Quinoa Broccoli and Cheese Casserole

Our Quinoa Broccoli and Cheese Casserole is a fan favorite! It’s made with just 7 ingredients and has 29g of protein per serving (no meat involved!). Serve up this quinoa casserole recipe this Fall for the entire family!

Today, we present you a healthier spin on the classic Broccoli and Cheese Casserole, but fully equipped with quinoa for added protein! In my opinion, our Quinoa Cheesy Broccoli Casserole is even better than the real thing because it has 29g of protein per serving without compromising any flavor.

If you’re thinking the addition of quinoa is going to make this broccoli casserole take forever to prep, you’re wrong! You actually bake this casserole with uncooked quinoa, and things are ready in 60 minutes. So, what 7 ingredients do you need?

Here’s What You Need to Make Quinoa Broccoli and Cheese Casserole

• Quinoa: We used quinoa for this recipe because it’s hearty and packed with fiber!
• Broccoli: We liked using fresh broccoli instead of frozen. The end resulted with broccoli that still had a bit of a crunch. 
• Broth: You can use any kind of broth you want for this recipe. Chicken broth or vegetable broth would work!
• Milk: Creates a super creamy casserole! Use any kind of milk you like. 
• Sharp White Cheddar: We used white cheddar in this recipe. Yellow can be used, but make sure it is sharp to have a similar flavor profile. 

I’m not going to lie. This broccoli and cheese casserole pretty much tastes like mac and cheese with broccoli in it. A freaking GENIUS way to get your kiddos to eat vegetables, AMIRIGHT?! 

• Vegan Version: vegetable stock, vegan cheddar cheese, non-dairy milk. You could even add tofu or tempeh for a little vegan protein!
• Protein Boost: If you want to add even more protein inside the casserole, toss in some Instant Pot shredded chicken!
• Toppings: Top your casserole with some bread crumbs before baking. To brown them, set the broiler on low for 3-5 minutes. 
• Veggies: Feel free to toss in extra veggies like mushrooms, carrots, or anything else you like!
• Soup: Instead of the chicken broth and milk, you could totally use cream of mushroom and/or cream of chicken soup! These soups will add some flavor and creaminess. 
• Grains: Quinoa is a great source of protein and fiber, but if you don’t have any on hand or aren’t a fan, there are a few alternatives you can try. Brown rice or chopped cauliflower rice would both work well as a base for the casserole. Just be sure to adjust the cooking time based on your chosen substitute.

If the casserole has too much liquid in it at the end of the cooking time, bake for 10-15 more minutes. If you have already added the top layer of cheese, place tin foil over the top so it does not burn. Alternatively, allowing the casserole to sit for 10 minutes before serving will allow the quinoa to absorb a little more liquid. 

This casserole will last in the fridge for around 4 days! 

You sure can! This casserole is a great option for meal-prepping or feeding a crowd. Simply assemble the casserole according to the recipe instructions, then cover it tightly with plastic wrap and refrigerate for up to 24 hours. When you’re ready to bake, take it out of the fridge and let it sit at room temperature for about 30 minutes before baking as usual.

You can also bake the casserole a day before and reheat using the oven reheating method below.

​Here are a couple of reheating options:

1. Oven: Preheat to 350°F. Reheat the casserole in a dish, covered (foil or lid), for 20-25 minutes.
2. Microwave: Reheat single servings, covered (vented plastic wrap), on medium power for 1-2 minutes.

What to Serve with Quinoa Broccoli and Cheese Casserole

You could totally eat this casserole on its own, but adding a little extra to the side never hurt anyone! If you want to add a boost of protein, pair your quinoa broccoli casserole with some juicy baked chicken breast, spatchcock chicken, or rotisserie chicken. Want a little more veg? Pair your casserole with an arugula salad or a spring mix salad. Craving some carbs? Add some roasted sweet potatoes to the side.
