If you’ve ever wondered how to roast bell peppers in an air fryer, this guide will walk you through the process step by step, no fancy skills, no messy ovens, and no guesswork.
Using an air fryer is one of the fastest, most energy‑efficient, and foolproof ways to roast bell peppers at home. Whether you’re meal prepping, cooking for one, or just trying to add more veggies to your meals, this method delivers consistent, restaurant‑quality results every time.
Why Learn How to Roast Bell Peppers in an Air Fryer
The common problem
Many home cooks struggle with:
- Soggy peppers instead of caramelized ones
- Burnt skins but raw insides
- Oven roasting that takes too long or heats up the kitchen
Why the air fryer works so well
The air fryer uses rapid hot air circulation, which:
- Roasts peppers evenly on all sides
- Creates blistered, lightly charred skin without overcooking
- Cuts cooking time by nearly half compared to an oven
As a kitchen professional and cooking educator, I recommend air fryer roasting as the most beginner‑friendly method, minimal prep, predictable results, and easy cleanup.
Why This Method Works (The Simple Science Behind It)
Roasting bell peppers is all about dry heat + airflow.
Here’s what’s happening inside your air fryer:
- High heat (375–400°F) breaks down cell walls in the peppers
- Natural sugars caramelize, enhancing sweetness
- Hot air circulates constantly, preventing steaming
- Moisture evaporates quickly, giving you tender flesh with lightly charred edges
Unlike pan‑roasting or baking, the air fryer doesn’t trap steam—this is the key to achieving that classic roasted pepper flavor.
What You’ll Need
Essential Ingredients
- Fresh bell peppers (red, yellow, orange, or green)
- Olive oil (or avocado oil)
- Salt (kosher or sea salt)
Optional Add‑Ins
- Freshly ground black pepper
- Garlic powder or smoked paprika
- Italian seasoning or dried herbs
Tools
- Air fryer (basket or oven‑style)
- Cutting board
- Sharp knife
- Tongs
- Bowl for tossing
Substitutes & Notes
- No olive oil? Use avocado, grapeseed, or canola oil
- Any color bell pepper works (red is sweetest, green is more savory)
Steps to Roast Bell Peppers in an Air Fryer
Step 1: Wash and Dry the Peppers
Rinse bell peppers thoroughly under cool water. Dry completely with a towel—excess moisture prevents proper roasting.
Pro tip: Dry peppers roast, wet peppers steam.
Step 2: Cut the Peppers
You have two options:
Option A: Halves or Quarters (Best for Meal Prep)
- Cut off the stem
- Slice in half or quarters
- Remove seeds and white ribs
Option B: Strips (Best for Bowls & Fajitas)
- Slice into even strips, about ½ inch wide
Try to keep pieces uniform so they cook evenly.
Step 3: Season Lightly
Place peppers in a bowl and toss with:
- 1–2 teaspoons oil per pepper
- A pinch of salt
Avoid over‑oiling—air fryers need less oil than ovens.
Step 4: Preheat the Air Fryer
Preheat to 380°F (193°C) for 3–5 minutes.
Preheating ensures:
- Faster blistering
- Better caramelization
- Even cooking from the start
Step 5: Arrange in the Basket
- Place peppers in a single layer
- Skin‑side up if using halves
- Avoid overcrowding (cook in batches if needed)
Step 6: Air Fry
Roast at 380°F for 10–14 minutes, shaking or flipping halfway.
Cooking time guide:
- Strips: 8–10 minutes
- Quarters: 10–12 minutes
- Large halves: 12–14 minutes
You’re looking for:
- Blistered skin
- Soft, tender flesh
- Light char on the edges
Step 7: Optional – Steam for Easy Peeling
If you want skinless roasted peppers:
- Transfer hot peppers to a bowl
- Cover loosely with foil or a plate
- Let steam for 10 minutes
- Peel skin off easily with fingers
Pro Tips & Best Practices
Choose the Right Peppers
- Red, orange, yellow: sweeter, ideal for roasting
- Green: more bitter but still delicious when charred
Don’t Skip the Oil
A light oil coating:
- Prevents drying out
- Encourages browning
- Helps seasoning stick
Shake or Flip Once
This ensures even roasting and prevents hot spots.
Mistakes to Avoid
- Overcrowding the basket
- Using too much oil
- Cooking at low temperatures
- Skipping preheating

Common Questions
- Can you roast whole bell peppers in an air fryer?
Yes, but it’s less efficient. Whole peppers take longer (18–22 minutes) and roast less evenly. Cutting them improves airflow and texture.
- What temperature is best for air fryer roasted bell peppers?
The ideal temperature is 375–400°F. This range blisters the skin without burning the flesh.
- Do I need to peel roasted bell peppers?
Not always. The skin is edible, but peeling improves texture for sauces, dips, and spreads.
- How do I store roasted bell peppers?
Store in an airtight container:
- Refrigerator: up to 5 days
- Freezer: up to 3 months (best peeled)
- Can I roast frozen bell peppers in an air fryer?
Yes, but expect softer texture. Cook at 400°F for 10–12 minutes and drain excess moisture afterward.
- Are air fryer roasted bell peppers healthy?
Absolutely. They’re:
- Low‑calorie
- Rich in vitamin C and antioxidants
- Made with minimal oil
When NOT to Use This Method
Avoid air fryer roasting if:
- You need large batches at once
- Your peppers are heavily marinated (excess liquid causes steaming)
- You want deep, fire‑roasted smokiness (grill is better)
Alternative Methods to Roast Bell Peppers
