I was looking for a simple side dish that felt special for dinner one evening. TikTok Viral Recipe? Oh yes. I grabbed some large onions, hollowed them out, and filled them with a savory seasoning mix. As they roasted in the oven, the whole kitchen smelled amazing.
Do I Need to Peel the Onion
Yes, it’s best to peel the onions before stuffing and roasting. The outer layer can be harsh and bitter if left on. Peeling helps the filling flavors soak in better. It also makes the texture softer and easier to eat.
Kind of Onion to Use
Large sweet onions, like Vidalia or Walla Walla, work best for stuffing. They are mild and hold their shape well in the oven. You can also use yellow onions if you prefer a stronger flavor. Avoid small onions, as they don’t hold enough filling.

FULL INSTRUCTIONS WITH STEPS FOR OVEN-ROASTED ONIONS
First Step: Get Oven and Ingredients Ready
Preheat your oven to 375°Fahrenheit (190°Celsius) and prepare a baking dish for the onions. Gather all ingredients and measure them so everything is within reach. Keep a sheet of foil handy for wrapping the onions later.
Second Step: Prep the Onions
Peel each onion and slice about a 1-inch opening at the top. Use a small spoon to scoop out the center, creating a deep well halfway down. Add ½ tablespoon of butter into each hollowed onion for flavor.
Third Step: Make the Spicy Butter Mixture
Melt the remaining butter in a small bowl and stir in chili onion crunch, garlic, paprika, Old Bay, Cajun seasoning, Italian herbs, salt, and pepper. Mix well so the flavors combine evenly. Pour the mixture over the onions, filling the wells and coating the outsides.
Fourth Step: Bake and Finish
Wrap each onion tightly in foil and place them in the prepared baking dish. Bake for 50–60 minutes, until the onions are fork-tender. For a caramelized top, unwrap the foil and broil for 2–3 minutes before serving.
TRICKS AND TIPS:
- Choose the right onions: Pick large, firm onions that are easy to hollow out. Sweet onions work best because they roast nicely and taste mild.
- Prep carefully: Cut the top off and scoop out the inside without breaking the onion. Keep the removed onion flesh to mix into your stuffing for extra flavor.
- Even cooking: Place onions in a baking dish with a little water at the bottom. This helps them cook evenly and prevents them from drying out.
- Add finishing touches: Sprinkle a little olive oil or cheese on top before baking. It gives a golden color and improves the taste.
