Before you start

Before you begin, ensure you have all your ingredients measured and ready. Slice the onions and bell peppers into uniform strips to ensure they cook evenly.

Pat the beef steaks completely dry with paper towels before placing them in the slow cooker. Have your slow cooker placed on a stable surface away from the edge of the counter, and ensure you have a clean workspace for the preparation phase.

Ingredients at a glance (4)
  • 2 lb beef round steak, trimmed
  • 1 large yellow onion, sliced
  • 1 large green bell pepper, sliced
  • 28 oz canned crushed tomatoes

Instructions

Vegetable preparation

  1. Prepare the vegetables
    Slice the yellow onion and green bell pepper into uniform strips. Place the sliced vegetables into the bottom of the slow cooker to create a bed for the beef.
    Look for The vegetables should be sliced into consistent strips for even cooking.
    Tip Uniform slicing ensures that the onions and peppers soften at the same rate.

The onions and peppers should be sliced into uniform strips. When placed in the slow cooker, they should form an even layer at the bottom. The kitchen should be ready for the assembly phase, with the beef trimmed and the slow cooker positioned on a stable surface, ensuring all ingredients are prepared and ready for the slow cooking process.

Assembly of ingredients

  1. Assemble the dish
    Place the beef round steak on top of the vegetables in the slow cooker. Pour the crushed tomatoes over the beef, ensuring the meat is well-coated by the sauce.
    Look for The beef should be completely covered by the tomato sauce mixture.
    Tip Ensure the beef is lying flat to allow for even heat distribution during the cooking process.

The beef should be placed securely on top of the vegetable bed. The crushed tomatoes should be poured evenly over the meat, ensuring full coverage. The slow cooker should be set to the low setting.

Check that the lid is properly seated to trap the heat and moisture, which are essential for the long, slow braising process that will tenderize the beef.

Slow cooking cycle

  1. Slow cook
    Cover the slow cooker and cook on low for 8 hours until the meat reaches an internal temperature of 145°F (63°C). Let the meat rest for at least 5 minutes before serving.
    Look for The beef is done when it is fork-tender and pulls apart easily.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Avoid opening the lid during the cooking process to maintain a consistent temperature.

The beef will be extremely tender and the sauce should have thickened significantly during the slow cook. The vegetables should be very soft, almost melting into the tomato sauce. The aroma should be deep, savory, and rich. Before serving, ensure the steak is tender enough to cut with a fork and that the sauce consistency is to your liking.

Common mistakes

A common mistake is failing to trim excess fat from the beef, which can lead to a greasy sauce. Another error is adding too much liquid; the vegetables and beef will release their own moisture during the cooking process, so the sauce should be thick and concentrated.

Ensure you do not lift the lid frequently, as this releases heat and moisture, which can significantly increase the cooking time required to reach the desired tenderness.

How to tell it’s done

The steak is perfectly done when it is fork-tender, meaning it can be easily shredded or pulled apart with a fork. Use a meat thermometer to ensure the beef reaches an internal temperature of at least 145°F (63°C).

Because round steak is a lean cut, reaching this temperature is vital for safety, and the extended cooking time ensures it becomes soft rather than tough, provided you let it rest for the full duration before serving.

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