Croquetas de Jamón are a Cuban household staple! They're crispy, bite-size logs of smooth ground ham coated in breadcrumbs then fried to perfection. The perfect breakfast or snack for any day of the week!
In a saucepan, melt butter and cook the onions. Slowly whisk in milk, 1/3 cup of flour, nutmeg, salt, and pepper. Continue to whisk until it becomes a very thick sauce (a roux).
Remove the filling from the refrigerator. Form logs from the mixture straight from the fridge until you have all the logs done then place them back in the fridge to firm up once again, about 30 minutes.
Set up a breading station. Dip each croquette log in the egg wash and then coat in bread crumb mixture. Repeat with each one until they are all breaded. Let the croquettes rest at room temperature for 5 minutes before frying.
In a large pot or pan, heat oil. Fry each croquette until golden brown, approximately 3-4 minutes. Don’t crowd the pot too much as you are frying. Drain them on a paper towel-lined plate. Serve with saltines and limes.
