Roasted Rosemary Pork Loin is an impressive dinner recipe that is actually very easy to make! Juicy and tender pork loin is crusted in a rosemary and garlic mixture and baked to perfection. Finish by making a little pan gravy and pour it over top each slice and serve it up with some mashed potatoes and roasted veggies.
If you love this recipe you can also make Pork Roast in your Instant Pot, but this recipe calls for a pork butt, not a loin.
Pork LOIN, Not Tenderloin
Yes, there is a difference between a pork loin and a pork tenderloin. A pork loin will look much bigger around and will have a fat cap on one side. The pork tenderloins are generally long and much smaller around.

The other great thing about a pork loin is that it is super economical! On average you will pay around $2-$3 per pound!
Here is what you will need to make this Roasted Rosemary Pork Loin (and a delicious gravy):
- Pork Loin
- White Wine
- Dijon Mustard
- Olive OIl
- Fresh Rosemary
- Fennel Seeds
- Salt & Pepper
- Chicken Stock
You will want to choose a wine that is not sweet. Something like a chardonnay or pinot grigio will work well.
If you don’t want to use wine you can sub chicken stock instead.
If white wine is not something you normally drink you can buy a small carton of wine that holds around 3 cups. Use one cup and then you can FREEZE THE REST (as long as you plan to use it for cooking and not drinking)!!
Tying Your Roast
It is completely optional to tie your pork loin. If you want it to be perfectly round and have a uniform look then tying is a great solution. However if you don’t care what it looks like and just want it to taste great, you can skip this step.
Here is a video on how to tie a roast (the video shows a pork butt, however it is the same tying technique):

If the topping is getting too dark loosely tent some foil over the pork loin.The internal temp should be around 145°. Remove from the oven and let it rest for 15-20 minutes, it will continue to cook as it rests.
- Do not discard the liquid in the pan if you plan on making the gravy below.
- It you tied your pork roast you can remove the string.
- In a skillet over medium heat melt the butter. Sprinkle in the flour and whisk around the pan for 1 minute. Slowly whisk in the liquid from the bottom of the pork loin pan. Add as much chicken broth as you need to get the right consistency in your gravy (anywhere from ½-1 cup).
