How to Make Creamy Low-Carb Seafood Bake
-
Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish lightly to prevent sticking and help the dish cook evenly.
-
Pat dry the shrimp and scallops with paper towels. Sprinkle lightly with salt and garlic powder to season them nicely.
-
Sear the scallops in a large skillet with olive oil over medium-high heat for 1–2 minutes per side until lightly golden. Remove them and set aside. Add the shrimp and cook for about 1 minute per side, just until they start to turn pink. Remove from the skillet.
-
Cook diced onion and sliced mushrooms in the same skillet with melted butter over medium heat. Stir for 5–6 minutes until softened and the moisture evaporates.
-
Add garlic and cook for 30 seconds to release its aroma. Then, toss in the baby spinach and cook for another 1–2 minutes until it wilts down.
-
Mix in the heavy cream, softened cream cheese, Parmesan, onion powder, and lemon juice. Stir constantly for 3–4 minutes until the sauce becomes smooth and creamy.
-
Fold the cooked shrimp and scallops gently into the creamy spinach and mushroom mixture, ensuring they’re fully coated.
-
Spoon the seafood mixture into the prepared baking dish, spreading it out evenly for consistent cooking.
-
Sprinkle the shredded mozzarella generously over the top, making sure every part is covered for that beautiful cheesy melt.
-
Bake uncovered for 12–18 minutes until the cheese is bubbly and golden, and the seafood reaches an internal temperature of 145°F (63°C).
-
Broil for 1–2 minutes if you like a lightly browned cheese topping, but keep a close eye to prevent burning.
-
Garnish with fresh parsley after removing from the oven and let it rest for 3–5 minutes before diving in for the best flavor!
Optional: Serve with a slice of lemon on the side for an extra zing.

Creamy Low-Carb Seafood Bake with Shrimp, Scallops, Spinach and Mushrooms Recipe FAQs
How do I select the best seafood for this recipe?
Absolutely! When choosing shrimp and scallops, look for fresh seafood that’s translucent and firm. The shrimp should have a sweet aroma, and the scallops should be creamy white with no dark spots. If you’re opting for frozen seafood, ensure it’s fully thawed before cooking to get the best texture.
How should I store leftovers from this casserole?
Very good question! Store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy them again, simply reheat in the oven at 350°F (175°C) for about 15–20 minutes or until heated throughout. This method helps maintain the lovely creamy texture.
Can I freeze the Creamy Low-Carb Seafood Bake?
Certainly! To freeze, assemble the casserole without baking and use an airtight container for storage. It can be frozen for up to 2 months. When ready to bake, thaw overnight in the fridge, then follow baking instructions at 375°F (190°C). Sprinkle the mozzarella cheese just before baking for a fresh touch!
What should I do if my seafood becomes rubbery while cooking?
Great question! To prevent rubbery seafood, avoid overcooking. Start by searing the shrimp and scallops for just 1–2 minutes; they should still be slightly undercooked when removed from the skillet. They’ll finish cooking in the oven and maintain that tender, buttery texture you’re aiming for.
Are there any dietary considerations for this recipe?
Yes! This dish is low-carb but be aware of shellfish allergies as both shrimp and scallops are common allergens. For a gluten-free adaptation, ensure that no additional ingredients contain gluten. If you’re serving this to others, letting them know about the seafood and dairy content is a good idea.
What alternative vegetables might work well in the casserole?
The more the merrier! You can absolutely customize this dish by including bell peppers, zucchini, or even artichoke hearts for variety. Sauté these along with the onions and mushrooms to blend flavors beautifully. This not only adds nutrients but enhances the visual appeal of your creamy low-carb seafood bake.
