Slow Cooker Pierogie Casserole Recipe

Melt 3 tablespoons of butter in a large pot or Dutch oven over medium heat. Stir in the cabbage and onion. Cook and stir until the cabbage is tender about 20 minutes.

Place the bacon in a large deep skillet and cook over medium-high heat turning occasionally until evenly browned about 10 minutes. Drain the bacon slices on a paper towel-lined plate. Cut the bacon into bite-sized pieces; set aside.

Fill a large pot with lightly salted water and bring to a rolling boil over high heat. Once the water is boiling stir in the pierogies and return to a boil. Cook until the pierogies float to the top about 5 minutes; drain.

Place the remaining 3 tablespoons of butter into a slow cooker. Gently combine the pierogies cabbage and bacon; and place into the slow cooker. Cook on Low for 3 hours before serving.
