Before you start

Before you begin cooking, gather all your ingredients and equipment to ensure a smooth process. Measure out your ground beef and canned crushed tomatoes, and have them ready at your workstation. Set up your slow cooker and plug it in. If you are browning the beef on the stove, place your skillet on the burner and have a wooden spoon ready for breaking up the meat.

Ingredients at a glance (2)
  • 1 lb lean ground beef
  • 56 oz crushed tomatoes (two 28-ounce cans)

Instructions

Browning the Beef

  1. Brown the Beef
    Heat a skillet over medium-high heat. Add the lean ground beef, breaking it up with a wooden spoon. Cook the meat until it is completely browned and no pink remains, which takes about 5 to 7 minutes. Drain any excess fat from the skillet before moving to the next step.
    Look for The beef is fully browned with no pink areas.
    Tip Breaking the beef into small crumbles ensures a uniform texture in the final sauce.

At the end of this phase, the ground beef should be completely cooked through with no visible pink areas remaining. The meat will have broken down into small, uniform crumbles, and you should hear a gentle sizzling sound in the skillet.

The kitchen will fill with the rich, savory aroma of seared beef. Ensure you drain any excess liquid or fat from the skillet before moving the beef to the slow cooker.

Combining the Ingredients

  1. Transfer to Slow Cooker
    Transfer the browned ground beef into the insert of your slow cooker. Pour the crushed tomatoes directly over the beef. Stir the mixture thoroughly with a wooden spoon to combine the ingredients evenly.
    Look for The beef and tomatoes are well mixed.
    Tip Scrape the bottom of the skillet to get any browned bits into the slow cooker for extra flavor.

After mixing the browned beef and crushed tomatoes in the slow cooker, the mixture should look uniform and well combined. The vibrant red tomatoes will coat the beef completely, and there should be no dry pockets of meat. The mixture will look relatively wet at this stage, which is normal before the slow-cooking process begins to reduce and thicken the sauce.

Slow Simmering

  1. Slow Cook the Sauce
    Cover the slow cooker with its lid. Set the temperature to low and cook for 4 hours. The sauce should bubble gently, allowing the flavors to meld and the liquid to reduce into a thick, glossy consistency.
    Look for The sauce is thick, deep red, and gently bubbling.
    Tip Keep the lid on during cooking to maintain consistent heat and moisture levels.
  2. Final Temperature Check
    Before serving, stir the sauce one last time. Insert an instant-read thermometer into the meat mixture to ensure the ground beef has reached a safe internal temperature of 160°F (71°C).
    Look for The thermometer registers at least 160°F (71°C).
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip If the sauce is too thin, let it simmer uncovered for the last 15 minutes.

By the end of the slow-cooking phase, the sauce will have transformed into a deep, rich red color with a thick, glistening consistency.

You will see gentle, lazy bubbles breaking the surface of the sauce, and the aroma of sweet tomatoes and savory beef will be highly pronounced. The tomato chunks will be tender and fully integrated, and the sauce will cling beautifully to a spoon when scooped.

Common mistakes

One common mistake is skipping the browning step and putting raw ground beef directly into the slow cooker. This results in a greasy, gray meat mixture with a boiled texture and deprives the sauce of the deep, caramelized flavors developed during searing.

Another error is leaving too much rendered fat in the pan; failing to drain the beef after browning can lead to an oily layer separating on top of your finished sauce.

How to tell it’s done

The sauce is done when it has thickened to your liking, displaying a glossy, deep red appearance with tender tomato chunks. To guarantee food safety, always insert an instant-read thermometer into the meat mixture to verify that the ground beef has reached a safe internal temperature of 160°F (71°C).

If the sauce is still too watery, simmer it uncovered for an additional fifteen to twenty minutes to allow excess moisture to evaporate.
