Ingredients

Today we’re using simple ingredients to make this vegan mushroom and onion gravy. Each one adds a layer of savory, umami flavor.

• Vegan Butter

• Yellow Onions

• Garlic

• White Button Mushrooms or Cremini Mushrooms

• White Miso Paste

• Soy Sauce

• Thyme

• All-purpose Flour

• Dairy Free Milk

• Vegetable Broth, or use a mushroom broth

Substitutions & Add-ins:

• Vegan Butter: while I recommend using vegan butter if possible, a good quality extra virgin olive oil can be substituted in its place.

• Miso Paste: if you don’t have miso, it can be omitted. White Miso can be subbed for Yellow Miso Paste.

• Cremini Mushrooms: sub in your favorite type of mushroom instead. Shiitake mushrooms would be delicious in this vegan mushroom gravy.

• Yellow Onions: sub in white onions, red onions, or shallots instead.

• Soy Sauce: sub in coconut aminos, vegan Worcestershire sauce or reduced-sodium soy sauce.

• Other herbs or spices: nutritional yeast, fresh rosemary, a bay leaf, or fresh sage would make a delicious addition to this vegan miso gravy.

• All-purpose flour: the ¼ cup of flour can be substituted for 2-3 tbsp of corn starch or corn flour.

The best vegan butter:

This mushroom and onion gravy uses a similar cooking method as my Vegan Oat Milk Bechamel recipe. The base of this gravy is a roux, which is a paste made from vegan butter and flour.

This helps to thicken up the gravy and create a creamy texture. While olive oil can be used, I’ve found that vegan butter adds needed saltiness and a richer flavor to the gravy.

Below are my favorite brands to use:

• Country Crock Plant Butter Sticks 
• Earth Balance Buttery Sticks

Step-by-step Instructions

🎥 *Video Tutorial is Above the Recipe Card Below!*

STEP 1: Over medium heat melt the vegan butter (or heat the olive oil) in a medium saucepan.

STEP 2: Add the onion, garlic, and mushrooms and saute for 7-10 minutes until tender and the onions have turned slightly golden brown. 

STEP 3: Add the miso, soy sauce, and sprinkle on the flour. Then, mix to evenly coat the veggies. Cook for 1 minute to remove the raw flour taste.

STEP 4: Reduce the stovetop to medium-low heat and pour in the dairy-free milk, ½ a cup at a time, stirring continuously. Then, pour the veggie broth in, ½ a cup at a time. 

STEP 5: Add the fresh thyme and simmer for 5 minutes on low heat to thicken the gravy. The gravy should be a creamy and thick yet pourable consistency.

Storing the Gravy

Transfer this vegan onion gravy to an airtight container and store it in the fridge for up to 3-4 days. 

📌 Note: if prepping this recipe ahead of time, as the gravy cools in the fridge or at room temperature it will thicken but will loosen up again once heated through. 

To prevent it from forming a ‘skin’ on top, place a sheet of plastic wrap on the gravy.

Pro Tips

• Use high quality ingredients: like most recipes that use less than 10 ingredients, it’s important to use high-quality ingredients for the best flavor.

• Slowly add the liquids while whisking: this will help prevent any flour lumps from forming.

• Cook the veggies until you have slightly caramelized onions: this adds lots of flavor.

• Adjust the seasoning to your liking: add in salt and black pepper to taste. You can also mix in any fresh herbs you’d like after the gravy is finished simmering.
