How to Make Cheesy Baked Cauliflower

Step-by-Step Instructions

1. Preheat and prep:
Preheat your oven to 400°F (200°C). Lightly grease your baking dish.

2. Cook the cauliflower:
Bring a large pot of salted water to a boil. Add the cauliflower florets and cook for 5 minutes until just tender. Drain well and set aside.

3. Make the cheese sauce:
In a saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until bubbly. Gradually whisk in the milk, stirring constantly, until the sauce thickens (about 5 minutes). Stir in the mustard, garlic powder, paprika, salt, and pepper.

4. Add the cheese:
Remove from heat and stir in 1 cup of cheddar cheese and all of the Parmesan until melted and smooth.

5. Combine:
Place the cauliflower in your prepared baking dish. Pour the cheese sauce over and gently stir to coat evenly.

6. Top and bake:
Sprinkle the remaining ½ cup cheddar over the top. Bake for 20-25 minutes or until golden and bubbly.

7. Garnish and serve:
Let cool slightly, then sprinkle with parsley and serve warm!

What to Serve With Cheesy Baked Cauliflower

This side pairs perfectly with:

Grilled chicken or pork chops
Baked salmon
Veggie burgers or lentil loaf
A fresh green salad or roasted Brussels sprouts

Or let it shine as a main dish—just add a hearty green salad and crusty bread!

Tips for the Best Baked Cauliflower

Don’t overcook the cauliflower: Boil just until fork-tender, not mushy.
Drain well: Extra water will make your casserole watery.
Shred your own cheese: Pre-shredded cheese doesn’t melt as smoothly.
Let it rest before serving: Gives the cheese sauce time to set a little.

Storage Instructions

Refrigerate: Store leftovers in an airtight container for up to 4 days.
Reheat: Warm in a 350°F oven or microwave until heated through.
Freeze: You can freeze before baking—just thaw overnight before baking.
