Getting the flavors just right for this recipe means using a few simple yet essential ingredients that each play an important role in building its delicious layers.

⅓ cup extra virgin olive oil: Adds richness and helps carry the marinade flavors deep into the meat.
2 cloves garlic (minced): Offers a warm aromatic base that complements the sweetness.
2 tablespoons lemon juice (about 1 lemon): Brightens the marinade with fresh acidity.
¼ cup coconut aminos (or low-sodium soy sauce): Provides savory depth and umami without overpowering.
⅓ cup fresh pineapple juice (canned works too): The star ingredient for its natural sweetness and tenderizing enzymes.
4 tablespoons maple syrup (divided): Balances the pineapple’s tang with a subtle caramel-like sweetness.
1 teaspoon kosher salt: Enhances and rounds out all the flavors nicely.
½ teaspoon pepper: Adds just a touch of gentle heat.
2 lb flank steak: Or skirt steak or flat iron steak as alternatives, known for flavorful lean cuts perfect for grilling.
1 medium pineapple (cut into spears, about 10-12): For grilling alongside the steak to infuse more smoky sweetness.
1 tablespoon maple syrup: Coats the pineapple spears before grilling for extra caramelization.
1 jalapeno (minced): Gives the salsa a bright, slightly spicy kick.
1 red bell pepper (cut into rings or thick strips): Adds crunch and vibrant color both on the grill and in the salsa.
½ red onion (diced): Brings a sharp, fresh bite to the pineapple salsa.
2 tablespoons lime juice (about 1 lime): Injects zesty brightness into the salsa mix.
2 tablespoons fresh chopped cilantro: Gives the salsa an herbaceous freshness that pairs beautifully with the grilled flavors.

Step 1: Marinate the Steak

Start by whisking together the marinade ingredients in a large gallon freezer bag or bowl. This pineapple marinade is magic for tenderizing the flank steak and layering it with sweet, tangy, and savory notes. Once combined, submerge your steak in this flavorful bath and pop it into the fridge to marinate for 2 to 4 hours. This step ensures every bite will be juicy and deeply infused with Caribbean-inspired brightness.

Step 2: Prep the Pineapple

When you’re ready to grill, prepare the pineapple spears by slicing them and tossing them in a bowl with 1 tablespoon of maple syrup. This little touch helps caramelize the pineapple beautifully on the grill, creating those perfect sweet, smoky char marks that complement the steak splendidly.

Step 3: Grill Steak and Veggies

Preheat your grill to a high heat, approximately 450°F, to sear the steak perfectly. Shake off any excess marinade and place the flank steak on the grill, closing the lid to trap heat. Grill each side for about 4-5 minutes, aiming for an internal temperature of 130°F to achieve a tender medium-rare finish. When you flip the steak halfway through, add the pineapple spears and red bell pepper to the grill as well, letting them char for 3 minutes on each side. The combination of smoky, juicy steak, and grilled veggies will be irresistible.

Step 4: Rest the Steak and Veggies

Once grilled, transfer the steak, pineapple, and peppers to a clean cutting board and let them rest for 10 to 15 minutes. Resting is key to allowing the juices to redistribute throughout the meat, which keeps every slice perfectly moist and flavorful. This pause also lets the grilled fruit cool slightly, making it easier to handle for the salsa.

Step 5: Make Pineapple Salsa

While the steak rests, finely chop the grilled pineapple and bell pepper, then combine them in a bowl with the diced red onion, minced jalapeno, fresh lime juice, chopped cilantro, and a pinch of kosher salt. Stir everything together to meld the flavors into a vibrant, refreshing salsa that beautifully complements the smoky steak.

Step 6: Serve Your Grilled Flank Steak with Pineapple Marinade and Salsa Recipe

Thinly slice the steak against the grain—this is crucial for tenderness—and serve it alongside generous spoonfuls of the pineapple salsa. The contrast of savory, juicy steak and bright, sweet, and slightly spicy salsa creates a wonderfully balanced bite that’s hard to resist.

How to Serve Grilled Flank Steak with Pineapple Marinade and Salsa Recipe

Garnishes

For an extra pop of color and flavor, sprinkle fresh cilantro over the plated steak and salsa. A few lime wedges on the side allow guests to add extra zest if they desire. Toasted sesame seeds also make a beautiful finishing touch, adding a bit of crunch and nutty aroma.

Side Dishes

This steak pairs gorgeously with light, fresh sides that won’t overpower its distinct tropical flavors. A crisp green salad with avocado and cherry tomatoes works wonderfully, as does fluffy coconut rice or grilled corn on the cob brushed with herb butter. Each side dish complements the warm, sweet-savory character of the steak and salsa beautifully.

Creative Ways to Present

For effortless entertaining, consider serving the steak sliced over a bed of mixed greens with the pineapple salsa draped on top. Alternatively, use warmed tortillas to turn this into delightful steak tacos with a drizzle of creamy lime crema. Your guests will be wowed by the versatility and explosion of flavors!

Make Ahead and Storage

Storing Leftovers

Any leftover steak and salsa can be stored in airtight containers in the refrigerator for up to 3 days. Keep the salsa separate if possible to preserve its fresh texture, and store the sliced steak with its own juices for the best flavor.

Freezing

You can freeze the cooked steak by wrapping it tightly in plastic wrap and then placing it in a freezer bag. It’s best used within 2 months for optimal taste and texture. However, the pineapple salsa doesn't freeze well because the fresh ingredients tend to become watery when thawed.

Reheating

To reheat, gently warm the steak slices in a skillet over medium heat or in the oven wrapped in foil to prevent drying out. Refresh the pineapple salsa by stirring and adding a squeeze of fresh lime juice before serving again.

FAQs

Can I use other cuts of steak for this recipe?

Absolutely! While flank steak is ideal for this pineapple marinade and grilling method, skirt steak or flat iron steak are excellent alternatives and still deliver great flavor and tenderness.

What if I don’t have fresh pineapple juice?

No worries at all. You can use canned pineapple juice if fresh isn’t available. Just opt for the unsweetened variety if possible to avoid overly sweetening the marinade.

How spicy is the salsa?

The salsa has a mild kick from the jalapeno, which you can adjust or omit depending on your heat preference. Removing the seeds will also reduce the heat if you want a gentler flavor.

Can I prepare the marinade and salsa ahead of time?

The marinade can definitely be made ahead and stored in the fridge, but it’s best to add the steak just before marinating. The pineapple salsa is freshest when made close to serving, to maintain its bright texture and flavors.

What is the best way to slice flank steak?

Slice gently against the grain in thin slices to maximize tenderness. This breaks up the muscle fibers and results in a more tender bite every time.
