3. Toss the chopped potatoes with 1 tablespoon olive oil, 1 teaspoon salt, and black pepper.

5. While the potatoes roast, melt the butter with the remaining 1 tablespoon olive oil in a medium saucepan over medium heat.
6. Add the shallot and saute for about 5 minutes, until soft.
7. Stir in the garlic and cook for 1 minute, just until fragrant.
8. Pour in the cream, stock, rosemary sprigs, lemon zest, lemon juice, Dijon mustard, cayenne, and capers.

Variations and Add Ins

Cod potatoes rosemary cream sauce takes changes well, so treat the recipe above as a starting point rather than a set of rules. These are the swaps we come back to most often.

• Use a different fish. Any firm white fish works, so buy whatever looks best that day.
• Add citrus. A squeeze of lemon or lime right at the end wakes everything up.
• Make it creamy. A splash of cream or a spoonful of cream cheese turns it into comfort food.
• Add herbs. Fresh dill, parsley or basil brighten the whole plate.
• Change the herbs. Fresh parsley, basil or dill at the end each send it somewhere slightly different for no extra effort.
• Make it a bigger meal. Serve it over rice or with warm bread and it stretches to feed another person or two.

Change one thing at a time rather than three. That way you find out what you actually like in this dish instead of guessing at the end.

How to Store and Reheat Cod Potatoes Rosemary Cream Sauce

Seafood is best the day it is made, but leftovers keep in an airtight container in the refrigerator for up to two days. Reheat gently and briefly, since seafood turns firm quickly with too much heat.

If you are cooking ahead on purpose, prep the components and keep them separate until you are ready. It takes a few minutes off a busy evening and the recipe holds its texture far better that way.
