This Low Calorie Cheesy Cauliflower Casserole is just 86 calories! Plus it's low carb, low sugar and packed with flavor!I love making this healthy cheesy cauliflower casserole for a side dish, but more often than not I end up splitting the entire casserole with my kiddo as a big low calorie dinner. Special Tip: You can roast the cauliflower ahead of time to make this even quicker to assemble. I like to do it all at once (so I only need to clean up once.)
Preheat the oven to 450 degrees and add the cauliflower florets to a 9x13 casserole dish.
Spray with olive oil and bake for 20 minutes.
Meanwhile, while the cauliflower cooks, make the cheese sauce.
In a large pan, melt the butter over medium-low heat. Add the flour and mix with a wooden spoon, continuously, until you have a light brown paste.
Add in 1 cup of milk and whisk well to remove any lumps. Mix the remaining milk and whole garlic cloves. Increase the heat to medium-high.
Mix often, scraping the bottom of the pan often, until the sauce has thickened and coats the spoon. Turn off the heat, remove the garlic cloves and discard.
Stir in the cooked cauliflower florets into the sauce, 1/4 cup cheddar cheese, salt and pepper. Mix well, until all the cauliflower is coated and the cheese is melted.
Move back to the 9x13 casserole dish, and top with remaining cheddar cheese cheese.
Spray lightly with olive oil and add bake to the hot oven for 10 minutes until the cheese is melted.
Remove from the oven, sprinkle with parsley, and serve hot.
