What Ingredients You Will Need

This recipe keeps things straightforward with a focus on quality and freshness. Each ingredient plays its part, from the tender filet to the creamy blue cheese butter that finishes the dish with flair. Here’s what you’ll need:

• For the Filet Mignon:
  • 2 filet mignon steaks (6-8 oz / 170-225 g each), about 1.5-2 inches thick
  • Salt and freshly ground black pepper, to taste
  • 2 sprigs fresh thyme or rosemary (optional for aroma)
  • 1 tablespoon olive oil for searing
• For the Blue Cheese Compound Butter:
  • 4 tablespoons unsalted butter, softened (I prefer Kerrygold for richness)
  • 2 ounces blue cheese, crumbled (Roquefort or Gorgonzola work great)
  • 1 small garlic clove, minced
  • 1 teaspoon fresh lemon juice (adds brightness)
  • 1 tablespoon finely chopped fresh parsley (optional, for color and freshness)
  • Pinch of black pepper

If you want to swap the blue cheese for a milder flavor, try a creamy goat cheese or even a sharp cheddar. For a dairy-free twist, use a plant-based butter and omit the cheese entirely—though honestly, the blue cheese is what makes this taste sing!

Equipment Needed

• Sous vide immersion circulator and a large pot or container for water bath (if you don’t have a sous vide, a precision cooker like the Anova or Joule works brilliantly)
• Vacuum sealer and bags, or high-quality resealable freezer bags (I sometimes use the water displacement method with zip-lock bags when in a pinch)
• Cast iron skillet or heavy-bottomed pan for searing (I love my Lodge cast iron for this step)
• Tongs for flipping the steaks
• Mixing bowl and spoon for preparing compound butter

If you’re on a budget, you can find affordable sous vide sticks that plug into any pot. For sealing, if you don’t own a vacuum sealer, carefully immersing the bag in water to push air out is a handy alternative. The searing pan should be heavy enough to hold heat well; this small investment makes a huge difference in the crust development.

Preparation Method

1. Season the Steaks: Pat the filet mignon dry with paper towels. Generously season both sides with salt and black pepper. Add the thyme or rosemary sprigs if using. This step is crucial for flavor and crust formation after sous vide cooking. (~5 minutes)
2. Bag the Steaks: Place each steak into a vacuum bag with the herbs. Seal using a vacuum sealer or use the water displacement method with zip-lock bags: slowly lower the bag into water, letting pressure push out air, then seal tightly. (~5 minutes)
3. Set Up Sous Vide: Preheat your water bath to 129°F (54°C) for medium-rare. Adjust temperature slightly if you prefer it more rare or medium. (~10 minutes to preheat)
4. Cook the Steaks: Submerge the sealed bags fully in the water bath. Clip bags to the side to avoid floating. Cook for 1 to 1.5 hours—no worries if you go a bit longer; sous vide is forgiving. (~1.5 hours)
5. Make the Blue Cheese Compound Butter: While the steaks cook, combine softened butter, crumbled blue cheese, minced garlic, lemon juice, parsley, and a pinch of black pepper in a bowl. Mix thoroughly until smooth. Transfer to plastic wrap, roll into a log, and chill in the fridge until firm. (~10-15 minutes)
6. Remove and Dry Steaks: Once cooked, remove the bags from the water bath. Take steaks out and pat dry very well with paper towels—dryness is key for a good sear. (~5 minutes)
7. Sear the Steaks: Heat olive oil in a cast iron skillet over high heat until just smoking. Add steaks and sear for about 45 seconds to 1 minute on each side, including edges, until a rich brown crust forms. Use tongs to carefully hold steaks on edges. (~5 minutes)
8. Rest and Serve: Transfer the steaks to plates, slice a generous round of the blue cheese compound butter, and place on top while steaks are hot. Let it melt slowly, and serve immediately. (~5 minutes)

Tip: If you get interrupted mid-sear (true story), just keep the pan hot and return quickly! The crust is worth the extra attention. The smell of the seared steak alone is enough to pull anyone into the kitchen.

Cooking Tips & Techniques

Cooking filet mignon sous vide is forgiving, but some things really help nail it every time. For example, drying the steak thoroughly before searing is a must—moisture equals steam, and nobody wants that instead of a crust.

Also, gently pressing the steaks into the pan rather than moving them around too much helps build an even crust. Honestly, I’ve learned the hard way that flipping repeatedly just messes with the sear.

Using a heavy pan like cast iron ensures the heat stays steady, so your steak gets that beautiful Maillard reaction without burning. If your pan isn’t hot enough, you’ll miss that signature crust and end up with a dull exterior.

Multitasking during sous vide cooking is a lifesaver. While the steaks cook, make your compound butter and prep sides. It keeps the kitchen flowing and you won’t feel rushed during that crucial searing stage.

Finally, don’t skip the rest after searing. Letting the steak sit a few minutes with the butter on top lets flavors meld and juices redistribute, making each bite tender and flavorful.

Variations & Adaptations

• Herb-Infused Butter: Swap parsley for chives, tarragon, or basil to customize your compound butter’s herbal profile.
• Spicy Kick: Add a pinch of cayenne or smoked paprika to the butter for a subtle heat that pairs wonderfully with the richness of the steak.
• Allergy-Friendly: For dairy-free, use vegan butter and omit blue cheese. A sprinkle of nutritional yeast can add a cheesy flavor punch.
• Alternative Cooking: If you don’t have sous vide gear, try the reverse sear method: slow roast filet at 275°F (135°C) until internal temp hits 125°F (52°C), then sear in a hot pan.
• Personal Twist: I once tried swapping blue cheese for a truffle butter, which was decadent but a bit overpowering—blue cheese keeps the balance just right.

Serving & Storage Suggestions

Serve your perfect sous vide filet mignon immediately after searing with the melting blue cheese butter on top. A simple garnish of fresh herbs adds a pop of color. This pairs beautifully with roasted garlic mashed potatoes, sautéed green beans, or a crisp arugula salad.

For beverages, a full-bodied red wine like Cabernet Sauvignon or Malbec complements the steak’s richness. If you prefer beer, try a malty brown ale.

Leftovers can be wrapped tightly and stored in the refrigerator for up to 2 days. To reheat, gently warm in a low oven (about 275°F/135°C) until just warmed through, then refresh the crust with a quick sear. Avoid microwaving—it toughens the meat.

Flavors meld overnight, so if you prepare the butter ahead, it becomes even more aromatic by serving time.
