Pan Seared Filet Mignon with Rosemary & Garlic: An easy recipe that is out of this world tender, juicy, & so flavorful! The rosemary & garlic are a perfect match for this high quality cut of meat (also known as a tenderloin).
We made Pan Seared Filet Mignon with Rosemary & Garlic for my husband’s birthday this year and it was beyond amazing. Not only was dinner on the table in less than 30 minutes, but we felt like we were eating at a five-star restaurant.
It took a couple tries (and all the tenderloins in the freezer) to get this recipe just right. For us, more garlic is better and eating whole cloves with succulent bites of steak is our favorite. So … generous garlic … like two bulbs!
This meal is definitely a special occasion for us; however, we only paid $4.40/pound for these tenderloins. I have blogged all about how to do this in How To Buy Grass-fed Beef.
If you have fresh rosemary on hand, that is best. I did use dried rosemary the second time because I forgot to get fresh rosemary (and there’s no going back to the store at 5:45 pm with two little kids & a husband who is coming home hungry!).
We like to use grass-fed butter with Pan Seared Filet Mignon, but high-heat oils such as refined coconut oil, avocado oil, or beef tallow all work as dairy-free options.
Honestly, it’s probably considered cheating to post this recipe as my own because I gave the ingredients to my husband, handed him the salted, room temperature tenderloins, and he worked the magic from there. He used a cast iron pan on a charcoal grill to sear the filets. Don’t worry, I got all the details of exactly how he prepares it, so you can replicate it perfectly.
I chose to use rosemary in this recipe because it helps to block carcinogens,¹ and served the Pan Seared Filet Mignon with cruciferous vegetables because of emerging research² showing them to be anti-carcinogenic.³
Pan Seared Filet Mignon goes great with:
- Black Bean Brownies or Cheese-less Cheesecake for dessert
- Roasted & Salted Butternut Squash for a healthy carbohydrate
