Making this roasted cauliflower taco recipe is a breeze, and the result is a deliciously satisfying meal. Follow these simple steps to create your own taco feast.

Preparing the Vegetables and Oven

Begin by heating your oven to 400°F (200°C) and lining a baking sheet with parchment paper or aluminum foil for easy cleanup. Next, chop the cauliflower into small, even florets for quick roasting. Thinly slice the red onion and bell pepper, and mince the garlic cloves. This ensures that everything cooks evenly and gets that perfect blend of flavors and textures.

Seasoning the Mix

In a large bowl, combine the cauliflower florets, bell pepper, onion, garlic, smoked paprika, dried oregano, ground cumin, sea salt, and a drizzle of neutral oil (like light olive oil). Toss everything together until the veggies are well-coated with the oil and seasonings.

Roasting to Perfection

Spread the seasoned vegetables on the prepared baking sheet in an even layer. Place in the oven and roast for about 15-17 minutes. You’re aiming for the cauliflower to be tender and lightly golden brown, with a bit of a crispy edge for that perfect texture.

Preparing the Cabbage Slaw

While the veggies are roasting, prepare the slaw. Thinly slice the red cabbage and jalapeno (removing seeds for less heat if desired), and chop the cilantro. Toss these with lime juice in a medium bowl, adjusting the lime to taste.

Assembling the Tacos

Heat a large pan or griddle over medium-low heat. Lightly oil the pan and warm the tortillas for about a minute on each side, or until they’re just a bit crispy and golden.

Recipe Notes and Expert Tips

To get the most out of your roasted cauliflower tacos, keep these tips in mind:

  • Make it Spicier: For extra heat, increase the amount of jalapeños in the slaw, add a diced chili or chili powder to the vegetable mix before roasting, or serve with a spicy hot sauce.
  • Freshness Counts: Use fresh lime juice for the slaw for the best flavor. It really makes a difference!
  • Can I use frozen cauliflower for this recipe? Yes, you can use frozen cauliflower. Just make sure to thaw it completely and pat it dry to remove excess moisture before seasoning and roasting.
  • Customize Your Toppings: Feel free to add other toppings like avocado slices, vegan sour cream, or a sprinkle of fresh cilantro to personalize your tacos.
  • For Extra Crispiness: If you love your veggies extra crispy, broil them for the last 2-3 minutes of roasting. Just keep a close eye to prevent burning.
  • Use Parchment Paper: Lining your baking sheet with parchment paper not only helps with cleanup but also prevents sticking without the need for too much oil.
  • Heat Your Tortillas: Warming the tortillas before assembling the tacos makes them more pliable and enhances their flavor.
  • Can I make the slaw without cilantro? Yes, if you’re not a fan of cilantro, you can simply omit it from the slaw or substitute it with parsley for a different but still delicious flavor profile.
  • Are these tacos suitable for a keto diet? While cauliflower is keto-friendly, corn tortillas are not. Substitute the corn tortillas with a keto-friendly option like low-carb tortillas, cheese tortillas, or lettuce wraps.
  • Leftover Ideas: If you have leftover cauliflower mix, it’s great in a salad, as a side dish, or for meal prep for the next day.

How to Store Leftover Roasted Cauliflower Tacos

Leftovers? Great! Here’s how to keep your tacos fresh and tasty:

  • Cauliflower: Keep the roasted cauliflower and vegetable mix in an airtight container in the refrigerator. It should stay good for up to 3 days.
  • Cabbage Slaw: The slaw can also be refrigerated in a separate airtight container. For the best texture, consume within 2 days.
  • Reviving Tortillas: If you have leftover tortillas, store them in a zip-lock bag at room temperature. They’ll stay fresh for a few days. Reheat on a pan for a minute on each side to bring back their warmth and flexibility.
  • Reheating the Mix: When you’re ready to enjoy your tacos again, reheat the cauliflower mix in the oven at 350°F (175°C) for about 10 minutes or until heated through. This helps to maintain its delicious roasted texture.

What to Serve with Roasted Cauliflower Tacos

Pairing your roasted cauliflower tacos with the right sides and accompaniments can turn a simple meal into a feast. Here are some delicious ideas:

Avocado Crema

A smooth and creamy avocado sauce can add a rich, velvety layer to your tacos. Simply blend ripe avocado with lime juice, garlic, and a touch of salt until smooth. This sauce brings a cool, refreshing contrast to the spicy and savory flavors of the tacos. Guacamole with chips is also a great idea!

Quick Pickled Red Onions

Quick pickled red onions add a bright, tangy crunch that complements the roasted vegetables beautifully. Thinly slice red onions and marinate them in a mixture of apple cider vinegar, water, sugar, and salt for at least an hour. The vibrant pink hue they turn is as appealing to the eye as it is to the palate.

Cilantro Lime Rice

For those looking for a more filling meal, cilantro lime rice is a perfect side. Its fresh, citrusy flavor balances the rich spices of the tacos, and it’s a great way to turn your taco night into a substantial dinner.
