In a large skillet, saute onion and garlic in oil and 2 tablespoons butter until tender.
Stir in broth and clam juice; bring to a boil.
Add the scallops, shrimp, crab and 1/8 teaspoon pepper; return to a boil.
Reduce heat; simmer, uncovered, for 4-5 minutes or until shrimp turn pink and scallops are firm and opaque, stirring gently.
Drain, reserving cooking liquid; set seafood mixture aside.
In a large saucepan, melt the remaining butter; stir in flour until smooth and make a light brown roux.
Combine milk and reserved cooking liquid; gradually add to the saucepan. Add salt, garlic powder, old bay seasoning and remaining pepper. Bring to a boil; cook and stir for 2 minutes or until thickened. Remove from the heat; stir in cream and 1 cup Parmesan cheese. ****
Add seafood back to the saucepan and add any additional seasoning to your taste preference.
Spoon over cooked noodles, over veggies, over steak… and enjoy!
