Arrange 7 cups cauliflower on a large rimmed baking sheet. Drizzle with 3 tbsp olive oil and sprinkle with 2 tbsp taco seasoning . Toss to combine and arrange cauliflower in a single layer.
Bake for 15 minutes. Remove from oven and flip florets over. Continue to bake, 15–20 minutes longer, until browned and crisp. (This is a good time to add your tortillas to the oven, bake wrapped in foil for 15 minutes.)
Meanwhile, make the lime crema. Place ¾ cup sour cream, 2 tbsp mayonnaise , ½ cup cilantro , lime juice and zest, 1 clove garlic, ½ tbsp red wine vinegar, ¼ cup pepitas, and ¼ cup cotija cheese in a blender or food processor and blend until smooth.
Enjoy the roasted cauliflower in tortillas with your favorite toppings.
Notes
Storing
Store any leftover roasted cauliflower in an airtight container in the fridge for 1-2 days, ready to be served as a vegetable side dish, added to this Easy Power Bowl Recipe, or blended to make mashed cauliflower.
Store the cilantro crema sauce in a sealed jar or squeeze bottle for up to 5 days in the fridge. The texture of the crema will naturally thicken as it sits in the fridge. If it’s too thick, stir in a little lime juice or a splash of water until it thins out.
Tips and tricks
You can make the crema ahead of time and store it in the fridge, covered with plastic wrap, for up to 3-4 days. The flavors will meld together and intensify for an even better taste!
Cut the cauliflower into uniform pieces so that they roast evenly and at the same rate. Make sure to also flip them midway to ensure that they roast on all sides.
If you don’t like cilantro in your crema, you can try one of these substitutes.
Warm the tortillas in the oven during the last 15 minutes of roasting the cauliflower so that you aren’t left waiting any longer to assemble and enjoy these veggie tacos! Make sure to wrap the tortillas in foil to prevent them from drying out.
