If you’ve ever sat down at LongHorn Steakhouse and thought, “Why is this broccoli so insanely good?” — you’re not alone. Their Garlic Parmesan Broccoli has achieved cult-favorite status for a reason. Perfectly tender-crisp florets, roasted until lightly charred, tossed in buttery garlic goodness, and finished with a generous coating of savory Parmesan cheese.

This Copycat LongHorn Garlic Parmesan Broccoli recipe recreates that exact steakhouse experience at home — no reservations required. It’s bold, aromatic, crispy at the edges, and unapologetically cheesy, yet still feels fresh and balanced.

What sets this broccoli apart from ordinary roasted vegetables is layered flavor. Instead of dumping everything on at once, this method builds taste step by step: roasting first for texture, finishing with garlic butter for richness, and finally showering with Parmesan so it melts and clings to every floret.

Whether you’re serving it alongside steak, chicken, seafood, or even piling it onto pasta, this broccoli refuses to be “just a side dish.” It steals the spotlight.

Why This Broccoli Recipe Works So Well

Simple ingredients, bold payoff

Ingredients

4 cups fresh broccoli florets
3 tablespoons olive oil
½ teaspoon salt
½ teaspoon black pepper
½ teaspoon garlic powder
3 tablespoons unsalted butter
4 cloves garlic, minced
½ cup freshly grated Parmesan cheese
Optional: red pepper flakes for heat

Instructions

Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
Place broccoli florets in a large bowl. Drizzle with olive oil and season with salt, pepper, and garlic powder. Toss well to coat evenly.
Spread broccoli in a single layer on the prepared baking sheet.
Roast for 18–22 minutes, flipping halfway, until edges are crispy and centers are tender.
While broccoli roasts, melt butter in a small skillet over medium heat.
Add minced garlic and sauté for 30–45 seconds until fragrant (do not brown).
Remove broccoli from oven and immediately drizzle with garlic butter.
Sprinkle Parmesan cheese over hot broccoli and toss gently.
Return to oven for 3–5 minutes until cheese melts.
Serve immediately while hot and crispy.

The Secret to Steakhouse-Style Texture

The key is high heat roasting. Broccoli needs intense oven heat to evaporate surface moisture quickly, creating crispy caramelized edges. Crowding the pan will cause steaming instead — so always use a large sheet pan and spread florets evenly.

Flavor Boosting Tips

Use freshly grated Parmesan, not pre-shredded
Roast on the top oven rack for extra crispness
Finish with lemon zest for brightness
Add crushed red pepper for subtle heat
