How To Make This Recipe: 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.
Keep a close eye on them so they don't burn.
Frequently Asked Questions
Yes!
You can make this recipe with either sweet potatoes or regular white potatoes following the same recipe.
Yes!
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".
The amount used in the entire recipe is ½ teaspoon and it yields approximately (4) servings, so the amount per serving is less than ⅛ teaspoon and is minimal.
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.
The only ingredient in this recipe that is not Medical Medium® Compliant is the nutritional yeast, which can be omitted.
My favorite healthy, vegan dip to pair with this recipe is my cool and tangy Lemon Dill Avocado Dressing (shown in the photos).
It's made with only 6 clean, real food ingredients and can be ready in about 5 minutes!
Karielyn's Expert Tips + Ingredient Substitutions
Seasonings. The secret to making these oven-baked fries flavorful 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.

David Walker says
Great recipe. I use fresh turmeric daily and Do so because “it is good for me” but in this recipe it is delicious. I didn’t have any dried hot pepper but I served them with Cholula . Delicious! Thank you.

Karielyn Tillman says
Hi there David! I'm so glad to hear that you enjoyed the recipe! I, too, don't particularly love the taste of turmeric but use it because "it's good for me" - just like you said!
Thank you for trying out the recipe and for taking the time to let me know you liked it...I sincerely appreciate it! 🙂
Nancy says
I’m going to try this in air fryer. Can I use olive oil instead of avocado oil? Finally, is that just avocado/guacamole dip in pic? Thank you!
Karielyn says
Hi Nancy! In this recipe, you can definitely substitute olive oil for avocado oil. It is just my personal preference to use avocado oil when I bake, roast or saute' anything at high heat.
I'd love to know how the fries turn out in the air-fryer too!
Yes, the dip in the photo is an avocado-based recipe from here: https://thehealthyfamilyandhome.com/lectin-free-vegan-lemon-dill-avocado-dressing/, but a regular guacamole recipe would be good too.
Thanks for your question and I hope you enjoy the recipe 🙂
Abbe says
Just a note, cayenne pepper is a lectin (nightshade). Made without and very yummy!
Karielyn says
Hi there Abbe! Actually, cayenne pepper is lectin-approved - per Dr. Gundry 🙂
I am going to add a screenshot to my post 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 as you did 🙂
Thanks the feedback and for trying out the recipe...glad to hear you enjoyed it! 🙂
