Crispy Pancetta Brussels Sprouts with Caramelized Onions

A savory side dish that transforms humble Brussels sprouts into something irresistible.

Fresh parsley and butter finish the dish with brightness and silky texture. Perfect for weeknight dinners or holiday meals, this recipe showcases how proper technique can make Brussels sprouts appealing even to skeptics.

FAQ

Can I make this without pancetta?

Yes, you can omit the pancetta for a vegetarian version. Add a bit more olive oil and salt to compensate for the lost richness and seasoning.

What if my Brussels sprouts are browning too quickly?

Lower the heat to medium and ensure the sprouts aren't overcrowded in the pan. You want them to caramelize, not burn.

How long will leftovers keep?

Store covered in the refrigerator for up to 3 days. Reheat gently in a skillet to restore some crispness to the sprouts.
