1. Preheat oven to 400°F (200°C).

2. In a large oven-safe skillet, melt butter over medium heat. Add diced onion and garlic; sauté until softened.

3. Sprinkle flour over the onions and stir for 1 minute to cook off the raw taste.

4. Slowly whisk in broth and cream. Simmer until thickened.

5. Add Old Bay seasoning, peas and carrots, shrimp, and scallops. Simmer for 3–4 minutes, just until seafood is slightly opaque. Remove from heat.

6. In a mixing bowl, combine Cheddar Bay biscuit mix, shredded cheddar, and milk until just combined.

7. Use a scoop to drop biscuit dough evenly over the seafood mixture.

8. Bake for 18–22 minutes, or until biscuits are golden and filling is bubbling.

9. Sprinkle with fresh parsley. Let rest 5 minutes before serving.
