How to Make onion Parmesan Toasts
Follow these simple steps to prepare this delicious dish:
Step 1: Prepare the Onions
Start by slicing two medium-sized onions thinly. Heat a tablespoon of olive oil in a large skillet over medium heat. Add the onions along with a pinch of salt, stirring occasionally until they caramelize—about 20-25 minutes should do the trick.
Step 2: Preheat Your Oven
While your onions are working their magic, preheat your oven to 350°F (175°C). This step is crucial as it ensures everything bakes evenly and becomes delightfully crispy.
Step 3: Slice the Baguette
Take your fresh baguette and slice it into half-inch thick pieces. Arrange these slices on a baking sheet lined with parchment paper for easy cleanup later.
Step 4: Assemble the Toasts
Drizzle each slice with olive oil and use a spoon to spread the caramelized onions evenly on top. Follow up by generously sprinkling freshly grated Parmesan over each toast and adding some fresh thyme leaves.
Step 5: Bake Until Golden
Pop your baking sheet into the oven and bake for about 10-12 minutes or until the tops are bubbly and golden brown. Keep an eye on them—nobody likes burnt toast!
Step 6: Serve Warm
Once baked to perfection, remove them from the oven and let them cool slightly before serving. These onion Parmesan Toasts are best enjoyed warm, so gather your friends around and dig in!
Transfer to plates and drizzle with sauce for the perfect finishing touch!
