What You Need To Make This Pan Seared Filet Mignon With Creamy Mushroom Sauce:
For the pan seared filet mignon:
- (2) 6-8 ounces filet mignon steaks- I like using Butcher Box. They ship you a monthly supply of grass fed meats every month. I find their quality is the absolute best. I can taste a difference in the steak too. If you use my link HERE, you can get $30 off your first order.
- Pink sea salt & pepper- This is what is used to seasoned the steaks. If you are doing AIP, be sure to omit the black pepper.
- Ghee- I like using ghee in place of butter to give my dishes the buttery flavor.
For the Creamy Mushroom Sauce:
- Mushrooms-This are a necessity! This is what makes the mushroom sauce 🙂
- Ghee-Again, this is what makes the buttery taste in the sauce. If you can tolerate dairy, you could use regular butter.
- Purple onion & garlic- Adds so much flavor! In my opinion, the more garlic the better.
- Lemon juice-This is a must. This will add a kick to the sauce. Without this, the sauce is bland.
- Bone broth & almond milk-This is what gives that sauce that creamy flavor. If you are doing AIP, you can use full fat coconut milk.
- Water & arrowroot- Arrowroot is similar to cornstarch in paleo cooking. It is a staple in my house. We use it to thicken up our sauces.

For The Sauce:
