Ingredients
- 6 oz Cod Fillet (Skinless, about 1 inch thick; two fillets)
- 3 Tbsp Unsalted Butter (Cut into small pieces for fast melting)
- 1 Tbsp Vegetable Oil (High‑smoke‑point oil for initial sear)
- 2 Garlic Clove (Smash with knife side; keep in large pieces to avoid burning)
- 3 sprigs Fresh Thyme (Woody stems add herbal note; can substitute oregano or marjoram)
- 0.5 tsp Kosher Salt (Pre‑mixed with pepper for quick seasoning)
- 0.125 tsp Ground Black Pepper (Pre‑mixed with salt)
- 1 Lemon (Cut into wedges for serving; optional squeeze)
Instructions
Prepare Ingredients
Pat the cod fillets dry with paper towels, then season both sides with the pre‑mixed kosher salt and black pepper.
Time: PT3M
Heat Oil
Add 1 Tbsp vegetable oil to the skillet and heat over medium‑high until the oil just begins to smoke.
Time: PT2M
Sear First Side
Reduce heat to medium, swirl the pan, then place the fillets skin‑side (the flatter side) down. Press gently with a spatula for 5 seconds to ensure full contact, then cook 4‑5 minutes without moving.
Time: PT5M
Flip and Brief Cook
Using a non‑stick spatula, flip the fillets and cook the opposite side for about 1 minute to firm up.
Time: PT1M
Add Butter and Begin Basting
Scatter the 3 Tbsp butter around the pan. As it melts and begins to brown, tilt the skillet toward you and spoon the melted butter over the fish for 15 seconds.
Time: PT0.5M
Baste on Heat
Return the skillet to the burner and let the fish cook for 30 seconds, then repeat the tilt‑spoon motion for another 15 seconds.
Time: PT0.75M
Add Aromatics
Add the smashed garlic cloves and thyme sprigs to the butter, allowing them to sizzle briefly. Continue the basting cycle: 15 seconds tilt, 30 seconds on heat, repeat once more.
Time: PT1M
Check Internal Temperature
Insert an instant‑read thermometer into the thickest part of each fillet; aim for 130°F (54°C).
Time: PT0.25M
Temperature: 130°F
Finish and Plate
Remove the fillets quickly with two spatulas, drizzle any remaining butter sauce over the top, garnish with fresh thyme sprigs and a lemon wedge.
Time: PT0.5M
