Ingredients
- 4 large onions (yellow or sweet Vidalia) – choose firm bulbs that are close in size for even cooking.
- 2 tablespoons olive oil – coats and helps caramelize, use extra-virgin for bright flavor.
- 2 tablespoons unsalted butter – adds that silky, indulgent finish; substitute vegan butter for a dairy-free version.
- 1 tablespoon honey or maple syrup – deepens the onion’s natural sweetness; omit for lower sugar.
- 1/2 cup vegetable or chicken broth – keeps the onions moist and creates a little pan sauce.
- 1/4 teaspoon smoked paprika – optional, for a whisper of smokiness.
- Salt and freshly ground black pepper – to taste.
- Fresh thyme or parsley, chopped – for garnish and herbal brightness.
Substitutions: nutritional yeast – adds cheesy flavor without dairy if you want a savory crust; balsamic vinegar – swap for honey to add tang and complexity.

Step-by-Step Instructions
- Preheat the oven to 375°F (190°C). Line a baking dish with parchment for easier cleanup.
- Peel the onions, leaving the root end intact to hold the layers together. Trim just enough from the top to expose the layers.
- In a skillet over medium heat, warm the olive oil and butter until the butter melts and foams. Add the honey and smoked paprika, stirring once to combine.
- Brush the onion bases with the oil-butter mixture, then place the onions in the baking dish standing upright.
- Pour the broth into the bottom of the dish (not over the onions) — this will create steam and a delicious jus as they bake.
- Cover tightly with foil and bake for 30 minutes. At this point your kitchen will smell amazing; the edges will be soft.
- Remove the foil, baste the onions with the pan juices, and continue baking uncovered for 20–30 minutes until the edges are deeply golden and the centers are tender and spoonable.
- Finish with a sprinkle of salt, pepper, and fresh thyme or parsley. Serve immediately and savor the first spoonful of sweet, buttery onion.
Tips and Variations
- Festive twist: top with crumbled goat cheese and toasted walnuts for holiday elegance.
- Indulgent dessert-style play: drizzle a little extra maple syrup and sprinkle flaked sea salt for a sweet-and-salty finish.
- Healthier alternative: skip the butter and use extra olive oil; use low-sodium broth.
- Make it smoky: add a few drops of liquid smoke or a sprinkling of smoked sea salt.
- Stuffed version: cut a shallow well in the center after par-cooking and fill with breadcrumbs, herbs, and a little grated cheese, then return to the oven until golden.
Serving Suggestions
This Baked Onion Recipe is wonderfully adaptable. For a cozy supper, serve alongside roasted root vegetables, crusty bread, or creamy mashed potatoes. For a heartier, comfort-leaning plate, pair with a rich grain like the baked cheese risotto — the creamy risotto soaks up the sweet jus beautifully. If you want a protein partner, the onion’s sweetness complements roasted chicken or a savory casserole; try it with my baked garlic butter chicken with mozzarella for a crowd-pleasing combination. Pour a light red wine or a honeyed white to echo the onion’s caramel notes.
Storage and Make-Ahead Tips
- Refrigerator: Store leftovers in an airtight container for up to 3 days. Reheat gently in a low oven or microwave until warmed through.
- Freezing: Slice and freeze in a freezer-safe container for up to 2 months; thaw overnight in the fridge before reheating.
- Make-ahead: You can par-bake the onions (covered) up to 24 hours ahead, then uncover and finish baking right before serving for best texture.
Pro Tips from the Kitchen
- Choose sweet onions for a naturally higher sugar content that caramelizes beautifully.
- Keep the root end intact while baking to help the onion hold its shape.
- Use the pan jus: spoon it over finished onions and mashed sides — it’s concentrated flavor gold.
- If you prefer a deeper caramelized crust, finish under the broiler for 1–2 minutes while watching closely.
- Let the onions rest for a few minutes after baking to settle the juices for cleaner serving.
FAQs
Q: Can I use red onions or shallots instead of yellow onions?
A: Absolutely. Red onions become sweet and slightly fruity when baked, while large shallots are more delicate and make a beautiful side. Cook times may be a bit shorter for smaller onions.
Q: Is this recipe vegan-friendly?
A: Yes, with simple swaps. Replace butter with vegan butter or extra olive oil and use vegetable broth to keep it plant-based.
Q: How do I know when the onions are done?
A: They are ready when a knife passes easily through to the center and the layers feel tender and spoonable. The outer edges should be golden and slightly crisp.
Q: Can I double the recipe for a crowd?
A: Yes. Use a larger baking dish, keep the onions in a single layer, and increase the broth slightly. Cooking time may be similar; check for tenderness.
