Jump to Recipe Print Recipe

If you love the bold, indulgent flavors of jalapeño poppers but want something lighter, healthier, or keto-friendly, jalapeño popper cauliflower casserole is the answer. This dish delivers everything you crave—cream cheese, melted cheddar, smoky bacon, and spicy jalapeños—wrapped around tender roasted cauliflower instead of breaded peppers.

The result is a rich, satisfying casserole that feels indulgent but fits beautifully into low-carb and keto lifestyles. It works just as well as a hearty side dish as it does a vegetarian-friendly main, and it’s guaranteed to win over even the most skeptical cauliflower eaters.

This recipe transforms humble cauliflower into something bold, creamy, and completely irresistible.

Why Cauliflower Is the Perfect Base

Cauliflower is a blank canvas that absorbs flavor beautifully. When roasted or baked properly, it becomes tender without turning mushy, making it ideal for creamy casseroles.

This casserole works because:

  • Cauliflower provides structure without carbs
  • Cream cheese creates richness and body
  • Jalapeños add heat and brightness
  • Bacon adds smoky depth
  • Cheese ties everything together

It’s comfort food that doesn’t feel heavy or starchy.
