My daughter asked me why I always cook on low when high is faster. I didn’t have a good answer, so I looked into it.
Do They Reach Different Temperatures?
Both settings eventually bring food to about the same simmering temperature. High just gets there faster. Low takes longer to heat up and cooks more gently.
When to Use Low
- Tough cuts like pot roast, chuck and pork shoulder. The long, gentle cook melts the connective tissue and makes them tender.
- When you’ll be gone all day.
- Soups and stews that taste better with time.
When to Use High
- Lean meats like chicken breast, which can dry out with a long cook.
- When you’re short on time.
- Dips and quick dishes.
Switching a Recipe
A common rule of thumb many recipe writers use: about 2 hours on low equals roughly 1 hour on high. Every slow cooker is different, so check for doneness.
Frequently Asked Questions
Can I start on high and switch to low?
Yes. Many cooks do this to get the food heating faster.
Is warm a cooking setting?
No. Warm only keeps cooked food warm.
For tender roasts, low is your best friend.
