Which Onions are Best for Cooking?
The short answer is all of them are great for cooking, roasting, and baking. It all depends on the flavor you want in your dish. Yellow onions are your standard cooking onion and is your safest bet if the type of onion isn’t specified in a recipe. Flavor is strong and pungent, so not the best in raw settings. Sweet Onions are often found in the store as Vidalias and Walla Walla onions. These are great for something that needs raw onions because they are mild with a touch of sweetness. The perfect choice for onion rings. Red onions add great color to a dish and are awesome raw because of their sweet, peppery flavor. Use red onions for roasting, grilling, and pickling. White onions have a mild flavor with less of an aftertaste than it’s counterparts which makes them great for salsa, potato salad, and Mexican food.
Can You Bake Onions?
Absolutely! In fact, baking and roasting onions are the best way to allow the natural sugars of the onion shine and reduce the sharpness. You can slice them and bake them like in these Parmesan Roasted Onions, or you can even wrap them in foil with some oil and seasoning and bake them whole! Obviously, the sliced onions will cook faster than the whole onion.
How to Cut an Onion into Rings
The first step is to peel the whole onion and cut off the non-root end. Now you have two options. If you are confident with your knife skills, start at the non-root end and cut 1/4″ slices that run parallel to the ends of your onion. If you are still working on your knife skills, you can cut a very thin slice off the side of the onion to create a flat surface to put on the cutting board, creating a bit more stability for cutting a round object. You will lose a complete ring or two this way, but it will be safer.

- 3–4 medium onions
- Extra virgin olive oil – about 3 tablespoons
- Kosher salt – about 1 1/2 teaspoons
- Freshly ground black pepper – about 1/2 teaspoon
- 1 cup heavy cream
- 1/2 cup freshly grated parmesan cheese
1. Preheat oven to 375 degrees and lightly spray a large cookie sheet with sides (jelly roll pan). Peel the onions and slice them into 1/4 inch slices, keeping the rings intact. Lay them on the cookie sheet and drizzle with olive oil, then salt and pepper. Roast uncovered in the oven for 15 minutes.
2. Remove the onions from the oven. Raise the oven temperature to 450 degrees. Transfer onions to a baking dish that has been sprayed with nonstick spray. You may have to slightly overlap the onions to make them all fit. Pour the cream over the top of the onions then generously sprinkle with the fresh parmesan cheese.
4. Cover with foil and return to the oven for another 20 minutes. Remove the foil and allow the onions to brown for about 10-15 minutes more.
