How to Make Air Fryer Mushrooms and Onions
Quick Overview

The key to success lies in proper slicing and seasoning – thick enough pieces to maintain texture, but thin enough to cook evenly. The result is perfectly caramelized vegetables with crispy edges and tender centers.
Prep Time: 5 minutes Cook Time: 12-15 minutes Total Time: 20 minutes Servings: 4
Key Ingredients for Air Fryer Mushrooms and Onions
- 1 pound mixed mushrooms (button, cremini, or baby bella), sliced ¼-inch thick
- 2 large yellow onions, sliced into half-moons
- 3 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 2 tablespoons balsamic vinegar (optional)
- 2 tablespoons fresh parsley, chopped (for garnish)
Pro tip: Choose mushrooms that are firm and dry to the touch for the best results. Avoid pre-sliced mushrooms as they tend to release more moisture during cooking.
Step-by-Step Instructions
Step 1: Prepare the Vegetables Clean the mushrooms with a damp paper towel and slice them ¼-inch thick. Peel the onions and cut them into half-moon slices, keeping them roughly the same thickness as the mushrooms for even cooking.
Step 2: Season the Mixture In a large bowl, combine the sliced mushrooms and onions. Drizzle with olive oil and sprinkle with garlic powder, thyme, salt, and pepper. Toss everything together until the vegetables are evenly coated with oil and seasonings.
Step 3: Preheat the Air Fryer Preheat your air fryer to 380°F (193°C) for 3-5 minutes. This ensures even cooking from the moment you add the vegetables.
Step 4: Cook the First Round Place the seasoned mushrooms and onions in the air fryer basket in a single layer. Don’t overcrowd – cook in batches if necessary. Air fry for 8 minutes, then shake the basket or stir the vegetables.
Step 5: Finish Cooking Continue cooking for another 4-7 minutes, checking every 2 minutes and stirring as needed. The vegetables should be golden brown and tender when done.
Step 6: Final Touches Remove from air fryer and drizzle with balsamic vinegar if using. Garnish with fresh parsley and serve immediately while hot.
What to Serve Air Fryer Mushrooms and Onions With
These versatile vegetables pair beautifully with numerous main dishes. Serve them alongside grilled steak, roasted chicken, or pork chops for a complete meal. They also make an excellent topping for baked potatoes, pasta dishes, or grain bowls.
For a lighter option, try them over quinoa or rice with a sprinkle of cheese. They’re also fantastic as a pizza topping or stirred into scrambled eggs for a gourmet breakfast. The rich, savory flavor complements both hearty winter meals and fresh summer dishes.
Consider serving with crusty bread to soak up any delicious juices, or pair with a crisp white wine like Sauvignon Blanc or Pinot Grigio that won’t overpower the earthy flavors.
Top Tips for Perfecting Air Fryer Mushrooms and Onions
Don’t Overcrowd the Basket
The biggest mistake people make is cramming too many vegetables into the air fryer at once. This creates steam instead of the crispy texture you want. Cook in batches if necessary – it’s worth the extra few minutes for perfect results.
Pat Mushrooms Dry
Mushrooms naturally contain a lot of moisture. Pat them dry with paper towels before seasoning to prevent them from steaming in their own juices. This simple step makes a huge difference in achieving that coveted crispy texture.
Adjust Cooking Time for Different Mushroom Types
Delicate mushrooms like oyster or shiitake cook faster than dense button mushrooms. Start checking for doneness 2 minutes earlier if using more delicate varieties. Portobello mushrooms may need an extra 2-3 minutes.
Experiment with Seasonings
While the basic recipe is delicious, don’t be afraid to experiment. Try adding smoked paprika for a smoky flavor, red pepper flakes for heat, or fresh herbs like rosemary or sage for an aromatic twist.
Use the Right Oil
Olive oil works perfectly for most preparations, but avocado oil has a higher smoke point and neutral flavor if you prefer. Avoid butter as it can burn at high temperatures.
Storing and Reheating Tips
Refrigerator Storage: Store leftover air fryer mushrooms and onions in an airtight container in the refrigerator for up to 4 days. Allow them to cool completely before storing to prevent condensation.
Freezing: While possible, freezing isn’t recommended as mushrooms and onions can become mushy when thawed. If you must freeze, use them within 2 months and plan to incorporate them into cooked dishes rather than serving as a side.
Reheating Methods: The best way to reheat is in the air fryer at 350°F for 2-3 minutes to restore crispiness. Alternatively, reheat in a skillet over medium heat for 3-4 minutes, stirring frequently. Avoid microwaving as it will make them soggy.
Make-Ahead Tips: You can slice the vegetables up to 24 hours ahead and store them separately in the refrigerator. Season just before cooking for the best texture and flavor.
Frequently Asked Questions
Can I use frozen mushrooms and onions?
Fresh vegetables work best for this recipe. Frozen mushrooms and onions contain extra moisture that will prevent proper browning and create a soggy texture.
What’s the best mushroom variety to use?
Button, cremini, and baby bella mushrooms work excellently. You can also mix varieties for more complex flavor. Avoid delicate mushrooms like enoki or very large portobello caps.
How do I prevent the vegetables from drying out?
Don’t skip the oil – it’s essential for proper browning and preventing dryness. Also, avoid overcooking by checking frequently during the last few minutes.
Can I make this recipe vegan?
This recipe is naturally vegan when made with olive oil instead of butter. All the seasonings listed are plant-based.
Why are my mushrooms and onions soggy?
This usually happens from overcrowding the basket or not patting the mushrooms dry before cooking. Make sure vegetables are in a single layer and moisture is removed beforehand.
Can I add other vegetables to this recipe?
Yes! Bell peppers, zucchini, and cherry tomatoes work well. Add harder vegetables like carrots at the beginning and softer ones during the last few minutes.
