Smoked Dijon Pork Tenderloin is a rich, flavorful dish that pairs tender pork with a creamy Dijon and caramelized onion sauce. Cooked on a pellet grill for a touch of wood-fired flavor, this recipe feels special enough for guests yet is straightforward to prepare at home. Serve it over garlic mashed potatoes, buttered noodles, or rice to capture every drop of the savory gravy.
Smoked Dijon Pork Tenderloin Recipe
Pork tenderloin is an excellent choice for an easy, protein-rich dinner: it cooks quickly, is naturally tender, and is often budget-friendly. This dish is inspired by a long-standing favorite—an old slow-cooker version made with pork chops—and updated here with a whole pork tenderloin finished on a pellet grill to introduce a mild smoky depth. The star is the onion and Dijon cream sauce: caramelized onions provide sweet, savory body while mustard and a splash of vinegar add lively tang.
The sauce becomes luxuriously silky after finishing with cream, making it ideal spooned over starches like mashed potatoes or wide noodles. It’s a reliably impressive recipe that’s perfect for weeknights when you want something a little elevated without fuss.
Don’t have a smoker or pellet grill?
No problem. You can easily make this dish in the oven. Start by searing the seasoned pork in a hot skillet on the stove to build color, then transfer the pork to a baking dish, pour the prepared onion mixture over it, and finish in a 325°F oven until the internal temperature reaches the target range. The result will still be flavorful and satisfying.

How To Make This Recipe
Below is a clear overview of the process so you know what to expect. Follow the full instructions for timing and temperature to ensure a perfect result.
- Preheat and season: Heat your pellet grill (or oven) and generously season the pork with salt, pepper and garlic powder (or an SPG blend).
- Caramelize onions: Sauté sliced onions in butter over medium heat until deeply golden and soft. Add a bit of flour, then deglaze with white wine and add chicken stock, cider vinegar, cayenne, and Dijon. Simmer until slightly reduced and thickened.
- Sear and smoke: Sear the tenderloin on the grill for a few minutes per side to develop color. Transfer to a grill-safe pan and spoon the onion mixture over the meat.
- Finish cooking: Lower grill temperature and continue cooking until the internal temperature registers about 135–140°F for a juicy medium finish. If using an oven, bake at 325°F until temperature is reached.
- Rest and finish the sauce: Tent the pork and let it rest at least 10 minutes. Whisk heavy cream into the pan sauce and adjust seasoning. Slice the tenderloin into medallions and return them briefly to the sauce before serving.
Recipe Card
Yield: Serves 4 | Prep Time: 20 minutes | Cook Time: 40 minutes | Total Time: 1 hour
Ingredients
- 2 pound pork tenderloin
- 1 tablespoon salt, pepper and garlic blend (or 1 tsp salt, 1/2 tsp pepper, 1/2 tsp garlic powder)
- 4 tablespoons salted butter
- 3 cups sweet onions, thinly sliced
- 3 tablespoons all-purpose flour
- 1½ cups dry white wine
- 1 cup chicken stock
- 2 tablespoons cider vinegar
- ½ teaspoon cayenne pepper (adjust to taste)
- 2 tablespoons Dijon mustard
- ½ cup heavy cream
Instructions
- Preheat your pellet grill to 375°F (or preheat the oven to 375°F if finishing indoors).
- Season the pork tenderloin with the salt/pepper/garlic blend. If you don’t have a premade blend, a simple mix of salt, black pepper and garlic powder works well.
- In a large skillet, melt the butter over medium heat. Add the sliced onions and cook, stirring frequently, until they begin to brown. Reduce the heat to medium-low and continue to caramelize the onions until soft and deeply golden.
- Sprinkle the flour over the onions and stir to combine. Add the white wine, chicken stock, cider vinegar, cayenne and Dijon mustard. Stir well, bring to a gentle simmer and let the sauce reduce and thicken slightly over low heat.
- Place the seasoned pork on the preheated grill and sear about 5 minutes per side to develop color. The pork should not be fully cooked at this point.
- Transfer the pork to a grill-safe baking dish and pour the thickened onion mixture over the top, allowing some sauce to spill around the sides.
- Reduce the grill temperature to 325°F and return the pan to the grill. Cook for about 20–25 minutes, or until the internal temperature reaches 135–140°F for medium doneness.
- Remove the pork from the sauce and tent loosely with foil. Let it rest at least 10 minutes.
- While the meat rests, whisk the heavy cream into the sauce in the pan and warm gently until the sauce is silky and cohesive. Taste and adjust seasoning if necessary.
- Slice the rested tenderloin into medallions, return the slices to the sauce to coat, and serve immediately over mashed potatoes, buttered noodles, or rice.
