DIRECTIONS
1.
For the Soup
1.
Begin by preparing your onions. Peel them and then cut in half from pole to pole - through the root and stem. Remove the tough root part by cutting it away with your knife. Then thinly slice them pole to pole - like cutting with the grain of the onion. This gives the slices more structural integrity so that they stand up to the slow cooking method.

Repeat this process with the rest of the onions.

Next prepare your stock. Ideally you would use homemade beef stock, but you can also “soup” up a store bought version.

6 cups high quality beef stock (or amped up store bought stock, see below)

4.
For the Amped Up Stock
1.
Add your beef broth to a stock pot and bring to a simmer. Add aromatics like parsley, sliced carrots, thyme sprigs, garlic, bay leaves, peppercorns, cloves, and parmesan rind. Let it simmer for 1 hour.

For the Soup
1.
In a large Dutch oven drizzle olive oil and let heat up for one minute. Dump in the sliced onions. It will look like way too many, but just trust me.

3 tbsp olive oil

3 lbs Spanish onions

Dutch oven
2.
Slowly caramelize the onions over medium heat. Keep them moving constantly, and scrape down the sides of the pot.

The onions are done when they are soft, jammy, and caramelized with a lot of fond on the bottom of the pot.

Deglaze the pot with dry sherry and cook, scraping up fond from the bottom of the pot.

Once the alcohol is cooked off, add the beef broth. Make sure to strain it first if you added aromatics.

Let the whole thing simmer for 5-10 minutes to let the flavors get to know each other.

Optional: add umami boosters. I like to add a splash of fish sauce and soy sauce to richen the flavors.
