Ingredients

• 3 large yellow onions, thinly sliced
• 3 tablespoons olive oil or vegan butter
• 2 cloves garlic, minced
• 2 tablespoons all-purpose flour
• 2 cups vegetable stock
• 1 tablespoon soy sauce or tamari (for gluten-free)
• 1 teaspoon fresh thyme (or ½ teaspoon dried thyme)
• 1 teaspoon balsamic vinegar
• Salt and freshly ground black pepper, to taste
• Optional: 1 teaspoon smoked paprika for a smoky kick

Equipment

• Large sauté pan or skillet
• Wooden spoon or spatula
• Whisk
• Sharp knife and cutting board
• Measuring cups and spoons
• Serving bowl or gravy boat

Instructions

1. Prepare the onions: Peel and thinly slice your onions. The thinner the slices, the faster they caramelize evenly.
2. Caramelize the onions: Heat the olive oil or vegan butter in a large sauté pan over medium-low heat. Add the sliced onions and a pinch of salt to draw out moisture. Stir occasionally for about 20-25 minutes until the onions turn a deep golden brown and soften into a jam-like consistency. Patience here is key for maximum flavor!
3. Add garlic and herbs: Stir in the minced garlic and thyme, cooking for another 1-2 minutes until fragrant.
4. Create the roux: Sprinkle the flour over the onions and stir constantly for 2 minutes to cook the raw flour taste out. This will help thicken your gravy.
5. Deglaze and simmer: Slowly pour in the vegetable stock while whisking continuously to avoid lumps. Add soy sauce and balsamic vinegar. Bring the mixture to a gentle simmer and cook for 5-7 minutes, stirring frequently until the gravy thickens to your desired consistency.
6. Season and finish: Taste and adjust with salt, pepper, and optional smoked paprika. If the gravy is too thick, add a splash more stock or water.
7. Serve warm: Transfer to a gravy boat or bowl and serve immediately, or keep warm until ready.

Tips & Variations

“For an even richer flavor, try adding a splash of red wine or a teaspoon of mustard during the simmering stage.”

• Make it gluten-free: Use a gluten-free flour blend or cornstarch slurry instead of all-purpose flour.
• For creaminess: Stir in a splash of coconut milk or plant-based cream at the end for a silky texture.
• Add mushrooms: Sauté chopped mushrooms with the onions for a deeper umami taste.
• Herb swap: Experiment with rosemary or sage instead of thyme for a different flavor profile.
• Make ahead: This gravy keeps well in the fridge for up to 3 days and reheats beautifully.
