Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 2 hours 30 minutes
• Total Time: 3 hours
• Servings: 6-8
• Dietary Type: Not specified

Ingredients

• 4 lbs pork loin
• 1 tablespoon olive oil
• 1 teaspoon thyme leaves
• 1/4 cup butter
• 4 large onions, chopped (Vidalia or Texas Sweet preferred, about 4 cups total)
• 1/4 cup flour
• 1 teaspoon chicken base (bouillon works fine)
• 1/4 teaspoon ground nutmeg
• 1 cup water
• 1 tablespoon cornstarch, mixed with 1 tablespoon water
• 1 tablespoon lemon juice
• Salt and pepper to taste

Equipment Needed

• Roasting pan
• Medium frying pan
• Sharp knife
• Measuring cups and spoons
• Meat thermometer

Instructions

1. Begin by preheating your oven to 325°F (160°C). This lower temperature will ensure the pork roasts evenly and remains juicy.

2. Prepare the pork loin by rubbing it generously with olive oil. Season liberally with salt, pepper, and thyme leaves. Don’t be shy with the seasoning; it’s crucial for developing a flavorful crust.

3. Place the seasoned pork loin in a roasting pan. Roast in the preheated oven until a meat thermometer inserted into the thickest part of the roast registers 170°F (77°C). This should take approximately 2 hours, but always rely on the thermometer for accuracy.

4. While the pork loin is roasting, prepare the onion stuffing. In a medium frying pan, melt the butter over medium heat.

5. Add the chopped onions to the melted butter. Cook for about 10 minutes, stirring occasionally, until the onions are softened and translucent. Don’t rush this step; allowing the onions to slowly caramelize will enhance their natural sweetness.

6. Stir in the flour and cook for 1 minute, stirring constantly, to create a roux. This will help thicken the stuffing.

7. Gradually add the chicken base, ground nutmeg, lemon juice, and 1 cup of water to the onion mixture. Stir well to combine and dissolve the chicken base.

8. Continue cooking, stirring frequently, until the mixture thickens and becomes creamy. This should take about 5-7 minutes. The consistency should be thick enough to hold its shape but still easily spreadable.

9. Once the pork loin reaches 170°F (77°C), remove it from the oven. Increase the oven temperature to 350°F (175°C).

10. Using a sharp knife, make slices almost completely through the pork loin, leaving the bottom intact. Aim for slices about 3/4 inch thick, but feel free to adjust the thickness to your preference for serving sizes.

11. Stuff the spaces between the slices with the prepared onion filling. Spread any extra filling over the top of the roast.

12. Return the stuffed pork loin to the oven and bake for another 30 minutes, or until the top is nicely browned and the filling is heated through.

13. Remove the roast from the roasting pan and place it on a cutting board. Cover loosely with foil to keep it warm while you prepare the gravy.

14. To make the gravy, pour off any excess fat from the roasting pan, leaving the flavorful pan drippings.

15. Place the roasting pan on a burner over low heat. Stir in 1 cup of water to deglaze the pan, scraping up any browned bits from the bottom.

16. In a small bowl, combine the cornstarch and 1 tablespoon of water to create a slurry. Pour the cornstarch slurry into the pan drippings, stirring constantly.

17. Continue stirring until the gravy thickens to your desired consistency. You may need to adjust the heat or add more water to achieve the perfect thickness.

18. Remove the gravy from the heat. Slice the pork loin and serve immediately with the creamy onion stuffing and pan-dripping gravy.

Expert Tips & Tricks

• For an even more intense onion flavor, consider caramelizing the onions for a longer period, about 20-30 minutes, over low heat. Stir frequently to prevent burning.
• If you prefer a smoother gravy, strain it through a fine-mesh sieve after thickening.
• To ensure the pork remains juicy, let it rest for at least 10-15 minutes before slicing. This allows the juices to redistribute throughout the meat.
• For a make-ahead option, you can prepare the onion stuffing a day in advance and store it in the refrigerator. Bring it to room temperature before stuffing the pork.
• If the stuffing starts to brown too quickly in the oven, tent the roast loosely with foil.

Serving & Storage Suggestions

Serve the roast pork hot, sliced, with a generous spoonful of onion stuffing and a drizzle of pan-dripping gravy. This dish pairs wonderfully with roasted vegetables such as potatoes, carrots, or Brussels sprouts. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. The gravy can also be stored separately and reheated on the stovetop. Freezing is not recommended due to the texture of the onion stuffing.

Variations & Substitutions

• Add a splash of dry sherry or white wine to the onion stuffing for extra depth of flavor.
• If you don’t have chicken base, you can substitute it with chicken broth or stock.
• For a richer gravy, add a tablespoon of heavy cream or sour cream at the end of cooking.

FAQs (Frequently Asked Questions)

Q: Can I use a different cut of pork for this recipe?
A: While pork loin is ideal due to its lean texture and ability to slice easily, you could also use a pork shoulder or butt roast. However, these cuts require longer cooking times and will result in a different texture.

Q: Can I prepare the entire roast ahead of time and reheat it?
A: It’s best to prepare the stuffing ahead of time and stuff the roast just before baking. Reheating a fully cooked roast can dry it out.

Q: What if my onion stuffing is too dry?
A: Add a little more water or chicken broth to the stuffing until it reaches your desired consistency.

Q: How can I prevent the pork from drying out during roasting?
A: Make sure not to overcook the pork. Use a meat thermometer and remove it from the oven when it reaches 170°F (77°C). Letting it rest before slicing also helps retain moisture.

Q: Can I add other vegetables to the onion stuffing?
A: Yes, feel free to add other vegetables such as diced celery, carrots, or mushrooms to the onion stuffing for added flavor and texture.
