Introduction

Donkkaseu sauce (돈까스 소스) is the glossy brown sauce that Koreans pour over donkkaseu, a thin, wide, crispy pork cutlet. The dish came to Korea from Japanese tonkatsu, but Korea gave it its own personality: the cutlet is pounded flat, and instead of a thick dipping sauce on the side, it is often served drenched in a sweet, tangy, gravy-like sauce with cabbage salad, rice and a scoop of macaroni or corn. It is a classic of old-school gyeongyangsik (Korean-Western) restaurants, school cafeterias and lunch boxes.

What is Donkkaseu Sauce Made Of?

The Korean restaurant-style sauce starts with a light butter and flour roux. Ketchup, Worcestershire sauce, sugar and a little soy sauce are stirred in, then loosened with water, stock or milk until it is pourable like gravy. Some cooks add grated apple or onion for fruitiness. Japanese tonkatsu sauce, by contrast, is a thick, fruity bottled sauce used for dipping and is usually not cooked with a roux.

Types of donkkaseu sauce

• Gyeongyangsik (old-school) sauce: a thin, gravy-like brown sauce poured over the whole cutlet.
• Bottled donkkaseu sauce: ready-made sweet brown sauce sold at Korean markets.
• Japanese-style tonkatsu sauce: thick and fruity, served on the side with sesame seeds.
• Cream or curry sauce: newer café versions served over cheese or rolled cutlets.

What Does Donkkaseu Sauce Taste Like?

It tastes sweet first, then tangy from ketchup and Worcestershire, with a buttery, savory finish. It is gentle and kid-friendly, a bit like a cross between barbecue sauce and gravy. Poured over a hot cutlet, it softens the crust slightly at the edges while the center stays crisp.

Easy Donkkaseu Recipe (Serves 2)

Ingredients

• 2 boneless pork loin chops (about 5 oz / 150 g each)
• Salt and black pepper
• 1/3 cup all-purpose flour
• 1 egg, beaten
• 1 1/2 cups panko breadcrumbs
• Neutral oil for frying (about 1 inch / 2.5 cm in the pan)
• Shredded cabbage, rice and pickles to serve

Donkkaseu sauce

• 1 tbsp butter
• 1 tbsp all-purpose flour
• 3 tbsp ketchup
• 1 1/2 tbsp Worcestershire sauce
• 1 tbsp sugar
• 1 tsp soy sauce
• 3/4 cup (180 ml) water or chicken stock
• Pinch of black pepper

Instructions

1. Place each chop between plastic wrap and pound with a meat mallet or rolling pin to about 1/4 inch (6 mm) thick. Season both sides with salt and pepper.
2. Make the sauce: melt the butter in a small pan over medium-low heat, stir in the flour and cook 1–2 minutes until light brown. Whisk in the water or stock, then the ketchup, Worcestershire, sugar, soy sauce and pepper. Simmer 3–4 minutes until it coats a spoon. Keep warm.
3. Coat each cutlet in flour, then egg, then panko, pressing so the crumbs stick.
4. Heat the oil in a deep, heavy skillet to about 340–350°F (170–175°C). Fill the pan no more than halfway, keep the handle turned inward, and never leave hot oil unattended. Lay the cutlet in gently, away from you.
5. Fry 2–3 minutes per side until deep golden and the pork reaches at least 145°F (63°C) inside. Drain on a rack for 2 minutes.
6. Slice or leave whole, plate with cabbage and rice, and pour the warm sauce over the cutlet just before serving.

Tip: For extra-crisp cutlets, spray the panko lightly with water before frying, or use our twigim garu frying mix instead of plain flour.

Bottled sauce should be refrigerated after opening and used by the date on the label. Leftover fried cutlets can be refrigerated for 1–2 days and re-crisped in a 400°F (200°C) oven or air fryer.

Donkkaseu Sauce FAQ

Can I use bottled tonkatsu sauce?

Yes. Simmer it with a little water and a pat of butter to get closer to the Korean restaurant style.

No. Classic donkkaseu is mild, which is why it is a favorite with kids. Some shops offer a spicy version with gochugaru or chili sauce.
