Before you start

Before beginning, ensure all ingredients are properly prepared and organized. Dice the carrots into uniform, bite-sized pieces to ensure they cook evenly. Mince the shallots finely so they meld into the sauce rather than remaining in large, distinct chunks.

If the monkfish is in a large fillet, trim away any tough membranes or silver skin and cut it into consistent, evenly sized chunks. Having everything prepped and ready to go before you start makes the assembly process fast and efficient, allowing you to get the slow cooker running in just a few minutes.

Ingredients at a glance (4)
  • 1 1/2 lb monkfish fillets, cut into chunks
  • 2 cups carrots, diced
  • 1/2 cup shallots, minced
  • 2 cups crushed tomato sauce

Instructions

Assembly of ingredients

  1. Assemble the base
    Place the monkfish chunks into the bottom of the slow cooker. Scatter the diced carrots evenly over the fish pieces to ensure they cook thoroughly.
    Look for The monkfish should be evenly spread across the bottom of the slow cooker surface.
    Tip Ensure the fish chunks are roughly the same size for even cooking.

At this phase, the slow cooker is filled with the raw monkfish, carrots, shallots, and tomato sauce. The ingredients are layered to ensure the fish is at the bottom. Check that all components are neatly arranged and that the sauce is distributed evenly over the top, ready for the slow cooking process to begin. The kitchen should be tidy and the slow cooker lid should be ready to be sealed tightly for the duration of the cooking time.

Slow cooking process

  1. Add aromatics and sauce
    Sprinkle the minced shallots over the carrots and fish. Pour the crushed tomato sauce over the top, making sure to cover all ingredients to keep the fish moist while cooking.
    Look for The tomato sauce should fully coat the fish and vegetables for optimal flavor infusion.
    Tip Do not stir the mixture, as the slow cooker will naturally combine the flavors during the cooking process.

During this phase, the slow cooker operates on low heat, allowing the ingredients to simmer gently. The kitchen will begin to fill with the savory aroma of the tomato sauce and shallots. Check that the slow cooker is set to the correct temperature and that the lid remains closed to trap the moisture. By the end of this phase, the vegetables should be tender, and the sauce should have reduced slightly, signaling that the dish is nearly finished.

Final check and serving

  1. Cook and serve
    Cover the slow cooker and cook on low for 4 hours. Ensure the monkfish reaches an internal temperature of 145°F (63°C) before serving to ensure it is cooked through safely.
    Look for The fish should be opaque and flake easily with a fork when the cooking time is complete.
    Safe temperature 145°F (63°C) internal temperature (fish)
    Tip Test the internal temperature in the thickest part of the fish chunk.

In this final stage, the monkfish is checked for the correct internal temperature of 145°F (63°C). The fish should be opaque and flaky. Ensure the sauce has reached a desirable, rich consistency.

Once these conditions are met, the dish is ready to be portioned onto plates. Check the seasoning one last time if necessary and serve immediately while steaming hot, ensuring the presentation highlights the beautiful colors of the fish and the vibrant tomato sauce.

Common mistakes

A common mistake is cutting the monkfish into uneven pieces, which leads to some parts being overcooked while others remain undercooked. Always aim for consistency in sizing. Avoid lifting the slow cooker lid frequently during the cooking process, as this releases heat and steam, significantly increasing the total cooking time and potentially drying out the fish.

Finally, do not overcook the fish; while the slow cooker is forgiving, monkfish can become tough if left on the heat for too long after it has reached the target temperature.

How to tell it’s done

The monkfish is perfectly cooked when it reaches an internal temperature of 145°F (63°C). At this stage, the fish will have turned from a translucent state to a solid, opaque white color. It should flake easily when tested with a fork, showing a firm yet tender texture.

The sauce should be thickened and glossy, clinging slightly to the fish and vegetables, indicating that the flavors have fully developed and the dish is ready to be plated and served immediately.
