And then, the real star — crispy shallots. Fried until golden and fragrant, they bring a delicate crunch and a burst of caramelized sweetness, much like Caramelizing Onions, that contrasts beautifully with the smooth, savory soup beneath.

Instant Pot Creamy Leek and Potato Soup with Crispy Shallots

Servings: 3 – 4

Skill level: Intermediate

Total time: 25 minutes

Calories: 295 kcal per serving

⸻

2 medium leeks (white & light green parts only), cleaned & sliced

1 medium yellow onion, chopped

2 tablespoons unsalted butter

2 tablespoon olive oil

3 medium Yukon Gold potatoes, unpeeled and diced

1 bay leaf

4 cups vegetable broth

1/2 cup heavy cream

Salt and black pepper, to taste

For garnishing: crispy shallots, drizzled shallot oil and cream.

For The Crispy Shallots

2 medium shallots, thinly sliced into rings

½ cup neutral oil (canola, grapeseed, or sunflower)

Pinch of salt

Slice the shallots as thinly and evenly as possible (use a mandoline if you have one). Pat them dry with a paper towel — this prevents splattering and ensures crispiness.

In a small skillet or saucepan, heat oil over medium-low heat. Add shallots before the oil gets too hot (they should slowly start to sizzle).

Stir occasionally, cooking for 6–8 minutes until golden brown. NOTE: Watch closely near the end — they can go from golden to burnt in seconds!

Use a slotted spoon to transfer shallots to a paper towel-lined plate. Immediately sprinkle with a pinch of salt. Save the flavorful shallot oil — it’s liquid gold! Drizzle it over the soup before serving.

Making The Soup

Sauté Aromatics

Turn the Instant Pot to Sauté mode.

Add butter and olive oil.

Stir in onion and leeks; cook 5–6 minutes until soft but not browned.

---

Cooks Notes

Keep stirring so they “sweat” gently — that’s how you extract their sweetness.

---

Stir in diced potatoes, salt, and pepper.

Add the bay leaf and pour in the vegetable broth, scraping the bottom of Instant Pot incert with a wooden spoon to release any fond (flavor bits).

Pressure Cook

Lock the lid, set the valve to Sealing, and cook on High Pressure for 7 minutes.

Allow 10 minutes for natural pressure release, then carefully quick release any remaining pressure.

Blend Until Silky

Use an immersion blender directly in the pot until the soup is smooth and velvety.

---

Safety tip: Turn off “Keep Warm” before blending to avoid splatter.

---

Finish With Cream and Adjust Seasoning

Stir in cream, taste, and add more salt or pepper if needed.

If it’s too thick, add a splash of broth to reach your desired consistency.

---

---

Serve and Garnish

Ladle into bowls and garnish with a swirl of cream, drizzled with the shallot oil followed by crispy shallots and a sprinkle of fresh or dried parsley.

---

Food Safety and Storage

Keeps 3 days in the fridge or up to 2 months frozen (omit cream before freezing).
