Tips
Do not stir during the long cooking phase; this allows beef to braise evenly and develop deep flavor without drying out.
Add broccoli slaw near the end to preserve its crisp texture and bright color; prolonged cooking will turn it mushy.
For extra depth, sear beef pieces in a hot pan before adding to slow cooker, then deglaze the pan with a splash of broth to capture browned bits.
Good to Know
Refrigerate in airtight container up to 4 days. Freeze up to 3 months; thaw overnight before reheating.
Prepare ingredients (chop onion, cut beef) up to 1 day ahead and refrigerate separately. Assemble slow cooker in the morning for evening cook.
Ladle into bowls and serve hot. Offer crusty bread or crackers alongside. Garnish with fresh parsley or additional herbs if desired.
Common Mistakes
Stir during cooking to avoid uneven texture; beef becomes tough and broccoli slaw turns mushy.
Add broccoli slaw at the start to avoid overcooking and losing color and crispness.
Skip the standing time to avoid forgetting peas or uneven temperature distribution.

Full guide →FAQ
Can I use a pressure cooker instead of a slow cooker?
Yes. Cut beef into 1-inch pieces. Cook on high pressure 15 minutes, then quick-release. Add broccoli slaw and potatoes, cook 3 more minutes on high pressure, quick-release, then add peas and let stand 5 minutes.
What if I do not have broccoli slaw?
Substitute shredded cabbage, fresh spinach, or kale in equal amounts. Add tender greens near the end of cooking to preserve texture. Cooking time may be slightly shorter for tender greens.
How long can I keep leftovers and can I freeze this soup?
Store refrigerated in airtight containers up to 4 days. Freeze up to 3 months in freezer bags or containers. Thaw overnight in the refrigerator and reheat gently on the stovetop or in the microwave until hot.
