Before You Begin
Prepare your slow cooker and ingredients as needed. Cooking times and results may vary depending on your equipment and ingredients.
Prepare Cooker
Lightly grease the inside of the slow cooker with butter or nonstick spray.
Mix Liquid Base
In a bowl, whisk milk, melted butter, eggs, salt, pepper, and optional seasonings until fully combined.
Combine Ingredients
Add uncooked macaroni and shredded cheese to the slow cooker. Pour milk mixture evenly over the top. Stir gently to coat.
Cook
Cover and cook on LOW for 2–3 hours, stirring once or twice during cooking, until pasta is tender and sauce is smooth.
Finish
Turn off heat and stir gently. Let rest 5–10 minutes so sauce thickens naturally.
Serve
Serve warm. Add additional cheese during the last 20–30 minutes if desired.
