How to make Mexican Roasted Vegetables

Top tips

  • Be sure to coat the vegetables well with the spices before roasting. This helps to ensure that everything is super flavorful after cooking.
  • Cut the zucchini and squash a little thicker so that they retain a good texture when roasting. If you cut them too thin, they can get mushy.
  • Use an extra large baking sheet to ensure that the veggies have room to spread out so they can get air flow around them in the oven. This helps to ensure that everything cooks evenly and is done at the same time. I use these large stainless steel pans, they are easy to clean and never rust!
  • To double this recipe, you will need two large sheet pans. Half way through cooking, rotate the pans to ensure they get evenly cooked.
  • If you are short on time – prep the veggies in advance. You can cut the onions, pepper and squash up to 3 days in advance. Simply store the cut veggies in an airtight bag or container in the fridge until you are ready to prep.
  • This recipe is not spicy. If you want to add some spice, add about 1/2 teaspoon of crushed red pepper flakes, cayenne pepper or add some fresh or pickled jalapeno.

Other additions

  • Veggies: Poblano peppers, mushrooms, jalapeno peppers, finely chopped broccoli, cauliflower rice

Common questions

How to use leftover Mexican vegetables

  • Reheat and add to tacos, burritos or breakfast burritos
  • Add to frittatas or egg bakes
  • Make a quick side dish for your morning eggs by scrambling up these veggies with some hash brown potatoes

Can you make this with frozen vegetables

Yes, you can make Mexican roasted vegetables with frozen veggies. I would suggest using frozen bell peppers, frozen onion, cauliflower rice and frozen broccoli (that is finely chopped). I don’t recommend using frozen zucchini or squash as it can get waterlogged and soggy when roasted.

Be sure to add 5-10 minutes to the cooking time to ensure that excess water from the veggies defrosting in the oven has time to evaporate.

Can you use taco seasoning?

Yes, if you want to make this recipe even easier to prepare, you can simply toss the veggies in about 1.5 tablespoons of taco seasoning instead of measuring out the spices.

Storing leftovers

  • Fridge: Store leftover roasted Mexican vegetables in the fridge for up to 4 days.
  • Reheating leftovers: cook in the microwave 1:30 – 2 minutes or reheat in a skillet over medium heat for 5-7 minutes until heated through.
  • Freezer: I don’t recommend freezing leftovers since the cooked zucchini and summer squash get watery when frozen and defrosted.
