Ingredients

FOR SPECIAL SAUCE

  • 1/4 cup sour cream
  • 2 tablespoons ketchup
  • 1/8 teaspoon cayenne
  • 1 teaspoon lime juice
  • Lots of black pepper
  • pinch of salt
  • 2 tablespoons fresh cilantro
  • 1 tbsp water, if need be

TO ASSEMBLE BURGER (each burger)

  • 1 veggie patty favorite store-bought
  • 1 slice cheese
  • 1 brioche bun toasted
  • few slices red onion
  • 1-2 butter lettuce leaves
  • 2 sliced tomatoes
  • 2 tablespoons special sauce spread on each side

Instructions

STEP 1 - MAKE THE SPECIAL SAUCE

  • Special Sauce. Add all the special sauce ingredients in a small bowl  - sour cream, ketchup, cilantro, salt, black pepper, cayenne pepper, lime juice, and water - if need be. Mix well. Adjust the consistency as needed.

STEP 2 - BAKE PATTY & TOAST BREAD

  • Bake Patty. Grab your favorite frozen patty. Here I'm using Trader Joe's Quinoa Cowboy Veggie Burger. Place the patty in a toaster oven and follow the instructions on the box. I like my veggie patty crispy so I decided to air fry it for 8-10 minutes. Once baked, add a slice of cheese. Close and bake for another 2 minutes. Your cheesy veggie patty is ready. Set aside. Next, toast a bricohe bun.

STEP 3 - ASSEMBLE BURGER

  • Assemble Burger. Open the burger buns. Add a generous layer of special sauce on both sides. Place the cheesy patty on top, followed by sliced pickles. Now add sliced red onion. Top with butter lettuce. Top with sliced tomatoes. Top with the other half of the bun and enjoy!

Notes

This recipe was first published on October 23, 2010, and has been modified and updated since.
  • Bun - Instead of a brioche bun, you may use a whole wheat bun, ciabatta bun, or sandwich bread. For a healthier option, opt for whole wheat bread which contains more protein and fiber.
  • Veggie Burger Suggestions - I also love Trader Joe's Masala Burgers, Dr. Praeger's California Veggie Burger, and Morningstar Farms Garden Veggie Burger. Choose your favorite patty - vegetarian or non-vegetarian.
  • Sour Cream - You may substitute Greek yogurt for sour cream for the special sauce. If you prefer mayo, that works too.
  • Cheese - For this recipe, I used Colby Jack Cheese, however you may use any cheese you like. I recommend cheddar, smoked cheddar, smoked gouda, havarti, muenster, or pepper jack. Additionally, you may skip cheese too.
  • Vegan - Make sure you choose a plant-based patty and bread. You can substitute vegan sour cream and cheese.
  • Gluten-free - Use a gluten-free patty or bread. The rest of the ingredients are naturally gluten-free.
