Start by prepping your cube steak. Slice it into thin strips, then toss it with olive oil, vinegar, sazon, adobo, and oregano in a bowl. Mix everything well so the flavors soak into the meat. I recommend letting it marinate in the fridge for at least 2 hours, though overnight will take the flavor to the next level! 🕑
Heat your Dutch oven over medium heat and add a little olive oil. Start by cooking the sofrito until fragrant. Once your kitchen smells amazing (about a minute or two), add your marinated beef strips. Stir occasionally, allowing the meat to sear and brown slightly. 🍳
Now it’s time to add in the sliced onions, tomato sauce, water, and powdered bouillon. Give everything a good stir so the ingredients blend well, and bring the mixture to a gentle boil. 🍲
Reduce the heat to low, cover the pot, and simmer for 40-45 minutes. Allow the onions to soften and the beef to become fork-tender. Stir occasionally to make sure nothing sticks to the bottom of the pot. Once the stew is ready, the onions will practically melt into the sauce, creating a luscious gravy. 🍽️
Serve the bistec encebollado hot with a steaming bowl of white rice, fried plantains, or crusty bread. Don’t forget to spoon extra sauce on top for maximum flavor!
