Method
Preparation
- Heat a large, heavy-bottomed pot over medium heat and add the butter.
- When the butter foams and begins to smell warm and nutty, add the diced onion. Sauté until translucent and fragrant, about 5 minutes.
- Stir in the garlic, carrots, and celery. Cook until the carrots soften and the kitchen smells sweet and herbal, about 4–6 minutes.
- Add the cubed potatoes and pour in the broth. Bring to a gentle boil, then reduce to a simmer. Add thyme, a pinch of salt, and pepper.
Cooking
- Simmer until the potatoes are tender when prodded with a fork, about 12–15 minutes.
- Stir in the peas and asparagus tips and simmer for another 3–4 minutes until the greens are bright and just tender.
- Reduce heat to low. Stir in the cream and lemon zest, warming gently — do not boil to avoid curdling.
- Taste and adjust salt and pepper.
- For a silky texture, use an immersion blender to purée about one-third of the soup or transfer a cupful to a blender, purée, and return.
- Whisk in the lemon juice and fold in fresh herbs. If adding protein, stir in shredded chicken or drained, rinsed white beans now and heat through.
Serving
- Serve hot with a drizzle of olive oil or a pat of butter, extra herbs, and a crack of black pepper.
Notes
Storage: Refrigerate in an airtight container for up to 4 days. Freeze in portions for up to 3 months; thaw overnight in the refrigerator. Reheat gently on the stovetop over low heat, adding a splash of broth or water if the soup has thickened.
