This microwave pork roast recipe transforms a weeknight dinner into a juicy, restaurant-quality meal in just 15 minutes. After years of perfecting pork roasts in my professional kitchen, I discovered that the microwave—when used correctly—can deliver tender, pink-centered perfection without drying out the meat.
The secret lies in precise timing, strategic basting, and letting the meat rest properly, techniques I've refined while cooking 2,000 pounds of pork weekly at my restaurant.
What sets this method apart is how it preserves moisture while achieving that ideal doneness—juicy throughout with a slightly caramelized exterior. We'll use a simple seasoning blend of salt, pepper, and garlic powder, then baste the roast with its own juices during cooking to lock in flavor.
The microwave's even heat distribution ensures no cold spots, unlike traditional oven methods that can leave some areas undercooked. This approach is perfect for busy weeknights when you still want a satisfying, hearty meal.
The result is a pork roast with a tender, melt-in-your-mouth texture and just enough pink in the center to satisfy even the most skeptical meat lovers.
The beauty of this recipe is its versatility—serve it sliced for sandwiches, shredded for tacos, or as the centerpiece of a family-style dinner with roasted vegetables and mashed potatoes. The microwave technique might sound unconventional, but trust me, it delivers professional-quality results with minimal effort.
We'll cover everything from selecting the right cut of pork to proper resting times and microwave safety tips. This isn't just another quick meal—it's a method that transforms how you think about cooking pork at home. Let's get started on creating your most tender, flavorful pork roast yet.
Ingredients for microwave pork roast
The secret to juicy, pink pork lies in these simple ingredients and precise technique.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin Roast 🥩 | 2 lb | Center-cut for even cooking |
| Kosher Salt 🧂 | 1 tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Cracked peppercorns preferred |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Unsalted Butter 🧈 | 2 tbsp | Cold for basting |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ⅛ cup | Or 1 tsp dried thyme |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for basting |
| Low-Sodium Chicken Broth 💧 | ¼ cup | For basting liquid |
| Fresh Parsley 🌿 | ⅛ cup | Chopped for garnish |
| Microwave-Safe Roasting Pan 🍽️ | 1 whole | With lid or foil cover |
The pork loin is non-negotiable here—center-cut ensures even cooking without tough edges. Costco or Whole Foods carry excellent pre-trimmed roasts, but if you're cutting your own, look for a piece with good marbling. Fresh herbs make all the difference (the good stuff, not the dried packets), so hit the farmers market if you can. I always grab extra rosemary—half goes on the pork, half gets tossed in the basting liquid. The kosher salt matters too: Diamond Crystal dissolves better than table salt, so you get even seasoning without over-salting.
No fresh rosemary? Dried at one-third the amount works in a pinch, but trust me, it's worth the trip to the store. Out of chicken broth? Water plus 1 tsp soy sauce mimics the depth. The butter should be cold when you start basting—microwave it 15 seconds to soften if needed. For the herbs, I usually wash and dry them thoroughly before chopping (wet herbs steam instead of crisp up). The olive oil is just for flavor—don't skimp on the extra-virgin kind. And if you're feeling fancy, add a pinch of smoked paprika to the seasoning mix.
This roast reheats beautifully—30 seconds in the microwave with a splash of broth brings it back to perfection. Store leftovers in the fridge for 3-4 days or freeze for 2 months (portion into single servings first). The basting liquid makes great gravy—just strain it and reduce on the stove. For the best texture, let the roast rest 10 minutes after cooking before slicing. That's when all the juices redistribute—don't skip this part, even if you're impatient (I know the struggle).

Step-by-step instructions for microwave pork roast
Here's how to transform a simple pork roast into tender, juicy perfection using just your microwave.
Prep the Pork Roast for Even Cooking
Start by placing the 2 lb boneless pork loin roast in the microwave-safe roasting pan. Pat it dry thoroughly with paper towels—this helps create a better sear and prevents the exterior from becoming soggy. I like to use the pan's lid or foil cover to trap steam while still allowing some airflow.
In a small bowl, combine the 1 tbsp kosher salt, 1 tsp freshly ground black pepper, and 1 tsp garlic powder. Rub this mixture all over the pork, pressing gently to ensure even distribution. The salt will draw out moisture initially, but don't worry—it'll return as juices during cooking. Let the seasoned roast sit at room temperature for about 10 minutes before microwaving to ensure even cooking.
Create the Basting Mixture
In a separate microwave-safe bowl, melt the 2 tbsp unsalted butter along with the 1 tbsp extra-virgin olive oil. Add the 0.25 cup finely chopped fresh rosemary and 0.125 cup fresh thyme leaves, stirring until everything is well combined. This aromatic mixture will become our basting liquid, infusing the pork with incredible flavor as it cooks.
While the butter melts, pour the 0.25 cup low-sodium chicken broth into the roasting pan with the pork. This liquid will help create steam, keeping the meat moist during the cooking process. The broth also adds depth of flavor that complements the herbs beautifully.
Microwave with Precision Timing
Cover the roasting pan tightly with its lid or foil. Place the pan in the microwave and cook on high power for 8 minutes. This initial cooking period gets the pork started and begins breaking down the connective tissues. After 8 minutes, carefully remove the pan and use tongs to flip the roast over, basting it generously with the melted butter mixture.
Return the pan to the microwave and cook for another 7 minutes. The total cooking time should be about 15 minutes, but this may vary slightly depending on your microwave's wattage. The key is to cook until the internal temperature reaches 145°F—this ensures juicy, pink-centered perfection without overcooking.
Rest and Garnish for Maximum Juiciness
Once the pork reaches the proper temperature, remove it from the microwave and let it rest for 5 minutes. This resting period is crucial—it allows the juices to redistribute throughout the meat, preventing them from running out when you slice. During this time, you can prepare your garnish by chopping the 0.125 cup fresh parsley.
After resting, transfer the pork to a cutting board and slice it against the grain into 0.5-inch thick slices. The meat should be tender with a juicy interior and slightly crisp edges from the basting. Spoon any remaining basting liquid from the pan over the sliced pork, then garnish with the chopped parsley. Serve immediately with your favorite sides for a restaurant-quality meal created in minutes.
Pro Tips For Making Microwave Pork Roast
- Cut the Roast First: Slice the pork loin into 1-inch thick medallions before microwaving—thicker slices stay tough and dry, while thinner ones cook evenly and stay juicy. I learned this the hard way after serving rubbery pork that had been microwaved whole.
- Salt Like It’s Worth It: Generously coat the pork with kosher salt and black pepper at least 30 minutes before cooking—this seasoning penetrates deeper than you think. Skip this, and your pork will taste bland no matter how well it cooks.
- Butter in Layers: Don’t just dump butter on top—score the pork in a crosshatch, then press garlic powder between the cuts and dot with softened butter. The butter melts into the meat instead of pooling, making every bite richer.
- Pause at 70%: Microwave the pork for 70% of the total estimated time, then flip and cover loosely with a damp paper towel. Let it sit 2 minutes before finishing—this keeps it from drying out when you hit the last 30% of cooking. (Yes, even if you’re impatient like me.)

I always double-check my herb quantities because fresh herbs amplify these nutritional benefits significantly.
Low-Calorie Comfort
At just 180 calories per serving, this roast satisfies cravings without derailing your diet. The microwave method preserves moisture better than oven-roasting, so you get tender texture with fewer calories—a win-win for health-conscious cooks.
I've used this technique for clients recovering from injuries who need high-protein meals without heavy portion sizes. The chicken broth in the basting adds flavor without significant calories.
Digestive Benefits
The garlic and rosemary in our seasoning blend act as natural digestive aids, while the lean pork provides easily digestible protein compared to fattier cuts. The microwave cooking method actually helps break down connective tissues more efficiently than traditional methods, making the protein more bioavailable.
I've noticed my restaurant guests with sensitive stomachs tolerate this preparation better than slow-cooked pork.
Versatile Nutrition
This roast works perfectly in balanced meals—pair it with roasted vegetables for fiber or whole grains for complex carbs. The basting liquid can be strained and used as a low-sodium gravy, adding flavor without excess salt.
I often serve this to my family during weeknights when we need a quick but nutritious dinner that everyone will enjoy. The microwave method lets me prepare it while handling other meal components simultaneously. ✨

Frequently asked questions
Can I use a different cut of pork for this microwave method?
While this recipe works best with boneless pork loin, you can try tenderloin or even a small bone-in rib roast. For bone-in cuts, reduce cooking time by 2-3 minutes and check for doneness at 140°F internal temperature. Avoid fatty cuts like pork shoulder—they release too much fat in the microwave and can become greasy. Always pat the meat dry before seasoning for best results.
Why does my microwave pork roast turn out dry?
Overcooking is the #1 cause of dryness. Use a meat thermometer to check for 145°F internal temp—never guess! Also, skipping the resting time causes juices to escape when slicing. For extra moisture, add 1 tbsp apple cider vinegar to the basting liquid. I've found that microwaving on medium power (50%) instead of high helps distribute heat more evenly.
How do I adjust cooking time for different microwave wattages?
Most standard microwaves (1000-1200 watts) work with the 15-minute total time, but lower wattage (800-900 watts) may need 2-3 extra minutes. High-wattage (1400+ watts) might cook faster—start checking at 12 minutes. The key is monitoring internal temperature. I always recommend starting with the full time, then adjusting by 1-minute increments. A meat thermometer is your best friend here!
Can I make this pork roast ahead of time?
Yes! Cook the roast as directed, then let it cool completely before refrigerating. Store in an airtight container for up to 3 days. To reheat, microwave slices for 30 seconds with a splash of water or broth. For best texture, I recommend reheating only what you need rather than the whole roast. The microwave method actually preserves texture better than oven reheating for this dish.
What are some great side dishes to serve with this?
This juicy roast pairs perfectly with garlic mashed potatoes (use the leftover basting liquid for flavor!), roasted Brussels sprouts with bacon, or a simple green salad with vinaigrette. For a Southern twist, try cornbread and collard greens. I often serve it with microwaveable quinoa** (cook separately) for a complete meal. The herb flavors in the roast complement earthy vegetables beautifully.
