## How to Make Stuffed Pork Loin?

First open the loin crosswise like a book, without cutting through, to get a flat surface for the filling. Pound it to an even thickness so it rolls neatly.

## Oven Baked Stuffed Pork Loin Recipe

**Preparation:** 20 minutes
**Cooking:** 40 minutes
**Servings:** 4

### Ingredients

- 1 kg (2.2 lb) of pork loin
- 250 ml (1 cup) of white wine
- 250 ml (1 cup) of vegetable broth
- 200 g (7 oz) of mushrooms
- 10 spinach leaves
- 4 tablespoons of breadcrumbs
- 2 spring onions, finely chopped
- 2 tablespoons of parsley
- Olive oil
- Fine salt
- Black pepper
- Mustard

### Instructions

1. Lay the butterflied loin on a clean board, cover with plastic wrap, and pound gently with a rolling pin or bottle to thin it. Remove the wrap, brush with a thin layer of mustard, season with salt and pepper, and cover with the washed spinach leaves.

1. In a large skillet, heat a splash of oil over high heat and sauté the spring onions for a few minutes, stirring with a wooden spoon. Add the mushrooms and cook 3 more minutes, season, and stir in the parsley and breadcrumbs.

1. Spread the filling over the spinach, roll the meat up tightly, and tie it with kitchen twine about every 2 cm (¾ inch). In a large pot, heat a splash of olive oil over high heat.

1. Sear the tied loin on all sides, about 2 minutes per side, transfer to a baking dish, add the wine and vegetable broth, cover with foil, and bake in an oven preheated to 180°C (356°F) for about 30 minutes. Serve sliced, ideally with freshly sautéed vegetables.

## Additional Tips

### Sautéed vegetables

Toss broccoli florets or asparagus tips, 2 sliced carrots, and 1 red bell pepper in strips in a hot pan with olive oil for 5 to 8 minutes, season, and serve alongside.

### Check the center

Pork loin is done at 63°C (145°F) in the center; rest it 5 minutes before slicing.

### Tie firmly

Tight twine every 2 cm keeps the roll round and the filling inside.

### Use the juices

Spoon the wine and broth from the pan over the slices.

| Original ingredient | Substitute | Ratio | Flavor note |
| --- | --- | --- | --- |
| Mushrooms | Chopped prunes | 200 g | Sweet, festive |
| Mushrooms | Crispy bacon | 150 g | Smoky |
| Spinach | Chard | 10 leaves | Earthier |
| White wine | More broth | 250 ml | No alcohol |

## Frequently Asked Questions (FAQs)

### 1. What does the mustard do?

The thin layer of mustard helps the spinach and filling stick to the meat and adds a tangy note that lifts the pork.

### 2. Why sear the loin before baking?

Searing over high heat creates a golden crust through the Maillard reaction, which adds flavor and color to the roast and the pan juices.

### 3. Can I replace the mushrooms in the filling?

Yes. Use other mushrooms, chopped prunes, crispy bacon, or a mix of bell peppers and caramelized onion. The filling should be tasty and not too wet.

## Did You Know?

A good pork loin is cylindrical, smooth, and pinkish, with plenty of lean meat and a moderate amount of fat, which adds flavor and juiciness.
