How To Cook Beef Tenderloin Medallions In Air Fryer [FULL GUIDE]

Recommended Equipments:

Beef tenderloin medallions are the epitome of indulgent, melt-in-your-mouth meat. Known for their tenderness, delicate flavor, and quick-cooking nature, these cuts are perfect for a gourmet dinner without the prolonged preparation of a full roast. Traditionally seared in a pan or roasted in an oven, beef tenderloin medallions have now found a modern culinary ally: the air fryer.

Air fryers use rapid hot air circulation to cook food quickly and evenly while producing a crisp, caramelized exterior without the need for excessive oil. This makes them ideal for tenderloin medallions, preserving the juiciness of the meat while achieving a perfectly browned crust. Understanding the nuances of temperature, timing, and technique is crucial to unlocking the full potential of these luxurious cuts in an air fryer.

Optimal Air Fryer Temperature To Cook Beef Tenderloin Medallions In Air Fryer

For beef tenderloin medallions, the optimal air fryer temperature generally ranges between 400°F to 425°F (204°C to 218°C). This high temperature promotes the Maillard reaction-the chemical reaction that browns the meat and intensifies flavor-without overcooking the delicate interior.

• Lower temperatures (around 375°F / 190°C) will gently cook the medallions but may produce less browning and a more uniform color throughout.
• Higher temperatures (up to 450°F / 232°C) accelerate crust formation but increase the risk of overcooking the center if not monitored closely.

Selecting the right temperature ensures a balance: a golden, flavorful exterior while maintaining a tender, juicy center.

How Long To Cook Beef Tenderloin Medallions In Air Fryer

Cooking time depends on the thickness of the medallions and the desired doneness:

• 1-inch Thick Medallions

  • Rare: 6-7 minutes
  • Medium-rare: 8-9 minutes
  • Medium: 10-11 minutes
  • Medium-well: 12-13 minutes

• 1.5-inch Thick Medallions

  • Rare: 9-10 minutes
  • Medium-rare: 11-12 minutes
  • Medium: 13-14 minutes

It is recommended to flip the medallions halfway through the cooking time for even browning and consistent doneness.

How To Tell If It Is Done

The most reliable way to check doneness is with a meat thermometer:

• Rare: 120-125°F (49-52°C)
• Medium-rare: 130-135°F (54-57°C)
• Medium: 140-145°F (60-63°C)
• Medium-well: 150-155°F (65-68°C)

Visual cues can also help: the exterior should be golden brown with clear grill marks, and the juices should run lightly pink for medium-rare. Overcooked tenderloin tends to lose its vibrant color and becomes noticeably firmer to the touch.

Ingredients Needed

• 1-1.5 lb beef tenderloin, cut into 1-1.5 inch medallions
• 1-2 tbsp olive oil or melted butter
• Salt (preferably kosher or sea salt)
• Freshly ground black pepper
• Optional: garlic powder, smoked paprika, rosemary, or thyme for extra flavor

Additional optional finishing touches: a pat of herb butter, balsamic glaze, or a light drizzle of truffle oil to enhance the richness of the medallions.

How To Cook Beef Tenderloin Medallions In Air Fryer

1. Preheat the air fryer: Set to 400-425°F (204-218°C) for about 3-5 minutes. Preheating ensures even cooking and immediate browning.
2. Prepare the medallions: Pat the beef dry with paper towels. Rub each medallion lightly with olive oil or butter, then season generously with salt, pepper, and any optional spices.
3. Arrange in the air fryer basket: Place medallions in a single layer without overcrowding to allow proper air circulation.
4. Cook: Air fry according to the timing guide above, flipping halfway through.
5. Rest: Remove medallions and allow them to rest for 5 minutes. Resting redistributes juices and ensures maximum tenderness.
6. Serve: Optionally, top with herb butter or a sauce of choice and enjoy immediately.

What If I Use A Different Air Fryer Temperature?

• Lower temperature: Extends cooking time and reduces browning, which may yield medallions that are less caramelized but more evenly cooked inside.
• Higher temperature: Accelerates browning, potentially producing a crispy exterior but increasing the risk of an overcooked center. Always monitor closely if exceeding 425°F.

What If I Use A Different Air Fryer Cooking Time?

• Shorter cooking time: Will result in rarer medallions; if undercooked, allow them to rest or briefly return to the air fryer.
• Longer cooking time: Moves the medallions toward medium-well or well-done. Excessive time risks drying out the meat. Timing adjustments should always be paired with temperature considerations.

When Things Go Wrong

Common issues include:

• Overcooked medallions: Usually due to high temperature or extended cooking time. Solution: slice thinly and serve with a sauce to add moisture.
• Undercooked medallions: Return to the air fryer for 1-2 minute increments, checking temperature frequently.
• Uneven browning: Likely due to overcrowding. Always ensure air circulation by cooking in a single layer.
• Dry texture: Can result from skipping the resting period; resting is critical to retain juices.

Expert Tips

1. Use a digital meat thermometer for perfect doneness every time.
2. Don’t skip preheating-it guarantees immediate sear and Maillard browning.
3. Pat meat dry before seasoning to achieve a crusty exterior.
4. Flip halfway for uniform color and texture.
5. Experiment with finishing touches like compound butter, garlic, or fresh herbs to elevate flavor.
6. Let medallions rest for at least 5 minutes to allow juices to redistribute.

FAQs

What Is The Ideal Temperature To Cook Beef Tenderloin Medallions In An Air Fryer?

The ideal temperature to cook beef tenderloin medallions in an air fryer is around 400°F (200°C). This high heat helps achieve a nice sear on the outside while keeping the inside tender and juicy.

How Long Should I Cook Beef Tenderloin Medallions In An Air Fryer?

Cooking time for beef tenderloin medallions in an air fryer typically ranges from 8 to 12 minutes, depending on the thickness of the medallions and your preferred level of doneness. For medium-rare, aim for about 8-9 minutes, and for well-done, around 12 minutes.

Should I Marinate The Beef Tenderloin Medallions Before Air Frying?

While marinating is optional, marinating the beef tenderloin medallions for at least 30 minutes to 1 hour can enhance the flavor and tenderness. You can use a simple marinade with olive oil, garlic, herbs, and seasonings, or a store-bought marinade of your choice.

How Can I Ensure The Beef Tenderloin Medallions Are Cooked Evenly In An Air Fryer?

To ensure even cooking, make sure the beef tenderloin medallions are not overcrowded in the air fryer basket. Arrange them in a single layer, leaving space between each piece for proper air circulation. If necessary, cook them in batches.

Do I Need To Flip The Beef Tenderloin Medallions During Cooking In The Air Fryer?

Yes, flipping the beef tenderloin medallions halfway through the cooking process ensures they cook evenly on both sides and helps develop a uniform crust. Use tongs to flip them carefully without disturbing their shape.

What Are The Best Seasonings For Beef Tenderloin Medallions In An Air Fryer?

A simple seasoning of salt, pepper, and garlic powder works wonderfully. You can also add fresh or dried herbs like rosemary or thyme, or use a steak seasoning blend for added flavor. For a more intense flavor, consider marinating the beef with balsamic vinegar or soy sauce.

How Do I Check The Doneness Of Beef Tenderloin Medallions In The Air Fryer?

The best way to check doneness is to use a meat thermometer. For medium-rare, the internal temperature should be about 130°F (54°C); for medium, around 140°F (60°C); and for well-done, 160°F (71°C). Insert the thermometer into the center of the thickest part of the medallion.
