4 Ingredient Pork Loin Marinade

I’ve never been great at cooking large cuts of meat in the oven. I’m generally a slow cooker kind of girl when it comes to roasts. Fork tender, fall-off-the-bone meat? Yes, please.

But I also enjoy learning new things. Especially when it comes to food.

While I was shopping last week, I saw that boneless pork loins were on sale. I knew I needed to put my big girl pants on and try to actually roast a cut of meat to juicy perfection in the oven.

What You Need to Roast Pork Loin

There were two things I needed to do this. A roasting pan (how did I not have one of these after 18 years of marriage?!) and a oven-safe probe cooking thermometer.

That thermometer? It’s my new favorite kitchen toy. But more on that later.

Easy Pork Loin Marinade

This 4 ingredient pork loin marinade recipe is quick to throw together. It is simply molasses, dijon mustard, white wine vinegar and freshly snipped tarragon. You’ll mix up this easy pork marinade and allow the pork to marinate for at least 3 hours, or even overnight. You want it to soak up all of that savory flavor!

Baking a Pork Loin

When it is time to bake the pork loin, simply place it in a roasting pan and top the pork loin with slices of bacon. This adds flavor and juiciness. Two things I know you want!

Baste the top of the bacon with the molasses marinade.

Next, use a probe thermometer and insert it into the side of the pork roast. The thermometer I use is has a cord that comes out of it and attaches to the display so you can easily read the temperature without opening the oven. My probe thermometer sounds a signal when it reaches 145 degrees. Easy, right?

This pork loin bakes at 325 degrees for about 75-80 minutes. The exact time will depend on the size of your pork loin, which makes the thermometer so important.

Also, use the leftover marinade to baste the pork twice in the first 45 minutes of baking, then throw away the remaining marinade. You’ll want to be sure not to baste the pork loin in the last 30 minutes of baking.

After baking, our pork loin roast turned out moist, tender and oh, so flavorful! It was like a slice of pork steak. My guys loved it and were happy to eat the leftovers for lunches the next few days.

In the end, this 4 ingredient pork loin marinade for baking recipe makes a beautiful presentation.

Serve with a side of Christmas green beans, mashed potatoes and buttery soft rolls.

Give this a try. You may be nervous to roast a pork loin as I was, but you’ve got this. And your family will be impressed!

When cooking in Slow Cooker, do you place the Pork loin in and then just pour all of the marinade over it? cooking for 8-10 hours?

Although I didn’t have time to marinade the meat for long, it still turned out delicious. Great recipe!
