Potato Soup with Parsnip & Mushroom

Potato Soup with Parsnip and Mushroom is a chunky, country-style bowl that earns its depth before any liquid hits the pot. Potatoes, parsnips, carrots, celery, and onions cook in a generous puddle of butter until lightly browned. That browning step is what separates this from a watery stovetop potato soup. The vegetables shift from raw to caramelized at the edges, building a base of toasty, sweet flavor.

Flour gets sprinkled over the lot and stirred to coat, which lets the soup thicken just enough to feel rich without going gloppy. Then chicken broth, marjoram, and chopped mushrooms join, and a low simmer pulls everything together for 25 minutes. Marjoram is the herb that makes this distinct, more delicate than thyme, with floral notes that play into the parsnip’s sweetness.

Pro Tips

• Parboil the potatoes for 6 to 8 minutes before peeling and dicing. They peel cleanly and hold their shape better in the soup.
• Brown the vegetables uncovered, with patience. Crowding the pot or covering it traps steam and you’ll boil instead of brown.
• Use cremini or chestnut mushrooms in place of plain white button. Browner caps deliver deeper savory flavor.
• Don’t skip the marjoram. It’s the herb the original recipe was built around. Fresh parsley at serving adds color, but marjoram is what gives the soup its character.

Variations

• Add a splash of cream or a dollop of sour cream at the end for a richer bowl.
• Stir in cooked diced ham or crumbled bacon for a heartier main-dish soup.
• Puree half the soup and stir back in for a creamier texture without losing the chunks.
