Ingredients

1 large head of cauliflower (about 2.5 lbs), cut into florets
1 tablespoon olive oil
½ teaspoon sea salt
½ teaspoon black pepper
8 oz cream cheese, softened
½ cup sour cream
¼ cup mayonnaise
1 and ½ cups shredded sharp cheddar cheese, divided
½ cup shredded mozzarella cheese
3 medium jalapeno peppers, seeded and finely chopped (plus extra for garnish, optional)
6 slices bacon, cooked crisp and crumbled, divided
2 green onions, sliced (for garnish, optional)

Directions

Step 1: Prep and Roast the Cauliflower

Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper.
In a big mixing bowl, toss cauliflower florets with olive oil, salt, and pepper.
Spread cauliflower evenly on the prepared baking sheet. Roast for 20 minutes until golden and tender, flipping halfway.

Step 2: Make the Creamy Cheese Mixture

In a large bowl, combine softened cream cheese, sour cream, and mayonnaise. Mix until smooth.
Add 1 cup cheddar cheese, mozzarella cheese, chopped jalapenos, and half of the crumbled bacon. Stir until evenly combined.

Step 3: Assemble the Casserole

Lower oven temperature to 375°F (190°C). Grease a 9x13-inch baking dish with nonstick spray.
Gently fold roasted cauliflower into the cheese mixture. Spread evenly in the prepared casserole dish.
Top with remaining ½ cup cheddar cheese and the rest of the bacon.

Step 4: Bake and Serve

Bake uncovered for 20-25 minutes, until bubbly and cheese is melted and golden on top.
Remove from oven and let rest for 5 minutes. Garnish with sliced green onions and extra jalapeno rings if desired before serving.

Notes

For extra creamy texture, make sure your cream cheese is fully softened before mixing.
If you prefer less heat, remove all seeds and membranes from the jalapenos (or use less).
You can prep and roast the cauliflower a day ahead to save time on busy nights.

Shred your own cheese for gooier, meltier results instead of pre-shredded blends.
Let casserole rest before serving so it sets and slices neatly.

FAQ

Can I make this casserole ahead of time?

Yes! Assemble everything up to the baking step, cover, and refrigerate for up to 24 hours. Bake right before serving.

How spicy is this casserole?

The spice level depends on how many jalapenos you use and whether you remove the seeds. For mild heat, use fewer jalapenos and take out all seeds.

Can I freeze leftovers?

Freezing is not recommended, as the creamy cheese sauce may separate when thawed. It's best enjoyed fresh or refrigerated for a few days.
