Before you start

Before beginning, ensure all ingredients are prepped and ready within reach, as the cooking process moves very quickly. Slice the beef into thin, uniform strips against the grain to ensure even cooking and tenderness.

Wash, seed, and slice the bell peppers into consistent strips. Having everything measured and placed near the stove prevents overcooking while searching for ingredients. Keep a plate ready to hold the beef after it is seared to allow it to rest properly.

Ingredients at a glance (2)
  • 1 lb flank steak, thinly sliced
  • 2 cups mixed red and green bell peppers, sliced

Instructions

Searing the Beef

  1. Sear the Beef
    Heat a large skillet over high heat until very hot. Add the sliced beef in a single layer and sear until deeply browned on all sides, ensuring the meat is cooked through to 145°F (63°C). Remove the beef from the skillet and let it rest on a plate for at least 3 minutes to maintain tenderness.
    Look for The beef should be deeply browned and sizzling loudly in the pan.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Avoid overcrowding the pan, as this causes the beef to steam rather than sear.

The beef should be browned with a visible crust on the exterior. The pan will be very hot, and the meat should sizzle continuously. Once the beef reaches 145°F (63°C), transfer it to a plate.

The meat will smell savory and slightly caramelized, signaling that the base flavor for the dish is established and ready for the next stage.

Sautéing the Peppers

  1. Sauté the Peppers
    Add the sliced bell peppers to the same skillet over medium-high heat. Sauté for 2 to 3 minutes until they are bright and crisp-tender. Keep the heat high to maintain the vibrant color of the peppers.
    Look for The peppers should glisten and retain a firm, crisp texture when bitten.
    Tip Do not overcook the peppers, or they will lose their crunch and bright color.

The peppers should look vibrant and glossy. They will be softened but still retain their shape and a crisp texture. The skillet should be fragrant with the scent of cooked peppers. Check that they are not becoming mushy or losing their bright color; they should be ready for the final step as soon as they are tender-crisp.

Glazing the Dish

  1. Glaze and Serve
    Return the seared beef to the skillet with the peppers. Toss everything together for 1 to 2 minutes until the ingredients are coated in a glossy finish. Serve immediately while hot and steaming.
    Look for The ingredients should glisten and look coated, creating a shiny, dark appearance.
    Tip Use metal tongs to toss the ingredients efficiently without damaging the tender meat.

The final dish will appear coated in a thick, shiny, dark glaze. The aroma will be rich and savory. Ensure everything is heated through and the components have combined evenly. The meal should look glistening and smell deeply aromatic, indicating it is ready to be served immediately while the steam is still rising.

Common mistakes

A common mistake is overcrowding the skillet, which lowers the pan temperature and causes the beef to steam in its own juices rather than searing. This leads to grey, tough meat instead of browned, flavorful steak.

Another error is failing to slice the beef against the grain, which results in chewy, difficult-to-eat pieces. Finally, failing to get the pan hot enough before adding the beef prevents the meat from browning properly, as the moisture will interfere with the searing process.

How to tell it’s done

The beef is perfectly done when it reaches an internal temperature of 145°F (63°C), indicating a medium-rare to medium doneness that remains tender.

The peppers should be crisp-tender, meaning they are slightly softened but still retain a distinct snap. The appearance should be glossy and dark, with the glaze clinging to the meat and vegetables without leaving a thin, watery residue in the pan.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
