🛒 Ingredients (Serves 4)

4 large onions (sweet or yellow)
2 tbsp butter (plus extra for greasing)
¾ cup heavy cream
1 cup grated Asiago cheese
¼ cup grated Parmesan cheese (optional)
2 cloves garlic, minced (or 1 tsp garlic powder)
½ tsp salt (adjust to taste)
¼ tsp black pepper
½ tsp dried thyme (or 1 tsp fresh thyme)
Optional: pinch of paprika or chili flakes

👩‍🍳 Instructions

Start by preheating your oven to 375°F (190°C) and lightly greasing a baking dish with butter. Peel the onions and slice off the tops and bottoms, then cut them in half. Place the onion halves cut-side up in the prepared baking dish.

In a saucepan over medium heat, melt the butter and sauté the minced garlic for about 1 minute until fragrant. Add the heavy cream, salt, black pepper, and thyme. Stir gently and allow the mixture to warm up, but do not let it boil.

Next, sprinkle half of the grated Asiago cheese over the onions. Pour the warm cream mixture evenly over them, making sure each onion is well coated. Then top with the remaining Asiago and the Parmesan cheese, if using. For a little extra flavor and color, you can add a pinch of paprika or chili flakes on top.

🍽️ Serving Suggestions

Let the dish cool slightly before serving. These cheesy baked onions make a fantastic side dish for roasted meats, grilled chicken, or even as part of a vegetarian meal. The creamy sauce and caramelized edges make every bite rich and flavorful.
