add salt and pepper if needed.
Remove the bay leaf (if you can find it).
Transfer to a casserole dish.
At this point you can add the 2-3 Tbs cognac (or brandy) and grate the 1/2 raw onion into the soup.
Add a few ounces of the Swiss cheese directly into the soup and stir.
Place the toasted bread in a single layer on top of the soup.
Sprinkle the rest of the cheese in a thick layer on top of the bread. making sure to cover the edges of the toast to prevent burning.
Drizzle with a little oil or melted butter.
Place in a 350-degree oven for about 30 minutes.
Turn on broiler and brown cheese well.
Let cool for a few minutes.
This soup may be prepared dairy as in the above recipe, which uses butter, cheese and vegetable stock. Or omit all of the cheese, and make it vegan.
For parve or meat, omit all of the dairy ingredients by substituting olive oil for butter and omit the cheese. You may want to try Daiya brand cheese substitute – which is parve and kosher.
Although the soup in this video clip is not "kosher", you may want to watch the legendary Julia Child create the original dish. She certainly offers many good tips!
