Steak and Onion Mini Sammies
A Puerto Rican-inspired twist, this recipe transforms beef loin into tender, flavorful Bistek Encebollado sandwiches. Slow-roasted, marinated in olive oil, vinegar, and citrus, it's cooked fat-side up for juiciness, then thinly sliced onto toasted gluten-free baguettes. Sauteed onions add depth, while crisp lettuce and tomatoes balance the flavors. Perfect for game day or anytime you crave a bold, satisfying sandwich!

- Preheat your oven to 250°F.
- Pat the beef loin roast dry with paper towels and place it in a glass dish.
- In a blender or food processor, combine olive oil, vinegar, and lemon juice. Blend for 45-60 seconds until emulsified.
- Slice two onions and set them aside.
- Liberally sprinkle Adobo seasoning over all sides of the roast.
- Pour the olive oil mixture over the roast and cover it with the sliced onions.
- Cover the dish and marinate for at least 4 hours or overnight in the refrigerator.
- Halfway through marinating, flip the roast and cover the other side with onions.
- Remove the roast from the refrigerator 1 hour before cooking to bring it to room temperature.
- Remove the roast from the marinade and onions, then place it in a roasting dish fat-side up. This allows the fat to render and keep the meat juicy while cooking.
- Transfer the roast to the middle rack of the oven and cook for 1 hour, or until the internal temperature reaches 120°F.
- Once it reaches 120°F, remove it from the oven and let it rest for 45-60 minutes.
- After resting, set your oven to broil and return the roast to the oven for 5-10 minutes, until the top browns slightly with a bit of char.
- Remove the roast from the oven and trim off any excess fat from the top or bottom.
- Slice the beef against the grain into 1/4-inch thin slices for tender bites.
- While the beef rests, heat a large pan over medium heat.
- Once hot, transfer the onions and marinade liquid into the pan.
- Cook, stirring occasionally, until the onions are soft and translucent, about 25 minutes.
- Remove the onions and set them aside in a bowl. Reserve the leftover oil in the pan.
- While the onions cook, thaw the baguettes if needed.
- Cut the baguettes lengthwise and lay them open.
- Spread the reserved olive oil from the pan on the cut sides of the baguettes.
- Bake the baguettes open-faced in a 400°F oven for 6 minutes, then remove and let them cool.
- Thinly slice the lettuce and tomatoes to prepare for assembly.
- Spread a thin layer of mayonnaise and mustard on one side of the baguette.
- Place sliced beef onto the bottom half of each roll.
- Top generously with the sautéed onions.
- Add the sliced lettuce and tomatoes.
- Place the top half of the baguette over the filling.
- Slice into finger sandwiches about 1.5-1.75 inches wide.
- Serve and Enjoy!
