Food History
Casseroles have been a staple in American cuisine for decades, evolving from simple, one-dish meals to more sophisticated combinations of vegetables, meats, and sauces. This particular recipe blends two cold-weather vegetables—brussels sprouts and winter squash—which have been popular for centuries in European and American cooking.
Brussels sprouts, believed to have originated in Belgium (hence their name), have been cultivated since the 13th century. They were brought to America in the 18th century and have since become a common vegetable, particularly in fall and winter recipes. With its roots in the Americas, winter squash was a staple crop for indigenous communities long before it was introduced to European settlers. Both of these vegetables are celebrated for their nutritional benefits and ability to withstand cold temperatures, making them ideal for seasonal dishes.

Recipe Discussion
This Brussels Sprouts and Squash Casserole is closest to a vegetable gratin, where vegetables are layered and baked in a creamy sauce. The brussels sprouts add an earthy flavor, while the winter squash provides a natural sweetness. The casserole is then brought together with a creamy sauce that’s seasoned with marjoram, nutmeg, and a hint of pepper for depth and warmth.
- Brussels Sprouts: These are cleaned, trimmed, and steamed until tender but still slightly firm, allowing them to hold their shape and texture in the casserole.
- Winter Squash: The squash is peeled, cubed, and steamed separately from the sprouts. The squash’s natural sweetness balances the sprouts’ slight bitterness.
- Onion and Celery: These aromatic vegetables are sautéed in butter and oil, forming the base of the sauce and adding depth to the flavor.
- Creamy Sauce: The sauce is thickened with whole-wheat flour, giving it a slightly nutty flavor. Milk or soy milk can be used to make the dish creamier or dairy-free, depending on your preference.
- Seasonings: Marjoram, nutmeg, salt, and pepper add subtle flavors that complement the vegetables. Nutmeg is especially effective in enhancing the creaminess of the sauce.

Preparation Tips
- Scoring Brussels Sprouts: Scoring the base of each brussels sprout (cutting a small “X” into the stem) ensures they cook evenly when steamed.
- Steaming the Vegetables: Steam the brussels sprouts and squash separately until they are barely tender, as they will continue cooking in the oven.
- Using Whole-Wheat Flour: Whole-wheat flour adds a nutty flavor and more nutrients, but all-purpose flour can be substituted if preferred.
- Adjusting for Dairy-Free: To make the casserole dairy-free, use a plant-based butter and soy milk instead of regular milk.
- Layering for Even Cooking: Arrange the squash cubes on the bottom of the baking dish and layer the brussels sprouts and celery evenly on top for even cooking and flavor distribution.
