Ingredients
Main
- 2 lb turkey tenderloins
Sauce
- 1/2 cup grated parmesan cheese
- 1 tbsp garlic herb seasoning
- 1 cup heavy cream
Why this recipe works
The slow cooking method is ideal for turkey tenderloins because it maintains moisture in a lean cut of meat. By cooking the poultry in a bath of heavy cream, the fibers remain tender and juicy throughout the process, preventing the dryness often associated with lean white meat. The gentle heat allows the garlic herb seasoning and parmesan cheese to fully infuse the turkey, creating a cohesive and savory profile that penetrates deep into the meat during the long, steady cook time.
Furthermore, the cream-based sauce benefits from the low and slow heat, as it reduces slightly and thickens without breaking. The parmesan cheese melts into the liquid, providing a natural thickening agent and a salty, umami-rich finish that coats the turkey perfectly upon serving.
This method ensures that the sauce is not just a topping, but an integral part of the dish, resulting in a restaurant-quality texture that is achieved with very little hands-on preparation or technical skill required.
Notes and substitutions
When selecting turkey tenderloins, look for pieces that are relatively uniform in thickness to ensure they cook at the same rate. If you find significant size discrepancies, you may trim the ends slightly to create a more consistent shape.
It is important to use high-quality grated parmesan for the best flavor, as the cheese is a primary component of the sauce. Avoid using pre-shredded cheese with anti-caking agents if possible, as it may not melt into the cream as smoothly as freshly grated options.
Regarding equipment, this recipe works best in a standard oval slow cooker. If you have a programmable model, you can set it to the low setting and let it run for the required time without worry. Ensure your slow cooker insert is clean before starting.
If you prefer a thicker sauce, you may whisk the juices with a small amount of cornstarch slurry after removing the turkey, though the natural reduction of the cream and parmesan is typically sufficient for a luxurious, velvety consistency.
- Heavy cream: Half-and-half or full-fat coconut milk can be used, though the final sauce will be less rich and velvety.
- Garlic herb seasoning: A mixture of dried garlic powder, dried parsley, and a pinch of dried oregano or basil.
