This 4-ingredient slow cooker beef is the kind of easy dinner that saves busy weeknights and still feels hearty enough for a family meal. Using frozen beef fajita strips keeps prep to a minimum, and the slow cooker does all the work while the beef turns tender and flavorful. It is a simple dump-and-go recipe that works especially well for tacos, rice bowls, sandwiches, or big plates with comforting sides.
Serve this beef tucked into warm tortillas with shredded cheese and sour cream, spooned over rice or mashed potatoes, or piled onto sandwich buns for a simple supper. For family-style sides, I like corn, black beans, a green salad, or roasted peppers and onions, and you can set out favorite toppings so everyone can build their own plate.
4-Ingredient Slow Cooker Beef
Servings: 6
Ingredients
2 pounds frozen beef fajita strips
Directions
1. Add the frozen beef fajita strips to the bottom of the slow cooker. Sprinkle the taco seasoning evenly over the top, then add the sliced onion and spoon the salsa over everything.
2. Cover and cook on low for 6 to 8 hours or on high for 4 to 5 hours, until the beef is tender and heated through.
3. Stir well, breaking up the beef if needed so it soaks up the juices and mixes evenly with the onions and salsa.
4. Serve hot in tortillas, over rice, or however your family likes it best.
Variations & Tips
For picky eaters: If your family prefers simpler flavors, use a mild salsa and serve the onions on the side instead of cooking them in the pot. You can also tuck the beef into quesadillas with cheese for an easy kid-friendly meal.
Make it heartier: Spoon the beef over baked potatoes, mashed potatoes, or rice to stretch the meal a little further when you are feeding a crowd. The savory juices are wonderful over starches and help make the whole plate feel extra cozy.
Add more vegetables: Bell peppers are a great addition if you want more fajita flavor. Slice them and add them during the last 1 to 2 hours of cooking so they stay a little tender-crisp instead of getting too soft.
Storage tip: Leftover beef keeps well in the refrigerator for up to 4 days in a covered container. Reheat gently with a spoonful of extra salsa or broth if needed to keep it moist.
