Ingredients
- 2 lbs beef tenderloin or sirloin
- 4 cups baby potatoes, quartered
- 2 tbsp olive oil
- 1 tsp dried thyme
- 1 tsp garlic powder
- 1 tsp salt
- 1/2 tsp black pepper
- 1 lemon, sliced (optional for garnish)
Instructions
- 1
Preheat your air fryer to 400°F. Getting the right temperature is crucial for that crispy goodness.
- 2
Toss baby potatoes in olive oil, thyme, garlic powder, salt, and pepper. Spread them evenly on a lined baking tray and cook for about 20 minutes at 375°F, shaking halfway through to ensure even cooking.
- 3
While the potatoes are roasting, season both sides of your beef with salt and black pepper.
- 4
Once the potatoes have been in for about 10 minutes, add the seasoned beef to the air fryer. Cook on each side for approximately 6-8 minutes (depending on desired doneness).
- 5
Let the meat rest for a few minutes before slicing. This helps lock in all that juicy goodness.
- 6
Serve hot with potatoes and a slice of lemon on top if you like an extra zing.

Alternatives & Substitutions
No air fryer? You can still achieve similar results by roasting the beef and potatoes in your oven at 375°F for about 20-25 minutes. Just make sure not to overcrowd your baking tray!
Want more veggie options? Feel free to toss some carrots or green beans into the air fryer alongside the potatoes. It’s all about balance, right?
Not a fan of beef? Chicken thighs work just as well here and can be even juicier if you’re careful not to overcook them.
FAQ (Frequently Asked Questions)
Can I use different cuts of meat? Absolutely! While tenderloin or sirloin are great options, feel free to experiment with other cuts like ribeye or flank steak. Just adjust the cooking time as needed based on thickness and desired doneness.
Do potatoes need to be peeled? Nope! Peeling is optional. Quarter them and give them a good rinse for an extra crispy skin.
What if I want it spicier? Add some red pepper flakes or cayenne powder to the seasoning mix for those who like a little heat.
How long can leftovers last? Leftovers are best eaten within 2-3 days. Store in an airtight container in the fridge and reheat in the microwave or air fryer to maintain crispiness.
Will this work with frozen potatoes? Thaw them first, pat dry thoroughly, and proceed as usual. Frozen may take slightly longer but should still come out crispy!
