How to Make Sea Bass With Fennel

1
Preheat your skillet or sauté pan over medium-high heat, until it reaches 400 F (200 C). While the pan is heating up, prepare your fennel by slicing it into thin wedges and removing any tough or fibrous parts.
2
Add 2 tbsp of butter to the preheated pan, and let it melt. Once the butter has melted, add the sliced fennel to the pan, and cook for about 3-4 minutes on each side, until it's tender and lightly browned.
3
While the fennel is cooking, prepare your sea bass fillets by seasoning them with salt, pepper, and thyme. Make sure to pat the fillets dry with a paper towel before cooking to help them sear better.
4
Once the fennel is done, remove it from the pan and set it aside on a plate. Add the remaining 2 tbsp of butter to the pan, and let it melt. Then, add the sea bass fillets to the pan, skin side up (if they have skin). Cook for about 3-4 minutes, until the skin is crispy and golden brown.
5
Flip the sea bass fillets over, and cook for another 3-4 minutes, until they reach an internal temperature of 145 F (63 C). Use an instant-read thermometer to check the temperature, and make sure to insert it into the thickest part of the fillet.
6
While the sea bass is cooking, prepare the sauce by squeezing the juice of one lemon into the pan, and adding the white wine. Bring the sauce to a simmer, and let it cook for about 2-3 minutes, until it's reduced slightly and flavorful.
7
Once the sea bass is done, remove it from the pan and set it aside on a plate. Add the cooked fennel back into the pan, and toss it with the sauce to coat. Then, add the chopped parsley and fennel fronds to the pan, and stir to combine.
8
To serve, place a sea bass fillet on each plate, and spoon some of the fennel and sauce over the top. Garnish with a lemon wedge, and serve immediately.
9
Let the sea bass rest for a few minutes before serving, to allow the juices to redistribute and the flavors to meld together.
10
Serve the sea bass with your choice of sides, such as roasted vegetables, quinoa, or a salad. Enjoy!
11
Make sure to not overcrowd the pan, cook the sea bass in batches if necessary, to ensure that each fillet has enough room to cook evenly.
12
Don't overcook the sea bass, it should be cooked until it reaches an internal temperature of 145 F (63 C), and it should still be moist and flaky.
