Step‑by‑Step Instructions for Crockpot Beef Fajitas

Step 1: Prepare the Beef
Start by trimming any excess fat from 2 pounds of flank steak or sirloin and then slice the meat against the grain into thin strips. Pat the beef dry with paper towels to ensure a nice sear later. This preparation helps lock in the juicy flavors of your Crockpot Beef Fajitas.

Step 2: Chop the Vegetables
Next, slice 3 large bell peppers in various colors like red, yellow, and orange for added sweetness and visual appeal. Cut 1 large yellow onion into thin slices and mince 4-5 cloves of garlic. The combination of these fresh ingredients will create a flavorful base for your fajitas.

Step 3: Mix the Seasoning
In a small bowl, combine the spices for your seasoning blend. Add 2 tablespoons of chili powder, 1 tablespoon each of ground cumin and smoked paprika, and 1 teaspoon each of onion powder, garlic powder, dried oregano, sea salt, and freshly ground black pepper. This fragrant mixture will elevate your Crockpot Beef Fajitas with a robust flavor.

Step 4: Layer in the Slow Cooker
At the bottom of a 6-quart slow cooker, layer the sliced onions and minced garlic. Follow with the beef strips, arranging them evenly, and then top with the colorful bell pepper slices. This layering helps the flavors meld beautifully as they cook together.

Step 5: Add Seasoning and Broth
Evenly sprinkle the prepared seasoning blend over the layered ingredients in the slow cooker. Pour ½ cup of chicken or vegetable broth over the top, ensuring the beef and veggies are well coated. The broth will keep everything moist and tender, enhancing your Crockpot Beef Fajitas.

Step 6: Slow Cook the Fajitas
Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours. The beef should become tender and easily shred with a fork, while the vegetables remain vibrant and crisp-tender. Avoid opening the lid frequently to maintain consistent cooking temperatures.

Step 7: Squeeze in Lime Juice
Once the cooking time has elapsed, gently squeeze the juice of 1 lime over the cooked beef and vegetables, stirring everything together. This fresh burst of citrus will brighten the flavors of your Crockpot Beef Fajitas and give them a zesty finish.

Step 8: Warm the Tortillas
While the fajita mixture rests, warm 12-16 small tortillas in a skillet or microwave. This step ensures that the tortillas are pliable and ready to hold your flavorful fillings. Preparing them while the fajitas cool slightly creates an efficient assembly line.

Step 9: Serve and Enjoy!
To serve your delicious Crockpot Beef Fajitas, allow guests to build their own using warm tortillas filled with the beef and veggie mixture. Encourage them to add their favorite toppings like sour cream, shredded cheese, salsa, guacamole, or fresh cilantro, creating a fully customizable dining experience!
