Tostones Rellenos, ¡que rico! Just picture plantains fried not once, but twice, shaped like cups, and stuffed with your favorite fillings like vaca frita (shredded beef), Cuban picadillo, ropa vieja, or shrimp. The possibilities are endless! Crispy on the outside, soft on the inside, and made in 20 minutes from start to finish.
Peel and cut the plantains into 2-inch pieces. You should have 3-4 pieces per plantain.
In a large pot, pour enough oil to cover the plantains. Heat oil over medium-high heat to 400ºF. Fry the plantain pieces in the hot oil for about 5 minutes. Drain on a paper towel-lined plate.
Using a lemon squeezer or a wooden block, press down on the plantain piece so it looks like a small cup. Remove carefully. Set aside.
Fry the cups again in the hot oil until golden brown, about 3-4 minutes. Drain on a paper towel-lined plate. Season with salt.
Fill each toston cup with your favorite filling such as vaca frita, shredded chicken, picadillo, or shrimp. Garnish with chopped parsley, if desired. Enjoy!
