Sweat Leeks: Heat up Instant Pot using Sauté More function. Wait until it says HOT (~8 mins). Add 2 tbsp (28g) unsalted butter and chopped leeks in Instant Pot. Season with a pinch of salt, then cook leeks until softened (~4 mins). Once the leeks are softened, add in 2 bay leaves, 1 tsp (1.5g) dried thyme, and minced garlic. Saute for another 30 seconds.
Pressure Cook Potato Leek Soup: Pour in 4 cups (1L) unsalted chicken stock, 2 tbsp (30ml) fish sauce (or sub with regular soy sauce), and diced potatoes. Give everything a quick mix. Pressure cook at High Pressure for 5 minutes + 15 minutes Natural Release.
Season & Thicken: Add in 1 cup (250m) heavy cream. *Note: Some enjoy the potato leek soup without blending. Since we like a thicker soup, we blend the potato leek soup at this step with an Immersion Hand Blender. Taste and season with more salt if desired (for reference, we added 2 large pinches of salt at the end to season this properly).
Serve Leek Potato Soup: Garnish with finely sliced green onions, bacon bits, fried leeks, or fresh herbs. Season with some freshly ground black pepper. Serve immediately. Enjoy!~ 🙂
