Ingredients You’ll Need
For the Cauliflower Base:

- 2 tbsp butter or ghee (or coconut oil for vegan option)
- Salt and pepper to taste
Tip: Use pre-steamed cauliflower rice for faster prep!
For the Cheesy Jalapeño Mixture:
- 8 oz cream cheese, softened
- 1/2 cup sour cream or full-fat Greek yogurt
- 1/2 cup chopped jalapeños (fresh or canned)
- 1/2 tsp garlic powder
- 1/2 tsp smoked paprika
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 cup shredded mozzarella or cheddar cheese
Optional: Add 1/4 cup cooked crumbled bacon for smoky contrast
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) . Grease a 9×9-inch baking dish or line with parchment paper for easy removal.
Pro Tip: Use a cast iron skillet for even browning and rustic presentation.
Step 2: Prepare the Cauliflower
If using frozen cauliflower rice, steam or sauté until tender (about 5–6 minutes ).
If using fresh, microwave or sauté until just softened.
Season lightly with salt and pepper.
Set aside to cool slightly before mixing.
Step 3: Mix the Jalapeño Cheese Filling
In a large bowl, beat softened cream cheese until smooth.
Add sour cream or Greek yogurt, jalapeños, garlic powder, smoked paprika, salt, and pepper.
Mix well until fully incorporated.
Fold in half of the shredded cheese.
Pro Tip: For best results, use room temperature dairy to avoid lumps.
Step 4: Combine and Layer
In the prepared baking dish:
- Spread half of the cauliflower evenly across the bottom.
- Pour half of the cheese mixture over the top and spread gently.
- Repeat layers: remaining cauliflower, then remaining cheese mixture.
Sprinkle the top generously with remaining mozzarella or cheddar cheese.
Optional: Top with sliced jalapeños for extra visual appeal and heat.
Step 5: Bake Until Golden and Bubbly
Transfer to the preheated oven and bake for 25–30 minutes , or until golden brown and bubbly around the edges.
Turn on the broiler for the last 2–3 minutes for extra browning.
Let sit for 5–10 minutes before serving to allow better slicing.
Step 6: Serve and Enjoy!
Serve warm straight from the pan or transfer to plates.
Pair with:
- A dollop of sour cream or guacamole
- Chopped cilantro or lime wedges
