What's in a name?
Having been schooled in stock making, I'm on team stock.
Guinness Caramelized Onion Soup
While store bought stock would have been fine, I wanted the deep beefy nuance of a collagen infused long simmered stock. With a little effort and a bit of time, stocks basically take care of themselves. Aside from some occasional scum skimming, they're pretty much hands off and fuss free. Good things come to those who wait, so bone up and enjoy the ride.
Roasting the bones and vegetables gives any stock depth, body, and intense flavor. Typically, the two are roasted separately. With a watchful eye, they can be roasted together. I scattered 4 pounds of meaty Marksbury Farm beef neck and shank bones onto a sheet pan along with 1 split leek, 2 chopped parsnips (unpeeled), 2 chopped carrots (unpeeled), 1 Large quartered Spanish onion (skin on), and 1 halved whole garlic head (skin on). After drizzling the meat and vegetables with olive oil, I seasoned them with salt and cracked black pepper before sliding them into a blistering 450 degree oven. After 30 minutes, I pulled the bones from the oven, brushed them on all sides with tomato paste, and returned them to the oven for an additional 30 minutes.
Blistered and caramelized, I pulled the roasted bones and vegetables from the oven, tumbled them into a large stock pot, deglazed the sheet pan with 1/2 cup sherry vinegar to release the browned tasty bits, and scraped the juicy fond into the stock pot. After covering the bones and vegetables by 2" with about 12 cups water, I added a few sprigs of fresh thyme, fresh rosemary, fresh parsley, 10 whole peppercorns, and 3 bay leaves. I brought the water to a boil, reduced it to a simmer, moved it to a back burner, and let it rip, skimming the scum from time to time.
Stocks and/or bone broths can simmer up to 24 hours. While 4 hours is a good start, a longer cook allows the collagens to seep from the bones and melt into the stock. I took a little under/over wager on the cook time. After 8 hours, I strained the stock through a cheese cloth-lined chinois into a clean stock pot, discarded the solids, quickly cooled the stock in an iced water bath, ladled it into mason jars, and slid it into the refrigerator to chill overnight.
Cry me a river.
Low and slow wins the race when it comes to coaxing the natural sugars out of sliced onions to achieve silky sweet onion candy. The standard method requires hovering over slowly bubbling onions for a very long time (sometimes hours), gently stirring them as they gradually soften, collapse, and caramelize from the heat. While a slow cooker ( on a 10 hour setting) would have alleviated the fussy attention, onions simmered in a slow cooker tend be softly browned rather than deeply caramelized. Direct contact with heat was key.
Crank the oven.
After slicing 5 pounds Spanish onions into 1/4" half moons, I tossed them into an oiled cast iron
dutch oven, added 2 tablespoons vegetable oil, 1 teaspoon salt, and 1 teaspoon cracked black pepper. I mixed the onions until they were coated with the oil, covered the dutch oven, and slid it into a 450 degree oven.
On 1 hour intervals, I pulled the onions from the oven, gave them a quick stir, covered the pot, and returned them to the oven.
After 3 hours, I pulled the onions from the oven and placed them over a medium flame on the stove top. After allowing the onions to saute for a second or two, I deglazed the pot with 1/4 balsamic vinegar, a splash of Irish Whiskey, and 1 cup dark Guinness Stout Beer. When the beer reduced by half, I added 5 cups of the reserved gelatinous beef stock, 2 bay leaves, and fresh thyme. I brought the soup to a boil, reduced the heat, let it simmer for 30 minutes.
I ladled the hot slippery soup into oven safe crocks, slammed back a shot of Guinness, floated toasted Sunrise Bakery baguette croutons over the soup, smothered the toasts and crocks with mounds of grated Irish Kerrygold Dubliner sharp cheddar cheese, and slid the bowls under a broiler.
When the bubbling molten cheese blistered from the flames and oozed down the sides of the crocks, I pulled them from the oven and let them settle down before finishing with a sprinkling of flaked sea salt and fresh thyme.
Suspended in the soup beneath the slightly charred cheddar ,the sweet caramelized onions punched through the creamy saltiness of the melted cheese, the buttery soft crunch of the toasted croutons, and the subtle bitter undertones of the stout-spiked stock.
Bad to the bone.
