Ingredients
Let’s gather our goodies! These are all pretty standard pantry staples, making this recipe a breeze to throw together:
- 2 cups Broccoli florets: Fresh or frozen, these little green trees are packed with goodness.
- 2 cups Cauliflower florets: The perfect partner to broccoli, adding a mild, creamy texture.
- 1 teaspoon Garlic powder: For that irresistible savory punch.
- 1/4 cup Green onions, sliced: For a pop of fresh flavor and a pretty garnish.
- 1 teaspoon Onion powder: Doubles down on that delicious oniony goodness.
- 1/4 teaspoon Black pepper: Just a little something to wake up all those flavors.
- 1/2 teaspoon Salt: To bring out the best in everything.
- 1/2 cup Panko breadcrumbs: These are my secret weapon for the crispiest topping ever!
- 1 cup Cheddar cheese, shredded: Because, well, cheese! Sharp cheddar is my favorite here.
- 1 cup Cream cheese, softened: This is what makes our casserole so luxuriously creamy. Make sure it’s nice and soft!
- 1/2 cup Milk: To help us get that perfect, smooth sauce consistency.
- 1/2 cup Sour cream: Adds a delightful tang and extra creaminess.
How to Make It
Alright, let’s get cooking! This is where the magic happens, and it’s simpler than you might think.
- Preheat your oven: First things first, get that oven nice and warm. Preheat it to 375°F (190°C). This ensures everything bakes up beautifully.
- Get your veggies tender-crisp: You have two easy options here. You can steam your broccoli and cauliflower florets until they’re tender but still have a little bite (we don’t want mushy veggies!). Or, you can give them a quick blanch in boiling water for a few minutes. Once they’re cooked, drain them really well. This step is important so your casserole isn’t watery.
- Mix up that creamy goodness: Grab a big bowl! Add your cooked broccoli and cauliflower. Then, dollop in that softened cream cheese, pour in the milk and sour cream, and sprinkle in the garlic powder, onion powder, salt, and pepper. Now, grab a spoon or a spatula and mix everything together until it’s all beautifully combined and super creamy.
- Into the dish it goes: Lightly grease a baking dish – any oven-safe dish will do. Carefully transfer your creamy veggie mixture into the prepared dish, spreading it out evenly.
- Top it off: This is the best part! Sprinkle that glorious shredded cheddar cheese all over the top, making sure to get it all the way to the edges. Then, scatter the panko breadcrumbs over the cheese for that amazing crunch.
- Bake to perfection: Pop the dish into your preheated oven and let it bake for about 20-25 minutes. You’re looking for that moment when the casserole is bubbly around the edges and the topping is a lovely golden brown. Pure heaven!
- The final flourish: Once it’s out of the oven, give it a moment to cool slightly. Then, sprinkle those fresh, sliced green onions over the top. They add a burst of color and a fresh bite that perfectly complements the rich, cheesy casserole.
Substitutions & Additions
Feeling inspired to get creative? I love that! Here are a few ideas to make this casserole your own:
- Cheese, please! Don’t have cheddar? Monterey Jack, Colby, or a blend of your favorite melting cheeses would be delicious. A little bit of Parmesan sprinkled on top before baking adds a nice salty bite.
- Add some protein: Cooked, shredded chicken, crumbled bacon, or diced ham can be stirred into the veggie mixture for an even heartier meal.
- Spice it up: If you like a little heat, add a pinch of cayenne pepper or some diced jalapeños to the creamy mixture.
- Veggie variations: Feel free to add other quick-cooking veggies like peas, diced carrots, or mushrooms. Just make sure they’re pre-cooked or finely diced.
- Breadcrumb alternatives: If you don’t have panko, regular breadcrumbs work too, though they might not get quite as crispy. Crushed crackers or even a sprinkle of crushed pork rinds can also be used for a lower-carb option.
Tips for Success
A few little tricks can make this casserole absolutely perfect every time:
- Don’t overcook the veggies: You want them tender-crisp so they don’t turn to mush in the oven.
- Soften that cream cheese: This is key for a smooth, lump-free sauce. Let it sit on the counter for about 30 minutes, or give it a quick zap in the microwave (just a few seconds!).
- Drain those veggies well: I can’t stress this enough! Excess water will make your casserole watery.
- Prep ahead: You can totally assemble the casserole (up to the baking step) a day in advance. Cover it tightly and keep it in the refrigerator. You might need to add a few extra minutes to the baking time.
- Crispy topping insurance: If your topping isn’t browning as quickly as you’d like, you can pop it under the broiler for the last minute or two, but watch it VERY closely to prevent burning!
How to Store It
Leftovers are a beautiful thing, especially with this casserole! Once cooled, cover the baking dish tightly with plastic wrap or transfer the leftovers to an airtight container. It will keep nicely in the refrigerator for up to 3-4 days. To reheat, you can pop individual portions in the microwave or warm up a larger serving in a 350°F (175°C) oven until heated through.
FAQs
Here are a few quick questions I often get:
- Can I use fresh broccoli and cauliflower instead of frozen? Absolutely! Fresh is wonderful. Just make sure to cut them into bite-sized florets and follow the steaming or blanching instructions.
- Is this recipe low-carb? It’s lower in carbs than a traditional potato or pasta casserole, especially if you omit or substitute the breadcrumbs. The cauliflower and broccoli are great low-carb bases!
- Can I freeze this casserole? Yes, you can freeze the unbaked or baked casserole. If freezing unbaked, thaw it in the refrigerator overnight and then bake as directed (you may need to add extra time). If freezing baked, thaw and reheat as described in the storage section.
I hope you give this Loaded Cauliflower and Broccoli Casserole a try soon. It’s more than just a meal; it’s a feeling of warmth and happiness on a plate. Enjoy!
