Denny's Veggie Patty: The Vegan Green Light
Yes, as of 2025, Denny's uses the Dr. Praeger's California Veggie Patty, which is certified vegan. This classic vegetable-based patty is made from a combination of vegetables like carrots, onions, peas, and broccoli, and does not contain any animal products. This is a key distinction from previous years when the restaurant offered other veggie patty options, including a period where the Beyond Burger was available in select locations. The switch to the Dr. Praeger's patty means a reliable, vegetable-forward option is now available nationwide for vegan diners.
How to Build a Fully Vegan Burger at Denny's
While the patty itself is vegan, a "Build Your Own" burger from Denny's is not automatically vegan. To ensure your meal is animal-product-free, you must be specific when ordering.
Start with the Base:
- The Patty: Request the veggie patty.
- The Bun: Choose either the brioche bun or the multigrain wheat bun. It is crucial to specify that you want no butter on the bun.
Customize Your Toppings:
- Exclude Animal Products: Always ask to omit cheese, mayonnaise, and any other dairy- or egg-based sauces.
- Vegan-Friendly Toppings: A wide variety of vegan toppings are available to enhance your burger:
- Lettuce
- Tomatoes
- Pickles
- Red Onions
- Fresh Avocado
- Grilled Onions
- Sautéed Mushrooms
- Sliced Jalapeños
- Vegan Sauces and Condiments: Most locations offer these vegan sauces:
- Ketchup
- Mustard
- BBQ Sauce
- Bourbon Sauce
- Salsa
The Cross-Contamination Consideration
For strict vegans, the issue of cross-contamination in a non-vegan restaurant is a serious concern. Denny's official allergen guide notes that they cannot guarantee any item is free of allergens due to shared preparation and cooking areas. Specifically, the guide mentions that their grills are seasoned with both vegetable oil and bacon. While the patty is vegan, it is likely cooked on the same surface as bacon and other meat products. For many vegans, this level of cross-contact is unacceptable. It is advisable to speak with the manager of the specific restaurant you are visiting to understand their preparation practices and whether a separate, clean cooking surface can be used.
Other Vegan Options and Sides at Denny's
Beyond the veggie burger, Denny's offers several other vegan-friendly options, with careful modifications:
- The Plant-Based Pancake Slam: Added in 2025, this includes vegan pancakes, hash browns, and seasonal fruit. Check that the hash browns are not cooked with butter.
- Hash Browns: Ask for them to be cooked in oil, not butter, and be aware of shared grill surfaces.
- Oatmeal: Request it be made with water instead of milk.
- Sides: Seasoned fries, wavy cut French fries, broccoli, fresh sautéed zucchini and squash (no butter), and seasonal fruit are typically vegan.
- Salad: A Garden Side Salad can be ordered without cheese or croutons and paired with a vegan dressing like the balsamic vinaigrette or fat-free Italian.
