Whether you're feeding a crowd or just looking for a satisfying meal for yourself, this casserole is versatile and easy to make.

Ingredients:

  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • 1 tablespoon olive oil (if using fresh broccoli)

Cooking Instructions:

Preheat your oven to 350°F (175°C). If you're using fresh broccoli, heat the olive oil in a large skillet over medium heat and sauté the broccoli for about 3-5 minutes until bright green and slightly tender.
