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.

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.

  1. Awesome! I’ve not seen steak cooked fully in the oven since…well what, the 90’s? So easy, so delicious!

    Would love to hear more about your journey back to eating meat/reasons why! Having a hell of a time justifying my transition back to others (even though I KNOW my health will improve from it tremendously).

  2. Now this looks like a steak I could really sink my teeth in. I have watched show where they cook a steak in the oven for a while, but have never tried. it. If mine look like this – I will be happy

  3. Thanks Elaine, this looks like a great recipe for grass-fed steaks. Putting it back in the oven to make sure it is medium rare is key. Look forward to your other recipes.

    1. I agree! And thank you! I’ll be checking out your site as well. Got to love grass fed beef. There is nothing like it!!

  4. If it weren’t for my husband, I probably could be vegetarian too. I am the same as you, chicken, shrimp no problem, but I have some trepidation when it comes to red meat, especially steak. I just don’t know how to cook it but your instructions sound super easy!

  5. It’s so rare that I cook, but I bake all the time! So I looove that I can make a perfect steak in an oven. Thanks for sharing!

  6. I can’t believe you made this in the oven! Fabulous – and I haven’t had a steak in a while!

  7. I never cooked a steak in the oven, I am so curious to try it! And thanks for the detailed instructions, you make it look doable and easy 🙂

    1. Hi Elizabeth! I would say follow the directions for the first part – 285F for 20 minutes and then pull it out and set the oven to 425 and once it comes to temperature, cook for 6-7 minutes instead of 10 – let rest for 5 minutes and then it will be rare. Hope this helps.
