Adobo-Braised Flank Steak with Charred Scallion Chimichurri and Whipped Cumin Sweet Potatoes
Welcome to my kitchen. Today, we’re taking a cut that’s often overlooked—flank steak—and turning it into something that eats like a slow-braised luxury.
This dish is all about balance. You’ve got that deep, adobo-style braise layered with citrus and spice… paired with silky, cumin-kissed sweet potatoes… and finished with a bright, charred scallion chimichurri that cuts right through the richness.
This is how you take a humble cut and turn it into something that feels like a plated experience.
Prep Time: 35 minutes | Cook Time: 3 hours 30 minutes | Serve Size: 4
Ingredients
2 pounds flank steak, trimmed and cut into 3 large pieces
2 tablespoons vegetable oil
1 large yellow onion, sliced thin
6 cloves fresh garlic, smashed
2 whole dried ancho chiles, stems and seeds removed
2 cups beef stock
½ cup fresh orange juice
2 tablespoons tomato paste
1 tablespoon ground cumin
1 tablespoon chili powder
1 teaspoon dried oregano
2 teaspoons kosher salt
1 teaspoon cracked black pepper
2 large sweet potatoes, peeled and cubed
4 tablespoons unsalted butter
½ cup heavy cream
1 bunch fresh cilantro, finely chopped
½ bunch fresh flat-leaf parsley, finely chopped
3 scallions, charred in a dry pan and minced
¼ cup extra virgin olive oil
2 tablespoons red wine vinegar
1 fresh lime, zested and juiced
Method
Preheat oven to 300°F. Season flank steak generously with salt, pepper, cumin, and chili powder.
Heat vegetable oil in a Dutch oven over medium-high heat. Sear steak until deeply browned on both sides. Remove and set aside.
In the same pot, add sliced onion and cook until softened. Stir in garlic and tomato paste; cook 2 minutes until fragrant and slightly caramelized.
Deglaze with orange juice and beef stock, scraping up all the flavor from the bottom. Add ancho chiles and oregano. Return steak to the pot.
Cover tightly and transfer to oven. Braise for 3 to 3½ hours, until fork-tender.
Meanwhile, boil sweet potatoes in salted water until tender. Drain and mash with butter, heavy cream, and cumin until smooth and whipped.
In a bowl, combine olive oil, red wine vinegar, lime juice, lime zest, charred scallions, cilantro, and parsley to form chimichurri.
Remove beef from liquid. Strain braising liquid into a saucepan and reduce by half to create a rich adobo jus.
Plate with a base of whipped sweet potatoes, top with braised flank steak, spoon over reduced jus, and finish with chimichurri.
Chef Notes
Low and slow is everything here. Flank steak is naturally lean with strong muscle fibers, so giving it time at a gentle temperature allows it to break down properly. Also—don’t skip the reduction. That jus is where all your flavor lives.
Did You Know?
Flank steak is traditionally a quick-cooking cut, but when braised, it transforms completely—absorbing flavor while becoming incredibly tender, similar to short rib but with a lighter, cleaner finish.
Flavor Notes
This dish hits in layers. The adobo braise brings deep warmth from cumin, ancho chile, and tomato, balanced by subtle citrus from orange juice. The whipped sweet potatoes add natural sweetness and a creamy texture that softens the spice. Then the chimichurri comes in bright and sharp—lime, herbs, and charred scallions cutting through the richness and resetting your palate with every bite.
