Why You'll Love This Ham and Cheese Stuffed Pork Loin

• Guaranteed Juicy Meat: Pork loin is a lean cut that can dry out quickly, but wrapping it around savory ham and melting cheese locks in natural juices and steam-giving you the same succulent tenderness found in our cheesy pork chops and pork Wellington.
• No Leaking Cheese: A simple layering and tucking technique keeps all the gooey, melted cheese sealed inside the roast instead of pooling onto the baking tray.
• Comforting Cordon Bleu Flavor: The combination of seasoned pork, smoky cured ham, and rich bubbling cheese delivers classic comfort food that pairs effortlessly with a fresh Greek village salad or buttery parsley potatoes.
• Stunning Spiral Presentation: Slicing the roast reveals a neat, beautiful swirl that looks impressive on a festive platter or alongside hearty family favorites like sticky honey glazed pork ribs.
• Simple Prep & Budget-Friendly: Uses everyday pantry seasonings and an economical boneless pork loin roast with only 15 to 20 minutes of hands-on prep.

Ingredients for Ham and Cheese Stuffed Pork Loin

1. For the Pork & Aromatic Garlic Baste

• Boneless Pork Loin Roast (1 kg - 1.2 kg / 2.2 - 2.6 lbs): Choose a center-cut boneless pork loin with a thin, uniform fat cap. This lean cut butterflies into a broad, even rectangle that rolls easily around the fillings. As the fat cap gently renders in the oven, it naturally bastes the meat from the outside to prevent drying out. (Be sure not to confuse this with pork tenderloin, which is too thin to butterfly and stuff.)
• Sunflower Oil (3 tablespoon / 45 ml): A neutral, high-smoke-point oil serves as the base of our baste. It carries the garlic and herbs deep into the meat fibers and helps the exterior brown without burning under high heat.
• Soy Sauce (2 tablespoon / 30 ml): Adds deep umami, natural richness, and seasoning. The amino acids in soy sauce also work as a mild tenderizer during the 1-hour resting time.
• Fresh Lemon Juice (1 tablespoon / 15 ml): A touch of gentle citrus acidity cuts through the richness of the pork and melted cheese, balancing the savory glaze and helping tenderize the muscle fibers.
• Honey (1 tablespoon / 20 g): Adds subtle sweetness to balance the garlic and lemon, while encouraging gorgeous exterior caramelization and a glossy, golden finish during the final uncovered roast.
• Fresh Garlic (3-4 cloves, finely minced): Freshly minced garlic releases natural oils that infuse the meat with aromatic warmth. Using fresh cloves gives far deeper, punchier flavor than powdered garlic here.
• Sweet Hungarian Paprika (1 tsp): Adds a warm, earthy sweetness and imparts a vibrant reddish-golden hue to the roasted crust.
• Dried Oregano (1 tsp): Provides a classic herbal aroma that ties the Mediterranean-inspired pepper and cheese filling with the savory pork.
• Fine Sea Salt (1 tsp) & Freshly Ground Black Pepper (½ tsp): Essential baseline seasoning. Using freshly cracked black pepper delivers a sharp, clean bite that balances the sweet honey glaze.

2. For the Vibrant Filling

• Roasted Red Peppers (100 g - 150 g / 1 large pepper): Jarred roasted red peppers (or freshly roasted and peeled peppers) add a sweet, smoky, and juicy layer. Make sure to pat them completely dry with paper towels before layering so excess brine doesn't make the interior soggy.
• Grated Mozzarella (150 g / approx. 1½ cups): Mozzarella melts into a creamy, luscious layer with an irresistible cheese pull without releasing excess oil. You can also swap in mature sharp cheddar if you prefer a bolder, tangier bite.
• Pre-cooked Smoked Ham Slices (150 g / 6-8 slices): Thinly sliced smoked deli ham or prosciutto cotto creates the final savory layer. Placing the ham over the cheese acts as an insulating barrier that locks the melting mozzarella firmly inside the roll as it bakes.

3. For the Seasoned Vegetable Bed

• Potatoes (500 g / approx. 1.1 lbs): Medium starchy or all-rounder potatoes (such as Maris Piper, Russet, or Yukon Gold) hold their shape while soaking up the pan drippings. Slicing them into thick rounds ensures they become tender and buttery on the inside while crisping along the edges.
• White Onion (1 large): Sliced into thick rings and scattered among the potatoes. As the onions roast beneath the covered foil, they caramelize in the pork juices, adding natural sweetness and rich pan sauce aroma to every bite.
• Sunflower Oil (1 tablespoon / 15 ml): Coats the potato rounds and onion rings to ensure the seasonings stick evenly and promote crisp edges.
• Seasoning Blend (1 teaspoon Fine Sea Salt, 1 teaspoon Sweet Paprika, 1 teaspoon Dried Oregano): Ties the flavor profile of the roasted side dish directly to the seasoned pork roast so the entire tray bakes in complete harmony.

Best Cheese Choices for Stuffed Pork Loin

• Swiss / Emmental: The classic Cordon Bleu choice. It has a mild, nutty sweetness and a low-moisture melt that holds its shape neatly when sliced warm.
• Gruyère: The best gourmet option. Deeply savory, earthy, and rich, it melts luxuriously and pairs exceptionally well with pork and Dijon mustard.
• Provolone: A versatile, everyday choice. It is mild, buttery, and slightly tangy, melting into a silky layer without releasing excess oil or moisture.
• Gouda (Mild or Smoked): Creamy, soft, and mellow. Smoked Gouda adds fantastic depth and barbecue-like warmth if you are using unsmoked ham.
• Low-Moisture Mozzarella: Delivers the ultimate gooey cheese pull. Always use firm, deli-style sliced mozzarella rather than fresh mozzarella balls, which release too much liquid and cause soggy meat.

Watch How to Make It: Step-by-Step Video Tutorial

If this is your first time butterflying and rolling a whole pork loin, watching the technique in action makes the process completely foolproof! In the video tutorial below, I walk you through the entire recipe-from making the horizontal cuts and laying down the ham and cheese, to securing the roast with butcher's twine and achieving a perfectly golden crust in the oven.

How to Butterfly, Stuff, and Roll Pork Loin (Step by Step)

1. Mix the Garlic-Herb & Honey Baste

• In a small bowl, whisk together the baste ingredients until well combined:
  • Sunflower oil
  • Soy sauce
  • Fresh lemon juice
  • Minced garlic
  • Honey
  • Sweet paprika
  • Dried oregano
  • Sea salt and freshly ground black pepper

2. Butterfly, Tenderize, and Marinate the Pork

• Trim & Butterfly: Place the pork loin on a cutting board. Holding your knife parallel to the board about 2.5-5 cm (1-2 inches) from the bottom edge, slice horizontally along the length of the meat, stopping about 1.5 cm (½ inch) before the far edge. Open the pork flat like a book.
• Flatten Evenly: Place the butterflied pork between two sheets of cling film. Using a meat mallet or the base of a heavy pan, gently pound the meat to an even thickness of about 1.5-2 cm (½ to ¾ inch).

• Marinate (1 Hour): Brush a generous layer of the prepared baste all over the inside surface of the meat. Roll the loin back into its original shape and let it rest at room temperature for 1 hour to allow the savory juices and garlic to infuse the meat.

3. Prepare the Seasoned Potato and Onion Bed

While the pork marinates, prepare the side dish that roasts directly in the meat juices:

• Cut 500 g (approx. 1.1 lbs) of potatoes into thick rounds and place them in a bowl.

• Slice 1 large white onion into rings and add to the potatoes.

• Drizzle with 1 tablespoon of sunflower oil and toss with 1 teaspoon each of sea salt, sweet paprika, and dried oregano until every slice is evenly coated.

4. Layer the Stuffing

Unroll the marinated pork loin flat on your board with the seasoned side facing up. Layer the fillings across the meat, leaving a 2 cm (1 inch) border around the edges:

• First Layer: Spread the roasted red peppers in a single, vibrant layer across the surface.

• Second Layer: Scatter the grated mozzarella evenly over the peppers (sharp cheddar also works wonderfully here).

• Third Layer: Lay the pre-cooked smoked ham slices across the top to cap the filling.

5. Roll, Tie, and Assemble the Roasting Tray

• Roll Tightly: Starting from the thinner end, roll the pork loin firmly into a neat, tight cylinder so all the filling stays securely inside.
• Truss with Twine: Tie the roast firmly with butcher's twine at regular intervals (about 4 to 5 ties across the length).

• Arrange: Place the rolled pork loin right in the center of a 34 × 24 cm (approx. 13 × 9 inch) roasting pan. Spread the seasoned potatoes and onions evenly all around the meat.
• Baste: Generously brush the top and sides of the pork loin with the prepared baste.

6. Two-Stage Baking for Ultra-Juicy Meat

• Stage 1 (Covered Roast - 45 Minutes): Cover the roasting pan tightly with aluminum foil. Bake in an oven preheated to 190°C (375°F / 170°C fan) for 45 minutes. The foil traps the steam, ensuring the potatoes turn fork-tender while keeping the lean pork incredibly moist.
• Stage 2 (Uncovered Browning - 15-20 Minutes): Remove the foil and brush the pork with another layer of the baste. Return the tray to the oven uncovered for 15 to 20 minutes, until the potatoes are golden and crisp at the edges and a meat thermometer inserted into the pork registers 63°C (145°F).

7. Final Glaze, Rest, and Carve

• The Final Glaze: As soon as the tray comes out of the oven, brush the hot pork loin one last time with the remaining baste for a rich, glossy sheen.
• Rest: Allow the roast to rest in the pan for 10 minutes so the melted mozzarella sets and the savory juices settle back into the meat.
• Carve: Snip away the butcher's twine, slice into thick, beautiful pinwheels, and serve immediately alongside the roasted caramelized potatoes and onions.

Delicious Recipe Variations

• Bacon-Wrapped Pork Loin: For an extra layer of smoky flavor and crispy texture, wrap the outside of the rolled pork loin in strips of streaky bacon before securing it with kitchen twine.
• Sharp Cheddar & Apple: Swap the mozzarella for mature sharp cheddar and add a layer of paper-thin granny smith apple slices alongside the smoked ham for a sweet and tangy balance.
• Spinach & Garlic: Layer raw baby spinach leaves or wilted garlic greens directly beneath the mozzarella for extra color, moisture, and earthy freshness.
• Mushroom & Herb: Add a layer of finely chopped, sautéed garlic-butter mushrooms over the butterflied pork before adding the ham and cheese.
• Spicy Kick: Add a pinch of crushed red pepper flakes or a few finely sliced pickled jalapeños over the roasted red pepper layer for a warm, gentle heat.

What to Serve with Ham and Cheese Stuffed Pork Loin

Because this recipe bakes on a bed of seasoned potatoes and caramelized onions, you already have a complete all-in-one meal coming straight out of the oven! If you want to round out the table for a Sunday roast or family gathering, pair it with light, vibrant sides to balance the savory richness of the melted cheese and pork:

• Crisp, Refreshing Salads: A vibrant Greek yogurt salad with ripe tomatoes and cucumbers, a classic garden salad with lemon-herb vinaigrette, or traditional sun-fermented pickles cuts through the savory meat and melted mozzarella.
• Green Vegetables: Steamed or roasted green beans, tender garlic butter broccoli, or grilled asparagus add fresh color and a light, crisp bite to your plate.
• Crusty Bread: Serve with thick slices of warm crusty bread or homemade potato bread to mop up the savory pan juices, melted cheese bits, and sweet roasted onion drippings left on the tray.

How to Store, Freeze, and Reheat

Storing in the Refrigerator

• Cool Down: Allow the roasted pork and potatoes to cool to room temperature (do not leave out at room temperature for more than 2 hours).
• Container: Transfer the sliced pork loin and roasted vegetables to an airtight glass or plastic container.
• Shelf Life: Keep refrigerated for up to 3 to 4 days.

Freezing Instructions

• How to Freeze: Stuffed pork loin freezes best sliced into individual portions. Wrap each thick slice tightly in plastic wrap, then wrap in a layer of aluminum foil and place in a freezer-safe zip-top bag.
• Freezer Life: Freeze for up to 2 to 3 months.
• Thawing: Thaw overnight in the refrigerator before reheating.

How to Reheat (Without Drying Out the Meat)

Pork loin is lean, so gentle reheating is essential to keep the meat juicy and the cheese creamy:

• Oven Method (Best Result): Place the cold pork slices and potatoes in a baking dish. Drizzle 2 to 3 tablespoons of water, chicken broth, or reserved pan juices over the top to create steam. Cover tightly with aluminum foil and heat in a preheated oven at 160°C (320°F / 140°C fan) for 12 to 15 minutes until warmed through.
• Air Fryer Method (For Crispy Potatoes): Heat the potatoes at 180°C (350°F) for 3 to 4 minutes until crisp. Add the pork slices for the final 1 to 2 minutes just until the cheese begins to melt.
• Microwave Method (Quickest): Place slices on a microwave-safe plate, cover with a damp paper towel or microwave cover, and heat on medium power in 45-second intervals to prevent the pork from becoming rubbery.

Top Tips for the Juiciest Stuffed Pork Loin

• Pat the Roasted Peppers Dry: Jarred roasted peppers carry excess brine and moisture. Press them thoroughly between sheets of kitchen paper before layering; this keeps the inside of the pork roll tight and prevents a soggy filling.
• Don't Skip the 1-Hour Room Temperature Rest: Allowing the marinated pork to sit at room temperature for an hour serves two purposes: the garlic-herb baste penetrates the meat fibers, and taking the chill off the pork ensures the roast cooks evenly all the way to the center without drying out the exterior.
• Tie at Even Intervals: Space your butcher's twine roughly 2.5 to 3 cm (1 inch) apart along the length of the roll. Tying firmly creates uniform thickness, meaning every slice cooks at the exact same rate.
• Use an Instant-Read Meat Thermometer: Pork loin is very lean and dries out quickly if overcooked. Pull the roast out of the oven as soon as the thickest part of the meat registers 63°C (145°F).
• Let It Rest Before Slicing: Give the roast a full 10 minutes to rest before cutting into it. This allows the meat fibers to relax and reabsorb their savory juices, while giving the melted mozzarella time to set slightly so it stays neatly inside each pinwheel slice.
