Instructions

Preheat Oven:
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Blanch Broccoli:
Bring a pot of salted water to a boil. Add broccoli and cook 2–3 minutes until bright green and slightly tender. Drain and set aside.
Cook Spinach:
In a skillet over medium heat, sauté spinach for 1–2 minutes until wilted. Remove from heat and squeeze out excess moisture.
Make Cheese Sauce:
In a saucepan, melt butter over medium heat. Whisk in flour and cook 1–2 minutes. Gradually whisk in milk and cream. Cook until thickened (about 3–4 minutes).
Stir in garlic powder, onion powder, salt, pepper, and nutmeg. Add ½ cup cheddar and mozzarella; stir until melted and smooth.
Combine:
In a large bowl, mix broccoli, spinach, and cheese sauce until evenly coated.
Assemble:
Transfer mixture to prepared baking dish. Top with remaining cheddar and Parmesan cheese. Sprinkle breadcrumbs if using.
Bake:
Bake uncovered for 15–20 minutes until bubbly and golden on top.
Rest & Serve:
Let sit for 5 minutes before serving.

Notes

📝 Notes

Use fresh or frozen broccoli and spinach; drain well to avoid watery casserole.
Mix cream cheese, sour cream, and shredded cheddar for a rich, creamy base.
Add garlic powder, onion powder, or nutmeg for extra depth of flavor.
Top with breadcrumbs or extra cheese for a crispy golden finish.
Pre-cook broccoli slightly to ensure even tenderness in the casserole.
Season carefully; cheese already adds saltiness.
Let the casserole rest 5–10 minutes before serving to set.
Store leftovers in an airtight container in the fridge for up to 3 days; reheat gently.
