Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Mix mashed avocado, almond flour, 1 tbsp dill, lemon zest, 1/4 tsp sea salt, and 1/8 tsp black pepper in a bowl.
  2. Step 2: Press avocado mixture evenly over both sides of cod fillets, pressing gently to adhere.
  3. Step 3: Place cod on a greased baking sheet and bake for 15-18 minutes until the crust is golden and cod flakes easily.
  4. Step 4: While cod bakes, melt butter in a small saucepan over medium heat. Add remaining lemon juice, 1 tbsp dill, and 1/8 tsp black pepper, whisking until slightly thickened.
  5. Step 5: Drizzle lemon-dill sauce over cod immediately before serving and garnish with extra dill.

How do I store leftover Avocado-Crusted Cod with Lemon-Dill Sauce?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Avocado-Crusted Cod with Lemon-Dill Sauce?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Avocado-Crusted Cod with Lemon-Dill Sauce for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
