This sirloin steak with garlic butter is a true showstopper. The tender, juicy beef is grilled to perfection, then finished with a garlicky butter that melts right into the meat, giving it a rich, savory flavor. I find it hard to imagine another steak recipe that comes close to how delicious this one tastes.

Why You’ll Love This Recipe

I love how simple yet impressive this steak is. The garlic butter takes almost no time to prepare, yet it transforms the dish into something that feels restaurant-worthy. I also like that I can grill the steak outdoors in summer or use a hot skillet indoors when it’s too cold. This recipe is versatile, straightforward, and always a crowd-pleaser.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

½ cup butter
4 cloves garlic, minced
2 teaspoons garlic powder
4 pounds beef top sirloin steaks
salt and pepper to taste

Directions

1. I start by preheating my grill on high heat and lightly oiling the grate.

2. While the grill heats, I melt the butter in a small saucepan over medium-low heat.

3. I stir in the minced garlic and garlic powder, then set it aside.

4. I season both sides of the steaks generously with salt and pepper.

5. I place the steaks on the hot grill and cook them for about 4 to 5 minutes per side, until an instant-read thermometer inserted in the center reads 140°F (60°C) for medium doneness.

6. I transfer the steaks to warm plates, brush them liberally with the garlic butter, and let them rest for 2 to 3 minutes before serving.

Servings and timing

This recipe makes 8 servings. The prep time takes about 20 minutes, cooking takes 10 minutes, and the total time is roughly 30 minutes.

Variations

I sometimes swap the sirloin for filet mignon or ribeye if I want something extra tender. I also like to add fresh herbs like parsley or chives to the garlic butter for a fresher flavor. If I don’t have a grill available, I sear the steaks in a cast-iron skillet and finish them in a hot oven. For a little extra kick, I mix in a pinch of red pepper flakes with the butter.

storage/reheating

If I have leftovers, I store the steak in an airtight container in the fridge for up to 3 days. To reheat, I prefer warming the steak gently in a skillet over low heat so it stays juicy. I don’t recommend microwaving, as it tends to dry the meat out.

FAQs

Can I use margarine instead of butter?

Yes, I can use margarine, but I find real butter gives the steak a richer, more authentic flavor.

How do I make the steak medium-rare instead of medium?

I cook it for about 3 to 4 minutes per side and check with a thermometer until it reaches 130°F (54°C).

Can I make this garlic butter ahead of time?

Yes, I often prepare the butter in advance and keep it in the fridge. It firms up nicely and can be sliced over hot steaks.

What sides go well with this steak?

I like serving it with baked potatoes, roasted vegetables, or a crisp green salad. Garlic bread is also a great addition.

Can I freeze the cooked steak?

Yes, I can freeze cooked steak for up to 2 months. I wrap it tightly in foil and store it in a freezer bag. When reheating, I thaw it in the fridge overnight and warm it gently.

Conclusion

This sirloin steak with garlic butter is one of my favorite ways to make a steak feel special without spending hours in the kitchen. I love how the garlic butter elevates the beef and how easy it is to prepare for a family dinner or special occasion. Every bite is rich, juicy, and bursting with flavor, and it’s a recipe I know I’ll make again and again.
