Preparation and cooking overview

Preparing this Filet Mignon requires just 20 minutes. Season the steaks with salt and pepper, and pan-sear them in a hot cast-iron skillet. Next, baste them with an aromatic mixture of butter and herbs, and that’s it! You will get a perfect filet mignon without any hassle!

Chef’s note

Enhance the flavors by adding a tablespoon of keto-friendly red wine during searing. Wine will tenderize the meat and add a delightful sweetness. Alternatively, you can create a delicious steak sauce. After removing the steaks, add wine or balsamic vinegar to the pan, scrape any browned bits, and simmer to reduce the sauce. Finish by stirring in a dollop of butter and drizzling the sauce over the steaks before serving.

Chef’s pro tip

Here’s a helpful tip for the perfectly cooked filet mignon. Take the steaks out of the fridge approximately 30 minutes before cooking. Allow them to come to room temperature. After searing, let the steaks rest for 5 minutes. The resting time redistributes the flavorful juices, resulting in a juicier steak.

What to serve with filet mignon?

Pair these juicy steaks with other keto-friendly options for a complete meal:

Creamy cauliflower mash: Serve the filet mignon over a bed of creamy Cauliflower Mash for a low-carb side.
Garlicky green beans: Our Garlic Butter Green Beans are a great pairing option with this delicious dish.
Grilled asparagus: The smoky taste of grilled asparagus pairs perfectly with the meat’s richness. You can also try our Mediterranean Asparagus for an additional flavor boost.
Grilled vegetables: Nothing can beat the amazing flavors of Grilled Vegetables! They add a nice crunch and loads of fiber to a meaty dish. You can also try Fried Eggplant With Tomato Sauce as a perfect addition to the steak.
Greek salad: A crisp, refreshing Greek Salad provides a light and tangy contrast to the hearty dish.

How to choose the best filet mignon?

When buying the cut, consider these factors to get the best steak.

Quality: Opt for filet mignon from high-quality sources, such as prime-grade beef. High-quality beef ensures superior tenderness, marbling, and flavor.
Size and thickness: Filet mignon steaks are typically cut into individual portions, ranging in thickness from around 1.5 to 2 inches.
Marbling: Look for filet mignon with moderate marbling, which refers to the thin streaks of fat running through the meat.
Butcher’s assistance: Don’t hesitate to ask your butcher for help. They can guide you in selecting the filet of the highest quality cuts.

How to make it healthier?

Reduce salt: Use less salt in the seasoning. Trust us, your steak will still be packing a punch.
Make it dairy-free: Swap butter with coconut or extra virgin olive oil if you want a dairy-free version. These alternatives keep your recipe dairy-free and add a layer of subtle, unique flavors.

What can I prepare ahead of time?

Season the steaks: Season the filet steaks with salt, pepper, fresh lemon juice, and olive oil up to 24 hours in advance. This will save you time on the cooking day and allow the salt to penetrate deeper into the meat, enhancing the flavor.

Storage and reheating instructions
