In a skillet, over medium heat, melt the butter, then whisk in the flour 1 Tbsp at a time. Once all flour has been whisked in, cook for one minute to get rid of the raw flour. Use 6 Tbsp of flour for a thicker gravy, 4 for a thinner one.
Dissolve mushroom seasoning or nutritional yeast into the vegan beef / veggie broth. Whisk in the broth about 1/2 cup at a time until the gravy is about as thick as you'd like. Add the browning sauce and vegan Worcestershire.
Whisk to combine and then reduce and thicken to desired consistency. Taste and adjust for seasoning. Keep warm on low. If it gets to thick, just thin it out with a splash of water!
Notes
*Use less broth for a thicker gravy, more for a thinner one.**Mushroom Seasoning - I've recently tested this with both Miso Paste and Nutritional Yeast instead of Mushroom Seasoning, and the Miso Paste version was good, but tasted a bit too much like Miso Paste. Nutritional Yeast was nuttier and earthier than I remember. So some kind of Mushroom Seasoning is ideal!Browning Sauce - Kitchen Bouquet and Gravy Master are my choices for this. It's mostly for color but does add some flavor. If you can't get it, don't worry about it, your gravy might just be a bit lighter in color.Other Additions - You can always add other umami packed ingredients into this. Soy sauce, vegan steak sauce, vegan worcestershire would all work great, so get creative and have fun with it!
