If you want a fast, easy, and less messy way to prepare a fantastic steak dinner, learning how to cook beef medallions in air fryer is a game-changer. This method delivers a beautifully seared exterior and a tender, juicy interior with minimal effort and cleanup, making it perfect for weeknights or special occasions.
Beef medallions are simply small, round steaks cut from the tenderloin. They are naturally lean and tender, which makes them ideal for quick cooking. Using an air fryer concentrates the heat around the meat, creating a wonderful crust while keeping the inside perfectly cooked to your liking. Let’s get started on making your best air-fried steak yet.
How to Cook Beef Medallions in Air Fryer
This is your core, step-by-step guide. Follow these instructions for consistently excellent results.
What You’ll Need
- Beef tenderloin medallions, 1 to 1.5 inches thick (about 6-8 oz each)
- High-heat cooking oil (avocado, grapeseed, or canola oil work well)
- Kosher salt and freshly ground black pepper
- Optional seasonings: garlic powder, onion powder, smoked paprika, rosemary, or thyme
- An air fryer
- Tongs
- Instant-read meat thermometer (highly recommended)
Step-by-Step Cooking Instructions
1. Preparing the Beef Medallions
First, take the medallions out of the refrigerator about 20-30 minutes before cooking. Letting them come closer to room temperature helps them cook more evenly. Pat them completely dry with paper towels. This is crucial—moisture on the surface will steam the meat instead of allowing it to sear.
Next, drizzle a light coat of oil onto both sides of each medallion. Then, generously season all over with salt, pepper, and any other dry seasonings you prefer. Don’t be shy with the salt; it brings out the natural flavor of the beef.
2. Preheating the Air Fryer
Preheat your air fryer to 400°F (200°C) for about 3-5 minutes. Preheating ensures the cooking environment is hot immediately, which is key for getting that nice sear. If your model doesn’t have a preheat function, just run it empty at the cooking temperature for a few minutes.
3. Cooking Time and Temperature
Place the seasoned medallions in the air fryer basket in a single layer. Make sure they are not touching or overlapping so air can circulate properly. Cook at 400°F (200°C). The exact time will depend on your desired doneness and the thickness of your steaks.
Here is a reliable guide for 1-inch thick medallions:
- Rare: 6-8 minutes (120-125°F internal temp)
- Medium Rare: 8-10 minutes (130-135°F internal temp)
- Medium: 10-12 minutes (140-145°F internal temp)
- Medium Well: 12-14 minutes (150-155°F internal temp)
Important: Flip the medallions halfway through the cooking time using tongs. This ensures even browning on both sides. The best way to know for sure is to use a meat thermometer. Check the temperature in the thickest part of the steak towards the end of the estimated cook time.
4. Resting is Non-Negotiable
Once cooked, transfer the beef medallions to a clean plate or cutting board. Tent them loosely with foil and let them rest for 5-10 minutes. This allows the juices, which have been driven to the center by the heat, to redistribute throughout the meat. If you cut into them immediately, those precious juices will end up on your plate instead of in your steak.
Pro Tips for the Best Results
- Thickness Matters: Try to get medallions of even thickness. If one is much thicker, you can gently press it with the palm of your hand to even it out a bit.
- Avoid Overcrowding: Cook in batches if necessary. Overcrowding leads to steaming and uneven cooking.
- Butter Baste (Optional Finish): For extra richness, after flipping the steak, you can place a small pat of butter and a sprig of thyme or rosemary on top of each medallion for the last few minutes of cooking.
- Deglaze the Basket: After removing the steaks, you can add a splash of broth or red wine to the hot air fryer basket (be careful of steam) to loosen the browned bits. Pour this over your rested steaks for a simple, flavorful sauce.
Choosing the Right Beef Medallions
Not all beef medallions are created equal. Starting with good quality meat makes a huge difference in the final outcome.
Cut and Grade
Authentic beef medallions come from the tenderloin, which is the most tender cut on the cow. You might also see “filet mignon” used interchangeably, though filet mignon is typically the very center cut. Look for medallions with a bright red color and some marbling (thin white streaks of fat within the muscle). This intramuscular fat melts during cooking, adding flavor and juiciness. USDA Choice or Prime grades will have better marbling than Select.
Thickness Guide
For air frying, a thickness of 1 to 1.5 inches is ideal. Thinner cuts will cook too quickly and are easy to overcook. Thicker cuts may require a slightly lower temperature or longer time to cook through without burning the outside. If you can, ask your butcher to cut them to your preferred thickness.
Seasoning and Marinade Ideas
While simple salt and pepper is classic, you can easily customize the flavor profile of your air fryer beef medallions.
Simple Dry Rubs
- Classic Steakhouse: Salt, black pepper, garlic powder, and a touch of onion powder.
- Smoky & Spicy: Salt, smoked paprika, chili powder, and a pinch of cumin.
- Herb Crusted: Salt, pepper, and a mix of dried rosemary, thyme, and oregano.
Quick Marinades
Marinating can add another layer of flavor, especially since tenderloin is lean. Marinate for at least 30 minutes, or up to 4 hours in the refrigerator.
- Garlic & Herb: Olive oil, minced garlic, fresh chopped rosemary, thyme, salt, and pepper.
- Balsamic: Balsamic vinegar, olive oil, Dijon mustard, and a little honey.
- Asian-Inspired: Soy sauce, sesame oil, grated ginger, and a minced garlic clove.
Remember to pat the medallions dry again after marinating before applying a little oil and cooking.
Air Fryer Settings and Adjustments
Understanding your appliance will help you avoid common pitfalls.
Basket vs. Oven-Style Air Fryers
Both types work well. Basket-style models (like Philips or Ninja) often have a drawer that shakes or requires manual flipping. Oven-style models (like Cuisinart or Breville) with racks may cook even more evenly because you can space them out. The key is to know your model’s hot spots and adjust placement if needed.
Temperature Accuracy
Air fryer temperatures can sometimes run a bit hot or cool. An inexpensive oven thermometer can help you verify the actual temperature inside your appliance. If you find your food is often cooking faster than recipes state, try reducing the temperature by 25°F on your next attempt.
Serving Suggestions
Your perfectly cooked beef medallions deserve great sides. Here are some ideas that pair wonderfully and are also easy to prepare.
- Classic Sides: Creamy mashed potatoes, roasted asparagus, garlic sautéed mushrooms, or a simple green salad with a tangy vinaigrette.
- For a Lighter Meal: Serve over a bed of arugula with shaved Parmesan and a lemon wedge, or alongside roasted cherry tomatoes and zucchini.
- Sauces: A pat of compound butter (like blue cheese or herb butter) melting on top is effortless and delicious. A quick pan sauce made on the stovetop with the drippings from the air fryer basket (see Pro Tips) also works great.
Storing and Reheating Leftovers
Leftover cooked beef medallions are a treat. Store them in an airtight container in the refrigerator for up to 3-4 days.
To reheat, the air fryer is your best friend again. Reheat at 350°F for 3-4 minutes, just until warmed through. This helps preserve the texture better than a microwave, which can make the steak tough and rubbery. You can also slice them cold and add to salads or sandwiches.
Common Mistakes to Avoid
- Not Drying the Steak: This is the number one reason for a lack of sear.
- Skipping the Preheat: Putting cold meat into a cold air fryer starts the cooking process too slowly.
- Overcrowding the Basket: This is the main cause of uneven, steamed results.
- Skipping the Rest: You’ll lose a lot of moisture and end up with a drier steak.
- Relying Solely on Time: Always use a meat thermometer for accuracy. Cooking times are estimates and vary between appliances.
Frequently Asked Questions (FAQ)
Can I cook frozen beef medallions in the air fryer?
Yes, you can, but the results won’t be as good as with thawed meat. You’ll need to add 5-8 minutes to the cooking time. The exterior may not sear as effectively because moisture from the frozen steak will release during cooking. Thawing in the refrigerator first is always recommended for the best quality.
Do I need to add oil to the air fryer basket?
No, you should not pour oil into the bottom of the basket. The medallions themselves should be lightly coated in oil. This ensures they brown properly without causing excessive smoke from oil dripping into the bottom of the appliance.
Why are my beef medallions tough?
Toughness usually means the steak is overcooked. Since tenderloin is very lean, it can become dry and chewy if cooked past medium. Using a meat thermometer to avoid overcooking is the best solution. Also, ensure you are slicing against the grain when you serve it.
Can I cook other cuts of steak this way?
Absolutely. The air fryer is great for many steaks like ribeye, strip, or sirloin. Adjust cooking times based on thickness and fat content. Fattier cuts like ribeye may produce more smoke, so keep an eye on them.
How do I prevent smoke from my air fryer when cooking steak?
Smoke usually comes from fat or oil dripping onto the hot heating element. Trimming excess fat, using a light hand with oil, and ensuring the air fryer is clean (especially the bottom drawer) can help. Placing a slice of bread or a little water in the bottom drawer can also catch drips, but check your manufacturer’s instructions first.
What’s the difference between air frying and pan-searing?
Pan-searing gives a slightly better crust because of direct contact with a very hot metal surface. Air frying is more hands-off, creates less mess and splatter, and can yield excellent results with less oil. It’s a fantastic method for a quick, convenient, and still delicious steak.
Mastering how to cook beef medallions in air fryer opens up a world of simple, satisfying meals. With a few key steps—drying the meat, preheating, not overcrowding, using a thermometer, and resting—you’ll achieve a restaurant-quality result right at home. Experiment with your favorite seasonings and sides to make the meal your own. The air fryer’s convenience and consistent heat make it a reliable tool for preparing a tender, flavorful steak any night of the week.
