Sweet Pea & Spinach Soup
Deglaze softened onions with sherry to build a concentrated base, simmer sweet peas and spinach until tender, then blend the soup velvety-smooth and finish with a swirl of cream. Simmering long enough to break down the peas' skins is the secret to a flawlessly smooth, vivid green purée — spring in a bowl, elegant enough for a first course.
Few colors say spring like the vivid green of a good pea soup — bright, fresh, and full of the season's sweetness. This one pairs tender sweet peas with baby spinach and a whisper of dill, deepened by a splash of sherry and rounded with cream. Velvety and elegant, it can be served hot on a cool evening or chilled on a warm afternoon, always looking as vibrant and alive as the garden it came from.
Sherry to Concentrate
A simple pea soup can taste flat, so this one builds depth from the start. Soften the onion in butter until translucent, then deglaze the pot with dry sherry and cook it down until the sharp alcohol scent burns off and the liquid reduces to a thick syrup. That concentrated, nutty base is the flavor foundation everything else builds on — the reason the finished soup tastes rounded and savory rather than merely sweet and green.
Simmer, Then Purée Velvety
Two steps guarantee a flawlessly smooth soup. First, simmer the peas and spinach in the broth a full twenty minutes — long enough for the tough outer skins of the peas to break down completely, which is what lets them purée without any grit. Then blend aggressively until the soup turns silky and bright green. Stir in the cream over low heat at the end, and take care never to let it boil once the dairy is in, or it may break and lose its luxurious smoothness.
Sweet Pea & Spinach Soup
Ingredients
Method
- Heat the 2 tablespoons of unsalted butter in a large, heavy-bottomed soup pot or Dutch oven over medium heat until melted and foaming.
- Add the finely diced white onion and cook, stirring occasionally, until deeply soft and completely translucent, about 5 minutes.
- Pour in the ½ cup of dry sherry to aggressively deglaze the pot, scraping up any caramelized sugars from the onions. Cook vigorously until the sharp alcohol scent burns off and almost all of the liquid disappears into a thick syrup, about 4 minutes.
- Immediately stir the thawed sweet peas and fresh baby spinach directly into the hot onion and sherry reduction. Cook just until the spinach wilts slightly.
- Stir in the 2 tablespoons of fresh lemon juice and drop the whole fresh dill sprigs into the pot.
- Pour in 3 cups of the chicken broth. Bring the liquid to a rolling boil over medium-high heat.
- Once boiling, reduce the heat to low, cover partially, and simmer the soup gently for 20 minutes. This critical phase ensures the tough outer skins of the peas break down entirely, softening the vegetables for a flawless puree.
- Remove the pot from the heat and allow the soup to cool slightly to room temperature to prevent expansion blowouts.
- Using a high-speed immersion blender directly in the pot (or working carefully in batches with a standard blender), aggressively puree the softened vegetables and broth until they transform into a completely smooth, velvety, bright green liquid.
- Return the pureed soup to the pot over low heat. If the blend is too thick, stream in the remaining 1 cup of chicken broth to achieve your desired consistency.
- Vigorously stir in the kosher salt, coarse black pepper, and the ½ cup of heavy whipping cream. Do not allow the soup to boil once the cream is added, or the dairy may break and separate.
- Ladle the hot soup into shallow bowls and garnish heavily with a dollop of cold sour cream and a tiny sprig of fresh dill to provide a sharp and visual contrast.
The Heart of the Table
To open a meal with a small bowl of something this vivid is a quiet celebration of the season — a green so bright it looks like spring itself, offered as a gesture of freshness and care. There's generosity in a first course that asks nothing but to be admired and enjoyed, a lovely, unhurried start that tells guests the whole evening was thought through.
The Art of the Host
A heavy soup pot and an immersion blender are all this needs — the blender gives the soup its signature velvety texture right in the pot. Frozen sweet peas are ideal here; they're picked and frozen at peak sweetness, so the soup tastes of spring year-round. Let the soup cool slightly before blending if you use an upright blender, and never boil it after the cream goes in.
Neighborly Grace
- The Preparation: Deglaze the softened onions with sherry to build a concentrated base, simmer the peas and spinach until tender, then blend velvety-smooth and finish with a swirl of cream. Simmer long enough to break down the pea skins for the smoothest texture; it reheats well.
- The Pour: A crisp Sauvignon Blanc or a dry sparkling wine suits the fresh spring peas. For a non-alcoholic option, a mint-cucumber cooler or a sparkling lemon water keeps it garden-bright.
- The Vibe: This is vivid spring in a bowl — a brilliant green soup, served warm or chilled, that tastes like the season's first tender peas.
