ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• Cauliflower florets

• Broccoli florets

• Butter

• All-purpose flour

• Milk

• Garlic (optional, minced)

• Cheddar cheese, shredded

• Parmesan cheese

• Salt and pepper

• Dijon mustard (optional, for extra depth)

• Bread crumbs or crushed crackers (for topping)

directions

1. I preheat the oven to 375°F (190°C) and grease a medium-sized baking dish.

2. I steam or blanch the broccoli and cauliflower for 3–4 minutes until just tender, then drain and set aside.

3. In a saucepan, I melt butter over medium heat and whisk in the flour to make a roux. I cook it for about 1–2 minutes until golden.

4. I gradually whisk in the milk, stirring constantly until the sauce thickens.

5. I stir in salt, pepper, and Dijon mustard if using, then add the shredded cheddar and some of the Parmesan. I stir until the cheese melts into a smooth sauce.

6. I combine the broccoli and cauliflower with the cheese sauce and pour it all into the prepared baking dish.

7. I sprinkle the top with bread crumbs, crushed crackers, or more cheese for a crisp topping.

8. I bake for 20–25 minutes, or until bubbly and golden on top.

9. I let it cool for a few minutes before serving.

Servings and timing

This recipe makes about 4–6 servings. It takes around 15 minutes to prep and 25 minutes to bake, so I can have it ready in about 40 minutes total. It’s a perfect weeknight side dish or vegetarian main.

Variations

Sometimes I add cooked bacon, ham, or shredded chicken to make it more filling. I’ve also mixed in other vegetables like spinach or mushrooms. For a different cheese profile, I swap in Gruyère, mozzarella, or a spicy pepper jack. If I want a lower-carb or gluten-free version, I skip the flour and use cream cheese to thicken the sauce instead.

storage/reheating

I store leftovers in an airtight container in the fridge for up to 3 days. To reheat, I bake it at 350°F (175°C) until warmed through, or microwave in smaller portions. If the top softens, I sprinkle on some extra cheese or breadcrumbs and broil for a couple of minutes to bring back the crisp texture.

FAQs

Do I have to cook the broccoli and cauliflower before baking?

Yes, I lightly steam or blanch them first so they’re tender by the time the bake is done. Raw florets may stay too firm after baking.

Can I make this ahead of time?

Yes, I assemble it ahead, cover it, and refrigerate it for up to 24 hours. I bake it just before serving and add a few extra minutes to the bake time if it’s coming straight from the fridge.

What’s the best cheese to use?

I usually go with sharp cheddar for its bold flavor, but feel free to mix it with mozzarella, Gruyère, or any melty cheese you like.

Can I freeze this bake?

Yes, I freeze it after assembling but before baking. I thaw it overnight in the fridge and bake it as directed. Freezing after baking works too, but the texture may soften slightly.

How do I make it more creamy?

If I want it extra creamy, I add a splash of cream or a spoonful of cream cheese to the sauce. It makes the texture silkier and more indulgent.

Conclusion

Cauliflower and Broccoli Bake is one of those go-to recipes I turn to again and again—easy, cheesy, and always a hit. Whether I’m sneaking more veggies into dinner or bringing a crowd-pleasing side to the table, this dish never disappoints.
