Whole cauliflower baked to perfection with butter, Parmesan cheese, and a creamy mustard-mayo topping—an easy, savory dish that transforms a simple vegetable into a showstopping side.
Place the whole cauliflower head in a steamer basket over boiling water. Cover and steam for approximately 30 minutes, or until the cauliflower is fork-tender but still holds its shape. Remove from heat, drain, and allow to cool slightly.
Prepare for Baking:
Preheat the oven to 375°F (190°C). Transfer the steamed cauliflower to a baking dish or pie plate.
Mix the Topping:
In a small bowl, combine the mayonnaise and mustard until smooth. Using a spoon or brush, evenly coat the top and sides of the cauliflower with the mixture.
Add Butter and Cheese:
Dot the surface of the cauliflower with the butter pieces. Generously sprinkle the Parmesan cheese over the entire head, ensuring it covers the top and sides.
Bake:
Place the cauliflower in the preheated oven and bake uncovered for approximately 30 minutes, or until the cheese is golden brown and slightly crisp. Allow to cool briefly before slicing and serving.
Notes
This recipe is naturally gluten-free as written. However, for added assurance:
Double-check that the mustard and mayonnaise brands used are certified gluten-free, as some processed condiments may contain trace amounts of gluten due to additives or cross-contamination.
Use freshly grated Parmesan cheese rather than pre-shredded varieties, which can sometimes include anti-caking agents containing gluten.
