Why This Fennel and Black Olive Fish Is a Winner
This dish is the ultimate choice for a romantic date night. It feels sophisticated but only takes 35 minutes from start to finish. You get restaurant-quality flavors with minimal cleanup since it uses one skillet.
It is also the perfect healthy reset after a weekend of indulgence. The fennel adds a sweet crunch that balances the salty Kalamata olives. Your body will thank you for this nutrient-packed meal that actually tastes incredible.

Simple Method
We start by getting a quick sear on those fish fillets. This locks in the moisture and creates a beautiful golden crust. Then, we sauté the fennel until it is perfectly tender and sweet.
A splash of white wine deglazes the pan to catch every bit of flavor. Everything finishes in the oven for a few minutes to marry the tastes. Even if you are a seafood beginner, you can master this easily.
Ingredients You’ll Need
This recipe relies on fresh seasonal produce and high-quality pantry staples.
- 4 white fish fillets (6 oz each) such as cod or sea bass
- 2 large fennel bulbs, thinly shaved
- 0.5 cup Kalamata olives, pitted and halved
- 2 tablespoons extra virgin olive oil
- 3 cloves garlic, minced
- 0.25 cup dry white wine
- 1 tablespoon fresh lemon juice
- 1 teaspoon lemon zest
- 0.5 teaspoon kosher salt

Step-by-Step

- Heat 1 tablespoon of olive oil in an oven-safe skillet over medium-high heat.
- Sear the fish for 2 to 3 minutes per side until golden, then remove from the pan and set aside.
- Add the remaining oil to the skillet and sauté the shaved fennel for 5 minutes until softened.
- Stir in the garlic and olives, cooking for 1 minute until fragrant.
- Deglaze the pan with white wine and lemon juice, scraping the bottom of the pan to release browned bits.

Best Ways to Enjoy It
Serve this fish immediately while it is hot and flaky. I love pairing it with a side of crusty sourdough bread. You will want that bread to soak up the delicious pan juices.
A simple side of roasted asparagus or a light green salad works perfectly too. If you want something heartier, serve it over a bed of fluffy couscous. It is the perfect spring meal for any occasion.
Keep It Fresh
Fish is always best served fresh from the oven. If you have leftovers, store them in an airtight container. Keep them in the fridge for up to two days. Reheat gently in a pan over low heat to avoid overcooking the fish. Do not use the microwave if you can help it.
Tips for Best Results
- Use a mandoline to get the fennel bulbs paper-thin for the best texture.
- Make sure your skillet is hot before adding the fish to get a crust.
- Pat the fish dry with paper towels for a better golden sear.
- Choose a dry white wine like Pinot Grigio or Sauvignon Blanc for deglazing.
- Don’t toss the fennel fronds; they are packed with fresh flavor.
- Check the fish early to ensure it stays juicy and tender in the oven.
- Use high-quality olive oil to enhance the Mediterranean flavor profile.
- Always use fresh lemon juice rather than the bottled stuff for brightness.
Make It Your Own
- Swap Kalamata olives for buttery Castelvetrano olives for a milder taste.
- Add a pinch of red pepper flakes for a spicy kick in the sauce.
- Use halibut or snapper if you can’t find cod or sea bass nearby.
- Stir in some cherry tomatoes for extra sweetness and vibrant spring color.
- Finish with a drizzle of balsamic glaze for a sweet and tangy touch.
Quick Answers
Can I use frozen fish?
Yes, just make sure to thaw it completely first. Pat it very dry before seasoning and searing. Frozen cod works great for this easy recipe.
What if I don’t like olives?
You can swap them for capers to keep that salty bite. Or just leave them out and add extra lemon zest instead.
What does fennel taste like?
Fennel has a mild, sweet anise or licorice flavor. When sautéed, it becomes very mellow and perfectly complements seafood.
