To show you just how amazing your leftovers can be, we’re going to do a deep-dive on the undisputed champion of leftover transformations: a quick and easy Pork Fried Rice.

Feature Recipe: 15-Minute Leftover Pork Fried Rice

This is the fast, flavorful, one-pan wonder your leftover pork was dreaming of.

Ingredients: Your Speedy Stir-Fry Squad

• 2 cups cold, cooked rice (Day-old rice is perfect!)
• 1 cup leftover pork tenderloin, diced into small cubes
• 2 tablespoons vegetable or sesame oil, divided
• 1 small onion, chopped
• 1 cup frozen peas and carrots, thawed
• 2 cloves garlic, minced
• 2 large eggs, lightly beaten
• 3 tablespoons soy sauce
• 1 teaspoon grated fresh ginger (optional)
• Sliced green onions, for garnish

The Golden Rule of Fried Rice:

• You must use cold, day-old rice. Fresh, warm rice is too moist and will steam in the pan, resulting in a sticky, gummy mess instead of distinct, beautifully fried grains. This is a non-negotiable, my friend.

Tools & Kitchen Gadgets Used: Your Wok-and-Roll Kit

• A Large Skillet or Wok
• A Sharp Knife and Cutting Board
• A Spatula or a Wooden Spoon
• Small bowls for your prepped ingredients

Step-by-Step Instructions: The Path to Fried Rice Perfection

This moves FAST. Have all your ingredients chopped and ready next to the stove before you start.

1. Prep Your Station: Dice your leftover pork, chop your onion, mince your garlic, and lightly beat your eggs. Have your cold rice, peas and carrots, and soy sauce ready to go.
2. Scramble the Eggs: Heat 1 tablespoon of the oil in your large skillet or wok over medium-high heat. Add the beaten eggs and scramble them quickly, breaking them into small pieces. This should only take about a minute. Remove the cooked eggs from the pan and set them aside.
3. Sauté the Veggies: Add the remaining 1 tablespoon of oil to the hot skillet. Add the chopped onion and stir-fry for 2-3 minutes until softened. Add the minced garlic and grated ginger (if using) and cook for another 30 seconds until fragrant. Toss in the peas and carrots and cook for another minute.
4. Fry the Rice: Add the cold, cooked rice to the skillet. Use your spatula to break up any clumps. Stir-fry for 2-3 minutes, tossing the rice with the vegetables, until it’s heated through.
5. The Grand Finale (Add the Pork!): Now for the crucial step. Turn off the heat. Add the diced leftover pork tenderloin and the scrambled eggs back into the pan. Pour the soy sauce over everything.
6. Toss and Serve: Gently toss everything together. The residual heat from the rice and the pan will be more than enough to warm the pork through without overcooking it. Garnish with sliced green onions and serve immediately.

Common Mistakes to Avoid (For the Fried Rice)

• Using Warm Rice: This will result in a sticky, mushy tragedy. Only use cold, dry, day-old rice.
• Adding the Pork Too Early: If you add the pork in with the raw veggies, you will be cooking it for a second time, turning it into tough little cubes of sadness. Add it at the very end, off the heat.
• A Lukewarm Pan: Fried rice needs high heat to get that slightly crispy texture and “wok hei” flavor. Don’t be afraid to get your skillet nice and hot.

More Genius Ways to Use Leftover Pork Tenderloin

Ready for more? Here are a few other ways to give your pork a delicious second act.

• Pork Tenderloin Sliders with a Tangy Slaw: Thinly slice your cold pork tenderloin. Pile it onto small, soft slider buns. Top with a generous amount of your favorite BBQ sauce and a quick slaw made from shredded cabbage, mayo, and a splash of vinegar. The sauce and slaw provide the moisture, so you don’t even need to reheat the pork!
• Creamy Pork and Mushroom Pasta: Sauté sliced mushrooms and garlic in a pan. Add a splash of white wine (optional) and some heavy cream to create a quick, creamy sauce. Let it simmer and thicken. Cook your favorite pasta. At the very end, turn off the heat and toss the cooked pasta and the diced leftover pork into the sauce to warm through.
• The Ultimate Pork Salad Sandwich: This is my personal favorite, IMO. Finely chop your cold leftover pork tenderloin. Mix it with mayonnaise, finely chopped celery, red onion, and a little Dijon mustard. Season with salt and pepper. It’s like a classic chicken salad, but with a porky twist. Serve on a croissant or with crackers.

FAQ Section: All Your Leftover Pork Predicaments, Solved

You have questions about this lean leftover. Let’s get them answered.

• Q: What is the absolute best way to reheat a slice of pork tenderloin so it doesn’t dry out? A: The key is to add moisture. Place the slices in a skillet with a splash of broth or water over low heat. Cover the pan and let it gently steam for just a minute or two until warmed through.
• Q: How long is leftover pork tenderloin good for in the fridge? A: Stored properly in an airtight container, it will last for 3 to 4 days.
• Q: Can I freeze leftover pork tenderloin? A: Yes! It’s best to freeze it whole, if possible, to retain moisture. Wrap it tightly in plastic wrap and then foil, and freeze for up to 3 months. Thaw overnight in the refrigerator.
• Q: Should I slice the pork before I store it? A: For the best results, store the leftover tenderloin whole. This helps it retain as much moisture as possible. Slice it cold right before you use it in one of these recipes.
• Q: My leftover pork is already a little dry. Can it be saved? A: Yes! Your best bet is to use it in a recipe with plenty of sauce or moisture, like the Creamy Pork Pasta or the Pork Salad Sandwich. The sauce will help to mask the dryness and add richness back in.
• Q: Can I just microwave it? I’m in a hurry! A: You could. But you could also use a beautiful silk scarf to wipe up a spill. It’s a waste of something good. If you absolutely must, use a lower power setting and place a damp paper towel over the pork to help it steam gently instead of turning into rubber.
• Q: What kind of sauces and flavors pair well with pork? A: Pork loves both sweet and savory flavors. Think BBQ sauce, honey mustard, creamy mushroom sauces, apple or pear chutneys, and Asian-inspired sauces with soy and ginger.
