storage/reheating

Store leftovers in an airtight container in the refrigerator for up to 2 days.

Avoid microwaving shrimp and fish as it can lead to rubbery texture.

FAQs

What is the best type of fish for this recipe?

Firm white fish like cod, halibut, or sea bass work best as they hold up well during searing.

Can I use frozen shrimp?

Yes, just thaw completely and pat dry before cooking to ensure a good sear.

How do I make the mashed potatoes extra creamy?

Use warm heavy cream and plenty of butter, and mash or whip while the potatoes are still hot.

Can I grill the fish instead of searing?

Yes, grilling is a great option for a smoky flavor. Just brush with oil and grill 3–4 minutes per side.

Is it possible to make this dairy-free?

Yes, use plant-based butter and milk alternatives for the mashed potatoes and sauce.

What sauces go well with this dish?

Lemon butter, white wine garlic, or a light dill cream sauce are all excellent choices.

How can I tell when the fish is done?

Fish is done when it flakes easily with a fork and turns opaque in the center.

Can I use pre-cooked mashed potatoes?

Yes, you can reheat and season store-bought or pre-made mashed potatoes for convenience.

Can I add cheese to the mashed potatoes?

Absolutely. Parmesan or cream cheese adds richness and extra flavor.

How do I prevent the shrimp from overcooking?

Cook shrimp just until pink and firm—about 2 minutes per side. Remove from heat immediately.
