Step-by-Step Recipe
- Preparation of the Pork Tenderloin:
- Clean and Trim: Begin by thoroughly cleaning the pork tenderloin. Remove any excess fat or silver skin.
- Slice into Thick Planks: Cut the tenderloin into thick slices—approximately 1 to 1.5 inches thick. These planks will ensure the meat stays juicy during cooking.
- Flatten by Hand: Using your hand, gently pound each slice to achieve an even thickness. This not only tenderizes the meat but also helps it cook uniformly.
- Seasoning: Liberally season each slice with salt and pepper. Simple seasonings allow the natural flavor of the pork to shine.
- Cooking the Pork:
- Heat a generous splash of oil (or a knob of butter for richer flavor) in a heavy skillet over medium-high heat.
- Place the pork slices in the pan and fry them until they develop a beautiful golden-brown crust on each side. This should take about 3-4 minutes per side, depending on thickness.
- Remove the pork from the pan and set aside.
- Sautéing the Onions:
- In the same skillet, add a bit more oil if needed. Throw in a generous amount of sliced onions.
- Sauté the onions until they become soft and slightly caramelized. Don’t rush this step—the slow cooking draws out the sweetness and depth of the onions.
- Bringing It All Together:
- Return the pork tenderloin slices to the skillet with the onions.
- Allow the flavors to meld by stirring everything together over a low heat for an extra minute or two. The onions will coat the tender pork slices with their sweet, savory goodness.
- Pork Tenderloin and Onions Serving:
- Serve the fried pork tenderloin with a generous helping of creamy mashed potatoes. The smooth mashed potatoes are the perfect bed for the richly flavored meat and onions, absorbing every drop of the delicious juices.
Tips and Common Questions
Q: Is this dish really “peasant” food? What makes it so comforting?
A: Yes, this dish is often described as peasant food due to its simple ingredients and rustic preparation methods. It’s high in calories and provides a hearty, satisfying meal that evokes the warmth and practicality of home cooking. It’s a no-frills, honest dish made to nourish and comfort you.
Q: What cuts of pork are best for this recipe?
A: I use pork tenderloin because it’s lean, cooks quickly, and its tenderness is enhanced by the pounding process. However, other similar cuts can work if tenderloin is not available.
Q: I’m not used to pounding meat by hand. Can I do this with a rolling pin?
A: Absolutely! If you don’t want to use your hand, a rolling pin or a meat mallet works just as well to flatten the pork slices for even cooking.
Q: How do I know when the pork is fully cooked?
A: Look for a golden-brown crust on both sides. The meat should be firm to the touch and have an internal temperature of about 145°F (63°C) if you’re using a thermometer. Remember, after resting, the temperature may rise slightly.
Q: Can I substitute the mashed potatoes for something else?
A: Yes, while mashed potatoes are traditional with this recipe, you can also serve the pork and onions over rice, with roasted vegetables, or even on a piece of hearty bread to mop up the flavorful juices.
Q: What type of onions should I use?
A: Yellow onions are great for this recipe because of their natural sweetness and ability to caramelize beautifully. However, you can experiment with red onions for a slightly different flavor profile.
