The Steps of Preparation (Possible in All Kinds of Variations)

The key to a perfect filet mignon on the Blackstone griddle is achieving a golden crust while keeping the inside tender and juicy. Follow these steps for absolute perfection:

1. Preheat your Blackstone griddle to medium-high heat (around 450-500°F). Let it heat for at least 5-10 minutes to ensure a good sear.
2. Pat the steaks dry with a paper towel to remove excess moisture. This helps with the crust formation.
3. Season generously on both sides with salt and pepper. Let the steaks sit at room temperature for about 30 minutes before cooking.
4. Add a thin layer of oil to the griddle and spread it evenly.
5. Place the filet mignon on the hot griddle and sear for 3-4 minutes per side without moving them. This helps develop a golden-brown crust.
6. Flip the steaks and let them cook for another 3-4 minutes on the other side.
7. Add butter, garlic, and fresh herbs to the griddle, allowing them to melt and create an aromatic baste.
8. Baste the steaks by tilting the griddle slightly and spooning the butter over the filet for extra juiciness.
9. Check for doneness using a meat thermometer:
   • Rare: 120-125°F
   • Medium-Rare: 130-135°F
   • Medium: 140-145°F
   • Medium-Well: 150-155°F
   • Well-Done: 160°F+
10. Remove the steaks from the griddle and let them rest on a plate for 5-10 minutes to allow juices to redistribute.
11. Slice and serve with your favorite sides, like mashed potatoes, grilled asparagus, or a fresh salad.

Frequently Asked Questions

How long should I cook filet mignon on a Blackstone griddle?
It depends on the thickness and desired doneness. A 1.5-inch steak will take about 8-12 minutes total for medium-rare.

Can I use frozen filet mignon?
For the best results, always cook thawed filet mignon. Cooking from frozen will result in uneven doneness.

What oil should I use for cooking?
Use high-smoke-point oils like avocado, grapeseed, or canola oil. Avoid olive oil, as it burns at high heat.

Should I marinate filet mignon before cooking?
Filet mignon is naturally tender, so a simple seasoning of salt and pepper is enough. However, you can marinate if you prefer added flavor.

How do I know when the steak is done?
Use a meat thermometer to check internal temperature: 130°F for medium-rare, 140°F for medium, etc.

Can I cook filet mignon without butter?
Yes, but butter adds incredible richness and flavor. If you’re avoiding dairy, use ghee or a high-quality oil.

What sides go best with filet mignon?
Some great options are garlic mashed potatoes, roasted Brussels sprouts, grilled asparagus, or a simple arugula salad.

Can I cook filet mignon on a Blackstone griddle without a thermometer?
Yes! Use the finger test: Press the steak—soft is rare, firm is well-done.

Why is my steak tough?
Overcooking or skipping the resting period can lead to toughness. Always let the steak rest for at least 5 minutes before slicing.

How do I get the best crust on my filet?
Make sure your steak is dry before cooking, and don’t move it while searing. A hot griddle and proper seasoning also help.
