Want potatoes that are crunchy on the outside, fluffy in the middle, and packed with garlic flavor? These Air Fryer Crispy Smash Potatoes with Garlic Aioli turn simple baby potatoes into a delicious side dish with a golden crust and tender center. A creamy garlic dipping sauce adds a rich, tangy finish that makes every bite even better.
The secret is to boil the potatoes until fork-tender, gently smash them, and air fry them with olive oil and seasonings. Smashing creates more surface area, which helps the edges turn crisp while the centers stay soft. You get the texture of roasted potatoes without needing to heat a full-size oven.
This recipe uses everyday ingredients and simple steps, making it a great choice for weeknight dinners, weekend cookouts, or game-day snack platters. Serve the potatoes alongside burgers, grilled chicken, steak, or roasted vegetables. You can also enjoy them as an appetizer with homemade garlic aioli for dipping.

Ingredients for Air Fryer Crispy Smash Potatoes with Garlic Aioli
Use small potatoes that cook evenly and hold their shape when smashed.
For the Smash Potatoes
- 1 1/2 pounds baby Yukon Gold or baby red potatoes
- 2 tablespoons olive oil
- 3 garlic cloves, minced
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon dried rosemary or Italian seasoning
- 1/2 teaspoon salt, or to taste
- 1/4 teaspoon black pepper
- 2 tablespoons grated Parmesan cheese, optional
- 1 tablespoon chopped fresh parsley, optional
For the Garlic Aioli
- 1/2 cup mayonnaise
- 1–2 garlic cloves, finely minced or grated
- 1 tablespoon fresh lemon juice
- 1 teaspoon Dijon mustard, optional
- 1 teaspoon olive oil
- A pinch of salt
- A pinch of black pepper
Ingredient tip: Yukon Gold potatoes have a naturally buttery texture, while baby red potatoes hold their shape well. Choose potatoes of similar size so they cook evenly. For the aioli, adjust the garlic and lemon juice to suit your taste.
How to Make Air Fryer Crispy Smash Potatoes with Garlic Aioli
Follow these steps for tender potatoes with golden, crunchy edges and a flavorful dipping sauce.
Step 1: Wash the Potatoes
Rinse the baby potatoes under cool running water and scrub away any dirt. Leave the skins on because they help the potatoes hold together during smashing and add texture after air frying.
Choose potatoes that are roughly the same size. If some are much larger than the others, cut them in half after cooking or allow extra boiling time.
Step 2: Boil Until Fork-Tender
Place the potatoes in a large saucepan and cover them with water. Add a small pinch of salt, then bring the water to a boil.
Reduce the heat and simmer for approximately 12–18 minutes, depending on potato size. The potatoes are ready when a fork slides into the center easily without causing them to fall apart.
Drain the potatoes thoroughly and let them sit for about 5 minutes. Removing excess moisture helps the edges crisp more effectively in the air fryer.
Step 3: Prepare the Garlic Aioli
While the potatoes cool, combine the mayonnaise, minced garlic, lemon juice, Dijon mustard, olive oil, salt, and black pepper in a small bowl.
Stir until smooth and creamy. Taste the sauce and add more lemon juice for brightness or a little extra garlic for a stronger flavor.
Cover and refrigerate the aioli while you prepare the potatoes. Chilling it briefly allows the garlic flavor to develop.
Food safety tip: This version uses mayonnaise as its base, making it quick to prepare without raw eggs. Keep the sauce refrigerated until serving.
Step 4: Smash the Potatoes
Place the drained potatoes on a clean cutting board or sturdy tray. Use the bottom of a drinking glass, a potato masher, or a flat spatula to press each potato gently.
Aim for a thickness of about 1/2 inch. Press firmly enough to flatten the potato and split the skin slightly, but not so hard that it breaks into many pieces.
The rough edges created during smashing become crisp during air frying. If a potato crumbles, gently press the pieces back together before seasoning.
Step 5: Mix the Seasoning
In a small bowl, combine the olive oil, minced garlic, paprika, garlic powder, rosemary or Italian seasoning, salt, and black pepper.
Brush or spoon the mixture over both sides of the smashed potatoes. Make sure the oil and seasonings reach the uneven edges, where most of the crunch develops.
If using fresh minced garlic, spread it evenly and avoid piling it onto the exposed edges because small garlic pieces can burn at high heat.
Step 6: Preheat the Air Fryer
Preheat the air fryer to 400°F for approximately 3 minutes, following your appliance’s instructions.
If your model does not require preheating, follow the manufacturer’s guidance. Lightly grease the basket with an air-fryer-safe oil if needed to prevent sticking.
Step 7: Arrange the Potatoes in a Single Layer
Place the seasoned potatoes in the basket with a little space between each piece. Avoid overlapping them because crowded potatoes trap moisture and brown less evenly.
Cook in batches if necessary. Keeping the potatoes in a single layer allows hot air to reach the rough edges and helps create a crisp surface.
Step 8: Air Fry Until Crispy
Air fry at 400°F for approximately 12–18 minutes, checking around the 10-minute mark. Carefully turn the potatoes halfway through cooking if needed.
The finished potatoes should have golden-brown edges and a crisp exterior. If they need more color, continue cooking for another 2–3 minutes while watching closely.
Cooking time varies with potato thickness and air fryer performance. If the garlic begins to darken too quickly, lower the temperature slightly and continue cooking until the potatoes reach your preferred texture.
Step 9: Add Parmesan and Fresh Herbs
If using Parmesan cheese, sprinkle it over the potatoes during the final 2–3 minutes of cooking. This allows the cheese to melt and lightly brown without becoming too dark.
Transfer the cooked potatoes to a serving plate and add chopped parsley. Taste one and adjust the seasoning with a little extra salt or black pepper if needed.
Step 10: Serve with Garlic Aioli
Place the warm potatoes on a platter with the chilled garlic aioli in a small dipping bowl. Serve immediately for the best contrast between the crispy exterior and creamy sauce.
For extra freshness, add a squeeze of lemon juice or a sprinkle of chopped chives. Keep the aioli separate until serving so the potato crust stays crisp.
Tips for Extra-Crispy Smash Potatoes
Use these simple techniques to improve browning and texture.
- Choose small potatoes: Baby potatoes are easier to boil, smash, and cook evenly.
- Dry them after boiling: Excess moisture can prevent a crisp crust from forming.
- Do not smash too thin: About 1/2 inch thick helps the potatoes stay together.
- Use enough oil: A thin, even coating encourages browning without making the potatoes greasy.
- Leave space in the basket: Air circulation is essential for crisp edges.
- Season both sides: This gives the potatoes flavor throughout.
- Add Parmesan near the end: Late seasoning helps prevent the cheese from burning.
- Check early: Air fryer temperatures vary, so monitor the potatoes during the final minutes.
Easy Variations to Try
Change the seasonings or dipping sauce to create a different flavor with the same basic method.
Parmesan Garlic Smash Potatoes
Add extra grated Parmesan and a little dried parsley during the final minutes of cooking. The cheese creates a savory coating that pairs well with the garlic aioli.
Spicy Smash Potatoes
Add 1/4 teaspoon of cayenne pepper or red pepper flakes to the seasoning mixture. Serve with the cool garlic dip to balance the heat.
Lemon Herb Smash Potatoes
Replace the paprika with lemon zest and add fresh thyme or rosemary. Finish with a small squeeze of lemon juice before serving.
Cajun Smash Potatoes
Use 1–2 teaspoons of Cajun seasoning instead of the paprika and dried herbs. Check the salt level first because many Cajun blends already contain salt.
Dairy-Free Smash Potatoes
The potatoes are naturally dairy-free when made without Parmesan. Use a dairy-free mayonnaise for the aioli and check the ingredient labels to ensure they suit your needs.
What to Serve with Crispy Smash Potatoes
These crunchy potatoes work well with many everyday meals.
- Grilled chicken: A simple protein that pairs well with garlic and herbs.
- Burgers: Serve the potatoes as a crispy alternative to traditional fries.
- Steak: The creamy aioli complements the savory flavor of grilled or pan-seared steak.
- Roasted vegetables: Pair with carrots, zucchini, or broccoli for a vegetable-focused meal.
- Grilled fish: Lemon and garlic flavors work well with salmon or white fish.
- Sandwiches and wraps: Add the potatoes as a crunchy side for lunch.
- Party platters: Serve with ranch, ketchup, or garlic aioli for dipping.
For a simple weeknight dinner, pair the potatoes with grilled chicken and a green salad. For a party, serve them in a large bowl with two or three dipping sauces.
Storage and Reheating Instructions
How to Store Leftover Smash Potatoes
Let the potatoes cool, then place them in an airtight container and refrigerate within 2 hours of cooking. Use refrigerated leftovers within 3–4 days.
Store the garlic aioli separately in a covered container in the refrigerator. Do not leave mayonnaise-based sauce at room temperature for extended periods.
How to Reheat Smash Potatoes in the Air Fryer
Preheat the air fryer to 375°F. Arrange the cold potatoes in a single layer and heat for approximately 3–6 minutes, checking until they are hot and crisp.
Add another minute if needed. Avoid reheating them with the aioli because the sauce is best served cold.
Can You Freeze Smash Potatoes?
Yes. Freeze the cooked and cooled potatoes in a single layer until firm, then transfer them to a freezer-safe container. For best quality, use within 2 months.
Reheat from frozen in the air fryer at 375°F, allowing extra time until the centers are hot and the edges are crisp. The texture may be slightly softer than freshly cooked potatoes.
Common Mistakes to Avoid
- Boiling the potatoes too long: Overcooked potatoes may fall apart when smashed.
- Skipping the drying step: Wet surfaces make crisping harder.
- Smashing too aggressively: Broken pieces may stick to the basket or burn.
- Using too little oil: The potatoes may turn dry instead of golden and crisp.
- Overcrowding the basket: Trapped moisture can soften the edges.
- Adding fresh garlic too early at high heat: Small garlic pieces may burn before the potatoes finish cooking.
- Using too much lemon juice in the aioli: Excess liquid can make the sauce thin.
- Serving the potatoes after they sit covered: Trapped steam softens the crust.
