Guide to Roasting Asparagus in a Toaster Oven

Asparagus in a Toaster Oven

Vegetables are one of the simplest and most delicious foods to make in a toaster oven. Asparagus in particular tastes great when roasted or baked. 

How to Roast Asparagus Spears in a Toaster Oven?

Follow these simple steps to make tasty roasted asparagus!

First, preheat your toaster oven to 425 degrees Fahrenheit. While the toaster oven is getting hot, prepare the asparagus.

You’ll want to start with fresh asparagus. If you can find some that were just picked, the taste will be that much better!

Thoroughly wash and dry the asparagus to remove any dirt or pesticides. If the asparagus is very thick, you’ll want to peel it to remove the tough skin. Thinner spears of asparagus do not need to be peeled.

Cut off about an inch from the bottom of each spear. These parts are quite tough and chewy, so they’re best discarded.

Choose a baking sheet and lightly coat it with oil. Too much oil will start to smoke in the toaster oven. You just want enough so that the asparagus doesn’t stick to the baking sheet. Olive oil or canola oil work great.

Spread your asparagus spears in a single layer on the baking sheet. This ensures that they all cook evenly. Drizzle a little oil on top of the asparagus.

Sprinkle generously with salt and pepper. You can also choose to season with lemon pepper, dill, or garlic.

Once the toaster oven is preheated, place the tray of asparagus inside. Let cook for 10 minutes, then turn the asparagus or gently shake the pan to rotate the spears. Cook for another 5 minutes, or until tips are lightly browned and spears are tender.

Telling When The Asparagus is Done

The easiest way to tell when your asparagus is done cooking is to pierce the spears with a fork. They should be tender enough that the fork goes through easily.

You can also look at the tips of the asparagus to see if they’re finished cooking. Asparagus tips should be lightly browned when done.

Thicker spears of asparagus will take a bit longer to cook than thinner spears. It’s best to choose spears that are relatively similar in size so that they are all cooked evenly.

Best Temperature for Preparing Asparagus in a Toaster Oven

There are three options for cooking asparagus in your toaster oven: roasting, baking, and broiling. All three methods use different temperatures. 


When roasting asparagus in the toaster oven, you’ll want to preheat the oven to 425 degrees Fahrenheit. This cooks the asparagus relatively quickly, in about 15 minutes.


Baking asparagus is similar to roasting, but you’ll use a lower temperature and longer cooking time. You’ll want to preheat the oven to 350 degrees Fahrenheit and cook for approximately 20-25 minutes, turning halfway through.


You can also broil asparagus in the toaster oven, though you’ll need to keep a close eye on it so that it doesn’t burn. The toaster oven should be set to 450 degrees Fahrenheit–or 500 degrees if your toaster oven goes that hot.

At this temperature, your asparagus should be cooked in about 10-12 minutes. You’ll want to turn the asparagus spears halfway through the cooking time.

What Happens If You Overcook Asparagus?

If you overcook asparagus it can turn brown, get mushy, and lose some of its flavor. Avoid overcooking by keeping an eye on the asparagus while it is cooking.

If you have cooked your asparagus for too long, the best option is to use it for making asparagus soup!

As Easy as Roasting Asparagus!

As you can see, roasting asparagus can be a simple way to cook this healthy and delicious vegetable. With your toaster oven, you can have this dish prepared in as little as 10 minutes!
