INGREDIENTS 

 

FOR THE CASSEROLE

4–5 yellow squash, sliced

1 small onion, diced

2 Tbsp butter or oil

Salt and black pepper, to taste

 

 

FOR THE ROUX CREAM BASE

3 Tbsp butter

3 Tbsp all-purpose flour

1 cup evaporated milk

1/2 cup chicken stock

1/2 tsp garlic powder

1/2 tsp onion powder

1 tsp fresh rosemary, finely chopped

Optional pinch cayenne

Salt and black pepper, to taste

 

FOR THE TOPPING

1/2–1 cup breadcrumbs, panko, or crushed crackers

1–2 Tbsp butter, melted

Optional 1/4 cup mild shredded cheese

 

 

INSTRUCTIONS

1. Cook the Squash

Sauté squash and onion in butter or oil for 8–10 minutes until tender. Season lightly with salt and black pepper. Drain all liquid released by the squash to prevent a watery casserole.

2. Make the Mild Blond Roux

Melt butter in a saucepan over medium heat. Whisk in flour and cook 3–4 minutes until blond, not brown. Slowly whisk in evaporated milk, then chicken stock. Add garlic powder, onion powder, rosemary, optional cayenne, salt, and black pepper. Simmer until thick enough to coat a spoon.

3. Combine

Stir the drained squash mixture into the thickened roux base. Taste and adjust seasoning as needed.

4. Prepare the Topping

Mix breadcrumbs with melted butter. Add shredded cheese if using.

5. Bake

Preheat oven to 350°F. Transfer squash mixture to a greased casserole dish and top evenly. Bake 20–25 minutes until bubbly and golden.

6. Serve

Serve warm as a side dish with poultry, pork chops, ham, seafood, or holiday meals.
