Instructions

Prepare the cooker by spraying the insert with cooking oil to prevent sticking.
Add the sliced steak and cornstarch to the cooker - toss to coat.
Top with the sliced onions.
Whisk the garlic, ginger, sesame oil, soy sauce, brown sugar, water, and black pepper together in a small bowl. Pour the mixture over the meat and onions.
Cover and cook on low for 6-8 hours (or on high for 3-4 hours). The beef should be cooked through and tender.
Stir in the green onions and dried chilis.
Garnish with sesame seeds before serving.

Notes

This recipe can be made with sirloin steak, skirt steak, flat iron steak, or chuck. Be sure to slice against the grain and cut into thin strips no more than ½-inch thick.

For the best results, cook low and slow for really tender meat.

All slow cookers heat differently.

For more texture to the onions, you can add them halfway through the cooking time so they are less tender when serving.

For more kick, add the dried chili peppers at the start of cooking so the flavors meld together. OR try using ground cayenne pepper, red pepper flakes, chili crisp oil, or even sriracha.

STORING

Refrigerate any leftovers in an airtight container for up to 4 days.
