How to Make Garlic Parmesan Roasted Broccoli with Lemon and Red Pepper Flakes Recipe
Step 1: Preheat the Oven
Start by setting your oven to 400°F (200°C). This temperature is ideal for roasting broccoli, unlocking its natural sweetness while creating those irresistible crispy edges.
Step 2: Prepare the Broccoli
Wash and cut the broccoli into evenly sized florets. Uniform pieces ensure they all cook evenly, giving you tender stems with perfectly crisp tips every time.
Step 3: Season the Broccoli
In a large bowl, toss the broccoli with olive oil, minced garlic, salt, and pepper. This simple coating makes sure every floret is infused with flavor and roasted to perfection.
Step 4: Roast the Broccoli
Arrange the broccoli in a single layer on a baking sheet to ensure they roast evenly. Roast in the preheated oven for 20-25 minutes, tossing halfway through. You’ll notice the broccoli turning golden with edges that are satisfyingly crisp.
Step 5: Add the Parmesan
Remove the tray from the oven and immediately sprinkle the grated Parmesan cheese over the hot broccoli. Toss gently to let the cheese melt and form a lovely coating that adds richness and depth.
Step 6: Finish with Lemon and Red Pepper Flakes
For that iconic burst of brightness, drizzle fresh lemon juice and sprinkle lemon zest over the roasted broccoli. If you enjoy a touch of heat, sprinkle red pepper flakes on top to add a deliciously subtle spice.
Step 7: Serve Immediately
Serve your Garlic Parmesan Roasted Broccoli with Lemon and Red Pepper Flakes Recipe while it’s hot. Its vibrant colors and irresistible smell make it a star side dish perfect for any occasion.

FAQs

Can I prepare this recipe for a larger crowd?
Yes, simply multiply the ingredients as needed and roast in batches if your baking sheet becomes crowded, ensuring even cooking and crisp edges every time.
What can I do if I don’t have Parmesan cheese?
You can substitute with Pecorino Romano or a sharp Asiago for similar salty, nutty notes. Nutritional yeast also works as a dairy-free alternative with a cheesy flavor.
