Step-by-Step Guide: How to Make Chili-Lime Flank Steak
Step 1: Prepare the Marinade
In a bowl, whisk together:
- Lime juice
- Olive oil
- Chili powder
- Cumin
- Garlic powder
- Salt
- Black pepper
Mix until well combined.
Step 2: Marinate the Steak
- Place flank steak in a shallow dish or resealable bag.
- Pour marinade over the steak.
- Coat evenly.
- Refrigerate for at least 30 minutes (up to 4 hours for deeper flavor).
Avoid marinating longer than 4 hours, as excessive acidity can affect texture.
Step 3: Bring to Room Temperature

Step 4: Cook the Flank Steak
Option 1: Grill Method

- Sear steak 4–5 minutes per side.
Avoid moving the steak too much to achieve a good crust.
Step 5: Rest the Steak
Transfer steak to a cutting board.
Let it rest for 10 minutes before slicing.
This prevents juices from escaping.
Step 6: Make the Avocado Salsa
In a bowl, gently combine:
- Diced avocado
- Red onion
- Cilantro
- Jalapeño
- Lime juice
- Salt
Mix carefully to keep avocado pieces intact.
