Healthy Broccoli Casserole
This cheesy broccoli casserole is bound to be a new favorite! It’s a lightened-up version of a classic and completely made from scratch!
Lightened Up Broccoli Casserole
When we were first married, I made what felt like a million versions of broccoli chicken casserole. None of them were very good and I swore off broccoli casserole for years. But the other day I had a ton of broccoli sitting in our fridge and so I decided to try my hand at broccoli casserole one more time.
And guess what?? This time it was DELICIOUS!
I owe it to the crispy mushrooms, the challah breadcrumbs, and the cheese. They sold me. Not only was I in love, but the hubby and toddler were too. The entire dish was gone by the end of the night!! We will definitely be making this over & over again.
Plus I love the fact that broccoli is a great vegetable choice. Its high in vitamin K and C and is also high in folic acid.
How to Make Healthy Broccoli Casserole
- Begin by preheating your oven to 350 degrees and preparing your 9×13 inch baking dish
- Steam your broccoli until they are crisp-tender (if you overcook at this stage you will get a soggy broccoli casserole and no one wants that! It is important to note that the broccoli will continue to cook as the casserole bakes in the oven.) I used a steamer bag for the broccoli and tossed it into the microwave to save time & reduce the number of dirty dishes. Put broccoli in a bowl and set to the side.
- Saute mushrooms until they are golden brown. Don’t just lightly cook them. They add so much flavor and depth to this dish… a few minutes more is going to make a huge difference
- Then add the onion and garlic and saute until they are fragrant. Once finished transfer them to the bowl of broccoli.
- Then make your roux and when its thickened remove from the heat and added salt, pepper, paprika, cayenne pepper and Greek yogurt
- Pour the sauce into the bowl with all the veggies and then add the egg, 1 cup of the cheddar cheese, and ½ cup of the breadcrumbs and pour it into the prepared baking dish.
- In the microwave melt the remaining butter and mix with the remaining breadcrumbs and cheese and use this mixture to top the broccoli mixture.
- Bake for 30-40 minutes. It should bubble and brown.
- Let it stand for 10 minutes to let it thicken up.
There are many ways you can change up this recipe.
If you don’t want to use greek yogurt, you can use light sour cream
Use whatever breadcrumbs you have- I once made this and used a leftover loaf of challah. I cut it up, toasted it and gave it a whirl in my food processor! Moral of the story-use what you have on hand!
Use fresh or frozen broccoli but note that when fresh broccoli looks yellow and becomes limp it shouldn’t be consumed!
How to Store, Reheat + Freeze
You can make this dish ahead of time and keep it uncooked in the fridge for up to 3 days. After it is baked I recommend only keeping it in the fridge for less than a week. To reheat just pop it in the microwave.
This is a great make-ahead casserole that you can freeze for a babysitter to heat up! Go ahead and prep everything except the topping. Place into a foil disposable pan and top with foil and freeze for up to 3 months!
Then finish it with the topping and go ahead and bake it, it might take a little bit longer to get warmed through if it is coming straight from the freezer. You can always take it out the night before and leave it in the fridge to thaw a little bit.
Watch this casserole disappear before your eyes. Seriously. This is a great way to get your kids to eat their veggies! Enjoy!
