Ingredients

Equipment

• Large pot (for boiling cauliflower)
• Colander
• Large sauté pan or skillet
• Mixing bowl
• Spatula or wooden spoon
• 8×8-inch baking dish (glass or ceramic)
• Cheese grater (if grating cheese fresh)
• Oven

Instructions

1. Prep the cauliflower:

   Cut the cauliflower into bite-sized florets. Bring a large pot of salted water to a boil, add the cauliflower, and cook for 5–7 minutes, until just fork-tender.

   Drain well and set aside.

2. Sauté the aromatics and spinach:

   In a large skillet, melt the butter over medium heat. Add the onion and cook for 2–3 minutes until translucent.

   Stir in the minced garlic and cook for 30 seconds more. Add the fresh spinach and cook until wilted, about 2–3 minutes.

   Remove from heat.

3. Make the cheese sauce:

   In a medium bowl, combine the cream cheese and heavy cream. Microwave for 30–45 seconds to soften (or heat gently in a pan).

   Whisk until smooth. Stir in the shredded mozzarella, cheddar, salt, black pepper, Italian herbs, and red pepper flakes.

   Mix until well combined.

4. Combine the veggies and sauce:

   Add the cooked cauliflower and sautéed spinach mixture to the cheese sauce. Gently fold everything together until the veggies are coated evenly.

5. Assemble the bake:

   Transfer the mixture to a greased 8×8-inch baking dish. Sprinkle the grated parmesan evenly over the top for a cheesy crust.

6. Bake:

   Preheat your oven to 375°F (190°C). Bake the dish uncovered for 20–25 minutes, or until the top is golden and bubbly.

7. Cool and serve:

   Let the bake cool for 5–10 minutes before serving. Slice into portions and enjoy!

Tips & Variations

• Tip: For an extra-crispy top, broil the casserole for 2–3 minutes at the end of baking. Watch closely to avoid burning!

• Make it spicy: Add more red pepper flakes, or stir in a diced jalapeño with the onion.
• Change the greens: Substitute kale, Swiss chard, or even arugula for spinach, depending on what’s in your fridge.
• Try different cheeses: Smoked gouda or pepper jack can bring a new flavor dimension.
• Add protein: Toss in some chopped, cooked eggs, or serve alongside a veggie egg bite for extra satisfaction.
• Bulk it up: Stir in steamed broccoli, zucchini, or mushrooms—just be sure to drain any excess moisture first.
• Oven-free version: Prepare everything in a skillet and finish under the broiler if you want to skip baking.

• “Don’t be afraid to use frozen cauliflower or spinach! Just thaw and drain well to avoid a watery casserole.”

• For a nutty crunch, sprinkle chopped walnuts or almond flour on top before baking.
