How To Make Spicy Oven-Baked Sweet Potato Fries: Step-by-Step Instructions

This is an easy plant-based snack recipe that takes less than 10 minutes to prepare and I'll show you how with step-by-step instructions below.

Preheat the oven to 425 degrees. Prepare a cookie sheet lined with parchment paper and set aside.

Step 1: Prepare the Sweet Potato

First, peel the sweet potato and then cut the ends off.

Cut the sweet potato in half from the top to bottom so the fries will be the perfect length.

Next, cut the sweet potato into long, thin "french fry" pieces.

If you use a large sweet potato, you should get about 50-60 fries.

Transfer the cut sweet potato fries to a large mixing bowl.

Step 2: Add the Avocado Oil

Second, add the avocado oil and toss the sweet potato fries until they are evenly coated.

Step 3: Add the Seasonings

Third, add the seasonings to the sweet potato fries, but add one seasoning at a time, and add the nutritional yeast last.

Toss the sweet potatoes after adding each seasoning to make sure the seasoning is evenly distributed.

Step 4: Bake the Sweet Potato Fries

Lastly, transfer the seasoned sweet potato fries to the prepared cookie sheet and bake at 425 degrees for approximately 15-20 minutes.

Remove the cookie sheet from the oven, toss the fries and return to the oven to bake for an additional 5-10 minutes more.

Expert Tips + Ingredient Substitutions for Spicy Oven-Baked Sweet Potato Fries

Seasonings. The secret to making these oven-baked fries crispy is in the order of adding the seasonings.

Toss the sweet potato fries in avocado oil
Add each seasoning one at a time and toss in between
After that, add the nutritional yeast last

And don't forget, you can always adjust the amount of seasonings to your preference!

Cayenne Pepper. There seems to be confusion as to whether cayenne pepper is a lectin-free approved ingredient. After carefully researching this, I found a source, directly from Dr. Gundry himself, stating "cayenne is fine". Please see the screenshot below*.

Nutritional Yeast. You will need to omit this ingredient if you need the recipe to be 100% Medical Medium compliant.

Avocado Oil. I always use avocado oil whenever I bake something in the oven at high heat. However, you can substitute this with organic extra-virgin olive oil.

Himalayan Pink Salt. This is my salt of preference, but you can always substitute with sea salt.

*Note:I'm adding a screenshot from Dr. Gundry’s Twitter page where he gives cayenne pepper the “ok” as a lectin-approved ingredient, which is why I included it in my recipe and classified the recipe as “Lectin-Free”. However, a person who needs to avoid nightshades in general, for reasons other than lectin-related, would need to just omit the cayenne pepper from the recipe.

Recipe Notes

*Nutritional Yeast: You will need to omit this ingredient if you need the recipe to be 100% Medical Medium compliant.

**Cayenne Pepper: There is some confusion as to whether cayenne pepper is a lectin-free ingredient. However, I have attached a screen-shot in the body of the post with a quote from Dr. Gundy saying it is lectin-free approved. If you need to avoid nightshades in general, for reasons other than lectin-related, just omit the cayenne pepper from the recipe.

Avocado Oil: I always use avocado oil when baking something in the oven at high heat, but you can substitute with organic extra-virgin olive oil if you prefer.

Himalayan Pink Salt: This is my salt of preference but it can always be substituted with sea salt.

Serving Size: If you use a large sweet potato, the recipe makes approximately 50-60 fries, or 4 servings at approximately 12 fries each.
