Medium Rare Sirloin Filets

These medium rare sirloin filets are juicy, tender, and dripping with flavor. Marinated in Worcestershire sauce and a delicious blend of spices, then oven-roasted to perfection, this sirloin steak recipe promises to be the star of the show.

I started cooking steak in the oven because we didn’t have a gas grill. I love steak and wanted to eat it without cooking it on the stove top. So I came up with this easy and no-fail way of having perfectly cooked steak.

Do I miss the sear on the steak? Absolutely not, because the flavor of this steak is outstanding and it comes out medium rare every single time.

Does grass fed beef taste different?

Yes. If I made this exact dish with one grass fed steak and one regular steak and you tried them side by side, I believe you would taste the difference.

It is more expensive than conventional beef but it is so worth the extra expense. The cow is allowed to graze, is not given hormones and is raised more ‘naturally’ then non grass fed cows. You can taste the difference in the meat.

Here’s a great website that shows you all the different cuts of beef and how to cook them.

Helpful Tips

• Although I usually shy away from using plastic bags, I use a gallon zip lock bag to marinate these filets. This allows me to massage the sirloin, and it’s easy to flip around the steak so the marinade coats it efficiently.
• I usually add basil to the marinade, but oregano is also a great option.
• Place the sirloin into the bag, add all the marinade ingredients, and knead the steak through the bag.
• Cover a jelly roll pan with foil and place a wire rack on the pan for easy clean up.
• You will be baking the steak first at a low temperature. Then you need to remove the filets and raise the oven’s temperature, so you finish cooking the meat at a high heat.
• Once you raise the oven’s temperature, you have to wait for the oven to come to temperature before you put the steaks back in the oven.

How to make medium rare sirloin steak

Pre-step

Cover a jelly roll pan with foil and place a wire rack over it.

Step one

Gather the ingredients – grass-fed top sirloin steak, dried basil, garlic powder, salt, pepper, and Worcestershire sauce.

Step two

In a small mixing bowl, add the marinade ingredients (A), and whisk until combined. (B)

Step three

Take the steak out of the packaging and blot dry with a paper towel. (C)

Place the steaks in a gallon sized ziplock bag and add the marinade. Knead the steak through the bag and place on the counter for an hour. (D)

Knead the steak again after a half hour has gone by.

Step four

Before the hour is up, preheat oven to 285 degrees Fahrenheit.

Step five

Take the marinated steak out of the bag and place on the wire rack on the jelly roll pan. (E)

Step six

Place in the oven and bake for 20 minutes.

Step seven

Take the steak out of the oven and raise the temperature to 425 degrees F.

Step eight

Once the oven has come to temperature, place the sirloin steak back in and bake for 10 minutes. (F)

Step nine

Let the steak rest for 5 minutes before serving and cutting into it.

Do I use an instant-read thermometer to check the doneness? No, I have been doing this a while now and I know how to get my steak medium rare. But if you have a meat thermometer, by all means use it if it gives you more peace of mind. Your steak temperature should be between 130 – 135 degrees Fahrenheit.

Time to plate the steak with my roasted potatoes and some sautéed cabbage.

So juicy.

Time to cut into the medium rare steak. I can’t wait!

Mmmmm. Tender and delicious!

I hope you enjoyed this medium rare sirloin recipe!
