The McVeggie burger from McDonald's Canada is a new plant-based burger launched nationwide in 2025 after a successful trial in select provinces. It features a breaded patty made from a blend of vegetables including carrots, peas, corn, zucchini, soybeans, broccoli, and green beans, served on a toasted sesame bun with shredded lettuce and a creamy mayo-style sauce. There is also a spicy variant with a habanero sauce. Taste reviews generally find the McVeggie patty crispy and flavorful, with an appreciated mix of vegetable textures and subtle sweetness from carrots and peas. Some reviewers liked the mayo sauce, while others noted it might not appeal to those who dislike mayo. The spicy version was regarded as a tasty option worth trying again. The sandwich is seen as substantial and reasonably priced compared to other fast food options. Nutritionally, the McVeggie contains about 470 calories, 22g fat, 11g protein, and 710mg sodium. A plant-based dietitian commented that while the protein content is a bit low for full satiety, the ingredient mix and taste are impressive. The sodium level is typical for fast food. The McVeggie is not strictly vegetarian or vegan because the patty is cooked in fryers shared with fish products and the sauces contain egg. Vegans can ask for the sandwich without mayo or habanero sauce, but cross-contact remains a concern. In summary, the McVeggie is a solid new vegetarian option at McDonald's Canada with good flavor and value, though not suitable for strict vegetarians or vegans due to preparation practices and sauce ingredients.
