Crispy Red Snapper with Saffron Garlic Butter and Fennel Step-by-step instructions

Before you start

Before cooking, pat the snapper fillets dry and score the skin. Thinly slice the fennel bulb and grate the manchego. Prepare the saffron garlic butter by blooming the saffron in warm water, then melting with the butter and garlic.

Have your lemon wedges and fennel fronds ready for garnish. Set a large cast iron skillet over medium-high heat so it is hot when you start. This mise en place ensures a smooth cooking process.

Instructions

Prep and Sear

1. 1Prep the fish and vegetables
   Pat the red snapper fillets dry with paper towels. Using a sharp knife, score the skin in a few diagonal slashes, about 1 inch apart, being careful not to cut into the flesh. Season both sides with kosher salt and black pepper. Thinly slice the fennel bulb using a mandoline or a sharp chef's knife. Grate the manchego on the large holes of a box grater.
   Look for The fish is dry and scored; fennel is shaved thin; cheese is grated.
   Tip Scoring helps the skin crisp evenly and prevents curling.
2. 2Make the saffron garlic butter
   In a small bowl, combine the saffron threads with 1 tablespoon of warm water and let bloom for 5 minutes. In a separate small pan or microwave-safe bowl, melt the butter with the minced garlic and the saffron mixture. Stir to combine and keep warm.
   Look for The butter is melted, fragrant with garlic and saffron, and slightly golden.
   Tip Bloom the saffron in water to release its color and aroma before adding to the butter.

The fillets are scored, seasoned, and the fennel and cheese are ready. The skillet is hot, and the saffron butter is prepared. When you place the fish skin-side down, you should hear a vigorous sizzle.

The skin will start to turn golden at the edges. The fennel slices are thin and even, and the manchego is fluffy and ready to scatter.

Butter Basting

3. 3Sear the fish skin-side down
   Heat a large cast iron skillet over medium-high heat. Add the olive oil and swirl to coat. Place the snapper fillets skin-side down in the skillet. Press gently with a spatula for a few seconds to ensure even contact. Cook without moving for 3-4 minutes, until the skin is deeply golden and crisp.
   Look for The skin is browned and releases easily from the pan.
   Safe temperature 145°F (63°C) internal temperature (fish)
   Tip Resist the urge to flip too early; the skin will release when crisp.
4. 4Add fennel and saffron butter
   Scatter the sliced fennel around the fish in the skillet. Pour the saffron garlic butter over the fish and fennel. Continue to cook for 2-3 minutes, basting the fish with the butter using a spoon. The fennel should soften slightly but retain some crunch.
   Look for The butter is bubbling, the fennel is fragrant and slightly translucent at the edges.
   Safe temperature 145°F (63°C) internal temperature (fish)
   Tip Baste continuously to keep the fish moist and infuse it with flavor.
5. 5Finish cooking the fish
   Continue to cook the fish for another 2-3 minutes, basting frequently, until the fish is opaque and flakes easily with a fork. The internal temperature should reach 145°F (63°C) when measured with an instant-read thermometer inserted into the thickest part.
   Look for The fish is opaque and flakes, and the skin is very crisp.
   Safe temperature 145°F (63°C) internal temperature (fish)
   Tip If the skin isn't crisp enough, cook an extra minute on the skin side.

The fish is cooking with the fennel and butter. The butter should be bubbling gently, and the aroma of garlic and saffron will fill the kitchen. The fennel will soften and begin to caramelize at the edges. The fish skin should be deeply browned and crisp. Baste frequently to keep the flesh moist and flavorful.

Finish and Serve

6. 6Finish and serve
   Remove the skillet from the heat. Scatter the grated manchego over the fish and fennel. Squeeze fresh lemon juice over everything. Garnish with fennel fronds. Serve immediately, spooning any extra butter from the pan over the top.
   Look for The cheese melts slightly, the lemon brightens, and the fronds add freshness.
   Tip Serve right away so the skin stays crisp.

The fish is opaque and flakes easily, and the internal temperature has reached 145°F (63°C). The cheese is scattered over the top and just beginning to melt. The lemon juice brightens the dish, and the fennel fronds add a fresh green touch. Serve immediately while the skin is still crackling.

Common mistakes

A common mistake is moving the fish too early, which can tear the skin. Let it sear undisturbed until it releases easily. Another is overcrowding the pan; cook the fillets in a single layer with space around them.

Avoid using cold butter straight from the fridge, as it can cool the pan. Also, don't skip scoring the skin—it prevents curling and helps the fat render.

How to tell it’s done

The fish is done when the skin is deeply golden and crisp, and the flesh is opaque and flakes easily with a fork. The internal temperature should read 145°F (63°C) on an instant-read thermometer inserted into the thickest part.

The fennel should be tender-crisp, and the butter should be bubbling and fragrant. The cheese should be just melted, and the lemon adds a bright finish.
