Tips for the Best Cheesy Broccoli Casserole
🥦 Use Fresh or Frozen Broccoli
Both work well, but if using frozen, make sure to thaw and drain excess water to avoid a watery casserole.
🧀 Add Extra Cheese
For an even richer flavor, mix in some Gouda, Swiss, or Monterey Jack cheese.
⏳ Make it Ahead
Prepare the casserole in advance, cover, and refrigerate before baking. Just add an extra five minutes to the baking time when ready to cook.
🌶 Enhance the Flavor
Try adding crispy bacon bits, sautéed mushrooms, or a pinch of smoked paprika for added depth.
Variations to Try
🥑 Low-Carb Version: Use almond flour instead of all-purpose flour and crushed pork rinds instead of breadcrumbs.
🌶 Spicy Kick: Add a teaspoon of crushed red pepper flakes or diced jalapeños to the cheese sauce.
🍗 Protein Boost: Mix in shredded rotisserie chicken or diced ham for a heartier dish.
🌱 Vegan Option: Use dairy-free cheese, plant-based milk, and a butter alternative for a vegan-friendly version.
