Introduction

Flank steak often flies under the radar compared to ribeye or filet mignon, yet it remains one of the most nutrient-dense cuts of beef you can put on your plate. Known for its bold flavor and lean profile, flank steak appeals to athletes, health-conscious eaters, and home cooks looking for high-quality protein without excessive fat. Understanding flank steak nutrition can help you decide how it fits into a balanced diet and how to prepare it for maximum health benefits.

This guide explores calories, protein content, vitamins, minerals, and real-world tips for enjoying flank steak as part of a healthy lifestyle.

What Is Flank Steak?

Flank steak comes from the abdominal muscles of the cow, an area that gets significant use. Because of this, the cut is lean and flavorful but slightly tougher than premium steaks. When cooked correctly and sliced against the grain, flank steak becomes tender and satisfying.

Its nutritional value makes it a popular choice in cuisines around the world, from fajitas and stir-fries to grilled steak salads.

Flank Steak Nutrition Overview

Flank steak is prized for its high protein content and relatively low fat compared to many other beef cuts. A typical cooked serving of flank steak (about 3 ounces or 85 grams) provides a strong nutritional foundation.

Calories in Flank Steak

A 3-ounce cooked serving of flank steak contains approximately 160–170 calories, depending on trimming and cooking method. This moderate calorie count makes it suitable for both weight maintenance and weight-loss plans when portion sizes are controlled.

Protein Content

Protein is the standout nutrient in flank steak. The same serving delivers around 23–25 grams of high-quality protein, supporting muscle repair, satiety, and metabolic health.

Fat and Cholesterol

Flank steak is considered a lean cut of beef. It typically contains:

• About 6–8 grams of total fat
• Roughly 3 grams of saturated fat
• Around 70 mg of cholesterol

Compared to fattier cuts, flank steak offers robust flavor with less overall fat.

Vitamins and Minerals in Flank Steak

Beyond protein, flank steak nutrition includes essential micronutrients that play critical roles in everyday health.

Iron for Energy and Blood Health

Flank steak is a rich source of heme iron, the most easily absorbed form of iron. Adequate iron intake supports oxygen transport in the blood and helps prevent fatigue, particularly in active individuals and women.

Zinc for Immunity

Zinc supports immune function, wound healing, and hormone production. A single serving of flank steak can provide a significant portion of daily zinc needs.

B Vitamins for Metabolism

Flank steak contains several B vitamins, including:

• Vitamin B12, essential for nerve function and red blood cell formation
• Vitamin B6, which supports brain health and protein metabolism
• Niacin (B3), important for energy production

These nutrients contribute to sustained energy levels throughout the day.

Selenium and Phosphorus

Flank steak also provides selenium, an antioxidant mineral that supports thyroid function, and phosphorus, which is vital for bone health and cellular repair.

Health Benefits of Flank Steak

When eaten in moderation and prepared thoughtfully, flank steak offers several health advantages.

Supports Muscle Growth and Recovery

Thanks to its high protein content and complete amino acid profile, flank steak is ideal for muscle repair after workouts. Many athletes include it in post-training meals for recovery and strength gains.

Helps Maintain a Healthy Weight

Lean protein promotes fullness and helps regulate appetite. Including flank steak in balanced meals may reduce unnecessary snacking and support long-term weight management.

Promotes Heart Health (When Prepared Properly)

While red meat has been debated in nutrition circles, lean cuts like flank steak can fit into a heart-conscious diet. Choosing grilling, broiling, or pan-searing with minimal oil helps keep saturated fat intake in check.

Prevents Nutrient Deficiencies

Iron, zinc, and vitamin B12 deficiencies are common worldwide. Regular inclusion of nutrient-dense foods like flank steak can help bridge these gaps.

Flank Steak vs Other Steak Cuts

Understanding how flank steak nutrition compares to other cuts can clarify why it stands out.

Flank Steak vs Ribeye

Ribeye is significantly higher in calories and fat. While flavorful, it may not suit those seeking lean protein. Flank steak provides similar protein with fewer calories.

Flank Steak vs Sirloin

Sirloin is also lean and nutritious, but flank steak often contains slightly more protein per calorie and a stronger beef flavor.

Flank Steak vs Skirt Steak

Both cuts come from the abdominal area, but skirt steak typically has higher fat content. Flank steak is leaner and slightly higher in protein.

How Cooking Methods Affect Flank Steak Nutrition

Cooking technique plays a major role in preserving the nutritional value of flank steak.

Best Cooking Methods

Healthier cooking options include:

• Grilling over medium heat
• Broiling in the oven
• Pan-searing with minimal oil
• Stir-frying with vegetables

These methods maintain protein quality without adding unnecessary calories.

Avoid Overcooking

Overcooking can make flank steak tough and reduce moisture. Medium-rare to medium doneness preserves texture and flavor while maintaining nutrients.

Marinating for Better Digestion

Marinating flank steak with acidic ingredients like lemon juice or vinegar can improve tenderness and may enhance mineral absorption.

How to Include Flank Steak in a Healthy Diet

Flank steak fits well into a variety of meal plans when paired with wholesome sides.

Balanced Meal Ideas

These combinations provide fiber, vitamins, and sustained energy.

Portion Control Tips

Stick to 3–4 ounces per serving to enjoy nutritional benefits without excessive calorie intake. Pairing steak with vegetables helps create volume without extra calories.
