Tasty Jalapeno Popper Cauliflower Casserole Recipe
Introduction
This Tasty Jalapeno Popper Cauliflower Casserole is a flavorful, cheesy dish that combines the heat of jalapenos with creamy cheese and crispy bacon. It’s a perfect low-carb side or a satisfying vegetarian-friendly main when you skip the bacon. Easy to prepare and sure to please any crowd!

Ingredients
- 3 jalapenos (seeded and diced into 1/4-inch pieces)
- 1 head cauliflower (cut into bite-sized florets)
- 2 tbsp cream cheese (softened to room temperature)
- 1 tsp salt
- 1/2 tsp black pepper (freshly ground for best flavor)
- 3/4 cup shredded cheddar cheese (I use Tillamook sharp cheddar)
- 4 slices cooked bacon (crumbled into small bits)
Instructions
- Step 1: Preheat your oven to 400 degrees F (205 degrees C). Spread the cauliflower evenly on a baking sheet and roast for 15 minutes. This will soften the cauliflower and enhance its natural flavors.
- Step 2: Remove the cauliflower from the oven and reduce the temperature to 375 degrees F (190 degrees C) to prepare for baking the casserole.
- Step 3: Transfer the roasted cauliflower into a mixing bowl. Add the cream cheese, salt, and pepper, then stir well to coat the cauliflower evenly with the seasoned cream cheese.
- Step 4: Pour the cauliflower mixture into a baking dish. Evenly scatter the diced jalapenos and crumbled bacon over the top. Then sprinkle the shredded cheddar cheese across the surface for a rich, cheesy crust.
- Step 5: Bake the casserole at 375 degrees F (190 degrees C) for 15 minutes, until the cheese is melted and bubbling but not browned. Let it cool slightly before serving.
Tips & Variations
- Use smoked paprika or garlic powder in the cauliflower mixture for an extra depth of flavor.
- For a vegetarian version, omit the bacon and add sautéed mushrooms or extra cheese instead.
- If you like it spicier, leave some jalapeno seeds in or add a dash of hot sauce before baking.
- Make sure the cream cheese is softened to avoid lumps and ensure a smooth coating.
Storage
Store leftover casserole covered in the refrigerator for up to 3 days. Reheat in the oven at 350 degrees F (175 degrees C) until warmed through, or microwave individual portions for about 1-2 minutes. Best enjoyed fresh but still delicious when reheated.

FAQs
Can I make this casserole ahead of time?
Yes, you can assemble the casserole and refrigerate it before baking. Just cover it tightly and bake within 24 hours, adding a few extra minutes to the baking time if baking straight from the fridge.
What can I use instead of cream cheese?
You can substitute cream cheese with sour cream or Greek yogurt for a lighter option, though the texture will be slightly different. Soft goat cheese can also add a unique flavor twist.

- 1 head cauliflower (cut into bite-sized florets)
Dairy
- 2 tbsp cream cheese (softened to room temperature)
- 3/4 cup shredded cheddar cheese (Tillamook sharp cheddar preferred)
Meat
- 4 slices cooked bacon (crumbled into small bits)
Seasonings
- 1 tsp salt
- 1/2 tsp black pepper (freshly ground for best flavor)
Instructions
- Preheat and Roast the Cauliflower: Preheat your oven to 400°F (205°C). Spread the bite-sized cauliflower florets evenly on a baking sheet and roast them for 15 minutes. This step softens the cauliflower and enhances its natural flavors.
- Reduce Oven Temperature: After roasting, remove the cauliflower from the oven and lower the oven temperature to 375°F (190°C) to prepare for the casserole’s final bake.
- Prepare the Cauliflower Mixture: Transfer the roasted cauliflower into a mixing bowl. Add softened cream cheese, salt, and freshly ground black pepper. Stir thoroughly to coat the cauliflower evenly with the creamy seasoning.
- Assemble the Casserole: Pour the cauliflower and cream cheese mixture into a baking dish. Evenly sprinkle diced jalapenos and crumbled cooked bacon over the top. Finish by spreading a generous layer of shredded cheddar cheese over everything to create a cheesy crust.
- Bake the Casserole: Place the dish in the oven and bake for an additional 15 minutes at 375°F (190°C). Bake until the cheese is bubbly and melted but not browned. Once done, remove the casserole and let it cool slightly before serving.
Notes
- For a milder dish, reduce the amount of jalapenos or omit the seeds.
- Use thick-cut bacon for extra smoky flavor and a better texture contrast.
- You can prepare the casserole up to the assembly step, then refrigerate it for a few hours before baking.
- Substitute cheddar with Monterey Jack or Pepper Jack for a different cheese twist.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
