There’s something so absolutely delicious about a homemade roasted veggie burger—the kind made from real vegetables you can see and taste, not something mysterious pulled from a freezer box. This harvest veggie burger is exactly that: hearty, savory, and packed with layers of flavor from simple, everyday ingredients.
It all starts with a flavorful base of shallots, onions, and garlic, roasted until tender, slightly browned and fragrant. From there, mushrooms step in to add that rich, umami depth that makes veggie burgers feel just as satisfying as their meat-based counterparts. Finely chopped Brussels sprouts, carrots, and spinach bring a subtle earthiness and a boost of rainbow goodness, while fresh parsley brightens everything up.
To give these burgers substance and structure, black beans, toasted walnuts, and cooked rice are folded in, creating a tender-but-hearty texture that holds together beautifully. A handful of panko breadcrumbs keeps the patties light rather than dense, and a thoughtful blend of spices ties all the flavors together—savory, well-seasoned, and anything but bland. Here is where you can add some creativity of your own, by adding whatever spices you love best.
Once formed, these veggie burgers cook up with a lightly crisp exterior and a soft, satisfying center. They’re sturdy enough for a bun but just as good served open-faced, tucked into a pita, or plated alongside a big salad. Add your favorite toppings—melty cheese, avocado slices, caramelized onions, or a mound of shredded cabbage and you’ve got a meal that even non-vegetarians will happily devour.
What I love most about this recipe is how adaptable it is. It’s a great way to use up extra vegetables, it can be made ahead, and the cooked patties freeze beautifully for easy weeknight meals. Whether you’re cooking for a meatless Monday, a vegetarian crowd, or simply craving something wholesome and homemade, this veggie burger delivers big on flavor and comfort.
This is the kind of veggie burger that reminds you why homemade is always worth it—real ingredients, bold flavor, and a satisfying bite every time. 🌱🍔
Roasted Veggie Burger
Ingredients
- 1 whole yellow onion (coarsely diced)
- 2 whole shallots (sliced or diced)
- 1 large clove garlic (minced)
- 1 head cauliflower
- 1/2 bunch broccoli
- 2 whole carrots (peeled and cut into 2-inch pieces)
- 16 oz. cremini mushrooms (cleaned and quartered)
- 10 whole Brussels sprouts (finely sliced or shredded)
- 1 cup cooked brown rice
- 14 oz. canned cannellini or black beans (drained)
- 1/2 tsp. ground pepper
- 1/2 tsp. salt
- 1/2 tsp. lemon pepper paradise (or your favorite lemon pepper)
- 1/2 tsp. paprika
- 1/2 cup walnuts or pecans (toasted)
- 2 cups arugula
- 1/3 cup parsley leaves
- 1/2 cup panko
- 2 large eggs
- 6 slices cheese of your choice
Instructions
- Preheat oven to 425℉. Spray a large baking sheet with cooking spray.
- Clean veggies and cut into small chunks. Toss with olive oil and season with lemon pepper, paprika, salt and pepper.
- Arrange the veggies on a pan, organizing them into fast-cooking and slower-cooking varieties. For example, put onions, shallots, broccoli, carrots together, and mushrooms and chopped Brussels sprouts together. This makes it easier to remove veggies from the baking sheets as they cook for different lengths of time.
- Bake veggies for 10-20 minutes, depending upon the veggie, until the veggies are tender to al denté and nicely browned. Remove from oven and cook completely.
- Meanwhile, blend nuts, panko, arugula and and parsley to a fine crumb in a food processor. Remove to a bowl. No need to wash the bowl of the processor at this point.
- When veggies are cool, add them to the processor and process until well chopped, but not puréed. Remove mixture to a mixing bowl. Add the beans, rice and egg. Blend well. Finally, stir in the panko mixture.
- Preheat a skillet or griddle and brush with olive oil.
- Form mixture into 6 balls. Place them on a preheated griddle. Flatten them into a patty with a flat metal or plastic spatula. Sear both sides to the patty on medium-high to get a nice brown color, then lower heat to low. Continue to cook until heated all the way through. Lay a slice of your favorite cheese on top and cook until cheese is melted.
- Once the cheese is melted, serve them with or without a bun, but be sure to add your favorite toppings!
