Tips for Oven-Baked Perfection

• Pat the pork very dry before searing. Moisture on the surface will cause splattering and boil-over when searing.

• Don’t crowd the pork in the skillet when searing. Cook just a few pieces at a time for the best browning.

• Use a meat thermometer to ensure the pork reaches 145°F internally. This results in a safe, juicy interior.

• Let the baked pork rest before slicing. This allows the juices to reabsorb for moist, tender meat.

• Add any extra desired seasonings after cooking. The high oven heat intensifies flavors.

Cooking Times for Different Thicknesses

The thickness of your pork medallions will impact the baking time. Follow these guidelines:

• 1/2 inch thick: Bake for 15 minutes
• 3/4 inch thick: Bake for 17 minutes
• 1 inch thick: Bake for 20 minutes

Use an instant-read thermometer to confirm the pork has reached 145°F. If reheating leftovers, just warm to 145°F.

Oven Temperature Variations

While 400°F is ideal, you can bake the pork at a range of oven temps:

• 350°F: Will take slightly longer, around 17-22 minutes. Better if your medallions are on the thicker side.

• 375°F: The happy medium temperature, will take 15-20 minutes.

• 400°F: Best for thin, 1/2 inch thick medallions. Cooks in 15-17 minutes.

• 425°F: Can work if your oven runs hot. Check often to avoid overcooking.

No matter what temperature you use, always rely on an instant-read thermometer for perfectly cooked pork.

Juicy Pork Medallions Without the Oven

• Cook pork for 4-5 minutes per side until browned.

• Reduce heat to medium-low, cover and cook 5-7 more minutes, until 145°F internally.

The meat won’t have quite the same oven-roasted flavor, but will still be juicy and delicious.

The oven isn’t your only option—you can also toss the pork on the grill for delicious results:

• Preheat grill to medium-high heat.

• Grill medallions 4-5 minutes per side with the lid closed.
