can you cook corned beef on high in slow cooker

No, it's generally not recommended to cook corned beef on high in a slow cooker. Most experts advise using the low setting for tender, pull-apart results, as high heat can boil the liquid and toughen the meat fibers.

Why Low is Preferred

Corned beef brisket needs gentle, slow cooking to break down collagen into juicy tenderness—typically 8-10 hours on low for a 4 lb cut. High settings boil the brine, tightening fibers and yielding chewy results, like overcooked pot roast. Some recipes allow high for 4-5 hours if time-crunched, but low always wins for texture.

Forum Perspectives

Reddit cooks debate this hotly: one user warns 7 hours on high overcooks a big brisket, suggesting checks every hour and rinses to cut salt. Others braise in ovens at 325°F for 3 hours as alternatives, noting slow cookers take ages to simmer from fridge-cold. Trendy 2026 posts echo: low-only for St. Patrick's Day classics.

"Never use the HIGH setting... High heat boils the cooking liquid and tightens the meat fibers, resulting in tough, chewy corned beef."

Quick Tips for Success

• Rinse the brisket and use its seasoning packet with broth or beer.
• Low for 8-10 hours : Fat-side up, cover with liquid halfway.
• Test doneness : Fork-tender? Shreds easily.

• Veggies separate : Roast cabbage/potatoes at 425°F to avoid mush.

• High hack: 4-5 hours max, but monitor closely.

Cooking Time Comparison

Setting| Time (4 lb brisket)| Texture Risk| Best For
---|---|---|---
Low| 8-10 hours 19| Tender, fall-apart| Perfectionists
High| 4-5 hours 37| Potentially tough 1| Rushed meals

TL;DR: Skip high—go low for melt-in-mouth corned beef every time.
