Ingredients

For the Gravy:

• 6 tablespoons butter: This forms the base of the gravy, adding richness and depth.
• 2 large yellow onions, cut in half and sliced thin: Yellow onions are ideal for caramelizing, offering the right balance of sweetness and flavor.
• ⅛ teaspoon kosher salt: Enhances the flavor of the onions and helps with the caramelization process.
• 2 cups low-sodium beef broth: Provides a savory foundation for the gravy. You can also substitute vegetable broth for a vegetarian option.
• 1 teaspoon Worcestershire sauce: Adds a tangy, umami flavor that deepens the overall taste of the gravy.
• 1 teaspoon Dijon mustard: Gives a slight kick and sharpness that balances the sweetness of the caramelized onions.
• 1 ½ tablespoons cornstarch: Used to thicken the gravy to your desired consistency.
• Kosher salt and black pepper to taste: Season the gravy according to your preference.
• 1 tablespoon chopped fresh thyme (or 1 teaspoon dried thyme): Adds a fresh, aromatic flavor that complements the savory notes of the gravy.

Instructions

Step 1: Prepare the Onions

Start by melting the butter in a large skillet over medium heat. Once the butter is fully melted and begins to bubble, add the thinly sliced onions and kosher salt. Stir the onions to coat them evenly with the butter and salt. Continue to cook the onions, stirring every few minutes.

Tip:

Caramelizing onions requires patience. It can take up to 45 minutes to achieve the perfect golden-brown color. If the onions start to brown too quickly, reduce the heat slightly. If they begin to stick to the bottom of the pan, deglaze them with a tablespoon of red wine vinegar, wine, or balsamic vinegar. This will help to lift the flavorful bits stuck to the pan and incorporate them into the onions.

Step 2: Caramelize the Onions

Allow the onions to cook slowly until they reach a rich, caramelized state. The onions should be a deep golden-brown color and have a sweet, savory flavor. This step is crucial, as the caramelized onions will be the primary flavor component of your gravy.

Step 3: Create the Gravy Base

Once the onions are fully caramelized, stir in 1¾ cups of the beef broth, Worcestershire sauce, and Dijon mustard. Mix well to combine all the ingredients and bring the mixture to a low boil.

Step 4: Thicken the Gravy

In a small bowl, whisk together the remaining ¼ cup of beef broth and the cornstarch until smooth. Slowly add the cornstarch mixture to the skillet, whisking continuously to prevent lumps from forming. Continue to cook the gravy until it thickens to your desired consistency. This should take just a few minutes.

Step 5: Season and Serve

Reduce the heat to low and season the gravy with salt and black pepper to taste. Finally, whisk in the chopped fresh thyme. For the best flavor, serve the gravy promptly over your favorite dish.

Tip:

If you’re not serving the gravy immediately, you can keep it warm over low heat. Stir occasionally to maintain a smooth consistency.

Tips for the Perfect Caramelized Onion Gravy

• Onion Caramelization: The key to a rich onion gravy is properly caramelized onions. Don’t rush this process, as it’s where most of the flavor develops. Thinly sliced onions caramelize more evenly and quickly.
• Adjusting Thickness: If your gravy is too thick, you can thin it out by adding a bit more beef broth. Conversely, if it’s too thin, simmer it a little longer to reduce and thicken the sauce.
• Herb Variations: Thyme adds a lovely earthiness to the gravy, but feel free to experiment with other herbs like sage, parsley, rosemary, or chives for different flavor profiles.
• Vegetarian Option: Simply substitute the beef broth with vegetable broth to make a vegetarian version of this gravy. The flavor will be slightly different but still delicious.
