Helpful Tips for the Best Slow Cooker Kielbasa

• For a tangier sauce, add 1–2 teaspoons of extra mustard or a small splash of apple cider vinegar.

Storage and Reheating

Store leftover kielbasa and sauce in an airtight container in the refrigerator for up to 3–4 days. Reheat thoroughly in a saucepan over medium-low heat or in the microwave until steaming hot. Add a small splash of water if the sauce becomes too thick. Refrigerate leftovers within 2 hours of serving.
