🥣 How to roast sweet potatoes and asparagus together (step-by-step photos)

1️⃣ Step One: Preheat oven + prepare veggies

Start by preheating your oven to 400 degrees F (200 C). Give the sweet potatoes and asparagus a quick wash to remove any dirt, then cut them for roasting.

  1. To cut asparagus: Trim the tough ends off of the asparagus, then cut into small 1 inch pieces. You can also leave them in longer pieces if you'd like (we left them long in the photos), but making them smaller makes it easier to eat them with sweet potatoes.
  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).

Pro tip! Make the sweet potatoes and asparagus easier to eat by cutting them into similar sized pieces. If they're the same size, they will have similar cooking times and add extra crunch.

2️⃣ Step Two: Arrange veggies on a sheet pan

Place the cut sweet potatoes and asparagus on a baking sheet. To make sure they cook evenly, spread them out evenly on the pan.

Tip! We like to keep the vegetables separated on the roasting pan. Sweet potatoes can take longer to bake and you can easily scoop the asparagus off the pan when it's done and keep cooking the potatoes.

Cover the veggies with a small amount of olive oil and mix until they are completely coated. Season with sliced garlic, as well as salt and pepper to taste.

3️⃣ Step Three: Bake vegetables until golden brown

The last step is to roast the veggies in the oven. You'll cook them until they're tender and brown around the edges. Depending on your oven, this will take about 35 minutes.

To make sure the sweet potatoes and asparagus cook evenly, give them a toss halfway into cooking. If the asparagus is cooking faster than the sweet potatoes, remove it to a plate and continue to cook the potatoes until they're done.

Take the veggies out of the oven when they are finished. You can serve immediately if using as a side dish. If serving on top of salads and bowls, let the veggies cool to room temperature before using.

❓ Recipe questions + quick tips

What goes well with sweet potatoes?

Sweet potatoes can be enjoyed alongside just about any other vegetable. They taste great with broccoli, brussels sprouts, zucchini, green beans, bell peppers, and asparagus. They can be served with meat, fish, or plant-based proteins like beans, lentils, and tofu. You can enjoy them in soups, salads, and other mixed dishes. Sweet and savory flavorings, from cinnamon, to garlic, onion, and rosemary taste great with sweet potatoes.

Why is my roasted asparagus mushy?

Moist heat cooking methods, like steaming and boiling, can make asparagus mushy. Roasting it typically solves this problem, but it can become mushy if you add too much oil. Make sure to drizzle just a small amount of olive oil over the asparagus before you roast it, and the end product should come out crispy and delicious (not mushy!).

Do you cut asparagus before roasting?

Before roasting, you should cut the ends off asparagus. The ends are difficult to eat, and can cause the asparagus to become stringy when roasted. You can cut just the ends off and roast long pieces of asparagus, or cut the asparagus into smaller pieces.

Is roasted sweet potato healthy?

Roasted sweet potatoes are healthy. They are high in fiber and antioxidants, which have a variety of health benefits. Additionally, sweet potatoes are a source of vitamin A, vitamin C, potassium, and many other nutrients. More information about the nutrition content of sweet potatoes can be found here.
