Why Make Steak Fajitas in a Slow Cooker?

• Customizable: Easily adjust the spice level, use your favorite toppings, and scale the recipe up or down as needed.

Ingredients

Below is a classic lineup for slow cooker steak fajitas. Feel free to add your own twists for extra flavor or convenience.

• 2 pounds flank steak (or skirt steak), cut into 2-3-inch strips
• 1 large yellow onion, thinly sliced
• 1 red bell pepper, cut into strips
• 1 green bell pepper, cut into strips
• 2 cups tomato salsa (choose your favorite variety or make your own)
• 1/4 cup beef broth
• 2 tablespoons fajita seasoning mix
• Optional: 2 tablespoons freshly squeezed lime juice
• Optional: 2 tablespoons chopped jalapeños (for heat)
• Optional: 2 cloves garlic, minced

Fajita Seasoning Mix (Homemade Option)

• 1 teaspoon chili powder
• 1 teaspoon smoked paprika
• 1 teaspoon ground cumin
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon dried oregano
• 1/4 teaspoon cayenne pepper (optional, for heat)
• Salt and black pepper to taste

Instructions

1. Prepare the Steak: Trim any excess fat off the flank steak and cut it into 2- to 3-inch wide portions. This makes shredding or slicing easier after cooking.
2. Layer in Slow Cooker: Arrange the sliced onions and bell peppers on the bottom of your slow cooker. Place the steak strips on top.
3. Add the Flavor: Pour salsa and beef broth over the steak. Sprinkle the fajita seasoning evenly over all the ingredients. If using, add lime juice, jalapeños, and minced garlic now.
4. Stir to Combine: Use a spatula or spoon to gently mix everything together. This helps distribute the seasoning and ensures the beef is coated.
5. Cook: Cover and cook on high for 4-5 hours or low for 6-8 hours, until the beef is fork-tender and the vegetables have softened. If you like crisp-tender peppers, add them in the last 30-60 minutes of cooking instead of at the start.
6. Shred or Slice the Beef: Transfer the cooked steak to a cutting board. Use two forks to shred it into bite-sized pieces, or slice thinly against the grain for tender strips.
7. Return Beef to Sauce: Place the shredded or sliced beef back in the slow cooker and stir to coat in the flavorful juices.
8. Serve: Spoon the steak and veggies onto warm flour or corn tortillas. Add your favorite toppings and enjoy!

Tips for the Best Slow Cooker Steak Fajitas

• Choose the Right Cut: Flank steak, skirt steak, or even sirloin work best for fajitas. They become tender with slow cooking and shred or slice easily.
• Don’t Overcook: While slow cookers are forgiving, overcooking can make the peppers mushy. Add bell peppers later in the process for more texture.
• Boost the Flavor: A few splashes of lime juice at the end of cooking add brightness. Fresh cilantro or extra chili flakes can enhance the flavor profile.
• Keep It Moist: If your slow cooker runs hot or if you’re using a lean cut, check the liquid level halfway through. Add an extra splash of broth if needed to prevent sticking or drying out.

Recommended Toppings and Sides

Customize your fajitas with a variety of toppings and sides to suit your taste and occasion:

• Shredded cheese (cheddar, Monterey Jack, or queso fresco)
• Sour cream or Greek yogurt
• Fresh salsa or pico de gallo
• Guacamole or sliced avocado
• Chopped fresh cilantro
• Lime wedges
• Pickled red onions
• Jalapeño slices

Serve with classic sides like Mexican rice, refried beans, or a crisp green salad for a complete meal.
