Green Bean Casserole With Dashi Powder: Instructions

Step 1

Start by preheating your oven to 400 degrees. Grab a medium-sized bowl and fill it with ice water. Set it aside.

Step 2

Fill up a large pot with water and bring it to a boil. Add the green beans and let them cook for 3-4 minutes. Then drain the water and place the beans in the bowl of ice water to stop the cooking process.

Step 3

Grab a cast-iron skillet (12-inch or whatever similar size you have) and melt the butter in it over medium heat. Add the garlic, onions, and mushrooms and stir-fry them with a wooden spoon for about 4-5 minutes until the mushrooms are fragrant and the onions soften.

Step 4

Dissolve the miso in a small bowl in a cup of water. Whisk energetically until it is well dissolved.

Step 5

Add the soy sauce, sriracha, and dashi soup mix to the skillet. Stir for about a minute until all flavors are combined. Sprinkle some flour and cook for another minute. Then, add the dissolved miso and bring to a simmer, stirring frequently for 6-8 minutes until the mixture thickens.
