Steak is one of my family’s favorite foods. But for so long, I never thought I could make a steak at home that would be as good as what you get in a restaurant.
This grilled filet mignon instantly proves that theory wrong! It’s perfectly seasoned with a melt-in-your-mouth tenderness that makes it irresistible.
Filet mignon is known for being the most tender cut of steak. Because it’s a leaner cut of beef, it’s best served medium or medium-rare to keep it from drying out and losing that wonderful texture.
So today, I’ll be showing you how to grill filet mignon to perfection! Whether you use an outdoor gas grill or Ninja Foodi Indoor Grill, I know you’re going to love this simple but indulgent steak recipe.
Ingredients for Cooking Filet Mignon
- Steak - You want 1½ pounds of prime, choice, or select filet mignon. Aim for something that is around 1 ½ to 2 inches thick.
- Oil - I recommend using avocado oil because of its high smoke point. I do not recommend using extra virgin olive oil at high heat.
- Seasoning - Dried rosemary, salt, and pepper really enhance the natural flavors of the filet mignon. I recommend either kosher salt or sea salt.
- Compound butter - Learn to easily make your own here!
Tips & Tricks
- Before grilling filet mignon, let the steaks rest at room temperature for 1 hour. This makes it easier to evenly cook this filet mignon recipe.
- Use a filet mignon grill time chart and instant-read thermometer to find the best cooking time. The instructions in this recipe are a good basis, but cooking time will always vary slightly based on the size and thickness of your steak.
- Always let the steak rest before slicing into it. If you cut into it too soon, you’ll lose some of the juice that keeps the meat tender.
Serving Suggestions
- When you’re craving the steakhouse experience, serve a flavor-packed Keto Caesar Salad alongside your main dish.

These times work well for me, but I always recommend meat thermometers to ensure the perfect heat. Cooking times will vary slightly based on the size and thickness of your steak.
