Ingredients

• 1 piece (about 1 lb) pork tenderloin
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 1 medium (finely chopped) shallot
• 0.5 cup dry white wine
• 0.5 cup chicken stock
• 0.5 cup heavy cream
• 2 tablespoons grainy mustard
• 1 tablespoon (chopped, optional for garnish) fresh parsley

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Pat the pork tenderloin dry with paper towels, then season all over with 1 teaspoon of salt and 1/2 teaspoon of black pepper.

Step 3

In an oven-safe skillet, heat 2 tablespoons of olive oil over medium-high heat.

Step 4

Sear the pork tenderloin on all sides for about 2 minutes per side, until a golden crust forms.

Step 5

Transfer the skillet to the preheated oven and roast the pork for 15-20 minutes, or until the internal temperature reaches 145°F (63°C). Remove the pork from the skillet and set it aside to rest, tented with foil.

Step 6

In the same skillet, melt 2 tablespoons of unsalted butter over medium heat.

Step 7

Add the chopped shallot and sauté for 2-3 minutes until softened and fragrant.

Step 8

Deglaze the pan by adding 1/2 cup of dry white wine, scraping the bottom to loosen any browned bits. Simmer for 2 minutes until slightly reduced.

Step 9

Stir in 1/2 cup of chicken stock and 1/2 cup of heavy cream, and let it simmer for another 2-3 minutes.

Step 10

Whisk in 2 tablespoons of grainy mustard, and cook for an additional minute to combine and thicken the sauce slightly.

Step 11

Slice the rested pork tenderloin into medallions and serve topped with the grainy mustard sauce.

Step 12

Garnish with chopped parsley if desired and serve immediately.
