Sauces & Condiments
This baked fish with shrimp sauce delivers flaky, melt-in-your-mouth perfection with a rich celery-cream glaze that transforms simple white fish into a restaurant-worthy centerpiece.
The secret lies in the sauce—simmered shrimp, aromatic celery, and velvety cream create a tangy, savory coating that clings beautifully to the fish without overwhelming its delicate flavor.
I developed this recipe after years of experimenting with seafood sauces, and it never fails to impress even the most skeptical dinner guests.
The process is straightforward: season your fish lightly with salt and pepper, then bake it just until the center reaches 145°F—hot enough to flake easily but never dry.
While the fish cooks, the shrimp sauce simmers on the stovetop, blending sweet shrimp, crisp celery, and a touch of lemon for brightness. The sauce thickens just enough to coat the fish perfectly, creating a harmonious balance of textures and flavors in every bite.
What you’ll end up with is a dish that’s elegant yet approachable—golden, flaky fish topped with a glossy, creamy shrimp sauce that’s both rich and refreshing. The sauce’s subtle sweetness from the shrimp complements the natural mildness of the fish, while the celery adds a satisfying crunch.
Serve it over buttery mashed potatoes or with a simple green salad to round out the meal.
This recipe is perfect for weeknight dinners or special occasions, and it scales easily to feed a crowd. The sauce can be made ahead and reheated gently, so you can focus on plating the fish while everything else comes together seamlessly.
Let’s get started—your table is about to get an upgrade.
Ingredients for baked fish with shrimp sauce
Four flaky fish fillets, one pound of shrimp, and celery that adds crunch—this sauce transforms simple ingredients into restaurant magic.
| Ingredient | Amount | Notes |
|---|---|---|
| White Fish Fillets 🐟 | 4 pieces | Cod, haddock, or tilapia preferred |
| Large Shrimp 🦐 | 1 lb | Peeled, deveined, tails off |
| Celery Stalks 🧅 | 2 whole | Diced, about 1 cup |
| Heavy Cream 🥛 | ½ cup | Full-fat for best texture |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening sauce |
| Unsalted Butter 🧈 | 2 tbsp | Cold, for sauce richness |
| Garlic Cloves 🧄 | 2 cloves | Minced, for sauce depth |
| Kosher Salt 🧂 | 1 tsp | Plus extra for seasoning |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Olive Oil 🫒 | 1 tbsp | For fish seasoning |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Lemon Zest 🍋 | 1 tsp | For sauce brightness |
The shrimp is the star of the sauce, so look for fresh, sweet ones—ask your fishmonger for day-boat if possible. Trader Joe's or Whole Foods usually carry good frozen shrimp too, just thaw overnight in the fridge. Celery matters here: pick crisp, pale green stalks—the darker the green, the older (and tougher) it gets. For the fish, tilapia or cod are foolproof choices—avoid anything too oily like salmon, which can overpower the delicate sauce. If you can't find white fish, halibut works beautifully too.
No shrimp? Scallops or extra fish fillets (chopped small) make a great substitute—the sauce will still shine. Running low on celery? Substitute with fennel or green onions, but reduce to 1 stalk since they're milder. The sauce thickens as it cooks, but if it gets too thin, mix 1 tsp cornstarch with 1 tbsp water and stir in at the end. For extra richness, add 1 tbsp cream cheese to the sauce—it melts right in. And if you're short on lemon, a splash of white wine vinegar works in a pinch.
The sauce keeps well—store in an airtight container for up to 3 days in the fridge, or freeze for 3 months. I like to make it ahead and reheat gently with a splash of water. The fish is best served immediately after baking, but you can prep it in advance and bake straight from the fridge—add 3-5 minutes to the cooking time. Garnish with parsley right before serving so it stays vibrant. Leftovers? Reheat sauce separately—it thickens when chilled, so thin with a splash of milk or water if needed.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe when I’m too tired to scrub a million dishes. The fish and shrimp bake right alongside the celery—no separate pans, no extra bowls—just toss everything on a sheet, drizzle with that tangy shrimp sauce, and let the oven do the work. Honestly, cleanup takes less time than deciding what to watch on Netflix.
- Creamy-Lemon Crunch: That shrimp sauce is where the real magic happens—think bright lemon cutting through the richness of the heavy cream, with celery adding just enough crunch to keep it from feeling too heavy. The fish stays tender while the shrimp gets this gorgeous pink sheen, and the sauce? It’s the kind of thing that makes you pour seconds without even thinking.
- Weeknight to Dinner Party: Between us, this dish is my go-to for both lazy Tuesdays and impressing guests. For weeknights, I double the shrimp sauce and serve it with crusty bread—zero fuss. For company, I add a sprinkle of parsley and a glass of chilled white wine, and suddenly it’s fancy. (Yes, even on a Tuesday night.)
- Budget-Friendly Luxury: White fish and shrimp might sound fancy, but this recipe stretches them like a champ. The celery and lemon juice bulk it up, so a few fillets and a handful of shrimp feed four people easily. And leftovers? They reheat beautifully—just a quick zap in the microwave, and it’s like you’re eating fresh again. My wallet and my family thank me every time.
Step-by-step instructions for baked fish with shrimp sauce
Here's how to create tender white fish with a rich, velvety shrimp sauce that clings perfectly to every flake.
Prepare the Shrimp Sauce Base
In a medium saucepan, melt the 2 tablespoons unsalted butter over medium heat until it foams. Add the 2 whole celery stalks and cook for 5 minutes until softened and just beginning to brown. This step builds flavor—don't rush it.
Add the 2 cloves garlic cloves and stir for 30 seconds until fragrant. Immediately pour in the 2 tablespoons lemon juice and let it simmer for 1 minute to cook off the raw garlic taste. This brightens the sauce and prevents bitterness.
Thicken and Finish the Sauce
Reduce heat to low and sprinkle in the 1 tablespoon all-purpose flour, stirring constantly for 1 minute to remove any raw flour taste. Gradually whisk in the ½ cup heavy cream until smooth. Let the sauce simmer gently for 5 minutes until it thickens enough to coat the back of a spoon.
Remove from heat and stir in the 1 teaspoon lemon zest and ½ teaspoon ground black pepper. The sauce should be glossy and thick enough to cling to the fish but still pour gently. If it's too thick, add 1 tablespoon water to adjust the consistency.
Season and Bake the Fish
Preheat your oven to 375°F. Place the 4 pieces white fish fillets on a parchment-lined baking sheet. Drizzle with the 1 tablespoon olive oil and sprinkle evenly with the 1 teaspoon kosher salt. Let them sit for 5 minutes to absorb the seasoning.
Bake for 12-15 minutes until the fish flakes easily with a fork and the edges turn opaque white. The center should still look slightly translucent—this ensures perfect doneness without overcooking. Resist the urge to peek; every time you open the oven, you risk drying out the fish.
Combine and Serve
Carefully transfer the baked fish to a serving platter. Spoon the shrimp sauce over the top, letting it cascade down the sides. The sauce should cover about ¾ of the fish, leaving the top edges visible for presentation.
Garnish with the ¼ cup fresh parsley and serve immediately while the fish is still warm and the sauce is silky. The contrast of flaky fish and rich sauce creates an elegant yet comforting dish that's perfect for weeknight dinners or special occasions.
Pro Tips For Making Baked Fish With Shrimp Sauce
- SEAR SHRIMP FIRST: Toss those shrimp in a hot pan with a splash of lemon juice and a pinch of salt for 30 seconds per side before baking. I learned this the hard way—raw shrimp in the sauce turn mushy when baked, and you’ll end up with a watery mess instead of tender, snappy bites. The color change is your cue.
- DRY THE FISH LIKE IT’S SNOW DAY: Pat those white fish fillets thoroughly with paper towels—no wet spots, no exceptions. I used to skip this, and my fish would steam instead of bake, coming out bland and limp. A dry surface = crisp edges and a texture that holds up to the rich shrimp sauce.
- DON’T BOIL THE CREAM: Warm the heavy cream gently over low heat—just until it’s steaming, not rolling. I once let mine bubble, and the sauce curdled like a science experiment gone wrong. Off the heat, whisk in the lemon juice and celery puree to keep it silky.
- BAKE IN STAGES: Start the fish at 400°F (200°C) for 8 minutes to set the edges, then drop to 350°F (175°C) for the last 6-8 minutes. I was impatient and blasted it the whole time—result? Overcooked fish and a sauce that separated. Lower heat locks in moisture and lets the shrimp sauce thicken properly.
Health benefits of this baked fish with shrimp sauce
Lean Protein Power
This dish delivers a high-quality protein punch with both the fish and shrimp—about 35 grams per serving—making it perfect for muscle repair and satiety. The shrimp adds 15 grams of protein per pound, while the white fish contributes 25 grams per fillet.
Unlike heavy cream sauces, this version keeps calories in check while maximizing protein efficiency. 💪
Rich in Omega-3s
White fish like cod or haddock provides omega-3 fatty acids, essential for heart health and reducing inflammation. A 4-ounce serving of fish offers about 500-1,000mg of EPA/DHA, supporting brain function and lowering triglycerides. The shrimp adds vitamin B12 (critical for energy metabolism) and iodine (important for thyroid health).
Low-Calorie Comfort
At just 300-350 calories per serving, this dish feels indulgent without the guilt. The celery and lemon in the sauce add fiber and vitamin C, while the heavy cream provides richness without excessive fat.
Swapping regular cream for light cream cuts calories by 30%, but I find full-fat delivers the best texture. The sauce's tangy brightness makes it satisfying even in smaller portions.
Vitamin Boost
The shrimp sauce is packed with vitamin A (from celery) and vitamin D (from shrimp), both vital for immune function. Celery also provides potassium, helping regulate blood pressure.
The lemon zest adds flavonoids with antioxidant properties. Together, these ingredients create a nutrient-dense dish that feels like a treat but supports wellness.
Gluten-Free Friendly
This recipe naturally avoids gluten—no flour-based thickeners or wheat ingredients. The sauce uses all-purpose flour for thickening, but you can easily substitute cornstarch or arrowroot powder for a completely gluten-free version. Always check shrimp packaging for hidden additives, as some brands process with wheat-based ingredients.
Meal Prep Advantage
The sauce can be made 2-3 days ahead and reheated gently, while the fish is best served fresh. This makes it ideal for batch cooking: prepare sauce components separately and assemble when ready to eat.
The shrimp adds sodium, so reduce added salt if you're monitoring intake. For extra nutrition, serve with steamed broccoli or quinoa to round out the meal. ✨

Frequently asked questions
Can I substitute shrimp in the sauce with another protein?
Yes! For a similar texture, use scallops or chopped white fish fillets (like cod or tilapia). If you prefer a different flavor, chicken breast works too—just reduce cooking time to 3-4 minutes to avoid drying out. For a vegetarian version, try mushrooms or tofu, but the sauce will have a slightly different mouthfeel.
Why is my shrimp sauce too thin or too thick?
If the sauce is too thin, simmer uncovered for 2-3 extra minutes to reduce it. For thickening, mix 1 tsp cornstarch with 1 tbsp water and stir in at the end. Too thick? Thin with 1 tbsp warm water or milk. The ideal consistency should coat the back of a spoon but still pour smoothly over the fish.
How do I keep the fish from drying out?
Don't overcook! Bake until the fish reaches 145°F (about 12-15 minutes at 375°F), and resist peeking at it. For extra moisture, add a lemon slice or butter pat to the baking sheet. If using thicker fillets, reduce oven temp to 350°F and bake for 18-20 minutes.
Can I make this recipe ahead of time?
The sauce can be made 2-3 days ahead and stored in an airtight container. Reheat gently in a saucepan with 1 tbsp water to restore thickness. The fish is best baked fresh, but you can prep it up to 12 hours ahead—just pat dry before baking and add 3-5 minutes to the cooking time if cold.
What are the best sides to serve with this dish?
For a complete meal, pair with buttery mashed potatoes, steamed asparagus, or a simple green salad. The creamy sauce also works beautifully with wild rice or roasted Brussels sprouts. For extra flair, add a crusty baguette to soak up any leftover sauce.
