🎙 What people say about this recipe
"I've roasted sweet potatoes many times but this recipe is by far the best tasting I ever had. I couldn't stop eating them. And my dog loved them too! I will make them this way every time from now on."
- Steve A.
🧄 Very useful ingredient notes
- Sweet potatoes - Look for sweet potatoes that are firm, without a lot of blemishes or indentions on the surface (these indicate the sweet potato may be old or bruised and going bad).
- Chili powder - a blend of spices used to make Texas Chili and other TexMex-inspired recipes. Not to be confused with chile powder (with an "e"). Chile powder is typically one type of chile pepper, dried and ground.
- Ground cumin - Cumin seeds ground into a powder is a key aromatic and warm spice in TexMex cuisine.
📋 Substitutions and variations
Here are some suitable substitutions for the ingredients in this recipe:
- Sweet potatoes - instead of sweet potatoes, you can use butternut squash or summer squash (these may roast faster, so watch them) or even white or yellow potatoes
- Chili powder - instead of chili powder, you can use taco seasoning (reduce the salt if using this, since taco seasoning is already salted), smoked paprika or sweet paprika. You can also use ancho chile powder, chipotle pepper powder or other chile pepper powder you have, but may want to reduce the quantity since these will produce a spicier result since they are 100% hot chiles.
- Dried parsley or cilantro - use finely chopped fresh parsley or cilantro instead and use ¼ cup instead.
Switch things up with these variation ideas!
- Spicy - add cayenne pepper or red pepper flakes to increase the spice level
- Russets - Make this other recipe on my site using russet potatoes and onions with the same seasonings of cumin, garlic and chili powder.
- Italian-inspired - make these to go with an Italian meal by using an Italian blend of herbs (basil, oregano, marjoram, rosemary, parsley) and garlic
- Greek-inspired - make these to go with a Greek meal by using Greek oregano, onion powder, garlic powder and finishing them with a drizzle of red wine vinegar or lemon juice
🔪 Instructions
Step by step instructions for how to make roasted sweet potato cubes without using oil in the oven.
- Pre-heat the oven to 400°F. Line a baking tray with parchment paper or a silicone baking mat. Add diced sweet potatoes to a medium bowl, along with the chili powder, ground cumin, granulated garlic, salt and dried cilantro/parsley. Toss to coat the sweet potatoes in the spice mixture. Spread the sweet potato on the lined baking tray in a single layer. Use two trays if they don't all fit in a single layer on one tray.
- Bake for 25-30 minutes, until fork tender. Remove from oven and add to tacos, tostadas, nachos, burrito bowls or salads.
🥡 Make ahead and storage tips
These TexMex sweet potatoes can be made ahead or meal-prepped and then stored in the refrigerator for up to 5 days. They can also be frozen in an airtight bag or container for up to 3 months.
👨👩👦👦 Serving suggestions

❓ FAQ
When roasting cut sweet potatoes in the oven, line the sheet pan with parchment paper or a silicone baking mat to prevent them from sticking to the pan. This is an easy way to prevent stuck-on sweet potato without having to use oil. (It also reduces clean up time!)
