Step‑by‑Step Instructions for Juicy Chili-Lime Flank Steak with Fresh Avocado Salsa
Step 1: Marinate the Steak
In a mixing bowl, whisk together lime juice, chili powder, garlic powder, onion powder, salt, and pepper to create a vibrant marinade. Place your flank steak in a large resealable bag, pour the marinade over it, and seal tightly, ensuring the steak is well-coated. Allow it to marinate in the refrigerator for at least 2 hours, or up to 8 hours for deeper flavor.
Step 2: Prepare the Salsa
While the steak marinates, prepare the fresh avocado salsa. Dice the avocado into bite-sized pieces and place them in a mixing bowl. Finely chop the jalapeño and cilantro, adding them to the bowl. Gently mix the ingredients together, adjusting any spice levels to your preference. Cover and set aside for flavors to meld while the steak is grilling.
Step 3: Grill the Steak
Preheat your grill to medium-high heat, aiming for around 400°F. Remove the marinated flank steak from the bag and place it on the grill. Cook for approximately 6-8 minutes per side. Use an instant-read thermometer to check for doneness—remove the steak when it reaches 135°F for medium-rare. Enjoy the mouthwatering aroma as it chars beautifully.
Step 4: Rest the Steak
Once grilled to perfection, remove the steak from the grill and let it rest on a cutting board for about 5 minutes. This resting period is essential, as it allows the juices to redistribute throughout the meat, ensuring every bite of your chili-lime flank steak is juicy and tender.
Step 5: Slice and Serve
Carefully slice the rested flank steak against the grain into thin strips. Serving it warm, accompany the slices with the fresh avocado salsa. Enjoy it on warm tortillas for a delightful taco experience, or over cilantro lime rice for a fulfilling meal that is sure to please everyone at the table.

Juicy Chili-Lime Flank Steak with Avocado Salsa Recipe FAQs
How do I select ripe avocados for the salsa?
Absolutely! Look for avocados that are slightly soft to the touch but not mushy. A ripe avocado should yield to gentle pressure; if it has dark spots or feels overly squishy, it may be overripe. If you’re not using them immediately, prickly skin or a firm one will ripen in a paper bag at room temperature within 3 to 5 days.
What is the best way to store leftover chili-lime flank steak?
To store leftover chili-lime flank steak, wrap it tightly in foil or place it in an airtight container. It will stay fresh in the fridge for up to 2 days. Just remember to let it cool completely before wrapping to avoid condensation and maintain texture.
Can I freeze the steak for later use?
Absolutely! To freeze the chili-lime flank steak, I recommend slicing it first for easier portioning. Place the sliced steak in a freezer-safe bag, removing as much air as possible. It will keep well in the freezer for up to 3 months. When you’re ready to enjoy, thaw it in the refrigerator overnight and reheat at 300°F until warmed through for the best results.
How can I prevent the avocado from browning?
Very! To prevent browning, wait to add the avocado to your salsa until just before serving. If you’re prepping in advance, you can sprinkle the diced avocado with lime juice, which will help slow down oxidation. Store any leftover salsa in an airtight container with a layer of plastic wrap pressed against the surface to limit air exposure, helping it last up to 1 hour before it starts to brown.
Can this recipe be modified for dietary restrictions?
Certainly! This chili-lime flank steak is gluten-free as is, but for those with meat allergies, you can marinate and grill portobello mushrooms instead for a delicious vegetarian alternative. The marinade works wonderfully with various vegetables, so don’t hesitate to get creative based on your dietary needs or preferences!
