Flank Steak Burrito with Avocado Dip

The move here is the two-stage beef treatment. Flank steak first poaches gently in seasoned chicken broth with bay leaf, white onion, and peppercorns until tender. Then it’s cooled, julienned into thin strips, and sautéed a second time with red onion, jalapeño, garlic, and tomatoes. That double cooking technique is common in Mexican home kitchens and produces meat that’s fork-tender on the inside with pan-seared edges on the outside.

The filling gets its Mexican character from cumin seeds (not ground cumin) and diced olives. Whole cumin seeds pop and release oils during the sauté, adding a warmer, nuttier depth than pre-ground powder. Olives sound odd in burritos but they’re traditional in Sinaloa and Sonora-style fillings, adding salty-briny pockets throughout.

This is built for entertaining. A party-sized batch, and the filling holds well in the fridge for a few days, letting you prep ahead and reheat as guests arrive.

Kitchen Tips

• Cool the flank steak completely before slicing. Hot meat shreds; cool meat julienenes cleanly.
• Always cut flank against the grain. Cross-grain cuts give short fibers instead of long stringy ones.
• Toast the cumin seeds briefly in the oil before adding other ingredients. Toasting doubles the flavor output.
• Warm the tortillas before filling. Cold tortillas crack when folded; warm ones roll smoothly.

Variations

• Swap flank for skirt steak, which has even more beefy flavor.
• Add a handful of cooked black beans or rice to the filling for a bulkier burrito.
• Top with queso fresco or crumbled cotija for extra cheese.
