Memories of Comfort in a Savory Sandwich
Growing up in an Eastern European household, we often enjoyed rustic dishes prepared with braised cabbage or sauerkraut, paired with some sort of savory and saucy meat.
A meal like this is a kind of classic “peasant food”, and it’s one of my favorite styles of food to this day, one that I still gravitate towards when I’m longing to enjoy a meal that celebrates my European heritage.
Nothing was more delicious to us than dipping fresh bread into that savory leftover sauce from the meat with those little bits of onion in it. Those aromatic flavors coated the palette with such richness as the soft-yet-slightly-chewy bread simply melted away…
To this day, I still love to dip my bread into a sauce like that!
It got me thinking that perhaps a delicious and hearty sandwich could be made with some of the same flavors to bring back those memories, and so a recipe for a pork tenderloin sandwich sounded like just the ticket.
Roasted pork tenderloin, all peppery and crusty on the outside and tender and juicy on the inside, is a perfect partner for sweet-n-savory beer-braised onions and tangy sauerkraut with it’s crispy bite.
These ingredients stuffed in a soft crusty roll, along with melted Swiss cheese, make for a succulent pork tenderloin sandwich that’s simply steeped in love and some “old-world” flavor.
How to Make a Pork Tenderloin Sandwich
Because roasted pork tenderloin is a naturally tender and juicy cut of meat, all it needs is a liberal rub of seasoning to give it a little “boost”.
I like to rub pork tenderloin with a bit of olive oil, some salt and pepper, a pinch of caraway seeds, a little smear of mustard, plus a sprinkle of dried herbs to help create a savory crust.
Then, I simply roast the tenderloin in a hot oven until golden-brown before thinly slicing it, so it can be easily layered with the other mouthwatering ingredients in a sandwich.
Here’s a peek at my pork tenderloin sandwich recipe: (or just jump to the full recipe…)
- I season my pork tenderloin, then roast it for roughly 40 to 45 minutes, or until the internal temp reads 155°.
- While the pork roasts away, I braise my sliced onions in a good beer (one that I’d drink along with the sandwich), until sweet and caramelized.
- To assemble my sandwich, I slice the pork tenderloin thinly, add a layer of it to the bottom half of my prepared crusty roll, then top with a slice of Swiss cheese.
- I broil the sandwich, just until the cheese is melted, then spoon over some of the braised onions and a sprinkle of cool sauerkraut, cover with the top half of my roll (smeared with extra mustard, of course!), and serve hot.
Tips & Tidbits for my Pork Tenderloin Sandwich:
- Caraway seeds in the spice mix: If you can’t find ground caraway seeds, you can get whole ones (which is what I do), and grind them yourself in a spice grinder or pestle and mortar. Or, you can leave them out all together, if you prefer.
- Use a digital thermometer to get the proper temp: It is recommended for pork to have an internal temperature of between 145° (for medium rare) to 160° (for medium). I like to remove mine from the oven around 150-155°, and allow the pork to rest for 10 minutes before slicing (the temp continues to go up slightly as the meat rests). I recommend using a digital thermometer for accuracy, rather than go solely based on time.
- Choose a good beer to braise your onions: I love a good Czech Pilsner, so I used a cup for my beer-braised onions. But feel free to use whatever type of beer you like, something you’d drink along with your sandwich!
- Rinse your kraut to cut the “sharpness”: Since sauerkraut can be quite sharp and tangy, you can give it quick rinse under running water to cut that sharpness a bit(pat dry with a paper towel), if you prefer. Otherwise, if you like some extra tang, use the kraut straight out of the package!
