Flank Steak Peperonata
Peperonata—sweet peppers slowly stewed in olive oil—can take ages to prepare. We wanted a quick version to serve with steak for a weeknight supper.
Why This Recipe Works
Peperonata is a mixture of sweet peppers, onion, tomato, and garlic, cooked in fruity olive oil until the peppers are soft and the flavors have melded. In order to get the flavors of both to marry, we cut the flank steak with the grain into three equal pieces, and seasoned all sides with salt, pepper, and oregano, and wrapped it in plastic for up to 24 hours to fully season the meat. Then we cooked red and yellow bell peppers, onion, and garlic in a hefty amount of extra-virgin olive oil until softened, added diced tomatoes, capers, red pepper flakes, and cooked the mixture until the vegetables were softened. After wiping out the skillet, we seared the seasoned steak pieces on all sides to a perfect medium-rare. While the meat rested, we stirred fresh basil into the peperonata mixture. To serve, we sliced the meat into smaller pieces, against the grain, seasoned the sliced with salt and pepper and the accumulated meat juices, and arranged the meat over the peperonata. A drizzle of extra-virgin oil balanced the tangy, meaty flavors.
