Ingredients You’ll Need

• Frozen pork tenderloin — cooked straight from the freezer, no thawing required. A 2-pound tenderloin serves about six.
• Olive oil — helps the seasoning stick to the frozen surface and promotes even browning.
• Garlic powder — bold, savory backbone flavor.
• Onion powder — rounds out the seasoning with a mild sweetness.
• Paprika — adds subtle smokiness and a rich, appetizing color.
• Salt — draws out and boosts the pork’s natural flavor.
• Black pepper — gentle heat and balance.

How to Cook a Frozen Pork Tenderloin in the Air Fryer

Step 1 — Preheat. Preheat your air fryer to 400°F (200°C) for 3–5 minutes. Starting hot helps the outside brown while the inside catches up.

Step 2 — Season. Lightly brush the frozen pork tenderloin with olive oil, then sprinkle garlic powder, onion powder, paprika, salt, and black pepper over all sides. Press the seasoning in firmly so it sticks to the frozen surface.

Step 3 — Cook. Place the tenderloin in the air fryer basket and cook at 400°F (200°C) for 25 minutes.

Step 4 — Flip and finish. Turn the pork over and cook for another 15–25 minutes, depending on thickness, until the internal temperature reaches 145°F (63°C) on an instant-read thermometer. A standard 2-pound tenderloin usually lands around 40–45 minutes of total cook time; thicker cuts can take up to 50.

Step 5 — Rest and slice. Remove the pork and let it rest for 5–10 minutes so the juices redistribute. Slice into medallions and serve.

Recipe Variations

• Sweet and smoky: Add brown sugar and smoked paprika for a BBQ-style crust.
• Garlic herb: Mix dried rosemary, thyme, and parsley into the rub.
• Spicy kick: Add cayenne or chili powder for heat.
• Honey mustard glaze: Brush with honey and Dijon during the last 5 minutes of cooking.
• Teriyaki style: Swap the seasoning for a light teriyaki glaze and finish with sesame seeds.

Tips for the Juiciest Air Fryer Frozen Pork Tenderloin

• Always use a meat thermometer. Pork is safe and juiciest at 145°F (63°C). Cooking from frozen makes timing unpredictable, so temperature is the only reliable doneness check.
• Don’t overcrowd the basket. Cook one tenderloin at a time, or leave space between pieces so hot air can circulate.
• Adjust for size. Thicker tenderloins may need an extra 10–15 minutes; thinner ones finish faster.
• Add glaze at the end. Brush on BBQ sauce or honey mustard in the last 5 minutes so the sugars don’t burn.
• Let it rest. Five to ten minutes of resting locks in the juices before you slice.

Storing and Reheating

• Refrigerator: Store cooked pork in an airtight container for up to 4 days.
• Freezer: Slice and freeze in airtight containers or freezer bags for up to 3 months.
• Reheating: Warm in the air fryer at 350°F (175°C) for 5–8 minutes, until heated through. Skip the microwave when you can — it dries the meat out.

What to Serve With It

These medallions are endlessly flexible. Round out the plate with a cozy main-and-sides spread like my air fryer shepherd’s pie, or keep it casual alongside air fryer BBQ meatballs and a copycat Maid-Rite for a crowd. Craving more pork?
