Equipment

  • 9x13-inch Baking Dish
  • Medium Pot
  • Skillet
  • Large Mixing Bowl

Ingredients
  

  • 4 cups fresh broccoli florets chopped into bite-sized pieces
  • 10 large eggs
  • 1 cup milk whole or 2% works best
  • 2 cups sharp cheddar cheese shredded and divided
  • 1 small onion finely diced
  • 3 cloves garlic minced
  • 2 tablespoons olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon cayenne pepper optional

Instructions
 

  • Preheat your oven to 350°F (175°C) and lightly grease a 9x13 inch baking dish.
  • Bring a medium pot of salted water to a boil. Add broccoli florets and blanch for just 2 minutes. Immediately drain and rinse with cold water to stop the cooking process.
  • Heat olive oil in a skillet over medium heat. Add onions and sauté until translucent, about 3-4 minutes. Add minced garlic and cook for another 30 seconds until fragrant.
  • In a large bowl, whisk eggs until well combined. Add milk, 1 1/2 cups of the shredded cheddar (reserving 1/2 cup for topping), salt, pepper, thyme, and cayenne if using. Whisk until fully incorporated.
  • Fold the blanched broccoli and sautéed onion-garlic mixture into the egg mixture. Pour everything into your prepared baking dish, ensuring the broccoli is evenly distributed. Sprinkle the remaining 1/2 cup of cheddar cheese on top.
  • Bake in the preheated oven for 40-45 minutes, or until the center is set and the top is golden brown. A toothpick inserted in the center should come out clean.
  • Let the casserole rest for 5-10 minutes before serving.

Notes

For a healthier version, use 5 whole eggs and 5 egg whites to reduce cholesterol without sacrificing texture.
Make-ahead option: Assemble everything except the final cheese topping, cover, and refrigerate overnight. Add cheese before baking and extend cooking time by 10 minutes.
Store leftovers in airtight containers for up to 4 days in the refrigerator or freeze individual portions for up to 2 months.
