Why you’ll love it

- Scallions add freshness without extra prep time.
Ingredients
Ingredient amounts scale. Oven temperature and cook time do not. Salt, spices, and leaveners are a starting point after you scale. Taste and adjust.
Check the ingredients you still need, then add them. If nothing is checked, the full list is added. Saved on this device.
Instructions
- 1
Toss sliced steak with cornstarch until lightly coated; shake off excess.

Heat 2 tbsp oil in a large skillet over high heat and sear beef in a single layer 1 to 2 minutes per side; work in batches and set aside.
- 3
Lower heat to medium, add remaining oil, garlic, and ginger; cook 30 seconds.
- 4
Stir in soy sauce, brown sugar, water, and red pepper flakes; simmer 2 to 3 minutes until slightly thick.
- 5
Return beef and green onions to the skillet and toss 1 minute to coat.
- 6

Kitchen tools we love
Practical tools these recipes actually use. This is not a review roundup, and these are not paid placements. If affiliate links are added later, they will be labeled and disclosed.
A heavy 12-inch skillet
Most of the chicken and steak recipes are written for one pan that holds heat. Stainless or cast iron both work.
An air fryer with a real basket
The air-fryer recipes expect a single layer. A crowded basket steams instead of browning.
A half-sheet pan
Drumsticks, potatoes, sausage, and carrots all use one. A dark pan browns faster than a very shiny one.
A sharp chef’s knife
These recipes do not need a specialty blade. A sharp 8-inch knife is faster and safer than a dull one.
A large cutting board
Big enough that the onion and the raw chicken are not sharing the same puddle.
Dry cups and a liquid cup
Desserts in particular expect level dry measures and a separate cup for milk.
An instant-read thermometer
Use it for poultry, pork chops, and meatloaf. Color is a weak guide.
