Gather all the ingredients. Once we start cooking, we don't have time to measure, so make sure to prepare the seasonings ahead of time.
Pat dry the chicken with paper towel to remove any moisture. Season the chicken with kosher salt and freshly ground black pepper.
Heat a crock pot and add oil. Brown the chicken, skin side down, for 5 minutes each side, or until golden brown. Don’t crowd the pot and brown the chicken in batches, if necessary.
After the bottom side is nicely brown, flip to cook the other side. Then transfer the chicken to a plate and continue with the next batch. Set aside.
Add the diced onion and 1 Tbsp unsalted butter. Sauté until translucent, about 7-8 minutes.
Add the garlic and ginger and mix all together.
Add Japanese curry roux, Curry powder, and Garam masala. Give it a quick stir.
Add Tomato paste and sauté until fragrant.
Add Honey and Mango chutney and mix all together.
Gradually add half the chicken broth, scraping the brown bits on the bottom of the pot. Transfer the chicken back to the pot.
Add the carrots, shimeji mushrooms, and the rest of chicken broth.
Add Dry basil and Bay leaf. Gently mix all together.
Add other vegetables.
Bring to a boil. Lower heat and close the lid. Cook for 45 minutes. Stir occasionally.
Once the vegetables are cooked is done, add soy sauce. Taste and adjust the flavor.
Serve the steamed rice in a small bowl or plate and the soup curry in a bowl. When you eat, pick up some rice with a spoon, and scoop soup curry. Enjoy!
