Prep and Cook Time
- Readiness Time: 15 minutes
- Cooking Time: 12 minutes
- Total Time: 27 minutes
Yield
Serves 4 generous portions
Difficulty Level
Easy to Medium – perfect for weeknight dinners or elegant weekend entertaining
Ingredients
- 1.5 lbs fresh cod fillets, skin removed, patted dry
- 4 tbsp unsalted butter, divided
- 2 cloves garlic, finely minced
- 1 tbsp fresh lemon juice
- 4 cups fresh baby spinach leaves, washed and dried
- 1 ripe avocado, peeled and pitted
- 1/4 cup full-fat Greek yogurt
- Salt and freshly ground black pepper, to taste
- 1 tbsp olive oil
- Fresh dill or parsley sprigs, for garnish
Instructions
- Prepare the Avocado Puree: In a food processor, combine avocado, spinach, Greek yogurt, lemon juice, and a pinch of salt. Blend until smooth and creamy. If needed,add a splash of water or olive oil to reach a silky consistency. Reserve chilled.
- Season the Cod: Lightly sprinkle both sides of the cod fillets with salt and pepper, ensuring even coverage for flavor enhancement.
- Heat the Skillet: In a large non-stick skillet, melt 2 tablespoons of butter with 1 tablespoon olive oil over medium heat to prevent burning and promote golden crust formation.
- Sear the Cod: Gently place fillets in the hot skillet, cooking undisturbed for about 4 minutes until the bottom turns golden brown. Flip carefully using a spatula.
- Add Garlic Butter: Add remaining 2 tablespoons butter and minced garlic around the fish. Spoon the melting garlic-butter mixture over the fillets as they cook for another 3-5 minutes until the fish is opaque and flakes easily.
- Rest the Fish: Remove cod from skillet and let it rest for 2 minutes. This helps the juices redistribute, keeping the fillets tender and moist.
- Plate and Serve: Spoon a generous dollop of creamy spinach & avocado puree onto warmed plates and gently lay the buttered cod fillets on top. Garnish with fresh dill or parsley for an aromatic finish.
Tips for Success
- Choosing Cod: Opt for wild-caught cod when possible; it tends to have a firmer texture and superior flavor compared to farmed. Look for firm flesh and a subtle briny scent.
- Prevent overcooking: Cod cooks quickly – keep an eye on the edges as they turn opaque to avoid drying out your fillets.
- Avocado Ripeness: Use perfectly ripe avocados to ensure a creamy,luscious puree without lumps or bitterness.
- Make-Ahead: The avocado puree can be prepared up to 4 hours ahead and kept refrigerated, just cover tightly with plastic wrap to prevent browning.
- Substitutions: Baby kale or Swiss chard can replace spinach for a more robust green flavor, and coconut yogurt works well as a non-dairy option.
Serving Suggestions
Serve the buttered cod atop the creamy spinach & avocado puree with a wedge of lemon on the side for added brightness. Pair this dish with a light quinoa salad or roasted baby potatoes for a balanced meal. To enhance the presentation, drizzle a touch of extra virgin olive oil over the puree and sprinkle microgreens or edible flowers for vibrant color contrasts. Crisp, toasted sourdough is also delightful for soaking up any buttery sauce left on the plate.

- ½ cup heavy cream
- ¼ cup grated Parmesan cheese
- Salt and freshly ground black pepper, to taste
- Pinch of freshly grated nutmeg

- Melt the butter over medium heat in a large skillet until it foams and begins to turn golden, about 2 minutes. This butterous base primes the spinach for a rich, silky finish.
- Add the minced garlic and sauté for 30 seconds until fragrant, careful not to brown it as it will turn bitter.
- add the baby spinach in batches, stirring and wilting it down until all is incorporated, about 3-4 minutes. The spinach should be tender but still vibrant green for the best texture.

- Do not overcook the spinach; wilt it just enough to keep a slight bite and bright color.
- For a dairy-free version, substitute heavy cream with coconut cream and parmesan with nutritional yeast while maintaining the same cooking process.
- To make ahead, prepare the creamy spinach and cool it completely. Reheat gently over low heat,stirring in a splash of cream or milk to revive the texture.
- If the spinach mixture seems dry, a little more cream or a teaspoon of olive oil will enrich the velvety feel without thinning the blend.
