Sliced red onion layers, translucent with browned edges, add depth, mixed with segments of roasted garlic cloves showing light golden skin. Fresh green thyme sprigs are sprinkled on top, adding a touch of vibrant green to the warm colors.

1 sweet potato, roughly chopped
1 red pepper, roughly chopped
2 red onions, cut into 8 wedges each
200g Jersey Royals or baby potatoes

A few thyme sprigs
1 tbsp olive oil

Instructions

Step 1: Place all the chopped vegetables, garlic, and thyme sprigs into the air fryer basket. Drizzle the olive oil over them.
Step 2: Shake the basket well to ensure all the vegetables are evenly coated with olive oil and herbs.
Step 3: Roast the vegetables at 200°C (392°F) for 20 minutes.
Step 4: After 20 minutes, shake the basket again to turn the vegetables for even cooking.

Tips & Variations

Try adding other root vegetables like carrots or parsnips for extra variety and flavor.
Use dried herbs such as rosemary or oregano if fresh thyme is unavailable.
For a smoky twist, sprinkle smoked paprika over the vegetables before cooking.
Make sure to cut the vegetables into similar sizes to ensure even cooking.

Storage

Store leftover roasted vegetables in an airtight container in the refrigerator for up to 3 days. Reheat gently in the air fryer or oven at low temperature until warmed through to maintain their texture.

How to Serve

FAQs

Can I use frozen vegetables for this recipe?

While fresh vegetables give the best texture, you can use frozen vegetables. Adjust the cooking time slightly and check for tenderness as frozen vegetables may release more moisture.

What temperature should I set my air fryer to?

Set your air fryer to 200°C (392°F) as this temperature helps to roast the vegetables evenly and caramelize their natural sugars for more flavor.

Ingredients

Scale

Vegetables

1 small butternut squash, roughly chopped
1 sweet potato, roughly chopped
1 red pepper, roughly chopped
2 red onions, cut into 8 wedges each
200g Jersey Royals or baby potatoes

Seasonings

2–4 garlic cloves, lightly bashed
A few thyme sprigs
1 tbsp olive oil

Instructions

Prepare the Vegetables: Roughly chop the butternut squash, sweet potato, and red pepper. Cut each red onion into 8 wedges. Rinse and dry the Jersey Royals or baby potatoes.
Season the Vegetables: Place all the chopped vegetables, garlic cloves, and thyme sprigs in the air fryer basket. Drizzle with 1 tablespoon of olive oil and shake or toss thoroughly to coat all pieces evenly in the oil and aromatics.
Initial Roasting: Roast the vegetables in the air fryer at 200°C (392°F) for 20 minutes. This will start the cooking process and allow the veggies to soften and pick up a roasted flavor.
Shake and Continue Roasting: After the first 20 minutes, shake the basket to turn the vegetables for even cooking. Roast again at 200°C for an additional 10 to 20 minutes until all the vegetables are tender and golden brown. The total roasting time should be between 30 and 40 minutes depending on your air fryer and vegetable size.

Notes

You can experiment with other vegetables such as carrots or parsnips for variation.
Use fresh thyme sprigs for the best aroma; dried thyme can be substituted but use sparingly.
Adjust cooking time based on the size of vegetable pieces and your air fryer model to avoid burning or undercooking.
Serve hot as a side dish or toss with salad greens for a warm vegetable salad.
