Before you start

Before beginning, ensure all ingredients are measured and ready to go. Chop the onion into uniform pieces to ensure they cook evenly. If you are using frozen shrimp, ensure they are completely thawed in the refrigerator overnight.

Prepare your serving dishes and have your rice cooked and ready, as this dish is best served immediately once the shrimp reaches the correct internal temperature. Clear your workspace to allow for easy assembly of the ingredients directly into the slow cooker vessel.

Ingredients at a glance (5)
  • 1 lb raw peeled shrimp
  • 1 large onion, chopped
  • 1/4 tsp yellow turmeric
  • 1 tsp ground ginger
  • 15 oz crushed canned tomatoes

Instructions

Layering the base

  1. Assemble ingredients
    Place the raw peeled shrimp in the bottom of the slow cooker. Scatter the chopped onions evenly over the shrimp to ensure balanced cooking throughout the process.
    Look for The shrimp are arranged in a single layer at the bottom.
    Tip Ensure the shrimp are completely thawed if using frozen to prevent excess water.

At the end of this phase, the shrimp and onions should be neatly arranged in the slow cooker. The ingredients should look fresh and ready for seasoning.

It is important that the onions are spread evenly over the shrimp to allow their juices to release and flavor the seafood throughout the long cooking process.

Seasoning and saucing

  1. Season and add liquid
    Sprinkle the yellow turmeric and ground ginger over the onions and shrimp. Pour the crushed canned tomatoes over the top to cover the ingredients, creating the base for the sauce.
    Look for The spices are distributed evenly and the tomatoes cover the mixture.
    Tip Use a spatula to gently spread the tomatoes if they clump together.

The slow cooker should now contain the shrimp, onions, spices, and tomatoes. The spices should be evenly distributed, and the tomatoes should provide a uniform layer over the other ingredients. Check that there is no dry spice left on the sides of the cooker, which could burn during the cooking cycle.

Cooking and finishing

  1. Slow cook and serve
    Cover the slow cooker and cook on low for 2 hours. Ensure the shrimp reach an internal temperature of 145°F (63°C) before serving. Serve hot over cooked rice.
    Look for The sauce is glossy and the shrimp are opaque and firm.
    Safe temperature 145°F (63°C) internal temperature (shellfish)
    Tip Check the internal temperature at the thickest part of the shrimp.

After the cook time, the dish will be steaming and fragrant. The sauce should have reduced slightly and appear glossy. The shrimp should be firm and opaque, and the onions should be soft and translucent. Before serving, verify the internal temperature to ensure the dish is safe and ready for the table.

Common mistakes

A common mistake is overcrowding the slow cooker, which can lead to uneven cooking and excess liquid. Ensure the shrimp are distributed in a single layer at the bottom. Another error is using frozen shrimp directly; always thaw them first to avoid a watery sauce.

Finally, do not lift the lid during the cooking process, as this releases heat and steam, significantly increasing the cooking time and potentially affecting the final texture of the dish.

How to tell it’s done

The shrimp are perfectly cooked when they are opaque, firm, and curled into a C-shape. Using a meat thermometer, ensure the thickest part of the shrimp reaches an internal temperature of 145°F (63°C).

The sauce should be glossy, slightly thickened, and fragrant. Avoid overcooking, as the shrimp can lose their texture if left in the slow cooker for too long after they have reached the target temperature.

  • Shellfish: 145°F (63°C) in the thickest part
