Understanding the Standard Serving Size
For many brands, the standard recommended serving size for extra firm tofu is 3 ounces, which is equivalent to about 85 grams. A typical 14-to-16-ounce block of extra firm tofu therefore contains between four and five servings. This standardized measurement makes it easy to incorporate into recipes and track for dietary purposes. It is important to note that nutritional values can vary slightly between brands, so always check the product's nutrition label.
Measuring a Serving of Extra Firm Tofu
Measuring extra firm tofu can be done in a few straightforward ways to ensure you get the correct portion for your meal.
By Weight
For the most accurate measurement, use a kitchen scale. Simply place the pressed tofu on the scale and cut off an 85-gram portion. This is especially helpful if you are calorie-counting or need precise protein measurements.
By Block Proportions
Without a scale, you can use visual estimation. Since a standard 14- to 16-ounce block contains roughly 4 to 5 servings, a good rule of thumb is to cut the block into four or five equal pieces. A 14-ounce block cut into five pieces will result in approximately 2.8-ounce servings, which is very close to the standard 3 ounces. This method works well for meal prep and general cooking.
By Volume (After Crumbling)
For recipes that call for crumbled tofu, like vegan "scrambled eggs" or taco filling, measuring by volume is practical. A 16-ounce block of crumbled tofu yields about 1.5 cups. A quarter-cup of this crumbled tofu could be considered a partial serving, but weighing is best for accuracy.
Nutritional Breakdown of an Extra Firm Tofu Serving
Beyond just the portion size, the nutritional content of that 85-gram serving is what makes extra firm tofu a valuable addition to many diets. Here's a typical nutritional profile based on various brands:
- Calories: Approximately 80-90 calories
- Protein: Around 8-9 grams
- Fat: Roughly 4.5-5 grams
- Carbohydrates: Typically 2 grams or less
- Fiber: About 1-2 grams
- Sodium: Minimal, often 10-15 mg
- Calcium: A significant source, sometimes providing 10-20% of the daily value
- Iron: Also a good source, providing around 8-15% of the daily value
This robust nutritional profile demonstrates why extra firm tofu is a powerhouse of plant-based protein, minerals, and healthy fats.
Preparing Your Tofu Serving for Maximum Flavor
One of the most important steps for cooking extra firm tofu is pressing it to remove excess water. This helps it absorb marinades more effectively and achieve a firmer, crispier texture when cooked.
Here’s a simple process for preparing a serving:
- Pressing: Remove your 3-ounce portion from the block and wrap it in a few paper towels or a clean dish towel. Place something heavy, like a few heavy cans or a cast iron skillet, on top and let it press for at least 30 minutes.
- Freezing (Optional): For an even chewier, meatier texture, you can freeze your tofu. After pressing, freeze the portion in a freezer-safe bag. Once thawed in the fridge, press it again. The freezing process creates ice crystals that expand and create a more porous texture.
- Marinating: Extra firm tofu has a very mild flavor on its own, making it a blank canvas for marinades. After pressing, marinate your serving for at least 30 minutes to infuse it with your desired flavor.
- Cooking: Pan-fry, bake, air-fry, or grill your prepared tofu. For a crispy finish, a non-stick or cast iron pan works best. Leave the tofu undisturbed for several minutes to allow a golden crust to form.
Comparison of Tofu Firmness and Protein Content
| Tofu Type | Best Uses | Approx. Protein per 3 oz (85g) | Key Characteristic |
|---|---|---|---|
| Silken | Creamy dips, sauces, smoothies | 4 grams | Very soft, custard-like, high water content |
| Soft | Miso soup, scrambles, delicate dishes | 5-6 grams | More texture than silken, still delicate |
| Firm | Soups, skewers, sautés | 8 grams | Good for absorbing marinades, holds shape fairly well |
| Extra Firm | Stir-fries, baking, grilling, frying | 8-9 grams | Very dense, meaty texture, holds shape well |
| Super Firm | High-protein dishes, grilling, baking | 11 grams | Pre-pressed, no draining needed, densest texture |
How to Incorporate a Serving of Extra Firm Tofu into Your Meals
A single serving of extra firm tofu is incredibly versatile. Here are some ideas for incorporating it into your diet:
- Stir-Fry: Cut your serving into cubes or triangles and pan-fry until golden brown. Toss with your favorite vegetables and sauce.
- Baked: Coat cubed tofu in cornstarch and spices, then bake at a high temperature until crispy. Add to salads, grain bowls, or pasta dishes.
- Grilled: Marinate thick slices or skewers of tofu and grill until you get distinct grill marks and a smoky flavor.
- Scramble: Crumble the tofu with a fork, season with turmeric for color, and pan-fry with veggies for a delicious vegan scramble.
- Sandwich Filling: Pan-fry a thin slice of tofu and use it as a protein-packed alternative to meat in sandwiches and wraps.
This versatility makes extra firm tofu an excellent choice for a wide variety of meals, from quick weeknight dinners to more elaborate culinary creations.

Conclusion
In conclusion, one serving of extra firm tofu is typically defined as 3 ounces (85 grams), and it packs a powerful nutritional punch of protein, calcium, and iron for a relatively low number of calories. By understanding this standard serving size, you can accurately plan your meals and track your intake. The key to making it a delicious and satisfying addition to your diet lies in the preparation—namely, pressing it to remove excess water and exploring various cooking methods like baking, grilling, and pan-frying. With its dense and meaty texture, extra firm tofu serves as a versatile and healthy canvas for a wide array of recipes, proving that plant-based eating can be both nutritious and flavorful.
