This garlicky black pepper stir-fry transforms simple pork into a restaurant-worthy dish with minimal effort. The combination of tender meat, bold garlic, and cracked pepper creates an irresistible depth of flavor.
I developed this recipe after testing multiple versions in my small Boston kitchen, perfecting the balance between savory and peppery notes. The key is cooking the pork quickly over high heat to maintain its tenderness.
What emerges is a dish with juicy pork pieces coated in a glossy sauce that clings to every bite. The black pepper adds just the right amount of warmth without overwhelming the other flavors.
The entire process takes less than 30 minutes, making it ideal for busy weeknights when you want something special without the fuss.

| Worcestershire Sauce 🫒 | 1 tbsp | For savory complexity |
| Butter 🧈 | 4 tbsp | Unsalted for controlled seasoning |
| Vegetable Oil 🫒 | 2 tbsp | High smoke point for stir-frying |
| Cornstarch 🌾 | 2 tbsp | For velvety sauce texture |

The pork is the star here. Pork tenderloin stays tender and cooks fast—avoid tougher cuts like shoulder. Most supermarkets carry it pre-trimmed, but ask the butcher to cube it if you’re short on time. I grab mine from Whole Foods or Market Basket when it’s on sale. The garlic should be fresh (none of that jarred stuff), and the peppercorns need to be cracked just before cooking for maximum punch.
No oyster sauce? Hoisin or fish sauce works in a pinch (use half the amount). Worcestershire can be swapped for more soy sauce, but the flavor won’t be as deep. For extra richness, add a splash of sesame oil at the end. The cornstarch is key—don’t skip it, or the sauce won’t cling to the pork. Brown sugar can be swapped for honey (trust me, it’s undetectable).
This dish tastes even better the next day once the flavors meld. Store leftovers in an airtight container in the fridge for up to 4 days. Reheat gently to avoid drying out the pork. Freezing isn’t ideal (the texture changes), but it’ll keep for 3 months if needed.

Step-by-Step Instructions for Garlicky Black Pepper Stir-Fry
Here’s the method. Straightforward, tested, works every time.
Step 1: Prep the Pork and Seasonings
Pat the 1.5 lb pork tenderloin dry with paper towels, then cut it into 1-inch cubes. I like to trim any excess fat first so the meat cooks evenly. Place the cubes in a bowl and set aside.
In a small bowl, combine the soy sauce, oyster sauce, Worcestershire sauce, brown sugar, and beef broth. Stir until the brown sugar dissolves completely. This sauce will infuse the pork with rich, savory flavor.
Step 2: Cook the Pork Until Browned
Heat the vegetable oil in a large skillet or wok over medium-high heat until it shimmers. Add the pork cubes in a single layer (work in batches if needed to avoid crowding). Sear undisturbed for 2-3 minutes until the bottoms turn golden brown.
Flip and cook for another 2-3 minutes until all sides are evenly browned. The pork doesn’t need to be fully cooked yet—it’ll finish in the sauce. Transfer to a plate and set aside.
Step 3: Build the Garlicky Black Pepper Sauce
In the same skillet, melt the butter over medium heat. Add the minced garlic cloves and cook for 30 seconds until fragrant but not browned. Stir in the freshly cracked black peppercorns and cook for another 30 seconds to toast them slightly.
Pour in the prepared sauce mixture and bring to a simmer. Sprinkle the cornstarch over the surface and stir constantly for 1-2 minutes until the sauce thickens into a glossy, velvety consistency.
Step 4: Finish and Garnish
Return the pork to the skillet and toss to coat evenly in the sauce. Cook for an additional 2-3 minutes until the pork is fully cooked through and the sauce clings beautifully to each piece.
Remove from heat and garnish with thinly sliced green onions. The dish should have a glossy sheen with visible flecks of black pepper and garlic. Serve immediately over steamed rice to soak up every last bit of the rich sauce.
Pro Tips For Making Pork Salpicao
- Sear on High Heat: Crank the pan to high and sear the pork tenderloin cubes in batches—this gives them that golden crust without steaming them in their own juices.
- Crush the Peppercorns: Lightly crush the black peppercorns before adding them; it releases more flavor than whole ones and sticks better to the pork.
- Don’t Overcook the Garlic: Add the minced garlic only after the pork is browned, then cook for 30 seconds max—I learned this the hard way after burning three batches.
- Use Freshly Ground Pepper: Skip the pre-ground stuff and use freshly cracked black pepper for the finish; it’s more aromatic and actually changes the outcome.
Common Mistakes When Making Perfect Results
Overcrowding the Pan
Cooking all 1.5 lb pork at once creates steam instead of searing, leaving you with rubbery meat. I learned this the hard way in my tiny Boston kitchen. Work in batches to maintain medium-high heat and proper browning.
Skipping the Cornstarch
That 2 tbsp cornstarch isn’t optional—it transforms the sauce from watery to velvety. I tested versions without it, and the sauce just slid right off the pork. Be sure to sprinkle it evenly and stir constantly.
Pre-Cracking Pepper
Freshly cracked black peppercorns release oils that jarred pepper can’t match. I crack mine right before adding to the garlic butter. This simple step makes the dish taste restaurant-quality. 🌶️
Overcooking the Garlic
Burnt garlic turns bitter in seconds. Cook the 8 minced cloves just until fragrant—about 30 seconds—then add the peppercorns immediately. I pull the pan off heat if I’m unsure.
Using Cold Pork
Cold pork lowers the pan temperature, leading to uneven cooking. Let your cubed pork tenderloin sit at room temperature for 15-20 minutes before searing. This ensures even browning.
Skipping the Rest
Let the pork rest 2-3 minutes in the sauce off heat before serving. This lets the juices redistribute. I noticed the difference immediately when I started doing this in my testing.

Frequently Asked Questions
Can I use a different cut of pork?
Pork shoulder works but needs longer cooking. Tenderloin is best for quick, even cooking. Avoid lean cuts like loin as they can dry out.
Why is my sauce too thin?
You likely skipped the cornstarch or didn’t cook it long enough. Simmer the sauce for 1-2 minutes after adding it to thicken properly.
Can I make this ahead of time?
Yes! The flavors meld beautifully. Store in an airtight container for up to 4 days. Reheat gently on the stove.
What if I don’t have oyster sauce?
Substitute with hoisin or fish sauce (use half the amount). The flavor won’t be identical but still delicious.
