Before you start
Before starting, ensure your slow cooker insert is clean and placed on a stable surface. Drain and rinse the canned black beans thoroughly under cold running water to remove excess sodium and starch.
Measure out all your ingredients so that assembly is quick and efficient. If you choose to use frozen corn, there is no need to thaw it beforehand, as the slow cooker will heat it through perfectly during the long cooking cycle.
Ingredients at a glance (5)
- 1 1/2 lb whole turkey tenderloins
- 1 can (15 oz) black beans, rinsed and drained
- 1 cup corn kernels
- 1 tbsp chili powder
- 1 cup chunky salsa
Instructions
Preparation and assembly
- Prepare the slow cookerPlace the turkey tenderloins into the slow cooker insert, arranging them in a single layer to ensure even cooking throughout the process.Look for The turkey should fit snugly in the bottom of the slow cooker insert without being overcrowded.Tip If the tenderloins are very long, cut them in half to fit the insert better.
- Add aromatics and beansScatter the black beans and corn over the turkey. Sprinkle the chili powder evenly across the top, then spoon the chunky salsa over everything to coat.Look for The salsa should cover the surface of the turkey and vegetables to create a moist cooking environment.Tip Spread the salsa evenly to ensure every piece of turkey gets seasoned.
At this phase, the slow cooker contains the raw turkey, beans, corn, and seasonings. Everything should be arranged neatly to promote even heating. The smell should be fresh and the ingredients should look vibrant, with the salsa coating the top of the turkey tenderloins thoroughly before you secure the lid.
Slow cooking cycle
- Slow cook the turkeyCover the slow cooker with its lid and cook on low for 4 hours. Ensure the internal temperature of the turkey reaches 165°F (74°C) using a food thermometer.Look for The turkey is ready when it is tender and the internal temperature reaches 165°F (74°C).Safe temperature 165°F (74°C) internal temperature (poultry)Tip Avoid lifting the lid frequently, as this releases heat and increases the required cooking time.
During the cooking phase, the slow cooker will emit a savory, spiced aroma. The turkey will gradually turn from pink to opaque as it braises. Check that the lid remains sealed. By the end of this phase, the turkey should look tender and the beans should be soft and fully integrated with the salsa.
Resting and serving
- Rest and serveRemove the turkey from the slow cooker and let it rest on a cutting board for at least 5 minutes before slicing or serving alongside the beans and corn.Look for The turkey should look moist and tender, with the salsa having reduced slightly into a thick, flavorful sauce.Tip Resting allows the juices to redistribute throughout the meat, keeping it tender.
Once finished, the turkey should look succulent and moist. After resting for five minutes, the meat will be ready to slice.
The final dish should feature a clear, appetizing presentation where the turkey sits amidst the warm bean and corn mixture, with the salsa sauce pooled appetizingly around the ingredients.
Common mistakes
Avoid overcooking the turkey, which can lead to a dry, stringy texture even in a slow cooker environment. While slow cookers are forgiving, exceeding the recommended cooking time by too much will eventually break down the meat fibers excessively.
Another mistake is failing to rinse the beans, which can result in a cloudy or overly salty sauce; always give them a quick rinse to keep the final flavors clean and vibrant.
How to tell it’s done
The turkey is perfectly cooked when the internal temperature, measured with a food thermometer at the thickest part of the tenderloin, reaches 165°F (74°C).
The meat should be opaque throughout and easily pull apart with a fork, showing a soft, braised texture. The salsa and vegetable mixture should be hot and slightly thickened, coating the meat beautifully without being overly watery.
