I present pork belly as impossibly crisp, lacquered slices that shatter and melt in your mouth, their glossy, deeply caramelized finish compelling you to keep scrolling.

I am obsessed with oven baked pork belly slices. I love the crackle of rendered fat and the way the edges caramelize into something almost sinful.

The meat stays unbelievably tender while the exterior crisps, giving you bold texture in every bite. I crave that hit of smoky heat from smoked paprika paired with a whisper of honey that sharpens the sweet-salty tension.

It makes leftovers feel dangerous. And I find myself pretending I’m at some late-night stall, fork in hand, no small talk.

Pure, unapologetic pork joy. Impossible to stop.

Worth the mess. I would fight for a slice.

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 400°F (200°C). Line a rimmed baking sheet with foil and set a wire rack on top, this keeps the pork out of the drippings so it crisps better.

2. Pat the pork belly slices very dry with paper towels, you want no surface moisture. Sprinkle 1 tsp kosher salt and 3/4 to 1 tsp freshly ground black pepper over both sides.

3. In a bowl mix 1 tbsp olive or neutral oil, 1 tbsp light brown sugar, 1 tsp garlic powder, 1 tsp onion powder, 1 tsp smoked paprika, 1 tbsp low sodium soy sauce or tamari, 1 tbsp honey or maple syrup, 1 tsp rice or apple cider vinegar, 1/4 tsp red pepper flakes or cayenne if you want heat, and 1/2 tsp baking powder. Stir until the sugar mostly dissolves.

4. Toss the pork slices in that mixture, making sure each slice is well coated. Let them sit at room temp for 15 to 20 minutes to take on the flavors. If you have time you can chill them covered for 1 hour or overnight for deeper flavor.

5. Arrange the slices in a single layer on the rack, leave space between pieces so air circulates. Wipe any excess wet marinade off the bottom of the slices so they don’t steam.

6. Roast in the preheated oven for about 20 to 25 minutes, then flip each slice and roast another 10 to 15 minutes. Total time will be 30 to 40 minutes depending on thickness, you want deep golden brown edges and rendered fat.

7. If you want them extra crisp, move the oven to broil and broil for 1 to 3 minutes watching constantly so they do not burn. That quick blast will blister and caramelize the glaze.

8. Remove from oven, let the pork rest 5 minutes on the rack so it firms up. Taste and add a little extra kosher salt if needed.

9. Sprinkle chopped fresh parsley or sliced green onion over the top and serve warm. These are great with rice, in sandwiches, or just on their own with toothpicks.

Equipment Needed

1. Rimmed baking sheet (large)
2. Wire cooling rack that fits the sheet
3. Paper towels
4. Mixing bowl (medium)
5. Measuring spoons and measuring cups
6. Tongs or two forks for flipping
7. Small whisk or spoon for mixing the glaze
8. Oven-safe baking thermometer or instant-read thermometer (optional but helpful)

FAQ

Q: How long and at what temperature do I bake the pork belly slices? A: Bake at 400°F (200°C). Start with 25 to 35 minutes, flipping once halfway, until the edges are brown and the fattest parts are crisp. Thicker slices take longer, thinner ones less. If you want extra crisp, finish under the broiler for 1 to 3 minutes but watch it close, it burns fast.

Q: Do I need to remove the skin or score it? A: No need to remove skin unless you hate it. Scoring the skin lightly helps fat render and lets seasonings stick, but dont go too deep or you’ll cut the meat. If slices have no skin, they still crisp up nice because of the baking powder and high heat.

Q: What does the baking powder do, and can I skip it? A: Baking powder raises pH a bit and helps the surface dry, so you get better crisping. You can skip it, but the texture wont be as crisp, more chewy. Use only the small amount listed so the flavor stays normal.

Q: Can I swap honey or maple syrup and what about soy sauce? A: Yes, swaps are fine. Any sweetener like brown sugar or agave works. For soy sauce, tamari or coconut aminos are fine if you need gluten free. Just keep balance salty and sweet so it caramelizes without burning.

Q: How do I reheat leftovers so they stay crispy? A: Reheat in a hot oven at 375°F (190°C) on a rack for 8 to 12 minutes, or in a skillet over medium heat for a few minutes per side. Microwaving makes them soggy, dont do that unless you dont mind limp pork.

Q: How long will leftovers keep and can I freeze them? A: Store cooked slices in the fridge for up to 4 days in an airtight container. Yes you can freeze up to 2 months, wrap tightly or use freezer bags. Thaw in the fridge overnight and re-crisp in the oven before serving.

Oven Baked Pork Belly Slices Recipe Substitutions and Variations

Kosher salt: sea salt or table salt (use about 3/4 the amount if using table salt), or soy sauce for some extra umami if you want less dry salt.
Light brown sugar: dark brown sugar for a deeper molasses note, white sugar plus a tsp molasses, or honey/maple if you want liquid sweetener (reduce other liquids slightly).
Low sodium soy sauce or tamari: regular soy sauce, coconut aminos for a soy free option, or Worcestershire for a tangier, savory swap.
1/2 tsp baking powder (for crisping): a pinch of cornstarch can help crisping too, or omit and just pat skin super dry and roast hotter and longer if you prefer no leavening agent.

Pro Tips

1. Pat the slices bone dry with paper towels before anything else, seriously. If the surface is even a bit wet the skin wont crisp, and you’ll end up steaming them instead of getting that crunchy edge.

2. Dont skip the baking powder, but dont overdo it either. That little 1/2 tsp helps the skin puff and crisp by changing the surface pH, so it gets extra crunchy. Mix it well into the marinade so it coats evenly, and if you use more salt reduce salt in the rub a bit.

3. Give them space on the rack and wipe away pooled marinade from the undersides. Air circulation is everything for even rendering. If pieces touch they steam, not crisp. Rotate the pan once mid cook so hot spots in your oven dont burn one side.

4. Finish smart: rest on the rack 5 minutes so fat firms up, then taste and add flaky salt if needed. If you want extra blistered bits, broil for only 1 to 3 minutes while watching like a hawk, because it can go from perfect to burnt in a blink.
