Rellenos de yuca or stuffed cassava are a delicious appetizer that can be found at kiosks all over Puerto Rico. They are similar to rellenos de papa (stuffed potatoes) and can be filled with beef or cheese. This traditional Caribbean fritter is simple to make and is a crowd pleaser. Serve with avocado crema o cilantro lime sauce to take this appetizer to another level. Save this recipe for the next time you host a party, event, holiday or family gathering.

What is yuca?
Yuca, or cassava, is a root vegetable that can be compared to a white potato. Yuca has a rough, bark-like exterior and a dense, starchy, white interior. But its texture is stretchier and gummier than potatoes.
Yuca can be considered healthier than a potato due to its lower glycemic index, which leads to a slower, steadier release of energy, and its high fiber and vitamin c content. I personally love yuca, and I’d choose yuca over potatoes any day!

Rellenos de yuca ingredients:
- Cassava (yuca), fresh or frozen
- Milk
- Mantequilla
- Adobo
- Sazón
- Egg
- Flour
- Picadillo or cheese

How to make rellenos de yuca:
Cook cassava
Place a large pot of water over high heat. Bring to a boil and add 1 tbsp of salt. Peel and cut the cassava into small chunks. Make sure to cut the pieces about the same size so they can cook evenly. Add cassava to the boiling water and cook for 35-40 minutes or until fully cooked through and very soft in texture. I like to boil it for a long time to make sure it gets very soft.
Make Dough
Strain the cassava, remove the core and discard. Place the cassava in a large mixing bowl. Add milk, butter, salt or abodo, and sazón. Mash the cassava using a fork or potato masher until it’s smooth. To form the balls, rub a small amount of oil onto your hands. Use an ice cream scoop to make sure each ball is the same size.
Place the mixture on the palm of your hand and form a disc. Fill the center with beef (picadillo.) or cheese. Then close the ball by pulling the edges in. Add a tiny bit more of the mixture to seal the ball, if necessary. Roll the balls until smooth and perfectly round. TIP: Smooth any bumps with a tiny bit of oil on your fingertips. Repeat until you have used all the mixture. It should yield about 12-14 balls.
Coat the balls
Beat the egg and dip each ball in the egg and then into flour. Shake off the excess. Place the balls in the freezer for about 2-4 hours. You can also freeze them in an air-tight container for up to 3 months.
Fry at 325℉ in a deep fryer or large pot filled with enough oil to cover the balls completely. Cook until golden brown. TIP: Be careful not to overcook them or allow the oil to get too hot because they can burst.

Place them on a paper towel lined rack to cool and soak excess oil. Serve while hot and enjoy. ¡Buen provecho!
