Ingredients

For the Pork & Marinade:

1 pork tenderloin (1.25 – 1.5 lbs / 550-680g), trimmed of silver skin
3 tbsp Dijon mustard (good quality)
2 tbsp olive oil
2 tbsp soy sauce (or tamari)
2 tbsp honey or maple syrup
3-4 garlic cloves, minced
1 tbsp fresh rosemary or thyme, chopped (or 1 tsp dried)
1 tsp black pepper

For the Pan Sauce (Optional but Recommended):

½ cup dry white wine, chicken broth, or water
½ cup chicken broth
1 tbsp cold butter
1 tsp Dijon mustard
Salt & pepper to taste

Instructions

1. Marinate (30 mins – Overnight):

Pat the pork tenderloin very dry with paper towels. Place in a dish or zip-top bag.
Whisk together all marinade ingredients (Dijon, olive oil, soy sauce, honey, garlic, herbs, pepper).
Pour over the pork, turning to coat evenly. Marinate at room temp for 30 minutes, or covered in the fridge for up to 24 hours (the longer, the better the flavor). If refrigerated, let sit at room temp for 30 minutes before roasting.

2. Preheat & Sear:

Preheat oven to 400°F (200°C).
Heat a large oven-proof skillet (cast iron or stainless steel) over medium-high heat. Add 1 tbsp oil.
Remove pork from marinade (let excess drip off, but don’t wipe it clean). Sear on all sides until deeply browned, about 2-3 minutes per side.

3. Roast:

Transfer the entire skillet to the preheated oven.
Roast until the internal temperature reaches 145°F (63°C) at the thickest part, about 15-20 minutes. (Size and oven variances matter—a thermometer is essential!)

4. Rest (Crucial Step):

Transfer pork to a cutting board, tent loosely with foil, and let rest for 10 minutes. This allows juices to redistribute.

5. Make the Pan Sauce (Optional):

While pork rests, place the skillet back over medium heat (handle will be HOT).
Add wine/broth to deglaze, scraping up all the browned bits. Simmer 2-3 minutes to reduce slightly.
Add remaining broth, simmer another 2-3 minutes. Off heat, whisk in cold butter and 1 tsp Dijon until creamy. Season.

6. Serve:

Slice pork into ½-inch thick medallions. Drizzle with any resting juices and the pan sauce. Garnish with fresh herbs.

Key Techniques for Success

Don’t Skip the Sear: Creates a flavorful Maillard reaction crust that seals in juices.
Use a Meat Thermometer: This is non-negotiable. Pork tenderloin is lean and dries out quickly if overcooked. 145°F (63°C) is the safe, juicy target.
Rest is Mandatory: Slicing immediately releases all the precious juices onto the cutting board.
Trim Silver Skin: That tough, silvery membrane won’t break down. Slide a sharp knife under it and slice it off.

Flavor Variations & Additions

Herb-Crusted: After searing, roll the tenderloin in a mix of panko breadcrumbs, chopped parsley, and lemon zest before roasting.
Creamy Mustard Sauce: Substitute heavy cream for half the broth in the pan sauce. Add a splash of whole-grain mustard.
With Apples & Onions: Sear pork, then remove. Sauté 1 sliced onion and 1 sliced apple in the skillet until soft. Place pork on top and roast.
Spicy Honey Glaze: Add 1 tsp sriracha or red pepper flakes to the marinade. Brush with extra honey in the last 5 minutes of roasting.
