My family doesn't like pork much but I like some variety in our menus! I used this recipe & I will definitely keep it! They loved it and. It doesn't need to be marinated for too long to get the great taste. I marinated it for 3 hours and it was just right. I think over night would be too strong. I used the leftovers in a stir fry and it was yummy both ways!

Wow - this blew us away! The simplicity of it was wonderful. I followed recipe exactly and just adding a tablespoon of crushed garlic as others suggested. The steak seasoning I chose was McCormick's Montreal Steak seasoning (that stuff is great!!). My roast was about 2 1/2 lbs. but cooking it for just an hour was perfect. This meat was so juicy and delicious. Thanks submitter!

I followed the recipes exactly and got a moist flavourful roast that my whole family loved. Thanks for the simple and delicious recipe.

I thought I had the best pork loin recipe, but I was wrong! This is great. Of course, the balsamic vinegar flavor is dominant, so if you don't like balsamic vinegar, you won't like the roast. I used a pork rub with rosemary and ginger. Otherwise I followed the recipe exactly. As good as it was straight out of the oven, it was even better the next day cold!

FANTASTIC recipe. My husband loved it. I used Balsalmic Vinegar of Modena and it worked great. I also added 2 Tbsps of freshly pressed garlic to the marinade and I think it added alot to the flavor. I marinated the loin overnight. It was super juicy. Will definitely make this again.

This was fantastic! I used the Balsamic Vinegar of Modena (Monari Federzoni)Even the 2 grandbabies 2-1/2 and 3 ate it! It was not over powering with vinegar at all. Just the right snap and very tender.

Spectacular tasting and so easy! I cut the olive oil in half, but the pork ended up a little dry, so I may have to follow the recipe next time.

I give it 5 stars for the juiciness. I did take some suggestions and added rosemary and a teaspoon of minced garlic. The flavors were very good. I think the two keys to this dish: use a good quality balsamic (as others have said) and let it marinate overnight.

We liked this. I let it marinate overnight. I did not have steak seasoning, but I used 2 tsp of minced garlic and 1 tsp of rosemary as suggested by others. I did not find any of the flavorings to be overpowering. Just a nice way to make a roast.

Turned out incredibly moist and delicious. Received rave reviews. Should have doubled the recipe...

This is an awesome recipe!! I've made this twice for parties and it was a huge hit both times. I pretty much followed the recipe as given the only thing I added was 2 tablespoons of chopped garlic and I marinated this for 48 hours and it produced the most tender juicy pork loin that I've ever had. Definitely use a good quality Balsamic vinegar, I used a low cost one the first time and it was good, but used a high quality Balsamic the last time and it truly does make a huge difference! I'll be making this many more times for sure!

Very good recipe, and gets additional points for being so easy to prepare! I used a pomegrante balsamic and it added sme tangy-fruitiness to it which was very good.

I sliced the loin into 1" slices, left it in marinade 9 hours then baked for 1 hr. Was tender, but no raves from the family.

Made this one tonight...MMMMMM...fantastic!!! Added snipped fresh rosemary & lots of crushed garlic cloves to marinade. Also used only 1/4 c. olive oil. Marinated about 4 hours, would do overnight next time. The kitchen was filled with mouth-watering aromas. Cooked to 145F inside temp. (using oven probe) = perfect meat. I will make this recipe over & over again.

O My Gosh, This pork recipe was awesome. The best ever made. I'm not too keen on pork since one of my pregnancies, but this one...the whole family LOVED it. Definately will make it again.

I tried this for the first time yesterday. My BH and I just loved it. I could hardly wait to tell my married daughters about it. My BH said to never made it any other way. Thanks for a great recipe.

This was the best pork tenderloin I've ever had. I made one modification, since I only had just short of 1/4 c balsamic vinegar I added 1/8 c red wine vinegar. We also cooked it to 160 but that is a personal preference as to how well done we like our meat. We'll make this again for sure.

This was a very tasty recipe. Vinegar was not too strong for us as said in others' reviews. Perfect with "Dilly Cucumbers" and roasted baby red potatoes!

I marinated the pork roast overnight and cooked it on the gas grill on low for about 3 hours. FABULOUS!

I follwed this recipe to the note, and it came out perfect. In agreement with other reviewers, the quality of the balsalmic vinger makes all the difference. DELICIOUS, and looking forward to trying same marinade on chicken.
