Ingredients

Why this recipe works

The slow cooker's gentle, steady heat is ideal for seafood. It cooks the lobster and shrimp slowly, keeping them moist and tender instead of rubbery.

The butter and wine create a natural basting liquid that infuses the seafood and vegetables with rich flavor as they simmer.

Layering the ingredients in the order shown ensures even cooking. The seafood sits at the bottom where it's closest to the heat, while the denser potatoes and corn cook alongside. The butter melts over everything, so each component absorbs the herb and garlic essence.

Notes and substitutions

Use split cold-water lobster tails for the best texture and flavor. If you can't find them, whole lobster tails can be split with kitchen shears. For the shrimp, choose raw jumbo shrimp that are peeled and deveined—they'll cook quickly and stay juicy.

The parsley-garlic scampi butter is what makes this dish sing. You can buy it pre-made or make your own by mixing softened butter with minced garlic, chopped parsley, and a pinch of salt. The white wine adds brightness and depth; choose a dry wine you'd enjoy drinking.

• parsley-garlic scampi butter: Use 6 tablespoons unsalted butter mixed with 2 cloves minced garlic and 2 tablespoons chopped fresh parsley.
• dry white wine: Substitute with seafood stock or chicken broth for a non-alcoholic version.
• baby red bliss potatoes: Use Yukon Gold or new potatoes, cut into halves or quarters if large.
• jumbo shrimp: Large shrimp work well; adjust cooking time slightly if smaller.
