Mastro’s Steakhouse maintains consistent standards across locations, yet each cut of meat tells a different caloric story. If you are tracking your intake, understanding Mastro’s Steakhouse Nutrition and Calories before you arrive is the smartest way to enjoy a premium dinner without derailing your goals. The menu is large, but the numbers behind the steaks, sides, and sauces are not a mystery.
You do not need to guess. You need a practical breakdown of what fits your daily allowance and what might be a splurge. This guide gives you the real figures for popular dishes, so you can order with confidence.
Mastro’s Steakhouse Nutrition And Calories: The Core Cuts
Steak is the centerpiece here, but not all cuts are equal. A lean filet is a completely different nutritional profile than a bone-in ribeye. Here is how the main steaks compare based on standard 10-ounce portions, cooked without extra butter on top.
Filet Mignon (8 Oz)
- Calories: Approximately 480-550
- Protein: 45-50g
- Fat: 30-35g
- Carbs: 0g
This is your best option for a high-protein, lower-calorie meal. Ask for it dry (no basting butter) to save an extra 100-150 calories.
Bone-In Ribeye (18 Oz)
- Calories: Approximately 1,100-1,300
- Protein: 90-100g
- Fat: 85-95g
- Carbs: 0g
This is a massive portion. If you eat the whole thing, you are consuming nearly a full day’s worth of fat. Consider splitting this or taking half home for lunch tomorrow.
New York Strip (12 Oz)
- Calories: Approximately 700-800
- Protein: 65-70g
- Fat: 50-55g
- Carbs: 0g
A middle ground option. It is richer than the filet but less fatty than the ribeye. The marbling gives flavor, but you pay for it in saturated fat.
Steak Toppings And Add-Ons
Be careful here. The steak itself is only half the story. The sauces and toppings are where calories hide.
- Oscar Style (Crab + Asparagus + Hollandaise): Adds 300-400 calories
- Blue Cheese Crust: Adds 250-350 calories
- Sauteed Mushrooms: Adds 150-200 calories (cooked in butter)
- Bernaise Sauce (Side): Adds 350 calories
If you want to keep the meal lean, order the sauce on the side and use it as a dip, not a pour.
Appetizers And Their Caloric Load
Before the steak, you might look at the starters. These are often the most calorie-dense items on the entire menu. A salad might seem safe, but the dressing changes everything.
Mastro’s Chopped Salad
- Calories: 650-750 (with dressing)
- Protein: 15-20g
- Fat: 50-60g
This is a shareable portion. If you eat the whole bowl yourself, you are adding a significant amount of fat before your steak even arrives. Ask for the dressing on the side and use half.
Jumbo Lump Crab Cake
- Calories: 450-550
- Protein: 25-30g
- Fat: 35-40g
Most of the calories here come from the mayonnaise binder. It is a tasty treat, but not a light one.
Spicy Tuna Tartare
- Calories: 380-450
- Protein: 30g
- Fat: 20g
This is a better pick if you want seafood. The avocado and sesame oil add healthy fats, but the portion is still generous.
Sides To Share Or Skip
Mastro’s sides are famous for being massive. They are meant for the whole table. If you order one for yourself, you are consuming three to four servings in one sitting.
Baked Potato (Loaded)
- Calories: 550-650
- Protein: 12g
- Fat: 30g
This includes butter, sour cream, and chives. It is a carb bomb that will spike your blood sugar. If you want a potato, get it plain and add just a little salt and pepper.
Sauteed Spinach
- Calories: 300-400
- Protein: 5g
- Fat: 30g
Do not be fooled by the green color. This spinach is cooked in a lot of butter and garlic oil. It is not a low-calorie vegetable dish. It is a fat delivery system.
Mastro’s Mac & Cheese
- Calories: 800-1,000 per full order
- Protein: 25g
- Fat: 60g
This is one of the most popular sides, but it is also one of the heaviest. A single serving (1/4 of the dish) is roughly 200-250 calories. Share it with four people minimum.
Desserts And Liquid Calories
The dessert menu is dangerous. The signature Butter Cake is a massive portion. You should also check what you are drinking, because cocktails can add 300-500 calories before you even eat.
Butter Cake
- Calories: 1,200-1,400 per full order
- Protein: 15g
- Fat: 60g
- Carbs: 150g+
This is meant for two to three people. Even a small slice will set you back 400 calories. It is delicious, but it is a rare treat, not a regular habit.
Signature Cocktails
- Mastro’s Margarita: 350-450 calories
- Old Fashioned: 250-300 calories
- Glass of Wine (6oz): 120-150 calories
Alcohol is empty calories. If you are having a steak and a side, adding two cocktails can push your total meal over 2,000 calories. Stick to wine or sparkling water with lime if you are counting.
Practical Tips For A Lighter Meal
You can eat at Mastro’s and stay within your calorie budget. It just takes a little planning. Here is a step-by-step approach to ordering smart.
- Skip the bread basket. The sourdough is good, but it adds 200-300 calories before your meal starts.
- Order a filet (8 oz) cooked medium rare. This is the leanest cut on the menu.
- Request no basting butter. Ask them to cook it in a dry pan or with minimal oil.
- Choose a simple side. Steamed asparagus (ask for no butter) or a plain baked potato are your best bets.
- Get all sauces on the side. Control how much you use. A tablespoon of sauce is 50-100 calories, but a full ladle is 300+.
- Split everything. The portions are huge. Sharing a steak and a side with a friend cuts your calories in half.
- Drink water or unsweetened tea. This saves you 300-500 calories compared to cocktails.
