How to Make Cauliflower Pastelón
Step 1: Prepare the Beef Filling
Heat a large skillet over medium heat. Add chopped onions and cook until soft and translucent. Stir in minced garlic and cook for 1 minute until fragrant. Add bell peppers and cook for another 2–3 minutes.
Add ground beef and cook until browned, breaking it apart as it cooks. Season with salt, adobo-style spices, and sazón if available. Stir in crushed tomatoes and let simmer for 8–10 minutes until thick and flavorful. Set aside.
Step 2: Make the Cauliflower Mash
Cut cauliflower into florets and steam until very soft (about 20–30 minutes). This is crucial for a smooth texture.
Drain completely — removing all excess water is key to avoid a watery casserole.
Transfer to a bowl and add butter, heavy cream, parmesan cheese, salt, garlic powder, and pepper. Blend until smooth using an immersion blender or food processor.
Once slightly cooled, mix in egg yolks to create a rich, stable mash.
Step 3: Assemble the Layers
Preheat oven to 350°F (175°C). Grease a baking dish.
Layer in this order:
- Half of the cauliflower mash
- A layer of shredded cheese
- All of the beef filling
- Another light layer of cheese
- Remaining cauliflower mash
- Top with remaining mozzarella and cheddar
Step 4: Bake to Perfection
Bake uncovered for 30–35 minutes until hot and bubbly.
For a golden, crispy top, broil for 2–3 minutes at the end.
Step 5: Rest Before Serving
Let the pastelón rest for at least 30 minutes before slicing. This step is crucial for clean layers and structure.
