Before you start
Before beginning, ensure the monkfish is thoroughly cleaned and cut into even-sized medallions to promote uniform cooking. Verify that the button mushrooms are washed, dried, and quartered. Have the dry white wine and dried thyme measured and ready to go.
Confirm that the slow cooker is placed on a level, heat-resistant surface away from any water sources or flammable materials, and that you have a reliable digital meat thermometer on hand for checking the internal temperature of the fish.
Ingredients at a glance (4)
- 1 1/2 lb monkfish medallions
- 8 oz button mushrooms, quartered
- 1 tsp dried thyme
- 1/2 cup dry white wine
Instructions
Preparation and assembly
- Prepare the slow cookerPlace the raw monkfish medallions into the bottom of the slow cooker ceramic insert. Ensure the pieces are arranged in a single layer to allow for even cooking throughout the process.Look for The monkfish sits evenly on the bottom.Tip Pat the fish dry with paper towels before placing it in the cooker to remove excess surface moisture.
At this stage, the monkfish medallions are arranged neatly at the bottom of the slow cooker, topped with a layer of quartered mushrooms. The dry thyme and wine have been added, creating a flavorful foundation. Everything looks clean and organized, with the ingredients ready to start the gentle braising process once the lid is secured and the heat is activated.
Low heat braising
- Add aromatics and liquidScatter the quartered button mushrooms over the monkfish. Evenly sprinkle the dried thyme over the top of the mushrooms and fish, then pour the dry white wine over the entire mixture.Look for The wine moistens the fish and mushroom layer.Tip Distribute the mushrooms uniformly so they release their liquid across all the fish pieces.
During the cooking phase, the slow cooker maintains a steady, low temperature. You should notice the pleasant aroma of thyme and wine beginning to permeate the kitchen.
The mushrooms will soften and release their moisture, merging with the wine to create a light, savory broth that surrounds the fish. The fish remains submerged, ensuring it stays succulent throughout the entire process.
Completion and serving
- Slow cook and serveCover the slow cooker and cook on low for 3 hours. Check that the monkfish reaches an internal temperature of 145°F (63°C). Once cooked, transfer the fish and mushrooms to a warm plate and serve immediately while steaming.Look for The fish is opaque and flakes easily with a fork.Safe temperature 145°F (63°C) internal temperature (fish)Tip Use a digital thermometer to ensure the fish is cooked safely throughout without overcooking the delicate medallions.
Once the timer concludes, the monkfish should appear opaque, white, and tender. The mushrooms are tender and have infused the cooking liquid with their earthy essence. After verifying the internal temperature of 145°F (63°C), the dish is ready to be plated. The final result is a glossy, steaming assembly of perfectly cooked fish and aromatic vegetables ready for immediate enjoyment.
Common mistakes
A common mistake is overcrowding the slow cooker, which can lead to uneven cooking and excess liquid pooling, potentially boiling the fish rather than braising it. Always ensure the medallions are in a single layer.
Another error is using a sweet wine, which can overpower the delicate flavor of the monkfish; stick to dry varieties. Finally, avoid lifting the lid frequently during the cooking process, as this releases heat and moisture, significantly increasing the time required to reach the target temperature.
How to tell it’s done
The monkfish is considered done when it reaches an internal temperature of 145°F (63°C). At this stage, the flesh should be completely opaque, firm, and easily flake apart when pressed gently with a fork.
It should not be translucent or gelatinous in the center. Because monkfish has a dense structure, it is essential to check the thickest part of the medallions to ensure safety and quality before serving.
- Fish: 145°F (63°C) in the thickest part
