I Accidentally Made This Too Good. Now It’s the Only Thing Anyone Wants Me to Bring to Potluck.

Why This Dish Works

✅ Just 4 ingredients – Mostaccioli, marinara, mozzarella, Parmesan – that’s it

✅ No boiling pasta first – Goes in raw, cooks in the slow cooker

✅ Perfectly tender pasta – Holds its shape, not mushy

✅ Golden, stretchy cheese top – That glorious, bubbly crust

✅ Set it and forget it – 5 minutes of prep, then walk away

✅ Crowd-sized – Feeds a hungry potluck crowd
