Tips on How to Cook a 5 Lb Pork Loin

Vegetables – The vegetables should be cut as small as the ones in my photo, and my roast took 90 minutes to cook because it weighed nearly 6 pounds.

Carrots should be cut no wider than 12 inches, and potatoes should be cut no thicker than 12 inches to guarantee that they are cooked by the time the roasting time is over. Vegetables of a smaller size will cook faster.

Spices and seasonings – Spices are an important element in cooking recipes, a tiny quantity or a large amount will provide your cuisine with the flavor it needs to keep you coming back for more. You always use salt, pepper, onion powder, garlic powder, Montreal seasoning, and paprika anytime you want.

Butter and olive oil – Using butter and olive oil is quite significant. It aids in the formation of a moisture barrier on the top fat of the roast, as well as providing moisture to the veggies and the bottom of the pork loin once melted.

Searing – Starting with a high heat of 450°F to sear in the fluids is what makes this the best pork loin dish around. When you sear them in, you don’t lose as much moisture to the oven. The oven is then turned down and the pork loin is cooked at a lower temperature than usual, resulting in moist roast pork.

Browning the pork loin – Well, I feel that browning the pork loin before roasting it is a personal choice. Browning the pork loin on the outside may add a lot of flavors and create a sear crust. This will help to lock in the meat’s natural juices, resulting in a more flavorful end product.

Follow my stey by stey guide outlined below:

  • Preheat the oven to 450 degrees Fahrenheit.
  • You can combine the butter, oil, garlic, rosemary, salt, and pepper in a small bowl and stir until paste forms.
  • You can remove excess moisture from the pork loin with a paper towel, then rub ⅔ of the seasoning mixture onto the roast, make you are covering the top and sides.
  • Then proceed to place the pork loin in the bottom of the big roaster.
  • Then arrange the vegetables around the roast.
  • You can apply the remaining seasoning mixture to the vegetables with a pastry brush.
  • You can cover the roast with foil after removing it from the oven. Allow 10 minutes for it to rest before slicing and serving.
  • Roast for 15 minutes in the preheated oven, then reduce the temperature to 300° F. Do not take the oven out of the oven.
  • You should allow the roast to cook for another 20-25 minutes per pound of meat – that’s just over 2 hours for a 5 lb pork loin- until an internal temperature of 140° F is reached when a meat thermometer is placed into the center.
  • You can cover the roast with foil after removing it from the oven when the meat is ready.
  • You have to allow 10 minutes for the pork loin to rest before slicing and serving.

You can even use the resting time to finish your other side dishes and make gravy with the lovely brown juices in the roasting pan.

I cook mine at 135-140°F, but this isn’t suggested for safety reasons. According to the National Pork Board, a safe temperature of 145°F and a cooking period of 20-25 minutes per pound are the correct times and temperatures.
