This is a seared-then-roasted pork tenderloin finished with a blood orange and whole grain mustard glaze. The whole thing takes 45 minutes, and the result is a lean, juicy cut of meat with a sticky, tangy coating that actually tastes like something. It earns a spot in the weeknight rotation and holds up just as well for a dinner party.
What makes this version work
Two things carry this recipe. First, the sear in an oven-safe skillet before roasting builds a crust that holds moisture in — skip it and the tenderloin comes out pale and a little dry. Second, the glaze goes on after the pork comes out of the oven, not before. Blood orange juice and honey both have sugars that scorch fast at roasting temperatures, so applying the glaze at the end means it stays glossy and bright instead of bitter and blackened. Pull the pork at an internal temperature of 145°F (63°C) for whole-muscle tenderloin — this is a safe, USDA-approved temperature for whole cuts of pork, not ground pork — then let it rest a full five minutes before slicing so the juices redistribute. That rest is what keeps every slice moist rather than just the center.
Storage and reheating
Leftover pork tenderloin keeps well in an airtight container in the fridge for up to 3 days. For longer storage, slice it first, wrap tightly, and freeze for up to 2 months. To reheat, place slices in a covered skillet over low heat with a splash of water or orange juice — about 2 to 3 minutes per side. This keeps the meat from drying out, which is the main risk with a lean cut like tenderloin. Avoid the microwave if you can; it heats unevenly and tends to toughen the edges. The glaze will re-melt in the skillet and re-coat the slices on its own.
If something goes sideways
- The glaze is too thin and runs right off the meat: Return it to the pan and simmer for another 2 to 3 minutes. A properly reduced glaze should coat the back of a spoon before you brush it on.
- The pork is cooked through but has no color on the outside: Your skillet wasn’t hot enough before the sear. Next time, let the pan heat for 2 full minutes over medium-high before adding oil, and make sure the surface of the meat is dry — pat it with paper towels before it goes in.
- The glaze tastes flat or one-dimensional: Blood orange juice varies a lot in sweetness depending on the fruit. Taste the glaze before you brush it — a small pinch of salt and a few extra drops of apple cider vinegar usually fixes a dull batch fast.
- The tenderloin is overcooked and dry: Pork tenderloin is thin and cooks faster than you expect. Use an instant-read thermometer and start checking at the 20-minute mark. Skip guessing by time alone — oven temperatures vary enough to matter here.
- The glaze scorched on the skillet during the sear: Any glaze residue left in the pan from basting too early will burn. Keep the glaze off the meat entirely until after roasting, and wipe the skillet if needed before returning it to the stovetop.
Blood Orange Mustard Glaze with Roasted Pork Tenderloin
Ingredients
For the Blood Orange Mustard Glaze
- ½ cup fresh blood orange juice About 2-3 blood oranges, freshly squeezed
- 2 tbsp whole grain mustard Preferably stone-ground for texture
- 2 tbsp honey Raw honey provides better depth of flavor
- 1 tsp apple cider vinegar Enhances balance and brightens the glaze
- ½ tsp salt Use flaky sea salt or kosher salt for best results
- ¼ tsp black pepper Freshly cracked for best aroma
For the Pork Tenderloin
- 1 lb pork tenderloin Trim silver skin for even cooking
- 1 tbsp olive oil For searing the pork
- 1 tsp salt To season the pork
- ½ tsp black pepper Freshly ground for maximum fragrance
Instructions
- Prepare the Blood Orange Mustard Glaze: In a small saucepan over medium heat, combine blood orange juice, whole grain mustard, honey, apple cider vinegar, salt, and black pepper. Stir well and bring to a gentle simmer. Reduce heat and allow the glaze to reduce by about half, around 8-10 minutes, until thickened enough to coat the back of a spoon. Set aside.
- Preheat and Prepare Pork Tenderloin: Preheat oven to 200°C (400°F). Pat the pork tenderloin dry with paper towels and season generously with salt and black pepper.
- Sear the Pork: In a large oven-safe skillet, heat olive oil over medium-high heat. Sear the pork tenderloin on all sides until golden brown, about 2-3 minutes per side.
- Roast in Oven: Transfer the skillet to the preheated oven and roast for 15-18 minutes or until an internal temperature of 63°C (145°F) is reached.
- Glaze the Pork: Remove the pork from the oven and immediately brush with the prepared blood orange mustard glaze. Allow it to rest for 5 minutes before slicing.
- Slice and Serve: Slice the pork into medallions and serve with additional glaze drizzled on top. Garnish with blood orange zest or fresh herbs if desired.
Notes
- For deeper flavor, let the pork sit with a light rub of salt and pepper for 30 minutes before cooking.
- You can substitute chicken breast or firm tofu for a lighter, non-pork option.

Common questions
Can I use regular oranges instead of blood oranges?
Yes, regular navel or cara cara oranges work fine. The glaze will be a little less tart and won’t have the deep color, but the flavor is still good — just add an extra half teaspoon of apple cider vinegar to compensate for the milder acidity.
What should I serve alongside this to make it a full meal?
Roasted root vegetables or a simple green salad are the easiest options since they can go in the oven at the same temperature while the pork roasts. Creamy mashed potatoes also work well because they pick up the extra glaze from the plate.
How do I know when the pork tenderloin is actually done?
Use an instant-read thermometer and pull the pork at 145°F (63°C) internal temperature — this is the USDA safe temperature for whole-muscle pork. Let it rest five minutes before slicing; the temperature will rise a few degrees and the juices will settle.
Can I make the glaze ahead of time?
Yes, the glaze can be made up to 3 days in advance and stored in a sealed jar in the fridge. Warm it gently in a small saucepan over low heat before brushing — it thickens as it cools and needs to be loose enough to spread.
