Start by peeling the russet potatoes. Once peeled, chop them into even-sized cubes to ensure they cook evenly. Place the cubed potatoes in a large pot and fill it with water until the potatoes are submerged. Add a pinch of salt to the water for flavor.
Bring the pot of water to a boil over medium-high heat. Once boiling, reduce the heat to medium and let the potatoes cook for 15-20 minutes or until they are fork-tender. Drain the potatoes and return them to the pot.
Using a potato masher, mash the potatoes until smooth. Season with salt and pepper to taste. If you want to add a little extra flavor, consider mixing in some spices like cumin or chili powder. Once seasoned, fold in the shredded queso fresco until well combined.
In a large skillet, heat about ΒΌ cup of vegetable oil over medium heat. While the oil is heating, wrap the corn tortillas in a damp paper towel and microwave them for about 30 seconds to warm them up. This will make them pliable and easier to work with.
Once the tortillas are warm, place a generous spoonful of the potato and queso fresco filling in the center of each tortilla. Fold the tortillas in half to create a taco shape.
Carefully place the filled tacos in the hot oil, frying them for about 2-3 minutes on each side or until golden brown and crispy. Remove the tacos from the skillet and place them on a paper towel-lined plate to absorb any excess oil.
Serve your potato tacos warm with your favorite toppings. Some great options include fresh cilantro, diced onions, salsa, or avocado slices. Enjoy the crispy, cheesy goodness with friends and family!
