Add oil to a small sauce pan, large enough to fit a whole corn tortilla. Heat over medium until oil is shimmering.
Using tongs, gently place a corn tortilla in the pan. Wait 5-10 seconds and flip. Wait an additional 5-10 seconds and remove from pan letting any excess oil drip off into pan. Place on a small plate to cool and repeat with remaining tortillas. Tortillas should be soft and pliable at this point.
In a 9x9 square baking dish, add 1/4 cup of sauce on the bottom.
Take one of your softened corn tortillas, dip it into your sauce covering both sides (I find using your hands for this to be the easiest method to avoid tearing).
Place tortilla into baking dish, sprinkle a line of cheese down the center, and roll the tortilla like a burrito, making sure to place the enchilada seam side down. Repeat with remaining tortillas until all have been filled and rolled.
Gently spoon all remaining sauce over enchiladas, make sure to evenly distribute.
Sprinkle the potato topping mixture over the enchiladas. Sprinkle cheese lightly over the potatoes.
Bake at 375 degrees for 45 minutes until bubbly and cheese is lightly toasted.
