Author: Kate
Savory and satisfying, this roasted pork shoulder with root veggies and mustard sauce makes a wonderful family dinner. Tender pork pairs perfectly with earthy roasted vegetables while a slightly sweet and tangy marsala-mustard sauce brings everything together.

Ingredients

Instructions

  • Generously season roast on all sides with 2 teaspoons salt and 1/2 teaspoon pepper. Let sit for 30 minutes at room temperature before cooking. Heat oven to 400°F.
  • Combine root vegetables and onions in a large roasting pan or baking dish. One that they can fit in a single layer is good. Drizzle with the 2 tablespoons olive oil, 1 teaspoon salt, 1/4 teaspoon pepper, and rosemary. Toss to combine then spread into an even layer. Nestle the pork roast in the middle.
  • Transfer pan to oven and roast, until an instant-read thermometer inserted in the thickest part reads 170°F, about 40 minutes-1 hour. Remove from oven and cover with foil to rest while you make the sauce.
  • For the sauce, melt the 4 tablespoons of butter in a skillet over medium heat. Whisk in the 1 tablespoon of flour until smooth. Slowly add the 3/4 cup marsala while whisking constantly until a smooth sauce forms. Let simmer until slightly thickened. Sauce will continue to thicken as it cools. Whisk in the 2 tablespoons mustard, 1/2 teaspoon salt, and remaining 1/4 teaspoon black pepper.
  • Place pork roast on a cutting board and slice into thin slices. Serve with vegetables, mustard sauce, and horseradish aioli.

Notes

  1. Add some spice: For a touch of heat, add a pinch of red pepper flakes with the salt and pepper to season the pork and vegetables. 
  2. Leftovers: Leftover pork is fantastic in sandwiches, pasta, or even a simple soup.
  3. Make-ahead: For extra convenience, chop the vegetables the night before to save time when ready to cook.
  4. Serving suggestions: For heartier appetites, serve alongside crusty bread or my homemade focaccia for dipping into those delicious juices.
