This Peruvian steak recipe brings the bold flavors of Peru to your kitchen with aji amarillo butter, crispy edges, and tender, juicy meat.
The secret lies in marinating the steak in a vibrant blend of aji amarillo—Peru's signature yellow chili—and finishing it with a rich, herby butter that locks in flavor. I first discovered this technique during a trip to Lima, where street vendors transformed simple cuts into unforgettable meals.
The recipe begins with a simple marinade of aji amarillo paste, garlic, and lime juice, which tenderizes the meat while infusing it with smoky, slightly sweet heat. Grilling or pan-searing the steak over high heat ensures those crispy edges we all crave, while the butter basting adds a velvety finish.
This method works beautifully with flank steak or skirt steak, both of which are perfect for slicing thinly against the grain.
What you’ll end up with is a dish that’s rich, aromatic, and packed with layers of flavor—think caramelized edges, tender meat, and a sauce that’s both tangy and creamy. The aji amarillo adds a depth that sets this steak apart from traditional preparations, making it a standout for any dinner.
Serve it with classic Peruvian sides like papa a la huancaína or a fresh salad to complete the meal.
Ready in about 30 minutes, this recipe is perfect for weeknight dinners or special occasions when you want to impress. The key is patience—letting the marinade work its magic and cooking the steak just right. Once you try this, you’ll never go back to plain grilled steak again.
Ingredients for peruvian steak
Bold flavors start with these 12 ingredients—aji amarillo, crispy edges, and tender meat.
| Ingredient | Amount | Notes |
|---|---|---|
| Flank Steak 🥩 | 1 ½ lb | Thinly sliced against grain |
| Aji Amarillo Paste 🌶️ | ¼ cup | Peruvian yellow chili paste |
| Garlic Cloves 🧄 | 6 cloves | Minced, fresh preferred |
| Lime Juice 🍋 | ¼ cup | Freshly squeezed |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for basting |
| Fresh Cilantro 🌿 | ¼ cup | Chopped, stems removed |
| Olive Oil 🫒 | 2 tbsp | For searing |
| Kosher Salt 🧂 | 1 ½ tsp | For seasoning |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked |
| Red Wine Vinegar 🍷 | 1 tbsp | For brightness |
| Fresh Thyme Leaves 🌿 | ⅛ cup | Chopped, optional |
| Vegetable Oil 🫒 | 1 tbsp | High smoke point |
The aji amarillo paste is the heart of this dish—look for authentic Peruvian brands like La Costeña or Pisco at Latin markets or well-stocked grocery stores. If you can't find it, yellow bell pepper paste (blended with a pinch of smoked paprika) works in a pinch, but it won't have that signature depth. Flank steak is ideal here—thinly sliced against the grain for tender bites. Buy it fresh from the butcher if possible, or grab it pre-sliced from the meat counter. The butter matters too—European-style (like Plugrá) melts cleaner than American butter, but regular unsalted works fine if that's what you've got.
No aji amarillo? Mix 1 tbsp yellow bell pepper paste with 1/2 tsp smoked paprika and 1/2 tsp sugar for a decent stand-in. Fresh cilantro hating you? Substitute 1 tbsp chopped parsley—it won't be the same, but it'll work. The lime juice can be bottled, but fresh is brighter. If you're feeling fancy, add a pinch of Peruvian ají panca (dried red chili) to the marinade for extra heat. The thyme is optional but adds a nice herbal note—dried works at half the amount. For the oil, avocado oil has the highest smoke point if you're searing.
Marinate the steak for at least 30 minutes—overnight is even better. The paste keeps in the fridge for 3 months once opened, so buy extra. Store the cilantro wrapped in damp paper towels in a bag for 5 days. The butter basting is where the magic happens—keep it cold until the last minute. Leftovers? Reheat gently in a skillet with a splash of water to keep everything juicy. This reheats beautifully—3-4 days in the fridge, 3 months frozen.

Step-by-step instructions for aji amarillo butter steak
Here's how to create restaurant-quality Peruvian steak with tender meat and crispy edges every time.
Prepare the Steak and Marinade Base
Begin by slicing the 1.5 lb flank steak thinly against the grain into ¼-inch thick strips. This ensures each bite will be tender. Place the sliced steak in a bowl and set aside.
In a separate small bowl, whisk together the 0.25 cup aji amarillo paste, 0.25 cup lime juice, 1 tbsp red wine vinegar, 0.125 cup fresh thyme leaves, 1.5 tsp kosher salt, and 1 tsp ground black pepper. This vibrant marinade will infuse the steak with authentic Peruvian flavors while keeping it juicy. Let it sit at room temperature for 10 minutes while you prepare the butter mixture.
Create the Signature Aji Amarillo Butter
In a small saucepan, melt the 0.5 cup unsalted butter over low heat. Once melted, remove from heat and stir in the 6 cloves minced garlic and 0.25 cup chopped fresh cilantro. Let this mixture cool slightly while you sear the steak.
The butter should maintain its golden color but not brown. If you see it turning pale, return it to very low heat for just 10 seconds to restore color. This butter will become your steak's luxurious coating and finishing sauce.
Sear the Steak to Crispy Perfection
Heat 1 tbsp vegetable oil in a large skillet over medium-high heat until shimmering. Add the sliced steak in a single layer, being careful not to overcrowd. Sear for 1-2 minutes per side until the edges develop a deep golden brown crust and the steak reaches medium-rare (about 130°F internal temperature).
This high-heat searing creates the crispy edges you're after while keeping the interior tender. Don't walk away—constant attention prevents burning. When the steak is nearly done, add the 2 tbsp olive oil to the pan to help baste the meat.
Finish with Aji Amarillo Butter
Remove the steak from the pan and transfer it to a warm serving platter. Immediately pour the cooled aji amarillo butter mixture over the steak, letting it coat each piece generously. The butter will melt slightly from the residual heat, creating a glossy finish.
Let the steak rest for 3-5 minutes before serving. This resting period allows the juices to redistribute, ensuring each bite remains moist and flavorful. The crispy edges will maintain their texture while the interior stays perfectly tender.
Garnish and Serve Immediately
Just before serving, sprinkle the steak with additional chopped fresh cilantro for brightness and freshness. The contrast between the crispy edges, tender meat, and vibrant sauce makes this dish truly special.
Serve immediately with your choice of sides—Peruvian-style fried potatoes or a simple green salad work beautifully. The steak should be served while still warm to enjoy the perfect combination of textures and flavors.
Pro Tips For Making Peruvian Steak
- SEAR FIRST, SAUCE LATER: Flank steak needs a hot pan—cast iron if you’ve got it—to build that crust before you even think about adding the aji amarillo. I learned this the hard way: if you toss in the paste too soon, you’ll end up with steamed meat instead of caramelized edges. Get the pan screaming hot, sear 2-3 minutes per side, then pull it out and let it rest while you make the sauce.
- GRATE THE GARLIC: Whole garlic cloves in this dish? Nah. Grate it—just a teaspoon or two—so it melts right into the butter and aji amarillo. I used to smash it with the flat of my knife, but grated garlic turns the sauce silky instead of chunky. (And yes, even if you’re impatient like me, take the 30 seconds to grate it.)
- DON’T SKIP THE REST: Flank steak’s tough when hot, so resist the urge to slice it right off the pan. Tent it with foil and let it sit for at least 5 minutes—10 if you can wait. I know, I know, but cutting it early turns it chewy. The meat reabsorbs juices while it rests, and that’s when it gets tender.
- USE THE LIME JUICE LAST: Add the lime juice right before serving, not while cooking. The acid breaks down the butter and aji amarillo if you mix it in too early, turning your rich sauce into a sad, separated mess. A quick squeeze at the end keeps the sauce bright and cohesive—trust me, your future self will notice.
Storing and reheating your peruvian steak
Refrigerator Storage
Store your leftover aji amarillo butter steak in an airtight container with a splash of aji amarillo marinade (about 2 tbsp) to keep it moist.
The steak stays fresh in the fridge for 3-4 days—I like to portion it into single-serving containers so I can reheat just what I need. Keep it covered with plastic wrap pressed directly on the surface to prevent drying. 🌡️
Freezer Prep
For longer storage, freeze the steak in a single layer on a parchment-lined tray for 1 hour before transferring to a freezer bag. This prevents clumping.
Label with the date—it keeps for 3 months without losing flavor or texture. When ready to eat, thaw overnight in the fridge for even reheating.
Reheating in Skillet
My favorite method is reheating in a cast-iron skillet over medium-low heat. Add 1 tbsp vegetable oil and a splash of water (about 2 tbsp) to the pan. Place the steak strips in a single layer and cover with a lid for 3-4 minutes, stirring occasionally.
The residual butter will remelt, giving it that restaurant-quality finish again. 🔥
Microwave Method
For quick meals, use the microwave on 50% power for 1-2 minutes total, stirring halfway. Add 1 tbsp water to prevent drying—this keeps the butter from separating. Cover with a damp paper towel to trap steam. The texture won't be as crispy, but it's still delicious for a fast lunch.
Grill Reheat Hack
If you have a grill, fire it up to medium heat and place the steak strips directly on the grates. Close the lid and let them cook for 2-3 minutes, flipping once.
This gives you those crispy edges back while keeping the inside juicy. Perfect for a quick weekend brunch!
Serving Leftovers
Leftovers make great tacos or bowls—just slice the reheated steak thinly and serve with Peruvian rice, black beans, and avocado. The aji amarillo flavors hold up beautifully in these dishes.
I also love using it in breakfast burritos with scrambled eggs and cheese for a flavor-packed start to the day. 🌯

Frequently asked questions
What's the best cut of steak for this Peruvian recipe?
Flank steak or skirt steak work perfectly—they're flavorful, affordable, and slice beautifully against the grain. For a more tender option, ribeye or sirloin also pair well, though they'll cost more. The key is cutting thin strips (¼-inch thick) to ensure tenderness.
Can I make this without aji amarillo paste?
Yes! Mix 1 tbsp yellow bell pepper paste with ½ tsp smoked paprika and ½ tsp sugar for a substitute. For extra depth, add a pinch of ají panca (Peruvian red chili). The flavor won't be identical, but it'll still taste delicious—just slightly milder.
How do I get the perfect crispy edges?
Sear the steak in a hot skillet with just 1 tbsp oil over medium-high heat for 1-2 minutes per side. Don't overcrowd the pan—work in batches if needed. The high heat creates a golden crust while keeping the inside tender. Finish with the aji amarillo butter immediately after searing.
What sides pair best with this steak?
Classic Peruvian sides like papa a la huancaína (cheesy potato dish) or rocoto relleno (stuffed spicy peppers) complement the flavors perfectly. For simplicity, try fried potatoes with a side salad or Peruvian rice (arroz con pollo). The aji amarillo butter's richness balances lighter sides.
Why does my steak turn out dry?
Overcooking is the most common cause—steak should reach 130°F (medium-rare) for juiciness. Also, slicing against the grain is critical. If you skipped marinating, try soaking the steak in cold water with lime juice for 30 minutes before cooking. Never skip the 3-5 minute rest before serving!
