Pork temperature

We highly recommend purchasing an instant-read thermometer if you don’t already have one. This is a tool you’ll use often while cooking, and allows you to get the perfect temperature every time when cooking meat.

According to the USDA, the safe internal temperature for pork is 145F/62.8C, with a rest time of at least 3 minutes. With this temperature, the center of your tenderloin may be slightly pink. If you cook the pork past this temperature, your meat will be drier and tougher.

Spice variations

You can use just about any spice blend you’d like in this recipe. If you prefer something more simple, perhaps try salt, pepper, and smoked paprika. Or you could add some spice with a cajun seasoning mix or give the meat an Italian flavor with an Italian seasoning blend.

Searing the meat

Don’t skip searing the meat! This step is part of what gives the tenderloin a nice crispy crust. The crispy crust is really delicious when paired with the juicy, tender center of the meat.

Cooking the tenderloin

We highly recommend cooking the meat on a baking rack if possible. Raising the meat slightly off the baking sheet helps the meat cook more evenly, and also helps contribute to the crisp crust. If you don’t have a baking rack, you can cook the tenderloins directly on a lined baking sheet.

Cooking the tenderloin

Pork tenderloin is a very versatile meat and pairs well with almost any side dish! Check out our side dishes to find delicious vegetable sides to go with your roasted pork tenderloin.

Frequently Asked Questions

Is this low-carb pork tenderloin recipe gluten-free?

Storage and Reheating Guidelines

  • Make-ahead: Pork tenderloin has the best flavor and is the juiciest when cooked fresh. We highly recommend cooking this recipe fresh rather than making it ahead of time and reheating.
  • Storing leftovers: Store leftover pork tenderloin in an air-tight container in the refrigerator for up to 3-4 days. 
  • Freezing instructions: Freeze roasted pork tenderloin in an air-tight, freezer-safe container for up to 3 months. Thaw in the refrigerator overnight.
  • To reheat: Reheat in a skillet on low heat, in a toaster oven, or in the microwave on half power. Be cautious to only reheat the meat until warm, and do not cook it too long, or it will dry out.

This recipe is perfect for individuals with diabetes who are seeking a flavorful, protein-packed dish that won’t spike their blood sugar levels. The tender and juicy pork tenderloin, seasoned to perfection, provides a satisfying dining experience that can be enjoyed with a variety of side dishes.

Pork tenderloin, known for its tenderness and mild flavor, is a lean cut of meat that fits well into a diabetic-friendly diet. It is an excellent source of high-quality protein and essential nutrients such as vitamins B6 and B12, selenium, and zinc. Oven-roasting the pork tenderloin ensures it remains juicy and succulent while allowing the flavors to intensify and develop.

Pork Tenderloin Preparation Tips

  • Choose a fresh, high-quality pork tenderloin from a trusted source. Look for meat that is pink in color, firm to the touch, and has a minimal amount of visible fat.
  • Before cooking, remove the pork tenderloin from the refrigerator and allow it to sit at room temperature for about 20 minutes. This step ensures more even cooking.
  • Season the pork tenderloin generously with your choice of herbs, spices, or a marinade. Popular options include garlic, rosemary, thyme, paprika, or a combination of these flavors. Marinating the pork overnight will infuse it with even more flavor.
  • For a beautifully browned exterior, sear the pork tenderloin in a hot skillet for a few minutes on each side before transferring it to the oven.
  • To ensure the pork reaches a safe internal temperature, use a meat thermometer. The USDA recommends cooking pork to an internal temperature of 145°F (63°C) with a 3-minute rest time.

Variations and Serving Suggestions

  • Mustard and Herb Crust: Create a flavorful crust by mixing Dijon mustard with a combination of herbs such as rosemary, thyme, and parsley. Spread the mixture over the pork tenderloin before roasting for a tantalizing twist.
  • Balsamic Glaze: Drizzle a balsamic glaze over the roasted pork tenderloin for a tangy and slightly sweet flavor profile. Reduce balsamic vinegar with a touch of honey or sugar substitute until it thickens into a glaze-like consistency.
  • Fresh Fruit Salsa: Enhance the pork’s taste with a refreshing fruit salsa. Combine diced mango, pineapple, red bell pepper, red onion, cilantro, lime juice, and a pinch of salt. Serve the salsa on top of the sliced pork tenderloin for a burst of tropical flavors.

    Not one to leave comments. This recipe made the most juicy and tender pork I’ve ever eaten. I believe because of searing the meat before baking. Will try this same method with different spice varieties in the future also. 5 stars.

    1. Thank you for your feedback, Ramesh! We’re so glad you enjoyed this recipe. Let us know how your other spice variations turn out, if you’d like to share we’d love to try them also 🙂
