I promised you a recipe when I was feeling a bit better, and suddenly a week slid by! It’s not that I wasn’t feeling better (though suspected food poisoning that requires two days – TWO! Two entire days! – home from work does take a while to recover from); it’s just that the end-of-semester panic that seems to make many of my students momentarily forget how to write seemed to strike me too. The words dulled and tripped and, in the face of multiple fires breathing their way up and down Southern California and all the other apocalyptic promises of the impending end of the year, chose to stay inside, thank-you-very-much.
But it’s time to shed that cocoon and step back out, and besides, this soup, with its medley of root vegetables, apple for sweet tartness, and luxurious quantities of cream, is all the velvet goodness a winter table requires. Its inspiration comes from a gorgeous bowl at my sister’s wedding last fall – a soup so rich and luxe and flavorful it was practically a down comforter. I knew it had root vegetables in it, I knew it had cream and herbs, maybe butternut squash, maybe sweet potato… so I wrote to the catering director at the venue and got into a very silly standoff: I wanted an email with a recipe, she wanted me to call (during HER business hours, east coast time – didn’t she know I was at work too? Didn’t she know I abhor phone calls?!) so she could tell me how she makes it, which sounded more like procedure than like an ingredient list with quantities. This went back and forth for a week, with me refusing to call and her refusing to provide a recipe, and finally I just gave up. Ten months later, the time to recreate the soup arrived, and I had only my muted memories from a night soaked in champagne and joy to go on.
To that end, I have no idea how close this is to the original. I picked sweet potatoes, parsnips, and celery root for an intriguing background flavor – you could change up the vegetable choices and use winter squash, or carrots, or even rutabagas. I suspect the venue’s version had even more cream, and I don’t think it included the spritz of nutmeg I added (mostly for looks, but we liked the flavor of it too), but there’s something about pouring in over a cup of heavy whipping cream and watching the contents of the pot go from bright orange to decidedly pale gold that makes a home cook’s arteries start whispering threats. I also don’t think the venue added a last minute slug of irish whiskey, but I’d recommend that you do, since just that little bit somehow rounds out the flavor in a way nothing else could.
What I do know is: this is cozy. It’s smooth, and rich, and pleasantly filling, and would be perfect with a bright, citrus-spiked salad full of radishes and pomegranate seeds and bitter lettuces.* And a thick wedge of bread to round things out. Maybe this one. And it leaves me lacking only one soup, with three weeks to go, to make this project complete.
Makes 10-12 first course servings; about 6 main course servings
About an hour
4-6 cloves garlic
4 tablespoons unsalted butter
1 medium white onion, diced
5 cups chicken or vegetable stock
2 cups peeled and diced celery root
2 cups peeled and diced sweet potato
2 cups peeled and diced parsnips
1 green apple, peeled, cored, and diced
3 sprigs fresh thyme (plus more to serve, if desired)
1 sprig fresh sage (4-5 leaves)
1 bay leaf
1½ cups heavy cream
1-2 ounces whiskey, brandy, or marsala, optional
1-2 teaspoons salt, to taste
sprinkle of nutmeg, to serve
- Set the oven temperature to 350F. In a small, oven-safe bowl, drizzle the garlic cloves with a little bit of olive oil, some salt and some pepper. Top tightly with aluminum foil and stow in the oven until the garlic smells sweet, 20-25 minutes. There’s no need to wait for the oven to preheat.
- While the garlic is roasting, melt the butter in a large pot over medium heat. Add the diced onion and cook gently with 2 pinches of salt until the onions are tender and slightly translucent, but not browned. This is called sweating, and should take 8-10 minutes, during which time you can peel and dice the other vegetables.
- With the onions softened, pour in the stock, then dump in the diced celery root, sweet potatoes, parsnips, and apple. Stir in the thyme, sage, and bay leaf, then raise the heat, cover with a lid, and bring to a boil.
- Once the liquid is boiling, reduce the heat to medium or medium low, keeping the soup just at a simmer until the vegetables are fork-tender: easily speared but not disintegrating; about 30 minutes. The apple will be softer than the others; the celery root will likely take the longest.
- When the vegetable chunks are tender, remove from heat and add the roasted garlic – once it has cooled a bit from its time in the oven, just squeeze the cloves right out of their skins, and straight into the soup. Then, very carefully and working in batches, relocate the soup to a blender and blend until very, very smooth. Hot liquids can expand rapidly in the blender, causing small “explosions,” so leave some room in the top, leave a space with the lid for air to escape, and consider covering the top with a thick kitchen towel just in case.
- Transfer the smooth soup back to the pot. If you’re feeling especially fussy, you could try straining it first. I didn’t, but if you do, let me know how it goes!
- Back in the pot, stir in the heavy cream and the alcohol, if using, and the salt. Start with 1 teaspoon, taste, then add more if you feel the soup needs it. Return to low heat until warmed through.
- To serve, ladle into bowls, dust lightly with nutmeg, and top with a sprig of thyme if you’re feeling fancy.
