If you love blackened fish or chicken, but haven’t tried blackening pork yet, this is THE best recipe to try out this delicious cajun inspired cooking technique for a juicy, never dry pork tenderloin and vegetables all on one sheetpan!

What is Blackening?

Blackening is a really simple technique to brings tons of cajun flavor fast – typically when blackening a dish, the food is dipped in melted butter and then dredged in a mixture of herbs and spices, usually some combination of thyme, oregano, chili pepper, peppercorns, salt, garlic powder and onion powder.

You can buy or make your own blackening spices – and use them on fish, beef, chicken – and this amazingly delicious pork tenderloin!

Since blackening spices are usually gluten free and don’t contain sugar, they work in just about any diet plan (you might want to check the sodium levels if you’re on a low sodium diet, as blackening spices can contain a lot of extra sodium.)

How To Keep Pork Tenderloin From Drying Out

Since pork tenderloin has little fat, it can become tough very quickly when overcooked – I’m providing my best tips and tricks to keep your blackened pork tenderloin moist below:

Marinate Pork Tenderloin

Marinating or brining blackened pork tenderloin before cooking will always help to soften the pork tenderloin and keep it from drying out.

I love using a bottle of simple Italian Dressing or a cup of olive oil with some lemon juice, salt, and pepper for an easy overnight pork tenderloin marinade.

I’m not calling for marinade in this specific recipe because we’re wrapping it in foil and slathering it in butter so it cooks in its own sort of gravy (I designed this recipe to taste great even if you didn’t remember to marinate) – but if you’d like to kick your pork tenderloin up a bit, marinating is always a great idea!

Sear Before Baking

Searing your pork before baking it not only helps to lock in the pork’s juices – it tastes great and gives you a perfect crunchy texture. This is especially important for baked blackened pork, since the crunchy, blackened crust is a crucial part of this recipe’s flavor!

Look for “Pre-Seasoned” Pork Tenderloins

Pre-seasoned pork tenderloins from your grocer are often dry-brined with salt beforehand, so it doesn’t need additional marinating or brining.

Don’t Overcook. 

Pork tenderloin dries out very quickly when overcooked. I often pull my pork tenderloin at 140-145 degrees and tent it with foil to continue carryover cooking as it rests for about 10 minutes before serving.
