Before you start
Before beginning, ensure your slow cooker insert is clean and dry. Gather all ingredients and measure the parmesan and seasonings. Since the turkey is lean, avoid overcooking it, as this can negatively affect the final texture.
Prepare your workspace by laying out a clean cutting board for any necessary trimming of the turkey tenderloins, though most store-bought versions are already trimmed and ready to use. Having your ingredients ready to go allows for a quick assembly, meaning the slow cooker can be switched on and left to work its magic without any further intervention.
Ingredients at a glance (6)
- 2 lb turkey breast tenderloins
- 10 oz fresh baby spinach
- 1 tsp garlic powder
- 1 tbsp Italian seasoning
- 10.5 oz condensed cream of chicken soup
- 1/2 cup grated parmesan cheese
Instructions
Turkey Preparation
- Prepare the turkeyPlace the turkey breast tenderloins into the base of the slow cooker, ensuring they are arranged in an even layer to promote consistent cooking throughout the meat.Look for Turkey should be arranged in a single layer.Tip Pat the turkey dry with paper towels before placing it in the cooker to improve browning.
At this phase, the turkey should be neatly arranged at the bottom of the slow cooker. Ensure the tenderloins are not overlapping too much, as this promotes even heat distribution.
A well-organized base ensures that the meat cooks uniformly, setting the stage for the flavorful sauce that will follow. Check that the slow cooker is on a stable, heat-resistant surface before adding the remaining ingredients.
Seasoning and Spinach
- Add aromatics and spinachPile the fresh baby spinach on top of the turkey tenderloins, then sprinkle the garlic powder and Italian seasoning evenly over the spinach to season the entire dish.Look for Spinach will appear wilted after cooking.Tip Adding the spinach on top allows it to steam perfectly in the confined space.
The spinach should be piled high on top of the turkey. While it looks like a large volume, it will reduce significantly during the cooking process. Sprinkling the garlic powder and Italian seasoning evenly over the spinach ensures that the aromatics are distributed throughout the dish as the spinach wilts and the sauce develops. The ingredients should look ready for the liquid component to be added.
Sauce Integration
- Combine and cookIn a separate mixing bowl, whisk together the condensed cream of chicken soup and the grated parmesan cheese until smooth, then pour the mixture over the turkey and spinach. Cover and cook on low for 4 hours until the internal temperature of the turkey reaches 165°F (74°C).Look for The sauce will be thick and bubbly, and the turkey opaque.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Ensure the sauce covers the turkey to keep it moist during the long cooking process.
The sauce mixture should be completely smooth after whisking the soup and parmesan together. Once poured over the turkey and spinach, it should coat the ingredients thoroughly. During cooking, the sauce will thicken and become fragrant. At the end of the phase, the turkey will be cooked through, the spinach will be tender, and the sauce will have a creamy, uniform consistency ready for serving.
Common mistakes
A common mistake is overcrowding the slow cooker or using pieces of turkey that are too small, which can lead to uneven cooking or a mushy texture. Additionally, adding the parmesan cheese directly to the slow cooker without whisking it into the soup first can result in clumpy sauce.
Avoid lifting the lid frequently during the cooking process, as this releases heat and significantly increases the total cooking time required for the turkey to reach the safe internal temperature.
How to tell it’s done
To determine when the turkey is perfectly cooked, use an instant-read meat thermometer inserted into the thickest part of the tenderloin. The turkey is ready when it reaches an internal temperature of 165°F (74°C).
At this stage, the meat should be opaque throughout, firm to the touch, and easily flaked with a fork. Let the turkey rest for at least 5 minutes before serving to allow the juices to redistribute, ensuring every slice remains moist and tender for the final plate presentation.
- Poultry: 165°F (74°C) in the thickest part
