This Creamy Garlic Seafood Bake with Shrimp and White Fish is a rich, elegant dinner made with tender white fish, juicy shrimp, garlic, herbs, Parmesan, and a smooth cream sauce. The seafood cooks gently in the sauce until the fish is flaky and the shrimp are just tender, while the top develops light golden color.
It looks restaurant-style, but the preparation is straightforward enough for a weeknight dinner, date night, holiday meal, or special family occasion.
Why This Recipe Is Popular
Creamy seafood recipes are popular because they feel luxurious without necessarily requiring complicated techniques.
White fish provides a mild, tender base. Shrimp adds sweetness and texture. Garlic and herbs give the sauce depth, while Parmesan adds a savory finish.
Another advantage is versatility. You can serve this seafood bake with rice, mashed potatoes, pasta, crusty bread, or vegetables.
It also works well as a dinner-party recipe because the presentation looks impressive while most of the work can be done in one baking dish.

Ingredients
For the Seafood
1½ pounds firm white fish, cut into large pieces
1 pound large shrimp, peeled and deveined
1 tablespoon olive oil
½ teaspoon salt
½ teaspoon black pepper
½ teaspoon garlic powder
¼ teaspoon paprika
For the Creamy Garlic Sauce
3 tablespoons unsalted butter
5 garlic cloves, finely minced
1½ cups heavy cream
½ cup low-sodium seafood or chicken broth
¾ cup freshly grated Parmesan
1 teaspoon Dijon mustard
1 tablespoon fresh lemon juice
1 teaspoon lemon zest
1 tablespoon chopped parsley
1 tablespoon chopped fresh dill
½ teaspoon black pepper
How to Choose the Best Fish
Firm white fish works best because it holds together during baking.
Cod is one of the easiest choices.
Haddock provides a slightly stronger flavor.
Halibut is firmer and more luxurious.
Avoid very thin fillets because they can overcook quickly.
Cut the fish into relatively large chunks so they remain juicy.
Prepare the Seafood
Pat the fish and shrimp dry with paper towels.
This is important because excess surface moisture can dilute the sauce.
Season with salt, black pepper, garlic powder, and paprika.
Set aside while preparing the sauce.
Prepare the Creamy Garlic Sauce
Preheat the oven to 400°F (200°C).
Melt the butter in a skillet over medium-low heat.
Add the minced garlic.
Cook for approximately 30 seconds, just until fragrant.
Do not let it brown heavily.
Pour in the broth.
Add the heavy cream.
Stir in Dijon mustard, black pepper, and lemon zest.
Allow the sauce to gently simmer for several minutes.
Do not boil aggressively.
Add the Parmesan
Reduce the heat.
Gradually add freshly grated Parmesan while stirring.
Continue stirring until the sauce becomes smooth and slightly thicker.
Freshly grated Parmesan usually melts more smoothly than pre-shredded cheese.
Add the parsley and dill.
Finish with lemon juice.
Taste and adjust seasoning.
Assemble the Seafood Bake
Arrange the white fish pieces in a lightly greased baking dish.
Place the shrimp around and between the fish pieces.
Pour the creamy garlic sauce evenly over everything.
Try to keep most of the seafood partially visible rather than completely submerged.
Sprinkle a small amount of additional Parmesan over the top if desired.
Bake Until Tender
Bake for approximately 15–20 minutes, depending on the thickness of the fish.
The shrimp should turn opaque and pink.
The fish should flake easily with a fork.
Fish is safely cooked when it reaches an internal temperature of 145°F (63°C).
Avoid overcooking because both shrimp and fish can become tough when exposed to excessive heat.
How to Get a Light Golden Top
If the seafood is cooked but you want more color, switch the oven to broil for approximately 1–2 minutes.
Watch constantly.
Cream sauces and Parmesan can brown quickly.
The goal is a lightly golden surface, not a dark crust.
Secret to Tender Seafood
The biggest secret is timing.
Shrimp and white fish cook much faster than chicken or beef.
Do not rely on a long bake.
Start checking early.
Large fish pieces help because they remain moist longer than small cubes.
Also, avoid boiling the cream sauce before baking.
Gentle heat keeps the sauce smooth and reduces the risk of overcooking the seafood.
How to Keep the Sauce Smooth
Use heavy cream rather than low-fat milk for the most stable sauce.
Add Parmesan gradually.
Keep the heat moderate.
Freshly grated cheese melts more evenly.
Lemon juice should be added near the end rather than boiled aggressively because too much acid over high heat can sometimes affect cream sauces.
Creamy Garlic Shrimp-Only Variation
For a shrimp-only version, omit the fish.
Use approximately 2 pounds of large shrimp.
Reduce the baking time because shrimp cook quickly.
Begin checking after approximately 8–10 minutes.
Serve with rice or pasta.
Salmon and Shrimp Variation
Replace the white fish with salmon.
Cut the salmon into large chunks.
Salmon’s richer flavor works very well with cream, garlic, dill, and lemon.
Because salmon is naturally richer, you may prefer slightly less Parmesan.
Spinach Seafood Bake
Add approximately 2 cups fresh baby spinach.
Wilt the spinach briefly in the garlic butter before adding the cream.
This adds color and gives the sauce a slightly fresher flavor.
Mushroom Seafood Bake
Sauté approximately 8 ounces sliced mushrooms before adding the garlic.
Allow them to brown and release moisture.
Then proceed with the sauce.
Mushrooms add a deeper savory flavor that works particularly well with white fish.
Spicy Creamy Seafood Bake
Add:
¼ teaspoon crushed red pepper flakes
Small pinch of cayenne
Additional black pepper
Keep the spice moderate so it does not overpower the seafood.
What to Serve With Creamy Seafood Bake
This dish works beautifully with simple side dishes.
Serve it with:
Jasmine rice
Mashed potatoes
Buttered noodles
Linguine
Roasted potatoes
Steamed broccoli
Asparagus
Green beans
Crusty bread
Rice and mashed potatoes are particularly good because they absorb the creamy garlic sauce.
How to Serve With Pasta
Cook linguine, fettuccine, or penne separately.
Place the pasta in bowls.
Add fish and shrimp.
Spoon generous amounts of creamy sauce over the top.
Finish with Parmesan, parsley, and black pepper.
A small squeeze of fresh lemon before serving adds brightness.
Make-Ahead Instructions
The sauce can be prepared slightly ahead.
Cool and refrigerate it.
The seafood should remain refrigerated separately.
For the best texture, assemble and bake the dish shortly before serving.
Do not leave raw seafood sitting in cream sauce at room temperature.
Meal Prep and Storage
Seafood is best eaten fresh, but leftovers can be stored.
Allow the dish to cool somewhat.
Transfer it to airtight containers.
Refrigerate promptly.
For best quality, eat within approximately 2–3 days.
Cream sauce thickens when cold, so this is normal.
Best Way to Reheat
Reheat gently.
Place the seafood and sauce in a covered skillet over low heat.
Add a small splash of cream or broth.
Warm just until hot.
Avoid boiling.
The microwave can work, but use short intervals to avoid overcooking the shrimp.
Can You Freeze Creamy Seafood Bake?
Freezing is possible, but it is not ideal.
Cream sauces may separate slightly, and seafood can become softer after thawing.
For best quality, this dish is better refrigerated and eaten within a few days.
If you do freeze it, use within approximately 1 month and thaw overnight in the refrigerator.
Common Mistakes to Avoid
Overcooking the shrimp: They become rubbery quickly.
Cutting the fish too small: Larger pieces stay juicier.
Using wet seafood: Pat it dry before cooking.
Boiling the cream sauce aggressively: Gentle heat keeps it smoother.
Adding Parmesan too fast: Add gradually.
Using too much lemon early: Add acidity near the end.
Skipping fresh herbs: Parsley and dill make the dish taste fresher.
Frequently Asked Questions
What fish works best?
Cod, haddock, halibut, pollock, or another firm white fish works well.
Can I use frozen seafood?
Yes. Thaw it safely in the refrigerator and pat it completely dry before cooking.
Can I use scallops?
Yes. Large scallops are an excellent addition, but do not overcook them.
Can I use milk instead of heavy cream?
You can, but the sauce will be thinner and less stable. Half-and-half is a better substitute.

Mozzarella will melt, but Parmesan gives the sauce more flavor. A combination can work.
How do I know when the shrimp are done?
They should be opaque and pink with a gentle curve.
Can I add vegetables?
Yes. Spinach, mushrooms, broccoli, asparagus, or peas work well.
Can I serve this with rice?
Absolutely. Rice is one of the best sides because it absorbs the sauce.
