Pork tenderloin, heavy cream, grated parmesan cheese, salted butter and Dijon mustard combine together to make Keto pork tenderloin with creamy mustard, a beloved pork dish of low-carb eaters and pork lovers.

Ingredients

• 1 pork tenderloin

• 1 tablespoon olive oil

• 1 tablespoon dijon mustard

• Creamy Mustard Sauce:

• 1/2 cup heavy whipping cream

• 2 tablespoons salted butter

• 1/4 cup finely grated parmesan cheese

Directions

• Prepare: Preheat oven to 375 F. Pat pork tenderloin dry with paper towels. If unseasoned, season all sides with salt and pepper.
• Sear & Roast: Heat oven-safe pan over medium-high heat. Coat bottom of pan with olive oil. Add pork and cook until browned on one side, about 4 minutes. Flip pork in pan, and transfer to oven. Bake at 375 F until pork is browned and cooked through, about 25 minutes (thermometer inserted in center should read at least 145 F). Transfer pork to plate to rest; do not slice yet.
• Make Sauce: Add all sauce ingredients to now-empty pan over medium heat. Use sturdy wooden utensil to loosen any browned bits stuck to pan. Stir until cheese and butter are melted. Let sauce simmer until thickened, about 5 minutes.

Keto Pork Tenderloin with Creamy Mustard – Tips & Notes

Keto & low-carb friendly:

• This dish is rich in fats and protein while keeping carbs very low, making it ideal for keto and low-carb diets.
• Pairing with mashed cauliflower, roasted vegetables, or keto-friendly greens enhances the meal without adding significant carbs.

Preparation tips:

• Pat the pork dry before searing to ensure a nice golden crust. Moisture on the surface will steam the meat instead of searing it.
• Season pork generously with salt and pepper to bring out its natural flavors.

Cooking tips:

• Sear the pork over medium-high heat for about 4 minutes per side to create a caramelized crust before roasting.
• Use a meat thermometer to check doneness; the internal temperature should reach at least 145°F (63°C). Let the pork rest 5–10 minutes before slicing to retain juices.

Sauce tips:

• After removing the pork, use the same pan to make the creamy mustard sauce. The browned bits left in the pan (fond) add depth and flavor.
• Stir continuously as the butter, cream, and parmesan melt to prevent burning.
• Simmer until thickened to coat the pork nicely.

Serving suggestions:

• Slice the tenderloin thinly and drizzle with the creamy mustard sauce.
• Serve alongside keto-friendly sides like mashed cauliflower, cheesy asparagus, or roasted artichokes for a complete low-carb meal.

Optional additions:

• Add fresh thyme or rosemary to the pan while roasting for aromatic flavor.
• A splash of white wine or chicken broth in the sauce can enhance complexity.

This keto pork tenderloin with creamy mustard is elegant enough for dinner guests yet simple for a weeknight meal.
