🥣 How to make (step-by-step photos)

1️⃣ Step One: Preheat oven + prep veggies

The first step is to preheat your oven to 400 degrees F (200 C). Next, give the veggies a good wash to remove any dirt and then cut them for roasting.

  1. To cut zucchini: Slice the ends off, then cut into 1/2 inch (1 centimeter) slices.
  2. To cut sweet potatoes: Cut off the ends, then cut potatoes into small 1/2 inch cubes for roasting (you do not need to peel them before roasting).

2️⃣ Step Two: Season zucchini + sweet potatoes

Mix the zucchini and sweet potatoes together on a baking sheet. Combine with a small amount of olive oil until they're completely coated.

Add sliced garlic, salt, pepper, and any other dried or fresh herbs that you'd like to the veggie mixture.

3️⃣ Step Three: Roast vegetables in the oven

Bake zucchini and sweet potatoes until tender and brown around the edges. This will take about 25 minutes, give or take, depending on your oven.

About 10-15 minutes into cooking, toss the vegetables so they brown on all sides.

When done cooking, take vegetables out of the oven. Enjoy immediately as a side dish, or let them cool and mix into salads and other dishes.

❓ Recipe questions + quick tips

How do you make zucchini not soggy?

Zucchini has a higher water content, which can make it soggy. You can prevent it from becoming soggy by drying it well after slicing, and seasoning it with salt before roasting. Salt helps draw water out of the vegetable and cooking it at a high heat will evaporate more water. Additionally, thicker slices of zucchini are less likely to become soggy.

What do sweet potatoes pair well with?

The naturally sweet flavor of sweet potatoes contrasts well with just about any food. You can roast them along with other veggies like broccoli, Brussels sprouts, zucchini, carrots, or cauliflower. Sweet potatoes taste great when mixed with sweet and savory spices, including cinnamon, garlic, thyme, cilantro, chili powder, rosemary, and more. You can also eat them as a side dish along with a plant-based protein.

Do you peel zucchini before you cook it?

You do not need to peel zucchini before cooking it. Zucchini skins contain lots of nutrients, including fiber and carotenoids, which have a variety of health benefits. Leaving the skins on zucchini can also keep it from getting soggy!

Should I parboil my sweet potatoes before roasting?

It's not necessary to parboil sweet potatoes before roasting. When baked, they become tender and crispy enough, and cook through fairly quickly so there's no need for boiling.


🌿 Herb + spice combination ideas

We love how versatile this recipe is! Roasted zucchini and sweet potatoes taste delicious with just about any seasoning combination. Here are some ideas:

  • Chili powder, paprika, salt, and pepper. Add a spicy kick to the veggies by roasting along with chili powder, paprika, and a sprinkle of salt and pepper.
  • Rosemary and Italian seasoning: Sprinkle a little rosemary and Italian seasoning over the veggies for a delicious savory flavor.
  • Minced garlic and chopped onion: Roast zucchini and sweet potatoes with minced garlic and onions for a flavor boost.
  • Homemade breadcrumbs and nutritional yeast: Bake vegetables in the oven until browned, then sprinkle with breadcrumbs and nutritional yeast (parmesan cheese would work, too!), then roast again for a few minutes until breadcrumbs turn golden.

🧊 How to store

You can use leftover roasted vegetables in so many ways, but it's important to store them correctly! Keep their flavor with these storage tips:

Refrigerator storage: Store vegetables in an airtight container in the refrigerator for up to 3-4 days.

Freezer storage: For the best taste and texture, we don't recommend freezing roasted vegetables as they will lose their texture when thawed.


♻️ Sustainable kitchen tips

Looking for ways to be more eco-friendly in the kitchen? We've got you covered! Here are some tips to make the most out of your ingredients.

Take advantage of zucchini and sweet potato season. We suggest making this recipe when sweet potatoes and zucchini are at the height of their growing season! Sweet potato season starts in late summer in California, and zucchini is in season spring through fall. Find out when they're in season in your area here.

Compost sweet potato sprouts. Sprouts don't belong in the garbage! Toss them in your compost pile – your soil (and the planet) will thank you later.

Re-purpose the veggie scraps. Any scraps you have from cutting the vegetables, like zucchini ends and sweet potato peels, can be added to a food scrap stock. This is great to keep on hand for soup and to use as a cooking liquid. If you're not able to keep the scraps, make sure to place them in your compost bin.
