How to Make Air Fryer Brussels Sprouts with Balsamic Glaze, Parmesan, and Walnuts Recipe

Step 1: Prep the Brussels Sprouts

Start by trimming the ends off the Brussels sprouts and removing any tough or damaged outer leaves. Cut each sprout lengthwise into quarters to ensure every piece cooks evenly and crisps up nicely. This prep is crucial for getting that irresistible texture you want from an air-fried vegetable.

Step 2: Toss with Olive Oil and Seasoning

Place your quartered Brussels sprouts into a large bowl, drizzle with olive oil, then sprinkle on the salt and pepper. Use your hands or a spatula to toss everything thoroughly, making sure each sprout is well coated. This step ensures even cooking and seasonings balanced throughout every bite.

Step 3: Air Fry to Crispy Perfection

Transfer the seasoned sprouts to your air fryer basket and set the temperature to 360°F. Cook for 15 minutes, but importantly, shake or toss the basket halfway through. This encourages even browning and avoids any spots getting soggy. When done, the sprouts should be beautifully caramelized on the edges while tender inside.

Step 4: Add the Finishing Touches

As soon as the Brussels sprouts come out of the air fryer and are still hot, sprinkle the shaved Parmesan cheese over the top. Drizzle with the balsamic glaze for that signature tang, then scatter the toasted, salted walnuts. The heat will slightly melt the cheese and meld all the wonderful flavors together.

Garnishes

Side Dishes

This dish shines as the perfect companion to nearly any main. Think grilled chicken, roasted pork tenderloin, or even a hearty vegetarian grain bowl. The sweet and savory notes of the Brussels sprouts pair especially well with rich proteins and creamy starches like mashed potatoes or polenta.

Creative Ways to Present

You can also sprinkle a few fresh herbs like parsley or thyme on top to add a splash of color and fresh aroma that complements the balsamic glaze beautifully.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers from the Air Fryer Brussels Sprouts with Balsamic Glaze, Parmesan, and Walnuts Recipe, store them in an airtight container in the refrigerator. They will keep well for up to 3 days, allowing you to enjoy this delicious dish even after your initial cooking day.

Freezing

It’s best to avoid freezing air-fried Brussels sprouts as the texture can become mushy upon thawing. However, if you must, freeze them in a single layer on a baking sheet first before transferring to a freezer-safe bag to minimize clumping. Reheat gently to retain some crispness.

Reheating

To reheat leftover Brussels sprouts and keep them crispy, simply pop them back into the air fryer at 350°F for 3-5 minutes. This will refresh their texture much better than microwave reheating, which tends to make them soggy.

FAQs

Can I use frozen Brussels sprouts for this recipe?

While fresh Brussels sprouts work best for optimal texture, you can use frozen if needed. Just thaw and pat them dry thoroughly before tossing with oil and seasoning. This helps prevent excess moisture, which can lead to sogginess.

What kind of balsamic glaze should I use?

Look for a high-quality balsamic glaze or reduction that is not too sugary but has a balanced tang and sweetness. You can also make your own by simmering balsamic vinegar until it thickens to a syrupy consistency if you prefer homemade.

Are walnuts the only nut option for this recipe?

Not at all! While toasted walnuts provide lovely crunch and flavor, you could substitute pecans, almonds, or even pine nuts depending on your preference or what you have on hand.

Is this recipe suitable for a vegan diet?

To make this dish vegan, simply omit the Parmesan cheese or substitute with a vegan Parmesan alternative. The rest of the ingredients are all plant-based and naturally delicious.

How can I make the Brussels sprouts extra crispy?

Make sure the sprouts are dry before oiling them, don’t overcrowd the air fryer basket, and toss halfway through cooking. These tips help maximize crispiness in your Air Fryer Brussels Sprouts with Balsamic Glaze, Parmesan, and Walnuts Recipe.
