Description
Creamy Baked Onions with Asiago Cheese: Rich and comforting dish featuring sweet caramelized onions smothered in creamy Asiago cheese sauce.
Ingredients
Scale
- 4 large sweet onions (about 2.5 lbs/1.1 kg)
- 3 tablespoons unsalted butter (42g)
- 2 tablespoons all-purpose flour (16g)
- 1 cup heavy cream (240ml)
- ½ cup whole milk (120ml)
- 1½ cups shredded Asiago cheese, divided (about 6 oz/170g)
- 1 tablespoon fresh thyme leaves (or 1 teaspoon dried)
- ¼ teaspoon freshly grated nutmeg
- Salt and freshly ground black pepper to taste
- 2 tablespoons breadcrumbs (optional, for extra crispiness)
Instructions
- Step 1: Prepare the Onions Preheat your oven to 375°F (190°C). Peel the onions and cut them into ½-inch thick slices, then separate into rings. Butter a 2-quart baking dish and arrange the onion rings evenly inside. Season generously with salt and freshly ground black pepper. This may seem like a lot of onions, but they’ll cook down significantly, releasing their sweet flavor into the creamy sauce of your Creamy Baked Onions with Asiago Cheese.
- Step 2: Create the Cream Sauce In a medium saucepan over medium heat, melt the butter. Once it’s bubbling, add the flour and whisk constantly for 2 minutes until you’ve formed a smooth paste. Gradually pour in the heavy cream and milk, whisking continuously to prevent lumps. Keep whisking until the mixture thickens enough to coat the back of a spoon, about 3-4 minutes. Remove from heat and stir in 1 cup of the Asiago cheese, thyme, and nutmeg until the cheese melts completely. Taste and adjust seasoning with salt and pepper.
- Step 3: Assemble and Bake Pour the cheese sauce evenly over the prepared onions, ensuring all pieces are coated. Cover the baking dish with aluminum foil and bake for 30 minutes. This initial covered baking helps steam the onions until tender while they absorb the flavors of the sauce. After 30 minutes, remove the foil, sprinkle the remaining ½ cup of Asiago cheese on top, and bake uncovered for an additional 15-20 minutes until the top is golden brown and bubbly.
- Step 4: Finish and Serve Let your Creamy Baked Onions with Asiago Cheese rest for 5-10 minutes before serving. This crucial resting period allows the sauce to thicken slightly and the flavors to settle. If desired, garnish with additional fresh thyme leaves for a pop of color and fresh flavor. Serve warm alongside your favorite protein or as a vegetarian main with a simple green salad for contrast.
