1 tablespoon neutral oil, like canola, vegetable or grapeseed
1 medium yellow onion, chopped into 1-inch pieces
1/2pound red or gold potatoes, chopped into 1-inch cubes
3 medium-large carrots, peeled and chopped into 1/2-inch-thick rounds
Optional: Protein of choice, like beef, chicken, shrimp or tofu, cut into bite-sized pieces if needed — I like to top mine with Chicken Katsu
1 block Japanese curry roux (broken into 4 pieces) — I prefer S&B Foods Hot
2 3/4cups water
Kosher salt
3 green onions, sliced, for topping
Cooked rice, for serving
Instructions
Heat the oil in a large, high-sided skillet or soup pot over medium-high heat. Once the oil is hot, add the onion and cook, stirring frequently, for about 4–5 minutes, or until the onion is beginning to turn soft and translucent.
If using a protein with a longer cook time, like beef or chicken, add it now and cook, stirring frequently, for another 5 minutes or so, or until the protein is browned on the outside.
Add the potatoes, carrots, a pinch of salt, and water. Cover the pot with a lid and bring to a boil, then reduce heat to medium-low. Simmer for 10–12 minutes, or until the potatoes and carrots are just barely fork-tender. If using a quick-cooking protein like shrimp or tofu, add it to the pot once the vegetables are nearly finished cooking.
Add the curry roux blocks to the pot and stir until the blocks have dissolved and the mixture is thickened. This should take about 3–4 minutes.
Serve with steamed rice and top with sliced green onion.
