How to Cook Baked Sirloin Steak (in 22 min)

Tender and juicy Mustard Herb Baked Sirloin Steak recipe starts with a quick sear in a cast-iron pan and finishes off in the oven. This recipe is so quick and easy, you can have steak dinner night of the week.

I have always been a fan of searing steaks on the stove in a cast-iron skillet and then finishing them in the oven. They turn out perfectly cooked every time and you can season them so many different ways.

For this sirloin steak recipe, Italian herbs and mustard coat the steaks. As the steak hits the hot skillet, the mustard begins to brown and caramelize, creating a beautiful crust.

It’s truly the perfect meal because who doesn’t love steak?! It’s one of those meals the entire family can agree on. Pair it with this Roasted Brussels Sprouts with Balsamic Glaze recipe for an impressive side dish.

This baked sirloin is tender and juicy and is the best way to get a hearty dinner on the table in a hurry. We also love Sheet Pan Steak Fajitas and this Pan Seared Steak Chimichurri. Both are super easy and loaded with incredible flavor.

This perfectly oven cooked sirloin steak recipe is fool-proof way to cook a reasonably priced steak without sacrificing taste and tenderness. Baked sirloin steak is a great way to serve steak when it’s too cold or rainy to grill outdoors.

Can you bake sirloin steak without drying it out?

Absolutely! With a quick sear on stove top, a sirloin steak will come out of the oven juicy and cooked perfect when using an Instant Read Thermometer.

Why We Love This Recipe

• Flavor: Searing them first, slightly caramelizes the mustard herbed rub on the steaks, giving them incredible flavor.
• Ease: Cooking steaks in the oven means you can have the best steaks anytime you want them without having to break out the grill.
• Great for meal prep: Because these steaks take less than 30 minutes to prepare to medium doneness, they are an easy way to meal prep for the week. You can have leftovers in a salad one night, in a wrap for lunch or even reheat the steak and serve with eggs for breakfast.

Steak Doneness Temperature Ranges:

When determining the temp of a steak, check the thickest part of the meat with a digital meat thermometer. Use this guide to help determine when your steak (based on a 1.5 inch steak) has reached the desired doneness:

• Rare – 120F 2 min Rare steak will have a cool-to-warm very red center with very soft texture.
• Medium Rare -130F 3 min Medium rare steak will have warm but very red center with a nice brown crust.
• Medium – 140F 4 min Medium steak will have a hot pink center and slightly firmer texture.
• Medium Well -150F 5 min Medium steak will have mostly a brown center with maybe the slightest hint of pink with firm texture.
• Well Done – 160+F 6 min Well-done steak will have no sign of pink at all and will be very firm and much drier.

Tips for Cooking Sirloin Steak

• One of the biggest myths in cooking steak is that you should never start out with cold meat. We have been told for years to set steaks out for a least an hour before cooking. That is simply not true. If you’re wanting a steak that is nice and seared on the outside, but pink and juicy on the inside, you should cook your steak straight out of the fridge.

• Allow for residual cooking. When cooking steak, whether it is one the grill, in the oven or stove top, you want to remove it from the heat when it is about 5 degrees less than the desired temp on an instant-read thermometer. The temperature will continue to rise while the meat rests.

• Always allow steaks to rest: Steaks, just like most any meat needs to rest for about 10 minutes after it has finished cooking. This allows all those yummy juices to redistribute through the steak.
• For really juicy steaks, you want to look for ones that have a good bit of marbling that is well distributed through the steak.
