Season the beef Milanesa steaks with salt and pepper on both sides.
In a shallow dish, place the flour. In another dish, beat the eggs. In a third dish, spread out the breadcrumbs.
Dip each steak into the flour, evenly coating both sides.
Next, dip the floured steak into the beaten eggs, allowing any excess to drip off.
Coat the steak with breadcrumbs, pressing them onto the surface to ensure a good coating.
Heat vegetable oil in a large skillet or frying pan over medium-high heat. You'll want enough oil to submerge the Milanesa halfway. To check if the oil is hot enough, drop a small breadcrumb into it; if it sizzles and bubbles, it's ready.
Carefully place the breaded Milanesa steaks into the hot oil. Fry for 2-3 minutes on each side or until golden brown and crispy. Remove them from the oil and place them on paper towels to drain any excess oil.
