Pecan crusted pork tenderloin is a lean pork tenderloin coated in Dijon mustard, pressed into a seasoned chopped-pecan crust, and baked at 350F until the nuts turn toasty and the meat stays juicy. The mustard glues the crust on and the pecans soak up the pork juices, so every slice gets crunch and flavor.
I’ll be the first to admit I used to think of pecans as a pie thing and nothing else. Then I started cooking with New Mexico pecans (turns out they’re the only nut native to America, and the high desert out there grows some seriously good ones), and the whole idea of a savory pecan crust just clicked.
Chopping the pecans wakes up their flavor, and once they hit the oven they go nutty and toasty in the best way. The real magic is what happens underneath: the pecans soak up the pork juices as it bakes, so the crust tastes like the pork and the pork tastes a little like toasted pecans. It’s a fun way to use pecans that has nothing to do with dessert.
What makes this pecan crusted pork tenderloin so good
Pork tenderloin is the leanest, most tender cut on the pig, so it cooks fast and slices like butter (not to be confused with the chops and cutlets people mix it up with, which my pork cutlet vs pork chop guide sorts out). On its own the cut can read a little plain, which is exactly why the pecan crust earns its keep here.
You get crunch on the outside, juicy meat on the inside, and a sweet, tangy maple Dijon sauce tying it all together. It also feels way fancier than the effort it takes. There is no searing, no brining, and no fussy technique. If you can brush on mustard and roll something in chopped nuts, you can make this, which is why it lands on my December holiday table every year.
Does pork tenderloin need to be seared before baking?
No, this pecan crusted pork tenderloin skips searing entirely. Searing is usually how you build a browned crust, but here the chopped pecans do that job for you, toasting and crisping in the oven. Skipping the pan also means the mustard-and-pecan coating stays put instead of sliding off in a hot skillet.
If you really want extra color, broil the tenderloin for the last minute or two. Watch it closely, because pecans go from toasty to burnt fast.
What internal temperature should pork tenderloin reach?
Pork tenderloin is done at 145F, measured at the thickest part with an instant-read thermometer, then rested for 5 to 10 minutes. The USDA dropped the safe pork temperature to 145F years ago, and at that point the center is juicy with just a hint of blush. The Kitchn has a great breakdown of pork tenderloin cooking methods if you want to nerd out on it.
For a typical 1 pound tenderloin, about 30 minutes at 350F gets you there, but ovens vary, so the thermometer is the one step you don’t want to skip.
How do you keep pork tenderloin from drying out?
The two things that keep pork tenderloin juicy aren’t overcooking it and letting it rest. Because the cut is so lean, every extra few minutes past 145F dries it out, so pull it the moment it hits temperature.
Resting matters just as much. Give it 5 to 10 minutes before you slice so the juices redistribute instead of running out onto the cutting board. The pecan crust helps too, acting like a little jacket that holds moisture in.
Tips for the best pecan crusted pork tenderloin
1. Chop the pecans coarse
You want small pieces, not pecan flour. Pulse them in a food processor and stop while there is still some texture. Coarse pieces give you that crave-worthy crunch and a crust that actually stays crusty.
2. Press the crust on firmly
After you brush the tenderloin with Dijon, roll and press it into the pecan mixture so the nuts really stick. The mustard is your glue, so don’t be shy with it.
3. Use real maple syrup
Real maple syrup makes the sauce. The darker grade has a deeper flavor that stands up to the two mustards. The American Pecan board has more on how versatile pecans are beyond pie if you want some savory pecan inspiration.
4. Make extra sauce
The maple Dijon sauce is good on everything. Double it and keep some in the fridge for sandwiches, roasted veggies, or drizzling over garlic butter salmon later in the week.
What goes well with pecan crusted pork tenderloin?
This pork loves a cozy, slightly sweet side. In the fall and winter I plate it with a big scoop of mac and cheese for full comfort-food mode, or a simple green salad when I want to keep things light. Roasted Brussels sprouts or mashed potatoes round it out into a proper holiday plate. On a busier night when I want the same low-effort payoff, I reach for a hands-off rice cooker coconut curry instead.
Equipment
- food processor
- baking pan
- aluminum foil
- mixing bowls
- measuring spoons
Ingredients
Here’s everything you need. Full measurements are in the recipe card below.
For the pork
- 1 lb pork tenderloin
- 4 tbsp dijon mustard
- 1 cup pecans, finely chopped
- 1 tsp salt
- 1 tsp black pepper
- 1 tsp cayenne
- 1 tbsp fresh thyme
- nonstick cooking spray
For the maple Dijon sauce
- 1/4 cup dijon mustard
- 1/4 cup whole grain mustard
- 1/2 cup maple syrup
Swap notes: no whole grain mustard? Use all Dijon, or a spoonful of yellow mustard for tang. Fresh thyme can become 1 tsp dried in a pinch, and the pecans swap for walnuts if that is what you have on hand.
How to make pecan crusted pork tenderloin
- Preheat your oven to 350F. Line a baking pan with aluminum foil, spray it with nonstick cooking spray, and set it aside.
- Pulse the pecans in a food processor until they are in small, coarse pieces. Stop before they turn pasty.
- In a mixing bowl, combine the chopped pecans, salt, black pepper, cayenne, and thyme. Spread the mix onto a plate.
- Brush the pork tenderloin all over with the 4 tbsp Dijon mustard, then roll and press it into the pecan mixture until coated. Set it on the lined pan.
- Bake for about 30 minutes, until the internal temperature reads 145F. Rest for 5 to 10 minutes.
- Whisk together the Dijon mustard, whole grain mustard, and maple syrup. Slice the pork, drizzle with the sauce, and serve.
Storage and leftovers
Store leftover pecan crusted pork tenderloin in an airtight container in the fridge for up to 4 days. Keep the maple Dijon sauce in a separate container so the crust doesn’t go soggy.
To reheat, warm the slices in a 300F oven or an air fryer for a few minutes so the pecan crust crisps back up. The microwave works in a pinch but softens the crust. Leftovers are also great sliced cold over a salad.

Instructions
- Preheat the oven to 350F. Line a baking pan with aluminum foil, coat it with nonstick cooking spray, and set aside.
- Grind the pecans. Pulse 1 cup pecans in a food processor until they break into small, coarse pieces (stop before they turn to paste).
- Make the crust. In a mixing bowl, stir together the chopped pecans, salt, black pepper, cayenne, and fresh thyme, then spread it out on a plate.
- Coat the pork. Brush the pork tenderloin all over with 4 tbsp dijon mustard, then roll and press it into the pecan mixture. Transfer to the foil-lined pan.
- Bake for about 30 minutes, until a thermometer reads 145F at the thickest part. Rest 5 to 10 minutes before slicing.
- Make the sauce. Whisk the dijon mustard, whole grain mustard, and maple syrup until smooth. Drizzle over the sliced pork and serve.
Notes
- Pull the pork at 145F and let it rest. Carryover heat finishes the cooking while keeping the center juicy.
- Chop the pecans coarse, not fine. Bigger pieces mean more crunch and a sturdier crust.
- No food processor? Add the pecans to a zip-top bag and crush with a rolling pin.
- Adjust the cayenne to taste. A full teaspoon is gentle warmth; use half for kids.
- Make the maple Dijon sauce up to a week ahead and keep it in the fridge.
- Leftover crust mix is great pressed onto chicken or salmon, too.
