Food History

Cauliflower has been part of culinary traditions worldwide due to its versatility and health benefits. It became trendy in Western cuisine as a low-carb alternative in various dishes, including casseroles. Combining cauliflower with a white sauce is a classic approach in French and Italian cooking, often used to enhance the vegetable’s mild flavor.


  • 1600s: Introduction of cauliflower to France from Italy.
  • 1700s: Cauliflower becomes popular in northern Europe.
  • 20th century: Cauliflower recipes proliferate in American and European cookbooks, often featuring béchamel (white sauce) and cheese.
  • Today: Cauliflower is celebrated for its versatility in recipes from simple steamed sides to complex casseroles and as a substitute in low-carb diets.

Recipe Discussion

This Cauliflower Casserole recipe incorporates lightly boiled cauliflower florets, ensuring they retain a slight crunch which contrasts beautifully with the creamy sauce. The sautéed onions provide a sweet and savory base, enhancing the dish’s overall flavor. The white sauce, enriched with a bit of tomato sauce, offers a subtle tanginess that complements the mild taste of cauliflower, while the cheese topping adds a deliciously gooey texture.

Serving Suggestions

Serve this Cauliflower Casserole as a main dish with a side of crusty bread or as a side dish alongside grilled or roasted meats. It pairs well with a light, crisp salad to balance the richness of the cheese and white sauce.

Preparation Tips

To enhance the flavor, roast the cauliflower instead of boiling it for a deeper, nuttier taste. When making the white sauce, use low heat to avoid clumping and stir continuously for a smooth texture. Adding a pinch of nutmeg to the sauce can also introduce a subtle warmth that complements the tomato sauce beautifully.
