Ingredient Notes & Substitutions

The following is an overview of the ingredients you’ll need to make this recipe, as well as recommended substitutions. For the exact measurements, be sure to refer to the recipe card below.

  • Zucchini: instead of zucchini, you can also use summer squash.
  • Sweet Potato: the longer sweet potatoes (as shown on the image above) are ideal, but any shape will do! Instead of sweet potatoes, you can also use regular potatoes or more zucchini.
  • Olive Oil: the oil helps add a little crisp!
  • Fresh Thyme: fresh thyme goes with the zucchini & sweet potatoes perfectly. Rosemary would be a great alternative if you don’t have (or don’t like) thyme.
  • Garlic: I believe that more is more when it comes to garlic, but I know not everyone agrees, so feel free to either omit or increase the amount to taste!
  • Sea Salt & Black Pepper: the seasonings are intentionally kept super simple to allow the flavors of the vegetables to shine through. That said, obviously fee free to adjust to your liking. You could add chili flakes, cumin, or a pinch of coriander for a little extra pep, for example.

The Benefits of Zucchini & Sweet Potatoes

  • Zucchini: zucchini may help reduce blood sugar levels, are high in antioxidants, and can aid digestion.
  • Sweet Potatoes: sweet potatoes are high in dietary fiber, very nutritious, great for gut health, and thanks to their beta carotene, they also support healthy vision alongside other health benefits.

How to Make These Roasted Zucchini & Sweet Potatoes (Step by Step)

The following is a step-by-step overview of how to make this recipe. For a recap, be sure to check out the recipe card below.

Preheat the oven to 428ºF/220ºC using your oven’s conventional setting. If using a convection/fan forced setting, set the temperature to 200ºC/400ºF.

Serving Suggestion

This roasted zucchini & sweet potato side dish goes well with savory holiday dishes, as well as other sides like these umami roasted potatoes or this chickpea salad.

If you’re including this recipe in your weekly batch meal prep, here are some ideas on how to combine it with other dishes:

  • Noodle Salad: simply mix the roasted zucchini & sweet potatoes with cooked noodles (use chickpea or lentil pasta for added protein) and enjoy either cold or warm.
  • Macro Bowl: combined with other ingredients like cooked quinoa, sautéd spinach or kale, cooked beans or lentils, as well as a delicious dressing, these roasted veggies complete a delicious and nourishing macro bowl.
  • Dense Bean Salad: simply mix the veggies into a bean salad with some fresh chopped tomatoes, onions, and cucumber, as well as some lemon juice (and jalapeños for added spiciness).
  • Sandwich: these veggies would go well with a sandwich with baked tofu!

Recipe Tips & Storage

  • Texture: Following this recipe will make the vegetables’ texture tender and flavorful. If you want a slightly crispier result, I’d recommend patting the zucchini with paper towels or a kitchen towel to remove extra moisture and roasting the vegetables for an extra 5-10 minutes. Using the oven’s convection/fan setting will also help.
  • Storage & Meal Prep: If you’re making this recipe as part of a batch meal prep session, let the roasted vegetables cool, then transfer them to an airtight container and store them in the fridge for up to 3-4 days. You can then either reheat the roasted zucchini & sweet potatoes when serving or enjoy them cold mixed into a noodle salad or other dish.
