Rosemary Mushroom Soup Recipe

Rosemary Mushroom Soup Recipe

Prep Time 45 minutes
Total Time 45 minutes
Servings 4 to 6


  • 4 tablespoons olive oil divided
  • 1-1/4 cup roughly chopped brown onion about 1 small onion
  • 4 small to medium-sized roughly chopped garlic cloves
  • 2 tablespoons finely chopped fresh rosemary
  • 2 pounds washed & dried crimini mushrooms divided
  • 1/3 cup cream sherry
  • 1-1/4 cup peeled & roughly chopped yukon gold potato
  • 4 cups vegetable stock
  • Sea salt and freshly ground pepper to taste


  1. Roughly chop three-fourths of the mushrooms, and thinly slice the remaining fourth. Set them aside in separate bowls.
  2. Coat the bottom of a large sauce pan with 1-1/2 tablespoons of olive oil and place it over medium-low heat.
  3. Add the onion and garlic and cook until the onions are soft and translucent, about 5 minutes.
  4. Add the rosemary, stir, and let it heat until it's aromatic, about 30 seconds.
  5. Turn the heat to high, add another 1-1/2 tablespoons of the olive oil and half of the roughly chopped mushrooms. Cook until they shrink down a bit, about 5 minutes. Then add the remaining roughly chopped mushrooms and cook until any liquid that comes out of the mushrooms has completely evaporated and the mushrooms are golden brown, about 15 minutes.
  6. Turn the heat to low, add the sherry and stir. Turn the heat back to high and cook until all but about 2 tablespoons or so has evaporated. This should only take a couple of minutes.
  7. Turn the heat down to medium and stir in the potatoes. Cook for a couple of minutes and then pour in the stock.
  8. Bring to a boil, then reduce the heat to low, cover and simmer until the potatoes are tender, about 15 minutes.
  9. While the soup is simmering, heat a medium-sized sauté pan with the remaining tablespoon of olive oil. Turn the heat to high and add the thinly sliced mushrooms. Sauté until they are nicely browned on both sides, about 10 minutes. Season to taste with salt and pepper. Set aside.
  10. Use an immersion or standing blender to puree the soup until it's as smooth as possible. (It will not get 100% smooth.)
  11. Then add in the sautéed mushrooms and season to taste with salt and pepper.

Recipe Notes

If you use a standing blender for hot liquids, you have to hold down the lid very, very firmly! If you don't do this, the hot liquid, the vibration, and the steam will force the lid off -- be careful!

Don't know exactly what "season to taste" means? Here's the answer.
