Ingredients You’ll Need
These ingredients are straightforward but each plays a starring role in creating the perfect balance of flavor, texture, and color in this recipe. From the crunchy freshness of the fennel bulbs to the bright punch of the agrodolce sauce, every element counts.
- 2 medium fennel bulbs: Choose firm bulbs with bright green fronds for the freshest flavor and crunch.
- 3 tablespoons extra virgin olive oil: This enriches the fennel during roasting, helping it caramelize beautifully.
- 1 teaspoon sea salt: Enhances natural flavors; adjust according to your taste preference.
- 0.5 teaspoon freshly ground black pepper: Adds a subtle warmth without overpowering the dish.
- 1 tablespoon granulated sugar: Sweetens the agrodolce sauce, balancing its tanginess perfectly.
- 2 tablespoons white wine vinegar: Brings a bright acidity that lifts the whole dish; apple cider vinegar works as well.
- 2 tablespoons capers: Impart a briny kick, giving the sauce its signature punch.
- 2 tablespoons fresh parsley: Roughly chopped for a fresh, herbal garnish that adds color and freshness.
How to Make Simple Roasted Fennel with Agrodolce Sauce Recipe
Step 1: Preheat the Oven
Begin by setting your oven to 400°F (200°C). This temperature is ideal for roasting fennel to achieve that tender interior and caramelized, slightly crispy exterior that’s so irresistible.
Step 2: Prepare the Fennel
Trim away the stalks and fronds from the fennel bulbs, which you can save for garnish or add to salads if you want. Slice each bulb in half lengthwise, then cut into even wedges. This ensures each piece cooks evenly and gets that lovely roasted texture.
Step 3: Toss Fennel with Seasoning
In a large bowl, combine your fennel wedges with the extra virgin olive oil, sea salt, and freshly ground black pepper. Toss everything gently but thoroughly so each piece is well coated. This step is crucial because the oil promotes caramelization while the salt and pepper enhance natural flavors.
Step 4: Arrange for Roasting
Spread the seasoned fennel wedges out on a baking sheet lined with parchment paper. Spacing them out properly gives the heat room to circulate, resulting in perfectly roasted pieces without steaming.
Step 5: Roast to Perfection
Roast the fennel for 25-30 minutes, flipping the pieces halfway through to ensure even browning on all sides. You’ll know they’re done when the wedges are tender, nicely caramelized, and simply bursting with flavor.
Step 6: Make the Agrodolce Sauce
While the fennel is roasting, start your agrodolce sauce in a small saucepan. Combine the granulated sugar and white wine vinegar over medium heat. Stir until the sugar dissolves completely and let the mixture simmer gently for about 5 minutes to develop a rich, syrupy consistency.
Step 7: Add Capers
Stir in the capers and let the sauce simmer for an additional minute. This not only softens their bite but also infuses the sauce with their briny, tangy character, rounding out the sweetness and acidity beautifully.
Step 8: Combine and Garnish
Drizzle the finished agrodolce sauce over your roasted fennel while it’s still warm. Sprinkle the fresh parsley on top for a vibrant pop of color and a subtle, herby note that elevates the whole dish.
Step 9: Ready to Serve
Serve this dish warm either as a standout side or a light main. The combination of textures and flavors is sure to impress anyone lucky enough to try it.
How to Serve Simple Roasted Fennel with Agrodolce Sauce Recipe

Garnishes
Fresh parsley is a classic, but you can also try finely chopped chives or a sprinkle of toasted pine nuts for added crunch. A few fennel fronds left aside from prep can serve as an elegant, edible garnish that underscores the dish’s star ingredient.
Side Dishes
This simple roasted fennel pairs beautifully with grilled meats like chicken or pork, or alongside roasted potatoes and a crisp green salad. Its bright agrodolce sauce cuts through richer dishes, making it a perfect companion for heavier mains.
Creative Ways to Present
For a fun twist, serve the roasted fennel on a bed of creamy polenta or mix it into warm grains like farro or barley. You might also plate it alongside a spread of antipasto items such as olives, artichokes, and cured meats to create a vibrant Mediterranean-style platter.
Make Ahead and Storage
Storing Leftovers
Let any leftovers cool to room temperature before placing them in an airtight container. Stored in the refrigerator, the roasted fennel with agrodolce sauce will keep well for up to 3 days without losing its flavor or texture.
Freezing
This dish can be frozen, but keep in mind the texture of fennel may soften further upon thawing. If you choose to freeze, store it in a freezer-safe container for up to a month, and thaw overnight in the fridge for best results.
Reheating
Reheat gently in a 350°F oven or a skillet over medium-low heat to maintain its caramelized edges and prevent sogginess. Microwave reheating works too but may result in softer fennel and less crispness.
FAQs
Can I use a different type of vinegar in the agrodolce sauce?
Absolutely! While white wine vinegar gives a bright, clean flavor, apple cider vinegar is a great alternative. Both bring the necessary acidity needed to balance the sweetness of the sugar.
What if I don’t have capers on hand?
If you’re out of capers, you can substitute with chopped green olives for a similar briny punch, or omit them entirely and just adjust the seasoning to taste – the sauce will still be delicious.
Is fennel available year-round?
Fennel is typically in season during fall and winter, but many grocery stores carry it year-round imported from other regions. Choose bulbs that are firm and without any brown spots for the best results.
How can I tell when the fennel is done roasting?
When roasted properly, fennel should be tender enough to pierce with a fork and have golden brown caramelized edges. It will smell sweet and slightly nutty as it cooks.
Can I make the agrodolce sauce ahead of time?
Yes, the sauce can be made a day ahead and refrigerated. Simply reheat gently before drizzling over the roasted fennel to bring back its luscious texture and flavor.
