How to Make Oven-Braised White Onions
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This temperature will ensure even cooking and caramelization of those lovely onions.
Step 2: Prepare Your Baking Dish
Grab a sturdy baking dish and drizzle it with olive oil. This will prevent sticking and add flavor to our dish. Now is also a great time to slice your white onions into thick rounds—aim for about half an inch thick.
Step 3: Arrange the Onions
Place the onion slices in a single layer in your baking dish. Don’t worry about being too precise; they’re going to become friends in there!
Step 4: Season Generously
Melt some butter and drizzle it over the onions. Sprinkle salt and freshly cracked pepper on top—be generous! Remember, seasoning is key.
Step 5: Cover and Bake
Cover your baking dish tightly with aluminum foil. This will trap steam and ensure your onions become soft and tender during baking. Pop it in the oven for about 45 minutes.
Step 6: Uncover and Finish
After 45 minutes, carefully remove the foil (watch out for steam—it’s sneaky!). Let them bake uncovered for an additional 15 minutes until they turn golden brown and slightly caramelized.
Transfer to plates and drizzle with any remaining buttery goodness for the perfect finishing touch!
And voilà! You have created an irresistible side dish that’s sure to steal the show at dinner time or maybe even earn you some culinary bragging rights among friends. Enjoy those Oven-Braised White Onions—they’re more than just onions; they’re pure culinary magic!
