Cheesy Winter Squash Casserole

Step 1

Butter an 8-inch (1.5 L) baking dish and preheat oven to 350°F (180°C). 

Step 2

In a large skillet, melt butter over medium heat. Add squash, onion, garlic, salt and pepper. Cover and cook, stirring often for 8 minutes or until squash is softened slightly.

Step 3

Béchamel Sauce: In a saucepan, melt butter over medium heat. Stir in flour and thyme; cook, stirring for 1 minute. Gradually whisk in milk until combined. Cook, whisking for about 8 minutes or until thickened enough to coat back of spoon; stir in nutmeg and salt. Remove from heat.

Step 4

Spoon 1/3 of the squash mixture onto the bottom of the 8-inch (1.5 L) baking dish. Spread 1/3 of the béchamel and cheese over top. Repeat layers twice. Bake for about 50 minutes or until top is golden and bubbly. Let stand 10 minutes before serving.
