Instructions

Preheat and prepare baking dish: Preheat your oven to 375°F (190°C). Lightly grease a baking dish that fits the onion halves snugly to prevent sticking.
Parboil the onions: Place the halved onions in a large pot of salted boiling water and simmer for 10 minutes until slightly softened. Drain the onions well and set them aside to cool slightly so they are easier to handle.
Make the creamy Asiago sauce: In a skillet over medium heat, melt the butter together with the olive oil. Add the minced garlic and sauté for about 1 minute until fragrant but not browned. Stir in the heavy cream, grated Asiago cheese, dried thyme, and season with salt and black pepper. Allow the mixture to simmer gently for 2 to 3 minutes until it thickens slightly to a creamy consistency.
Assemble the dish: Arrange the parboiled onion halves cut side up in the prepared baking dish. Pour the creamy Asiago sauce evenly over the onions, making sure each piece is well coated. Sprinkle a bit of extra grated Asiago cheese on top for a golden crust.
Bake covered: Cover the baking dish tightly with foil to trap steam and bake in the preheated oven for 25 minutes. This allows the onions to cook through and absorb the creamy sauce flavors.
Finish baking uncovered: Remove the foil and bake for an additional 15 to 20 minutes until the onions are tender all the way through and the cheese topping is bubbly and golden brown.
Garnish and serve: Remove the baked onions from the oven, garnish with freshly chopped parsley, and serve warm. This dish pairs wonderfully with roasted meats or as a flavorful holiday side.

Notes

This dish pairs beautifully with roasted meats or as a standout holiday side.
For added depth, try using a mix of Asiago and Parmesan cheese in the sauce.
Ensure onions are parboiled but not fully cooked before baking to achieve the perfect tender texture.
If you prefer a thicker sauce, simmer the cream mixture a little longer before assembling the dish.
