Keto Oven Roasted Pork Loin Recipe
My love of pork runs deep. One of the first recipes I shared with you is my Pork Chops and Sauerkraut. It's quite popular and I do hope you try it. Today's recipe has become just as popular recipe with the hubs and me. So rich and tasty. The sauce is ah-mazing.
Main Ingredients
Pork loin is so easy to cook and can be served for a quick family dinner or an elegant dinner with family and friends. Use either a marinated lemon-herb pork roast or follow instructions in the recipe to add seasoning.
Mayonnaise will be the base of the aioli or lemon sauce. Obviously lemon is a must. Use either fresh or jarred juice. Fresh parley will add a tasty flavor to the pork and the sauce.
Garlic, my favorite ingredient, which can also be either fresh or jarred.

How to cook a pork loin roast
This is an overview of the recipe. The full instructions are below in the recipe card.
- Preheat oven to 400°F. Place the loin on a roasting pan or baking tray. If not using a marinated pork, make a quick rub of lemon juice, olive oil, minced garlic, and chopped parsley. Rub it on the meat.
- Roast the pork until the internal temperature is at least 145°F. This will take about 40-50 minutes.

Recipe Tips and FAQs
- Pork is naturally keto-friendly and a great protein for a low-carb diet or on a low-sugar diet.
- Pork can be salty, therefore, I have not added salt to the seasonings. It is best to taste everything after it has cooked to see if salt is needed.
- Roast tender cuts of pork at higher temperatures such as 375°F so the meat cooks quickly and stays moist.
- Do not cover the meat with aluminum foil while cooking so the exterior gets brown and crispy.
- Use a digital meat thermometer to get an accurate temperature of cooked meat.
- Let the meat rest for about 10 minutes to allow the juices to set. This ensures a juicy roast, every time.
- Store leftovers in the fridge, covered, for up to 2 days.
