A simple, rich, and low-carb casserole featuring tender broccoli baked in a creamy, cheesy sauce.

Ingredients

Scale
  • 4 cups fresh or frozen broccoli florets, cooked until tender-crisp
  • 4 tablespoons unsalted butter
  • 4 ounces cream cheese, softened
  • 1 cup heavy whipping cream
  • 1 cup shredded sharp cheddar cheese, plus extra for topping
  • 1/2 cup grated Parmesan cheese
  • 2 large eggs, lightly beaten
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper
  • 1/4 cup almond flour (optional, for slight thickening)

Instructions

  1. Preheat your oven to 375°F (190°C). Grease an 8×8 inch baking dish.
  2. If using fresh broccoli, steam or boil it until it is tender-crisp. Drain well and set aside.
  3. In a medium saucepan over medium heat, melt the butter. Add the cream cheese and stir until smooth.
  4. Whisk in the heavy cream until the mixture is fully combined and starting to simmer lightly.
  5. Remove the saucepan from the heat. Stir in the cheddar cheese and Parmesan cheese until melted and smooth.
  6. Whisk in the garlic powder, salt, and pepper. If you are using almond flour, whisk it in now.
  7. In a separate bowl, lightly beat the eggs. Temper the eggs by slowly whisking about half a cup of the hot cheese sauce into the eggs. Then, pour the tempered egg mixture back into the main cheese sauce, stirring quickly to combine. Do not return the sauce to the heat after adding the eggs.
  8. Gently fold the cooked broccoli florets into the cheese sauce until they are evenly coated.
  9. Pour the mixture into the prepared baking dish. Sprinkle the top with extra shredded cheddar cheese.
  10. Bake for 20 to 25 minutes, or until the casserole is bubbly and the top is golden brown.
  11. Let the casserole rest for 5 minutes before serving.

Notes

  • Cook the broccoli just until tender-crisp; overcooked broccoli will become mushy after baking.
  • You can prepare this casserole ahead of time; cover and refrigerate for up to 24 hours before baking. Add 5-10 minutes to the baking time if baking directly from the refrigerator.
  • This dish pairs well as a side for grilled steak or chicken.
