How to Make Japanese Katsu Bowls with Tonkatsu Sauce
Step-by-Step Instructions
Prepare the Tonkatsu Sauce:
- In a small bowl, whisk together ketchup, Worcestershire sauce, soy sauce, oyster sauce, Dijon mustard, and honey until smooth. Set aside.
Prepare the Katsu: 2. Pat lamb cutlets dry with paper towels and season both sides with salt and pepper. 3. Set up three shallow dishes: flour in the first, beaten egg in the second, and panko breadcrumbs in the third. 4. Dredge each cutlet in flour, shaking off excess, then dip in beaten egg, and finally coat thoroughly with panko breadcrumbs, pressing gently to adhere.
Cook the Katsu: 5. Heat vegetable oil in a large skillet over medium-high heat until shimmering. 6. Carefully place breaded cutlets in the hot oil and fry for 3-4 minutes per side until golden brown and cooked through (internal temperature should reach 145°F for lamb). 7. Transfer to a paper towel-lined plate to drain excess oil.
Assemble the Bowls: 8. Divide cooked rice between two bowls. 9. Slice the katsu cutlets and arrange over rice. 10. Drizzle generously with tonkatsu sauce. 11. Top with shredded cabbage, sliced green onion, and sesame seeds.
Helpful Tips
For Perfect Panko Coating: Use day-old panko breadcrumbs for extra crispiness, or toast fresh panko in a dry pan for 2-3 minutes before using. Press the breadcrumbs firmly onto the meat to ensure they stick well during frying.
Oil Temperature Control: Maintain oil temperature around 350°F. If the oil is too hot, the coating will burn before the meat cooks through. If too cool, the coating will absorb excess oil and become soggy.
Meat Preparation: For even cooking, pound the lamb cutlets to an even thickness of about ¾ inch. This ensures the meat cooks evenly and prevents the coating from burning.
Sauce Consistency: If your tonkatsu sauce is too thick, thin it with a tablespoon of water. If too thin, let it sit for a few minutes to thicken naturally.

Notes

- Meat Substitutions: While this recipe uses lamb cutlets, you can substitute with pork cutlets, chicken breast, or even firm tofu for a vegetarian version.
- Make-Ahead Option: The tonkatsu sauce can be made up to 3 days in advance and stored in the refrigerator.
- Serving Suggestions: Serve with miso soup and pickled vegetables for a complete Japanese meal experience.
- Oil Reuse: The frying oil can be strained and reused 2-3 times for similar recipes if stored properly in the refrigerator.
Frequently Asked Questions
Q: Can I bake the katsu instead of frying? A: Yes, you can bake the breaded cutlets at 400°F for 12-15 minutes, flipping halfway through. While not as crispy as fried, it’s a healthier alternative.
Q: What if I don’t have panko breadcrumbs? A: Regular breadcrumbs work, but panko creates a lighter, crispier coating. You can make panko-style crumbs by processing day-old white bread in a food processor.
Q: How do I know when the oil is ready for frying? A: Drop a small piece of breadcrumb into the oil. If it sizzles immediately and rises to the surface, the oil is ready.
Q: Can I make this recipe gluten-free? A: Substitute all-purpose flour with rice flour or gluten-free flour blend, and use gluten-free panko breadcrumbs. Check that your soy sauce is gluten-free.
Q: What’s the difference between katsu sauce and tonkatsu sauce? A: They’re essentially the same thing. Tonkatsu sauce is specifically designed for pork cutlets, but the flavor profile works well with any breaded and fried protein.
Storage Instructions
Refrigerator Storage: Store leftover katsu in the refrigerator for up to 3 days in an airtight container. Keep the sauce separate from the rice and vegetables to prevent sogginess.
Reheating: To maintain crispiness, reheat katsu in a 350°F oven for 5-7 minutes rather than using the microwave. The rice can be reheated in the microwave with a splash of water.
Freezing: Cooked katsu can be frozen for up to 1 month. Wrap individual portions in plastic wrap and place in freezer bags. Thaw overnight in the refrigerator before reheating.
Sauce Storage: Homemade tonkatsu sauce keeps in the refrigerator for up to 1 week in a sealed container.
