This classic Cuban Steak Palomilla recipe begins with tender top round steak that is marinated in Caribbean seasonings and lime juice before being seared on a Blackstone or griddle and topped with seasoned sautéed onions.
If not already tenderized, place the steaks between two pieces of parchment paper and tenderize with a meat mallet until the steaks are about ¼ inch thick.
Place the steaks in a shallow dish and season both sides with the Sazon and Adobo seasoning.
Top the steaks with the thinly sliced onion and then season with the fresh lime juice. Marinate for at least 30 minutes, or up to overnight.
When you are ready to cook, preheat your Blackstone or griddle over medium-high heat (about 400 degrees). Oil the surface with cooking oil, like avocado oil.
Grill the onions for about 3 minutes until softened.
Next cook the steaks for about 2-4 minutes per side, until cooked to your desired doneness.
Remove the steaks and onions from the griddle and allow to rest for a few minutes. Plate the steaks and top with the sautéed onions.
