Ultimate Veggie Burger Sandwich with a special sauce tastes amazing with your favorite store-bought veggie patty. My sauce is an Indian-inspired spin on In-N-Out’s special sauce. This delicious meal takes 15 minutes to prep and is perfect for a quick and easy meal.

I always keep frozen veggie patties on hand. I love them, and my son loves them too! Let’s face it, there are days when we don’t feel like cooking and on such days I love a semi-homemade meal. Choose your favorite veggie patty and build your burger how you like it.
I paired the burger with a sauce that tastes similar to In-N-Out’s special sauce. Years ago when I first tried In-N-Out, I tried to replicate their sauce, but I ended up with something similar, not quite exact.
Hope you guys give this recipe a try when you don’t feel like cooking. If you are in the mood to cook, try my Sweet Potato Black Bean Burgers with Chipotle Aioli – they’re high in protein and nutritious.

Ingredients

- Veggie Patty/Burger – Use your favorite store-bought veggie burger. I love the Trader Joe’s Quinoa Cowboy Veggie Burger – you can also use their Masala Burger. I place the burger in an air fryer for crispy results for 10 minutes.
- Cheese – I love Colby Cheese for this recipe, however feel free to use cheddar, Pepper Jack, Havarti, or muenster.
- Bun – A buttery Brioche bun tastes amazing with this patty.
- Special Sauce – The ingredients for the special sauce are in the recipe card below.
*See the recipe card below for full information on ingredients and quantities.*
Substitutions/Variations
- 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.

Even my meat loving husband enjoyed these. We grilled them outside and they tasted amazing.
@Sherry – Oh, I wish you had used cilantro, but I'm sure it tasted great with basil too. Dr. Praeger's ROCKS!
This was amazing. Luckily, I had Dr. Praeger's on hand. I didn't have fresh cilantro, so I used fresh basil instead and it tasted great. I would love to try it with cilantro, though.
i'm not always very creative when it comes to veggie burger toppings, but this looks great 🙂 also sorry it broke on you 🙁 that happens to me a lot too. i microwave them and when i flip them sometimes they fall apart. it's so sad hehe.i'll admit that i don't really enjoy exercise. when i do i feel great and am glad i did it, but eventually i get lazy and just stop doing it. and then i dread the day i start again, it's a crazy cycle, really 😛
Thanks Prazzie… I was thinking about getting Wii Fit, but wasn't sure. It may not be a bad investment for those lazy cold winter days of going to the gym. Hope you enjoy this sandwich.
I'm going to have to give this a try.
I started exercising again last week using Wii fitness games. I generally enjoy it, but I find running really boring when I use EA Sports Active. Running on Wii Fit Plus is more fun. I couldn't go to a gym, though, I find that excruciatingly dull. As soon as the weather plays along, I'd love to go running on the beach.
Wow, it looks so good Nish…I wanna try one day!
