Before you start

Before you begin, ensure your slow cooker is clean and placed on a stable, heat-resistant surface near an electrical outlet. Take the turkey tenderloins out of the refrigerator about 20 minutes before cooking to help them reach a more even temperature.

Have your measuring tools ready and ensure the parmesan cheese is finely grated so it melts evenly into the cream. Double-check that you have enough heavy cream on hand, as it is the foundation of the sauce.

Clearing your workspace will allow you to assemble the ingredients quickly and efficiently, keeping the process smooth.

Ingredients at a glance (4)
  • 2 lb turkey tenderloins
  • 1/2 cup grated parmesan cheese
  • 1 tbsp garlic herb seasoning
  • 1 cup heavy cream

Instructions

Assembly Phase

  1. Prepare the slow cooker
    Place the raw turkey tenderloins into the base of the slow cooker, ensuring they are arranged in a single layer to promote even cooking throughout the process.
    Look for The turkey should be laid flat at the bottom of the vessel.
    Tip Avoid overcrowding the slow cooker to ensure the heat circulates properly around the meat.

The turkey tenderloins should be arranged neatly at the bottom of the slow cooker. Everything is layered, but not yet cooked. The cream, cheese, and seasonings are added, and you are ready to begin the slow cooking process. Ensure the lid is firmly in place.

Cooking Phase

  1. Add aromatics and liquid
    Scatter the grated parmesan cheese evenly over the turkey, then sprinkle the garlic herb seasoning over the top. Pour the heavy cream carefully over the entire mixture to form the base of the sauce.
    Look for The cream should partially submerge the turkey and seasonings.
    Tip Ensure the seasoning is distributed across all pieces of meat for consistent flavor.

The turkey is cooking slowly in the cream and herb mixture. You may notice a slight aroma of garlic and herbs filling the kitchen. The sauce will begin to bubble very gently, and the cheese will start to incorporate into the cream, creating a smooth, rich base.

Finishing Phase

  1. Cook and serve
    Cover and cook on low for 4 hours until the turkey reaches an internal temperature of 165°F (74°C). Once cooked, remove the turkey carefully, let it rest for 5 minutes, then slice and serve with the warm cream sauce.
    Look for The sauce will be slightly thickened and the turkey will be opaque throughout.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Check the temperature at the thickest part of the tenderloin to ensure it is fully cooked.

The turkey is fully cooked, reaching the required 165°F (74°C). The sauce is thick, glossy, and fragrant. After resting the meat, it is ready to be sliced against the grain. The final dish should be steaming and ready for immediate service to your guests.

Common mistakes

A common mistake is overcooking the turkey, which can lead to a dry texture even in a slow cooker. Always monitor the cooking time and check the temperature once the time is up. Another error is failing to distribute the seasoning evenly, which results in pockets of intense flavor and areas that are bland.

Ensure you scatter the parmesan and herbs across the entire surface of the meat. Finally, do not lift the lid during the cooking process, as this releases heat and moisture, significantly increasing the time required.

How to tell it’s done

The turkey is perfectly cooked when it reaches an internal temperature of 165°F (74°C) as measured by a meat thermometer inserted into the thickest part of the tenderloin. The meat should be opaque and pull apart easily with a fork.

It is crucial to let the turkey rest for at least 5 minutes before slicing; this allows the juices to redistribute throughout the fibers, ensuring the meat remains moist and tender when served. The sauce should be glossy, creamy, and clinging slightly to the back of a spoon.

  • Poultry: 165°F (74°C) in the thickest part
