Ingredients You’ll Need
Here’s the short and friendly shopping list:
For the Pork Tenderloin
- 1 pork tenderloin (about 1–1.5 lbs)
- 2 tablespoons olive oil
- 3 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon paprika
- 1 teaspoon dried thyme or rosemary
- 1 tablespoon butter
For the Mashed Potatoes
- 4 large potatoes (Yukon Gold or Russet work best)
- 3 tablespoons butter
- ½ cup milk (or cream if you’re feeling fancy)
- Salt to taste
- Black pepper to taste
Optional: chopped parsley for garnish
Optional but highly recommended: A drizzle of pan juices over the pork when serving. Trust me on this one.
Step-by-Step Instructions
Prep the Potatoes Peel and chop the potatoes into evenly sized chunks. Toss them into a pot of salted water and bring it to a boil. Cook for about 15–20 minutes until they’re fork-tender. If the fork slides in easily, they’re ready.
Season the Pork Pat the pork tenderloin dry with paper towels (this helps it sear better). Rub it with olive oil, then coat it with salt, pepper, paprika, garlic, and thyme. Make sure the seasoning covers all sides.
Sear the Pork Heat a skillet over medium-high heat and add a little oil. Place the pork tenderloin in the pan and sear each side for about 2–3 minutes until golden brown. This step locks in flavour and gives it that delicious crust.
Finish in the Oven Transfer the seared pork to a baking dish or oven-safe pan. Bake at 400°F (200°C) for about 15–20 minutes, or until the internal temperature reaches 145°F (63°C). Important tip: Let the pork rest for 5 minutes before slicing. This keeps it juicy.
Mash the Potatoes Drain the cooked potatoes and return them to the pot. Add butter and milk, then mash until smooth and creamy. Season with salt and pepper to taste. Pro tip: Warm milk makes mashed potatoes smoother. Cold milk = sad potatoes.
Serve It Up Slice the pork tenderloin into medallions. Plate it alongside the mashed potatoes and drizzle with the flavourful pan juices. Sprinkle parsley if you want to feel extra professional. Boom Dinner is served.
Common Mistakes to Avoid
Even easy recipes have a few traps. Let’s dodge them.
- Skipping the sear
This step builds flavour. Without it, the pork will taste… fine. But we want amazing, not fine. - Overcooking the pork
Pork tenderloin cooks fast. Use a thermometer if possible. 145°F is perfect. - Not letting the meat rest
Cutting immediately after cooking releases all the juices. Give it 5 minutes—patience pays off. - Watery mashed potatoes
Too much milk = potato soup. Add liquid gradually. - Forgetting salt in the potato water
Unsalted potatoes taste bland. Salt the water like pasta.
Alternatives & Substitutions
Cooking should be flexible. If you’re missing something, don’t panic.
- No pork tenderloin?
Use pork loin or chicken breast instead. Cooking time may change slightly. - No milk for the potatoes?
Use cream, half-and-half, or even sour cream for extra richness. - Want more flavour?
Add roasted garlic to the mashed potatoes. IMO, garlic makes everything better. - Trying to be healthier?
Swap mashed potatoes for mashed cauliflower. It’s surprisingly good. - Need dairy-free?
Use olive oil or vegan butter and almond milk.
Cooking is part science, part “let’s see what happens.” Have fun with it.
