Parmesan Brussels Sprouts in Air Fryer
An amazingly easy and perfect side dish for dinner or Thanksgiving table like this roasted butternut squash. It is crispy with a parmesan crust and tastes fantastic.
Secrets to crispiness - Even in the oven, they can turn out soggy especially if the pan is too crowded or the heat isn’t high enough. This recipe avoids both pitfalls and ensures they come out crisp every single time.
One pound was perfect to cook in a 6 quart air fryer without over crowding and at medium high heat of 375 degrees without burning them.
If you like them al dente or tender all the way through, we have a trick up our sleeves to make them softer in the center.
What Makes These So Good?
- Minimal ingredients - Brussel Sprouts along with basic pantry ingredients and nothing fancy.
- Vegetarian - They are made without bacon, making it perfect for everyone.
- Amazing Texture - Perfectly seasoned, crisp on the outside and tender on the inside!
- Flavorful - Although they use only basic ingredients, they are still packed with flavor.
How Long To Roast
It depends on the temperature, the size of your sprouts and how tender you want the vegetable. They are ready to eat when they are lightly charred, crisp on the outside, and tender on the inside. We cooked them at 375 degrees for 7 to 9 minutes.
How Do You Prepare For Roasting?
When buying from the store, look for prepackaged bag. They are occasionally available on stalks in season, but are often much more expensive. They are in season from October through March but you can usually find them at your local grocer year-round.
Look for bright heads that are firm, tightly wrapped and heavy for it's size. Avoid ones with yellowing leaves or black spots, which could be a sign of fungus. Smaller heads are usually sweeter and more tender than larger ones.
If you are purchasing them in advance, to keep them fresh, store them unwashed, and untrimmed in a plastic bag in the vegetable crisper drawer of the fridge.
Begin by giving them a good rinse in cold water. Using a sharp knife, cut off the tough brown ends and discard them. Remove any outer yellow, brown or discolored leaves. Cut large ones in half and leave small ones whole, so they are similar in size for even cooking.
Do You Need to Soak Them?
Not for this recipe! Several online recipes call for pre soaking them for about 10 minutes, so they cook more tender inside. The soak time tenderizes the sprouts so the middles are softer.
We have an alternate trick up our sleeves to cook them softer, which is to add some water into the basket before adding the sprouts. As the water gets hot, it creates steam and helps with cooking them all the way through.
Can I Use Frozen Ones?
Sure can! As with most vegetables, fresh is better than frozen. But, if you have is only frozen, then make sure not to defrost or thaw them before cooking. Just use them frozen and prepare as described in the recipe. You will have to increase cooking time by about 5 minutes depending on the size. They tend to be a bit softer, but still taste good.
Ingredients You'll Need (Scroll down to the bottom of the post for full recipe)
Here’s a basic list of the ingredients you’ll need. As always, you can find the full printable recipe in the box below.
- Brussels Sprouts – Fresh ones preferably
- Melted Butter - Use unsalted butter or use good quality olive oil instead.
- Parmesan Cheese – shredded or grated
- Seasonings - Salt, Black pepper, garlic powder and red pepper flakes.
There are a few key things to remember when roasting any type of vegetable
- Cut into even size pieces - Cut larger ones into halves and leave small ones whole. This makes sure that they all cook evenly at the same time.
- Don't overcrowd - Make sure not the over crowd the basket, so they can crisp up.
- Move them together for the second half - Make sure to move the sprouts closer together (but still in one layer) before topping with cheese. This will make sure that the most of the cheese stays on top of the vegetable without falling into the basket.
- Parmesan - Use freshly grated for best results. They will melt into the sprouts making them so tasty. Pre grated has much less flavor with a dry texture. (unfortunately, we could not find fresh grated when making this recipe and had to opt for pre shredded.
- Pat them dry - After washing make sure to pat them completely dry so the butter will coat them better and crisp up.
- Give a shake - Shake the basket once in between ensures even cooking.
- Wash well - Give them a good rinse then pat them dry with paper towels. If there's any water, then they will steam instead of roasting and not get as crisp.
- Spread them out - Make sure to spread them out evenly or cook in batches if using a smaller air fryer.
