Air Fryer Mushrooms and Red Onions are soft, golden, and full of rich flavor, with a bit of sweetness from the onions and a deeper, earthy taste from the mushrooms.
Clean the mushrooms by wiping them with a damp cloth or paper towel to remove any dirt.
Slice the mushrooms and onions, making sure they are uniform slices for even cooking.
Place the olive oil, salt, pepper, paprika, and thyme in a large mixing bowl and then give it a whisk until all are combined.
Add the sliced mushrooms and onions, and then toss until everything is evenly coated.
Set your air fryer to 383°F (195°C) and then place the seasoned mushrooms and onions in the air fryer basket in a single layer. Avoid overcrowding to ensure they cook evenly.
Air fry for 10–12 minutes, shaking the basket halfway through to help even browning. The vegetables should be tender with slightly crispy edges.
Notes
Use a damp cloth or paper towel to wipe mushrooms clean. Avoid soaking them — they absorb water, which can lead to soggy texture.
Try to slice both the mushrooms and onions as evenly as possible. This helps them cook at the same rate.
Marinate the vegetables for 15-30 minutes before cooking for enhanced taste.
Don’t overcrowd the basket — mushrooms need space to brown.
