Frequently Asked Questions
Can I use frozen cod and shrimp?
Yes, frozen seafood works perfectly. Thaw it completely in the refrigerator overnight, or place the sealed packages in a bowl of cold water for about 30 minutes for shrimp and slightly longer for cod. Pat them extremely dry before cooking. Excess moisture from thawing can water down the sauce and prevent a good sear on the fish.
What if I don’t have heavy cream?
You can substitute a mixture of ½ cup whole milk and ¼ cup melted butter, whisked together, to approximate the richness of heavy cream. The sauce will be slightly thinner. You can also use half-and-half, but watch it carefully as it’s more prone to curdling at high heat. For a dairy-free option, full-fat canned coconut milk creates a creamy, slightly sweet sauce that pairs well with the seafood.
Can I use only one type of seafood?
Absolutely. This sauce is fantastic with just cod, just shrimp, or just about any seafood. You can make a double batch of cod, or increase the shrimp to a full pound. Scallops, halibut, salmon, and even mussels or clams work beautifully. The cooking times will vary slightly for different types and thicknesses, so adjust accordingly and always cook to the proper internal temperature.
My sauce curdled—what went wrong?
Curdling can happen if the heat is too high, if an acidic ingredient like lemon juice is added too early, or if lower-fat dairy is used. To avoid this, simmer the cream gently, add the lemon juice off the heat or at the very end, and use heavy cream. If your sauce does curdle, you can sometimes rescue it by removing the pan from the heat and whisking vigorously, or by adding a small splash of cold cream while whisking. The flavor will still be good, though the texture may be slightly grainy.
Is this dish gluten-free?
Yes, the recipe is naturally gluten-free. The sauce is thickened with Parmesan and cream, with no flour or roux. Always check labels on packaged ingredients (like pre-grated cheese or stock if you add any) to ensure they don’t contain hidden gluten. Serve with gluten-free sides like rice, potatoes, or gluten-free pasta for a complete gluten-free meal.
Shrimp and Cod in Creamy Garlic Sauce
An elegant, restaurant-quality dinner of tender cod and juicy shrimp in a velvety garlic cream sauce with Parmesan and lemon. Ready in just 20 minutes and perfect for any occasion.
Prep Time:
10 minutes
Cook Time:
10–15 minutes
Total Time:
20–25 minutes
Servings:
4
Ingredients
- 2 cod fillets (about 6 oz each, 12 oz total), patted dry
- ½ lb large raw shrimp, peeled and deveined, patted dry
- Salt and freshly ground black pepper
- 2 tablespoons unsalted butter
- 4 garlic cloves, minced
- ¾ cup heavy cream
- ¼ cup freshly grated Parmesan cheese
- Juice of ½ lemon (about 1 tablespoon)
- 2 tablespoons chopped fresh parsley
- Optional: pinch of red pepper flakes
Instructions
- Season the seafood: Pat the cod and shrimp completely dry with paper towels. Season both sides of the cod fillets and the shrimp generously with salt and pepper.
- Sear the cod: Heat the butter in a large skillet over medium-high heat until melted and foamy. Place the cod fillets in the skillet and sear for 3–4 minutes per side, until golden. Transfer the cod to a plate (it will finish cooking later).
- Build the sauce: Reduce heat to medium-low. Add the minced garlic to the same skillet and cook for 30–60 seconds until fragrant. Pour in the heavy cream, scraping up any browned bits. Simmer gently for 2–3 minutes until slightly thickened. Stir in the Parmesan until melted and smooth.
- Cook the shrimp: Add the seasoned shrimp to the sauce in a single layer. Cook for 1–2 minutes per side until pink and opaque. Nestle the cod fillets back into the skillet, spoon sauce over the top, cover, and simmer on low for 3–5 minutes until the cod flakes easily and the shrimp are cooked through.
- Finish and serve: Remove from heat. Squeeze the lemon juice over the dish and sprinkle with fresh parsley. Taste and adjust seasoning. Serve immediately over rice, pasta, or with crusty bread to soak up the sauce.
Notes
- For a dairy-free version, substitute the butter with olive oil, use full-fat coconut milk instead of heavy cream, and omit the Parmesan (or use a dairy-free alternative).
- You can use any firm white fish: halibut, haddock, tilapia, or even salmon all work well.
- Leftovers can be refrigerated for up to 2 days; reheat gently on the stovetop with a splash of cream or milk to loosen the sauce.
- To add vegetables, toss in a handful of fresh spinach or chopped sun-dried tomatoes along with the garlic.
