Donna Black says
I cooked this last night. It was delicious and so easy to make. My son woke up this morning disappointed that there weren't any leftovers. This recipe will definitely be a part of our weekly meal rotation.
Cast Iron Keto says
Thanks for sharing Donna! So glad you and your son enjoyed it!
Richard Wadsworth says
Really lovely this dish. Thanks for sharing
Lamar says
Wow! This was really good. I seasoned the tenderloin with the herbs mixture, kosher salt and black pepper. Served it with roasted asparagus ( Pensays Tuscan Sunset seasoning)and parmesan cheese. Delicious!
Lorrie MN Keating says
The recipe calls for 1 1lb tenderloin. I'm assuming that is a typo, as 8 servings means 2oz per.
Cast Iron Keto says
Hi Lorrie, thanks for pointing that out! Yes, it should read (2) 1-pound pork tenderloins.
Tom says
How many oz then are considered a serving? Excited to try it
Cast Iron Keto says
4 ounces, hope you give it a try!
Anthony Crivello says
Cooked this meal last night! WOW is all I can say, from the sauce to the tenderloin being juicy in every bite, I wanted to eat the entire tenderloin. 10/10 unreal and amazing recipe!
Arianne Leslie says
Any chance you could help me convert this to use with a regular pork loin?
It'd be much appreciated!
Adam says
It was soft and juicy. I don’t follow recipes to the T, and I don’t think people should either all the time. I kept most of the ingredients the same but I changed the process a little bit. I cut the pork tenderloin at an inch and a half before cooking, i seasoned it with pink salt, pepper, minced garlic, thyme/rosemary/sage. I put them in a frying pan with about half a stick of butter, medium-high heat just to sear them. Then I put them in the air fryer. 400F for 3 min, flip them 3 more min, flip them and then again 3 more minutes. I used a prego Parmesan and garlic sauce to top it lightly, it has 3g of carbs for a 1/4 cup so I just dazzled it on. 10/10 good inspiration.
Paula Brubaker says
Thank you for clarifying the amount of pork. Saw two 1 # tenderloins, but directions just spoke to one tenderloin. Follow keto and try to keep up closely with the macros. It helped to have you clarify in the reviews. I will count 4 Oz per serving.on the 1. Tenderloin.
Kay says
Delicious, recipe will easier next time I make it.Husband loved it. Side dish stewed cabbage with onion and butter.
Kim says
I would like to clarify -- is one supposed to SLICE the garlic and insert it into the tenderloin? Because the ingredient list says coarsely minced garlic, yet the recipe states "sliced garlic." Just trying to clarify this.
Cast Iron Keto says
Whoops, sorry about that. Fortunately, either option works just fine.
Colleen Richards says
Excellent and So Easy!
I put a twist on this. I stuff the tenderloin with garlic, brush with avocado oil )after rinsing & patting dry), next I combine the salt, pepper and Italian herbs, the I sprinkle to cover entire tenderloins before browning. Since I brushed the pork with avocado, I omit adding ant to the skillet. This reduces the amount of oil used.
Rhonda Lahnakoski says
I assume we are just rubbing the herb mixture on the tenderloin as I can’t imagine being able to stuff it into holes made by a fork. Am I missing something or just being too literal 😂
Mr. Nomad says
Made this for dinner tonight with asparagus. Easy to make. Very tasty, well seasoned, and a nice crust from browning the meat. Cooked in the oven without a lid.
Cast Iron Keto says
Hi Nomad,
It's a fantastic dinner choice! 😊 So glad it was tasty with a nice crust. Happy cooking! 🍽️👏
