Pork Roast with Green Peppercorns

Pork roast with Green Peppercorn Sauce

Pork roasts can be intimidating to cook. The meat itself is lean and if not cooked properly, it’s dry and flavorless. However, all you need to ease that fear are the right tools, quality ingredients, and a good pork roast recipe. If you take the time to gather everything in advance, it makes cooking this stunning roast absolutely foolproof.

This Roasted Pork recipe is from Ina Garten’s Barefoot In Paris cookbook. I like this recipe because the oven does most of the work. The sauce comes together easily at the end and it looks absolutely stunning when served. It elevates an otherwise bland and boring cut of pork to something very decadent.

3 things make this pork roast stand out above the rest.

  1. A good cut of pork, frenched and tied. (This is a good opportunity to visit your butcher.)
  2. A Leave in Oven Thermometer, like the Thermoworks Dot, to ensure the perfect temperature.
  3. Green Peppercorns in brine, pre-ordered online, because they are impossible to find anywhere.

Once you have these 3 things on hand, the rest is a breeze. The result is a roast that is fit for a king. (Or at least some company!)

What makes this pork roast recipe magical is it’s decadent sauce. The sauce is started like a traditional gravy using drippings, flour and stock. Then, to enhance the flavors, two styles of mustards and a unique style of peppercorn are added, taking the sauce to a whole new level.

The brined peppercorns are very different from a regular peppercorn. Whole black peppercorns that you are more familiar with, tend to jump up and bite your pallet, which we expect in certain meals like Steak Au Poive. Instead, these brined peppercorns are soft, and almost melt into the sauce, similar to a caper, but without the intense salt flavor.

The final sauce is rich with an impressive depth of flavor, which pairs nicely with the otherwise simple and lean pork roast.

This Pork Roast recipe is an excellent holiday meal, special occasion dinner, or a Sunday roast for the whole family. I highly recommend serving it with Make Ahead Mashed Potatoes and a good bottle of Burgundy.

My now addiction to Thermoworks thermometers started with the DOT. Having tried over versions of leave-in probe thermometers over the years I quickly learned that they don’t even compare.
