This broccoli cauliflower ground beef casserole has it all: flavorful beef, three different vegetables, a creamy, spicy sauce and a crispy, melty, cheesy topping. The recipe was inspired by the flavors of this Buffalo beef dip that is spiced with smoked hot paprika and Louisiana hot sauce.
- This casserole recipe has three different vegetables: cauliflower, broccoli and potato. Rather than going through the trouble of preparing raw potatoes, you use store-bought shredded hash browns from the freezer section of the grocery store.
- I recommend Louisiana hot sauce for this recipe. It's got great flavor and a nice tanginess that really makes the creamy sauce for this casserole pop.

For the beef:
- ½ tablespoon mild olive oil
- ⅓ cup minced white or yellow onion (you should need a little less than ½ of a small onion for that)

- ⅜ teaspoon onion powder
- ⅜ teaspoon garlic powder
- ¾ teaspoon smoked hot paprika
- ⅜ teaspoon salt
- ½ teaspoon ground black pepper
For the broccoli and the cauliflower:

- 1 ½ tablespoons hot sauce, such as Louisiana hot sauce
- 1 ¼ cups grated sharp cheddar cheese, divided into ¾ cup and ½ cup
- Heat the oven to 400 degrees F. and start heating a pot with water and a steamer basket in it. Meanwhile, cook the beef.
Cook the beef:
- Heat the oil in a skillet until shimmering.

- Add the beef and cook until no longer pink (about 6 minutes).
- Pour off all grease, then stir onion powder, garlic powder, paprika, salt and pepper into the cooked beef. Set aside.
Steam broccoli and cauliflower:
- Once the water in the pot is hot, steam broccoli and cauliflower florets to desired doneness. Set aside.
Pre-bake the hash browns:
- Once the oven is preheated, spread the frozen hash browns out on a lightly oiled baking sheet and place in the oven. Bake until hot and just starting to brown on the edges (about 12 minutes). Stir around once halfway through the baking time. Keep the oven running at 400 degrees F.
Make the sauce:
- Add cream cheese and sour cream to a bowl and whip with an electric mixer until combined.
- Whip in the egg, then the cream, then the hot sauce. Set aside.
Prepare the casserole:
- Add beef, broccoli, cauliflower, hash browns and ¾ cups of the cheddar to a large mixing bowl.
- Pour in the sauce and mix well. Transfer to a baking dish and top with the remaining cheddar. Transfer to the oven and bake until the cheese on top is fully melted (25 to 30 min.) Let cool for a few minutes, then serve.
