Why You’ll Love This Copycat Longhorn Garlic Parmesan Broccoli

It’s not just broccoli—it’s indulgent, comforting, and loaded with flavor. The velvety garlic Parmesan sauce clings to every floret, making even the pickiest eaters come back for seconds. It’s quick to make, doesn’t require hard-to-find ingredients, and elevates any meal into something that feels restaurant-worthy without the restaurant price tag.

What Kind of Broccoli Should I Use?

Fresh broccoli florets work best for this recipe. You want vibrant green heads with tight buds and firm stalks. While frozen broccoli can be used in a pinch, it tends to retain more moisture, which may dilute the creamy sauce. For optimal texture and flavor, I recommend steaming or blanching the fresh florets just until tender but still bright green.

Options for Substitutions

If you’re out of Parmesan, Pecorino Romano or Asiago can step in nicely. You can also swap heavy cream for half-and-half if you want a slightly lighter sauce. Not a fan of garlic? Try roasted shallots for a milder, sweeter flavor. And if you’re dairy-free, a plant-based cream and vegan cheese can also make this recipe work without compromising too much on taste.

Ingredients for this Copycat Longhorn Garlic Parmesan Broccoli

Broccoli Florets – The star of the show. Choose fresh, firm, and dark green broccoli for the best texture and flavor. Trimmed into bite-sized pieces for even cooking.

Garlic – Fresh garlic cloves bring bold aroma and deep flavor. Sautéing it enhances its sweetness and cuts the raw bite.

Heavy Cream – This gives the sauce its luxurious, velvety base. It clings to the broccoli and creates that indulgent restaurant-style finish.

Parmesan Cheese – Freshly grated Parmesan melts into the sauce, adding salty, nutty richness that’s signature to this dish.

Butter – Used for sautéing the garlic and starting the sauce. It also contributes a silky texture and depth.

Salt & Black Pepper – Essential for balancing and enhancing all the other flavors. Use freshly ground pepper for a bit of bite.

Red Pepper Flakes (optional) – A pinch adds subtle heat and complexity.

Lemon Zest (optional) – Adds brightness and contrast to the creamy richness, making the dish more dynamic.

Step 1: Steam or Blanch the Broccoli

Bring a large pot of salted water to a boil. Add broccoli florets and cook for 2–3 minutes until vibrant green and just tender. Immediately transfer them to an ice bath or rinse under cold water to stop the cooking. Drain thoroughly.

---

Step 2: Sauté the Garlic

In a large skillet over medium heat, melt the butter. Add the minced garlic and sauté for about 30 seconds to 1 minute, just until fragrant and golden. Be careful not to burn it—it should be aromatic, not bitter.

---

Step 3: Make the Parmesan Cream Sauce

Pour in the heavy cream and let it simmer for 2–3 minutes, stirring occasionally, until it slightly thickens. Add the grated Parmesan and stir until completely melted and smooth. Season with salt, black pepper, and a pinch of red pepper flakes if using.

---

Step 4: Combine Broccoli with the Sauce

Add the cooked and drained broccoli into the skillet. Toss gently to coat every floret in the creamy garlic Parmesan sauce. Cook for another 1–2 minutes just to warm everything through.

---

Step 5: Finish and Serve

Sprinkle a little extra Parmesan on top and finish with freshly ground black pepper and lemon zest if desired. Serve immediately while hot and creamy.

How Long to Prepare the Copycat Longhorn Garlic Parmesan Broccoli

Prep Time: The hands-on prep is minimal—about 10 minutes tops. That includes trimming the broccoli, mincing the garlic, and grating the Parmesan. If you buy pre-cut broccoli and pre-grated cheese, you’ll cut that time in half.

Cook Time: Steaming or blanching the broccoli takes 3 minutes, and the sauce comes together in about 7–8 minutes. The entire dish can be completed in under 20 minutes, making it ideal for busy weeknights or quick meal prep.

Tips for Perfect Copycat Longhorn Garlic Parmesan Broccoli

• Use fresh garlic and freshly grated Parmesan for the most authentic and intense flavor.
• Don’t overcook the broccoli. It should be tender but still vibrant and slightly crisp.
• Let the sauce thicken slightly before adding the cheese to prevent clumping.
• Toss the broccoli gently to avoid breaking the florets.
• Taste as you go—a little extra Parmesan or salt can make a big difference.

Watch Out for These Mistakes While Cooking

• Overcooking the broccoli turns it mushy and dulls its bright green color.
• Burning the garlic—it goes from golden to bitter in seconds.
• Using low-quality Parmesan can lead to a grainy or bland sauce.
• Skipping the salt in the blanching water can result in under-seasoned broccoli.
• Adding cheese to boiling cream instead of a simmer can cause separation.

Freezing: This dish isn’t ideal for freezing as the sauce can separate upon reheating. However, if necessary, freeze for up to 1 month and reheat slowly while whisking in a splash of cream to bring the sauce back together.

Frequently Asked Questions

How do I keep the sauce from getting grainy?

Use freshly grated cheese and add it slowly to a warm—not boiling—cream base. Stir constantly until smooth.

Can I make this dish ahead of time?

Is there a way to make it lighter?

Swap the heavy cream with half-and-half or whole milk and use less butter and cheese.

Can I add protein to make it a full meal?

Absolutely. Grilled chicken, shrimp, or even tofu can be added to bulk it up into a main dish.
