Ingredients
- Kosher salt

- 2 tbsp. unsalted butter, divided
- 1/2 lb. medium shrimp, peeled, deveined
- 1/2 lb. scallops, side muscle removed, patted dry
- Freshly ground black pepper
- 1 small shallot, finely chopped
- 3 garlic cloves, finely chopped
- 1 c. finely chopped tomatoes
- 3/4 c. low-sodium chicken or vegetable broth
- 3/4 c. heavy cream
- 1/2 c. finely grated Parmesan, plus more for serving
- 1/4 c. finely chopped fresh parsley, plus more for serving
- 1/2 lemon, juiced
Instructions
- Step 1: In a large pot of boiling salted water, cook spaghetti, stirring occasionally, until al dente according to package directions. Drain and return to pot.
- Step 2: Meanwhile, in a large skillet over medium heat, melt 1 tablespoon of butter. Add shrimp and season with salt and pepper. Cook, turning halfway through, until shrimp are opaque, about 2 minutes per side. Transfer to a plate.
- Step 3: In the same skillet over medium heat, melt the remaining 1 tablespoon of butter. Add scallops and season with salt and pepper. Cook, turning halfway through, until browned on both sides, about 2 minutes per side. Transfer to the same plate with shrimp.
- Step 4: In the same skillet over medium heat, cook shallot and garlic, stirring, until softened and fragrant, about 3 minutes. Add tomatoes, broth, cream, Parmesan, and parsley; season with salt. Bring to a simmer and cook, stirring occasionally, until slightly thickened, about 3 minutes.
- Step 5: Return shrimp and scallops to skillet and toss to combine. Stir in lemon juice. Add cooked spaghetti and toss until coated with the sauce.
- Step 6: Divide pasta among plates or shallow bowls. Top with more Parmesan and parsley before serving.
Tips & Variations
- For extra depth, add a splash of white wine to the sauce before adding the broth and cream.
- Substitute scallops with firm white fish fillets if preferred.
- Use fresh tomatoes in season for a brighter flavor instead of canned.
- Garnish with a pinch of red pepper flakes for a subtle heat.
Storage
Store leftover seafood spaghetti in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stovetop over low heat, adding a splash of broth or water to loosen the sauce. Seafood can become tough if overcooked during reheating, so warm it briefly or serve cold as a pasta salad alternative.

Notes
- Use low-sodium broth to control the saltiness of the dish.
- Pat scallops dry to ensure they sear properly and develop a nice crust.
- Serve immediately for best texture, as seafood can become rubbery if overcooked or reheated.
- Fresh parsley and lemon juice brighten the rich cream sauce.
- Can substitute heavy cream with half-and-half for a lighter sauce, though it may be less rich.
