Sweet Potato Cauliflower Taco Ingredients

Sweet Potato- I love sweet potatoes! Sweet and savory all at once, they add meatiness to these tacos. You can use yams if you are unable to find sweet potatoes.

Cauliflower- Something great happens to cauliflower when you roast it, and it takes on the seasoning blend beautifully! You can use a head of cauliflower and chop it, or buy it bagged already cut (more on that in the recipe notes)

Poblano Chile- Also known as Pasilla Chile, these large dark green mild chiles are so good roasted, and provide a bit more kick than a bell pepper. 

Onion- I like yellow onion here for its sweetness!

Salt and Pepper- You won’t need a lot, the rest of the spices do most of the work here!

Cayenne Pepper- Don’t get too heavy handed, unless you want some really spicy tacos! A little goes a long way.

Paprika- You can use any Paprika here that you have, whether its smoked or hot (if it’s hot Paprika use a little less).

Cumin- I love the citrusy and smoky flavor of Cumin, and it is perfect in this recipe.

Ancho Chile Powder- Ancho is fruity and smoky, and my go to chili powder! If you don’t have Ancho, you can use whatever chili powder you have on hand.

Oregano- This adds an herbaceous quality, even though we are using dried instead of fresh. Try to use Mexican Oregano if you can find it.

How To Make Sweet Potato Cauliflower Tacos

How To Meal Prep Tacos

This recipe is made for meal prep. All you really need to do is make the vegetables ahead of time and put them in whatever storage containers you use to store your make ahead meals and reheat when ready. The taco filling will keep refrigerated for up to one week.

To reheat, simply microwave until warm. I like to add the taco filling to my tortilla first, that way both the filling and the tortilla are warm.

The vegetables can be roasted and stored for up to a week in advance, making this a great option for making meals ahead!

What To Serve With Sweet Potato Cauliflower Tacos

I love these tacos with crunchy purple cabbage for extra color, and some Cotija cheese on top. Here are some other options:

As far as side dishes, rice and beans are great! You can also try my recipe for Sopa De Lima.

Recipe Variations

If you want to add some protein but still keep these meatless, then try black or pinto beans. To add meat as part of the filling, cooked chorizo or shredded pork, beef, or chicken would be great as well.

If it’s in season, fresh corn cut right off the cob and added as a topping is wonderful as well. To add extra depth, grilled corn is wonderful on these tacos too!

Sweet Potato Cauliflower Tacos

Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes

Sweet Potato Cauliflower Tacos are spicy and flavorful! These Vegetarian tacos cooked on a sheet pan in almost no time, and are great for meal prep!


  • 1 medium sized Sweet Potato
  • 1/2 pound of Cauliflower florets
  • 1 Poblano Chile
  • 1/2 of a Yellow Onion
  • 2 Tbsp of Avocado Oil
  • 1 1/2 tsp of Salt
  • 1/8 tsp of Cayenne Pepper
  • 1/2 tsp of Black Pepper
  • 1/2 tsp of Paprika
  • 1/2 tsp of Cumin
  • 1 tsp of Ancho Chile Powder
  • 1 tsp of Dried Oregano


  1. Turn the oven on to 425 degrees and line a rimmed baking sheet with aluminum foil (this is optional, but it makes cleanup so much easier).
  2. Peel and cut the sweet potato into a half inch dice. Try to make the pieces of similar size for even cooking.
  3. Trim down the cauliflower florets if they are really large so that they will cook evenly with the sweet potatoes. They don't have to be the same size as the potato chunks because the cauliflower cooks a bit faster.
  4. Cut the top off the poblano chile and remove the seeds and cut in half.
  5. Slice the half an onion into slices about a quarter of an inch thick.
  6. Place all the vegetables onto the baking sheet and assemble the spiced mixture. Toss with the 2 Tbsp of oil.
  7. In a small bowl, combine the 1 1/2 tsp of salt, 1/2 tsp of black pepper, 1/8 tsp of cayenne pepper, 1/2 tsp of paprika, 1/2 tsp of cumin, 1 tsp of ancho chile powder, and 1 tsp of dried oregano. Stir well.
  8. Sprinkle the spice blend over the vegetables and stir to coat everything nicely.
  9. Roast until the sweet potatoes are easily pierced with a fork and the cauliflower is golden brown, about 20 minutes. After 10 minutes, turn the poblano chile halves over to finish roasting and check on the veggies. Roast for 10 more minutes and check again. Spoon into tortillas, add your favorite toppings and serve!


If you don't want the extra heat from the poblanos, you can substitute green bell pepper.

For less heat in the spice blend, regular chili powder in place of the ancho will be more mild.

Fresh corn, red cabbage, and cotija cheese are great toppings.

If you want to add protein, try pinto or black beans.

Chicken, pork, shrimp, or beef would all be great options if you want to add meat.
