Savory Umami Peanut Butter Toast with Caramelized Onions

1.Prepare the Onions: Heat the butter or neutral oil in a small skillet over medium-low heat. Add the thinly sliced onions and a tiny pinch of salt. Sauté slowly for 10-15 minutes, stirring occasionally, until deeply golden brown and caramelized. Set aside.

2.Prepare the Peanut Butter Spread: In a small bowl, combine the peanut butter, soy sauce, and vanilla extract (if using). Mix thoroughly until the soy sauce is fully incorporated, creating a savory, umami spread. Add a pinch of black pepper.

3.Toast the Bread: Preheat your air fryer to 180°C (350°F). Place the bread slices directly in the basket. Air fry for 3-5 minutes, or until golden brown and crisp. Alternatively, toast the bread in a toaster or pan-fry with 1 teaspoon of oil until golden.

4.Assemble the Toast: Once the bread is toasted, immediately spread the savory peanut butter mixture evenly over both slices.

5.Top and Serve: Distribute the caramelized onions evenly over the peanut butter layer. If desired, lightly drizzle the vanilla syrup over the top for a subtle sweet counterpoint.

6.Serve immediately while the toast is warm.
