Ingredients

• 1 lb (450g) Raw Shrimp, peeled and deveined
• 3 Tbsp Unsalted Butter, divided
• 1 Medium Onion, minced
• 2 Medium Carrots, minced
• 2 Celery Ribs, diced
• 3 Medium Potatoes, diced (about 1.5 lbs total)
• 2 cloves Garlic, minced
• 4 cups Chicken Stock or Vegetable Stock
• 1 Bay Leaf
• ½ tsp Paprika
• ½ tsp Dried Thyme
• ¼ cup Cream Cheese, softened
• ¼ cup Heavy Cream
• Optional Spices: ½ tsp Cayenne Pepper, ½ tsp Old Bay Seasoning
• For Garnish: Grated Parmesan Cheese and Fresh Parsley

Instructions (Instant Pot Method)

1. Sauté Shrimp (Crucial Step): Set the Instant Pot to Sauté mode. Add 1 tablespoon of butter. Once melted, cook the shrimp on both sides for 2–3 minutes until they just turn opaque. Transfer the shrimp to a shallow plate and set aside. Do not rinse the pot.
2. Sauté Vegetables: Add the remaining 2 tablespoons of butter to the pot. Cook the onions, carrots, and celery for 3 minutes. Add the garlic and diced potatoes and cook for 1 minute more.
3. Pressure Cook: Stir in the paprika, thyme, bay leaf, and any optional spices. Add the chicken stock and the cubed, softened cream cheese. Close the lid and set the vent to the Sealing position. Select Manual/Pressure Cook on High for 2 minutes.
4. Release and Finish Sauce: Once the time is up, do a Quick Release (QR) to vent the pressure. Carefully remove the lid. Add the heavy cream and stir until the cream cheese is fully incorporated and the sauce is smooth.
5. Add Shrimp and Serve: Stir in the reserved cooked shrimp. Use the Reheat function (or low Sauté) for 1–2 minutes to warm the shrimp through. Adjust seasoning to preference. Serve immediately, topped with Parmesan and fresh parsley.

Stovetop Method

1. Sauté & Simmer: Sauté the vegetables and spices in a pot with butter. Add the potatoes, stock, and cream cheese. Bring to a boil, then reduce heat and simmer for 20 minutes, or until the potatoes are tender.
2. Finish: Stir in the cooked shrimp and heavy cream at the very end.

Storage and Expert Tips

• Don’t Overcook the Shrimp: The key to this instant pot shrimp and potato recipe is reserving the shrimp. Shrimp cooks very quickly, and pressure cooking it for 2 minutes will turn it rubbery.
• Roux-Free Thickening: The combination of starch released by the pressure-cooked potatoes and the stability of the cream cheese creates a thick, flavorful base without the need for flour or cornstarch.
• Spice is Key: A pinch of cayenne or Old Bay seasoning adds necessary depth to the creamy shrimp chowder and helps balance the richness of the dairy.
• Dairy Management: Ensure the cream cheese is added in small, softened cubes before pressure cooking. The heavy cream is always added after the pressure release.

Variations

• Low-Carb: Substitute the diced potatoes with diced radishes (they soften like potatoes) or skip them and add a cup of riced cauliflower at the end.
• Smoked Flavor: Add 4 ounces of chopped, pre-cooked ham or bacon along with the vegetables (Step 2).
• Tomato Base: Add a small can of diced tomatoes (drained) with the stock for a touch of acidity and color.

Frequently Asked Questions

Q: Can I use frozen shrimp directly in the Instant Pot? A: No, you must thaw the shrimp first. If you skip the initial sauté (Step 1), the shrimp will not contribute its flavorful fond (browned bits) to the pot. If using frozen, thaw them completely, pat them dry, and then sauté as directed.

Q: Why does this creamy shrimp chowder recipe use a 2-minute pressure cook time? A: A 2-minute high pressure cook is the bare minimum needed to break down the starch in the potatoes and carrots quickly, ensuring they are perfectly tender and ready for blending into a smooth chowder base.

Q: How do I prevent the cream cheese from getting stuck to the bottom and burning? A: Solution: Ensure the cream cheese is placed on top of the potatoes, not directly on the bottom of the liner. The liquid (stock) must be poured in first, and the cream cheese should be added in small, softened cubes.

Q: How do I store and reheat this instant pot creamy shrimp soup? A: Store leftovers in an airtight container for up to 3 days in the refrigerator. Reheat gently on the stovetop over low heat, adding a splash of broth or water if the soup has thickened considerably when cold.
