Sheet Pan Summer Roasted Vegetable Tacos


I’ve been struggling with what plant-based dinner options this summer. It feels like we’ve been in a heatwave for weeks! With all this heat, we’ve been leaning on our bbq for most of our dinner prep. Our go-to bbq meals usually revolve around meat, making meatless Mondays a challenge these days.


Tacos are always a great simple meal option and can be easily made plant-based. I created this summer roasted vegetable taco recipe for a tasty plant-based dinner that can be cooked in the oven or on the bbq to increase our intake of plant protein this summer.

These Sheet Pan Summer Roasted Vegetable Tacos are loaded with veggies, making them a balanced meal all on their own. I used bell pepper for some subtle sweet flavour, jalapeno for a little spice, and cauliflower for some substance. I also used corn which adds a sweet flavour and is such a staple for me in summer meals.


The protein source for this taco recipe is crispy roasted lentils. I love roasting lentils because they get crispy and add a delicious crunch to this taco recipe. You’ll need to boil the lentils before roasting or use canned lentils to save about 20 minutes of additional prep.


Nutrition tip: if you’re using canned lentils, be sure to give them a good rinse and pat dry to help reduce the added sodium content.

How to make it: 


To make this recipe, prepare your vegetables by dicing the bell pepper and jalapeno pepper. Remove the seeds from the jalapeno pepper if you don’t like spice! Cut your cauliflower into small bite-sized florets. Cauliflower takes the longest to roast, so be sure to cut the pieces small so that they will cook at the same time as everything else.


I used frozen corn for this recipe out of convenience. Simply thaw frozen corn by running it under hot water in a strainer and pat dry.


Assemble your sheet pan by layering all of the veggies along with the cooked lentils. Drizzle the sheet pan with oil and season with salt and pepper, to taste, and the remaining spices. Stir to combine. If you’re cooking this mixture in the oven, it will bake for about 20 minutes at 425.


You can cook this recipe in the oven or on the BBQ. Note: if you’re using a sheet pan on the bbq, cooking time may vary. You’ll also want to use an older sheet pan as it may get a bit burnt.


mango, avocado, red onion


Meanwhile, you can prepare your toppings so that you’re ready to go once the sheet pan mixture is cooked. For toppings, I used feta cheese, sliced mango and thinly sliced red onions. I loved this combination of salty and sweet!


And of course, avocado. In my opinion, you can’t have tacos without some avocado. For this recipe, you can add sliced avocado as a topping, or mash your avocado with cilantro (I used paste), lime juice, and a bit of salt for an added layer of flavour!
