Air Fryer Blackened Onion & Bell Pepper

Ingredients (Serves 2–3)

  • 1 large onion (yellow or red), sliced into 1/2-inch rings

  • 1 large bell pepper (any color), sliced into strips

  • 1–2 tbsp olive oil

  • 1 tsp smoked paprika

  • 1/2 tsp garlic powder

  • 1/2 tsp onion powder

  • 1/4 tsp cayenne pepper (optional, for heat)

  • 1/2 tsp salt (adjust to taste)

  • 1/4 tsp black pepper

  • 1 tsp lemon juice or balsamic vinegar (optional, for finishing)


👩‍🍳 Step-by-Step Instructions

1️⃣ Prep the Vegetables

  1. Peel and slice the onion into 1/2-inch rings or wedges.

  2. Wash and slice the bell pepper into strips.

  3. Pat dry with a paper towel to remove excess moisture (helps with roasting).


2️⃣ Season

  1. In a mixing bowl, combine olive oil, smoked paprika, garlic powder, onion powder, cayenne, salt, and black pepper.

  2. Toss the onion and bell pepper slices in the seasoning mixture until evenly coated.


3️⃣ Preheat Air Fryer

  • Preheat your air fryer to 380°F (193°C) for 3–5 minutes.


4️⃣ Air Fry the Vegetables

  1. Place onion and bell pepper slices in the air fryer basket in a single layer (avoid overcrowding).

  2. Cook at 380°F (193°C) for 12–15 minutes, shaking the basket halfway through.

  3. Check for tenderness and slight blackening at edges — the goal is a caramelized, slightly charred appearance.


5️⃣ Finish

  1. Optional: drizzle with lemon juice or balsamic vinegar for extra brightness.

  2. Taste and adjust salt and pepper.


🔥 Tips

  • Crispier edges: Cut veggies evenly and avoid overlapping.

  • Extra smoky flavor: Add 1/2 tsp smoked paprika or a light brush of soy sauce before cooking.

  • Spice variation: Sprinkle chili flakes or a dash of cumin for a different flavor profile.

  • Meal prep: Cooked onion and peppers can be stored in an airtight container in the fridge for 3–4 days and reheated in the air fryer for 3–5 minutes.


✅ Serving Ideas

  • Serve as a side with grilled chicken or steak.

  • Toss into fajitas or wraps with protein.

  • Mix with cooked rice or quinoa for a quick Mediterranean bowl.

  • Top pizzas or flatbreads for extra roasted flavor.
