When all four come together? You get an explosion of healthy ingredients and amazing flavor.
This broccoli cauliflower bake is predominantly veggies (as opposed to this chicken broccoli bake), but the cream cheese, sour cream, cheddar cheese, and bacon add filling fats and proteins to it.
That makes the perfect THM S, keto, or low carb dinner - filling, satisfying, and tempting. Pair it with a tossed salad and you’ve got the perfect meal that everyone will love.
What’s In This Cheesy Broccoli Casserole?
So what do you need to make this gooey, savory dish? Only 6 ingredients and spices you’ve already got in your pantry!
Frozen Mixed Broccoli & Cauliflower (you can usually buy them mixed, but combining them yourself is possible, too)
- Bacon, cooked and crumbled
- Onion
- Sour Cream
- Cream Cheese
- Garlic Powder
- Pepper
- Cheddar Cheese
- Scallions for garnish
While the vegetables in it are super healthy, the additional ingredients make it quite indulgent. Just think about how good it’s going to taste…ready to get cooking?
How Do You Make This Easy Low Carb Casserole With Bacon & Cheese?
Because you’re starting out with frozen broccoli and cauliflower, the preparation for this simple dinner is super easy. There’s no washing, cutting, and prepping your vegetables necessary. Nice, right?
To start, simply cook your frozen vegetables according to the directions on the package and drain them well. This is to avoid any water in the bottom of your finished casserole dish. Set them to drain in a colander while you do the rest of your prep.
While they are draining, fry up your bacon in a skillet. Once it’s nice and crispy, pull it aside and cook your onions in the remaining grease. Don’t caramelize them, just cook them until translucent and fragrant. Remove them from the skillet, and drain them on paper towels or in a colander.
In a mixing bowl, combine your softened cream cheese, sour cream, cheddar cheese, and spices well. You can do this with a spoon or a mixer; whichever you prefer.
Once the cheeses and spices are well combined, add in your onions, broccoli, and cauliflower.
Spread the mixture into your favorite greased baking dish (or cast iron pan) and top with the rest of the shredded cheddar and bake it until it’s all nice and bubbly.
Right before serving, top it with the crispy bacon and scallions.
Can I Make This Meat Free?
If you’d like to make this recipe without the bacon, you can fry the onions in some oil. Consider adding a clove of freshly minced garlic, too.
What If I Don’t Have A Frozen Vegetable Mix?
This recipe will work with all broccoli or all cauliflower, too, you’ll just taste the individual vegetable more than when you use a mix.
Can I Make This With The Vegetables Frozen?
Do you have to pre-cook the cauliflower and broccoli mix, or can you make this amazing recipe even simpler by using them frozen?
You can, but the casserole will be more watery because you won’t have drained the vegetables. If you don’t mind that, go right ahead.
Alternatively, you could halve the sour cream and add some extra cream cheese to help offset it. While it won’t completely solve the watery issue, it will help.
Additional Variations For Cheesy Broccoli Cauli Bake
There are tons of ways to use this recipe over and over and make it taste fresh if you’d like it to be a regular part of your menu rotation.
Consider using pepper jack cheese and maybe adding some diced jalapeños or a can of rotel.
Use Swiss cheese and some blue cheese crumbles for a Bacon and Bleu loaded broccoli cauliflower casserole.
If you’d like to go Caprese style, use mozzarella and add some fresh basil, oregano, and sprinkle with freshly diced tomatoes for some color.
To make it taco style, sub taco seasoning for the spices and double the amount. Use a Mexican cheese blend and add cilantro. Garnish with diced avocados and taco meat instead of bacon.
Making And Storing Your Broccoli Cauliflower Casserole
There’s just something about broccoli that melds beautifully with melty, gooey, savory cheese and spices.
In fact, you can enjoy it with this chicken broccoli casserole, too. Or this ham and broccoli one.
And casseroles like this are super easy. They can be served fresh or made ahead and reheated easily.
This and other casseroles like it are perfect freezer dinners.
You can do everything except for bake them and put them in the freezer for up to 3 months (or the fridge for up to 3 days) and just pull them out when it’s time to bake them.
This makes them the ideal meal to bring to a new mom, busy family, friend who is moving, or have stashed for your own busy night to help you avoid takeout.
If you have leftovers, just store them in an airtight container. They’ll keep for several days in the fridge.
Reheat in the oven or the microwave, uncovered so the vegetables don’t get mushy.
