Before you start
Before starting, ensure your slow cooker insert is clean and dry. Prepare the turkey patties by shaping them into uniform, thick rounds if you are not using pre-formed ones.
Slice the mushrooms into consistent thicknesses, about 1/4 inch, to ensure they cook through evenly. Have all your ingredients measured and ready, as the assembly process is very fast and simple once you begin.
Ingredients at a glance (4)
- 5 ground turkey patties, thick and round
- 8 oz brown mushrooms, sliced
- 1 tbsp steak seasoning
- 1 cup steak sauce
Instructions
Assembly
- Layering the ingredientsPlace the ground turkey patties into the base of the slow cooker, ensuring they are arranged in an even layer. Scatter the sliced brown mushrooms over the top of the patties, covering them completely to ensure they cook down into the sauce.Look for The patties should be placed flat at the bottom of the slow cooker insert.Tip If the patties are too large, overlap them slightly to fit within the cooking area.
At the end of this phase, the turkey patties should be neatly arranged in the slow cooker with a generous layer of mushrooms on top. The ingredients should be ready to receive the seasoning and sauce, creating a compact base that will braise evenly. Ensure there is nothing obstructing the lid from closing securely before moving on to the next step of adding the liquids.
Seasoning
- Seasoning and saucingSprinkle the steak seasoning evenly over the mushroom and turkey layer. Pour the steak sauce directly over the top of the mushrooms and patties, ensuring everything is lightly coated. Cover the slow cooker with the lid to begin the cooking process.Look for The sauce should settle around the patties and mushrooms.Tip Use a spatula to gently nudge the sauce into the gaps if necessary.
Once the steak seasoning and steak sauce are added, the ingredients should look well-distributed. The sauce should be visible around the edges of the patties, and the mushrooms should be lightly coated.
At this point, the slow cooker is ready to be covered, and the cooking process can begin. Check that no ingredients are stuck to the sides of the ceramic insert where they might burn.
Cooking
- Slow cooking and servingCook on low for 4 hours until the turkey reaches an internal temperature of 165°F (74°C). Carefully remove the patties, letting them rest for 5 minutes before serving with the mushroom gravy spooned generously over the top.Look for The mushrooms should be tender and the sauce thickened.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Check the temperature using a meat thermometer inserted into the thickest part of the patty.
The dish is finished when the turkey is fully cooked, the mushrooms are tender, and the sauce has reduced slightly into a thick, flavorful gravy. The meat should be juicy and fragrant. Verify the internal temperature of the patties with a food thermometer, and ensure they are ready to rest before serving. The aroma should be savory, earthy, and distinctly steakhouse-inspired.
Common mistakes
A common mistake is overcrowding the slow cooker. Ensure the patties are arranged in a single layer to allow the heat to circulate properly. Another error is failing to check the internal temperature, as turkey can dry out if overcooked.
Be sure to avoid lifting the lid frequently during the cooking process, as this releases heat and moisture, which can significantly increase the required cooking time and affect the final tenderness of the patties.
How to tell it’s done
The turkey is done when the internal temperature reaches 165°F (74°C). The patties should feel firm to the touch and appear cooked through, with no pink remaining in the center.
The mushrooms should be soft and tender, having absorbed the steak sauce. Allow the patties to rest for 5 minutes after removing from the slow cooker to ensure the juices redistribute throughout the meat, resulting in a more succulent texture.
- Poultry: 165°F (74°C) in the thickest part
- Ground meat: 160°F (71°C) in the thickest part
