As it turns out, when you start to conceive a soup for March, there are a number of things to think about. Which half – the “in like a lion” or the “out like a lamb” part – do you capture? Do you take into account Punxsutawney Phil’s ominous scrabblings, or do you celebrate the early vestiges of the spring you feel coming? Do you blitz together creamy, lingering winter flavors, or do you fly light and bright and vegetal, in hopes of what might be just over the horizon?
If you’re me, you mull, you consider, you scribble, and then you try to do all of the above. For some people (read: east coast food snobs foodies), the emergence of ramps is the harbinger of spring. For me, it’s asparagus. I like the image of the little fern-like tops pushing their way up out of the cold ground, extending into bold, fat, turgid stalks. It’s not the likeliest vegetable to put into a soup, but it’s such a welcome green flavor that I wanted to celebrate it. The grassy character of asparagus got me thinking about cream of celery soup, one of those condensed classics that I’ve never actually eaten from a bowl, but have seen on any number of casserole recipes right up there with its gloopy mushroom cousin.
Cream of asparagus soup sounded comforting and easy, but what really got me excited was the prospect of garnishing it. A few Christmases ago, one of our appetizer options was wrapped asparagus: one set lovingly encased in wafer-thin strips of prosciutto; the other bundled into swaths of smoked salmon. And combining my childhood recollection of crackers crushed into soup for texture and the number of smoked salmon Caesar salads with homemade croutons we’ve had lately, my soup toppings seemed set. The prosciutto would be crisped in the oven and float tantalizingly on the creamy surface, and the salmon would be piled right in the middle for a treasure chest you could drag your spoon through on its way to a rubble of crouton.
Of course you wouldn’t eat the soup with both garnishes – prosciutto and smoked salmon (although, for the purposes of photographing each we did, in fact, have both), but two toppings seemed like a nice option to give you. I’ll be honest: we liked the salmon best, and definitely dug the croutons, but the prosciutto does go well with the soup’s flavor profile.
This was delicious – creamy and comforting – but the real excitement came when we sat down to eat it. I turned the heat on our gas stove down to low in case we wanted seconds, finished my photo session, toppings arranged just so, and brought two steaming bowls over to the couch where we were set to embark on a thrilling Friday night: soup and a British murder mystery, and no sooner had the ominous intro music begun to play than the power went out. We sat, we waited a few moments, we relocated to the table and lit a few candles, and then we ate soup in the semi-darkness, with the wind outside ripping down branches and the rain sheeting over the roof (we’re still in Los Angeles, right?), and were pleased to be indoors, with gas heat, and warm soup, and the whole weekend still to come.
A few notes: if you want the excitement of finding asparagus tips threaded through the smoothness of your soup, you can, as we did, leave them aside until after you puree. If you don’t want the disruption, add them along with the stalks and blend away.
However you choose to puree the soup – handheld or regular blender – be sure to be thorough. Unexpected snippets of leek or onion mar our velvet intentions and need to be blitzed into oblivion.
Be sure to cook the croutons until they are quite crisp. I like a salad crouton with a tiny bit of chewy give in the center, but here, the soup soaks in and the cubes need to be fully dry to avoid turning to instant mush.
Creamy Asparagus Soup with Two Garnishes
Adapted from Jamie at Home
About 45 minutes
For the soup:
4 tablespoons butter
1½ cups diced white onion (1 medium or ½ large)
1 leek, white and pale green parts only, halved, cleaned, and thinly sliced
2 stalks celery, cleaned, thinly sliced
1½-2 pounds asparagus, woody ends snapped off, cut into 1-inch pieces
1 quart water (4 cups) (you could use broth here, but I wanted to keep the flavors veg-central)
salt and pepper to taste
¼-½ cup heavy cream
1-2 teaspoons lemon juice
1-2 tablespoons chives, very thinly sliced
For the prosciutto garnish:
4 slices prosciutto
For the salmon and crouton garnish:
3 cups ½-inch sourdough bread cubes, cut from about ⅓ of a large loaf or batard
4 cloves garlic, minced, or ¾ teaspoon garlic powder
zest from one lemon
½ teaspoon black pepper
¾ teaspoon salt
3-4 tablespoons olive oil
4 ounces smoked salmon
- In a large pot, melt the butter over medium heat. Add the onion, leek, and celery pieces and turn the heat down to medium low. Sweat the vegetables for about 10 minutes – we are looking for tenderness, not for color. If they begin to brown, turn down the heat.
- While the vegetables are cooking, begin work on your garnishes – see instructions below.
- When the vegetables are tender and the onion pieces have become translucent, add the water and the asparagus stalks, reserving the tips if desired. Turn up the heat and bring to a boil, then reduce heat to keep the liquid at a bare simmer for about 20 minutes, until the asparagus pieces are tender.
- Blend extremely well using a handheld or a standard blender – you are looking for a completely smooth mixture. Season to taste with salt and pepper.
- If you have reserved the asparagus tips, add them now and simmer just until they are tender, about 5 minutes.
- Pull the pot off of the heat, add the cream and stir, then return to low heat, add lemon juice and chives, and warm through.
- To make the prosciutto garnish, while the onion, leek, and celery are cooking, preheat the oven to 300F and spread out 4 pieces of prosciutto on a baking tray lined with parchment paper. Bake at 300F for 20-25 minutes, until they are crisp enough to shatter.
- Set aside until soup is ready and serve balanced on the edge of the bowl, crumbled over the soup, or with one end immersed for drama, as above. Eat immediately; it will not remain crisp for long once it hits the hot liquid.
- To make the crouton and salmon garnish, while the onion, leek, and celery are cooking, preheat the oven to 300F. In a large bowl, whisk together the minced garlic or garlic powder, the lemon zest, the salt, and the pepper. Add the sourdough cubes and toss well to combine.
- Spread the seasoned bread cubes out on a baking tray and toast in the 300F oven for 20-25 minutes, until they are thoroughly dried inside.
- While the cubes toast and the soup simmers, unwrap the smoked salmon and use two forks, back to back, pulling away from each other, to shred it up.
- To serve, after ladling in a serving of soup, place a small mound of the smoked salmon in the center of the bowl, then place a handful of croutons over the top. As you can see, for aesthetic purposes I piled mine to the side, but you can put them right in the middle if you wish. Eat immediately.
