This Slow Cooker Cowboy Casserole is a hearty and flavorful meal perfect for busy weeknights or potlucks. With tender ground beef, savory bacon, sweet corn, creamy cheese, and fluffy potatoes, this dump-and-go recipe is a guaranteed crowd-pleaser that the whole family will love.
For best results, don't overcook the potatoes; check for tenderness after 6 hours on low or 3 hours on high. The BBQ sauce is a key flavor component, so choose one you love. Layering ingredients ensures even cooking. Browning the ground beef adds a rich, savory flavor, so don't skip that step. Taste the casserole after a few hours and adjust seasoning as needed. Store leftovers in an airtight container in the refrigerator for up to 3 days. To freeze, let the casserole cool completely, transfer to a freezer-safe container, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
