Air Fryer Rosemary Olive Savory Muffins

These savory muffins combine the aromatic depth of fresh rosemary with the briny richness of Kalamata olives, baked to a tender finish in an air fryer. The technique relies on using olive oil as the primary fat source and baking at a slightly lower temperature than traditional recipes to ensure the center remains moist while the exterior achieves a pleasant crispness without burning.

Recipe Overview

Servings: 12 muffins
Preparation time: 15 minutes (includes mixing and cooling)
Air frying time per batch: 12–14 minutes at 340°F (170°C)
Total elapsed time: Approximately 28 minutes

Equipment Requirements

This recipe requires a standard air fryer basket or oven tray. For best results, use 6 individual muffin cups or ramekins that fit within the appliance without blocking airflow. Do not overfill; fill each container to no more than three-quarters full to allow for even rising and steam escape.

Ingredients

All-purpose flour: 180g, sifted
Baking powder: 12g
Sugar: 30g (white or caster sugar)
Unsalted butter: 60g, softened to room temperature
Egg large: 1 unit, at room temperature
Whole milk: 45ml
Fresh rosemary leaves: 5g, finely chopped
Kalamata olives: 30g, pitted and roughly halved
Olive oil extra virgin: 20ml, measured clean before contact with raw batter
Salt fine sea: 3g

Instructions

Prepare the rosemary mixture: In a small bowl, combine the chopped rosemary leaves with the olive oil. Let this sit for 5 minutes to allow the oil to infuse with the herb flavor.

Mix dry ingredients: In a large mixing bowl, sift together the all-purpose flour, baking powder, and fine sea salt. Whisk briefly to ensure even distribution of the leavening agent.

Combine wet ingredients: Add the softened butter, room temperature egg, and whole milk to a separate smaller bowl. Beat with a fork or whisk until the mixture is smooth and slightly pale in color.

Combine mixtures: Pour the butter-egg mixture into the flour mixture. Gently fold using a spatula until just combined. Do not overmix, as this develops gluten and can lead to a tough texture.

Incorporate olives and oil: Fold in the pitted Kalamata olives and the infused rosemary-oil mixture. Ensure the oil is distributed evenly throughout the batter but not separated into pools.

Preheat the air fryer: Set your air fryer to 340°F (170°C) and let it run for 3 minutes with the basket empty. This ensures consistent heat distribution before baking.

Bake the muffins: Spoon the batter into the prepared muffin cups or ramekins, filling them about two-thirds full. Place the tray in the center of the air fryer basket. Cook for 12 minutes. At the 10-minute mark, open the appliance and gently shake the tray to ensure even browning.

Check doneness: Insert a wooden skewer into the center of one muffin. It should come out clean or with only a few moist crumbs attached. If it comes out wet, return to the air fryer for 1–2 minutes at the same temperature.

Cool and serve: Remove the tray from the air fryer immediately after cooking. Allow the muffins to cool in the basket for 5 minutes before transferring them to a wire rack. They will firm up as they cool.

Troubleshooting Tips

Muffins are dry: This usually indicates overmixing or undercooking. Ensure you stop mixing as soon as the flour disappears. If they are still wet in the center after 14 minutes, they likely need a minute more time.

Batter is too thick: If the batter feels stiff, add an additional teaspoon of milk to reach a pourable consistency similar to thick pancake batter.

Olive flavor is muted: Ensure you are using high-quality Kalamata olives and that the rosemary has been steeped in the oil for at least 5 minutes before adding.

Serving and Storage

Serve warm with a dollop of sour cream or Greek yogurt, or alongside a simple green salad. These muffins are best eaten within 24 hours for optimal texture.

For storage, place cooled muffins in an airtight container at room temperature for up to 2 days. To refrigerate longer term, store in the fridge for up to 5 days; reheat in the air fryer at 300°F (150°C) for 3–4 minutes or microwave briefly.

Frequently Asked Questions

Can I bake these in a conventional oven?

You can, but you must adjust the time and temperature. Preheat your oven to 375°F (190°C) and bake for approximately 20–25 minutes, checking doneness with a skewer.

Is this recipe gluten-free?

No, it contains all-purpose flour which includes wheat. To make these gluten-free, you would need to substitute the flour with a certified gluten-free blend and adjust liquid quantities slightly due to different absorption rates.

How do I know if they are fully cooked?

Rely on the internal temperature of the muffin center rather than just time. Insert a food thermometer into the center; it should read at least 190°F (88°C) for a fully baked, tender crumb.
