Ingredients
Vegetables
- 3 cups broccoli florets, fresh or frozen
- 3 cups cauliflower florets, fresh or frozen
Cheese Sauce
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk (whole or 2%)
- 1 cup heavy cream (optional for extra richness)
- 1 ½ cups shredded sharp cheddar cheese
- ½ cup shredded mozzarella or Monterey Jack cheese
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- Salt and black pepper, to taste
- A pinch of paprika (optional)
Topping
- ½ cup shredded cheddar cheese
- ¼ cup grated Parmesan cheese
- ¼ cup breadcrumbs (optional, for crunch)
Instructions
- Preheat the oven
Preheat your oven to 375°F (190°C). Lightly grease a medium casserole dish with butter or cooking spray. - Prepare the vegetables
Bring a large pot of salted water to a boil. Add the broccoli and cauliflower florets and cook for 3–4 minutes until just tender but still firm. Drain immediately and run under cold water to stop the cooking process. Pat them dry with paper towels to prevent excess moisture in the bake. - Make the cheese sauce
In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1–2 minutes to remove the raw flour taste. Slowly add the milk, whisking constantly until smooth and thickened. Then pour in the heavy cream if using.
Reduce the heat and stir in cheddar and mozzarella cheeses until melted. Season the sauce with garlic powder, onion powder, salt, black pepper, and a pinch of paprika. The sauce should be creamy and flavorful. Taste and adjust seasoning if needed. - Combine everything
In a large mixing bowl, add the blanched broccoli and cauliflower. Pour the cheese sauce over the vegetables and gently toss to coat everything evenly. Transfer the mixture into the prepared casserole dish, spreading it out in an even layer. - Add the topping
Sprinkle the remaining cheddar and Parmesan cheese evenly on top. If you want a crunchy texture, add breadcrumbs as well. - Bake until golden
Place the casserole in the preheated oven and bake for 25–30 minutes, or until the cheese is melted, bubbly, and lightly golden brown on top. If you like a crispier top, switch the oven to broil for the last 2–3 minutes. - Serve and enjoy
Remove from the oven and let it sit for about 5 minutes before serving. Garnish with freshly cracked black pepper or chopped parsley if desired. Serve warm as a side dish or even as a vegetarian main course.
Serving Suggestions
This cheesy broccoli and cauliflower bake pairs beautifully with roasted chicken, baked salmon, grilled steak, or even pasta dishes. It’s also a comforting vegetarian option on its own, served with crusty bread or a fresh salad.
For holiday dinners, it’s a great addition to the table alongside turkey, mashed potatoes, and stuffing. You can even prepare it a day ahead and bake it just before serving for convenience.
Tips for Perfect Results
- Use fresh vegetables for the best texture, but frozen ones work too — just thaw and drain them thoroughly.
- Add more flavor with spices like nutmeg or a bit of cayenne pepper for a subtle kick.
- Make it gluten-free by using cornstarch instead of flour to thicken the sauce, and gluten-free breadcrumbs if desired.
- Add protein by mixing in diced cooked chicken or crumbled bacon before baking.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for about 10–15 minutes until warm and bubbly again. You can also reheat individual portions in the microwave, though the oven keeps the top crispy.
Conclusion
This cheesy broccoli and cauliflower bake is pure comfort food that’s both simple to make and deeply satisfying. Every bite combines the creaminess of melted cheese with the freshness of perfectly cooked vegetables. Whether you’re preparing it for a cozy family dinner or a festive gathering, it’s a guaranteed hit that brings warmth, color, and delicious flavor to any table.
