Essential Ingredients for Crockpot Carne Asada
Crafting the perfect slow cooker carne asada begins with a masterful blend of spices and a touch of zesty citrus. The journey starts by combining aromatic spices to create a rich rub that will infuse the flank steak with incredible flavor. This seasoned steak then nestles into the slow cooker, bathed in freshly squeezed orange and lime juices, complemented by a hint of vinegar, and gently braised on low heat until it reaches peak tenderness.
And, of course, no carne asada experience is complete without the perfect accompaniments! We highly recommend serving this dish with warm tortillas, vibrant pico de gallo, fresh cilantro, and a generous drizzle of our amazing 10-minute flourless queso for an unforgettable meal!

For the Flavorful Spice Rub and Braising Liquid:
- Flank Steak: The star of our dish. This lean, flavorful cut benefits immensely from slow cooking. (See below for details on alternative cuts of meat.)
- Ground Cumin: Adds a warm, earthy, and distinctly Mexican flavor profile.
- Garlic Powder: Provides a foundational aromatic depth without the need for chopping fresh garlic.
- Smoked Paprika: Essential for that characteristic smoky aroma and deep reddish hue. While any paprika works, smoked paprika truly elevates the flavor.
- Chili Powder: A blend of spices that brings mild heat and complex savory notes.
- Onion Powder: Enhances the savory base notes, complementing the garlic.
- Cayenne Pepper: For a subtle kick; adjust to your preferred level of spice.
- Olive Oil: Helps bind the spice rub and tenderize the meat.
- Fresh Orange: Provides a natural sweetness and tenderizing acidity.
- Fresh Lime: Adds essential bright, tangy citrus notes that are characteristic of authentic carne asada.
- White Wine Vinegar: (or apple cider vinegar) Contributes additional acidity, helping to tenderize the meat and balance the rich flavors.
- Fresh Cilantro: Used both in the cooking liquid for fresh herb notes and as a garnish.
To serve as tacos, you’ll need a stack of warm tortillas and your favorite optional toppings. Consider additions like crisp lettuce, shredded cheese, various salsas (verde or roja), cooling sour cream or Mexican crema, and creamy sliced avocado or guacamole. The possibilities are endless!
Step-by-Step Guide: How to Make Slow Cooker Carne Asada
Creating this incredibly delicious slow cooker carne asada is simpler than you might imagine. Follow these easy steps to achieve tender, flavor-packed steak that’s perfect for tacos, burritos, or any Mexican-inspired meal.

- Prepare the Spice Rub: In a small bowl, combine all the dry spices (cumin, smoked paprika, chili powder, garlic powder, onion powder, salt, pepper, and cayenne pepper). Add the olive oil and mix thoroughly until a thick, fragrant paste forms. This paste ensures the spices adhere beautifully to the steak.
- Season the Steak: Generously rub the spice mixture all over both sides of the flank steak, ensuring every inch is coated. This step is crucial for building a deep flavor foundation.
- Assemble in the Slow Cooker: Carefully transfer the seasoned flank steak to your slow cooker. Pour the freshly squeezed juice from the orange and lime over the meat, along with the white wine vinegar. Finally, sprinkle the freshly chopped cilantro on top. These liquids will create a wonderfully aromatic braising liquid.
- Slow Cook to Perfection: Cover the slow cooker and cook on the LOW setting for 5-6 hours. The extended cooking time on low heat is key to breaking down the fibers of the flank steak, resulting in incredibly tender meat.
- Rest and Slice: Once cooked, carefully remove the steak from the slow cooker and place it on a cutting board. Allow it to rest for at least 5 minutes before slicing. Resting helps the juices redistribute throughout the meat, keeping it moist and tender. Then, slice the steak thinly against the grain (perpendicular to the muscle fibers) to maximize tenderness. Serve the sliced carne asada with the reserved flavorful juices from the slow cooker, if desired, and your favorite taco fixings.

Flank Steak vs. Skirt Steak: Choosing Your Cut
While this recipe highlights the deliciousness of flank steak, you can certainly adapt it to create mouth-watering crock pot skirt steak tacos. The preparation method and cooking time will generally remain the same, making it an easy substitution.
However, it’s important to note the textural difference. Skirt steak is typically a thinner cut of meat than flank steak. When slow-cooked, skirt steak tends to become a little stringier and incredibly tender, often resembling shredded taco meat. This can be a desirable texture for some, offering a different but equally delicious experience.
After experimenting with both flank and skirt steak, I’ve found that **flank steak tends to hold up better to the extended slow cooking process**, maintaining a more defined sliceable texture while still achieving exceptional tenderness. If you prefer a meat that can be sliced into distinct pieces rather than shredded, flank steak is generally the superior choice for this recipe. Another excellent option for slow cooking, providing a wonderfully rich and tender result, would be a **brisket** cut, though it may require a longer cooking time.
Delicious Serving Ideas Beyond Tacos
The beauty of this slow cooker carne asada lies not only in its ease and flavor but also in its incredible versatility. Since it produces such a wonderfully tender and juicy filling, it naturally excels as the star of steak tacos. But why stop there?
If you’re looking for creative ways to enjoy this flavorful meat beyond traditional flank steak tacos, here are some yummy serving suggestions:
- Taco Salad: Layer fresh greens with the tender carne asada, black beans, corn, diced tomatoes, avocado, and a zesty dressing for a hearty and satisfying salad.
- Burrito Bowls: Create customized bowls with a base of cilantro lime rice, topped with carne asada, pinto or black beans, salsa, guacamole, cheese, and a dollop of sour cream.
- Quesadillas: Shred the carne asada slightly and layer it between tortillas with plenty of cheese, then grill until golden and melty.
- Steak and Eggs (Mexican Style): Serve the carne asada alongside scrambled or fried eggs, warm tortillas, and a side of salsa for a flavorful breakfast or brunch.
- Nachos Supreme: Pile tortilla chips high with carne asada, queso, jalapeños, olives, and all your favorite nacho toppings.
- Stuffed Bell Peppers: Mix the carne asada with rice and some additional veggies, then stuff into bell peppers and bake until tender.
- Sandwiches or Wraps: Use the sliced carne asada as a flavorful filling for a unique steak sandwich or a hearty wrap.
Expert Tips for Cutting Flank Steak Like a Pro
Achieving perfectly tender carne asada isn’t just about the cooking process; how you slice the meat plays an equally crucial role. Flank steak, by nature, has long, visible muscle fibers, and cutting it correctly is essential to maximize tenderness and enjoyability.
Here’s how to ensure your slow cooker flank steak is incredibly tender with every bite:
- Rest the Meat: After the steak has finished cooking in the crock pot, remove it and place it on a clean cutting board. It’s vital to let it rest for at least 5-10 minutes. This resting period allows the juices within the meat to redistribute throughout the fibers. If you slice it too soon, those delicious juices will run out, leaving you with drier meat.
- Identify the Grain: Before you make the first cut, take a moment to observe the steak. You will notice distinct lines running through the fibers of the meat. These lines are known as “the grain.”
- Slice Against the Grain: The golden rule for cutting flank steak (and other similar cuts like skirt steak) is to slice against the grain. This means you should cut perpendicular to these visible muscle fibers, not in the same direction. Cutting against the grain shortens the muscle fibers, making the meat much easier to chew and giving it a more tender texture. Aim for thin slices, about ¼-inch thick, for the best results.

Notes
Other cuts of meat
You may substitute skirt steak with preparation and cooking time remaining same.
However, skirt steak is a thinner cut of meat than flank steak, so the texture will be a little stringier and tender, more like shredded taco meat.
I’ve tested the recipe with both flank and skirt steak, and the flank steak held up better to the slow cooking. Another option, though, would be a brisket.
How to serve
If you are looking for something besides flank steak tacos, you may also serve carne asada over a taco salad, with rice and beans, burrito bowl, or as a Mexican-inspired steak and eggs.
How to slice flank steak
After the steak has finished cooking, remove it from the crock pot and let it rest for 5 minutes on a cutting board.
To cut flank steak, slice the meat against the grain. This means you will see lines running through the fibers of the meat. Do not slice in the same direction as these fibers, but cut perpendicular to them.
