Hidden Veg Katsu Curry Sauce – My Fussy Eater

A kid-friendly Katsu Curry Sauce packed with hidden vegetables. Brilliant for getting some added nutrition into your fussy eaters!

My daughter has really been getting into curries and more spicy food lately. It’s a brilliant step forward after years of rejecting them so I’m leaning into it as much as possible.

You know I’m a big fan of Hidden Veggie Recipes so I thought I would combine the two and make a Hidden Veg Katsu Sauce.

This recipe has four vegetables blended into the katsu sauce. Cauliflower, courgette, carrots and red peppers.

I did try out adding more veggies but I wanted to keep the flavour of the sauce as similar as possible to the original taste and this combo and quantity has worked out perfectly.

The first step is to make the base of the katsu curry by frying some onions and garlic in oil.

Add in garlic along with curry powder and flour.

The amount of curry powder you use will really depend on your child’s tolerance for spice. I used 2 tablespoon as my daughter likes a small amount of heat. There is a definite kick to the sauce but it’s not super spicy.

However if your kids prefer a much milder sauce then try it initially with only 2 tablespoon of curry powder.

Add in honey, soy sauce and stock, along with the chopped veggies.

Bring to the boil and then simmer for 20 minutes until the veg has cooked.

Blitz the sauce until it is completely smooth.

You can either use a hand blender directly in the dish or transfer into a stand blender.

I served the sauce up with a tempura battered chicken fillet, rice and some veggies on the side.

You can either serve the sauce in it’s own separate bowl like I have, or pour it over the chicken and rice, whatever your kids prefer.
