Ingredients
- 3 cups broccoli florets fresh preferred, or frozen
- 2 cups cauliflower florets for cream sauce
- 2 cups cooked chicken breasts chopped
- 2 tablespoons olive oil extra virgin preferred, divided
- 2 tablespoons nutritional yeast or grated Parmesan cheese
- ¼ teaspoon salt adjust to taste
- ⅛ teaspoon black pepper
- ¼ teaspoon garlic powder
- ¼ teaspoon onion powder
- 3 oz cheddar cheese freshly shredded
Instructions
- Make Cauliflower Cream Sauce:
- Add cauliflower florets to a medium saucepan and cover with just enough water.
- Simmer over medium heat until fork-tender (5–7 minutes), then drain, reserving ½ cup of cooking water.
- Blend cauliflower with 1 tablespoon olive oil, nutritional yeast/Parmesan, salt, pepper, garlic powder, and onion powder until smooth and creamy. Add reserved water gradually to adjust consistency.
- Prepare Casserole:
- Preheat oven to 375°F (190°C) and grease an 8×8-inch baking dish with remaining olive oil.
- Microwave broccoli with 2 tablespoons water for 3–4 minutes, until just tender.
- In a large bowl, mix broccoli, cooked chicken, and cauliflower sauce until combined.
- Transfer mixture to the prepared dish and top with shredded cheddar cheese.
- Bake:
- Bake uncovered for 15–20 minutes, until cheese is melted and edges are golden.
- Optional: Broil for 1–2 minutes for a crispier top. Let rest 5 minutes before serving.
