Air Fryer Bell Peppers And Onions - Quick, Flavorful, and Versatile
Ingredients
- 3 bell peppers (any colors you like), seeded and sliced into 1/2-inch strips
- 1 large yellow or red onion, peeled and sliced into 1/2-inch wedges
- 1–1.5 tablespoons olive oil (or avocado oil)
- 1 teaspoon kosher salt (start with less if using fine salt)
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1/2 teaspoon smoked paprika (optional, but great for depth)
- Pinch of red pepper flakes (optional, for gentle heat)
- Fresh lemon or lime for a finishing squeeze (optional)
- Fresh herbs like parsley or cilantro, chopped (optional)
Instructions
- Preheat the air fryer: Set it to 380°F (193°C). Preheating helps the veggies brown better.
- Prep the veggies: Slice peppers and onions into even strips, about 1/2-inch thick. Uniform pieces cook evenly.
- Season: In a large bowl, toss peppers and onions with oil, salt, pepper, garlic powder, and smoked paprika. Add red pepper flakes if you like a little heat.
- Load the basket: Spread the veggies in a loose, even layer. A bit of overlap is fine, but avoid packing too tightly. Work in batches if needed.
- Air fry: Cook for 10–13 minutes, shaking the basket halfway. Check at the 8-minute mark if your air fryer runs hot.
- Finish: When peppers are tender with light char on the edges, remove and hit them with a squeeze of lemon or lime. Sprinkle with fresh herbs if you’d like.
- Taste and adjust: Add a pinch more salt or a crack of pepper to finish.

FAQ
Do I need to line the air fryer basket?
Using a liner is optional. If you do, choose a perforated liner so air can circulate.
Avoid parchment that blocks airflow, or you’ll lose the char.
Can I use frozen peppers and onions?
Yes, but don’t thaw first. Toss with oil and seasonings, then cook a few extra minutes. Expect softer texture and less browning than fresh.
What oil works best?
Olive oil or avocado oil both work well.
You need just enough to coat lightly and help the spices stick.
How do I keep the onions from burning?
Slice onions a bit thicker than peppers and shake the basket halfway. If your air fryer runs hot, reduce temp to 370°F and add 1–2 minutes to the cook time.
Can I add mushrooms or zucchini?
Absolutely. Mushrooms cook at a similar rate.
Zucchini cooks faster, so slice it thicker or add it halfway through.
What should I serve these with?
Great with grilled chicken, fish, steak, sausages, tacos, grain bowls, eggs, and sandwiches. They also make a quick base for quesadillas.
How do I get more char?
Don’t crowd the basket, preheat, and bump the temp to 390°F for the last 2 minutes. Watch closely to avoid burning.
