This medium rare sirloin recipe comes out perfect every single time. Marinate the sirloin, bake it in the oven and when you cut into it, you’ll marvel at how easy and delicious it is.
It is so funny to me that I’m making sirloin steak filets on a regular basis.
Why, you ask?
Because we were vegetarians for a good chunk of time. And once we started eating meat again, it took me years to be comfortable making steak.
If I’d have known how easy it was, I would have started making it a lot sooner.
Does grass fed beef taste different?
You bet your sweet bippy it does. At least it does to me and I believe it would to you too. If I made this exact dish with one grass fed steak and one regular steak and you tried them side by side, you would see what I mean.
Here’s a great chart that shows you all the different cuts of beef and how to cook them.
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.

Helpful Tips
- Use a gallon zip lock bag to marinate the filets, it’s cheap and easy
- Place sirloin into the bag and add all the marinade ingredients. Knead the bag to mix and cover the sirloin with the marinade
- Place the bag of steak on the counter for an hour before you bake it so the sirloin gets to room temperature
- Cover a jelly roll pan with foil and place a wire rack on the pan for easy clean up
- Bake first at a low temperature and when you raise the temperature of the oven, make sure to take the filets out of the oven until it comes to temperature
Process shots
- Grass-fed sirloin, dried basil, garlic powder, salt, pepper and Worchestershire sauce
- Pan with marinated sirloin ready to be put in the oven
- Sirloin out of the oven, resting for 5 minutes before cutting into it
Steps
- Heat oven to 285 degrees Fahrenheit
- Bake for 20 minutes. Take out sirloin and raise temperature to 425 F
- Bake for 10 minutes
- Let rest for 5 minutes before serving and cutting into the steak
Do I use a thermometer to check the doneness? No, I have been doing this a while now and I know how to get medium rare sirloin. But if you have a thermometer, by all means use it if it gives you more peace of mind.
Let’s plate the medium rare sirloin filets, shall we? I arrange them on the plate with my Colorful Roasted Baby Potatoes and a modest handful of asparagus spears.
Time to cut into the medium rare sirloin steak. I can’t wait!
Knife time
Jump into my mouth, piece of filet! Right now!
Christopher held the fork for me while I took the shot.
I snapped away, reached over, grabbed that piece off the fork and popped it into my mouth.
Mmmmm. Tender and delicious!
I hope you enjoyed this medium rare sirloin recipe!

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).
Elaine
Hi Aye Bea!
I’ll email with my reasons đŸ™‚

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
Elaine
It’s my favorite way to cook it!! Thank you Cynthia!
Anne Lawton

Kristyn
This recipe looks so good – and who doesn’t love steak? Yum!
Elaine
Thank you Kristyn!
Grass-fed Beef
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.
Elaine
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!!
Regina
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!
Elaine
Thank you so much Regina! I so appreciate your comment!

Elaine

Elaine
Thank you Linda! I hope you try it and enjoy it!
Alyssa
I don’t eat beef but it sure looks like you cooked those steaks perfectly!
Elaine
Thank you Alyssa đŸ™‚
Christopher
These sirloin steaks look perfect. Simply perfect.
Elizabeth
How long should it cook for a rare steak?
Elaine
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.
Kim
Too cold and wet to grill, so I tried this recipe. Yummy, tender and so easy to do.
Thank you
Elaine
Thank you Kim!! I appreciate that you took the time to comment. And I’m glad you enjoyed it! Cheers!
