How To Make Miso Shiitake Mushroom Onion Gravy

Shiitake mushrooms are so good and rich in flavor. Not only are they delicious they really help boost your immune system. So I like to eat them often and I put them in lots of dishes. I like whole fresh shiitake’s for most of my recipes. They let out a lot of liquid flavor when they are being cooked. I used a 4 oz. package of fresh whole shiitakes for this recipe.

The trick to this gravy is all in the miso. I find that the mellow white miso works best because it is so mild. Some miso’s are very strong and are over powering to other flavors. I like the traditional Japanese premium light miso brand called Miso Master Organic. Its the one you can see in my YouTube video right at the beginning. It is artisanal hand-crafted and Non GMO and gluten-free miso. In the YouTube video you can see that after you add the miso it needs to be broken down and stirred in with a spoon. Plus the miso will thicken the gravy. No corn starches here!

A vegetable broth can be so hard to pic. Often I get home and use a new brand just to find that it is watered down with hardly any flavor. That is why I like Trader Joe’s organic vegetable broth. It is rich in flavor and color. It also seems to be a little thick. I like this for my recipes. I want flavor! Plus, it is low in sodium so I can gage how much salt or miso I want in my dish.

What To Put Miso Shiitake Mushroom Onion Gravy On

This delicious gravy goes very well with old fashion mashed potatoes. Although, you can spread out the adventure and be very creative. I show in this picture above the Miso Shiitake Mushroom Onion Gravy on one of my last posted recipe creations of Vegan Miso Rutabaga Cauliflower Mash. These two are paired so great together. It would be a very nice Holiday side dish. This gravy would also be good on mixed Asian veggies, cooked bok choy, cabbage or any kind of rice or pasta. If it were rice or pasta maybe I would add a little sesame oil to it before topping it with the gravy.

There are so many different ways to explore using this gravy. This is one I will work some more with and see what I come up with. I hope you enjoy this wonderful umami rich gravy as much as we do.
