How to Make Asiago Roasted Onions

Ready to dive into the delicious world of Asiago Roasted Onions? With each step, your kitchen will fill with fantastic aromas. Let’s break it down into simple, manageable tasks that anyone can follow.

Preparing the Onions

First, let’s get those onions ready. Start by peeling your yellow onions. Next, slice them into 1/4 inch to 1/2 inch thick pieces. I find that thicker slices give a meaty texture while staying sweet. Aim for uniformity so they cook evenly!

Once sliced, arrange the onions in a single layer in a greased baking dish. I recommend using a little non-stick spray or olive oil to avoid the dreaded sticking. Now, drizzle a generous amount of olive oil over the onions. Use your hands to toss everything around! This is where the magic begins as they coat and shine!

Roasting the Onions

Preheat your oven to a sizzling 450°F (230°C). This temperature is key for achieving that delightful caramelization.

Sprinkle the chopped thyme over your onions— a tiny herb that’ll work wonders. Then, season them with salt and pepper according to your taste. I typically use a good pinch because, trust me, this makes a world of difference!

Now it’s time to roast! Pop that baking dish in the oven and let them bake for about 20 minutes. You’ll know they’re ready once they start to soften and those edges turn golden brown. Just a tip: keep an eye on them to avoid burning!

Making the Creamy Sauce

While your onions are roasting, grab a small saucepan and heat the heavy cream over medium heat. Stir it gently until you see little bubbles form— this means it’s simmering. Then comes the fun part!

Add in the Dijon mustard and half of that glorious grated Asiago cheese. Stir it together until the cheese melts completely into a smooth, creamy sauce. Isn’t that a sight? Just imagine pouring this velvety sauce over those roasted onions.

Combining and Baking

After the onions have roasted to perfection, bring them out of the oven. Now carefully pour the creamy sauce over those beautiful caramelized onions, letting it drizzle into every nook and cranny.

Don’t forget to sprinkle the remaining Asiago cheese on top! It’s the finishing touch that’ll create that perfect cheesy crust.

Cover it all with foil, and pop it back in the oven for another 20 minutes. During this time, everything will meld beautifully, and you’ll be rewarded with tender onions, bubbling cheese, and all-around deliciousness. Just imagine serving this at your next family dinner!

Tips for Success

Don’t rush the roasting process—let the onions develop that rich caramelization.
For extra flavor, add minced garlic when making the creamy sauce.
Feel free to use a mix of cheeses. Parmigiano-Reggiano is a great substitute!

Experiment with herbs like rosemary or oregano for a unique twist.
Serve immediately for the best taste and texture.

Equipment Needed

Baking Dish: A medium-sized dish will work well; a cast-iron skillet offers a rustic touch too.
Small Saucepan: Any saucepan for heating the cream will do; just ensure it’s non-stick.

Knife and Cutting Board: Essential for slicing those onions safely.
Measuring Cups: Handy for the cream and cheese, but eyeballing it works too!
