Ingredients for beef belly slices
Fatty beef belly, bold spices, and a crispy crust—this is the holy trinity for restaurant-quality bites.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Belly (thick-cut) 🥩 | 2 ½ lb | Thick-cut, fatty side up |
| Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Black Peppercorns 🌶️ | 1 ½ tbsp | Freshly cracked, coarse |
| Cornstarch 🌾 | ½ cup | For crispy coating |
| All-Purpose Flour 🌾 | ¼ cup | Fine sifted |
| Baking Powder 🌾 | 1 tsp | For extra crispiness |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | For depth of flavor |
| Olive Oil 🫒 | ¼ cup | High smoke point |
| Yellow Onion 🧅 | 1 whole | Thinly sliced, for garnish |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, for aroma |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, chopped |
| Butter (unsalted) 🧈 | ¼ cup | Cold, cubed |
The beef belly is the star—look for thick-cut pieces with good marbling at Whole Foods or your local butcher. If buying pre-sliced, Costco has the best quality for this recipe. The fat content is what makes these slices melt-in-your-mouth, so don't skimp. For the dry brine, use Diamond Crystal kosher salt—it dissolves better than table salt. I always buy extra because you'll want it for everything after this. The spices? Freshly cracked black pepper and ground powders make all the difference—pre-ground loses flavor fast.
No cornstarch? Arrowroot powder works 1:1, but the texture won't be quite as crispy. Skip the baking powder if you're in a pinch, but trust me on keeping it—it's what gives those slices that satisfying crunch. For the herbs, fresh is ideal, but dried at half the amount gets you close. The butter should be cold when you cube it—soft butter means less crispiness. And if you're feeling fancy, swap the olive oil for avocado oil—it's got a higher smoke point for frying.
Store the raw beef belly in the coldest part of your fridge, wrapped tightly in parchment paper. Once cooked, these slices reheat beautifully—just 10 minutes at 350°F wrapped in foil. The rendered fat keeps for 1 month in the fridge, so portion it out for easy use. Freeze extras in ice cube trays for perfect-sized portions later. These slices are even better the next day—let them rest overnight if you can, and the flavors will meld perfectly.

Step-by-step instructions for crispy-crusted beef belly slices
Here's how to transform tough beef belly into melt-in-your-mouth slices with a shatteringly crisp exterior.
Cure and Rest the Beef Belly
Pat the 2.5 lb beef belly dry with paper towels—this is crucial for crispiness. In a bowl, combine the 2 tbsp kosher salt and 1.5 tbsp freshly cracked black peppercorns, then rub this mixture all over the beef belly, pressing it into every crevice. Place the belly fat-side up on a plate and refrigerate uncovered for 24 hours—this drying and curing process is what creates that legendary crispy crust.
After 24 hours, remove the beef belly from the fridge and let it sit at room temperature for 30 minutes before cooking. This step ensures even cooking and prevents the meat from steaming in its own juices. The belly should feel firm to the touch, with a well-developed crust of salt crystals on the surface.
Create the Crispy Coating
In a large bowl, whisk together the 0.5 cup cornstarch, 0.25 cup all-purpose flour, 1 tsp baking powder, 1 tsp garlic powder, and 1 tsp onion powder. This dry blend is the secret to that perfect crunch. Sift the mixture to remove any lumps, then add the 0.25 cup olive oil and mix with your fingers until it forms a coarse, sandy texture—like wet sand that holds together when squeezed.
Spread the coating mixture on a plate and carefully coat the beef belly in an even layer, pressing gently to help it adhere. The coating should be thick enough to create a substantial crust but not so thick that it prevents crisping. Let the coated belly rest for 10 minutes at room temperature—this helps the coating stick better during cooking.
Render the Fat and Sear the Belly
Heat a heavy skillet or cast-iron pan over medium-low heat and add the 0.25 cup cold cubed butter. Let it melt completely, then add the beef belly fat-side down. Cook for 10 minutes without moving it—this gives the fat time to render slowly and create a golden crust. The butter will foam and bubble as it melts, which is normal and actually helps create that crispy texture.
After 10 minutes, carefully flip the beef belly and cook for another 10 minutes on the second side. You'll see the coating turn deep golden brown and the fat begin to render out into the pan. This rendered fat is pure flavor—don't pour it off! It's what makes these slices so rich and delicious. The internal temperature should reach 160°F—this is the perfect starting point for the final cooking stage.
Finish in the Oven for Perfect Doneness
Preheat your oven to 350°F. Transfer the beef belly to a baking sheet lined with parchment paper, fat-side up. Pour any rendered fat from the pan over the top of the belly—this bastes the meat and adds extra flavor. Bake for 1 hour 30 minutes until the internal temperature reaches 195°F and the coating is deep golden brown and crispy all over.
Here's the thing—this long cook time is what transforms tough beef belly into tender, pull-apart slices. The slow oven finish ensures the meat becomes fork-tender while maintaining that crispy exterior. If the coating starts to darken too quickly, tent the pan with foil to prevent burning while still allowing the meat to cook through.
Rest and Slice for Maximum Juiciness
Remove the beef belly from the oven and let it rest for 30 minutes before slicing. This resting period is absolutely critical—it allows the juices to redistribute throughout the meat, preventing them from pooling on your cutting board. Tent the belly loosely with foil to keep it warm during this time.
After resting, slice the beef belly against the grain into ¼-inch thick slices. The slices should be tender enough to pull apart with a gentle tug but still hold their shape. Arrange the slices on a serving platter and garnish with the thinly sliced yellow onion, chopped fresh rosemary, and chopped fresh thyme. Serve immediately while still warm and crispy—these slices are best enjoyed right away when the crust is at its peak crunch.
Pro Tips For Making Beef Belly Slices
- Trim the Fat First: Beef belly’s fat is flavor, but thick layers make even cooking a nightmare. Use kitchen shears to snip the fat into ¼-inch strips—this keeps slices crispy without turning them greasy. (I learned this the hard way after frying a batch that oozed like a lava lamp.)
- Salt Like a Pro: Don’t just sprinkle salt on day-of—do it two days ahead. Rub the belly generously with kosher salt (about 1 tablespoon per pound) and refrigerate uncovered. The salt cures the meat, tightens the fibers, and guarantees that crust. (Yes, even if you’re impatient like me.)
- Double-Dredge for Crunch: Skip the lazy single dip in flour. After patting the beef dry, coat it in flour, shake off excess, then dip again in a 50/50 cornstarch-flour mix. The extra layer locks in moisture while creating a shatteringly crisp exterior. (Your future self will thank you.)
- Fry in Batches: Crowd the pan, and your beef belly turns soggy. Fry slices in a single layer over medium-high heat—no more than 3 at a time—until golden. If the oil smokes, lower the heat slightly. (I used to rush this and ended up with greasy, uneven results.)

Spicy Sriracha Aioli
For a bold kick, blend ½ cup mayonnaise, 1 tbsp sriracha, 1 tsp soy sauce, 1 tsp honey, and 1 tsp rice vinegar until smooth. Thin with 1 tsp water if needed.
The tangy, spicy contrast cuts through the richness of the beef belly beautifully. I like to serve this in a small bowl with extra sriracha on the side for those who want more heat. 🌶️
Red Wine Reduction
Create depth with a simple red wine reduction using ½ cup dry red wine, 1 tbsp beef broth, and 1 tsp balsamic vinegar. Simmer in a saucepan over medium heat until reduced by half (8-10 minutes).
Finish with 1 tsp cold butter for a glossy finish. This sauce adds elegant acidity that balances the richness of the beef belly slices. Perfect for a more sophisticated presentation. 🍷
Honey Mustard Glaze
Whisk together 2 tbsp Dijon mustard, 2 tbsp honey, 1 tbsp apple cider vinegar, and 1 tsp olive oil until smooth. Drizzle lightly over the beef belly slices just before serving.
The sweet-tangy glaze adds a bright contrast that makes each bite even more delicious. This is my go-to for a quick but impressive sauce option. 🍯

For a fresh, herbaceous option, blend 1 cup chopped parsley, ¼ cup chopped cilantro, 3 minced garlic cloves, 2 tbsp red wine vinegar, ¼ cup olive oil, ½ tsp red pepper flakes, and 1 tsp salt in a food processor.
Pulse until combined but still slightly chunky. This vibrant green sauce adds a bright, herby contrast that cleanses the palate between rich bites. 🌿
Rendered Fat Drizzle
Don't waste that precious rendered beef fat! Strain it through a fine-mesh sieve to remove any impurities, then drizzle it generously over the sliced beef belly. The fat itself is a luxurious sauce that enhances the natural beefy flavor.
For extra richness, warm the fat slightly before drizzling. This is the simplest yet most effective sauce option for beef belly slices. 🥩

Frequently asked questions
Why do I need to salt the beef belly 24 hours before cooking?
The dry brine process is essential for creating that signature crispy crust. The salt draws out moisture from the surface, which evaporates during the uncovered refrigeration, creating a concentrated salt crust. This crust acts as a barrier that prevents the meat from steaming in its own juices during cooking, resulting in that perfect crunch. Skipping this step means you'll miss out on the restaurant-quality texture these slices are known for!
Can I substitute cornstarch with something else for the crispy coating?
Yes, you can use arrowroot powder in a 1:1 ratio, though the texture won't be quite as crispy. For a gluten-free option, try rice flour mixed with 1 tsp baking powder per ¼ cup. The baking powder is key for that extra crunch—don't leave it out! The coating should still be thick enough to create a substantial crust, even with these substitutes.
How do I know when the beef belly is fully cooked?
Use a meat thermometer to check the internal temperature—it should reach 195°F for perfect doneness. The slices should be fork-tender and pull apart easily when sliced. If the coating starts to darken too quickly in the oven, tent it with foil to prevent burning while allowing the meat to cook through. The rendered fat should be golden and bubbly, indicating proper cooking.
Can I make this recipe ahead of time?
These slices are even better the next day. After cooking, let them cool completely, then store in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F for 10-15 minutes wrapped in foil to restore crispiness. The flavors meld beautifully overnight, making them ideal for meal prep or special occasions.
What's the best way to serve these beef belly slices?
These slices work beautifully as a standalone dish, but they're even more impressive with complementary sides. Try serving them with roasted potatoes, a crisp green salad, or steamed vegetables. The rendered fat makes a luxurious sauce—drizzle it over the slices or serve it on the side for dipping. For a complete meal, pair with one of the sauces from the dynamic content section, like the classic garlic butter or spicy sriracha aioli.
