RUMINATIONS
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.
Is Grass Fed Beef More Expensive?
Yes, it is. 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.
Tips on making the medium rare sirloin filets:
- 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

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).
Hi Aye Bea!
I’ll email with my reasons 🙂
Elaine
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
It’s my favorite way to cook it!! Thank you Cynthia!
These look so good! Grass fed beef is the best!
Anne,
Thanks and yes I agree. Grass fed beef is the best!
This recipe looks so good – and who doesn’t love steak? Yum!
Thank you Kristyn!
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.
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!!
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!
Thank you so much Regina! I so appreciate your comment!
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!
Thank you Lindsey. It is super easy!
I can’t believe you made this in the oven! Fabulous – and I haven’t had a steak in a while!
Thanks Lisa! 🙂
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 🙂
Thank you Linda! I hope you try it and enjoy it!
I don’t eat beef but it sure looks like you cooked those steaks perfectly!
Thank you Alyssa 🙂
These sirloin steaks look perfect. Simply perfect.
How long should it cook for a rare steak?
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.
Too cold and wet to grill, so I tried this recipe. Yummy, tender and so easy to do.
Thank you
Thank you Kim!! I appreciate that you took the time to comment. And I’m glad you enjoyed it! Cheers!
