5-Minute Katsu Sauce
This katsu sauce comes together in 5 minutes with just a handful of ingredients. It’s tangy, savory, and just sweet enough to balance out crispy tonkatsu or chicken katsu.
You’ll never need the store-bought bottle again. A few whisks in one bowl and it’s ready to dip.
What Makes This Sauce So Good
This katsu sauce is the kind of condiment that saves a meal. It’s thick and glossy, with a tangy-sweet flavor that cuts through fried food without weighing it down.
The Worcestershire and soy sauce give it a savory depth that tastes like it simmered all day, but the whole thing comes together in one bowl. I always make a double batch.
Ingredients
- 1/4 cup ketchup: use a thick, full-flavored brand like Heinz
- 2 tablespoons Worcestershire sauce: gives the sauce its signature umami tang
- 1 tablespoon soy sauce: light soy or tamari for gluten-free
- 2 teaspoons granulated sugar: just enough to round out the tang
- 1/2 teaspoon garlic powder: adds a quiet savory note
Variations / Substitutions
- Sugar: use honey or maple syrup for a milder sweetness; the sauce will be a little runnier
- Soy sauce: tamari keeps it gluten-free; coconut aminos is a soy-free alternative
- Garlic powder: swap in 1 small grated garlic clove for a sharper bite
- Heat: stir in a pinch of cayenne or a few dashes of hot sauce if you like a little warmth
For a classic weeknight dinner, serve it with crisp pan-fried tonkatsu.
How To Make Katsu Sauce
Step 1: Whisk the Sauce
In a small bowl, combine the 1/4 cup ketchup, 2 tablespoons Worcestershire sauce, 1 tablespoon soy sauce, 2 teaspoons sugar, and 1/2 teaspoon garlic powder. Whisk until the sugar dissolves and the sauce turns glossy, about 1 minute.
Step 2: Adjust the Flavor
Taste the sauce and tweak it to your liking. If it’s too tangy, add an extra 1/2 teaspoon of sugar; for deeper umami, a splash of soy sauce; for more kick, a dash of Worcestershire. Stir again for about 30 seconds to incorporate.
Step 3: Spoon and Serve
Spoon the katsu sauce into a small bowl and serve it alongside hot, crispy tonkatsu. The sauce clings to each bite, so you don’t need much.
A Few Tips Before You Start
- This sauce tastes even better after 15 to 20 minutes of resting so the flavors have time to blend. Stir it again before serving.
- The sauce thickens slightly in the refrigerator. If it gets too thick, let it come to room temperature or stir in a teaspoon of water to loosen it.
- Make a double batch and keep it in a sealed jar in the fridge for up to a week. It’s fantastic on burgers or as a dipping sauce for fries.
Scale it up for a crowd:
| Amount | Ketchup | Worcestershire | Soy sauce | Sugar | Garlic powder |
|---|---|---|---|---|---|
| 1/2 cup | 1/4 cup | 2 tbsp | 1 tbsp | 2 tsp | 1/2 tsp |
| 1 cup | 1/2 cup | 1/4 cup | 2 tbsp | 1 tbsp + 1 tsp | 1 tsp |
Storing Leftover Katsu Sauce
- Refrigerate: Store in an airtight container for up to 1 week.
- Serve Cold: This sauce tastes great straight from the fridge or at room temperature.
What to Serve With Katsu Sauce
This sauce is made for crispy tonkatsu, but it’s just as good with chicken katsu or even fried shrimp. A drizzle over a rice bowl with shredded cabbage and sliced pork makes a fast meal.
The tangy-sweet flavor cuts through rich fried food, so don’t be shy about adding it to sandwiches or burgers.
Frequently Asked Questions
Can I use this as a marinade for chicken or pork?
Yes, this sauce works well as a quick marinade. Toss the meat in the sauce and let it sit for 30 minutes before grilling or pan-frying; it adds a tangy-sweet crust.
Is katsu sauce supposed to be thick or thin?
It’s naturally thick and glossy from the ketchup. If you prefer it thinner, stir in a teaspoon of water or a little extra Worcestershire sauce.
What can I use instead of Worcestershire sauce?
You can substitute 2 tablespoons of a mix of vinegar and molasses (1 tbsp each) plus a pinch of anchovy paste or fish sauce, but the flavor won’t be identical. Worcestershire is key for that tangy-savory backbone.
Can I freeze leftover katsu sauce?
Yes, it freezes well for up to 2 months in a sealed container. Thaw overnight in the fridge and stir before serving.
