Recipe Ingredients
- Broccoli Florets & Cauliflower Florets: This recipe uses a pound of each, but you can add more broccoli and less cauliflower or vice versa. You could add other veggies, such as green beans or asparagus, too.
- Garlic-Flavored Olive Oil: Adds a rich garlic flavor. Regular olive oil can be used with a pinch of garlic powder as a substitute.
- Yellow Onion: I like to use a small yellow onion, but white onion can work in a pinch.
- Garlic: Use about 1/2 teaspoon garlic powder if fresh garlic isn’t available.
- Salt and Black Pepper: Essential seasonings to enhance all the flavors. Kosher salt and pre-ground pepper are okay to use.
- Shredded Cheddar Cheese: Adds a sharp, creamy flavor to the sauce, but you can substitute it with Monterey Jack or Gruyère for a twist.
- Cornstarch: Thickens the cheese sauce for a creamy consistency. All-purpose flour or arrowroot powder can be used as alternatives.
- Evaporated Milk: This will create a rich, creamy base for the sauce without being too heavy. Regular whole milk or half-and-half will also work.
- Dijon Mustard: Adds a tangy depth of flavor to the sauce. Yellow mustard or a pinch of mustard powder can be used instead.
- Smoked Paprika: Regular paprika or a dash of cayenne pepper will also work.
- Shredded Mozzarella Cheese: You can try other cheeses, such as Provolone or Fontina cheese.
How To Make Cauliflower Broccoli Bake
This vegetable casserole is a veggie-packed cheesy classic packed with bold flavors and plenty of comfort! Loaded with cheese and garlic, it’s the ultimate side dish for any meal. Follow these simple steps to make it!
- Cook the Veggies: We’ll quickly steam our cauliflower and broccoli, then sauté them with some onion and garlic tossed in delicious garlic-flavored olive oil.
- Make the Cheese Sauce: In the meantime, we’ll whip up a simple lightened-up cheese sauce. I found this recipe gem in an old Weight Watchers cookbook, and I’ve been hooked ever since. It’s just evaporated milk, shredded cheddar, and a touch of cornstarch.
- Pro Tip: Keep your flame low while making the sauce. High heat makes the sauce grainy, especially with reduced-fat cheeses. Nobody wants grainy cheese sauce, am I right?
- Combine and Bake: Next, we’ll marry our sautéed veggies and glorious cheese sauce, then slide it into the oven. Around 20 minutes later, you’ll be face-to-face with a hot, bubbly, and insanely delicious cheesy cauliflower bake.
Recipe Tips & Variations
- Using Frozen Veggies: Yes, you can use frozen cauliflower and broccoli florets, but cook them according to the instructions on the package and drain any excess liquid before combining the veggies with the cheese sauce.
- Vegetable Alternatives: You can swap out the cauliflower for another veggie. Any vegetable that’s been lightly roasted, given a quick steam, or even blanched would be a great fit. Try Brussels sprouts, green beans, or more broccoli.
- Cheese Sauce: Remember to keep the heat low when you’re making the cheese sauce to avoid a grainy texture. Stir continuously for a smooth, creamy sauce.
- Switch up the Cheese: Feel free to play around with the types of cheese in this dish. A blend of cheddar and gruyere or a sprinkle of parmesan can add a different twist to your casserole.
- Add-ins: Add some protein like cooked chicken, bacon, or even canned tuna.
- Seasoning: Don’t forget to season your veggies during the sautéing phase. A little salt and pepper can make a huge difference in the overall flavor of the dish.
Serving Suggestions
This cauliflower broccoli casserole is the perfect complement to a variety of dishes, making it a delicious addition to your meal plan. Serve it alongside grilled or roasted meats like oven baked chicken breasts, juicy roast beef, air fryer pork chops, or a perfectly seared ribeye steak for a hearty and satisfying dinner.
For a lighter option, pair this cheesy bake with flaky sockeye salmon or tender cod. And if you’re craving something fresh, a crisp tabbouleh salad or tangy cabbage cucumber salad adds a refreshing balance to this rich and comforting casserole.
How To Store & Freeze
- To Store: Transfer leftovers to an airtight container and keep in the fridge for 2 to 3 days or in the freezer for 2 to 3 months.
- To Reheat from Frozen: Place it in your microwave on high for around 3 to 4 minutes. The exact time might vary based on your microwave’s power. Let it sit briefly after you take it out.

Notes
