- 1 cup milk (or unsweetened soy or oat milk) – Loosens and softens the mash while adding creaminess.
- ¼ teaspoon kosher salt – Enhances flavor.
- ¼ teaspoon ground black pepper – Adds subtle warmth.
For the Vegetable Japanese Curry
- 1 tablespoon vegetable or grapeseed oil – Neutral oil for sautéing vegetables.
- 3 oz (85 g) onion, diced – Provides sweetness and aromatic depth.
- 1.5 oz (45 g) carrot, diced – Adds natural sweetness and texture.
- 1.5 oz (45 g) frozen corn, thawed – Brings subtle sweetness and color.
- 2 oz (60 g) zucchini, diced – Contributes moisture and tender bite.
- 350–400 ml water – Forms the base of the curry sauce (adjust for thickness preference).
- 5 blocks Japanese curry roux (e.g., Vermont Curry) – Thickens and flavors the sauce with signature sweetness and spice.
- ⅓ cup spinach, finely chopped – Adds freshness and color at the finish.
Step-by-Step Instructions
Boil the Potatoes
Place chopped potatoes in a pot and cover with water by about 2 inches. Bring to a boil over high heat, then reduce to a simmer and cook for about 7 minutes, or until fork-tender.
Mash Until Smooth
Drain potatoes and return to the pot. Add butter, milk, salt, and pepper, then mash until smooth and creamy. Set aside, keeping warm.
Sauté the Aromatics
In a medium pot over medium heat, add oil and sauté diced onion and carrot for 2–3 minutes, until onions turn translucent.
Add Remaining Vegetables
Stir in corn and zucchini, cooking for another 2 minutes to soften slightly.
Build the Curry Sauce
Pour in 350–400 ml water and add the curry roux blocks. Stir continuously until fully dissolved and the sauce thickens to a bubbling, gravy-like consistency.
Finish with Spinach
Turn off the heat and stir in chopped spinach until wilted.
Assemble and Serve
Spoon creamy mashed potatoes into bowls and top generously with vegetable curry. Serve immediately while warm.
Recipe Notes & Tips
- Choose Starchy Potatoes – Russet or Yukon Gold provide the smoothest mash.
- Control Curry Thickness – Use less water for thicker curry, more for saucier consistency.
- Dissolve Roux Completely – Stir thoroughly to avoid lumps in the sauce.
- Don’t Overwork Potatoes – Over-mashing can make them gluey; mash just until smooth.
- Customize Vegetables – Add peas, mushrooms, or bell peppers for variation.
- Taste Before Salting – Curry roux already contains seasoning.

Why This Recipe Works
This recipe works because it balances creamy starch with thick, savory sauce. Japanese curry roux contains flour and fat, which melt and emulsify into the cooking liquid, naturally thickening the sauce while delivering layered sweetness and spice. The mashed potatoes provide a neutral, buttery base that softens the curry’s intensity and enhances its comfort-food appeal. Cooking vegetables briefly preserves texture while allowing their natural sugars to complement the curry’s sweetness. At approximately 414 calories per serving, this dish delivers hearty satisfaction while remaining balanced for a complete vegetarian meal.
