Step‑by‑Step Instructions for Creamy Baked Onions with Asiago Cheese
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature is essential for achieving the perfect bake that will allow the onions to caramelize while the Asiago cheese melts beautifully. As the oven heats, prepare your yellow onions by slicing them into ½ to ¾ inch thick rounds, setting the stage for a deliciously tender dish.
Step 2: Sear the Onions
In a large skillet over medium heat, add a drizzle of olive oil or a knob of butter to warm up. Once hot, add the sliced onions and sauté for 3-4 minutes on each side until they become lightly browned and fragrant. This step enhances the flavor profile in your Creamy Baked Onions with Asiago Cheese, creating a lovely caramelization that elevates the dish.
Step 3: Arrange the Onions
Carefully transfer the browned onion slices into a baking dish, arranging them in a single layer for even cooking. This allows the cream to envelop each slice perfectly. Make sure they fit snugly to ensure that every bite is filled with rich, oniony goodness.
Step 4: Add the Cream
Pour heavy cream around and slightly over the onion slices, ensuring they are well coated. The cream will create a savory sauce as it bubbles and thickens in the oven. This luscious base is essential for the creamy texture you desire in your Creamy Baked Onions with Asiago Cheese.
Step 5: Season and Cheese
Generously sprinkle grated Asiago cheese over each onion slice, covering them evenly for maximum flavor. Season with salt and freshly cracked black pepper to taste. The combination of creamy sauce, sweet onions, and cheesy goodness will make this dish irresistible.
Step 6: Bake to Perfection
Place the baking dish uncovered in the preheated oven and bake for 25-30 minutes. Keep an eye on it as the onions become tender and the cheese turns golden and bubbly. This visual cue indicates that your Creamy Baked Onions with Asiago Cheese is nearly ready to be savored!
Step 7: Garnish and Serve
Once baked, remove the dish from the oven and let it cool slightly. Garnish with fresh thyme or parsley for a pop of color and added freshness. Your Creamy Baked Onions with Asiago Cheese is now ready to be served warm, presenting the perfect blend of textures and flavors that everyone will love.
