2 cups broccoli florets (small pieces)

1 carrot, thinly sliced or diced

1/2 red bell pepper, chopped

1/2 yellow onion, finely chopped

1/2 zucchini, diced (optional)

1/2 tsp dried thyme or Italian seasoning

Topping:

1/2 cup breadcrumbs (Panko or regular)

1 tbsp olive oil or melted butter

2 tbsp grated Parmesan (optional)

 Instructions:

Pre-Cook Vegetables

To ensure tenderness, lightly steam the broccoli, carrots, and zucchini for 3–4 minutes. You can also microwave them with a tablespoon of water, covered, for about 3 minutes.

Prepare the Cheese Sauce

In a saucepan or microwave-safe bowl:

Melt butter, whisk in flour to form a roux.

Slowly add milk, stirring constantly to avoid lumps.

Add cheddar, Parmesan, thyme, salt, and pepper.

Cook until thick and creamy (about 3–5 minutes).

Combine Everything

In a large bowl, mix steamed vegetables, chopped bell pepper, onion, and garlic.

Pour the cheese sauce over the veggies and mix to coat evenly.

Assemble in a Baking Dish

Use a 7-inch round or square baking dish that fits your air fryer.

Spoon in the mixture and level it out.

In a small bowl, mix breadcrumbs with oil or melted butter and sprinkle on top of the casserole.

Air Fry

Preheat air fryer to 350°F (175°C) for 3 minutes.

Place dish in the air fryer basket.

Cook for 20–25 minutes, or until the top is golden and the casserole is bubbly.

Check at 15 minutes — if browning too fast, lightly cover with foil.

Cool & Serve

Let it rest for 5 minutes before serving.

Garnish with fresh parsley or chives if desired.

 Optional Add-ins:

1/2 cup cooked quinoa or rice (for extra heartiness)

1/2 cup cooked shredded chicken or chickpeas for protein

Dash of hot sauce or mustard in the cheese sauce for kick
