Brined Pork Tenderloin with Kimchi and Apples

Tender brined pork tenderloin gets seared and roasted alongside tangy kimchi and sweet apple chunks in this Korean-inspired one-skillet dinner. The kimchi brine does double duty, first tenderizing the pork during a quick 2-hour brine, then deglazing the pan to create savory depth. Sweet-tart apples balance the fermented heat while butter adds richness to the pan juices. Perfect for weeknight dinners when you want something special but approachable, this dish bridges Korean flavors with familiar techniques.

Tips
Curve the tenderloin if needed to fit your skillet - it will still cook evenly and brown properly.
Save extra kimchi brine from the jar for marinades or salad dressings - it keeps for weeks refrigerated.
Let the pork rest in the hot skillet to redistribute juices and keep everything warm for serving.

FAQ
Can I use regular cabbage instead of kimchi?
Regular cabbage won't provide the fermented flavor or brine needed for this recipe. Try sauerkraut as the closest substitute, though the flavor profile will be different.
What if I don't have time to brine the pork?
You can skip brining but season generously with salt 30 minutes before cooking. The meat won't be as tender or flavorful as the brined version.
How long will leftovers keep in the refrigerator?
Store covered leftovers up to 3 days. Reheat gently in a 300°F oven to avoid drying out the pork.
