THE BEST PORK TENDERLOIN 
I've been told many times this is the best pork loin ever! The mayonnaise melts into the soup mix and makes an incredibly soft crust that you won't believe. It's so easy and will impress your friends.

2 pork tenderloins
1 jar Best Foods mayonnaise
1 box (2 envelopes) Lipton's Dry Onion Soup Mix
1 (9x13-inch) baking pan or dish

Set oven to 375°F.

Pat tenderloins dry with a paper towel and place in 9x13-inch baking dish or pan. Coat both loins evenly with the mayonnaise about 1/8 of an inch thick around entire loin.

Empty the envelopes of soup mix on cutting board and use rolling pin or back of big spoon to crush up the soup mix as best you can. Evenly sprinkle on top of mayonnaise around entire outside of both loins.

Bake, uncovered, for about 35 to 45 minutes or until internal temperature is about 160°F or according to USDA standards for cooking pork.

Recipe may be halved for a smaller family. This feeds 5 to 6 people as-is.

I had purchased a pork tenderloin because it was on sale and I had no idea how to cook it. I found this recipe online and decided to try it! The only mayonnaise I had on hand was Hellmann's. Let me say, this was the best pork I have ever made. It was so juicy, tender, and full of flavor... and super easy to prepare! Thanks for the recipe.

A KEEPER FOREVER!!!! Every guest for dinner is asking for the recipe and the "thanks" keeps coming. This was the easiest and best ever! From the oven I let it rest for about 15 min. (foil covered). It was so tender and juicy.
THANK YOU!!

How big a jar of mayo? Or how many cups?

Hi Stella,

Just use enough of the mayonnaise to coat. You may not need to use the entire jar. I would recommend a 16 oz jar; you may have some leftover depending upon the size of the pork loins used.

We loved this recipe so much, my 3 kids and I kept coming back to the kitchen after we were finished with dinner and picked at the pork and the yummy crust until it was gone!! We have never been big meat eaters so that should tell you something!

I generally do not like (or eat) pork tenderloin, but this recipe is great. Everyone at our new years day dinner loved it! I actually loved it. Will do it again (thought i'd never say that about pork). Thanks.

WOW.. That is what my husband said and my four young children.. I added cooked egg noodles to the pan about five minutes before it was done. Talk about great! I will use this again and again.

I cooked pork tenderloin for the very first time using this recipe and it was great. I served it with fingerling potatoes and it's now the only thing my fiance wants to eat. I'll be making it for him twice in the span of 5 days!

Very good ! I wrapped mine in bacon and I think that was the perfect finishing touch.

 David (British Columbia) says:
To be totally honest, it tasted like pork tenderloin ... Coated in onion soup mix !!! I used a 1/2 package to one large loin, making sure I got all parts of the mix evenly, no too heavy on the onion or soup part. It still simply tasted like soup mix, heavy on the salt. And yes, I crushed it, and actually sprinkled as apposed to roll. The mayonnaise part is neat, I will do that again, and coat with a better topping. The mayo, both sealed and coated very nicely. We did not enjoy this recipe, as is.

I LOVED this recipe! I like meat, but have to have it tender and tasty... this is a winner! My husband and kids thought the crust was too salty, but it was perfect for me. I will share this recipe with family/friends and definitely cook it again... Thank you!

I also found that to cut cooking time sear the tenderloin first, and also i added horseradish to taste and give it a little kick (but not to much of a kick) and use Italian bread crumbs, it will melt in your mouth =) =)

That's a great tip Lynn! Searing the tenderloin first is a great way to add flavor while also cutting down on cook time. And I love that you added horseradish and Italian bread crumbs, what a delicious combination! Thank you for sharing your tips with us!
