At Sweet C’s, I add lots of tips in all of my recipes – because I am a home cook without any formal training, and I find I am more confident making dishes when I understand why it works, and what each ingredient means to the flavor of a recipe – my goal is for even the most beginner home cook to feel empowered in the kitchen.

I want each reader to walk away with a solid knowledge of each recipe, with all of the tips I’ve gathered from extensive testing of each recipe. I also answer questions my friends and family have asked about my recipes, to help everyone better understand the processes we use – and why!

How to make Cauliflower Broccoli Sausage Casserole

First you will want to assemble and prepare the following ingredients:

  • Broccoli florets – Broccoli adds a slightly sweet and nutty flavor to a cheesy casserole, which contrasts well with the rich and savory cheese sauce.
  • Cauliflower florets – Cauliflower adds a mild and slightly sweet flavor to a cheesy casserole, which helps to balance the richness of the cheese and sausage.
  • Olive oil – olive oil is a great oil to sauté vegetables and brown before adding to a casserole, adding depth and heart-healthy fats to the dish.
  • Yellow Onion – Yellow onion brings a savory and slightly sweet flavor to a cheesy casserole, which provides a rich and aromatic base for the dish.
  • Garlic – Garlic adds a pungent and slightly spicy flavor to a cheesy casserole, which helps to balance the richness of the cheese and sausage, and adds depth and complexity to the dish.
  • Smoked sausage or andouille – smoked sausage adds a protein hit and rich flavor, you can use beef or pork sausage.
  • Cream cheese – cream cheese adds some lovely fat to this casserole and thickens the cheese sauce.
  • Mayonnaise – mayo is the base for the creamy casserole.
  • Mexican blend cheese – this cheese blend is a mixture of Monterey jack, Colby, and cheddar cheese with some added spices.
  • Dijon mustard – Dijon mustard is distinct from regular mustard because it has horseradish and white wine in it which gives this casserole a wonderful flavor.
  • Sea salt – use high quality sea salt to season the veggies and sausage.
  • Fresh cracked black pepper – pepper adds a wonderful heat that balances out this dish. Add extra pepper if you want it spicier.

Tips and Tricks for a Perfect Cheesy Casserole

Blanch or sauté the broccoli and cauliflower: Parcooking the vegetables before baking helps to soften them and ensure even cooking.

Use high-quality sausage: Choose a high-quality sausage with a bold flavor that can stand up to the other ingredients in the casserole.

Use a blend of cheeses to kick up the flavor: A blend of cheeses such as cheddar, mozzarella, and parmesan will provide a more complex and flavorful sauce than using just one type of cheese.

Season well: Don’t be shy with the seasonings. Use a generous amount of salt, pepper, and any other seasonings you like to bring out the flavors in the dish.

Don’t overcook: Be careful not to overcook the casserole, as this can cause the cheese to become stringy and the vegetables to become mushy.

Let it rest: Allow the casserole to rest for a few minutes after baking, as this will allow the flavors to meld together and make it easier to serve.

    Looks delicious. Sodium count per serving is a lot. Any suggestions?

    1. Katherine says:

      The sausage has some salt, if you want to omit the sea salt you can or just add some just before serving.
