These roasted onions are an easy, flavorful, budget-friendly side dish that can be prepared in advance. They’re perfect for the holidays or whenever you’re craving some sweet, caramelized oniony goodness.
Ingredients in these roasted onions
You can use any type of onions you like for this recipe. Sweet onions or red onions are my top choices, but any variety will work.
Dried thyme gives these onions a lovely aroma and warm, cozy flavor. You can substitute dried rosemary instead if you prefer.
I used extra virgin olive oil in this dish but you can substitute any other neutral oil you prefer.
How to make them
These onions are easy to make and can be prepared in advance, which makes them the perfect addition to a holiday feast or any other special occasion meal. These baked onions are a great, easier alternative to caramelized onions, which are traditionally made on the stovetop and require a lot of stirring and attention to ensure they don’t burn.
To make these oven baked onions, start by preheating the oven to 350 degrees Fahrenheit, then roughly chop the onions.
Add the chopped onions, thyme, olive oil, salt, and pepper to a large baking dish (mine is 9 x 13 inches, but any similar size is fine). Use your hands or a spoon to toss the onions, ensuring they’re evenly coated with oil.
Bake at 350 degrees Fahrenheit for thirty minutes, then mix thoroughly before continuing to bake for thirty additional minutes or until the onions are golden brown around the edges.
Storage
Store these roasted onions in an airtight container in the fridge for up to three days, then reheat before serving or enjoy them at room temperature.
