Ingredients and substitutions

- Vegetables - I used zucchini, yellow squash, red bell pepper, and onion. Other great roasting vegetables include brussels sprouts, broccoli, and cauliflower. Remember the more dense your vegetable, the smaller you'll want to slice it to keep the same cook time.
- Olive oil - Any neutral cooking oil works in this recipe.
- Seasoning - Chili powder, cumin, coriander, garlic powder, oregano, and salt add a complex, savory, and slightly spicy flavor to your veggies.
- Fresh cilantro - I like to sprinkle some fresh chopped cilantro on top of my roasted veggies just before serving. If you don't like cilantro, it can be substituted with parsley or omitted entirely.
How to make Mexican roasted vegetables

- Add sliced veggies to a bowl and top with oil and seasoning.
- Toss until evenly coated.
- Spread onto a greased or lined baking sheet and spread into a single layer.
- Roast until fork tender and lightly browned.
Tips and tricks
Pat veggies dry - After slicing your zucchini and yellow squash, they'll begin to 'sweat' as they sit. Pat your squash dry with a paper towel just before tossing in the olive oil and spices.
Don't overcook - Take care not to overcook your squash in the oven. Zucchini cooks fairly quickly in the oven, needing only 16-18 minutes at most to cook through (when thick sliced).
Use thick slices - Slice your zucchini and yellow squash into thick, ½ inch circles. Thin zucchini cooks faster and can get mushy when overcooked.
Slice hearty veggies smaller - Slice heartier vegetables like bell pepper, broccoli, or brussels sprouts into smaller pieces. These vegetables take longer to cook, so slicing them smaller gives them similar cook time when paired with squash.

Zucchini and yellow squash have a very high water content - they're about 90 to 95% water. To prevent them from getting soggy, make sure you're not overcooking them, pat them dry before seasoning, and don't slice them too thin. Thin veggies cook faster and get mushy faster.
