This 4-ingredient slow cooker beef carnitas recipe is the kind of simple, set-it-and-forget-it meal I lean on during long summer days when I’d rather sit on the porch than stand over a hot stove. It’s my Midwestern spin on the slow-braised Mexican-style carnitas I first tasted at a church potluck years ago, only here we use a humble beef flank steak and let the slow cooker do the work. As it bubbles away, the meat turns deeply caramelized and shreddable, the juices become glossy and rich, and the whole house fills with that savory, comforting aroma that makes everyone wander into the kitchen asking when supper will be ready.
Pile the shredded beef into warm flour or corn tortillas and top with what you like: chopped onion, cilantro, a squeeze of lime, or even a spoonful of jarred salsa from the pantry. For a heartier Midwestern-style plate, serve the carnitas over rice or buttered egg noodles with a side of sweet corn, coleslaw, or a simple green salad. Leftovers are lovely tucked into quesadillas, scattered over baked potatoes, or served in bowls with beans, rice, and a handful of shredded cheese for an easy next-day meal.
4-Ingredient Slow Cooker Beef Carnitas
Servings: 6
Ingredients
2 1/2 to 3 pounds raw beef flank steak, excess surface fat trimmed
1 cup thick salsa (mild or medium, your favorite jarred brand)
1 (4-ounce) can diced green chiles, undrained
1 packet (1 ounce) low-sodium taco seasoning mix
Directions
Lay the raw beef flank steak flat on a cutting board and pat it dry with paper towels. Trim any large, hard pieces of surface fat so the finished meat is rich but not greasy.
Place the flank steak in the bottom of a 5- to 6-quart slow cooker, folding it slightly if needed so it fits in a single, even layer. This helps it cook evenly and develop those tender, shreddable fibers.
In a medium bowl, stir together the thick salsa, the entire can of diced green chiles with their juices, and the taco seasoning mix until well combined. This simple mixture will become the glossy, savory sauce that bathes the meat as it cooks.
Pour the salsa mixture evenly over the flank steak, lifting the meat slightly with a fork so some of the mixture can slip underneath. Spoon a little of the mixture over any exposed areas so the beef is well coated.
Cover the slow cooker with the lid and cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the beef is very tender and easily shreds with a fork. During this time, avoid lifting the lid too often so the slow cooker can maintain a steady temperature and the house can fill with that wonderful all-day aroma.
Once the beef is fork-tender, use two forks to shred it directly in the slow cooker, pulling along the grain into thin strands. The meat should be saturated with a thick, glossy sauce, with rich, gelatinous bits throughout from the long, slow cooking.
Stir the shredded beef well so it soaks up as much of the sauce as possible. If the mixture seems too loose, leave the lid off and cook on HIGH for another 15 to 20 minutes, stirring occasionally, until the liquid reduces to a thick, clingy consistency that coats the meat.
For charred, caramelized edges like classic carnitas, preheat your oven broiler and line a baking sheet with foil. Spread a layer of the shredded beef and some of its sauce onto the sheet. Broil for 4 to 6 minutes, watching closely, until the tips and edges are browned and just beginning to char, with glossy juices bubbling around them. Toss lightly and broil another 2 to 3 minutes if you’d like even more crispy bits.
Return the broiled beef and its caramelized juices to the slow cooker, stirring to combine with the remaining meat and sauce. Taste and adjust seasoning if needed by adding a pinch of salt or an extra spoonful of salsa. Serve hot in tortillas or as desired, letting everyone admire the tender shreds and glistening sauce you coaxed out of just four simple ingredients.
Variations & Tips
If you prefer a bit more heat, use hot salsa or add a pinch of crushed red pepper along with the taco seasoning. For a smokier flavor, choose a salsa with chipotle or fire-roasted tomatoes, or lightly sear the flank steak in a hot skillet before placing it in the slow cooker (this adds flavor but is optional and not required for tenderness). If you want the sauce a touch sweeter to balance the savoriness, stir in 1 to 2 teaspoons of brown sugar at the end of cooking. For a leaner option, you can trim the flank steak more aggressively, but keep in mind that some fat and connective tissue are what give you that luscious, gelatinous texture after a long cook. Leftovers freeze well: cool completely, portion into freezer bags with some sauce, press out the air, and freeze up to 3 months; reheat gently with a splash of water or broth. Food safety tips: Always start with fresh, properly refrigerated beef and keep it chilled until you’re ready to cook. Do not use frozen solid meat directly in the slow cooker—thaw it fully in the refrigerator first so it passes through the temperature “danger zone” (40°F to 140°F) quickly and cooks evenly. Make sure your slow cooker is at least half full but not more than about two-thirds full for safe, even heating. The beef should reach at least 190°F internally for easy shredding; using the LOW setting for the full time helps tenderize the meat thoroughly. Refrigerate leftovers within 2 hours of cooking in shallow containers so they cool quickly, and reheat to at least 165°F before serving again.
