Air Fryer Peppers and Mushrooms
This beautifully charred Air Fryer peppers and mushrooms recipe is like a custom-made piece of art when they come out of the air fryer. With added sweet Vidalia onions, I love how they perfectly cook together and turn soft, juicy, and golden; with crispy edges and gorgeous caramelized skins.
Not only can you get mushrooms and peppers crispy and delicious in the air fryer, but you can also avoid all the oil that comes with pan frying. Air frying helps to keep the vibrant color and flavor of bell peppers while lightly seasoning them. More of my taste buds’ dancing favorites sides are Air fryer Mushrooms and Onions, Potatoes and Onions, and Lipton Potatoes.
Ingredients
- Peppers: I used green and red Bell peppers for this recipe. And two small Jalapenos.
- Mushrooms: pick an 8 oz package of Baby Bella, Shitake or white button mushrooms.
- Onions: Use sweet, Vidalia onions, yellow or red onions. I love adding onions for an extra kick of flavor! Their crisp, sweet taste enhances the savory notes of the peppers and mushrooms and makes the overall dish truly delectable. Plus, when cooked together, the colors are visually tantalizing and lend a real depth of flavor in one bite.
- Oil: Use 1 Tablespoon of Avocado oil or Extra Virgin Olive oil.
- Salt and pepper to taste.
- Seasoning of choice. I used half a teaspoon of Vegeta All-purpose seasoning.
How to cook Mushrooms, Peppers, and Onions in the Air fryer
Chef Gordon Ramsay swears by it! He says the result is even better than deep frying this combination of veggies. With just a little dash of seasoning and a few minutes in the air fryer per side, you’ll be ready to enjoy this classic side with a crispy twist.
- Preheat your air fryer to 390°F (195° Celsius).
- Wash peppers and pat them dry.
- Cut each pepper in half and remove the seeds. Then cut it into 1-inch strips or squares.
- Slice onion in half, then thinly slice into half-circles.
- Rinse mushrooms and pat them dry. Cut each mushroom in half, or into quarters for larger mushrooms.
- In a large bowl add sliced peppers, mushrooms, onions, oil, salt & pepper to taste and season.
- Toss them all together until fully coated.
- Transfer veggies to the air fryer basket/tray, and lay them in a single layer.
- Air fry them for 10 to 15 minutes (toss them every five minutes so that they cook evenly from each side). I did mine for 13 minutes total and the veggies came out charred with gorgeous crispy skin.
- Fry them until their desired color and crispiness.
- When done, the onions should be translucent. Peppers should be golden brown with slightly charred skins. Mushrooms should be dark brown in color, slightly wrinkly on the outside, and juicy on the inside.
Make it a Meal
Air fryer roasted peppers and mushrooms are an easy and versatile ingredient that can be used in almost any dish. I love adding them to salads, sandwiches, tacos or pies. Are you looking for something lighter than the usual soup or stew for a main course? May I suggest trying roasted peppers and mushrooms with:
Air fryer Ribye for a delicious low-carb meal
Air-fried Hot Dogs with Crispy Buns
Mushroom and Onion Grilled Cheese
Leftovers
Store roasted capsicum peppers and mushrooms in an airtight container in the fridge for up to 5 days.
Freeze cooked peppers & mushrooms in a ziplock bag for up to three months. Reheat in an air fryer for 2-3 minutes to bring back the outer crisp.
Recipe Tips and Variations
- Use fresh, firm bell peppers and mushrooms that are in season. Avoid over-ripe vegetables, as they may become mushy and won’t hold their shape when air-fried.
- Ensure that peppers and mushrooms are cut into evenly-sized pieces (1-inch slices) so that they cook evenly.
- Don’t overcrowd the basket. Allow the vegetables to have space to cook evenly.
- To change things up, sprinkle some Parmesan cheese over mushrooms and peppers for an extra savory kick.
- Make them spicy: Add smoked paprika, a little chili powder or cayenne pepper.
Do Vegetables Shrink in the Air Fryer?
Yes! Like shrunken clothing after an accidental tumble in the washing machine! All three – mushrooms, peppers, and onions – belong to a genus of vegetables known as Allium which have high levels of moisture that can be lost when cooked. So whether you’re air frying these veggies, sauté, boil or fry them; they may look aesthetically pleasing but don’t forget that no matter what cooking method you choose they will eventually turn into a fraction of their original size.
For this reason, I always double my recipe when air-frying peppers and mushrooms. This recipe makes 6-8 servings. The freshly cut veggies may not fit in your air fryer at once, so you may need to cook them in batches. It is still so worth the effort. I cooked in two batches in my Ninja Foodi air fryer.
