🦐 Ingredient Notes & Substitutions
- 1.5 pounds of cod fillet. Cod has a mild flavor and dense, flaky, white meat. Some good substitutes for cod are Haddock, Pollack, Tilapia, Black Cod, Striped Bass, Hake, Mahi Mahi, and Grouper.
- 2 tablespoon olive oil. I prefer organic olive oil but feel free to use avocado oil, coconut oil, or even butter or margarine.
- 1 cup of mushrooms, chopped. I prefer fresh mushrooms, but I also use canned mushrooms and dried mushrooms.
- ½ onion, chopped. I use red onions, but white, yellow, and green onions are great substitutes.
- 3 cloves of garlic, finely chopped. Again, I prefer fresh garlic. If you don't have fresh, substitute ½ teaspoon of garlic powder for 3 cloves of fresh garlic, or 1.5 teaspoon of minced garlic.
- 1.5 cups of shrimp. Make sure it is peeled with the tail removed and chopped.
- 3 tablespoon butter or margarine. Feel free to use olive oil, avocado oil, or coconut oil.
- 3 tablespoon flour. I used whole wheat flour. You could also use all-purpose flour as well.
- ½ teaspoon salt. Use less salt if on a low-sodium diet.
- ⅛ teaspoon pepper.
- ½ teaspoon paprika.
- 2 tablespoon parmesan cheese.
- 1.5 cup of milk. I used 1% milk. Alternatively, you could also use any kind of milk you prefer. Some good non-dairy options to try are coconut milk, soy milk, and almond milk.
- 2 tablespoon lemon juice (optional). This really gives it a distinct lemon flavor. HOWEVER, this may make your milk curdle, which happened to me. Not to worry, though; it just requires an extra step. If it curdles, carefully pour the sauce into a blender and blend it up for 30 seconds. Pour it back into the pot.
🔪 Instructions
Preheat oven to 400 degrees Fahrenheit. Lightly grease a 9x13 baking dish. Place the cod fillets in a baking dish. Sprinkle salt and pepper on each fillet. Use less salt if on a low-sodium diet. Then, bake, covered, for 15 minutes.
Next, make the delicious sauce. In a large frying pan, saute 1.5 cups of shrimp with ½ onion and three garlic cloves in 1 tablespoon of olive oil for about 5 minutes. Continue to cook until the shrimp turns pink. Add 1 cup of sliced mushrooms to the shrimp mixture and saute for 3-4 minutes.
In a separate pan, melt 3 tablespoons of butter or margarine over medium-low heat. Add 3 tablespoons of flour. Whisk together until smooth. Add ½ teaspoon salt, ⅛ teaspoon pepper, ½ teaspoon paprika, and 2 tablespoon parmesan cheese to the butter and milk mixture.
Whisk steadily and pour in 1.5 cups of milk. Continue to heat until the mixture begins to thicken.
If you would like a little bit of lemon flavor to your sauce, add 2 tablespoon of lemon juice. HOWEVER, this may make your milk curdle. If this happens, not to worry; just pour the sauce mixture into a blender and blend it up for 30 seconds. Done! Add it back to the pot.
Add sauce to the mushroom and shrimp mixture. Mix well. Pour over the fish, and bake for an additional 15 minutes or so. Fish will be done when it flakes with a fork. Thick fillets will take longer to cook. The internal temperature of the fish should be 145 F with a meat thermometer.
Serve with extra sauce spooned over the fish. Enjoy!
🥗 Side dishes
- Grilled or steamed vegetables.
- Instant Pot Rice is my favorite side dish to serve with this creamy sauce.
- Potatoes, either mashed (try my Twice-Baked Mashed Potatoes), baked (try my Smoked Baked Potatoes), or Crispy Oven-Roasted Potatoes.
- Garden Salad, Panera Tomato Basil Cucumber Salad, or Easy Greek Cucumber Salad.
- Pasta of your choice.
🌡️ Storage
If you have any leftovers (we never do), let the fish cool for no more than 1 hour, then place in a container with a tight-fitting lid. Keep in the fridge for not more than two days. Rewarm in the oven or on the stove in a pot.
Expert Tips
- To prevent curdling when adding the lemon juice to milk, temper the milk by adding a small amount of lemon juice to it first, then add the rest.
- Use freshly grated Parmigiano-Reggiano for the best flavor.
- Garnish with a sprinkle of fresh parsley or fresh dill before serving.
