This 5-ingredient slow cooker beef is the kind of weeknight recipe I lean on when work runs late, the kids’ activities run long, and I still want the house to smell like I’ve been cooking all day. Thinly sliced raw beef strips go straight into the slow cooker, then get drenched in a glossy, sweet-savory amber sauce that tastes like something from your favorite takeout spot—without the extra effort. It’s not tied to any specific traditional cuisine, but it borrows a little inspiration from simple Midwest pot roast comfort food and a touch of Asian-style sweetness. The best part? You dump everything in before work, and by dinner your friends and family will be asking, “Okay, you HAVE to send me this recipe.”
Serve these tender, saucy beef strips over a bed of fluffy white rice, brown rice, or buttery egg noodles so they can soak up every bit of that bright amber sauce. Add a simple side like steamed broccoli, green beans, or a bag of frozen stir-fry veggies tossed with a little salt and olive oil. If you’re feeding a crowd, put out a big salad, some crusty bread, and maybe a bowl of pickled veggies or coleslaw to cut through the richness of the beef. Leftovers are fantastic tucked into warm tortillas, spooned over baked potatoes, or piled on soft rolls for easy sandwiches.
5-Ingredient Slow Cooker Beef StripsServings: 4
Ingredients
1 1/2 pounds thinly sliced raw beef strips (such as sirloin or flank steak, cut against the grain)
3/4 cup low-sodium beef broth
1/2 cup soy sauce (regular or low-sodium)
1/3 cup packed brown sugar
2 tablespoons cornstarch
Directions
Lay the thinly sliced raw beef strips in an even layer on the bottom of a 4- to 6-quart slow cooker. If some pieces overlap, that’s fine, but try to spread them out so the sauce can coat everything well.
In a medium bowl or large measuring cup, whisk together the beef broth, soy sauce, and brown sugar until the sugar is mostly dissolved and the liquid looks like a smooth, bright amber sauce.
Pour the amber sauce evenly over the beef strips in the slow cooker, making sure all the meat is moistened. The beef should be mostly submerged, but it’s okay if a few pieces peek out.
Cover the slow cooker with the lid and cook on LOW for 4–5 hours or on HIGH for 2–3 hours, until the beef strips are very tender and easily pull apart with a fork.
About 20 minutes before serving, scoop out about 1/2 cup of the hot cooking liquid from the slow cooker into a small bowl. Whisk the cornstarch into this hot liquid until completely smooth with no lumps.
Stir the cornstarch mixture back into the slow cooker, gently mixing it into the beef and sauce. Cover again and cook on HIGH for another 15–20 minutes, or until the sauce has thickened into a glossy, clingy coating around the beef.
Taste and adjust seasoning if needed (you can add a splash more soy sauce for saltiness or a pinch more brown sugar for sweetness). Serve the saucy beef strips hot over rice, noodles, or your favorite side.
Variations & Tips
To make this recipe even more weeknight-friendly, you can prep the beef strips and sauce the night before: place the sliced beef in the slow cooker insert, whisk the broth, soy sauce, and brown sugar together, pour it over the beef, cover, and refrigerate overnight. In the morning, set the insert into the slow cooker base and start cooking. For extra flavor without adding more ingredients, use a richer beef broth or a splash of Worcestershire sauce in place of part of the soy sauce. If you like a little heat, stir in a pinch of red pepper flakes or a drizzle of hot sauce along with the cornstarch slurry. To bulk up the meal, add sliced onions or bell peppers on top of the beef before pouring on the sauce (this technically ups the ingredient count, but it’s an easy way to stretch the dish). For a lighter version, use leaner cuts like top round and trim visible fat, then skim any fat from the top of the sauce before thickening. Leftovers reheat well in the microwave with a splash of water or broth; they also freeze nicely for up to 2–3 months, making this a great meal-prep option for busy weeks.
