This soup brings together the best parts of a classic potato chowder and a simple shrimp dinner. The potatoes become tender in the pressure cooker, the vegetables create a savory foundation, and the shrimp add a sweet, delicate seafood flavor without requiring a long cooking time.
It is also an excellent weeknight meal because the Instant Pot handles the longest part of the process. While the potatoes cook, you can prepare a salad, warm bread, or set the table.
The soup is flexible enough for different preferences. Seafood stock gives it a stronger ocean flavor, chicken broth is a familiar pantry choice, and vegetable broth works well when you want a lighter-tasting base.

Ingredients You’ll Need
Start with Yukon Gold or russet potatoes cut into evenly sized 3/4- to 1-inch cubes. Yukon Gold potatoes have a naturally buttery texture, while russets break down more readily and can help make the broth thicker.
Onion, celery, and garlic provide the aromatic base. Dice the onion and celery fairly small so they soften quickly during the Sauté stage and distribute throughout every spoonful.
Choose raw medium or large shrimp that have been peeled, deveined, and stripped of their tails. Fresh or thawed shrimp both work, but pat them dry before adding them so excess water does not dilute the soup.
- Use low-sodium broth so you can control the final seasoning.
- Choose half-and-half for a lighter creamy soup or heavy cream for a richer chowder.
- Add Old Bay for a classic shrimp-seasoned taste, or leave it out for a milder herb profile.
- Keep fresh parsley or chives ready for a bright finish.

How to Make It Step-by-Step
Step 1: Begin by setting the Instant Pot to Sauté and adding the butter or olive oil. Cook the onion and celery for about 3 to 4 minutes, stirring now and then, until they look glossy and softened. Add the garlic during the final 30 seconds so it becomes fragrant without burning.
Step 2: Pour in the broth and immediately scrape the base of the pot with a wooden spoon. This step removes stuck-on bits and helps prevent a burn warning during pressure cooking. Add the cubed potatoes, salt, pepper, thyme, and Old Bay if using.
Step 3: Secure the lid and set the cooker to High Pressure for 6 minutes if your potato pieces are about 3/4 inch. Use 8 minutes for larger cubes, since they need additional time to soften completely.
Step 4: Let the pressure release naturally for 5 minutes after cooking ends. Carefully release the remaining pressure, keeping your face and hands away from the steam, then remove the lid once the pin drops.
Step 5: Switch the pot to Sauté or Keep Warm and stir in the half-and-half or heavy cream. The dairy belongs at the end because pressure cooking it can affect its texture and may increase the chance of scorching.
Step 6: Add the raw shrimp and cook gently for approximately 3 to 5 minutes. Stir occasionally and watch for the visual cues: properly cooked shrimp turn pink, opaque, and gently curled. Remove the pot from high heat as soon as they are done.
Step 7: Adjust the consistency if needed. Mash about 1 cup of cooked potatoes against the inside wall of the pot for a naturally creamy broth, or stir in a slurry made from 2 tablespoons cornstarch and 3 tablespoons cold water, then simmer for 1 to 2 minutes.
Step 8: Taste the finished soup and correct the salt and pepper. Sprinkle in the parsley or chives just before ladling the soup into bowls.
Pro Tips for the Best Soup
Even potato pieces are one of the most important details in this recipe. If some cubes are small and others are large, the smaller pieces may dissolve before the larger ones are tender. Aim for a consistent 3/4- to 1-inch cut.
Always scrape the pot after adding the broth, especially if the butter or oil has picked up browned vegetable bits. A clean cooking surface reduces the chance of a burn notice and leaves the broth tasting fresh.
Add the shrimp only after pressure cooking. Shrimp need just a few minutes in the hot soup, and pressure-cooking them with the potatoes can make them firm and rubbery.
For the smoothest dairy finish, stir the cream in gradually. Avoid bringing the soup to a hard boil after adding it; gentle heat is enough to warm the broth and cook the shrimp.
Bacon is an optional variation if you want a smoky chowder. Sauté 3 to 4 slices first, remove them before cooking the vegetables, and crumble them over the bowls at serving time.
Corn is another popular addition. Stir in 1 to 2 cups of frozen or canned corn with the cream and shrimp, allowing it to warm through during the final cooking stage.
What to Serve with Creamy Shrimp Soup
A bowl of this soup can stand alone, but a crisp side makes the meal feel complete. Serve it with crusty sourdough, oyster crackers, garlic toast, or a simple green salad.
A cool side can balance the warm, creamy broth, especially in spring or summer. Our creamy cucumber tomato salad adds fresh vegetables and a refreshing contrast.
For a larger family meal, offer sliced bread and a small platter of fruit. Keep the toppings simple so the shrimp, herbs, and tender potatoes remain the main attraction.
This recipe also fits nicely into a soup-and-salad dinner rotation. If you like variety, try our easy tortellini soup on another night for a pasta-filled comfort meal.
Storage, Reheating, and Make-Ahead Notes
Cool leftover soup promptly and transfer it to a covered container. Store it in the refrigerator for up to 3 days, keeping in mind that the potatoes may absorb some broth as they sit.
Reheat individual portions in the microwave in short intervals, stirring between each one. You can also reheat the soup in a saucepan over low to medium heat, but avoid a vigorous boil because the cream may separate and the shrimp can overcook.
If you are planning ahead, pressure-cook the potato and broth mixture earlier in the day, then add the dairy and shrimp shortly before serving. This keeps the shrimp at its best and makes the final step quick.

Ingredients
Method
- Set a 6-quart Instant Pot to Sauté. Add the butter or olive oil, then cook the diced onion and celery for 3 to 4 minutes, stirring occasionally, until softened. Add the minced garlic and cook for 30 seconds.
- Pour in the broth and scrape the bottom of the pot thoroughly to remove any browned bits. Add the potatoes, kosher salt, black pepper, dried thyme, and optional Old Bay seasoning.
- Lock the lid and set the Instant Pot to High Pressure for 6 minutes when using 3/4-inch potato cubes, or 8 minutes for larger cubes. When the cooking time ends, allow a 5-minute natural release, then carefully release the remaining pressure.
- Switch the pot to Sauté or use Keep Warm, then stir in the half-and-half or heavy cream. Add the raw shrimp and gently cook for 3 to 5 minutes, stirring occasionally, until the shrimp are pink, opaque, and just cooked through.
- For a thicker soup, mash about 1 cup of potatoes against the side of the pot. Alternatively, whisk the cornstarch with cold water, stir the slurry into the soup, and simmer for 1 to 2 minutes.
- Taste the soup and adjust the salt and pepper. Stir in the chopped parsley or chives and serve immediately while the broth is hot and creamy.
