What matters
Choose caps similar in width to rolls so burgers are easy to hold.
Air fryer portobello halloumi burgers with lettuce and yogurt sauce. Start mushrooms first, then add grilling cheese and briefly toast the rolls.
Why this recipe works
Two filled wheat rolls as a meal. Large mushroom caps are cooked as vegetables, not used raw. If avoiding animal rennet, choose halloumi accordingly.
Recipe
Air fryer portobello halloumi burgers with lettuce and yogurt sauce. Start mushrooms first, then add grilling cheese and briefly toast the rolls.
Trim stems of two mushrooms flush and wipe caps dry. Cut halloumi into broad slices about 1 cm thick. Dry lettuce and slice tomato. Mix yogurt and mustard and refrigerate.
If required by the manufacturer, preheat for 3 minutes at 180 °C. Coat mushrooms with oil and pepper, gills up in a shallow dish. Precook about 6 minutes at 180 °C. Carefully drain released hot mushroom juices. Use a heatproof dish suitable for the appliance, leaving space around it for airflow. Do not preheat with loose paper.
Place halloumi on caps and cook about another 8 minutes at 180 °C. Mushrooms must be tender and cheese hot. Remove, split rolls and warm about 2 minutes at 160 °C.
Fill rolls with sauce, lettuce, tomato and mushroom-cheese filling. Do not pour leftover mushroom juice into bread. Serve without extra salt; halloumi is already salty.
