Easy Step-by-Step Process for Air Fryer Pork Tenderloin With Creamy Roasted Garlic Sauce
Follow these steps to create a mouthwatering meal that's both quick and easy!
Steps for the Air Fryer Pork Tenderloin
Step 1: Pork Tenderloin Preparation

Begin by taking the pork tenderloin out of the fridge 30 minutes before you plan to cook. Trim away any excess fat and peel off the silver skin.
Let it rest at room temperature.
Step 2: Air Fryer Preheating

Turn on the air fryer, select "Air Crisp," and set it to 375°F for 25 minutes. Hit "Start" to preheat the air fryer.
Step 3: Seasoning the Pork

Mix together half the olive oil with dried rosemary, garlic powder, onion powder, salt, and black pepper in a bowl. Brush the tenderloin with the herbed oil mixture thoroughly.
Step 4: Preparing the Potatoes

Toss the diced potatoes into a bowl and add the remaining olive oil and the same herbs and spices until they're well coated.
Step 5: Cooking the Tenderloin and Potatoes

Once the air fryer indicates it's time to add food, carefully (it will be very hot) arrange the tenderloin in the air fryer, and nestle the seasoned potatoes around it. Close the air fryer to start cooking.
While this is cooking, prepare the roasted garlic cream sauce. Jump to the next section for the steps.
Step 6: Mid-Cooking Adjustments

After 10 minutes of cooking, open the air fryer to flip the tenderloin and shuffle the potatoes for an even roast.
Step 7: Checking Doneness

Check the pork's internal temperature after another 10 minutes. Aim for a reading slightly above 140°F, keeping in mind it will rise after resting.
Step 8: Finalizing the Potatoes

Once the pork is done, let it rest while you give the potatoes a final 5-minute crisp.
Step 9: Serving

Slice the rested tenderloin, plate with the potatoes, and drizzle generously with the roasted garlic cream sauce. Garnish with fresh herbs if you like, and serve hot.
Steps for the Roasted Garlic Cream Sauce
Step 1: Garlic and Milk Mixture

Mash roasted garlic with a fork in a bowl with whole milk, or blend for a smoother texture.
Step 2: Making the Roux

Melt butter in a pan over medium-low heat, then whisk in flour until smooth.
Step 3: Adding Cheeses and Final Touches

Stir in cream cheese and the garlic-milk mixture until the cheese melts.
Blend in grated Parmesan and salt, then gradually add milk until you've reached the perfect sauce consistency.
Step 4: Finalizing the Sauce

Remove from heat, and it's ready to enhance your dish!
Expert Tips for Making Air Fryer Pork Tenderloin
- Always preheat the air fryer.
Preheating your air fryer ensures that the pork and potatoes start cooking immediately at the right temperature, essential for that crispy finish.
- Don't overcrowd the meat in the air fryer.
Spacing out the food allows hot air to circulate freely, achieving an even cook and the perfect crust on your tenderloin and potatoes.
- Shake or turn the food halfway.
Shaking or turning the food halfway ensures all sides get direct heat, creating a uniformly cooked meal with a desirable golden exterior.
- Save your remaining garlic sauce.
If you have any roasted garlic cream sauce remaining, store it in an airtight container, and keep it in the fridge. You can use it later with rotisserie chicken breast, pasta, and roasted vegetables.

Frequently Asked Questions
Can I Use Other Types of Potatoes?
Absolutely, starchy varieties like russets or all-purpose potatoes like Yukon Golds are excellent for roasting and will work well with this recipe.
What if I Don't Have an Air Fryer?
You can still enjoy this meal by roasting the tenderloin in a conventional oven. Try baking at 400°F for about 25 to 30 minutes or until the desired doneness is reached.
How Do I Store Leftovers?
Place leftovers in a sealed container and refrigerate. For a just-cooked taste, reheat in the air fryer at 350°F for a few minutes or until heated through.
Can I Make the Sauce Ahead of Time?
Yes, prepare the sauce whenever convenient, store it in the fridge, and gently warm it on the stove or in the microwave when ready to serve.
How Do I Know When the Pork Is Done?
Use an instant read thermometer and look for a reading of 145°F in the thickest part of the tenderloin.
For example, if you remove the pork at 140°F, the residual heat will continue to cook the meat to the perfect temperature as it rests.
