Preheat and Prep: Preheat your oven to 375°F (190°C). Line a large rimmed baking sheet with parchment paper to catch the rendering fat and ensure easy cleanup.
Arrange: Lay the pork belly strips flat on the prepared baking sheet. Ensure the strips are in a single layer and not overlapping, which allows the heat to circulate and crisp the edges evenly.
Season (Optional): If desired, sprinkle both sides of the strips lightly with salt and black pepper.
Bake: Place the baking sheet on the center rack of the oven. Bake at 375°F for 50 minutes.
Check for Doneness: At the 50-minute mark, the fat should look translucent and bubbly, and the meaty portions should be a deep golden brown. For extra crispy edges, you can leave them in for an additional 5–10 minutes, watching closely to ensure they don't burn.
Drain: Carefully remove the pan from the oven. Using tongs, transfer the strips to a plate lined with paper towels (or a wire cooling rack) to drain the excess liquid fat for 1–2 minutes.
Serve: Serve warm while the edges are at their peak crunch.
Storage: Store leftovers in an airtight container in the refrigerator for up to 5 days.
Pro Tip: Save the liquid fat (lard) from the baking sheet! Filter it into a glass jar and keep it in the fridge for searing steaks or frying eggs later.
