The Butterflied Pork Loin Triumph
Mary’s Blue Hour Bistro
Published
At Mary’s Blue Hour Bistro, a lemon-olive pork roulade proved that a little kitchen nerve can lead to an elegant dinner.
A pork loin became the evening’s small triumph at Mary’s Blue Hour Bistro. Though butterflying and rolling the roast initially felt ambitious, the finished lemon-olive roulade arrived in neat slices, its savory spiral clearly visible at the center.
The pork was paired with a kale salad—a smart use of what was already on hand—and an apple-horseradish sauce that brought sweetness, brightness, and a gentle kick to the plate. Under the warm rosy light, the deep-green kale and sliced pork made a handsome contrast on the blue floral china.
A Campari lemon highball, suggested by Mike at the Service Bar, completed the dinner. The night was very warm — we needed a cocktail with seltzer and a giant ice cube! The result was elegant enough to feel like a restaurant special, but it belonged entirely to the Bistro: a confident, delicious reward for trying the more challenging route after all.

# Lemon-Olive Rolled Pork Loin with Apple-Horseradish Sauce
**For 2 diners · 375°F roast · 45-minute countdown, then 10 minutes’ rest**
## Equipment & Before You Start
– Roasting pan or rimmed sheet pan; small skillet if the roasting pan is not stovetop-safe
– Kitchen twine, sharp knife, cutting board, and meat mallet, rolling pin, or heavy small skillet
– Butterfly and gently pound the **1 lb 11 oz pork loin** to an even **½–¾ inch** thickness.
## Ingredients
– 1 pork loin, **1 lb 11 oz**
– **⅓ cup** finely chopped olives, plus chopped olives for finishing
– Zest of **1 lemon**, plus **½ teaspoon** zest for the sauce
– 1 large garlic clove, minced
– **1 teaspoon** dried oregano or rosemary, plus a pinch for the exterior
– Black pepper
– Olive oil
– Salt
– **½ cup** sautéed chopped apples
– **⅓ cup** water
– **1–2 teaspoons** prepared horseradish
– **2 teaspoons** lemon juice
– **2 handfuls** arugula
## Steps
1. Heat the oven to **375°F**. Lightly oil the roasting pan.
2. Mix the **⅓ cup olives**, zest of **1 lemon**, garlic, **1 teaspoon oregano or rosemary**, black pepper, and **1 tablespoon olive oil** into a coarse paste.
3. Spread the filling evenly over the butterflied pork, leaving a **1-inch border**. Roll tightly from a long side and tie at **1½-inch intervals**. Rub the outside with olive oil, salt, pepper, and a pinch of oregano.
4. Set the roast seam-side down in the pan. Start a **45-minute countdown timer** and roast.
5. With **8 minutes remaining**, check the center. The pork should feel springy rather than soft; juices should be clear to pale. A faint blush is fine, but the center should not look raw or glossy.
6. When the timer reaches **0:00**, transfer the pork to a board and rest **10 minutes**.
7. While the pork rests, set the roasting pan over **medium-low heat**, or transfer its drippings to a small skillet. Add the apples and **⅓ cup water**; scrape up the browned bits. Simmer **3–4 minutes**, gently crushing some apple pieces.
8. Stir in the horseradish, lemon juice, **½ teaspoon lemon zest**, and a pinch of black pepper. Simmer **1 minute**, remove from the heat, and stir in **1 tablespoon olive oil**. Taste before salting.
## Hold & Serve
Keep the pork loosely covered while it rests. Keep the sauce warm over very low heat only if needed; stir before serving.
## Watch For
– Keep the olive filling inside the 1-inch border so it does not spill out while rolling.
– Slice only after the full 10-minute rest so the roulade holds its spiral.
– The sauce should be glossy and spoonable, with some apple pieces intact.
## Plate & Present
Lightly dress the arugula with olive oil, lemon juice, salt, and pepper; divide between two plates. Remove the twine and cut the pork into **½-inch rounds**. Fan the slices over the arugula, spoon the apple-horseradish sauce beneath and lightly over the pork, and finish with lemon zest and chopped olives. Wipe the rims and serve both plates together.
