Looking for Mastro’s vegetarian options? You can eat well here, but you’ll build the meal yourself from salads, sides, and a shared plate, because the dinner menus list no vegetarian entrée. This guide covers what to order, what to skip, and what to ask your server first. For more guides like it, start at the what about the vegetarians homepage.
A Quick Look at Mastro’s
Mastro’s opened in Scottsdale, Arizona, in 1999. In 2007, the private equity firms Kinderhook Industries and Soros Strategic Partners bought the group to fund an expansion. The Houston company Landry’s acquired Mastro’s in 2013 and still owns it. Wikipedia’s infobox still counts 19 locations, but Technomic’s 2026 Top 500 puts the chain at 24 U.S. units and an estimated $349 million in 2025 U.S. sales, good for rank 139.
Mastro’s runs two brands. One is Mastro’s Steakhouse, the other Mastro’s Ocean Club Seafood. Neither opens for lunch, and the dress code on the website bans beachwear, athletic apparel, hats, and tank tops. Its signature order, per its own FAQ, is the Seafood Tower, the sushi, the Prime steaks, and the Butter Cake. None of those helps a vegetarian, so you’ll lean on the side dishes.
Mastro’s Vegetarian Options: What to Order
No item on Mastro’s dinner menus carries a vegetarian label or an ingredient list, and the two menus we read don’t match, so your location may differ. We marked an item ✅ only when its name tells you it has no meat, fish, or stock. Everything else carries a ⚠️ and the reason.

Salads and Starters
The Burrata with Heirloom Tomato and Fig is the one starter that reads as meat-free on both dinner menus we opened. It’s $24 on both, so share it.
The salads need a question or two. The Chopped Iceberg Wedge, the Chopped Salad, and Mastro’s House Salad all appear on both menus, along with the Caesar and the Spicy Mambo Salad. Mastro’s prints names and prices and nothing else. Ask your server what goes in each one, and say you want no bacon, no anchovy, and no stock-based dressing.
Pass on the Wagyu Meatballs, the Bone Marrow, the Nueske’s Maple Glazed Bacon Steak, and the sushi rolls built on tuna, hamachi, lobster, or Wagyu. Skip the Lobster Bisque and the New England Clam Chowder as well.
Potatoes and Fresh Vegetables
Your main course lives here. Mastro’s groups its sides under “Potatoes & Fresh Vegetables,” and it sells them at about $16 to $20 each on the menus we read. Order three or four for the table and you’ve got dinner. Mastro’s also posts a lighter selections menu that lists Steamed Asparagus, Steamed Broccoli Florets, Steamed Spinach, and Green Beans with Sliced Almonds, which helps if you want vegetables without the sauté pan.
- Asparagus, steamed or sautéed, is the cleanest pick. A vegan directory suggests swapping the butter, so ask for that if you eat vegan.
- Garlic Truffle Cauliflower and Sautéed Broccolini are on both menus. Ask what fat the cooks use in the pan.
- Roasted Brussels Sprouts showed up on only one of the two menus, so check with your location.
- Rosemary Garlic Wild Mushrooms and Green Beans with Sliced Almonds round out the list.
- The 1 Lb Baked Potato is plain and filling. Toppings should come on the side.
The Wild Mushroom and Black Truffle Gnocchi, $30, appeared on one of the two menus. It’s the only dish that looks like a main course, so ask about the sauce and the stock before you order it.
What About the Fries?
Don’t order them. Mastro’s prints “Proudly frying with Wagyu Beef Tallow” at the top of the potatoes and vegetables section. A vegan restaurant directory lists the French-Fried Potatoes as vegan, and the chain’s own menu says otherwise. Trust the chain. Mastro’s doesn’t say whether any other side shares that fryer, so ask your server before you order anything fried.
What’s Vegan at Mastro’s?
Not much. WhatsVegan calls the vegan options at Mastro’s Steakhouse “extremely limited” and recommends avoiding the restaurant if possible. The directory suggests a baked potato or the Chopped Iceberg Wedge might work and flags the Spicy Mambo Salad as possibly containing cheese or egg. Those are the directory’s guesses, not Mastro’s word. If you eat vegan, call ahead, ask for the allergen-sensitive menu, and ask what the kitchen can do with oil in place of butter.
Special Dietary Requirements and Allergies
Mastro’s FAQ says it offers menu items for various dietary needs and allergen sensitivities, and it tells guests to ask for the allergen-sensitive menu. We couldn’t find that menu online, and Mastro’s posts no vegetarian menu either. Four things matter most for a meatless diner:
- Beef tallow. Mastro’s says it fries with Wagyu beef tallow. Ask about every fried side.
- Signature butters. Mastro’s offers Black Truffle, Bone Marrow, and Lemon Calabrese butters. The Bone Marrow butter is not vegetarian, so ask your server to leave butters off your plate.
- Stock. Soups, sauces, and gnocchi may use meat or seafood stock. Mastro’s doesn’t say.
- Menus vary by location. The two dinner menus we read differ in the soup list, the potato list, and the gnocchi. Check the menu for the restaurant you’re booking.
Tips for Vegetarians at Mastro’s
- Call ahead or write it in your reservation note, so the cooks have time to plan your plate.
- When you sit down, ask for the allergen-sensitive menu.
- Build the meal from the burrata, one salad, and three sides.
- Ask what fat goes in each sautéed side, and request oil if you can’t eat butter. Steamed vegetables from the lighter menu skip the pan.
- Pass on the fries, the soups, and any butter or sauce you can’t read.
- Don’t count on a veggie sushi roll. A vegan directory lists one, but we didn’t see it on either official dinner menu.
- Plan on dinner, since no location opens for lunch. Fort Lauderdale and Malibu serve brunch on weekends.

Conclusion
Mastro’s builds its menu for steak and seafood eaters, but you can still eat well. Order the burrata, a salad you’ve questioned, and three vegetable sides, skip the fries, and ask for the allergen-sensitive menu.
