Before you start
Before beginning, ensure the slow cooker is clean and placed on a flat, heat-resistant surface. Take the turkey tenderloins out of the refrigerator about 20 minutes prior to cooking to take the chill off, though they should not be left out for more than 30 minutes.
Slice the Roma tomatoes into uniform rounds, about a quarter-inch thick, to ensure they soften evenly. Prepare the minced garlic and have the mozzarella slices ready to go, as assembly is quick and efficient once the process begins.

Instructions
Assembly of the Slow Cooker
- Prepare the Slow CookerPlace the turkey breast tenderloins side by side into the base of the slow cooker, ensuring they are arranged in an even layer to promote consistent cooking throughout the process.Look for The turkey should be neatly arranged in the bottom of the crock.Tip Ensure the turkey is completely thawed before starting to ensure even cooking.
- Layer the IngredientsArrange the sliced Roma tomatoes over the turkey in a single layer. Sprinkle the dried basil and minced garlic evenly over the top of the tomato layer to distribute the flavor.Look for The tomatoes should cover most of the turkey surface.Tip Use fresh garlic for the best aromatic result.
The turkey should be positioned in the slow cooker with the tomato rounds, basil, and garlic arranged evenly on top. Ensure the ingredients are well-distributed so that the flavors permeate the meat throughout the cooking process.
The setup should look organized and ready for the heating phase, with the tomatoes providing a base for the cheese to follow.
Cooking the Turkey
- Add Cheese and CookLay the fresh mozzarella slices over the tomatoes. Cover the slow cooker and cook on low for 4 hours until the turkey is fully cooked and reaches an internal temperature of 165°F (74°C).Look for The cheese should be melted and the turkey opaque throughout.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Avoid lifting the lid too often to maintain a steady internal temperature.
The mozzarella should be melted and the turkey tenderloins should be thoroughly cooked. The kitchen will smell aromatic from the garlic and basil. Check the internal temperature to ensure the turkey has reached 165°F (74°C). The tomatoes should be soft, having released their juices to form a light, flavorful sauce at the bottom of the slow cooker.
Resting and Serving
- Rest and ServeOnce cooked, remove the turkey tenderloins from the slow cooker and let them rest on a plate for 5 minutes before slicing. Serve with the juices and melted cheese from the slow cooker.Look for The turkey should be tender and hold its shape while slicing.Tip Letting the meat rest helps retain the natural juices.
The turkey should be resting on a plate, allowing the juices to settle. The meat should look moist and tender, with the melted mozzarella and softened tomatoes clinging to the surface. It is now ready to be sliced and served, ensuring that each portion includes a generous amount of the tomato and cheese topping for a complete, balanced flavor experience.
Common mistakes
Avoid adding extra liquid to the slow cooker, as the tomatoes will release enough juice to braise the turkey; excess liquid can make the dish watery and dilute the flavor.
Do not remove the lid during the cooking process, as this releases heat and moisture, significantly increasing the cooking time and potentially drying out the meat. Finally, do not skip the resting step after cooking, as slicing the turkey immediately causes the juices to escape, resulting in a drier final product.
How to tell it’s done
The turkey is done 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 appear opaque and white throughout, with no signs of pink.
When touched, the surface should feel firm yet tender. Allowing the turkey to rest for at least 5 minutes before slicing is crucial, as this period allows the internal juices to redistribute, ensuring the meat remains moist and tender upon serving.
