Step-by-Step Instructions

Step 1: Cut for even cooking

Cut potatoes into ~1-inch cubes and onions into ¼-inch slices. Pat potatoes dry with a towel.
Tip: Drier potatoes = better browning and crisp edges.

Step 2: Season to coat

In a medium bowl, add potatoes, onions, 1–2 Tbsp oil, salt, pepper, garlic powder, and your seasoning blend. Toss until everything glistens and the spices are evenly distributed.
Tip: Lightly oil—too much can soften the crust.

Step 3: Preheat the air fryer

Preheat to 375°F (190°C). A hot basket jump-starts crisping and prevents sticking.
Tip: If your model doesn’t have preheat, run it empty for 3 minutes.

Step 4: Air fry in a single layer

Transfer potatoes and onions to the basket in a single layer. Air fry 12–15 minutes, tossing every 5 minutes so edges brown evenly.
Tip: Cooking a bigger batch? Work in 2 rounds rather than crowding.

Step 5: Add rosemary to finish

During the last 5 minutes, sprinkle in 1 Tbsp chopped fresh rosemary and toss. Continue air frying until the potatoes are deeply golden and onions are tender-caramelized.
Tip: Taste and adjust salt/pepper before serving.

Healthier Alternatives

• Swap the spud: Try sweet potatoes for extra beta-carotene; cut to ¾-inch and cook 1–2 minutes longer.
• Extra protein: Toss with chickpeas in the last 7–8 minutes (drained/dried) for a hearty bowl.
• Heat lovers: Add ½ tsp smoked paprika or ¼ tsp chili flakes with the dry spices.

Serving Suggestions for Air Fryer Potatoes and Onions

Common Mistakes to Avoid (Air Fryer Potatoes and Onions)

• Overcrowding the basket: Steams instead of crisps. Fix: Cook in batches; keep to one layer.
• Skipping the preheat: Leads to pale results. Fix: Heat to 375°F/190°C for 3 minutes first.
• Inconsistent cuts: Uneven cooking. Fix: Keep potatoes near 1 inch and onions ¼ inch.
• Too much oil: Soft, greasy edges. Fix: 1–2 Tbsp is plenty for two potatoes.
• Not tossing: Patchy browning. Fix: Shake every 5 minutes for even color.

Storing Tips

• Refrigerate: Airtight container 3–4 days.
• Reheat (best): Air fryer 350°F (175°C), 4–6 minutes until re-crisped.
• Skillet option: Warm in a nonstick pan with a teaspoon of oil to revive crunch.
• Freezing? Not ideal—potatoes can turn mealy. If needed, freeze flat and re-crisp longer in the air fryer.

FAQs

Q1. Which potatoes work best?

Russet crisp the most; Yukon Gold give creamy centers. Red potatoes work too—cut slightly smaller for similar timing.

Q2. Can I add bell peppers or mushrooms?

Yes. Add bell peppers at the start (same size as onions). Add mushrooms in the last 7–8 minutes so they don’t steam.

Q3. How do I keep onions from burning?

Slice to ¼ inch and toss every 5 minutes. If your model runs hot, drop to 360°F (182°C) for the final minutes.

Q4. Can I make this oil-free?

Yes—use a light water or broth mist and a nonstick basket. Expect slightly less browning; extend cook time 1–2 minutes.

Q5. My potatoes aren’t crisp—what went wrong?

Likely crowding or excess moisture. Dry the cubes well, preheat, cook in a single layer, and don’t exceed 2 Tbsp oil for this quantity.
