Cover with a drop lid and bring the mixture to a boil over high heat. Turn down the heat to maintain a gentle simmer and cook until the potatoes and carrots are tender (about 10 minutes). Gently stir the mixture together about halfway through cooking to ensure they're getting some time in the dashi.
Ideally, you want to cover the pot with a lid and let the nikujaga cool to room temperature once, which encourages the dashi stock to permeate every ingredient. If you don't have time, proceed to the next step.
Reheat the nikujaga before serving and steam the 80 grams snap peas on top of the other ingredients for about 1 minute covered with a lid.
