Prep the Steak:
Pat steak cubes dry and season with salt and pepper.
Sear the Steak Bites:
Heat olive oil in a large skillet over medium-high heat. Add steak bites in a single layer (cook in batches if needed). Sear for 1–2 minutes per side until browned but still juicy inside. Remove from skillet and set aside.
Make the Honey Garlic Sauce:
Reduce heat to medium. Add garlic to the same pan and sauté for 30 seconds until fragrant. Stir in honey, soy sauce, and vinegar. Simmer for 1–2 minutes.
Optional Thickening:
For a thicker glaze, mix water with cornstarch in a small bowl and stir into the sauce. Simmer another 1–2 minutes until thickened.
Toss Steak in Sauce:
Return steak bites to the pan and toss to coat in the glaze. Heat through for another minute.
Serve:
Garnish with parsley, green onions, or red pepper flakes. Serve hot with rice, mashed potatoes, or over stir-fried vegetables.
