How to Make Cauliflower Casserole
You don’t need anything fancy to make this casserole. You can also play around with the ingredients to make it your own!

Directions
- Preheat the oven to 400˚F and grease a 9×13 baking dish with butter or cooking spray; set aside.
- Add broccoli and cauliflower florets to boiling water and cook for 3 minutes; drain and set aside.
- 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.
- Transfer broccoli, cauliflower, and sausage mixture to the baking dish.

Tips for Broccoli Cauliflower Casserole
- Lightly Grease Your 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: 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.
- Pre-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.
- Don’t Overcook Your Garlic: The garlic cloves will cook quickly, so make sure you keep an eye on them. You don’t want them getting too hard and burnt.
- Stir the Sausage: In order to get your smoked sausage browned evenly, you’ll have to stir it often while it’s cooking with the garlic and onions.
Serving Suggestions
This is a versatile dinner that pairs well with just about anything! Here are some of my favorite sides to serve it with:
- Roasted Carrots: These Maple Roasted Carrots are sweet, buttery, and super easy to throw together. Their sweetness compliments the savory sausage casserole while keeping your dinner healthy and fresh.
- Deviled Avocados: These creamy Deviled Avocados are fun, simple, and full of flavor. They have a cool, smooth texture that will go great with your cauliflower bake. Or how about these Air Fryer Avocado Fries!
- Cocktails: After a long day when you just want to sit down with a relaxing meal, throw together a cocktail to enjoy with this casserole. My Cucumber Mojitos and Apple Cider Mimosas are easy options that never fail to satisfy.
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.

Love this recipe. Does it make 8 servings? I’m assuming so but thought I’d ask
Hi!
Yes, it’s 8 servings.
The base with the cream cheese, mayo, mustard, and S&P is good but definitely makes more cream than needed for the measurements of what you’re mixing into it. I used two 12-ounce bags of California Medley steamable vegetables (broccoli, cauliflower, and carrots) and one kielbasa link and – though it was good – it needed more substantiality to it. Next time, I am going to add a cup or so of precooked jasmine rice to the whole thing so that it’s a full dinner in one dish.
Oh, and I didn’t even soften the cream cheese. I put the pan-fried kielbabsa and garlic into a large bowl, put all the cream mixture ingredients and all the shredded cheese on top of that, dumped the still-hot steamable veggies on that, and let it sit for about 5 to 7 minutes so the heat softened everything. Then, I mixed it slowly with a rubber spatula, scooped it into the sprayed 9×13 dish, and baked it for 20 minutes.
Very good. Definitely will make it again.
Will definitely make this again! Did not have enough smoked kielbasa, so also browned/cooked 2 links of fresh and added to what I had. Delicious! Picky husband went for seconds! 😋
This is amazing! I added carrots and green beans, so more variety of veggies. Otherwise, made the recipe as is and I will definately make it again!
That’s great! I’m very glad you enjoyed it! Thank YOU! 🙂
Can you use frozen broccoli and cauliflower in this recipe? Thank you😊
I boiled frozen until tender, then added as called for in recipe. Great results!
Can this be frozen?
Technically, yes, you could, but my advice is to avoid freezing dairy-heavy casseroles because ingredients such as heavy cream or cream cheese will separate when frozen, which can result in a grainy texture when defrosted.
I tried this recioe and found it really tasty. I didn’t need the sausage but it did add another dimension to the dish. Next time I’ll add a little more cream cheese. Great!
Hi, do you believe this could be made in the crockpot?
I’ve made this recipe twice now and my ONLY complaint is that it takes so long to put together. I don’t see how it can be put together in just 20 minutes? I made recipe exactly (except use Light Laughing Cow rather than cream cheese) and it is unbelievable how tasty it is. My husband went on and on about how delicious it is.
Per other comments, It only looks like there isn’t enough sauce for the vegetables / sausage but it is so rich you don’t need anymore (and I wouldn’t want anymore). It’s perfect. I did raise an eyebrow when I saw Dijon mustard, but you don’t taste it and this truly is one of the best broccoli casseroles I’ve ever tasted.
I’m very glad you enjoyed it! Thank YOU! 🙂
Really loved the finished cassserole but had to make several changes to make it a great finished product. There was not nearly enough sauce, it would have been a dried up mess if prepared per the recipe. Added about 1/2 cup cream, w eggs slightly beaten and another cup of cheese to the sauce to even coat the veggies and meat.
That should have said two eggs in my review above.
I don’t know what I did wrong! This was terrible! I followed instructions to the letter. Waaay too much cream cheese … neither my daughter nor I liked it! Threw it out.
It looks like you have cherry tomatoes in this recipe. Which sound delicious. Otherwise what if the red stuff on top?
That’s smoked sausage.
Made this for dinner tonight. It was amazing. In regards to WW is it 17 points total for the whole casserole or 17 points a serving?
I was excited for this recipe, but it just didn’t turn out as good as I was expecting. My husband looked at the recipe and said it looked for yummy for dinner. But we were both disappointed. Neither of my kids liked it either. They’re good eaters and they could barely finish their servings. Can’t exactly pinpoint what didn’t taste right, it was just lacking.
Made this tonight for dinner and used 1lb each of broccoli and cauliflower. I didn’t love the smoked sausages I used so would just use my regular favourite sausages next time. I was also expecting the sauce to be a little creamier. I have a similar recipe and it calls for a bit of milk which I would use next time to make this sauce creamier. Otherwise very good dish, very flavourful. Will make again with mentioned changes.
Delicious! My fiance says very flavorful. Will be adding this to my dinner rotation menus. Thanks for sharing!
I’m very glad you enjoyed it! Thank YOU! 🙂
can I freeze it
Hi!
You can definitely freeze it, but when thawing you risk the cream separating and the result might be a grainy casserole.
Can you make this up ahead of time, then bake when ready?
Can I use frozen veggies?
Yes, that will work.
Made this last night and it was delicious! I didn’t have cauliflower florets so I just used riced. And I added a little more sausage (to use the rest of my open package). Turned out really good – would def make again.
That’s wonderful! I am very glad you enjoyed it! Thank YOU! 🙂
Made this tonight, used a steam bag of cauliflower/broccoli and it was delicious! Can’t wait to try more of your recipes!
That’s great! I’m very glad you enjoyed it! Thank YOU! 🙂
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!
Its sitting on the side ready for my partner to taste and hes going to LOVE IT!
I’m so happy to hear that! I am very glad you enjoyed it!! Thank YOU! 🙂
Just a question if I don’t want to use cream cheese what would you suggest I used
One of the tastiest things I have ever put in my mouth. I was smart to make two batches LOL All of the flavors just come together AMAZING
I am very glad you enjoyed it! Thank you so much, Jolene! 🙂
Going to make this tomorrow night. Looks yummy
That’s great! I hope you enjoy it! Thank YOU! 🙂
Easy and versatile. I don’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! 🙂
I love an easy and cheesy casserole like this! I have added this to my menu for next week.
I hope you enjoy it! Thank YOU! 🙂
My kids are still raving about this casserole! Thank you for the easy recipe!
