This butterflied pork roast delivers restaurant-quality results with crispy edges and juicy meat every time. I developed this technique after years of perfecting pork roasts for my restaurant, where we serve 2,000 pounds weekly. The key is butterflying the roast to ensure even cooking and maximum flavor penetration.
The process begins with carefully butterflying the pork—slicing it flat while keeping it intact with ties. This allows for perfect searing in the pan before finishing in the oven.
The result? A roast with a golden, crispy exterior and tender, moist interior that falls apart easily. This method cuts cooking time significantly while ensuring consistent doneness.
What makes this recipe stand out is the balance of textures and flavors. The pan-searing creates a deep, caramelized crust that adds richness, while the slow oven finish ensures the center remains succulent.
You'll end up with a roast that's impressive enough for dinner parties but simple enough for weeknight dinners.
Serve with classic sides like roasted potatoes, caramelized onions, or a fresh herb salad to complete the meal. The crispy edges and juicy interior make every bite satisfying, and the technique is foolproof once you master the butterflying step. Let's get started on creating this showstopper.
Ingredients for butterflied pork roast
Restaurant-quality pork roast starts with these twelve precision ingredients and expert technique.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Roast (bone-in) 🍖 | 4 lb | Center-cut loin, butterflied |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed (2-inch pieces) |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Coarse grind for texture |
| Garlic Cloves 🧄 | 8 cloves | Smashed, not minced |
| Fresh Rosemary 🌿 | ¼ cup | Needles finely chopped |
| Fresh Thyme 🌿 | ⅛ cup | Leaves only, stems removed |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High smoke point preferred |
| Heavy Cream 🥛 | ¼ cup | Full-fat for richness |
| All-Purpose Flour 🌾 | 1 tbsp | For dredging |
| Butcher's Twine 🧵 | 1 piece | 18-inch length |
| Vegetable Oil 🫒 | ½ cup | For searing |
The pork roast is non-negotiable—center-cut loin with visible marbling ensures both crispy edges and juicy interior. Local butcher shops often carry this cut pre-butterflied, saving you the effort. If sourcing whole, look for a roast with 1-inch fat cap and even thickness. The butter must be cold; pull it from the fridge 30 minutes before use to ensure proper sear. Fresh herbs are critical here—Whole Foods or Trader Joe's carry high-quality rosemary and thyme that elevate the dish beyond standard seasoning.
No fresh rosemary? Dried at one-third the amount works in a pinch, though texture suffers. Substitute heavy cream with half-and-half if unavailable, but expect slightly less richness. For the butterflying process, butcher's twine is essential—regular string won't hold. The olive oil should have a high smoke point (410°F+) to prevent burning during searing. If your roast is thicker than 1.5 inches, trim slightly to ensure even cooking. The flour dredge is optional but creates an incredible crispy crust when seared properly.
Store any unused herbs in damp paper towels wrapped in plastic for up to 5 days. Leftover roast reheats best in a 350°F oven for 15-20 minutes with a splash of water or broth to maintain moisture. Portion the butter into 1-ounce cubes and freeze for up to 6 months in an airtight container. This roast method yields impressive leftovers—perfect for sandwiches or tacos the next day.

Step-by-step instructions for butterflied pork roast
Master this technique to achieve restaurant-quality pork with crispy edges and tender, juicy meat throughout.
Butterfly and Season the Pork Roast
Begin by placing the 4 lb pork roast (bone-in) on a cutting board with the bone side down. Using a sharp boning knife, carefully cut through the thickest part of the roast, stopping just before you reach the bone. Repeat this process until you've made 3-4 deep cuts that allow you to fan out the meat like a book. This creates the butterflied shape that cooks more evenly.
Pat the butterflied roast completely dry with paper towels—this is crucial for crispy edges. In a small bowl, combine the 1.5 tbsp kosher salt and 1 tsp freshly ground black pepper. Generously season both sides of the pork, pressing the salt and pepper into the meat so it adheres well. Let the seasoned pork rest at room temperature for 30 minutes while you prepare the herb butter.
Create the Herb Butter and Prepare the Pan
In a food processor, combine the 0.5 cup unsalted butter, 0.25 cup finely chopped fresh rosemary, 0.125 cup fresh thyme leaves, 8 smashed garlic cloves, and 2 tbsp extra-virgin olive oil. Pulse until the mixture is evenly distributed but still slightly textured. Remove the herb butter from the processor and roll it into a log. Chill while you prepare the pan.
Heat a large oven-safe skillet over medium-high heat until very hot. Add the 0.5 cup vegetable oil and let it get shimmering hot. This high heat is essential for creating that perfect crispy crust on the pork. While the oil heats, flatten the chilled herb butter log and press it onto the center of the butterflied pork, covering it completely.
Pan-Sear for Crispy Edges
Carefully place the butterflied pork into the hot skillet, pressing down gently to ensure good contact with the oil. Sear for 3-4 minutes per side until the edges develop a deep golden brown color and the butter begins to crisp. The pork should release easily from the skillet—if it sticks, let it cook a bit longer before attempting to flip.
Remove the pork from the skillet and transfer it to a wire rack set over a baking sheet. This allows air to circulate underneath, preventing soggy skin. Let the pork rest for 5 minutes while you prepare the oven. Preheat your oven to 400°F and place the skillet from earlier in the oven to heat up.
Finish in the Oven for Perfect Doneness
Return the pork to the hot skillet and place it in the preheated oven. Roast for 20-25 minutes until the internal temperature reaches 145°F when measured with a meat thermometer in the thickest part of the meat. The pork will continue to rise to 150°F as it rests, which is the ideal safe temperature for juicy pork.
While the pork finishes in the oven, prepare a quick pan sauce. Remove the skillet from the oven and place it on the stovetop over medium heat. Sprinkle the 1 tbsp all-purpose flour over the browned bits in the pan and whisk to combine. Gradually whisk in the 0.25 cup heavy cream until the sauce thickens slightly. Taste and adjust seasoning with additional salt and pepper if needed.
Rest and Serve with Herb Butter Sauce
Transfer the pork to a cutting board and tent loosely with aluminum foil. Let it rest for 10-15 minutes before slicing—this crucial step allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful. The pork should be fork-tender with a crispy, golden-brown exterior that gives way to tender, juicy meat inside.
Slice the pork against the grain into ½-inch thick portions and serve with the herb butter sauce spooned over the top. The combination of crispy edges, tender meat, and rich herb butter creates a perfect balance of textures and flavors that will impress even the most discerning diners.
Pro Tips For Making Butterflied Pork Roast
- USE A SHARP KNIFE: The butterflied cut is where this dish shines, but a dull blade turns it into a struggle. I learned this the hard way—after fighting through a stubborn roast, I switched to a 6-inch chef’s knife and sliced through the connective tissue like butter. No need for a cleaver; precision matters more than brute force.
- SALT THE GARLIC SLICES: Those garlic cloves aren’t just flavor—they’re the crust. Toss the minced garlic (or whole cloves if you’re lazy) with a pinch of kosher salt before pressing them into the butterflied pork. The salt draws out moisture, helping the garlic caramelize faster and stick better. (Yes, even if you’re impatient like me.)
- START LOW, THEN CRANK IT: The first 20 minutes at 325°F—no skips—guarantees even cooking without drying out the edges. After that, bump to 425°F for the last 15-20 minutes to brown the butter and crisp the skin. I used to rush the high heat, and the pork always came out uneven. Patience here makes all the difference.
- SKIP THE FOIL AFTER SEARING: Covering the roast too soon traps steam and turns the crust soggy. Let the butterflied pork sear skin-side down for 8-10 minutes until golden, then flip and roast uncovered. The exposed surface gets that maillard magic while the inside stays juicy. (Your future self will thank you.)
Storing and reheating this dish
Refrigerator Storage
Leftovers store beautifully in the fridge for up to 4 days when properly handled. Let the pork cool completely before transferring to an airtight container—I prefer glass for even reheating.
Portion into ½-inch slices with the herb butter sauce for easy grab-and-go meals. The crispy edges stay intact better when stored flat rather than stacked. 🥬
Freezer Prep
For longer storage, freeze cooked pork for up to 3 months using heavy-duty freezer bags. Squeeze out all air before sealing to prevent freezer burn. I like to freeze individual portions with a 1 tsp herb butter sauce in each bag for quick reheating.
Label with the date and portion size—this roast makes 6 generous servings. 🧊
Oven Reheating
My preferred method maintains crispy edges while restoring juiciness. Place slices on a baking sheet at 350°F for 10-12 minutes, then finish under the broiler for 1-2 minutes to restore crispiness.
Add a splash of water or broth to prevent drying. For larger portions, cover loosely with foil during the initial reheating. ⏰
Skillet Refresh
For restaurant-quality results, reheat in the same skillet used for cooking. Heat over medium heat with 1 tbsp vegetable oil, then add slices for 2-3 minutes per side. Add a dollop of fresh herb butter while reheating for maximum flavor. This method restores the crispy crust perfectly. 🔥
Microwave Shortcut
When time is tight, use the microwave on 50% power for 1-2 minutes covered with a damp paper towel. Add 1 tsp heavy cream to maintain moisture.
This method works best for quick lunches but won't restore the crispy texture. I reserve this for busy weekdays when I'm short on time. ⚡
Leftovers Reinvention
Transform reheated pork into pork fried rice using 2 cups day-old rice, 1 egg, and 2 tbsp soy sauce**. Or make crispy pork tacos with corn tortillas and pickled onions.
The herb butter sauce works perfectly on top of mashed potatoes too. Get creative—this roast deserves a second life! 🌟
Nutrition facts
Frequently asked questions
What cut of pork works best for butterflying?
A center-cut pork loin with a 1-inch fat cap is ideal—it stays juicy while developing crispy edges. Look for a bone-in roast (typically 4-5 lbs) with even thickness for uniform cooking. Local butcher shops often carry this pre-cut for convenience.
Can I substitute bone-in pork for boneless?
Boneless pork will cook faster and may dry out more easily. If using boneless, reduce oven temperature to 375°F and monitor closely—it needs about 10-15 minutes less total cooking time. The butterflying technique still works, but the meat will be thinner and more delicate.
How do I know when the pork is fully cooked?
Use a meat thermometer to check the thickest part—it should reach 145°F internally. The pork will rise to 150°F while resting, which is the ideal safe temperature. If your pork feels firm to the touch but the thermometer reads below 145°F, it needs a few more minutes in the oven.
Why does my butterflied pork turn out dry?
Overcooking is the most common cause—pork continues cooking after removal from heat. Always rest for 10-15 minutes before slicing. Also check your thermometer placement (bone-side vs. meat) and avoid cutting into the meat until fully rested. For extra juiciness, baste with melted herb butter during the last 5 minutes of cooking.
Can I make this ahead of time?
Yes! Cook the pork completely, then cool and refrigerate for up to 4 days. Reheat slices in a skillet with fresh herb butter for 2-3 minutes per side to restore crispiness. For parties, assemble the herb butter log and refrigerate it separately—press it onto the pork just before searing for maximum flavor impact.
