Red Robin Grilled Veggie Sandwich: Price, Calories, Taste & Full Review

If you walk into a Red Robin and you're not in the mood for beef, the grilled veggie sandwich is the item most servers will point you toward. It's built around a grilled ancient grain and quinoa patty, stacked with fresh produce, and served the same way as every other burger on the menu: with your pick of a bottomless side. This guide breaks down what's actually in it, what it costs, how many calories you're looking at, and whether it's worth your order. We'll also walk through a copycat recipe so you can make something close to it at home.

Red Robin lists this item in its "Veggie & More" section, and it's the go-to choice for guests who want a burger-style meal without meat. Instead of a beef, turkey, or chicken patty, you get a grilled patty made from ancient grains and quinoa. It has a firmer bite than a lot of veggie patties, so it holds together well on the grill and doesn't fall apart in the bun.

The standard build keeps things simple: lettuce, tomato, sliced onion, and pickles on a toasted bun. It's meant to taste like a real sandwich, not a diet substitute, and Red Robin treats it with the same toppings menu as its beef burgers. That means you can load it up with cheese, avocado, grilled mushrooms, or any of the sauces used across the gourmet burger lineup if you want more flavor.

It's also worth knowing this patty is the same one used across Red Robin's other veggie-friendly builds, including their veggie patty menu options, so if you like this sandwich, you have a few other ways to order the same base.

Pricing at Red Robin changes a bit by state and city, but as of September 2026 the grilled veggie sandwich typically runs between $8.99 and $13.29. The lower end is closer to what you'll pay if you order it as a straightforward build-your-own sandwich, while the higher end reflects locations where prices run a little steeper or where you've added a few extras.

Every burger and sandwich order, including this one, comes with your choice of one bottomless side. Popular picks are the Bottomless Steak Fries, sweet potato fries, or a side salad if you'd rather keep the meal lighter. Because the fries are bottomless, you can ask for a refill without paying extra, which is one reason regulars keep coming back to this chain even though a single sandwich isn't the cheapest option on paper.

Here's the honest take. The ancient grain and quinoa patty has a mild, slightly nutty flavor on its own, so it leans on toppings and sauce for most of its personality. Grilled the way Red Robin does it, the outside gets a light char that adds some smokiness, while the inside stays soft rather than mushy, which is a common complaint with cheaper veggie patties.

On its own with just lettuce, tomato, and onion, it's fine but a little plain. Where it really works is when you treat it the way you'd treat a beef burger and add real toppings. Cheese helps a lot here, and so does a smear of the campfire sauce or a garlic aioli. Guests who've tried it with grilled onions and pepper-jack say it's easy to forget you're eating a vegetarian sandwich at all.

Red Robin lets you build this sandwich the same way you'd build any of its tavern burgers, so the extras list is long. A few of the most popular add-ons include:

• Cheese: American, Swiss, cheddar, or pepper-jack
• Bacon: regular or candied, if you're not keeping it fully vegetarian
• Fresh smashed avocado: adds creaminess without overpowering the patty
• Grilled onions or mushrooms: boosts the smoky, savory side of the sandwich
• Sauces: campfire sauce, garlic aioli, or classic mayo and mustard
• Bun swaps: lettuce wrap instead of a bun, or a gluten-free bun for a small upcharge

Each extra adds a small fee, usually somewhere between $0.50 and $2.00 depending on the item, so a fully loaded version of this sandwich can end up closer to $15 once you add cheese, bacon, and avocado together. If you want a lighter version instead, ask for it without cheese or mayo and pair it with a side salad from the salad menu instead of fries.

The patty by itself comes in at roughly 370 calories, which is lower than the beef patty option on the same build-your-own menu. Once you add the bun, lettuce, tomato, onion, and pickles, the full sandwich typically lands somewhere between 560 and 650 calories, depending on the exact bun and sauce used at your location.

Keep in mind that your side counts separately, and it usually adds the most to your total. A regular order of steak fries can add several hundred calories on its own, while a side salad without heavy dressing keeps the meal noticeably lighter. If you're watching your intake, swapping fries for broccoli or a small side salad is the easiest change you can make without touching the sandwich itself.

For guests avoiding meat, dairy, or gluten, here's a quick cheat sheet:

• Vegetarian: yes, as served
• Vegan: possible if you skip cheese, mayo-based sauces, and confirm the bun
• Gluten-free: ask for the gluten-free bun or a lettuce wrap

If you're vegetarian, this is one of the better sit-down burger options you'll find at a chain like Red Robin, mainly because the patty is built to hold up on a grill instead of falling apart like a lot of frozen veggie patties do. It's also nice that you get the exact same toppings, sauces, and bottomless sides as every meat-based item on the menu, so you're not stuck with a stripped-down version of the meal everyone else is having.

Where it falls short is flavor on its own. If you order it plain, expecting something as punchy as a beef burger, you might walk away thinking it's just okay. The move is to treat it like a blank canvas: add cheese, a sauce you like, and maybe grilled onions, and it holds its own next to any burger on the menu. For a family table where one person eats vegetarian and everyone else doesn't, it's an easy order that doesn't feel like an afterthought, which also makes it a solid pick off the shared appetizers and mains people usually build a table around.

Want to make something close to this at home? Here's a simple, from-scratch version using an ancient grain and quinoa base, grilled the same way Red Robin does it.
