Filet Mignon is a tender and juicy cut of beef that melts in your mouth. It’s often seen as a fancy dish because of its rich flavor and buttery texture.
Cooking it just right can make you feel like a chef! I like to pair it with some roasted vegetables for a simple but elegant meal. You won’t believe how good it tastes!
Key Ingredients & Substitutions
Filet Mignon: The star of the show! Look for steaks that are at least 1.5 inches thick for the best texture. If filet mignon is too pricey, you could use sirloin or ribeye, but the texture will differ.
Olive Oil: I prefer olive oil for its flavor, but vegetable oil or canola oil works too. If you’re looking for a richer taste, consider grapeseed or avocado oil as alternatives.
Unsalted Butter: Using unsalted butter lets you control the saltiness. If you’re dairy-free, replace it with a plant-based butter or an extra splash of oil.
Garlic: Fresh garlic is best, but garlic powder can work in a pinch. I love the flavor garlic adds to the pan, making everything more aromatic.
Mushrooms: Cremini are my favorite for their deep flavor, but button mushrooms are perfectly fine. You could also use shiitake or portobello if you want a different taste.
Asparagus: If asparagus isn’t in season, green beans or broccolini can be great substitutes, keeping the vibrant feel of the dish.
How Can I Sear the Perfect Steak?
Searing is vital for developing that delicious crust on filet mignon. Start with a hot pan to lock in juices and flavor. Here’s how to nail it:
- Make sure the steak is at room temperature before searing. This helps it cook evenly.
- Use a heavy skillet or cast iron pan to hold heat better.
- Do not overcrowd the pan; cook one or two steaks at a time if needed.
- Sear for 3-4 minutes on one side without moving it, then flip it and add butter and aromatics.
- For perfect doneness, use a meat thermometer. Aim for 130°F for medium-rare.
Resting the steak after cooking helps keep it juicy, so don’t skip that step!

How to Make Filet Mignon with Mushrooms and Asparagus
Ingredients You’ll Need:
For the Steak:
- 2 filet mignon steaks (about 6 oz each, 1.5 to 2 inches thick)
- Salt and freshly ground black pepper, to taste
- 2 tbsp olive oil or vegetable oil
- 2 tbsp unsalted butter
- 2 cloves garlic, crushed
- 2 sprigs fresh rosemary
For the Veggies:
- 1/2 cup sliced mushrooms (such as cremini or button)
- 6-8 asparagus spears, trimmed
- Fresh parsley or additional chopped rosemary for garnish (optional)
How Much Time Will You Need?
This recipe takes about 15 minutes for preparation and cooking. You’ll want to allow an extra 5 minutes for resting the steaks later. So, in total, plan for around 20 minutes for this delicious and elegant meal!
Step-by-Step Instructions:
1. Prepare the Steaks:
First, take the filet mignon out of the refrigerator and let them rest at room temperature for about 30 minutes. This helps them cook evenly. Pat the steaks dry with paper towels and then season both sides generously with salt and freshly ground black pepper.
2. Sear the Steaks:
Heat the olive oil in a heavy skillet or cast iron pan over medium-high heat until it shimmers. Carefully add the filet mignon steaks to the hot pan. Sear them without moving for about 3-4 minutes until you see a rich brown crust form on the bottom.
3. Add Flavor:
Flip the steaks over and add the unsalted butter, crushed garlic cloves, and rosemary to the pan. As the butter melts, tilt the pan slightly and use a spoon to baste the melted butter and garlic over the steaks for another 3-4 minutes. For medium-rare, look for an internal temperature of about 130°F.
4. Let Them Rest:
Once they’ve reached your desired doneness, take the steaks out of the pan, tent them loosely with foil, and let them rest for 5 minutes. This allows the juices to redistribute.
5. Cook the Veggies:
In the same pan, add the sliced mushrooms. Sauté them for about 3 minutes in the leftover steak drippings until they become browned. Then, toss in the asparagus spears and cook for an additional 2-3 minutes until they are tender-crisp.
6. Time to Serve:
Plate the filet mignon and top them with the sautéed mushrooms and asparagus. If you like, sprinkle some fresh parsley or chopped rosemary on top for a lovely garnish. Enjoy your delicious meal!
This classic preparation highlights the tender, buttery texture of the filet mignon with aromatic rosemary and savory mushrooms, perfectly complemented by vibrant asparagus. Enjoy!
Can I Use a Different Cut of Meat?
Absolutely! If filet mignon is not available or too expensive, you can use ribeye or sirloin. Just keep in mind that cooking times may vary based on the thickness and fat content of the cut you choose.
How do I Know When the Steak is Done?
The best way to check doneness is to use a meat thermometer. For medium-rare, aim for an internal temperature of 130°F. If you prefer it more cooked, aim for 140°F for medium and about 160°F for well-done.
Can I Prepare This Dish in Advance?
While the steak is best enjoyed fresh, you can prep the mushrooms and asparagus ahead of time. Just sauté them when you’re ready to serve. You can also season the steak in advance but cook it as close to serving time as possible for the best texture.
How Should I Store Leftovers?
Store any leftover steak and vegetables in an airtight container in the fridge for up to 3 days. To reheat, place in a skillet over low heat or in the microwave on a lower power setting, being careful not to overcook it.
