How to make this vegan gravy recipe

This recipe for onion and mushroom vegan gravy gets its rich, savory flavor from the caramelized onions. This vegan brown gravy will come in handy on Thanksgiving, Christmas, and any other festive event.

How to caramelize onions

The most time consuming (yet crucial) part of making this recipe is caramelizing the onions. It takes around 30 minutes to bring out their natural sweetness.

My favorite onion for this gravy is yellow onion. It’s nice and mild with a naturally occurring sweetness you want for caramelized onions.

To start, cut onions in half from the middle. Now is when I break out my trusty mandoline slicer, which makes this process so much faster. Just place the onion cut-side down on the mandoline and slice with a careful, controlled motion. Use the hand guard that’s included as you’re reaching the last part of the onion. Trust me on this: I once had a nasty cut from a mandoline for using it hastily and not using the hand guard. Ouch!

The trick to caramelizing onions is to let them fry for a good 5-8 minutes in between stirring to get those browned bits on the base of your pot. Then, with each stir, scrape the bottom of the pan to get those browned bits mixed through. The key is that your onions are soft, nicely browned and not burnt. It’s so important to watch the onions closely as they brown so they won’t burn. Medium low heat, frequent stirring and lots of patience (or at least 20 minutes) is needed when caramelizing onions, but the payoff is worth it.

Once the onions start to caramelize, lower heat to medium low, stirring often, for around 10 minutes more. Add the cornstarch and combine well.

“Don’t crowd the mushrooms”

While the onions are caramelizing, add 2 tbsp olive oil to a small saucepan under medium heat. Add mushrooms and sauté, taking care not to crowd them, and keep them in a single layer.

Cook mushrooms for about 1 minute on one side, flip them, and cook for 2-3 more minutes. Add garlic and cook until fragrant, about 1 minute. When the mushrooms are nicely browned, remove from heat and set aside.

Next, once the onions are caramelized, add the vegetable broth, combining well. Simmer for about 5 minutes until it thickens.

Using a high speed blender or an immersion blender, blend the gravy until smooth and lump-free. Season with salt and pepper to taste. Stir in the mushrooms and serve in an adorable gravy boat such as this one.

Easy, right?
