Season pork on both sides with salt and pepper.
Dredge in flour, dip in beaten egg, then coat thoroughly with panko breadcrumbs.
Heat oil in a deep pan and fry the pork on medium heat until golden and crispy, about 4–5 minutes per side.
Remove and let rest on paper towel.
In a separate pot, heat 1 tbsp oil and sauté onions until fragrant.
Add carrots and potatoes, sauté for 2–3 minutes.
Pour in water and bring to a boil. Reduce to simmer and cook until vegetables are tender (10–12 minutes).
Break curry roux into pieces and stir into the pot. Simmer until thickened.
Slice pork and serve over rice with a generous ladle of curry.
