  • 6 tablespoons butter
  • 2 large yellow onions, cut in half and sliced thin
  • ⅛ teaspoon kosher salt
  • 2 cups low sodium beef broth
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon Dijon mustard
  • 1 ½ tablespoons cornstarch
  • Kosher salt and black pepper to taste

Step 1: Prepare the Onions

  1. Melt Butter:
    • In a large skillet, melt the butter over medium heat.
  2. Cook Onions:
    • Add the sliced onions and ⅛ teaspoon of kosher salt to the skillet. Cook, stirring occasionally, for about 20-25 minutes, or until the onions are caramelized and golden brown.

Step 2: Add Broth and Seasonings

    • Pour in the low sodium beef broth, Worcestershire sauce, and Dijon mustard. Stir to combine.

    • In a small bowl, combine the cornstarch with 2 tablespoons of cold water, stirring until smooth.
  2. Thicken Gravy:
    • Slowly pour the cornstarch mixture into the simmering gravy, stirring constantly. Continue to cook until the gravy has thickened, about 2-3 minutes.

Step 4: Season and Serve

  1. Add Thyme:
    • Stir in the chopped fresh thyme (or dried thyme) and season with additional kosher salt and black pepper to taste.
  2. Serve:
    • Serve the onion gravy hot over your favorite dishes such as mashed potatoes, meatloaf, or roasted meats.

Cooking Notes and Tips

  • Caramelizing Onions: Be patient while caramelizing the onions. Cook them slowly over medium heat to develop their natural sweetness and deep flavor.
  • Broth Choice: For a richer flavor, you can use a combination of beef and chicken broth.
  • Consistency: If the gravy is too thick, add a bit more broth to reach your desired consistency. If it’s too thin, let it simmer longer to reduce and thicken.


Mushroom Onion Gravy

  • Add Mushrooms:
    • Add 1 cup of sliced mushrooms to the onions during the caramelization process for a delicious mushroom onion gravy.

Red Wine Onion Gravy

  • Add Red Wine:
    • Replace ½ cup of the beef broth with red wine for a rich and sophisticated flavor.
