Ingredients
  

Main Ingredients
  • 4 large large onions Sweet onions work wonderfully!
  • 1 cup heavy cream
  • 1 cup shredded Asiago cheese Feel free to substitute with Parmesan or Gruyere.
  • 1 tablespoon olive oil
  • 2 teaspoons fresh thyme Or 1 teaspoon dried thyme.
  • Salt and pepper to taste
  • Optional: breadcrumbs for topping If you're feeling fancy!

Method
 

Preparation and Baking
  1. Preheat the oven to 375°F (190°C).
  2. Slice the tops off the onions and remove the skin. Scoop out some of the insides to create mini onion bowls.
  3. In a mixing bowl, combine the heavy cream, ¾ of the Asiago cheese, thyme, salt, and pepper. Mix in some of the scooped-out onion if desired.
  4. Drizzle each onion with olive oil, then carefully spoon the creamy filling into each onion.
  5. Sprinkle the remaining Asiago cheese on top, and add breadcrumbs if using.
  6. Place the stuffed onions in a baking dish with a little water (about half an inch) and cover with foil. Bake for 45 minutes, then remove the foil and bake for an additional 15 minutes until golden and bubbly.
  7. Let cool slightly before serving.

Notes

Chilling onions before cutting can help reduce tears. You can substitute heavy cream with half-and-half or plant-based milk for a lighter version.
