Pro Tips

• For easy cleanup and removal, create a foil “sling.” Lay two long pieces of foil in a crisscross pattern inside your slow cooker, leaving enough overhang to act as handles.
• Meal prep this recipe by cooking the sausage and dicing all the vegetables up to 2 days in advance. Store them in an airtight container in the refrigerator until you’re ready to assemble.
• Don’t be afraid to customize! Add a cup of fresh spinach, sautéed mushrooms, or swap the cheddar for a spicy pepper jack or creamy Monterey Jack cheese.
• To avoid a rubbery texture, check for doneness early. The casserole is ready when the edges are firm and the center is just barely set. It will continue to cook from residual heat.
