This Roasted Cauliflower recipe takes a simple veggie and jazzes it up with Tex-Mex spices and pepitas. Roasting it simply in the oven, until it’s tender and caramelized, makes this dish utter perfection!

Cauliflower can be a bit bland on its own, I think everyone can agree. But when you roast it with the simplest combination of butter, olive oil, salt, and pepper…it’s magically transformed into something so tasty you almost forget it’s a vegetable. I added in some special-yet-still-simple seasonings with this recipe, and pepitas (pumpkin seeds) too — and this is, oh my, one delicious platter of cauliflower! (If you like pickles, be sure to check out my Pickled Cauliflower – so irresistibly yummy!)
“Cauliflower is such an unsung hero — we love it. With the addition of the ancho chili powder, pepitas and of course the cilantro — this dish is absolutely delicious. Definitely will be a repeat at our house.”

What You’ll Need
Here’s the list of ingredients for this Mexican roasted cauliflower. Scroll down to the printable recipe card to find the exact ingredient quantities and full recipe instructions.
- Cauliflower – Use cauliflower that’s obviously fresh-looking. Cut it into florets.
- Olive oil – This makes the cauliflower crispy and golden.
- Spices – Cumin, ground ancho chili, flaky sea salt, and freshly ground black pepper.
- Lime – You’ll need both the zest and the juice.
- Butter – Unsalted butter adds a little more richness to the usual roasted cauliflower equation.
- Garlic – Slicing it rather than mincing it helps keep it from burning to a blackened crisp, plus this adds more random, noticeable bites of garlic…which is FUN!
- Pepitas (pumpkin seeds) – For nutty flavor and a satisfying crunch. Pepitas are a staple of traditional Mexican cuisine
- Cilantro – Adds freshness and a pop of color.
How to Make Mexican Roasted Cauliflower With Pepitas
This recipe is super easy! Here’s what you’ll need to do.


- Prepare. Place a sheet pan in the oven. Preheat oven to 450ºF.
- Oil the cauliflower. Fold the florets with half the olive oil, then add the remaining oil and fold to coat again.
- Season. Combine the seasonings and lime zest in a small bowl, and then add half of this mixture to the cauliflower; fold to combine. Then add the rest of the mixture and fold again.


- Roast. Spread the seasoned cauliflower on the hot sheet pan and roast for 15 minutes without stirring.
- Add garlic and pepitas. Combine the melted butter and garlic slices, then add this mixture, along with the pepitas, to the cauliflower. Toss to combine and roast 5 minutes more.

- Finish. Squeeze lime juice over the top, sprinkle with cilantro, and serve hot.
Brenda’s Tips + a Few Variations
Here are a few more notes on this roasted cauliflower recipe:
- Don’t skip preheating the pan. When you add the oiled cauliflower to a pan that’s already hot, this jump-starts a nice sear, making it beautifully browned and crisp.
- Dry the cauliflower well. If it’s still wet, your cauliflower will steam in the oven rather than roast. While the flavor will still be nearly the same, you will miss out on the gorgeous, delicious caramelization and it will be more soggy than crisped.
- Aim for same-size. Cut the florets roughly the same size so they roast at the same rate.
- Give the cauliflower some space. Spread the florets out on the pan as much as possible, to allow for air circulation. Otherwise, if they’re all bunched up together, they will only steam.
- Swap out the ancho for chipotle. For more heat, use chipotle powder instead of ancho. Chipotle is much more potent/spicy, so I’d recommend that you start with only half the amount and then give it a taste-test.
- Add some cheese. Finish with crumbled cotija cheese for a salty little pop of flavor. Our family loves this variation!

Serving Suggestions
I often serve Mexican roasted cauliflower alongside tacos; it’s the perfect veggie side. Try my Fish Tacos Recipe, Blackened Shrimp Tacos, or Mole Pork Tacos.
Of course, it also works well with other Tex-Mex dishes like Cilantro Lime Rice and Taco Stuffed Sweet Potatoes.
Storage and Reheating
- Refrigerator: Store any leftovers in an airtight container in the refrigerator for up to 4 days. (You could freeze it if you’d like, but the flavor and texture won’t be as good the second time around.)
- To reheat: Reheat in a 425ºF oven or air fryer, eat straight out of the fridge (it’s awesome in salads!), or gently microwave.

Roasted Cauliflower with Pepitas
Ingredients
- 1 large head cauliflower, cut into smaller florets, and florets cut in half
- 3 tablespoons olive oil
- 2 teaspoons ground cumin
- ½ teaspoon ground ancho chili
- 1 teaspoon flaky sea salt
- ¼ teaspoon freshly ground black pepper
- 1 large lime, divided into zest and juice

- In a small bowl, combine cumin, ancho chili, sea salt, black pepper. Stir in zest from the one lime. Sprinkle half the spice mixture over the cauliflower, and fold to combine. Then sprinkle remaining spice mixture over the cauliflower, and fold again to combine.
- Remove hot pan from oven and add seasoned cauliflower, spreading it out evenly across the pan. Place pan back into the oven and roast for 15 minutes without stirring, letting the edges of the cauliflower caramelize.
- In a small bowl or cup, combine melted butter and garlic slices. Remove hot pan of cauliflower from the oven and add buttery garlic slices and the pepitas to the cauliflower. Toss to evenly combine, then place pan back into the oven to roast for an additional 5 minutes, or until cauliflower is nicely caramelized.
- Remove pan from oven. Sprinkle with a bit more sea salt and black pepper, if desired. Serve straight from pan, if you like – or transfer cauliflower to a serving platter. Cut the zested lime in half and squeeze the juice over the top of the cauliflower. Sprinkle with chopped cilantro to finish. Serve hot, with additional fresh lime wedges to squeeze over individual portions.
