4.5 from 113 reviews

A delicious and creamy Keto Cheesy Spinach Broccoli Casserole that combines tender broccoli and fresh spinach with a blend of sharp cheddar, mozzarella, and cream cheese for a low-carb, satisfying side dish or main course.

Ingredients

Scale

Vegetables

  • 1 clove of garlic, crushed
  • 12 ounce package of frozen broccoli florets (approx 4 cups)
  • 2 cups fresh spinach

Dairy & Condiments

  • 2 tablespoons mayonnaise
  • 2 ounces cream cheese
  • 1/2 cup sharp cheddar cheese, shredded
  • 3/4 cup mozzarella cheese, shredded

Spices

  • 1/2 teaspoon onion powder

Instructions

  1. Preheat Oven: Preheat your oven to 350°F to prepare for baking the casserole.
  2. Cook Broccoli: Cook the frozen broccoli according to the package instructions. If using fresh broccoli, chop and microwave it for about 5 minutes until tender. Drain thoroughly.
  3. Mix Ingredients: In a large mixing bowl, combine the hot broccoli with cream cheese, mayonnaise, crushed garlic, onion powder, and fresh spinach. Stir well to incorporate all ingredients. The heat from the broccoli will help melt the cheeses and wilt the spinach. Season with salt and black pepper if desired, though the cheese provides enough saltiness.
  4. Prepare Baking Dish: Spray a baking dish with nonstick cooking spray. Spread the broccoli and spinach mixture evenly in the dish.
  5. Add Cheese Topping and Bake: Sprinkle the shredded mozzarella cheese evenly on top of the mixture. Place the baking dish in the preheated oven and bake for 30 to 35 minutes until the casserole is browned on top and bubbly.

Notes

  • Using fresh broccoli requires microwaving it to soften before mixing; frozen broccoli can be cooked as per package directions.
  • For extra flavor, optional salt and black pepper can be added, but often the cheeses provide sufficient seasoning.
  • Make sure to drain the cooked broccoli well to avoid a watery casserole.
  • This casserole is great as a keto-friendly side or light main dish.
  • For a dairy-free version, substitute cheeses with non-dairy alternatives.
