How To Make Cheesy PEI Lobster Potato Bake

Step 1: Prepare The Cheese Sauce

Preheat oven to 375°F.

In a saucepan melt butter over medium heat.

Whisk in flour and cook for 1 minute.

Slowly whisk in milk and cream.

Cook until thickened.

Add shredded cheddar cheese and stir until smooth.

Season with garlic powder, salt, and pepper.

Step 2: Layer The Potatoes

Grease a large casserole dish.

Arrange half the sliced potatoes in an even layer.

Pour over half of the cheese sauce.

Repeat with remaining potatoes and sauce.

Step 3: Bake

Cover with foil.

Bake for 45 minutes until potatoes are nearly tender.

Step 4: Add The Lobster

Remove the foil.

Scatter lobster meat and green onions evenly across the top.

Step 5: Add The Topping

Combine breadcrumbs, melted butter, parsley, and chives.

Sprinkle evenly over the casserole.

Step 6: Finish Baking

Return to the oven and bake for an additional 20 minutes.

Tips For The Best Lobster Potato Bake

Use Freshly Shredded Cheese

Freshly shredded cheddar melts more smoothly than pre-packaged cheese.

Don’t Overcook The Lobster

Since the lobster is already cooked, it only needs to warm through during the final bake.

Slice Potatoes Thinly

Thin slices help ensure the potatoes cook evenly and absorb the creamy cheese sauce.

Let It Rest Before Serving

Allowing the casserole to rest helps the sauce thicken and makes serving easier.
