Why You’ll Fall in Love with This Recipe
While onions are often relegated to the background of most recipes, here they are the undisputed star. This dish works because it perfectly balances the natural sweetness of caramelized onions with the sharp, salty punch of aged cheese and the silkiness of heavy cream.
- Sweet and Tender: Slow-roasting removes the onion’s bite, leaving behind a mellow, buttery texture.
- Rich Cream Sauce: A touch of Dijon mustard cuts through the heavy cream, adding a subtle tang.
- Asiago Perfection: This specific cheese provides a unique depth of flavor that is far more interesting than standard mozzarella.

Frequently Asked Questions
Can I make this dish ahead of time?
Yes! You can assemble the dish up to the point of the second bake. Simply cover the baking dish tightly with foil and refrigerate for up to 24 hours. When you’re ready to eat, bake it as directed, adding about 5–10 minutes to the covered baking time to account for the cold dish.
What can I use instead of Asiago cheese?
While Asiago is preferred for its unique nutty and sharp profile, you can easily substitute it with Parmesan, Gruyère, or a sharp White Cheddar. Each will offer a slightly different flavor profile, but all pair beautifully with the sweetness of the onions.
Which onions work best for baking?
Yellow onions are the best choice for this recipe because they have a high sugar content that caramelizes beautifully during the roasting process. You can also use Vidalia or Sweet onions for an even milder, sweeter result, though they may release slightly more moisture.
