What Kind Of Onions To Use
When they are in season (April – August), I especially love to use Vidalia onions for this recipe. Any kind that is labelled sweet onion in the store though will work well though. Look for onions that are similar in size.
Do I Need To Make Homemade Stuffing?
These stuffed onions are definitely extra delicious when you start with my homemade stuffing recipe. But I wanted this to be a really easy side dish to make, so a boxed stuffing mix works great too and is actually what I ended putting in the recipe card below.
How To Make Stuffed Onions
Start by preheating your oven to 450°F while you prepare your onions. You’ll want to slice about ½-inch off the top of each onion and a small amount from the root end to allow them to sit flat in the baking dish. Peel off onion skin and dispose.
Turn them into stuffable onions by using a spoon or melon baller to scoop out the inside of each onion. You’ll want to leave two to three of the outer layers intact. Mince the onion portions that you have scooped out and set aside.
Sprinkle the onion bowls inside and out with salt. Transfer them, hallowed-out side up, to a 9×12-inch baking dish, then start on your stuffing.
Prepare the stuffing according to the directions on the box and then stir in the reserved minced onion. Fill each onion with about ¼ cup of the stuffing. Divide any remaining stuffing evenly between onions. Pile it up, you don’t want to waste any tasty stuffing!
Distribute the butter pieces in the baking dish around the onions, then cover the baking dish tightly with aluminum foil. Place your dish in oven and bake for 35 minutes. Remove foil and continue to bake uncovered until onions are soft and the stuffing and onions are lightly browned, about 25 minutes more.
Baste the onions with the browned butter drippings from the bottom of the casserole and serve. It’s so delicious and makes a wonderful side dish to a variety of meals. Try it with roast chicken, pork chops, or even meatloaf.
Can I Make Air Fryer Stuffed Onions?
Yes, this stuffed onion recipe actually works great in the air fryer! However, I could only fit four at a time in my air fryer, so you may need to work in batches.
Instead of using butter, spray the stuffed onions with oil before going into the air fryer. Cook at 400°F for 25 minutes. You’ll need to cover the stuffing with foil for the first 20 minutes to prevent it from burning. If you’re working in batches, remove the first batch and cover with foil or keep in a warm oven until ready to serve.
