Dijon Pork Loin Roast

We ordered a half a beef this year from a local organic farm, and usually get our chickens from our CSA, but I will admit pork loins are a hard meat to find at our farmers markets. Mostly because they’re a bigger cut, but I have put in several requests hoping I can get some soon. Whenever I head to Costco, I check out the meat department to see if there are any smoking deals and compare to what I’m getting elsewhere. Sure enough the pork loins I found recently were a fantastic deal and great quality.  I came home and dug out my cook books to find this recipe. We’re big fans of dijon mustard around here, and I just knew it would be delicious over some egg noodles.

    What can be used as a substitute for white wine in the Dijon Pork Loin Roast recipe?

    Hi — has anyone made this? The proportions look a little off to me…5 lbs pork roast to 1/4 cup sliced mushrooms? One-half tsp salt and one-half tsp pepper? Was there maybe a typo somewhere? I’m very interested in making this, but it just sounds way off to me.

    • Katie says:

      Hi Ann! The amounts are accurate but you could always add more mushrooms if you want more. I personally wouldn’t add more salt as the soy sauce has salt in it as well. Enjoy!

    Does this need to be thawed before being put into the crockpot? The cook times shown here on this recipe are the same for the frozen directions and regular cooking directions…. Just a little confused. Thanks!

    • Lisa says:

      Yes Keri – you should thaw it completely before putting into crockpot. I have updated directions to reflect.
