Updated: Jun. 28, 2024

Though you may solely associate broccoli cauliflower casserole with the holidays (most notably, Thanksgiving), this dish should be enjoyed anytime. Our recipe results in a creamy, tangy, well-seasoned mix of veggies and cheese topped with crispy, seasoned stuffing—it’s near-impossible to resist. If you’re craving some good ol’ comfort food, broccoli cheese casserole will make you feel fulfilled on every level.

Ingredients for Broccoli Cauliflower Casserole

  • Cauliflower: We love the texture that a medium head of cauliflower brings to this casserole (it’s also a great source of nutrients).
  • Broccoli: If you want your broccoli (and cauliflower, for that matter) to have a crisper texture, roast it in the oven, rather than boiling it, before adding it to the casserole. Roasting veggies in olive oil, salt and pepper brings out their natural flavor.
  • Monterey Jack cheese: Substitute shredded Monterey Jack for shredded sharp Cheddar cheese if you’d prefer. A mix of cheeses would work well, too.
  • Sour cream: While you could use cream of mushroom, sour cream has a rich tanginess that’s hard to mimic.
  • Green chiles: Chopped green chilies add an excellent heat to broccoli cheese casserole.
  • Butter: Butter provides richness and structure to the stuffing topping (and the casserole in general).
  • Seasoned stuffing: Seasoned stuffing gets deliciously crispy when baked in the oven, which complements the creaminess of this casserole.

Directions

Step 1: Boil the veggies

Place 1 inch of water in a Dutch oven. Add the cauliflower and broccoli and bring to a boil. Reduce the heat, cover and cook for seven minutes or until tender.

Step 2: Combine the other ingredients

Combine the cheese, sour cream, chiles, two tablespoons of butter, salt and pepper. Drain the vegetables well and gently fold them into the cheese mixture.

Step 3: Bake

Transfer to a greased 2-1/2 quart baking dish. Toss the stuffing and remaining butter and sprinkle it over the vegetables. Bake, uncovered, at 350°F for 20 to 25 minutes or until heated.

Broccoli Cauliflower Casserole Variations

  • Use Ritz crackers: Buttery Ritz cracker crumbs are an excellent topping for broccoli cauliflower casserole.
  • Add Dijon mustard: Dijon gives this casserole a nice bite. Add a teaspoon with the rest of the ingredients in Step 2.
  • Finish with fresh parsley and crispy fried onions: If you want to really take this dish to the next level fry up some onions in oil (until crispy) and finely chop a bit of fresh parsley while the casserole is baking. Add these to the top of the casserole when it is done.

How to Store Broccoli Cauliflower Casserole

Can you make this casserole ahead of time?

You could make this casserole the day before. Simply assemble the ingredients (leave off the stuffing topping), cover the dish tightly with foil and refrigerate. When ready to bake it, let the casserole come to room temperature and add the stuffing. Please be sure to bake according to the recipe.

Broccoli Cauliflower Casserole Tips

Can I make this broccoli cauliflower casserole vegan?
