These unique Italian onions possess a mild flavor and beautiful golden surface after roasting, making them perfect for holiday dinners, everyday feasts, and vegan menus alike.
Why Roast Cippolini Onions?
- Rich, Sweet Flavor: Roasting brings out the natural sugars, producing a deliciously sweet taste with a balanced savory edge.

- Versatile Side Dish: Complements roasted meats, hearty grains, and rich sauces.
What Are Cippolini Onions?
Cippolini onions, sometimes spelled cipollini, are small, flat, and disc-like compared to their rounder cousins. Originating from Italy, their name translates to ”little onion” in Italian. Cippolini are valued for their higher sugar content, exceptional for caramelization, and their delicate bite once cooked. Their thin skin and compact size make them distinctive in both look and culinary use.
How to Choose and Prepare Cippolini Onions
To make the most of roasted cippolini onions, proper selection and preparation are essential. Here’s what to look for and how to ready them for the oven:
- Look for:
- Firm bulbs free of soft spots
- Glossy, papery skins without excessive blemishes or mold
- Uniform size for even roasting
- Prep Steps:
- Trim: Slice off the root and stem ends for easier peeling.
- Peel: Gently remove the outer papery skins. Soak briefly in warm water if skins are sticky.
- Wash: Rinse under cold water and pat dry thoroughly.
Ingredients for Roasted Cippolini Onions
The ingredient list is remarkably short, allowing the pure flavor of the cippolini onions to shine through. Here’s what you need:
Ingredient | Quantity | Notes |
---|---|---|
Cippolini onions | About 1 pound | About 12–16 small onions |
Olive oil | 3 tablespoons | Extra virgin recommended |
Kosher salt | 1 teaspoon | To taste |
Freshly ground black pepper | ½ teaspoon | To taste |
Optional: fresh herbs (thyme, rosemary, sage) | 1–2 sprigs | Optional add-in for aroma |
Step-by-Step Roasting Instructions
Transform simple onions into a stunningly tasty side by following these straightforward steps.
- Preheat the Oven:
- Heat to 400°F (204°C). This temperature is ideal for caramelizing and softening the onions.
- Toss with Oil and Seasoning:
- In a large mixing bowl, combine cleaned onions and olive oil.
- Sprinkle salt and pepper over the top.
- Toss until each onion is evenly coated; add herbs if desired.
- Arrange on Baking Sheet:
- Place onions in a single layer, cut side facing down, on a parchment-lined rimmed baking sheet. This ensures maximum caramelization.
- Roast:
- Bake for 25-30 minutes, flipping onions halfway through until they’re golden, soft, and deeply caramelized.
- Serve:
- Transfer to a serving plate. Enjoy immediately or at room temperature for best flavor and texture.
Tips for the Best Roasted Cippolini Onions
- Don’t overcrowd the pan: Overlapping leads to steaming, not roasting.
- Even sizing is critical: Select onions of similar size for uniform doneness.
- Parchment paper helps prevent sticking and encourages even browning.
- High heat is essential for concentrated flavor and caramelization.
- Finish with acid: A splash of balsamic vinegar or lemon juice before serving can balance sweetness.
Serving Suggestions
Roasted cippolini onions are impressively adaptable. Here’s how to let them shine:
- Holiday Sides: A sophisticated partner to roasts, turkey, and glazed ham.
- Vegetarian Centerpiece: Add to grain bowls, salads, or serve over polenta for vegan feasts.
- Pasta and Risotto: Fold into creamy risotti or toss with rustic pastas and shaved cheese.
- On Toast: Top crisp sourdough or crostini with roasted onions and ricotta or goat cheese.

Make Ahead and Storage
- Make Ahead: Roast onions up to 2 days in advance. Refrigerate in an airtight container.
- Reheating: Warm gently in a skillet over low heat or in the microwave. If needed, drizzle with extra olive oil to restore gloss and moisture.
- Freezing: Not recommended as the onions may lose their texture after thawing.

- Spices: Add a sprinkle of smoked paprika, cumin, or cracked black pepper for savory warmth.
