Broccoli Cauliflower Casserole

The most tremendous veggie casserole in the history of veggie casseroles! I started making it around Thanksgiving as an alternative to broccoli-rice casserole, but it has slowly crept into other meals throughout the year. It's irresistible.

Ingredients

4–6 servings

1 cauliflower head
1 large broccoli head
1/2 cup (1 stick) butter
1 medium onion, diced
2 garlic cloves, minced
1/4 cup all-purpose flour
2 1/2 cups low-sodium chicken broth
4 ounces cream cheese, at room temperature
1/4 teaspoon seasoned salt, more to taste
Kosher salt and black pepper to taste
1/4 teaspoon paprika, plus more for sprinkling
1/3 cup seasoned breadcrumbs
1 1/2 cups grated Monterey Jack cheese
  1. Step 1

    1. Preheat the oven to 375°F.

    Step 2

    2. Using your hands, break the cauliflower and broccoli into very small florets. Place them in a steamer and steam them over simmering water until slightly tender, 3 to 4 minutes. Set them aside.

    Step 3

    3. Melt 6 tablespoons of the butter in a large skillet over medium heat, then add the onion and garlic and cook until the onion is translucent, 3 to 4 minutes. Sprinkle in the flour, stirring it into the onion mixture and cook it for a minute or so. Pour in the broth, stirring continuously, and cook the sauce, stirring occasionally, until it begins to thicken, about 3 minutes.

    Step 4

    4. Add the cream cheese and stir until it melts completely. Then stir in the seasoned salt, kosher salt, pepper, and paprika. Turn off the heat and set the sauce aside.

    Step 5

    5. In a small bowl, combine the breadcrumbs and the remaining 2 tablespoons melted butter and blend with a fork.

    Step 6

    6. To assemble, butter a small (2-quart) casserole and add half the broccoli-cauliflower mixture. Pour on half the sauce, top with half the cheese, and sprinkle on a little paprika. Repeat another round of the veggies, sauce, cheese, and paprika...then top the casserole with the buttery breadcrumbs.

    Step 7

    7. Bake the casserole for 25 to 30 minutes, or until the breadcrumbs are golden and the casserole is bubbly around the edges. Serve it nice and piping hot!

  2. Make ahead:

    Step 8

    The casserole can be assembled and stored in the fridge, unbaked, for up to 24 hours. Allow 10 minutes extra cooking time if baking straight out of the fridge.

Variations

This recipe can easily be doubled!

Use all cauliflower or all broccoli, if you prefer.

Use sharp Cheddar cheese instead of Monterey Jack for a slightly different flavor.

Sauté 8 ounces sliced mushrooms with the onions and garlic.

  • I used only 2.0 c chicken broth—use only 1/4 tsp paprika unless you like it hot, I used extra pepper Jack cheese 2 cups in all. I also added in 8 oz sautéed mushrooms and extra minced garlic. If you want a nice crunchy topping, use more Panko herbed bread crumbs mixed with add’l melted butter. Excellent dish, thank you!!

  • It was much too watery with 2.5 cups of broth, so I only added 2.0 cups the next time, which worked out perfectly!! I also liked the Jack Cheese—Absolutely delicious!! I’ll be making it again this weekend.

  • I made it following the recipe except for using a mix of cheddar and gruyere cheese and it was terrific. Everyone loved it and it was a great way to enjoy cauliflower.

  • It was great! I made two changes. 1) I used Swanson Vegetable Broth instead of chicken broth b/c I had vegetarians coming for dinner. 2) I made it in a 1" deep casserole dish, so it was not layered but spread out. I probably could have used more breadcrumbs 'cause it ended up as a hint of crumbs, not a layer. But it was still great!

  • This dish came out great, but I admit that I added some things. First, I put chicken breasts in the pressure cooker with chicken broth. Then when I made the sauce, I added black pepper, herbs de provence, and nutritional yeast + the chicken (shredded). Next time, I would like to try mushrooms like others have suggested. My whole family loved it!

  • i finally made this last night! it came out delicious however, i only used 1/2 stick of butter. it really doesn't need a whole stick. i would also use less cream cheese next time. you don't need a whole package. 1/2 package of cc would be sufficient. i used whatever cheese i had on hand; freshly grated parmesan and pecorino romano. i steamed all the veggies in one pot for a good 10 minutes and threw them in the oven with all the toppings for 25 minutes and 5 minutes under the broiler.

  • I doubled this recipe and was very disappointed in the outcome. It was watery , maybe the steaming of the vegetables made the texture of the casserole so thin. Will not make it again, it was alot of work for poor results.

  • I have made a version of this casserole before, but this one was so much better.

  • This is a really good casserole. I've made it several times. It's very rich and is good paired with something plainer - like a baked chicken breast or perhaps snapper. There are only two of us, so one recipe will feed us for a few days - two dinners and a couple of lunches. I don't think that it would freeze well, so you might want to plan on eating it over the next few days. You could make a half recipe but frankly it's rather a lot of work for only one meal, in my opinion. Great flavor!

  • Was this ever tasty! Added some heat (an inch or so of ring of fire chili), fresh mushrooms, reduced the butter by half, and added Trader Joe's meatless ground meat. Served with rice. An easy vegetarian meal with lots of leftovers for the next day.

  • I made this almost as written - added a pinch of cayenne to the sauce as others have suggested. Additionally, I used approx. 1.5x the veggies with the original amounts of sauce, cheese & crumbs. There was still plenty of cheesy-creamy goodness, even with the larger portion of veggies.

  • Fantastic! I've made this 3 times: the first time exactly as written, the second time with all cauliflower (no broccoli), and the third all cauliflower with cooked chicken added in cubes as a main dish. Wonderful flavor!
