Prep the Oven & Pan

Preheat oven to 275°F (135°C).

Lightly oil a large baking dish or cast iron pan.

Season the Pork

Pat pork slices dry with paper towels.

Mix salt, pepper, garlic powder, onion powder, smoked paprika, and thyme/rosemary in a small bowl.

Rub seasoning mixture evenly onto all sides of each pork slice.

Assemble the Dish

Lay seasoned pork slices flat in a single layer in the dish.

Drizzle with olive oil.

Pour ½ cup broth into the bottom of the pan if using (adds moisture and prevents sticking).

Slow-Bake Covered

Cover tightly with foil or lid.

Bake in the center of the oven for 4.5 to 5.5 hours, depending on thickness.

The pork should be fork-tender but still hold its shape.

Uncover & Finish

Remove foil. Increase heat to 350°F (175°C).

Return pork to oven for 25–30 minutes to brown and slightly crisp the tops.

Optional: Broil briefly for a more roasted finish.

Rest & Serve

Let rest for 10 minutes, loosely covered with foil.

Serve with spooned pan juices and your favorite sides: mashed potatoes, roasted vegetables, cauliflower mash, or rice.
