Understanding the Standard Filet Mignon Weight
While there is no single, mandatory size, the term "standard" often applies to an 8-ounce (about 225g) filet mignon in the United States. This cut is typically between 1.5 and 2 inches thick, which is ideal for getting a good sear on the outside while leaving the interior perfectly pink and tender. However, you will find a wide variety of portion sizes available, from smaller cuts known as "petit filet" to much larger, extravagant versions served in high-end steakhouses.
Factors That Influence Filet Mignon Size
The weight of a filet mignon is not arbitrary. It's determined by several factors, including the source of the cut, regional preferences, and market demand.
- Butcher's Cut: A butcher or meat purveyor will slice the filet mignon from the beef tenderloin. They have the discretion to cut steaks into varying thicknesses and weights to cater to different customer needs, from a modest dinner portion to a more substantial entrée.
- Regional Differences: In Europe, for example, a filet mignon might be a smaller, thinner cut weighing around 3-4 ounces, while in the US, portions are generally larger. This difference reflects varying culinary traditions and serving styles.
- Type of Establishment: A fine-dining steakhouse might offer a range of sizes to accommodate different appetites, such as a petite 6 oz option and a hearty 12 oz cut. Grocery stores often stock a more limited, standard selection, usually within the 6 to 8-ounce range.
- Personal Preference: Ultimately, the size you choose depends on your own appetite and how you plan to prepare the meal. A smaller filet might be perfect for a lighter dinner, while a larger one could be the centerpiece of a special occasion.
How Filet Mignon Size Impacts Cooking
Cook time is heavily influenced by the steak's weight and thickness. A thicker, heavier filet will require more time to cook through to your desired doneness, while a thinner cut will cook much more quickly.
- Thinner cuts (e.g., 4-6 oz): These petite filets require careful attention to avoid overcooking. A quick sear and a short rest might be all that's needed for a perfect medium-rare finish.
- Standard cuts (e.g., 8 oz): This is the sweet spot for many home cooks. The thickness allows for a good, even sear and more control over the cooking process, whether you're using a pan-sear to oven-finish method or grilling.
- Thicker cuts (e.g., 10-12+ oz): For these larger steaks, methods like the reverse sear, where the steak is cooked at a low temperature before a high-heat sear, are often recommended. This ensures the center cooks evenly without burning the exterior.
Filet Mignon Size Comparison
| Weight (Ounces) | Typical Use Case | Approximate Thickness (Inches) | Best for... |
|---|---|---|---|
| 4 oz | Petite serving, lighter meal | 1 - 1.5 | Quick searing and single servings |
| 6 oz | Standard personal portion | 1.5 - 2 | Average appetite, classic restaurant size |
| 8 oz | Large personal portion, fine dining standard | 1.75 - 2 | Heartier meals, achieving a perfect medium-rare |
| 10 oz | Large steakhouse serving | 2.25 - 2.5 | Larger appetites, special occasions |
| 12+ oz | Extra-large steakhouse cut | 2.5 - 3+ | Heartiest appetites, best for low and slow methods |
Cooking Methods by Filet Size
The most suitable cooking method for a filet mignon often depends on its size. This ensures the tenderness and mild flavor are maximized.
Sous Vide
For thicker cuts, the sous vide method is highly effective. It involves vacuum-sealing the steak and cooking it in a precisely controlled water bath before a final sear. This guarantees a perfectly even doneness from edge to edge, which can be challenging with a very thick filet.
Grilling
Smaller filets can be cooked entirely on a hot grill, though a watchful eye is needed to prevent overcooking. For a standard 8 oz filet, searing over high heat and then moving to a cooler part of the grill to finish can yield excellent results.
Pan-Sear to Oven-Finish
This is a popular restaurant technique that works well for standard and larger filets. The steak is seared in a hot pan (ideally cast iron) for a flavorful crust, then transferred to the oven to finish cooking to the desired internal temperature. This method is highly controllable and ideal for achieving a flawless finish on thicker cuts.
Conclusion: Choosing the Right Filet
Ultimately, the number of ounces in a filet mignon is not fixed, but the average cut in the US is around 8 ounces. When selecting a steak, consider your preferred portion size and how it will affect the cooking process. Smaller cuts are perfect for quick meals, while larger ones offer a more luxurious, slow-cooked experience. By understanding these variations, you can confidently choose and prepare the ideal filet mignon for your next meal.

Choosing the Right Filet Mignon Size
Consider the occasion: For a lighter meal or multi-course dinner, a 4-6 ounce filet is often sufficient. For a celebratory main course, an 8 ounce or larger cut is more impressive.
Don't overcook thin filets: Due to their delicate nature, smaller filet mignons cook very quickly. Use a meat thermometer to pull them off the heat before they reach your desired internal temperature, as they will continue to cook as they rest.
Rest your steak properly: Regardless of size, a filet mignon should rest for 5-10 minutes after cooking. This allows the juices to redistribute, ensuring a tender and moist final result.
Account for different regional sizing: If traveling or ordering from a different region, be aware that standard portion sizes can vary. In some places, a filet mignon may be much smaller than the 6-8 ounce standard in the US.
Understand the impact of bacon wrapping: Many filet mignons are wrapped in bacon. This adds flavor and fat, which can also influence the cook time. The bacon fat renders into the steak, keeping it moist.
Always use a meat thermometer: The most accurate way to gauge doneness for any steak, regardless of size, is to use a high-quality meat thermometer. This takes the guesswork out of cooking and prevents expensive mistakes.
Don't be afraid of a thicker cut: While a thicker cut requires more precise cooking methods like reverse searing, the result can be a more evenly cooked, perfect steak with a fantastic crust and buttery center.
Conclusion
While a standard filet mignon often lands in the 6-8 ounce range, with 8 ounces being a very common benchmark, the truth is that the size can vary widely. Factors like the butcher's cut, regional differences, and personal appetite all play a role. Whether you opt for a petite 4 oz cut or a more indulgent 12 oz steakhouse portion, understanding the impact of size on cooking time is key to achieving a delicious, tender, and perfectly cooked filet mignon.
