Jump to RecipeIngredients Needed
- 1 whole beef flank steak: tender when sliced thin across the grain, trust me.
- ½ cup olive oil: base of your marinade.
- 3 tbsp Worcestershire sauce: salty, punchy, classic.
- ⅓ cup fresh lime juice: bottled stuff’s just sad, don’t do it.
- 3 cloves garlic, minced: not too much or it overpowers.
- 1 tbsp cumin: gives it that “real” tex-mex vibe.
- 1 tbsp chili powder
- ½ tsp red pepper flakes: scale back if your mouth is sensitive, lol.
- 1 tsp salt
- ½ tsp black pepper
- 1 tbsp sugar: trust the process, it balances everything.
- 2 medium onions, sliced: they’ll caramelize and it’s magic.
- 1 red, 1 orange, 1 green, 1 yellow bell pepper: yes, it’s a rainbow, no, you don’t need all 4.
- Oil for frying: doesn’t need much.
- Flour tortillas, warmed: don’t skip warming them. They matter.
- Toppings: cheese (cheddar or queso fresco), salsa, sour cream, cilantro — freestyle it.
How To Make Slow Cooker Beef Fajitas
Marinate the Steak & Veggies:
In two separate dishes, mix up the marinade. One bowl for steak. One for the peppers and onions. Cover and let sit in the fridge — 2 hours minimum, overnight if you’re responsible.
Cook the Veggies:
Drizzle oil into a hot pan. Toss in the peppers/onions. Let ’em char a bit. Don’t stir too often or they won’t get that golden edge. This is the part where your kitchen smells amazing.
Sear the Steak:
Same pan. High heat. 2 minutes per side. You want brown crust outside, pink in the middle. Let it rest for 5 mins or it’ll leak juice everywhere when you slice.
Slice + Serve:
Slice steak thin, across the grain. Toss on a tortilla, top with veggies, sour cream, cheese, whatever you’ve got. Fold. Eat. Repeat.

Recipe Tips
- Marinate overnight if you can: lazy planning = flavour payoff.
- Cut across the grain: or the meat’s just chewy sadness.
- Char those veggies: it’s not burnt, it’s character.
- Can’t handle spice? Leave out the red pepper flakes. Easy.
- Tortilla matters: warm them or the whole thing falls flat.
How to Store & Reheat
- Room Temp: Don’t. It’s meat. Put it away.
- Fridge: Airtight container, 3 days max.
- Freezer: Freeze meat and veggies separately if you’re fancy. Up to 3 months.
- Reheat: Skillet = better. Microwave = acceptable if you’re desperate.

FAQs
Can I make this with chicken?
Yeah, boneless thighs work great. Same marinade, just adjust cook time.
Do I have to use all four peppers?
Nope. One or two is fine. More just looks pretty and adds variety.
Is this really a slow cooker meal?
Kinda. But honestly it’s more of a marinate + skillet job. “Slow cooker” is just marketing here.
How spicy is it?
Mild-medium. You can skip the flakes if you’re spice-sensitive or feeding kids.
What tortillas work best?
Flour all the way. Corn’s cool but tends to break unless warmed perfectly.
