So you’re craving something tasty but too lazy to spend forever in the kitchen, huh? Same. That’s why crockpot steak fajitas exist. Imagine all the smoky, sizzling fajita flavor you love—without having to actually stand over a hot skillet while onions sting your eyes. With this recipe, you throw a bunch of stuff in the crockpot, walk away, and come back to juicy, tender steak and perfectly cooked peppers. Dinner practically makes itself, and you still get all the credit.
Seriously, this is weeknight cooking at its finest.
Why This Recipe is Awesome
First of all, it’s idiot-proof. If you can slice some peppers and remember to plug in your crockpot, you’re good to go.
Second, it’s budget-friendly fajita night. No need for expensive cuts or fancy tools—just simple ingredients that slow-cook into greatness.
Third, it’s flexible. Want tacos? Done. Burrito bowls? Easy. Salad topping? Go for it. You’ll be recycling this one recipe into multiple meals and patting yourself on the back every time.
And let’s not forget: the house smells amazing while it cooks. Your neighbors will be jealous.
Ingredients You’ll Need
- 2 pounds flank steak or skirt steak (affordable and perfect for slow cooking)
- 3 bell peppers, sliced (use a mix of colors—because we eat with our eyes too)
- 1 large onion, sliced (yellow or white works best)
- 1 can (14 oz) diced tomatoes with green chilies (aka Rotel, the secret flavor boost)
- 3 cloves garlic, minced (because life without garlic is sad)
- 2 teaspoons chili powder
- 1 teaspoon cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon oregano
- 1/2 teaspoon salt (adjust later)
- 1/2 teaspoon black pepper
- Juice of 1 lime (added at the end for zing)
- Tortillas and toppings for serving: cheese, sour cream, guacamole, cilantro, hot sauce
Step-by-Step Instructions
- Spray or grease your crockpot lightly for easier cleanup.
- Add sliced peppers, onions, and diced tomatoes to the bottom. Spread them out evenly.
- Lay steak on top of the veggies. Sprinkle garlic and spices evenly over the meat.
- Cover and cook on low for 6–7 hours or high for 3–4 hours, until steak is tender enough to shred or slice easily.
- Remove steak and slice thinly (or shred if you prefer). Return it to the crockpot and stir everything together.
- Squeeze in lime juice for brightness. Taste and adjust seasoning.
- Serve hot in tortillas with your favorite toppings. Don’t forget to warm the tortillas unless you enjoy sadness.
Common Mistakes to Avoid
- Overcooking the steak. Yes, slow cookers are forgiving, but too much time can make the meat mushy instead of tender.
- Skipping the lime juice. That citrus kick at the end makes a huge difference. Don’t ignore it.
- Crowding the pot. Too many veggies or thick steak pieces can cook unevenly. Slice things consistently.
- Adding toppings too soon. Cheese and sour cream belong on top when serving, not swimming in the crockpot for hours.
- Thinking tortillas are optional. They’re not. Don’t ruin good fajitas with sad, cold store-bought wraps. Warm them up.
Alternatives & Substitutions
- No flank steak? Use skirt steak, sirloin, or even chuck roast.
- Want it spicier? Add jalapeños, cayenne, or chipotle powder.
- No canned tomatoes? Use salsa for an extra flavor punch.
- Low-carb? Skip tortillas and serve over cauliflower rice or lettuce wraps.
- Vegetarian version? Sub mushrooms, zucchini, or jackfruit for a fajita-style plant-based option.
- Want creaminess? Top with avocado slices or drizzle on some sour cream.
