1. Directions
2. Pat the pork tenderloin dry with paper towels. Rub the melted coconut oil all over the pork, then season generously with chopped rosemary, salt, and pepper.

Pro Tips
- Sear the tenderloin for 2-3 minutes per side over medium-high heat until a deep golden crust forms — that browned fond is where most of the flavor comes from.
- Cook the pork to an internal temperature of 145°F / 63°C and pull it right there; tenderloin goes dry fast if it drifts past that mark.
- Let the meat rest a full 5 minutes before slicing so the juices stay in the pork instead of running out onto the cutting board.
- Give the cauliflower a minute to brown in the skillet before lowering the heat and covering — that extra color is worth the sixty seconds of patience.
- Deglaze the skillet with a splash of white wine or chicken broth after searing for an easy pan sauce; leftovers keep 3-4 days in the fridge and reheat best gently so the pork doesn't toughen.
Frequently Asked Questions
What internal temperature should pork tenderloin be cooked to?
Pull it at 145°F / 63°C and let it rest 5 minutes — residual heat finishes the job and keeps every slice juicy.
Is this rosemary pork tenderloin keto-friendly?
Yes — each of the four servings has about 5g of carbohydrates, along with 38g of protein and 11g of fat, and the whole meal cooks in one skillet.
Can I make this dish ahead of time?
It's best cooked fresh since tenderloin dries out on reheating, but you can chop the cauliflower and prep the rosemary ahead. Leftovers keep 3-4 days and are lovely sliced cold or very gently warmed.
Can I freeze cooked rosemary pork tenderloin?
Yes — slice it first, freeze it in airtight containers for up to 2 months, and thaw overnight in the fridge before reheating gently with a spoonful of broth to keep it moist.
