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

Before you start

Before you begin, pat the fish fillets dry with paper towels and score the skin in a few shallow diagonal cuts. Thinly slice the fennel bulb, reserving the fronds for garnish, and grate the manchego cheese on a box grater.

Have the saffron garlic butter at room temperature so it melts quickly in the hot pan. Set a large cast iron skillet over medium-high heat and let it get hot while you finish the prep.

Instructions

Prep and Heat

1. 1Prep the fish and vegetables
   Score the skin of the red snapper fillets in a few shallow diagonal cuts, about 1/4 inch deep, being careful not to cut into the flesh. Thinly slice the fennel bulb, reserving the fronds. Grate the aged manchego on the large holes of a box grater into a pile.
   Look for The fish skin is scored but intact; the fennel is paper-thin; the cheese is fluffy and shredded.
   Tip Pat the fish very dry with paper towels before scoring to help the skin crisp.
2. 2Heat the skillet
   Place a cast iron skillet over medium-high heat and add the olive oil. Swirl to coat the pan and heat until the oil shimmers but does not smoke.
   Look for The oil ripples and lightly shimmers when the pan is ready.
   Tip A hot pan is key to a non-stick sear on the skin.

At the end of this phase, the fish is scored and dry, the fennel is sliced thin, and the manchego is shredded.

The oil in the skillet shimmers but is not smoking, ready for the fish. The aromas of saffron and garlic are waiting in the butter, and everything is in place for a quick, hot sear.

Sear and Baste

3. 3Sear the fish skin-side down
   Lay the snapper fillets in the skillet, skin side down, and press gently with a spatula for a few seconds to ensure even contact. Cook undisturbed for about 4 minutes, until the skin is golden and crisp.
   Look for The skin turns deep golden and releases easily from the pan.
   Tip Resist moving the fish; let the skin set before flipping.
4. 4Add fennel and saffron butter
   Scatter the sliced fennel around the fish and add the saffron garlic butter to the pan. Let the butter melt and foam, then tilt the skillet slightly and use a large spoon to baste the fish with the foaming butter for about 2 minutes.
   Look for The butter foams and turns golden, the fennel softens and begins to caramelize.
   Safe temperature 145°F (63°C) internal temperature (fish)
   Tip Basting continuously keeps the fish moist and infuses it with saffron flavor.
5. 5Finish the fish
   Continue to cook the fish, basting all the while, until the flesh is opaque and flakes easily with a fork and the internal temperature registers 145°F (63°C). The skin should be shatteringly crisp.
   Look for The fish is opaque and flakes; the skin crackles when pressed.
   Safe temperature 145°F (63°C) internal temperature (fish)
   Tip Use an instant-read thermometer to guarantee doneness without overcooking.

The fish skin is deeply golden and crisp, the fennel is softening in the butter, and the sauce is foaming and fragrant. The fish should release easily from the pan, and the flesh should be opaque and flaky. The kitchen smells of saffron, garlic, and browned butter.

Finish and Serve

6. 6Scatter fronds and citrus
   Remove the skillet from the heat. Scatter the chopped fennel fronds over the fish and squeeze the fresh citrus halves over everything, letting the juice sizzle in the pan.
   Look for The citrus juice bubbles and brightens the butter sauce.
   Tip Squeeze just before serving to keep the crisp skin from softening.
7. 7Plate and garnish
   Lift a glistening, butter-basted piece of fish onto a plate, skin side up. Spoon the fennel and pan sauce around it and shower with the shredded manchego cheese. Serve immediately.
   Look for The fish is glossy, the fennel is tender, and the cheese melts slightly on contact.
   Tip Let the fish rest for 3 minutes before serving to allow the juices to settle.

The fennel fronds and citrus juice brighten the dish, and the manchego melts slightly over the warm fish. The plate is glossy and vibrant, with the crisp skin crackling as you lift the fillet. The fish is ready to serve immediately, with the butter sauce spooned around.

Common mistakes

The most common mistakes are using a cold pan, which causes the skin to stick, and flipping the fish too early, which tears the skin. Also, be careful not to overcook the fish, as it can become dry.

When adding the butter, lower the heat slightly to prevent it from burning, and baste continuously to keep the fish moist. Finally, do not crowd the pan; cook the fillets in a single layer so they sear properly.

How to tell it’s done

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

The skin should be deep golden and crackling, and the fennel should be tender but still slightly al dente. The butter sauce should be glossy and bubbling, with a fragrant aroma of saffron and garlic.
