1. Layer in Slow Cooker
Spread marinara sauce in the bottom of the slow cooker.
Add uncooked pasta, gently pressing down to submerge in sauce.
Dollop ricotta evenly over top (don’t stir!).
Sprinkle 2½ cups mozzarella over ricotta.
Reserve ½ cup mozzarella for finishing.
2. Cook Low & Slow
Cover and cook on LOW for 2.5–3 hours (or HIGH for 1.5–2 hours).
Pasta should be tender; sauce bubbly.
Do not lift lid early—steam is essential for cooking pasta.
3. Finish & Serve
Sprinkle reserved ½ cup mozzarella on top.
Cover and cook 10–15 minutes more until melted and golden.
Let rest 10 minutes before serving (helps it set).
