Ingredients:
- 1.5 lbs Cremini (Baby Bella) mushrooms, cleaned and sliced
- 8 oz Shiitake mushrooms, stems removed and sliced
- 0.5 oz dried Porcini mushrooms, reconstituted in 1 cup hot water
- 4 tbsp unsalted butter
- 3 large shallots, finely minced
- 4 cloves garlic, smashed and minced
- 1 tbsp fresh thyme leaves
- 1 medium Yukon Gold potato (approx. 150g), peeled and diced
- 0.5 cup dry Sherry
- 4 cups low-sodium vegetable or chicken bone broth
- 0.75 cup heavy cream
- 1 tsp fresh lemon juice
- 0.5 tsp kosher salt
- 0.25 tsp freshly cracked black pepper
Instructions:
- Reconstitute the porcini. Place 0.5 oz dried porcini in a bowl with 1 cup hot water. Let soak for 15 minutes until soft and pliable.
- Prep the mushrooms. Clean the 1.5 lbs cremini and 8 oz shiitakes (remove shiitake stems). Slice them into even 1/4 inch pieces. Note: Uniform slices ensure they brown at the same rate.
- Sear in batches. Heat 2 tbsp butter in your pot over medium high heat. Add half the mushrooms and cook for 8 minutes until they release their water and turn a deep mahogany brown. Remove and repeat with the second half.
- Sauté the aromatics. Lower heat to medium, add remaining butter, 3 minced shallots, and 4 minced garlic cloves. Cook for 3 minutes until fragrant and translucent.
- Deglaze the pan. Pour in 0.5 cup dry sherry. Use a wooden spoon to scrape up all the brown bits (fond) from the bottom until the liquid has reduced by half.
- Build the base. Add the seared mushrooms back to the pot. Stir in the diced Yukon Gold potato, fresh thyme, the strained porcini soaking liquid, and 4 cups broth.
- Simmer to soften. Bring to a boil, then reduce heat and simmer for 20 minutes until the potato cubes are tender enough to smash with a fork.
- Blend the bisque. Use an immersion blender to process the soup until completely smooth and velvety. If using a traditional blender, work in small batches and hold the lid down with a towel.
- Finish with richness. Stir in 0.75 cup heavy cream and 1 tsp lemon juice. Heat through for 2 minutes until small bubbles appear around the edges.
- Season and serve. Taste and add 0.5 tsp salt and 0.25 tsp pepper. Adjust salt as needed depending on your broth.
