Ingredients

• 4 large sweet onions (Vidalia or Walla Walla are ideal)

• 2 tbsp all-purpose flour

• 1 ½ cups heavy cream (or half-and-half for lighter version)

• ½ tsp salt (adjust to taste)

• ¼ tsp black pepper

• ¼ tsp ground nutmeg (optional but adds warmth)

• 1 cup grated Asiago cheese (divided, about ¾ cup for sauce, ¼ cup for topping)

• ¼ cup grated Parmesan cheese

• 2 tbsp fresh parsley, chopped (optional garnish)

Instructions

1. Prep the Onions

   • Preheat oven to 375°F (190°C).

   • Peel onions and slice them into ½-inch thick rings.

   • Place onion slices in boiling water for 5 minutes to soften slightly, then drain well.

2. Make the Creamy Asiago Sauce

   • In a medium saucepan, melt butter over medium heat.

   • Stir in flour and cook for 1 minute to make a roux.

   • Gradually whisk in the heavy cream until smooth.

   • Add salt, pepper, and nutmeg.

   • Stir in ¾ cup Asiago cheese until melted and creamy.

3. Assemble the Dish

   • Arrange onion slices in a buttered baking dish.

   • Pour the Asiago cream sauce evenly over the onions.

   • Sprinkle with remaining ¼ cup Asiago cheese and Parmesan.

4. Bake

   • Bake uncovered for 30–35 minutes until bubbly and golden on top.

5. Serve

   • Garnish with parsley if desired.

   • Serve hot as a side to roasted meats, chicken, or holiday meals.

💡 Tips & Variations:

• For a deeper flavor, add 2 cloves of roasted garlic to the sauce.

• Swap half the Asiago with Gruyère for a nuttier, meltier texture.

• If you want extra crunch, sprinkle a handful of buttery breadcrumbs over the top before baking.
