Cod with Mushroom and Spinach Sauce is one of my favourite weeknight meals. It’s quick, easy and, although there is cream in this recipe, still pretty healthy with the spinach and mushrooms. It’s also seriously delicious. The recipe multiplies easily so whether it’s dinner à deux with chilled bubbles, a kitchen supper for four with kid friendly mocktails or a dinner party for six with a nice bottle of chilled white wine, you’ll have supper on the table in under half an hour.
A Very Versatile Recipe
I can get lovely sustainably fished cod loins locally but if sustainable cod isn’t available where you are, you can use any filleted white fish. Don’t like fish? Use roast chicken breasts instead.
I almost always serve this with frozen organic peas. If you have very hearty appetites round the table try adding crushed new potatoes or some Basmati rice as well.
As you can see from the watermark on the photograph below, I’ve been making this recipe for a very long time. It featured on the blog before, but I just had to bring my Cod with Mushroom and Spinach Sauce back front and centre because it really is so very good!
Cod with Mushroom and Spinach Sauce Recipe
After putting the fish in the oven, simply fry up the onions and mushrooms in a large frying pan, sprinkle with some flour and then stir in and cook for a couple of minutes, stirring constantly.
Stir in the stock a bit at a time allowing the sauce to thicken after each addition. Add the spinach and allow to wilt.
Gradually stir in the cream, a bit at a time, until a smooth, pourable consistency is reached. Add a bit more stock if necessary, taste for seasoning and serve the Mushroom and Spinach Sauce over the cooked cod.
Cod with Mushroom and Spinach Sauce really is that easy! I hope you enjoy this recipe as much as my family, friends and I do.

- If the sauce becomes to thick, add a bit more chicken or fish stock.
- Taste the sauce for seasoning and add salt and pepper if necessary.
- Remove the fish from the foil packages, place on a plate and serve the spinach and mushroom sauce over top.
