Prep time: 5 minutes
Cook time: 20–25 minutes
Rest time: 5–10 minutes
Servings: 3–4
Difficulty: Easy

Ingredients

• 1 (1–1½ lb) pork tenderloin

• 2 tablespoons Dijon mustard

• 3–4 cloves garlic, minced

• 1 tablespoon dried Italian seasoning or rosemary

• Salt and black pepper, to taste

Instructions

1. Preheat
Preheat your oven to 400°F (200°C). Line a baking sheet or roasting pan with parchment paper or foil for easy cleanup.

2. Season the pork
Pat the pork tenderloin dry with paper towels. Season lightly with salt and pepper on all sides.

3. Make the rub
In a small bowl, combine the Dijon mustard, minced garlic, and dried herbs. Spread the mixture evenly over the entire surface of the pork.

4. Roast
Place the tenderloin on the prepared pan and roast for 20–25 minutes. For best results, use a meat thermometer—the pork is done when it reaches an internal temperature of 145°F (63°C).

5. Rest and serve
Remove from the oven, tent loosely with foil, and let rest for 5–10 minutes before slicing. This step locks in the juices. Slice and serve.

Why This Recipe Works

• Low in points: Dijon mustard acts as a binder and adds tang without oil or sugar.

• High protein: Pork tenderloin is as lean as skinless chicken breast, offering a flavorful alternative.

• Simple & versatile: Perfect on its own, sliced for sandwiches, or served alongside roasted vegetables, rice, or a fresh salad.

Tips & Variations

• Make extra: This recipe doubles or triples easily for a crowd. Leftovers are delicious cold or gently reheated.

• Herb swap: Try thyme, oregano, or a blend of fresh herbs if available.

• Add a glaze: For a touch of sweetness, brush with a little sugar-free maple syrup or balsamic glaze during the last 5 minutes of roasting.

• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.

Enjoy this effortless, flavor-packed pork tenderloin as a go-to weeknight staple.
