Preparation Phase & Tools to Use

To start your culinary journey with Asiago Creamy Baked Onions, ensure your kitchen is well-prepared. Begin by preheating your oven to 450°F (230°C). A good baking dish is crucial for this recipe, so choose a medium-sized ceramic or glass dish that can distribute heat evenly. Greasing your baking dish lightly with olive oil will help prevent sticking, ensuring the onions lift off easily once baked.

Gather all your ingredients within reach. You’ll need a sharp knife to slice the onions into uniform ¼-inch rounds, which aids in consistent cooking. Also, prepare a small saucepan for the sauce; having one with a non-stick base can help avoid the cream curdling as it cooks. Lastly, a whisk will be handy when combining the Asiago and Dijon into the simmering cream, ensuring a smooth, creamy sauce.

Ingredients

4 large yellow onions, sliced into ¼-inch rounds
Olive oil, for drizzling
½ tsp fresh thyme, chopped
Salt & pepper, to taste
1 cup heavy cream
2 tsp Dijon mustard
½ cup Asiago cheese, grated

Instructions

Step 1: Roast the Onions

Begin by preheating your oven to 450°F (230°C). Grease a baking dish and carefully lay the onion slices flat in a single layer. This arrangement allows the onions to cook evenly. Drizzle them generously with olive oil, ensuring each slice is well coated. Sprinkle fresh thyme, salt, and pepper over the top, then roast in the oven for 20 minutes. The goal is to soften the onions and allow them to caramelize lightly on the edges, which brings out their inherent sweetness.

Step 2: Prepare the Cheesy Cream Sauce

While the onions are roasting, focus on the sauce. In a medium saucepan, gently heat the cream over medium heat until it begins to simmer gently. Keep a watchful eye to avoid boiling, which can lead to separation. Whisk in the Dijon mustard, which adds a slight tang to balance the richness of the cream. Next, stir in half of the grated Asiago cheese. Continue stirring until the cheese is fully melted and integrated into the sauce, creating a luscious, velvety cream.

Step 3: Combine and Bake

Once the onions are roasted, pour the creamy sauce evenly over them in the baking dish. Sprinkle the remaining Asiago cheese atop the sauce-coated onions, ensuring a cheesy crust will form. Cover the dish with foil to prevent over-browning and bake for another 20 minutes. The goal is to see the cheese melted and the sauce bubbling, ensuring the onions are tender inside.

Variations

Protein: Add cooked and crumbled bacon or pancetta for a smoky, savory twist.
Vegetables: Incorporate sliced mushrooms or spinach for added texture and nutrients.
Spices: Experiment with a pinch of nutmeg or a dash of smoked paprika in the cream sauce for an extra layer of flavor.

Cooking Notes

When choosing onions, select fresh and firm large yellow onions for the best flavor and texture.
For a milder taste, use sweet onions like Vidalia instead of yellow onions.
The sauce can be prepared ahead of time and refrigerated. Reheat gently before pouring over the onions.
Adjust the seasoning of your cream sauce after tasting, as cheese might add a salty flavor that can surprise.

Serving Suggestions

Pair with a juicy roast chicken or a tenderloin steak for a delightful dinner.
Serve alongside a fresh garden salad to balance the creaminess of the dish with refreshing greens.

Tips

Ensure onions are evenly sliced for consistent cooking and the best texture.
Use freshly grated Asiago for the fullest cheesy flavor instead of pre-grated cheese, which often lacks intensity.

Yes, you can prepare and assemble the dish a day in advance. Store it covered in the refrigerator and bake before serving.

If Asiago cheese is unavailable, Romano cheese can provide a similar tangy and savory quality.
