Ingredients for Cheesy Roasted Broccoli

You only need a handful of ingredients to make this flavorful dish:

• Broccoli florets (1 lb) — fresh or frozen (thaw and pat dry if frozen).
• Olive oil (2 tbsp) — helps the florets crisp.
• Cheddar cheese (shredded, ½ cup) — sharp cheddar adds the best flavor.
• Garlic powder (½ tsp) — for a subtle savory note.
• Salt — to taste.

Step-by-Step Instructions

1. Preheat Oven or Air Fryer

Preheat the oven to 425°F (220°C). If using an air fryer, preheat to 400°F (200°C). High heat helps the broccoli develop crisp, caramelized edges.

2. Prepare the Broccoli

Rinse broccoli under cold water and pat dry with a kitchen towel or paper towels. Dry florets roast instead of steam. Cut into bite-sized pieces. If using frozen broccoli, thaw completely and blot dry.

3. Season the Broccoli

In a large bowl, toss the florets with olive oil, garlic powder, and a generous pinch of salt until evenly coated.

4. Roast the Broccoli

Spread the broccoli in a single layer in a casserole dish or on a rimmed baking sheet. Avoid crowding so the florets roast evenly. In the oven, roast for 15 minutes until bright green and slightly charred at the edges.

5. Add the Cheese

Remove the tray, sprinkle shredded cheddar evenly over the broccoli, and return it to the oven for 5–7 minutes until the cheese melts and becomes gooey.

6. Serve Immediately

Transfer to a serving dish and enjoy hot as a side or a snack.

Air Fryer Method

The air fryer is a quick, low-oil alternative that yields crisp results.

Instructions for Air Frying:

1. Preheat the air fryer to 400°F (200°C).
2. Toss broccoli with olive oil, garlic powder, and salt.
3. Arrange in a single layer in the basket.
4. Cook for 10 minutes, shaking once halfway through.
5. Sprinkle cheddar on top and cook 2–3 more minutes until melted.
6. Serve hot.

Tips for the Best Cheesy Roasted Broccoli

• Use Fresh Cheese: Shred cheddar from a block; it melts smoother than pre-shredded varieties.
• Adjust Cooking Time: Smaller florets cook faster—watch to avoid overcooking.
• Try Other Cheeses: Parmesan, mozzarella, or blends change the flavor profile.
• Add Heat: Red pepper flakes or a pinch of cayenne add a spicy kick.
• Brighten with Lemon: A squeeze of fresh lemon just before serving lifts the flavors.

Serving Suggestions

Cheesy roasted broccoli pairs well with many mains and can also stand alone. Try these ideas:

• Serve with grilled chicken, steak, or salmon for a balanced plate.
• Mix into pasta or serve with rice for a hearty vegetarian meal.
• Use as a topping for baked potatoes or as a filling for wraps and sandwiches.

Storing and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 375°F (190°C) oven for 5–7 minutes or in an air fryer at 350°F (175°C) for a few minutes to restore crispness.

Nutritional Highlights

This dish delivers vitamins, fiber, and antioxidants from broccoli, healthy fats from olive oil, and calcium and protein from cheddar—an enjoyable and nourishing side.
