Frequently Asked Questions

Yes, a tight lid traps heat and moisture. A loose lid lets heat escape, which ruins the texture of your meal.

Can I use my slow cooker stoneware in the oven?

Check your manual, but many stoneware pots are oven-safe. Never move a cold pot straight into a hot oven.

What is the benefit of a temperature probe?

A probe monitors the internal temperature of your meat. It ensures your roast hits the right doneness without drying out.

How do I prevent spills during transport?

Use a locking lid with a gasket seal. If you lack one, keep the unit upright to prevent leaks.

Programmable models are great for busy schedules. Manual ones are simpler, but they require you to be home.
