Keto Broccoli Cheese Casserole is a creamy, cheesy, low-carb side dish featuring tender broccoli in a rich cheese sauce, baked to bubbly perfection. It’s a satisfying and wholesome option for keto and gluten-free diets, ideal for weeknights, holidays, or meal prep.

Ingredients

  • 4 cups broccoli florets (fresh or frozen)
  • 2 tablespoons butter
  • 4 oz cream cheese, softened
  • 1/2 cup heavy cream
  • 1 1/2 cups shredded cheddar cheese, divided
  • 1/4 cup grated Parmesan cheese
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • Optional topping: 1/4 cup crushed pork rinds or almond flour
  • Optional mix-ins: cooked bacon or shredded chicken

Instructions

  1. Preheat oven to 375°F (190°C). Grease a casserole dish.
  2. Steam or boil broccoli for 4–5 minutes until just tender. Drain well and set aside.
  3. In a saucepan, melt butter over medium heat. Stir in cream cheese until smooth.
  4. Add heavy cream, garlic powder, onion powder, salt, and pepper. Simmer for 2–3 minutes.
  5. Stir in half the cheddar and all the Parmesan. Mix until smooth and creamy.
  6. In a large bowl, combine broccoli and cheese sauce. Mix to coat evenly.
  7. Transfer to the casserole dish. Top with remaining cheddar and optional topping.
  8. Bake for 20–25 minutes until golden and bubbly. Broil for 1–2 minutes if desired.
  9. Let cool slightly before serving.

Notes

  • Drain broccoli well to prevent a watery casserole.
  • Use pre-shredded cheese for convenience, or freshly grate for best melt.
  • Add cooked chicken or bacon to turn it into a complete meal.
  • Great for make-ahead and freezer-friendly meal prep.
