Pork Tenderloin Perfection: A Budget-Friendly Delight
My husband often teases me, calling me an "expensive date" because, without fail, I'll choose beef tenderloin if it's on the menu. Yes, I'm worth it! However, with today's grocery prices, splurging on beef tenderloin isn't always practical. So, I turn to my second-favorite, pork tenderloin.
Now, here's the kicker—my husband isn't a big fan of pork tenderloin. Go figure! That all changed when I whipped up this recipe for him. When I announced pork tenderloin for dinner, I got the classic "Oh" response—the one where he's trying to act okay with it but isn't overly thrilled.
Undeterred, I got to cooking, determined to make him a fan of this dish. I might have sweetened the deal with a baked potato (a rare treat in our low-carb household), but hey, it worked!
The verdict? He was genuinely surprised at how much he enjoyed the pork tenderloin. And though he admitted the potato made him happy, he declared this dish worthy of our recipe rotation. Victory dance time! Now, let's talk about the sauce.
This sauce is not only a breeze to make but also pairs wonderfully with chicken. Season up boneless, skinless chicken thighs, cook them in place of pork tenderloin, and you've got a winner. If you're leaning towards chicken breasts, go for smaller or thinner ones for optimal cooking.
Long story short, you can't go wrong with this recipe—budget-friendly, delicious, and a hit with even the toughest critics. Enjoy!

🥘Pork Tenderloin with Creamy Herb Mustard Sauce Ingredients
These are the ingredients necessary to make Pork Tenderloin with Creamy Herb Mustard Sauce.

- Olive or Avocado Oil - Either of these keto-friendly oils will work for this recipe..
A detailed list with measurements and instructions can be found on the printable recipe card at the bottom of the page.
🔪Pork Tenderloin with Creamy Herb Mustard Sauce Instructions
This is a basic breakdown of the steps involved in making Pork Tenderloin with Creamy Herb Mustard Sauce. You will find the full directions in the recipe card at the bottom of the post.
Heat the oil in a large oven-proof skillet over medium-high heat. Sear pork on all sides until it is golden brown.
Return the same skillet to the stove over medium heat and add the heavy cream and mustard.
Add in the powdered sweetener, vanilla powder, salt, and xanthan gum.
Once the sauce begins to simmer, remove it from the heat and stir in salt, pepper, thyme, and parsley.
Helpful Hint: 💡: For a perfectly seared crust on your pork tenderloin, ensure it's thoroughly dry before seasoning. Pat it down with paper towels to remove any excess moisture. This allows the heat to sear the surface, locking in those delicious flavors.
SUBSTITUTIONS
- Pork Tenderloins - If you can't find tenderloins you could use a pork loin but the cooking time will be longer.
- Heavy Cream - For a dairy-free recipe you could use coconut milk instead of heavy cream.
- Fresh Herbs - I highly suggest using fresh herbs but, if needed, you can substitute 1 teaspoon of dried herbs for every tablespoon of the fresh.
📖VARIATIONS
- Herb Medley - Customize the herb blend in the sauce by incorporating your favorite herbs. Rosemary, tarragon, or chives can add distinct and aromatic notes.
- Mushroom Magic - Elevate the dish by sautéing sliced mushrooms in the skillet after searing the pork. Incorporate them into the sauce for a savory mushroom-infused experience.
- Cognac Infusion - For an indulgent touch, deglaze the skillet with a splash of cognac after searing the pork. Allow it to simmer before adding the cream for a rich and flavorful sauce.
🍽Equipment
This is the equipment you will need to make Pork Tenderloin with Creamy Herb Mustard Sauce.
Storage
Storage Instructions: Store any leftover pork tenderloin and sauce in separate airtight containers in the refrigerator. The pork can be stored for up to 3-4 days, and the sauce for 3-5 days.
Freezing Instructions: The pork tenderloin can be frozen for longer storage. Wrap it tightly in plastic wrap or aluminum foil, or place it in a freezer bag, and freeze for up to 2-3 months. The sauce, however, may not freeze well due to the dairy content. The consistency may change.
Reheating:
- Pork Tenderloin: To maintain its tenderness, reheat slices of pork tenderloin in the oven at 325°F (163°C) until warmed through. Cover it with foil to prevent drying.
- Creamy Herb Mustard Sauce: Gently reheat the sauce on the stovetop over low heat, stirring frequently to prevent separation. If it thickens too much, add a splash of water to achieve the desired consistency.
💭Top tip
Don't skip the resting step! Let your beautifully cooked pork tenderloin rest for at least 5 minutes after taking it out of the oven. This allows the juices to redistribute, resulting in a moist and flavorful cut when you slice into it. Patience pays off for a perfect pork experience!
