Nutmeg-Kissed Creamed Spinach

• 3/4 cup half-and-half (or 1/2 cup milk + 1/4 cup heavy cream)
• 1/4 cup finely grated Parmesan cheese
• 1/8 tsp freshly grated nutmeg
• 1/2 tsp kosher salt and 1/4 tsp black pepper

• 1 tsp finely grated lemon zest (for garnish)

Step-by-Step Instructions

Step 1: Preheat and Prep the Cod

Preheat the oven to 425°F. Line a rimmed baking sheet with parchment for easy cleanup. Pat the cod fillets dry on all sides with paper towels. Place them on the prepared sheet, rub with 1 tbsp olive oil, and season evenly with 1/2 tsp kosher salt and 1/4 tsp black pepper. Set aside while you make the crumb topping.

Step 2: Toast the Lemon-Herb Breadcrumbs

In a large skillet over medium heat, melt 2 tbsp butter with 1 tbsp olive oil. Add 1 cup panko and cook, stirring frequently, until the crumbs are pale golden and smell toasty, 3–4 minutes. Stir in 1 minced garlic clove and cook 30 seconds. Take the pan off the heat and immediately mix in 1 tsp lemon zest, 2 tbsp parsley, 1 tsp fresh thyme, 1/4 tsp kosher salt, and 1/8 tsp black pepper. Transfer to a bowl so the crumbs stay crisp.

Step 3: Start the Silky White Beans

In a medium saucepan over medium heat, warm 2 tbsp olive oil. Add the minced shallot and cook until softened and translucent, 2–3 minutes. Stir in 2 minced garlic cloves for 30 seconds. Add the rinsed cannellini beans, 3/4 cup warm broth, 1/2 tsp kosher salt, a pinch of red pepper flakes (optional), and 1/4 tsp pepper. Simmer gently for 5–6 minutes to heat through and soften.

Step 4: Mash the Beans Until Velvety

Off the heat, mash the beans with a potato masher until mostly smooth and creamy, leaving a little texture. Stir in 1 tbsp lemon juice and 1 tbsp butter (optional for extra silkiness). If the mash seems thick, loosen with a splash of warm broth. Taste and adjust salt and pepper. Cover and keep warm on low heat, stirring occasionally.

Step 5: Crown and Bake the Cod

Divide the lemon-herb breadcrumbs over the tops of the cod fillets, pressing lightly to help them adhere. Bake at 425°F until the fish flakes easily with a fork and reaches 130–135°F in the thickest part, about 10–12 minutes depending on thickness. For deeper color, broil for 30–60 seconds at the end, watching closely.

Step 6: Make the Nutmeg-Kissed Creamed Spinach

While the cod bakes, wipe out the breadcrumb skillet and melt 1 tbsp butter over medium heat. Whisk in 1 tbsp flour and cook 30 seconds. Gradually whisk in 3/4 cup half-and-half and simmer until lightly thickened, 1–2 minutes. Add the baby spinach in batches, tossing until wilted and saucy, 2–3 minutes. Stir in 1/4 cup Parmesan, 1/8 tsp nutmeg, 1/2 tsp salt, and 1/4 tsp pepper. Adjust consistency with a splash of half-and-half if needed.

Step 7: Plate and Finish with Lemon

Give the beans a final stir and adjust seasoning. Spoon a generous swoosh of the silky mash onto warm plates, set a breadcrumb-topped cod fillet over each, and add a scoop of creamed spinach alongside. Finish with a fine sprinkle of fresh lemon zest and a light drizzle of extra-virgin olive oil. Serve immediately.

Pro Tips

• Dry fish equals crisp topping: thoroughly pat cod dry so the crumbs stay crunchy.
• Pre-toast the panko: toasting in butter and oil guarantees a golden, flavorful crust in the short bake time.
• Warm your broth: adding warm liquid to the beans helps them turn silky without cooling down.
• Cook cod to temperature, not just time: pull at 130–135°F for moist, flaky fillets.
• Balance richness with acid: a touch of lemon juice in the beans and zest on top keeps the dish bright.

Variations

• Herb swap: use dill and chives instead of parsley and thyme; add 1 tbsp capers to the crumbs for briny punch.
• Gluten-free: use gluten-free panko and thicken the spinach with 2 tsp cornstarch slurry instead of flour.
• Different fish: haddock, pollock, or halibut work well; adjust bake time for thicker fillets.

Storage & Make-Ahead

Breadcrumbs can be toasted up to 1 day ahead; store airtight at room temperature and stir in the fresh herbs and zest just before using. The mashed beans keep 3 days refrigerated; reheat gently with a splash of warm broth and a drizzle of olive oil. Creamed spinach keeps 2 days; reheat over low heat with a bit of half-and-half. Cooked cod is best fresh but can be refrigerated up to 2 days; re-crisp the topping under a quick broil, watching closely. Not recommended for freezing due to texture changes.
