  Instructions

  1. Roast the Onions

  • Preheat oven to 450°F (230°C). Lightly grease a  baking dish with  olive oil.

  • Arrange onion slices in a single layer. Drizzle with olive oil, then sprinkle with thyme, salt, and pepper.

  • Roast for 20 minutes, or until the onions begin to soften and caramelize at the edges.

  2. Make the Cream Sauce

  • In a small saucepan, warm the  heavy cream over medium heat until it just begins to simmer.

  • Whisk in the Dijon mustard and ¼ cup of Asiago cheese until melted and smooth.

  3. Assemble & Bake

  • Remove onions from the oven and pour the cream sauce evenly over them.

  • Sprinkle the remaining ¼ cup of Asiago cheese on top.

  • Cover with foil and bake for 20 more minutes, or until bubbly and golden.

  4. Serve & Enjoy

  • Let rest for 5 minutes before serving. Garnish with extra thyme if desired.

  • Pairs beautifully with roasted meats, grilled chicken, or crusty bread.

  Tip: For extra richness, broil for 1–2 minutes at the end for a crispy cheese topping!
