This filet mignon with blue cheese butter makes the perfect low carb Valentine’s day dinner. The decadent butter and the tender beef are also very easy to prepare for a special occasion.
I like steak but I really, really like filet mignon. Of course I rarely buy it because it is expensive but hey, it’s Valentine’s day. Nothing makes it easier to have a low carb Valentine’s Day than to serve steaks and in this case filet. And to top it off, add some rich and decadent blue cheese butter. Seriously this could be one of my top 5 dinners of all time and best of all it takes very little time.
You want to start off with a nice piece of filet. These are 10 – 12 oz each and a good 2 inches thick which is perfect if you want a nice rare piece of steak. If you want to save a little money, you could cut these in half and have thinner steaks and they would be just as delicious. You just wouldn’t cook them as long. Also use a good cast iron skillet to sear the steaks and then finish them off in the oven. I have this one and I love it.
How to cook the perfect filet mignon
- First let the meat set out for 30 minutes.
- Next get your cast iron skillet nice and hot.
- Add butter and oil to the skillet.
- Sprinkle salt and pepper over the filets.
- Sear the steaks on both sides, approximately 3-5 minutes depending on thickness.
- Place in a 425 degree F oven for 5 minutes.
- Take out and let set for about 5 -10 minutes.
A pat of flavored butter is a great low carb way to make any protein or vegetable delicious. I have a yummy salmon with lemon herb butter recipe that you may like too. Mix your butter with any combination of herbs and spices and then freeze for later use. Just place on a steaming plate of asparagus or broccoli to add lots of flavor.
Blue Cheese Butter Recipe
- Mix 3 tablespoons of crumbled blue cheese with 4 oz of good butter.
- Spoon and press into a mold or ice cube tray.
- Freeze and then store in freezer.
- Let thaw before using.
- Place on steaks, fish, chicken or vegetables.
I served these with mushrooms. Simple saute baby portobello mushrooms in butter and season with salt and pepper. Let them get nice and brown for maximum flavor. I have rich cauliflower mash coming up that would be nice with this meal too. I hope you enjoy this low carb Valentine’s Day dinner. This is one of those days that eating low carb is easy. The nutrition for 1/2 steak (these really were big) and 1 pat of butter is:
1 butter pat = 79 cals / 8.4g fat / 0.1g carbs / 0.8g protein = 0.1g net carbs
1/2 steak (~5 oz) = 405 cals / 31.3g fat / 27.5g protein = 0 net carbs
