When it comes to roasted sweet potatoes, my favorite way to add extra flavor is by adding plenty of spices and homemade sauces! They can take any simple side dish to the next level.

These roasted potatoes and sweet potatoes have a hint of thyme and oregano. The vegan pesto sauce poured on top adds so much brightness and complements the flavors perfectly!

By pairing sweet potatoes with potatoes, you get a pop of sweetness that works so great with the basil pesto sauce. You can also add any other root vegetables to this recipe, like carrots and onions.

Yield: 4 servings

Prep time: 10 min

Cooking time: 40 min

Total time: 50 min


1 sweet potato

3 small red potatoes

A drizzle of olive oil

¼ tsp salt

½ tsp oregano

½ tsp thyme

Garnish: green onions

Pesto sauce:

2 cups basil leaves

3 cloves of garlic

1 lime

¼ tsp salt

4 tbsp olive oil

4 tbsp water


  1. Preheat the oven to 400 F.

  2. Chop the potatoes and sweet potatoes into small pieces.

  3. To a baking dish, add the potatoes and sweet potatoes, a drizzle of olive oil, salt, oregano, and thyme. Cook in the oven for 40 min.

  4. While that’s cooking, let’s make the pesto sauce! To a blender, add the basil, garlic, lime juice, salt, olive oil, and water. Blend until smooth and set aside.

  5. Pour the pesto sauce on top of the roasted potatoes and sweet potatoes and garnish with green onions. The perfect side dish for any meal!


  • Store in airtight containers for about a week. You can freeze the pesto sauce for 3-4 weeks.

  • The pesto sauce yields ¾ cup. You can add ¼ cup of pine nuts for a creamier version.

  • I like this sauce bright and acidic, but if you prefer it less tart, use only the juice of half a lime.

*Potatoes: Carbs are the main dietary component of potatoes. Those cooled down after boiling may provide some resistant starch, which can improve gut health. Potatoes also contain small amounts of high-quality protein. They are a good source of several vitamins and minerals, including potassium, folate, and vitamins C and B6.

*Sweet potatoes are mainly composed of carbs and fiber and relatively low in protein. They're an excellent source of beta carotene, vitamin C, and potassium. Sweet potatoes are also likely healthier than regular potatoes, they have a lower GI, more fiber, and large amounts of beta carotene. Also, they may have a variety of benefits, including improved blood sugar regulation and reduced oxidative damage.

*Basil: Because basil is generally used in small quantities, the only substantial nutrient it provides is vitamin K. Basil also supplies plant compounds, which contribute aroma, flavor, and health benefits. Both sweet and holy basil have a long history of medicinal use. A few studies in people suggest benefits for blood sugar and stress, though more research is necessary.
