Ingredient Notes

Pork Tenderloin
- Pork – Two fresh pork tenderloins about 1 pound each.
- Seasonings – Salt and pepper to taste.
- Oil – I use olive oil. Other oils such as vegetable, peanut or canola oil can also be used.

Mustard Sauce
- Butter – I always use unsalted butter to control the salt.
- Garlic – Fresh is best, minced. A great flavoring agent.
- Broth – I use organic low sodium chicken broth, to control the sodium level.
- Cream – Use high fat cream greater than 30% but you can use a lower fat content, if desired.
- Mustard – Both a dry and wet mustard is used. For a wet mustard, I prefer using Dijon.
- Herbs – Dried thyme and fresh parsley for garnish.
- Seasonings – Salt and pepper to taste.
How To Make Pork Tenderloin With Mustard Sauce

- Preheat the Oven: Preheat the oven to 400°F.
- Season the Meat: Season the pork chops with the 1 tsp salt and pepper evenly all around.
- Sear and Cook the Meat: Heat the olive oil in a large oven-safe skillet and sear the pork tenderloins on all sides, about 2 to 3 minutes per side. Transfer the skillet to the preheated oven and cook for 18-20 minutes or until a thermometer reads an internal temperature of 145°F. Transfer the pork tenderloins to a cutting board and let it rest for 10 minutes.
- Make the Sauce: In the same skillet, melt the butter over medium heat. Add the garlic and cook for 30 seconds until aromatic. To the skillet, add the chicken broth, heavy cream, dry mustard powder, regular mustard, dried thyme, parsley, salt and pepper. Stir everything together scraping the browned bits from the bottom of the skillet, turn the heat down to a simmer and cook for 8 to 10 minutes until sauce thickens a bit.
- Finish and Serve: Slice the pork and serve with mustard sauce over mashed potatoes.

Fridge
Store the pork tenderloin in an airtight contain for 3 to 4 days in the refrigerator.Â
Freezer
Pork tenderloin freezes well, however, because the sauce contains cream, the texture may not be as good as fresh. Another option is to freeze the pork and the sauce separately, but again, the sauce texture may not be as good. Freeze both the pork tenderloin and the sauce in an airtight freezer bag or container for up to 1-2 months. If freezing separately, the pork can be frozen longer, up to 4 months.
