Seared Sirloin Steak In Garlic Herb Sauce Recipe Ingredients

To make this recipe, we will need the following ingredients:

  • 1 1/2–2 lb sirloin steak (top sirloin preferred), 1–1 1/4-inch thick: The star of the dish—top sirloin has great beefy flavor at a friendlier price. This thickness is ideal for getting a deep sear while keeping the center juicy.
  • 1 tsp kosher salt (plus more to taste): Seasons the steak all the way through and helps you get a better crust by drawing a little moisture to the surface, then allowing it to evaporate during searing.
  • 1/2 tsp black pepper: Adds gentle heat and bite that complements the richness of butter and beef.
  • 1 tbsp olive oil (or avocado oil): Provides a high-heat fat for searing so you can build a crust without burning the butter too early (avocado oil is especially good for higher smoke point).
  • 1 small yellow onion, diced: Adds sweet-savory depth and a little texture—when it cooks in the steak drippings and butter, it becomes glossy, slightly caramelized, and perfect spooned over the sliced steak.
  • 3 tbsp butter: Brings rich flavor and helps create a buttery pan sauce for basting; also carries the garlic and herbs so their flavor coats the steak.
  • 4 cloves garlic, minced: The signature flavor—sharp and aromatic, it perfumes the butter and creates that bold “steakhouse garlic butter” finish (added late so it doesn’t burn and turn bitter).
  • 1 tsp fresh thyme (or 1/2 tsp dried) (optional): Adds a subtle earthy, savory note that makes the garlic butter taste more complex and classic.
  • 1 tsp fresh rosemary, chopped (or 1/2 tsp dried) (optional): Adds a piney, steakhouse-style aroma that pairs especially well with beef and butter (a little goes a long way).
  • 1 tbsp chopped parsley (optional, for serving): Brightens the dish and adds fresh color, balancing the richness of the butter.
  • Lemon wedges (optional, for serving): A squeeze of acidity wakes up all the flavors, cuts through the richness, and makes the steak taste even beefier and fresher.

Garlic Herb Compound Butter (for serving)

  • 4 tbsp unsalted butter, softened: The creamy base that melts luxuriously over the hot steak; using unsalted lets you control seasoning and avoid an overly salty finish.
  • 1 clove garlic, finely grated or minced: Adds concentrated garlic punch directly in the finishing butter for maximum aroma and flavor.
  • 1 tbsp parsley, finely chopped: Fresh, clean flavor that lightens the compound butter and keeps it from tasting too heavy.
  • 1 tsp fresh thyme (or 1/2 tsp dried): Reinforces that classic herb-butter flavor and ties the finishing butter to the herbs used in the pan (if you add them).
  • 1 tsp lemon zest (optional): Adds bright citrus oils (more aromatic than juice) that make the butter taste fresh and “steakhouse.”
  • Pinch of salt + pepper: Seasons the compound butter so it tastes finished and punchy; pepper adds a tiny bit of heat and complexity as it melts.

Steps to Sear Sirloin Steak in Garlic Herb Sauce

Once you’ve gathered your ingredients, we will use the following process:

Two raw sirloin steaks are being cooked in a black cast iron skillet, promising the flavor and tenderness of the best sirloin steak.

Sear Steak

Preheat a heavy pan for best results – add generously seasoned steak to scorching hot pan, and cook with the fan on over the stove until one side is well charred.

Two pieces of sirloin steak are searing in a black cast iron skillet, with visible browning and some smoke rising around them—capturing the essence of the best sirloin steak cooking experience.

Flip

Flip steak to char underside.

Add Butter and Herbs

Add butter and herbs to pan.

Baste in Butter

Finish with Herbs and Garlic

In last few minutes of cooking, add garlic and onions to pan for additional flavor. Continue basting in garlic and onion butter mixture.

Serve and Enjoy!

After steak rests for at least 10 minutes, slice against the grain, and serve immediately. Top with additional compound butter if desired.

Tips for Perfect Sirloin Steak With Garlic Butter

Dry the steak: Pat dry with paper towels – dry surface = better crust.

Salt early (optional but powerful): Salt 30-60 minutes before cooking for deeper seasoning and better texture.

Hot pan, then don’t move it: Let the steak sit to form a crust; flipping too soon prevents browning.

Use oil to sear, butter to finish: Butter burns at high heat- sear with oil first, then add butter later.

Lower heat before garlic: Turn heat down before adding garlic butter so it doesn’t scorch and turn bitter.

Baste quickly: Tilt the pan and spoon garlic butter over the steak for 30-60 seconds for huge flavor.

Rest 5-10 minutes: Juices redistribute-cut too soon and the steak dries out.

Slice against the grain: This is the tenderness cheat code for sirloin.

Finish with flaky salt: Optional, but it makes the flavor pop like a steakhouse.

Garlic Herb Sirloin Steak

By: Courtney ODell
Servings: 4 people
Prep: 15 minutes
Cook: 10 minutes
A seared sirloin steak topped with a dollop of butter and a sprig of thyme, surrounded by chopped onions, garlic, and fresh herbs in a pan.
Juicy, pan-seared sirloin steak finished with rich garlic butter, buttery diced onions, and a melt-over-the-top garlic herb compound butter for steakhouse flavor at home.

Ingredients 

  • 1 ½ –2 lb sirloin steak, top sirloin preferred, 1–1 1/4-inch thick
  • 1 tsp kosher salt, plus more to taste
  • ½ tsp black pepper
  • 1 tbsp olive oil, or avocado oil
  • 1 small yellow onion, diced
  • 3 tbsp butter
  • 4 cloves garlic, minced
  • 1 tsp fresh thyme, or 1/2 tsp dried (optional)
  • 1 tsp fresh rosemary, chopped (or 1/2 tsp dried) (optional)
  • 1 tbsp chopped parsley, optional, for serving
  • Lemon wedges, optional, for serving

Garlic Herb Compound Butter (for serving)

Instructions 

  • Make compound butter: In a small bowl, mash together softened butter, garlic, parsley, thyme, lemon zest, salt, and pepper. Scoop onto parchment/plastic wrap, roll into a log, and chill while you cook (or just keep it in a bowl—either works).
  • Prep the steak: Pat steak dry. Season all over with salt and pepper. (Optional: let sit 30–60 minutes for best crust.)
  • Heat the pan: Heat a heavy skillet (cast iron is ideal) over medium-high to high heat until very hot (sometimes I will pop in the oven for 10-15 minutes to get it scorching). Add oil.
  • Sear: Add steak and don’t move it for 3–5 minutes until browned. Flip and cook another 3–5 minutes.
  • Cook diced onion: Push steak to one side (or remove briefly). Add diced onion to the pan and cook 2–3 minutes until softened and lightly golden.
  • Garlic butter baste: Reduce heat to medium-low. Add 3 tbsp butter, garlic, and thyme/rosemary. Tilt pan and spoon garlic butter over steak for 30–60 seconds. Toss onions in the butter so they get glossy and flavorful.
  • Check doneness: Remove steak at target temp (it will rise while resting):
  • Medium-rare: 125–130°F (rests to ~130–135°F)
  • Medium: 135–140°F (rests to ~140–145°F)
  • Medium-well: 145–150°F (rests to ~150–155°F)
  • Rest: Transfer steak to a board and rest 5–10 minutes. Spoon some pan butter + onions over the top.
  • Serve with compound butter: Slice against the grain. Add a pat of compound butter on each portion and let it melt. Top with more buttery onions, parsley, and a squeeze of lemon if you like.

Notes

Best texture: Sirloin is most tender at medium-rare to medium.
Don’t burn garlic: Always lower heat before adding it.
Onion option: If you want deeper sweetness, cook onions 5–7 minutes (remove steak to rest briefly while onions finish).
Compound butter shortcut: Make a double batch and freeze extra logs for chicken, pork, or veggies.

Garlic Butter Sirloin Steak Recipe Questions Answered

What cut of sirloin is best?

Top sirloin is the best choice for tenderness and flavor. Sirloin tip is leaner and can be tougher, but still works if you don’t overcook it and you slice it thin against the grain.

How do I make steak tender?

Don’t cook past medium (135–145°F final), let it rest, and slice against the grain. Overcooking is the #1 reason sirloin gets tough.

How long should I cook steak in a skillet?

It depends on thickness, but a common range is 3–5 minutes per side over high heat for 1-inch steaks, plus a short rest. Use a thermometer for best results.

When do I add garlic butter?

Add it at the end- once the steak is nearly done and the heat is lowered. Garlic burns fast in a hot pan, so timing matters.

Do I need to marinate sirloin?

Not required with this garlic butter method, but a short dry brine (salt 30–60 minutes) can boost tenderness and flavor.

Can I cook this on the grill instead?

Yes-grill to your target temp, then top with garlic butter while the steak rests so it melts into the meat.

Whats the best temperature for sirloin?

Medium-rare: pull at 125–130°F, rest to ~130–135°F
Medium: pull at 135–140°F, rest to ~140–145°F
Medium-well: pull at 145–150°F, rest to ~150–155°F
(USDA safe temp is 145°F with a rest.)

How do I store and reheat leftovers for sirloin?

Store 3–4 days refrigerated. Reheat gently in a skillet with a splash of broth or a little butter over low heat, just until warm.

Can I make garlic butter ahead of time?

Yes—make and chill up to a week. Slice a pat onto hot steak and let it melt while resting.
