    How to Make Cauliflower Casserole

    You don’t need anything fancy to make this easy broccoli and cauliflower casserole. It is a perfect combination of ingredients and good old comfort food. You can also play around with the ingredients to make it your own!

    Ingredients You’ll Need

    • Broccoli Florets & Cauliflower Florets – Use about 1.5 to 2 pounds of florets. These will be pre-cooked for a few minutes before we add them to the casserole dish.
    • Vegetable Oil – For cooking the aromatics and sausage.
    • Onion & Garlic – I suggest using fresh onions and garlic here – they add texture, flavor, and a delicious bite.
    • Polish Sausage or Andouille Sausage – Or any other pre-cooked sausage.
    • Cream Cheese – Try your best to use room-temperature cream cheese because it will mix better with the rest of the ingredients.
    • Mayonnaise – Plain yogurt or sour cream also work great as substitutions.
    • Shredded Cheeses – Use your favorite blend.

    Directions

    Ideal for weeknight dinners or casual get-togethers, this casserole is ready to be the star of your dinner table. It’s a simple sausage bake packed with robust flavors, fresh veggies, and a creamy cheese blend.

    1. Preheat the oven to 400˚F and grease a 9×13 baking dish with butter or cooking spray; set aside.
    2. Add broccoli and cauliflower florets to boiling water and cook for 3 minutes; drain and set aside.
    3. Heat vegetable oil in a large skillet, stir in the onions, and cook for 2 minutes. Stir in the garlic and smoked sausage, and cook until browned on all sides.
    4. Transfer broccoli, cauliflower, and sausage mixture to the baking dish.
    5. Combine the cream cheese, mayo, shredded cheese, dijon mustard, salt, and pepper in a mixing bowl; add it to the broccoli mixture and stir until combined.
    6. Sprinkle remaining shredded cheese over the top and bake for 12 to 15 minutes or until golden brown.

    Recipe Tips

    • Grease the baking dish: Make sure you don’t forget to grease your baking dish. It will make your life so much easier! Just a dash of cooking spray will do the trick. If you don’t grease the pan, the bottom of your casserole might stick to it.
    • Sausage options: While you can use any pre-cooked sausage, consider using one with a strong flavor profile, such as Polish or andouille sausage, to enhance the overall taste of the casserole.
    • Cooking the vegetables: Make sure to pre-cook your broccoli and cauliflower just enough so they’re tender but still have a bit of crunch.
    • Use different veggies: This casserole can easily be adapted to suit your tastes. Feel like switching up the veggies or cheese? Go for it! The recipe is flexible.

    Serving Suggestions

    This is a versatile dinner recipe that pairs well with just about anything!

    How to Store and Reheat Leftovers

    • This dinner almost never makes it past the first night at my house. But if you do end up with leftovers, you can easily save them for later! Just store your casserole in an airtight container in the refrigerator for 3 to 4 days.
    • To reheat, put it in the oven at 350°F for 15 minutes or until it’s nice and hot.

      Unbelievably tasty recipe- I got a bit creative and substituted sausage for vegan sausages, used a touch of almond milk and vegan butter instead of cream cheese, used vegan mayo and it was DIVINE!

        Easy and versatile. I donโ€™t eat mustard or mayo, used sour cream and mustard seasoning and used flavored chicken sausage. Very good. This would be great for picky veggie eaters cause the flavor for me was the meat and cheese mixture. If your a big meat or veggie eater you could easily double either.

          I am very glad you enjoyed it!! I need to try your version with sour cream, sounds really good! Thank YOU! ๐Ÿ™‚
