Looking for Red Robin vegetarian options? You have more to work with here than at most burger joints. Red Robin makes a real meatless patty, stocks the Impossible patty, and keeps the steak fries bottomless while you decide on the rest. The catch is for strict vegans: Red Robin moved its Impossible patty onto shared flattop grills and quietly dropped the “vegan” label, so the line between vegetarian-friendly and vegan-safe matters more here than it used to. Below you will find exactly what is vegetarian at Red Robin, what is vegan, and what to skip. If you have ever wondered what about the vegetarians, this is a chain that actually tries.
A Quick Look at Red Robin
Red Robin started in 1940 as Sam’s Tavern, a beer-and-burger spot near the University of Washington in Seattle. Owner Sam Caston liked to sing “When the Red, Red Robin Comes Bob-Bob-Bobbin’ Along,” and regulars started calling the place Sam’s Red Robin. Gerry Kingen bought it in 1969, leaned into gourmet burgers, and shortened the name to Red Robin. The bottomless steak fries and build-your-own burgers grew out of that era.
Those bottomless steak fries are still the most famous thing on the menu, and they are a big reason the chain is an easy sit-down option for families with a vegetarian at the table. Kids can build a meatless plate from apple slices, carrot sticks, broccoli, and fries, while the gourmet-burger experience keeps everyone else happy.
Today Red Robin Gourmet Burgers is a casual sit-down chain headquartered in Greenwood Village, Colorado. It has been public since 2002 (NASDAQ: RRGB) and ran about 498 restaurants at the end of 2024, roughly 91 of them franchised. With around $1.2 billion in U.S. system-wide sales, it landed at No. 48 on the 2025 Technomic Top 500 list of the country’s largest chains. Most locations are full-service, so a server can walk a meatless order through the kitchen for you.
Red Robin Vegetarian Options: What to Order
Start with a patty. Red Robin keeps two meatless options on the menu: its house ancient-grain veggie patty (a blend of grains and quinoa) and the plant-based Impossible patty. Both are vegetarian, and you can drop either one into any gourmet burger, including signature builds like the Bleu Ribbon Veggie Burger. Pile on the standard toppings — lettuce, tomato, pickle, onion, and avocado are all meat-free — and every burger comes with bottomless steak fries. Want it lighter? Swap in bottomless steamed broccoli or a house salad. Here is how the most common vegan-friendly and vegetarian menu items shake out.

Burgers and Patties: Building a Vegetarian Order
The two meatless patties are the heart of any Red Robin vegetarian order. The ancient-grain veggie patty is the classic choice and works in the Keep It Simple Veggie Burger or the Bleu Ribbon Veggie Burger. The Impossible patty gives you that closer-to-beef bite. Order either one the way you would a regular burger, then build from there.
Two things to know before you order. First, Red Robin’s default Veggie burger comes with Swiss cheese, avocado, salsa, and roasted garlic aioli, so as served it is vegetarian but not vegan — ask for no cheese and no aioli if that matters. Second, the bottomless steak fries that come with your burger are refillable, so you are never short on a side. For buns, the brioche bun, tavern bun, sesame, and ciabatta are all dairy-free, and you can go bunless with the Wedgie’s crisp lettuce wrap or a flour or spinach tortilla. The Wedgie also makes an easy vegan burger if you hold the bacon and cheese.
Bottomless Fries and Sides
Red Robin’s bottomless steak fries are the signature side, and they are vegetarian. They fry in soybean oil in a fries-only fryer, but Red Robin warns that splashback and shared vapors mean it cannot promise zero cross-contact unless you ask for the dedicated fryer. If you are vegetarian, the steak fries, sweet potato fries, and Yukon chips are all fine by ingredient. If you are vegan or avoiding meat contact entirely, ask your server to cook them in the dedicated fryer.
Skip a few sides that look meatless but are not. Garlic fries, onion rings, and the crispy onion straws all carry dairy, and the sautéed mushrooms do too. The bottomless steamed broccoli is your best vegan side — just ask for it without butter. A built-clean side salad rounds out the plate.
Salads, Sauces, and Hidden Catches
A house salad without cheese or croutons is an easy vegetarian add, and an oil-and-vinegar dressing is the one most likely to be vegan. Most of Red Robin’s creamy dressings are not vegan, so check the ingredients in the allergen tool if that matters to you. On the sauce side, salsa, guacamole, regular ketchup, mustard, BBQ, teriyaki, and marinara are all meatless picks that make the food more interesting.
Here is the catch that trips people up: Red Robin’s Smoke & Pepper Ketchup contains anchovies, which makes it not even vegetarian. Reach for the regular ketchup instead. It is a small thing, but it is exactly the kind of hidden animal ingredient worth knowing about.
What’s Vegan at Red Robin?
Eating vegan at Red Robin got harder than it used to be. The company moved the Impossible patty onto shared flattop grills, where it can touch cheese and eggs, so Red Robin no longer calls the Impossible Burger vegan. The house ancient-grain veggie patty’s egg and dairy status is not confirmed by the company either. That means there is no guaranteed-vegan burger straight off the menu, and a couple of the obvious-looking sides are non-vegan once you read the ingredients.
You can still build a reasonable vegan order. Pick the Impossible or veggie patty on a vegan bun (sesame, tavern, or ciabatta) or in a lettuce Wedgie, hold the cheese and any mayo or aioli, and add bottomless steak fries from the dedicated fryer. Salsa, guacamole, ketchup, mustard, and BBQ sauce are vegan, and bottomless broccoli without butter rounds it out. Confirm the patty and prep with the allergen calculator or your server before you order — that is the only way to be sure on a given day.
Special Dietary Requirements and Allergies
Red Robin publishes an Interactive Allergen and Nutritional Calculator on redrobin.com, and you can filter it by vegan or by specific allergens. It is the most reliable source for what is meatless on the day you visit, since menus and prep change over time and by location. For allergy orders, Red Robin trains staff to use a separate purple allergen kit to cut down on cross-contact.
A few reminders on cross-contamination. The grills and most fryers are shared with chicken and beef, so request the dedicated fryer for fries and tell your server you are vegetarian or vegan. A gluten-free bun is available, but the pretzel bun and croissant contain milk. Red Robin also does not publicly confirm whether its cheeses use animal or microbial rennet, so strict lacto-vegetarians may want to verify the ingredients before ordering cheese. When in doubt, ask the restaurant how an item is prepared.
Tips for Vegetarians at Red Robin
- Default to the ancient-grain veggie patty or the Impossible patty — both are solid vegetarian picks you can drop into any burger.
- For a vegan build, ask for a vegan bun (sesame, tavern, or ciabatta) or the lettuce Wedgie, with no cheese and no mayo or aioli.
- Order bottomless steak fries from the dedicated fryer to dodge meat cross-contact, and remember they are refillable.
- Skip the onion rings, crispy onion straws, garlic fries, and sautéed mushrooms — they all contain dairy.
- Avoid the Smoke & Pepper Ketchup; it has anchovies. Plain ketchup, mustard, salsa, guacamole, and BBQ are safe.
- Use the allergen calculator on redrobin.com before you go, and tell your server you are vegetarian or vegan so they flag the order.
- Round out the meal with bottomless steamed broccoli (no butter) and a side salad built without cheese or croutons.
Red Robin Vegetarian Options: Frequently Asked Questions
Conclusion
Red Robin is one of the friendlier burger chains for vegetarians, mostly because it bothers to make a real meatless patty and pours those steak fries without limit. Vegetarians can eat well with a veggie or Impossible burger and a clean side. Vegans can still get a good meal, but it takes a few swaps and a quick check with the allergen tool, since neither plant patty is guaranteed vegan as served.
